Why GAO Did This Study: 

The Internal Revenue Service (IRS) and foreign tax administrators face 
similar issues regardless of the particular provisions of their laws. 
These issues include, for example, helping taxpayers prepare and file 
returns, and assuring tax compliance. Understanding how other tax 
administrators have used certain practices to address common issues 
can provide insights to help inform deliberations about tax reform and 
about possible administrative changes in the U.S. existing system to 
improve compliance, better serve taxpayers, reduce burdens, and 
increase efficiencies. 

GAO was asked to describe (1) how foreign tax administrators have 
approached issues that are similar to those in the U.S. tax system and 
(2) whether and how the IRS identifies and adopts tax administration 
practices used elsewhere. 

To do this, GAO reviewed documents and interviewed six foreign tax 
administrators. In some cases, GAO also interviewed tax experts, tax 
practitioners, taxpayers, and trade-group representatives who were 
selected based on their expertise or involvement in developing or 
using the foreign systems. GAO also examined documents and met with 
IRS officials. 

What GAO Found: 

Foreign and U.S. tax administrators use many of the same practices 
such as information reporting, tax withholding, providing Web-based 
services, and finding new approaches for tax compliance. These 
practices, although common to each system, have important differences. 
This report describes the following six foreign tax administration 
practices that address common issues in tax administration. 

Table: Selected Foreign Tax Administration Practices: 

Foreign administrator: New Zealand; 
Practice: Does integrated evaluations of tax expenditures and 
discretionary spending programs to analyze their effects and improve 
program delivery. 

Foreign administrator: Finland; 
Practice: Uses the Internet to calculate individual tax withholding 
rates and revise preprepared tax returns to improve service at lower 
costs. 

Foreign administrator: European Union; 
Practice: Uses multilateral treaty information exchange on interest 
payments to member nations’ citizens to spur compliance by individual 
taxpayers. 

Foreign administrator: United Kingdom; 
Practice: Uses information reporting and withholding so most wage 
earners do not need to file a tax return. 

Foreign administrator: Australia: 
Practice: Uses a compliance program for high-net-wealth individuals 
that focuses on their full set of business interests to improve 
compliance. 

Foreign administrator: Hong Kong; 
Practice: Uses semiannual payments instead of periodic withholding for 
the Salaries Tax.

Although differences in laws, culture, or other factors likely would 
affect the transferability of foreign tax practices to the United 
States, these practices may provide useful insights for policymakers 
and the IRS. For example, New Zealand integrates evaluations of its 
tax and discretionary spending programs. The evaluation of its Working 
For Families tax benefits and discretionary spending, which together 
financially assist low- and middle-income families to promote 
employment, found that its programs aided the transition to employment 
but that it still had an underserved population; these findings likely 
would not have emerged from separate evaluations. GAO previously has 
reported that the United States lacks clarity on evaluating tax 
expenditures and related discretionary spending programs and does not 
generally undertake integrated evaluations. In Finland, electronic tax 
administration is part of a government policy to use electronic 
services to lower the cost of government and encourage private-sector 
growth. Overall, according to Finnish officials, electronic services 
have helped to reduce Tax Administration staff by over 11 percent from 
2003 to 2009 while improving taxpayer service. 

IRS officials learn about these practices based on interactions with 
other tax administrators and participation in international 
organizations, such as the Organisation for Economic Co-operation and 
Development. In turn, the IRS may adopt new practices based on the 
needs of the U.S. tax system. For example, in 2009, the IRS formed the 
Global High Wealth Industry program. The IRS consulted with Australia 
about its approach and operational practices.

Tax administrators around the world all strive to address similar 
issues regardless of the specific provisions of their laws. These 
issues include helping taxpayers prepare and file tax returns, keeping 
track of taxes owed and paid by various types of taxpayers, and 
assuring tax compliance. Understanding how other tax administrators 
have used certain practices to address these common issues can provide 
insights to help inform deliberations about tax reform and about 
possible administrative changes in our existing system to improve 
compliance, better serve taxpayers, reduce burden, and increase 
efficiencies. To assist you in considering the potential applicability 
of foreign tax administration practices for U.S. policy and practices, 
we will describe (1) how foreign tax administrators have approached 
issues that are similar to those in the U.S. tax system and (2) 
whether and how the Internal Revenue Service (IRS) identifies and 
adopts tax administration practices used elsewhere. 

We selected six foreign tax administrators' approaches to practices 
that were different than the approach to a similar practice in the 
United States as shown in table 1. 

Table 1: Selected Foreign Tax Administration Practices: 

Foreign tax administrator: New Zealand; 
Practice: Does integrated evaluations of tax expenditures and 
discretionary spending programs to analyze their effects and improve

We based our selection of these practices on several factors, 
including whether the tax administrators had advanced economies and 
tax systems, tax information was available in English, and the foreign 
tax administrator's approach differed, at least in part, from how the 
United States approaches similar issues. We primarily used 
documentation from each government's reports that are publicly 
available. When possible, we confirmed additional information provided 
to us by officials. To identify taxpayers' attitudes toward Hong 
Kong's semiannual payment system, we interviewed experts who were 
either university professors, were the authors of publications on Hong 
Kong's tax system, or were practitioners in well-known law or 
accounting firms. To understand the development of Finland's Internet-
based withholding estimation and prepared returns system, we met with 
the public interest and trade groups that provided assistance to 
Finland's Parliament during the system's development. 

To describe whether and how the IRS identifies and adopts tax 
administration practices used elsewhere, we reviewed related documents 
and interviewed IRS officials. To help ensure the accuracy of the 
information we present, we shared a summary of our descriptions with 
representatives of the six foreign tax administrators and incorporated 
their comments as appropriate. The IRS provided technical comments 
that are included in this report. 

The descriptive information on the practices of foreign administrators 
presented in this report may provide useful insights for Congress and 
others on enhancements to current U.S. tax policies and practices. 
However, it was beyond the scope of this report to identify and assess 
the factors that might affect the transferability of the practices to 
the United States. For example, nations have differing cultures and 
differing attitudes toward government, sometimes called "tax morale." 
Generally, higher tax morale has been found to be positively related 
to high levels of voluntary tax compliance. To the extent that 
taxpayers in some countries are more willing to fully comply with tax 
rules, voluntary tax compliance is higher and less enforcement action 
is needed by the tax administrator. Thus, those nations' tax 
enforcement practices may not be as appropriate in other nations where 
citizens have lower tax morale. Measurements of tax morale generally 
are not well defined or uniform; nor are measurements of voluntary tax 
compliance. 

We conducted our work from October 2009 to May 2011 in accordance with 
all sections of GAO's Quality Assurance Framework that are relevant to 
our objectives. The framework requires that we plan and perform the 
engagement to obtain sufficient and appropriate evidence to meet our 
stated objectives and to discuss any limitations in our work. We 
believe that the information and data obtained, and the analysis 
conducted, provide a reasonable basis for any findings and conclusions 
in this report. A more detailed discussion of our methodology for each 
objective is in appendix I. 

Background: 

The IRS and tax administrators worldwide generally use similar 
administrative practices. 

Information reporting. Information reporting is a widely accepted 
practice for increasing taxpayer compliance. Under U.S. law, some 
types of transactions are required to be reported to the IRS by third 
parties who make payments to, or sometimes receive payments from, 
individual taxpayers. Typically, information returns represent income 
paid to the taxpayer, such as wages or bank account interest.[Footnote 
1] After tax returns are filed, the IRS then matches the amounts 
reported on information returns to the amounts reported on the 
taxpayer's return. For any differences, the IRS may send a notice to 
the taxpayer requesting an explanation. If the taxpayer does not 
respond to the notice, the IRS may make an additional assessment. For 
fiscal year 2010, the IRS received over 2.7 billion information 
returns, sent 5.5 million notices on differences between information 
returns and tax returns, and assessed an additional $20.7 billion in 
taxes, interest, and penalties. 

Withholding. Withholding is a widely accepted practice to increase 
taxpayer compliance. Under U.S. law, employers must withhold income 
tax from the wages paid to employees.[Footnote 2] Withholding from 
salaries requires wage earners to pay enough tax during the tax year 
to assure that they will not face a large payment at year end. Also, 
withholding can be required as a backup to information reporting if a 
payee fails to furnish a correct taxpayer identification number (TIN). 
If the payee refuses to furnish a TIN, the payer generally withholds 
28 percent of the amount of the payment--for example, interest 
payments on a bank account--and remits that amount to the IRS. 

Electronic tax administration. Many tax administrators in the United 
States and worldwide have increasingly used electronic tax 
administration to improve services and reduce costs. The IRS has 
focused its electronic tax administration on filing tax returns over 
the Internet, providing taxpayer assistance through its Web site, and 
providing telephone assistance. To accept electronically filed tax 
returns, IRS has authorized preapproved e-file providers to submit the 
returns. IRS cannot accept electronically filed returns directly from 
taxpayers. Through its Web site, IRS provides taxpayers with 
publications explaining tax law and IRS administrative procedure. The 
Web site also provides automated services such as "Where's My Refund?" 
During the 2010 filing season, the IRS Web site had 239 million total 
visits and 277 million searches. IRS also received 77 million 
telephone calls of which IRS phone assistors answered about 24 million 
calls.[Footnote 3] 

Tax enforcement. The U.S. tax system, as well as many other tax 
systems worldwide, is based on some degree of self-reporting and 
voluntary compliance by taxpayers. Tax administrations worldwide have 
enforcement programs to ensure that tax returns are accurate and 
complete and taxes are paid. Among others, IRS uses two principal 
enforcement programs. After tax returns have been filed, the Automated 
Underreporter Program matches data on information returns (usually on 
income) provided by employers, banks, and other payers of income to 
data reported on taxpayers' tax returns. IRS may contact taxpayers 
about any differences. The Examination Program relies on IRS auditors 
to check compliance in reporting income, deductions, credits, and 
other issues on tax returns by reviewing the documents taxpayers 
provided to support their tax return. 

IRS, like revenue agencies in many countries, administers tax 
expenditures. Tax expenditures are tax provisions that grant special 
tax relief for certain kinds of behavior by taxpayers or for taxpayers 
in special circumstances. Tax expenditures reduce the amount of taxes 
owed and therefore are seen as resulting in the government forgoing 
revenues. These provisions are viewed by many analysts as spending 
channeled through the tax system. For fiscal year 2010, the U.S. 
Department of the Treasury reported 173 tax expenditures costing, in 
aggregate, more than $1 trillion.[Footnote 4] Tax expenditures are 
often aimed at policy goals similar to those of federal spending 
programs, such encouraging economic development in disadvantaged areas 
and financing postsecondary education. In 2005, we reported that all 
U.S. federal spending and tax policy tools, including tax 
expenditures, should be reexamined to ensure that they are achieving 
their intended purposes and designed in the most efficient and 
effective manner.[Footnote 5] 

Examples of Selected Tax Administration Practices to Address Known Tax 
Administration Issues: 

The following examples illustrate how New Zealand, Finland, the 
European Union (EU), the United Kingdom (UK), Australia, and Hong Kong 
have addressed well-known tax administration issues.[Footnote 6] Our 
work does not suggest that these practices should or should not be 
adopted by the United States. 

New Zealand Does Integrated Evaluations of Tax Expenditures and 
Discretionary Spending Programs to Analyze Their Effects and Improve 
Program Delivery: 

New Zealand, like the United States, addresses various national 
objectives through a combination of tax expenditures and discretionary 
spending programs. In New Zealand, tax expenditures are known as tax 
credits. New Zealand has overcome obstacles to evaluating these 
related programs at the same time to better judge whether they are 
working effectively. Rather than doing separate evaluations, New 
Zealand completes integrated evaluations of tax expenditures and 
discretionary spending programs to analyze their combined effects. 
Using this approach, New Zealand can determine, in part, whether tax 
expenditures and discretionary spending programs work together to 
accomplish government goals. 

One example is the Working For Families (WFF) Tax Credits program, 
which is an entitlement for families with dependent children to 
promote employment. Prior to the introduction of WFF in 2004, New 
Zealand's Parliament discovered that many low-income families were not 
better off from holding a low-paying job, and those who needed to pay 
for childcare to work were generally worse off in low-paid work 
compared to receiving government benefits absent having a job. This 
prompted Parliament to change its in-work incentives and financial 
support including tax expenditures. 

The WFF Tax Credits program differs from tax credit programs in the 
United States in that it is an umbrella program that spans certain tax 
credits administered by the Inland Revenue Department (IRD) as well as 
discretionary spending programs administered by the Ministry of Social 
Development (MSD). IRD collects most of the revenue and administers 
the tax expenditures for the government. Being responsible for 
collecting sensitive taxpayer information, IRD must maintain tax 
privacy and protect the integrity of the New Zealand tax system. MSD 
administers the WFF's program funds and is responsible for collecting 
data that include monthly income received by its beneficiaries. Given 
different responsibilities, IRD and MSD keep separate datasets, making 
it difficult to assess the cumulative effect of the WFF program. 

Therefore, to understand the cumulative effect of changes made to the 
WFF program and ensure that eligible participants were using it, New 
Zealand created a joint research program between IRD and MSD that ran 
from October 2004 to April 2010. The joint research program created 
linked datasets between IRD and MSD. Access to sensitive taxpayer 
information was restricted to IRD employees on the joint research 
program and to authorized MSD employees only after they were sworn in 
as IRD employees. 

The research provided information on key outcomes that could only be 
tracked through the linked datasets. The research found that the WFF 
program aided the transition from relying on government benefits to 
employment, as intended. It also found that a disproportionate number 
of those not participating in the program faced barriers to taking 
advantage of the WFF. Barriers included the perceived stigma from 
receiving government aid, the transaction costs of too many rules and 
regulations, and the small amounts of aid for some participants. On 
the basis of these findings, Parliament made changes to WFF that 
provided an additional NZ$1.6 billion (US$1.2 billion) per year in 
increased financial entitlements and in-work support to low-to middle-
income families.[Footnote 7] 

Appendix II provides more details on New Zealand's evaluation of tax 
expenditures as well as similarities and differences to the U.S. 
system. 

Finland Uses the Internet to Calculate Individual Tax Withholding 
Rates and Revise Preprepared Tax Returns to Improve Service at Lower 
Costs: 

Finland encourages accurate withholding of taxes from taxpayers' 
income, lowers its costs, and reduces taxpayers' filing burdens 
through Internet-based electronic services. In 2006, Finland 
established a system, called the Tax Card, to help taxpayers estimate 
a withholding rate for the individual income tax. The Tax Card, based 
in the Internet, covers Finland's national tax, municipality tax, 
social security tax, and church tax.[Footnote 8] The Tax Card is 
accessed through secured systems in the taxpayer's Web bank or an 
access card issued by Finland's government. The Tax Card system 
enables taxpayers to update their withholding rate as many times as 
needed throughout the year, adjusting for events that increase or 
decrease their income tax liability. When completed, the employer is 
notified of the changed withholding tax rate through the mail or by 
the employee providing a copy to the employer. According to the Tax 
Administration, about a third of all taxpayers using the Tax Card--
about 1.6 million people--change their withholding percentages at 
least annually. Finland generally refunds a small amount of the 
withheld funds to taxpayers (e.g., it refunded about 8 percent of the 
withheld money in 2007). 

Finland also has been preparing income tax returns for individuals 
since 2006. The Tax Administration prepares the return for the tax 
year ending on December 31st based on third-party information returns, 
such as reporting by employers on wages paid or by banks on interest 
paid to taxpayers. During April, the Tax Administration mails the 
preprepared return for the taxpayer's review. Taxpayers can revise the 
paper form and return it to the Tax Administration in the mail or 
revise the return electronically online. According to Tax 
Administration officials, about 3.5 million people do not ask to 
change their tax return and about 1.5 million will request a tax 
change. 

Electronic tax administration is part of a governmentwide policy to 
use electronic services to lower the cost of government and encourage 
growth in the private sector. According to Tax Administration staff, 
increasing electronic services to taxpayers helps to lower costs. 
Overall, the growth of electronic services, according to Finnish 
officials, has helped to reduce Tax Administration staff by over 11 
percent from 2003 to 2009 while improving taxpayer service. 

According to officials of the Finnish government as well as public- 
interest and trade groups, the Tax Card and preprepared return systems 
were established under a strong culture of national cooperation. For 
the preprepared return system to work properly, Finland's business and 
other organizations that prepare information returns had to accept the 
burden to comply in filing accurate returns promptly following the end 
of the tax year. 

Finland's tax system is positively viewed by taxpayers and industry 
groups, according to our discussions with several industry and 
taxpayer groups. They stated that Finland has a simple, stable tax 
system which makes compliance easier to achieve. As a result, few 
individuals use a tax advisor to help prepare and file their annual 
income tax return. 

Appendix III provides more details on Finland's electronic tax 
administration system as well as a discussion of similarities to and 
differences from the U.S. system. 

EU's Multilateral Treaty Information Exchange on Interest Payments to 
Member Nations' Citizens to Spur Compliance by Individual Taxpayers: 

The EU seeks to improve tax compliance through a multilateral 
agreement on the exchange of information on interest earned by each 
nation's individual taxpayers. This agreement addresses common issues 
with the accuracy and usefulness of information exchanged among 
nations that have differing technical, language, and formatting 
approaches for recording and transmitting such information. Under the 
treaty, called the Savings Taxation Directive, adopted in June 2003, 
the 27 EU members and 10 other participants agreed to share 
information about income from interest payments made to individuals 
who are citizens in another member nation. With this information, the 
tax authorities are able to verify whether their citizens properly 
reported and paid tax on the interest income. The directive provides 
the basic framework for the information exchange, defining essential 
terms and establishing automatic information exchange among members. 
[Footnote 9] 

As part of the directive, 3 EU member nations as well as the 5 
European nonmember nations agreed to apply a withholding tax with 
revenue sharing (described below) during a transition period through 
2011, rather than automatically exchanging information.[Footnote 10] 
Under this provision, a 15 percent withholding tax gradually increases 
to 35 percent by July 1, 2011. The withholding provision included a 
revenue-sharing provision, which authorizes the withholding nation to 
retain 25 percent of the tax collected and transfer the other 75 
percent to the nation of the account owner. The directive also 
requires the account owner's home nation to ensure that withholding 
does not result in double taxation. The directive does this by 
granting a tax credit equal to the amount of tax paid to the nation in 
which the account is located. 

A September 2008 report to the EU Council described the status of the 
directive's implementation. During the first 18 months of information 
exchange and withholding, data limitations such as incomplete 
information on the data exchanged and tax withheld created major 
difficulties for evaluating the directive's effectiveness. Further, no 
benchmark was available to measure the effect of the changes. 

According to EU officials, the most common administrative issues, 
especially during the first years of implementation of the directive, 
have been the identification of the owner reported in the computerized 
format. It is generally recognized that a Taxpayer Identification 
Number (TIN) provides the best means of identifying the owner. 
However, the current directive does not require paying agents to 
record a TIN. Using names has caused problems when other EU member 
states tried to access the data. For example, a name that is 
misspelled cannot be matched. In addition, how some member states 
format their mailing address may have led to data-access problems. 

Other problems with implementing the directive include identifying 
whether investors moved their assets into categories not covered by 
the directive (e.g., shifting to equity investments), and concerns 
that tax withholding provisions may not be effective because 
withholding rates were low until 2011 when the rate became 35 percent. 
The EU also identified problems with the definition of terms, making 
uniform application of the directive difficult. Generally these terms 
identify which payments are covered by the directive, who must report 
under the directive, and who owns the interest for tax purposes. 

Nevertheless, EU officials stated that the quality of data has 
improved over the years. The EU officials have worked with EU member 
nations to resolve specific data issues, which has contributed to the 
effective use of the information exchanged under the directive. EU 
officials told us that the monitoring role by the EU Commission, the 
data-corrections process, and frequent contacts to resolve specific 
issues have contributed to effective use of the data received by EU 
member states. 

Appendix IV provides more details on the EU Saving Taxation Directive 
and related issues such as avoiding double taxation as well as a 
discussion of similarities to and differences from the U.S. system. 

UK Uses Information Reporting and Withholding So Most Wage Earners Do 
Not Need to File a Tax Return: 

The UK promotes accurate tax withholding and reduces taxpayers' filing 
burdens by calculating withholding rates for taxpayers and requiring 
that payers of certain types of income withhold taxes at standard 
rates. The UK uses information reporting and withholding to simplify 
tax reporting and tax payments for individual tax returns. Both the 
individual taxpayer and Her Majesty's Revenue and Customs (HMRC)--the 
tax administrator--are to receive information returns from third 
parties that make payments to a taxpayer such as for bank account 
interest. 

A key element is the UK's Pay As You Earn (PAYE) system. Under the 
PAYE system, HMRC calculates an amount of withholding from wages to 
meet a taxpayer's liability for the current tax year based on 
information reporting from the employer and other income information 
employees may provide. According to HMRC officials, the individual tax 
system in the UK is simple for most taxpayers who are subject to PAYE. 
PAYE makes it unnecessary for wage earners to file a yearly tax 
return, unless special circumstances apply. For example, wage earners 
do not need to file a return unless income from interest, dividends, 
or capital gains exceeds certain thresholds or if deductions need to 
be reported. Therefore, a tax return may not be required because most 
individuals do not earn enough of these income types to trigger self-
reporting. For example, the first £10,100 (US$16,239) of capital gains 
income is exempt from being reported on tax returns.[Footnote 11] 

PAYE also facilitates the reconciliation of tax liabilities for prior 
tax years through the use of withholding at source for wages. The 
withheld amount may be adjusted by HMRC to collect any unpaid taxes 
from previous years or refund overpayments. HMRC annually notifies the 
taxpayer and employer of the amount to withhold. 

HMRC also may adjust the withheld amount through information provided 
by taxpayers. If taxpayers provide the information on their other 
income such as self-employment earnings, rental income, or investment 
income, HMRC can adjust the PAYE withholding. Individuals not under 
the PAYE system are required to file a tax return after the end of the 
tax year based on their records. 

In addition, HMRC uses information reporting and tax withholding as 
part of its two-step process to assess the compliance risks on filed 
returns. In the first step, individual tax returns are reviewed for 
inherent compliance risks because of the taxpayers' income level and 
complexity of the tax return. For example, wealthy taxpayers with 
complex business income are considered to have a higher compliance 
risk than a wage earner. In the second step, information compiled from 
various sources--including information returns and public sources--is 
analyzed to identify returns with a high compliance risk. According to 
HMRC officials, these assessments have allowed HMRC to look at 
national and regional trends. HMRC is also attempting to uncover 
emerging compliance problems by combining and analyzing data from the 
above sources as well as others. 

Appendix V provides more details on the UK's information reporting and 
withholding system as well as a discussion of similarities to and 
differences from the U.S. system. 

Australia Uses a Compliance Program for High-Net-Wealth Individuals 
That Focuses on Their Full Set of Business Interests to Improve 
Compliance: 

The Australian High Net Wealth Individuals (HNWI) program focuses on 
the characteristics of wealthy taxpayers that affect their tax 
compliance. High-wealth individuals often have complex business 
relationships involving many entities they may directly control or 
indirectly influence and these relationships may be used to reduce 
taxes illegally or in a manner that policymakers may not have 
intended. The HNWI program requires these taxpayers to provide 
information on these relationships and provides such taxpayers 
additional guidance on proper tax reporting. 

According to the Australian Taxation Office (ATO), in the mid-1990s, 
ATO was perceived as enforcing strict sanctions on the average 
taxpayers but not the wealthy. By 2008, ATO found that high-wealth 
taxpayers, those with a net worth of more than A$30 million (US$20.9 
million), had substantial income from complex arrangements,[Footnote 
12] which made it difficult for ATO to identify and assure compliance. 
ATO concluded that the wealthy required a different tax administration 
approach. 

ATO set up a special task force to improve its understanding of 
wealthy taxpayers, identify their tax planning techniques, and improve 
voluntary compliance. Due to some wealthy taxpayers' aggressive tax 
planning, which ATO defines as investment schemes and legal structures 
that do not comply with the law, ATO quickly realized that it could 
not reach its goals for voluntary compliance for this group by 
examining taxpayers as individual entities. To tackle the problem, ATO 
began to view wealthy taxpayers as part of a group of related business 
and other entities. Focusing on control over related entities rather 
than on just individual tax obligations provided a better 
understanding of wealthy individuals' compliance issues. 

The HNWI approach followed ATO's general compliance model. The model's 
premise is that tax administrators can influence tax compliance 
behavior through their responses and interventions. For compliant 
wealthy taxpayers, ATO developed a detailed questionnaire and expanded 
the information on business relationships that these taxpayers must 
report on their tax return. For noncompliant wealthy taxpayers, ATO is 
to assess the tax risk and then determine the intensity of ATO's 
compliance interventions. 

According to 2008 ATO data, the HNWI program has produced financial 
benefits. From the establishment of the program in 1996 until 2007, 
ATO had collected A$1.9 billion (US$1.67 billion) in additional 
revenue and reduced revenue losses by A$1.75 billion (US$1.5 billion) 
through compliance activities focused on highly wealthy individuals 
and their associated entities.[Footnote 13] ATO's program focus on 
high-wealth individuals and their related entities has been adopted by 
other tax administrators. By 2009, nine other countries, including the 
United States, had formed groups to focus resources on high-wealth 
individuals. 

Appendix VI provides more details on Australia's high-wealth program 
as well as similarities and differences to the U.S. system. 

Hong Kong Uses Semiannual Payments Instead of Periodic Employer 
Withholding for the Salaries Tax: 

Although withholding of taxes by payers of income is a common practice 
to ensure high levels of taxpayer compliance, Hong Kong's Salaries Tax 
does not require withholding by employers. Instead, tax administrators 
and taxpayers appear to find a semiannual payment approach effective. 
Hong Kong's Salaries Tax is a tax on wages and salaries with a small 
number of deductions (e.g., charitable donations and mortgage 
interest). The Salaries Tax is paid by about 40 percent of the 
estimated 3.4 million wage earners in Hong Kong, while the other 60 
percent are exempt from Salaries Tax. 

Rather than using periodic (e.g., biweekly or monthly) tax withholding 
by employers, Hong Kong collects the Salaries Tax through two payments 
by taxpayers for a tax year. Since the tax year runs for April 1st 
through March 31st, a substantial portion of income for the tax year 
is earned by January (i.e., income for April to December), and the 
taxpayer is to pay 75 percent of the tax for that tax year in January 
(as well as pay any unpaid tax from the previous year). The remaining 
25 percent of the estimated tax is to be paid 3 months later in April. 

By early May, the Inland Revenue Department (IRD)--the tax 
administrator--annually prepares individual tax returns for taxpayers 
based on information returns filed by employers. Taxpayers review the 
prepared return, make any revisions such as including deductions 
(e.g., charitable contributions), and file it with IRD. IRD then will 
review the returns and determine if any additional tax is due. If the 
final Salaries Tax assessment turns out to be higher than the 
estimated tax previously assessed, IRD is to notify the taxpayer, who 
is to pay the additional tax concurrently with the January payment of 
estimated tax for the next tax year. 

Hong Kong's tax system is positively viewed by tax experts, 
practitioners, and a public opinion expert based on our discussions 
with them. They generally believe that low tax rates, a simple system, 
and cultural values contribute to Hong Kong's collection of the 
Salaries Tax through the two payments rather than periodic 
withholding. Tax rates are fairly low, starting at 2 percent of the 
adjusted salary earned and not exceeding 15 percent. Further, tax 
experts told us that the Salaries Tax system is simple. Few taxpayers 
use a tax preparer because the tax form is very straightforward and 
the tax system is described as "stable." Further, an expert on public 
opinion in Hong Kong told us that taxpayers fear a loss of face if 
recognized as not complying with tax law. This cultural attitude helps 
promote compliance. 

Appendix VII provides more details on Hong Kong's Salaries Tax system 
as well as a discussion of similarities to and differences from the 
U.S. system. 

IRS Considers Foreign Tax Practices That Might Merit Adoption: 

IRS officials learn about foreign tax practices by participating in 
international organizations of tax administrators. IRS is actively 
involved in two international tax organizations and one jointly run 
program that addresses common tax administration issues. First, the 
IRS participates with the Center for Inter-American Tax Administration 
(CIAT), a forum made up of 38 member countries and associate members, 
which exchange experiences with the aim of improving tax 
administration. CIAT, formed in 1967, is to promote integrity, 
increase tax compliance, and fight tax fraud. The IRS participates 
with CIAT in designing and developing tax administration products and 
with CIAT's International Tax Planning Control committee.[Footnote 14] 
Second, the IRS participates with the Organisation for Economic Co-
operation and Development (OECD) Forum on Tax Administration (FTA), 
which is chaired by the IRS Commissioner during 2011. The FTA was 
created in July 2002 to promote dialogue between tax administrations 
and identify good tax administration practices. Since 2002, the forum 
has issued over 50 comparative analyses on tax administration issues 
to assist member and selected nonmember countries. 

IRS and OECD officials exchange tax administration knowledge. For 
example, the IRS is participating in the OECD's first peer review of 
information exchanged under tax treaties and tax information exchange 
agreements. Under the peer-review process, senior tax officials from 
several OECD countries examine each selected member's legal and 
regulatory framework and evaluate members' implementation of OECD tax 
standards. The peer-review report on IRS information exchange 
practices is expected to be published in mid-2011. 

As for the jointly run program, the Joint International Tax Shelter 
Information Centre (JITSIC) attempts to supplement ongoing work in 
each country to identify and curb abusive tax schemes by exchanging 
information on these schemes. JITSIC was formed in 2004 and now 
includes tax agencies of Australia, Canada, China, Japan, South Korea, 
the United Kingdom, and the United States. According to the IRS, 
JITSIC members have identified and challenged the following highly 
artificial arrangements: 

* a cross-border scheme involving millions of dollars in improper 
deductions and unreported income on tax returns from retirement 
account withdrawals; 

* highly structured financing transactions created by financial 
institutions that taxpayers used to generate inappropriate foreign tax 
credit benefits;[Footnote 15] and: 

* made-to-order losses on futures and options transactions for 
individuals in other JITSIC jurisdictions, leading to more than $100 
million in evaded taxes. 

To date, the IRS has implemented one foreign tax administration 
practice. As presented earlier, Australia's HNWI program examines 
sophisticated legal structures that wealthy taxpayers may use to mask 
aggressive tax strategies. In 2009, the OECD issued a report for a 
project on the tax compliance problems of wealthy individuals and 
concluded that "high net worth individuals pose significant challenges 
to tax administrations" due to their complex business dealings across 
different business entities, higher tax rates, and higher likelihood 
of using aggressive tax planning or tax evasion.[Footnote 16] 
According to an IRS official, during IRS's participation in 2008 in 
the OECD Project, IRS staff began to realize the value of Australia's 
program to the U.S. tax system. The IRS now has a program focused on 
wealthy individuals and their networks.[Footnote 17]

Appendix I: Scope and Methodology: 

For our objective to describe how other countries have approached tax 
administration issues that are similar to those in the U.S. tax 
system, we selected six foreign tax administrators. We based our 
selection of these practices on several factors, including whether the 
tax administrators had advanced economies and tax systems and the 
foreign tax administrator's approach differed, at least in part, from 
how the United States approaches similar issues. These tax systems 
also needed to have enough information available in English on their 
Web site for us to preliminarily understand their tax system and 
practices. In addition, we considered practices of interest to the 
requesters. 

To describe each of the practices, we reviewed documents and held 
telephone conferences with officials from each tax administrator. We 
also met with officials of Finland's government in Helsinki. When 
possible, we confirmed additional information provided to us by 
officials to assure that we had a reasonable basis for the data 
presented. We used official reports published by the tax 
administrators, such as their annual reports, that are made available 
to the public on their Internet Web site. To identify taxpayers' 
attitudes toward Hong Kong's semiannual payment system, we interviewed 
experts who were either university professors, were the authors of 
publications on Hong Kong's tax system, or were practitioners in well- 
known law or accounting firms. To understand the development of 
Finland's Internet-based withholding estimation and prepared returns 
system, we met with the public interest and trade groups that provided 
assistance to Finland's Parliament during the system's development. 

To describe whether and how the Internal Revenue Service (IRS) 
identifies and integrates tax administration practices used in other 
countries, we interviewed IRS officials and reviewed related 
documents. We also followed up with IRS officials based on any 
information we found independently about practices that relate to 
issues in the U.S. tax system and our comparison of U.S. and other 
administrator's practices. The descriptive information on the 
practices of foreign administrators presented in this report may 
provide useful insights for Congress and others on alternatives to 
current U.S. tax policies and practices. However, our work did not 
include the separate analytic step of identifying and assessing the 
factors that might affect the transferability of the practices to the 
United States.[Footnote 18] 

To adjust foreign currencies to U.S. dollars, we used the Federal 
Reserve Board's database on foreign exchange rates. We used rates that 
matched the time period cited for the foreign amount. For current 
amounts, we used the exchange rates published for February 25, 2011. 
If the amounts were for a previous year, we used the exchange rate 
published for the last business day of that year. For example, if 
foreign amounts were cited as of 2006, we used exchange rates for 
December 29, 2006. We did not adjust amounts from previous years for 
inflation. 

To help ensure the accuracy of the information we present, we shared a 
summary of our descriptions with representatives of the six foreign 
tax administrators and incorporated their comments as appropriate. The 
IRS provided technical comments that are included in this report. 

We conducted our work from October 2009 to May 2011 in accordance with 
all sections of GAO's Quality Assurance Framework that are relevant to 
our objectives. The framework requires that we plan and perform the 
engagement to obtain sufficient and appropriate evidence to meet our 
stated objectives and to discuss any limitations in our work. We 
believe that the information and data obtained, and the analysis 
conducted, provide a reasonable basis for any findings and conclusions 
in this report.

Appendix II: New Zealand Does Integrated Evaluations of Tax 
Expenditures and Discretionary Spending Programs: 

Overview of the New Zealand Tax System: 

The New Zealand tax system is centralized through the Inland Revenue 
Department (IRD). Most of New Zealand's NZ$49 billion (US$35.5 
billion) in revenue for fiscal year 2009 was raised by direct taxation 
that includes PAYE (Pay As You Earn), Company Tax, and Schedular 
Payments.[Footnote 19] In addition, tax expenditures (tax credits in 
New Zealand) for social programs that were administered by IRD in 2009 
include KiwiSaver and Working For Families (WFF) Tax Credits programs. 
[Footnote 20] 

What Is New Zealand's Working For Families Tax Credits Program? 

The WFF Tax Credits program, started in 2004, seeks to assist low-to 
middle-income families with the goal of promoting employment and 
ensuring income adequacy. Prior to 2004, New Zealand had another 
program intended to assist families. However, the New Zealand 
government discovered that many low-income families were no better off 
from holding a low-paying job and that those who needed to pay for 
childcare to work generally were worse off in low-paid work compared 
to only receiving government benefits. This prompted the government to 
change in-work incentives and financial support for families with 
dependent children. These changes were incorporated into the WFF 
program in 2004. It was estimated that program costs would increase by 
NZ$1.6 billion (US$1.2 billion) per year. 

The WFF Tax Credits program is an umbrella program that spans certain 
tax credits[Footnote 21] administered by the IRD as well as 
discretionary spending programs[Footnote 22] administered by the 
Ministry of Social Development (MSD). Table 2 shows the tax and 
discretionary spending components of the WFF tax credits program and 
the agency responsible for them. 

Table 2: Joint Administration of New Zealand's WFF Tax Credits Program:

Source: GAO analysis of New Zealand data. 

[End of table] 

Under the program IRD makes payments to the majority of eligible 
recipients during the tax year.[Footnote 23] The IRD and MSD portions 
of the WFF tax credit program are intended to work together to assist 
low-to middle-income families and promote employment. 

Information that IRD collects and uses in administering the tax 
credits is subject to New Zealand's protections for the privacy of 
sensitive taxpayer information contained in the Tax Administration 
Act. The information that MSD collects and uses is not subject to the 
same restrictions. To meet their separate needs, IRD and MSD keep 
separate datasets. 

Why New Zealand Used Joint Research to Evaluate WFF Direct Benefit 
Payments and Tax Expenditures: 

New Zealand's joint research projects integrated research between IRD 
and other governmental agencies with related programs. The projects 
were designed to ensure that all disbursements of revenue through 
either direct program outlays or tax expenditures were administered 
effectively to meet the goals for social programs, making sure people 
get the assistance to which they are entitled. 

One example of joint research was the study of the WFF tax credits 
program. To overcome the problem of the separate datasets and still 
protect sensitive tax data, the New Zealand government approved a 
joint research program that created interagency linked datasets 
between IRD and MSD. Parliament intended that these linked datasets be 
used to evaluate the tax expenditures and discretionary spending 
programs, to ensure that the benefits of the overall program were 
being fully used by its participants. 

These linked datasets, known as the "WFF Research Datasets," were 
constructed from the combined records of the MSD and IRD. They 
contained several years of data, and included information about all 
families who had received a WFF payment during these years. The data 
included monthly amounts of income received from salary and wages from 
employment and from the main benefit payments. The linked dataset 
information was to be used solely to analyze the results of WFF. It 
could not be used to take any action, whether adverse or favorable, 
against a particular individual. 

In 2004, MSD and IRD developed a Memorandum of Understanding (MOU) for 
the WFF program. The MOU included processes to share information while 
ensuring that all sensitive data were protected from unauthorized 
disclosure. The MOU permitted IRD to provide MSD with aggregate 
taxpayer information needed to conduct evaluations with a restriction 
that only allows IRD employees direct access to sensitive taxpayer 
information. However, IRD was authorized to distribute sensitive 
taxpayer information to authorized MSD employees if they were part of 
the joint research team and were sworn in as IRD employees. Swearing 
in MSD agents as IRD agents permitted IRD to apply the same sanctions 
to IRD and MSD agents who did not adhere to IRD's data-protection 
policies. 

What Are the Known Results and Effects of the Joint Research Project? 

The WFF joint research revealed social and cultural barriers that 
prevented targeted participants from taking full advantage of the WFF 
program. These barriers included the: 

* perceived stigma from receiving government aid if the person could 
work or felt that the aid infringed on independence or self- 
sufficiency; 

* transaction costs from accepting government aid such as taking time 
off from work, arranging childcare, or following many rules and 
regulations; 

* low value of applying for the program when the person was close to 
the maximum eligibility threshold; and: 

* geographic barriers when the person lived in areas that were remote 
or had no transportation, telephone, or Internet. 

The WFF joint research provided information needed to identify the 
population that benefited from the program and reduce some of the 
barriers that kept recipients, particularly an indigenous population, 
from participating in the target program. Since the inception of the 
WFF program in 2004, the joint research documented the following 
benefits from reducing barriers to the targeted population: 

* The percentage of single parents working 20 hours or more increased 
from 48 percent in June 2004 to 58 percent in June 2007. This 
represents 8,100 additional single parents in the workforce. 

* The number of single parents receiving benefits from MSD fell by 12 
percent from March 2004 to March 2008. Those that received the 
benefits did so for a shorter time and stayed off the benefit programs 
longer. 

Similarities to and Differences from the U.S. Tax System: 

While structural differences exist between the New Zealand and U.S. 
tax systems, both systems use tax expenditures (i.e., tax credits in 
New Zealand). Unlike the United States, New Zealand has developed a 
method to evaluate the effectiveness of tax expenditures and 
discretionary spending programs through joint research that created 
interagency linked datasets. New Zealand did so while protecting 
confidential tax data from unauthorized disclosure. 

In 2005, we reported that the United States had substantial tax 
expenditures but lacked clarity on the roles of the Office of 
Management and Budget (OMB), Department of the Treasury, IRS, and 
federal agencies with discretionary spending programs to evaluate the 
tax expenditures.[Footnote 24] Consequently, the United States lacked 
information on how effective tax expenditures were in achieving their 
intended objectives, how cost-effectively benefits were achieved, and 
whether tax expenditures or discretionary spending programs worked 
well together to accomplish federal objectives.[Footnote 25] At that 
time, OMB disagreed with our recommendations to incorporate tax 
expenditures into federal performance management and budget review 
processes, citing methodological and conceptual issues. However, in 
its fiscal year 2012 budget guidance, OMB instructed agencies, where 
appropriate, to analyze how to better integrate tax and spending 
policies that have similar objectives and goals.[Footnote 26]

Appendix III: Finland Uses the Internet to Calculate Individual Tax 
Withholding Rates and Revise Preprepared Tax Returns: 

Overview of the Finland Tax System: 

Finland's national and municipal governments as well as local church 
councils levy taxes. Nationally, 39 percent of all taxes are paid 
under individual and corporate income taxes and a capital gains tax. 
Taxes on goods, services, and property total about 33 percent of 
revenue; most of this revenue is from the Value Added Tax (VAT). The 
final 28 percent comes from social security taxes (e.g., national 
health insurance system and employment pension insurance). Finland's 
individual income tax is levied on a graduated rate schedule with four 
tax brackets, ranging from 7.0 percent to 30.5 percent for incomes 
over €64,500 (US$92,441) with the tax on investment income levied at a 
flat rate of 28 percent in 2009. Finland's corporate income tax is 
levied at a flat rate of 26 percent. 

Under the municipal tax, each municipal council sets its tax rate 
annually. For 2009, municipal taxes are levied at flat rates ranging 
from 16.5 percent to 21.0 percent of earned income and averaging 18.6 
percent. Individuals who are members of the Evangelical-Lutheran 
Church or the Orthodox Church pay a church tax. For 2009, local church 
communities determine the rate of tax, which is levied at a flat rate 
between 1 and 2 percent. 

How Do Withholding Estimation and Preprepared Returns Improve Service? 

Using electronic means, Finland helps taxpayers in estimating their 
tax withholding and by preparing an income tax return for each 
individual taxpayer based on third-party information returns. The on-
line Tax Card system, established in 2006, is an Internet-based system 
to help Finnish taxpayers estimate the withholding rate for individual 
income tax. The Tax Card covers national taxes, municipality tax, 
social security tax, and church tax. Taxpayers access the Tax Card 
through the Web sites of their bank or the Finland Tax Administration. 

Using the Tax Card system, taxpayers can update their withholding rate 
as many times as needed throughout the year to adjust for events that 
increase or decrease their potential tax liability. For example, if 
the taxpayer takes a job with a higher salary, the taxpayer can 
estimate the change on his or her income tax liability by using the 
Tax Card system. Taxpayers enter information provided by the employer, 
based on payroll information, to estimate their adjusted withholding. 
Annually, 1.6 million taxpayers, about a third of those using the Tax 
Card, change their tax withholding rate. 

When the Tax Card has been completed, employees provide the 
withholding tax rate to their employer through regular mail or in 
person. If the employer is not notified of any withholding rate, the 
employer must withhold at the top marginal rate in Finland for all 
types of taxes--which is 60 percent of gross pay. Employers manually 
enter the withholding rate into their payroll systems. 

According to Tax Administration officials, some social benefits can 
complicate the estimation of the tax due and may not be accurately 
estimated during the tax year. For example, Finland has a deduction 
for the cost of travel between a residence and work. If the taxpayer 
does not accurately estimate the deductions or make changes as the 
year progresses, the Tax Card withholding rate will be inaccurate. 

Finland Tax Administration Prepares Returns for Taxpayers: 

Finland has been operating a tax-return preparation system since 2006. 
The Finnish Tax Administration prepares an income tax return for each 
individual taxpayer based on third-party information returns. 
According to Tax Administration officials, Finland uses information 
from over 30 types of information-return filers (e.g., employers, 
banks, and securities brokers). Tax Administration officials said that 
they have found very little misreporting on the information returns 
used to prepare the tax returns. They use many ways to try to verify 
the information. Some taxpayers will correct information returns when 
reviewing their prepared tax returns. Third parties can be penalized 
for inaccurate information and Finnish tax officials said those 
penalties are regularly assessed. 

The system prepares the return each tax year, which ends on December 
31. According to Tax Administration officials, the individual tax 
returns are mailed for review during April. The taxpayer has until May 
to make changes to the paper return.[Footnote 27] Taxpayers can mark 
up the paper return for revisions and mail it to the Tax 
Administration whose staff keys in or electronically scans in the 
changes. Also, taxpayers can choose to make the changes to the return 
online, using the taxpayer's account with the Tax Administration. 

According to Tax Administration officials, typically about 3.5 million 
people do not ask to change their tax return and about 1.5 million 
request a tax change. About 400,000 taxpayers will revise their return 
using the Tax Administration's Internet portal. Typically, the average 
taxpayer takes about half an hour to do the adjustments online. One 
deduction, the commuting adjustment, is not reported on an information 
return. This adjustment accounts for changes to about 800,000 prepared 
returns. 

Overall, taxpayers need to show some proof to support the change to 
the prepared return, including any changes they make to the 
information returns the Tax Administration used to prepare the 
returns. For example, taxpayers showing deductions for mortgage 
interest that were not reported on information returns would need to 
show they own a house and the mortgage interest was paid. Or, if an 
information return reports interest as income, but taxpayers deduct 
the interest as paid on a loan, the taxpayers need to document the 
reason for their deduction claims. 

Finland does not prepare tax returns if individual taxpayers have 
business income. Rather, these taxpayers must file tax returns based 
on the data or business records that they maintained. However, some of 
these taxpayers with business income may get a partially prepared 
return on personal income and deductions based on third party 
information on their wages and other personal income in Finland's 
prepared return system. All businesses operating in Finland must 
register with the government.[Footnote 28] 

Why Did Finland Increase Its Use of Electronic Tax Administration? 

Providing enhanced electronic services has been widely recognized in 
Finland as an approach for improving taxpayer service while reducing 
costs. Electronic services provide taxpayers with constant access to 
assistance regardless of the time of day or distance from the tax 
administration office. According to Tax Administration officials, 
electronic systems that provide routine taxpayer assistance allows Tax 
Administration staff to respond to more complex taxpayer problems. 

Finland also moved to electronic tax administration to support 
national policies. As a national policy to encourage economic growth, 
Finland seeks to have a large private-sector workforce. According to 
an official of the Finland's government, a large number of citizens 
are nearing retirement.[Footnote 29] Thus, the government is seeking 
to reduce its workforce so that more workers are available for the 
private sector. To achieve this goal, Finland focused on making the 
delivery of government programs more efficient by using more 
electronic transactions. 

Another reason for electronic tax administration was to provide equal 
access to government services. Finnish law requires all e-services to 
be accessible to all Finnish citizens. With a significant segment of 
its population living in remote regions, according to officials, 
improving e-government provides more equal access to government 
services. To encourage equal access and use of the Internet for 
delivering services, Finland established standard speeds of Internet 
access in July 2009.[Footnote 30] 

What Are the Known Results and Effects of Electronic Tax 
Administration? 

Finland's tax system is viewed positively by taxpayers and industry 
groups. Members of several industry and taxpayer groups told us that 
Finland has a simple, stable tax system, which makes compliance 
relatively easy. They also commented that the Tax Card and preprepared 
annual return system work well and are easy to use. As a result, few 
individuals use a tax advisor to help prepare and file the annual 
income tax return. We were told that individuals using a tax advisor 
have complex tax issues, such as from owning a businesses or having 
complex investments. 

Electronic tax administration has advantages for the government and 
Finnish taxpayers. According to tax officials, cost savings result 
from spending less time to prepare and process tax returns. These 
officials said that electronic tax administration has helped to reduce 
their full-time-equivalent positions over 11 percent from 2003 to 
2009. Further, the tax withholding system results in a small amount of 
individual income tax withheld that needs to be refunded after final 
returns are filed. For tax year 2007, 8 percent of the tax withheld 
was refunded to taxpayers as compared to 26 percent refunded in the 
United States. 

Finland's culture of cooperation and the resulting cooperative 
arrangements between government, banks, businesses, and taxpayers have 
led to acceptance of the new Tax Card Online service. According to 
public interest and trade groups in Finland, the Finnish society has a 
great deal of confidence in the banking system and its secure access. 
This confidence influenced the decision to place the Tax Card online 
service on bank Web sites. With taxpayers having regular access to a 
banking Web site,[Footnote 31] the banks offer a channel for 
delivering government services, according to government officials. 
Public interest and trade groups agreed, noting that the banking 
industry's willingness to support the Tax Card enhanced its 
development. Representatives of a Finnish banking trade group said 
that placing the Tax Card system on their Web sites helped banks. That 
is, the more time customers spend on banks' Web sites, the more 
opportunities the banks had to offer other services, helping to offset 
the cost of implementing the system. 

According to Finnish trade and public interest groups, Finland's 
cooperative culture also supports the preprepared individual income 
tax return system. For this system to work properly, business and 
other organizations must file accurate information returns within 1 
month after the end of the tax year. This short period for filing 
information returns creates some burden. The burden includes costs to 
purchase and install special software for collecting the information 
as well as preparing and filing the returns. According to a 
professional accounting organization in Finland, buying the yearly 
software updates can be expensive. Any update has to be available well 
before the start of the tax year so that transactions can be correctly 
recorded at the start of the year and not revised at the end of the 
year. 

What Are the Similarities to and Differences from the U.S. System? 

In contrast to Finland's self-described "simple" system, the U.S. tax 
system is complex and changing annually. Regarding withholding 
estimation, Finland's Tax Card system provides taxpayers an online 
return system for regularly updating the tax amount withheld. For 
employees in the United States, the IRS's Web site offers a 
withholding calculator to help employees determine whether to contact 
their employer about revising their tax withholding. Finland's system 
prepares a notice to the employer that can be sent through the mail or 
delivered in person, whereas in the United States the taxpayers must 
file a form with the employer on the amount to be withheld based on 
the taxpayers' estimation. 

In the United States, individual income tax returns are completed by 
taxpayers--not IRS--using information returns mailed to their homes 
and their own records.[Footnote 32] Taxpayers are to file an accurate 
income tax return by its due date. Unlike in Finland, U.S. individual 
taxpayers heavily rely on tax advisors and tax software to prepare 
their annual return. In the United States, about 90 percent of 
individual income tax returns are prepared by paid preparers or by the 
taxpayer using commercial software.

Appendix IV: EU's Multilateral Treaty Information Exchange on Interest 
Payments to Member Nations' Citizens: 

Overview of the EU Directive: 

In June 2003, the European Union (EU) adopted the Savings Taxation 
Directive to encourage tax compliance by exchanging information and in 
some cases using withholding. The directive is a multilateral 
agreement that establishes uniform procedures and definitions for 
exchanging information and facilitating the resolution of common 
technical problems. Under the directive, the 27 EU members[Footnote 
33] and 10 dependent and associated territories agreed to participate 
in the directive.[Footnote 34] With this information, tax authorities 
in the citizen's nation are able to verify whether the citizen 
properly reported and paid tax on the interest income. Each of the 27 
member nations has a separate tax system, and varies in the tax rates 
imposed on personal income, as shown in table 3. 

Table 3: Range of Highest Personal Income Tax Rate for EU Countries, 
2010: 

Highest personal income tax rate: 50 percent or greater; 
Number of EU countries: 6. 

Highest personal income tax rate: 40 percent or greater and less than 
50 percent; 
Number of EU countries: 10. 

Highest personal income tax rate: 30 percent or greater and less than 
40 percent; 
Number of EU countries: 4. 

Highest personal income tax rate: 20 percent or greater and less than 
30 percent; 
Number of EU countries: 2. 

Highest personal income tax rate: 10 percent or greater and less than 
20 percent; 
Number of EU countries: 5.

[End of table] 

The highest personal income tax rates range from 10 percent in 
Bulgaria to over 56 percent in Sweden. This range of tax rates is an 
important reason for the need for the exchange of information on 
income. Residents in higher-tax countries could be motivated to move 
capital outside of the country of residence to potentially avoid 
reporting income earned on investments of the capital. 

How Does the EU Savings Taxation Directive Strive to Encourage Tax 
Compliance? 

The directive provided a basic framework for information exchanges, 
defining essential terms such as beneficial owner of the asset paying 
interest, identity and residence of the owner, paying agents,[Footnote 
35] interest payments, and information to be reported, and 
establishing automatic information exchange among members. The 
directive also states that five other nonmember nations agreed to 
information exchange upon request for information defined under the 
Savings Taxation Directive.[Footnote 36] 

During a transition period from 2005 through 2011, Belgium, 
Luxembourg, and Austria as well as the five nonmember nations, and six 
associated territories, agreed to a withholding tax.[Footnote 37] 
Under these agreements, a withholding tax was to be remitted at the 
rate of 15 percent during the first 3 years, 20 percent for the next 3 
years, and 35 percent thereafter. The directive authorizes the 
withholding nations to retain 25 percent of the tax collected and 
transfer 75 percent of the revenue to the account owner's home nation. 
The withholding nations may develop procedures so that the owners can 
request that no tax be withheld. These procedures generally require 
that the owner provide identification information to the paying agent 
or to the account owner's home nation. 

The directive also requires the account owner's home nation to ensure 
that the withholding does not result in double taxation. The home 
nation is to grant a tax credit equal to the amount of tax paid to the 
nation in which the account is located. If the tax paid exceeds the 
amount due to the home nation, the home nation is to refund to the 
account owner the excess amount that was withheld. 

The role of the EU Commission is to coordinate among the participants 
in the directive. The commission sets up and maintains contact points 
for communications among members. All information to be exchanged must 
be submitted no later than June 13 each year to the commission and 
follow the standardized Organisation for Economic Co-operation and 
Development (OECD) format. The information exchange is completely 
electronic and automatic. All information is sent and received through 
a secure network that only member countries can access. As of 2010, 
all member countries are using this standard format except for 
Switzerland which is working with the EU on plans for information 
exchange. The commission is to keep the format updated and 
periodically review compliance by member countries. 

The commission is to gather statistics to measure overall performance 
and success of the directive. Member countries have agreed to provide 
the commission with the statistics necessary to gauge performance. 
Every 2 years the commission hosts a conference to receive feedback 
from member nations on its performance and to gauge the directive's 
success. Additionally, every 3 years the commission reports to the 
European Parliament and Commission of the European Communities. The 
first report on the operation of the directive was issued in September 
2008.[Footnote 38] 

Why Does the EU Use the Multilateral Treaty Information Exchange? 

The EU adopted the Savings Taxation Directive to encourage tax 
compliance by exchanging information and using withholding. Using a 
multilateral agreement provided a way to uniformly establish 
procedures and definitions for exchanging information as well as for 
resolving any common technical problems to information exchange across 
the entire EU. 

What Are the Known Results and Effects of the Information Exchange on 
Savings? 

The September 2008 report to the EU described the status of the 
directive. The report found that 25 members started applying the rules 
as required in July 2005. In 2006, the first full year in which data 
were available, 17 members provided information to the exchange. 
Bulgaria and Romania began implementation in January 2007. The report 
concluded that the largest economies and financial centers reported 
the highest amounts of interest paid to other EU citizens. For 2006, 
Germany, France, Ireland, and the Netherlands accounted for over 98 
percent of the dollar value of interest paid by all EU nations to 
citizens of other EU countries.[Footnote 39] 

The report concluded that data limitations created major difficulties 
for evaluating the effectiveness of the directive. The EU did not have 
information on withholding results or time-series information from 
before the directive began. Without this information, the EU had no 
benchmark to measure the effect of the changes. 

According to EU officials, the most common administrative difficulties 
have been information-technology system problems. Some members have 
not had the data formatted correctly, which caused problems when other 
member nations tried to access the data. For example, how member 
countries format their mailing address has led to data access 
problems. To overcome this problem, most member countries insert the 
taxpayer's mailing address in the free text field, but this makes the 
data difficult to efficiently analyze by other nations. Another 
example has been accessing data from languages that have special 
diacritical marks or characters. When information exchanged included 
these special characters, an error was created during the data 
importation process. The directive has suffered from other 
implementation problems, as follows. 

Investor behavior. EU staff said the commission tried to measure 
changes in the different types of investments before and after 
implementation of the directive. The commission had difficulty in 
identifying the overall effect the directive has had on individual 
investment choices because the data used are generally limited to 
interest-bearing investments. On the basis of decreases in some 
investor's total interest savings, the report noted that investors 
appeared to change their investments before implementation to 
investments that were not covered by the directive. 

Withholding. The effectiveness of the withholding system under the 
Saving Tax Directive is unclear. The report found that the 14 
countries and dependent and associated territories applying the 
withholding provisions in 2006 shared €559.12 million (US$738 million) 
withheld on income earned in their nation with the account owner's 
home nation.[Footnote 40] Some articles have commented that given the 
low withholding rates in the early years, taxpayers with higher tax 
rates in their home nation may have chosen not to report the income. 

Definitions. The EU identified problems with the definition of terms, 
making uniform application of the directive difficult. First, the 
commission's report raised questions about consistency of coverage of 
payments made from life insurance contracts where investments were 
made in securities or funds. Second, confusion existed over whether 
some paying agents were covered by EU rules on investment managers or 
by the definition established under the directive for noncovered 
paying agents.[Footnote 41] Third, identifying the account owners was 
another problem. 

In general, the EU report suggests that improved monitoring and follow-
up by the home nation can help locate paying agents in third counties 
and ensure accurate information on the citizen who owns the account. 
The EU is considering several solutions such as enforcing existing 
customer due diligence rules that are to be used by domestic paying 
agents, who would transmit interest payments to the owners. These 
rules require that the paying agents must know who they are paying and 
should not facilitate transactions to mask the owner(s) and avoid 
taxes or other legal requirements. 

Nevertheless, EU officials stated that the quality of data has 
improved over the years. The EU officials have worked with EU member 
nations to resolve specific data issues, which has contributed to the 
effective use of the information exchanged under the directive. 

What Are the Similarities to and Differences from the U.S. System for 
Sharing Tax Information? 

Generally, unlike the EU multilateral directive, the United States 
establishes bilateral information-sharing agreements. Those agreements 
allow for automatic information exchange, but definitions of terms, 
technical standards, and other matters are not worked out and adopted 
multilaterally. Resolution of some of those issues may be facilitated 
by the United States' participation in the Convention on Multilateral 
Administrative Assistance in Tax Matters, which includes exchange of 
information agreement provisions and has been ratified by 15 nations 
and the United States.[Footnote 42]

Appendix V: The UK Uses Information Reporting and Withholding So Most 
Wage Earners Do Not Need to File a Tax Return: 

Overview of the UK Tax System: 

The United Kingdom's (UK) main sources of tax revenue are income tax, 
national insurance contributions, value added tax, and corporate tax. 
Her Majesty's Revenue and Customs (HMRC) also administers taxes 
assessed for capital gains, inheritance, various stamp duties, 
insurance premium tax, petroleum revenue, and excise duties.[Footnote 
43] The income tax system--where the tax year runs from April 6 
through April 5--taxes individuals on their income from various 
sources, for example, employment earnings, self-employment earnings, 
and property income. 

Taxable individuals under 65 years of age receive a tax-free personal 
allowance (£6,475, or US$10,410 for the 2010-11 tax year).[Footnote 
44] If their total income is below the allowance amount, no tax is 
payable. The three main individual income tax rates for income above 
the personal allowance are 20 percent (£0-£37,400 or up to US$60,132), 
40 percent (£37,401-£150,000 or up to US$241,170), and 50 percent 
(over £150,000 or over US$241,170).[Footnote 45] HMRC uses 3 payment 
systems to collect income tax from individual taxpayers, depending on 
the type of income and whether the individual is employed, self-
employed, or retired.[Footnote 46] 

* Pay As You Earn (PAYE) is used to withhold tax on wages and salaries 
paid to individuals by employers. Employers are required to notify 
HMRC every time an employee starts or stops working for them. Then, 
HMRC determines a tax withholding code for each individual and 
employers use the tax codes, in conjunction with tax tables, to 
calculate the amount of tax to be deducted. 

* Self-assessment tax returns are used by some employees with higher 
rates of income or complicated tax affairs and by self-employed 
individuals with different kinds of business income. 

* At-source collection is when the tax, such as on interest and 
dividend income, is withheld at source when the income is paid. For 
example, tax is deducted from bank interest as it is credited to an 
individual. 

According to HMRC officials, the majority (68 percent) of taxpayers 
pay their tax solely through the PAYE system without having to submit 
a return to HMRC. Other actions have helped remove a large number of 
taxpayers from submitting a return. For example, the UK requires that 
tax on some income paid to individuals (such as bank interest) be 
withheld at a 20 percent rate and remitted to HMRC by the payer, and 
capital gains income up to the first £10,100 (US$16,239) is exempted 
from tax. 

The UK also is working towards burden reduction for the average 
taxpayer by simplifying the tax return. For example, according to HMRC 
officials, information that is not necessary has been removed from the 
return to reduce the return filing burden, and those taxpayers who are 
required to file a return find it straight-forward. 

How Do Information Reporting and Withholding Facilitate Tax Reporting 
and Risk Assessment? 

HMRC uses data from information reporting and withholding under the 
PAYE system to simplify the reporting of tax liability on income tax 
returns for individuals. PAYE adjusts income tax withheld so that the 
individual's tax liability is generally met by the end of the tax year. 

Information reporting helps HMRC and the individual taxpayer determine 
the total income tax liability, according to HMRC officials. 
Information returns are to report tax-related transactions by the 
taxpayer. They are to be supplied by banks and local governments to 
the taxpayer and HMRC at the end of the tax year. For example, banks 
are to provide interest payment information. Over 400 local government 
organizations are to report information on payments made to small 
businesses. Local government as both an employer and contractor must 
report information on payments made to others. 

The information provided by employers enables HMRC to update the 
employee's tax record and issue a tax code to the new employer to 
start the withholding against employee earnings. HMRC calculates the 
PAYE code using information about the previous year's income or other 
employment in the current tax year.[Footnote 47] Employers are to 
match the PAYE code to a tax table, which shows how much tax to 
withhold each pay period. The employer has to remit the withheld tax 
to HMRC on a monthly or quarterly basis to fulfill the taxpayer's tax 
liability. HMRC annually reviews taxpayer records and issues updated 
PAYE codes before the start of the tax year for employers to operate 
at the start of the tax year. The individual will receive a notice 
showing how the tax code has been calculated. To maintain taxpayer 
confidentiality, the employer will only receive the tax code itself. 

HMRC can refund income tax overpayments or collect underpayments for 
previous tax years through adjustments to the PAYE code. HMRC reported 
in 2010 that around 5 million individuals overpaid or underpaid these 
taxes. HMRC officials said that they use information returns to help 
determine these adjustments under PAYE.[Footnote 48] In lieu of having 
their PAYE codes adjusted, taxpayers may receive a onetime refund of 
the overpayment or pay the underpaid amount in one lump sum. Taxes 
owed usually are collected through code adjustments as long as the 
taxpayer stays within the PAYE system. 

HMRC also uses information reporting and withholding to assess the 
compliance risks on filed returns. In assessing compliance risks, HMRC 
is attempting to identify underpaid and overpaid tax. The majority of 
the information for risk assessment is collected centrally from 
information returns, tax withholdings, filed tax returns, and public 
sources. This information is mined for risks by special risk-
assessment teams. According to HMRC officials, the outcomes of such 
mining are to be used to verify tax compliance. If low compliance is 
found, risk specialists are to develop programs to increase compliance. 

The data mining uses electronic warehouse "Data Marts" that HMRC has 
had for about 10 years.[Footnote 49] They have been configured with 
subsets of data and have been supplemented by sophisticated analysis 
tools for doing risk assessments. For example, an analyst can create 
reports to assess the risk for all self-assessment income tax returns 
where the legal expense is above a specified amount. HMRC officials 
told us that Data Marts had recently been revamped and a strategic 
capability was added that links related information such as a business 
that files a corporate tax return for its business profits, pays value 
added tax, and has directors who submit self-assessment returns. 

According to HMRC officials, the use of Data Marts combined with their 
more recent Strategic Risking Capability has allowed them to assess 
risks at the national and regional levels. HMRC officials said that 
they have moved towards national risk assessments because risk has not 
proven to be geographically based at regional levels. HMRC officials 
noted that while a return is being assessed for one type of risk, 
another type of risk can be found. HMRC is attempting to uncover 
emerging compliance risks by combining and reviewing data from the 
various sources in the Data Marts and elsewhere. 

The risk assessment process has two steps, resulting in identifying 
tax returns for examination. The first step is to identify tax returns 
that have an inherent risk because of the taxpayers' size, complexity 
of the tax return, and past tendency for noncompliance. For example, 
returns filed by high-wealth individuals are viewed as risky returns 
that are sent to a related specialty office. The second step assesses 
risk on returns that are not sent to a specialty office. HMRC 
officials said that a relatively large proportion of the risk-
assessment effort focuses on the self-employed, who are seen as having 
the greatest risk for tax noncompliance since they usually are not 
under the PAYE system (unless they have some wage income) and instead 
are to file a self-assessment return. HMRC has separate risk-
assessment approaches, depending on the type of individual taxpayer, 
as discussed below. 

* For individuals under the PAYE system, HMRC's computers capture most 
of the necessary data and the system carries out routine checks to 
verify data and link it to the taxpayer record. A risk to the PAYE 
system arises when employees receive benefits from their employers 
that are not provided to HMRC at the time it determines the annual tax 
code. Employer benefits may include a car, health insurance, or 
professional association fees that employers report on information 
returns after the tax year and that may be subject to income tax. If 
these benefits received are not included in the tax code then an 
underpayment of tax is likely to arise. The unpaid tax can be 
recovered by an annual reconciliation or when the employee reports the 
benefits on the employee's self-assessment tax return. 

* Individuals not under the PAYE system are required to file a self- 
assessment tax return. To assess risk, HMRC checks some self-
assessment tax returns for consistency by comparing them to returns 
from previous years, focusing on small businesses. For example, if the 
legal expense jumped from £5,000 to £100,000 (US$8,039 to US$160,780) 
over 2 years, HMRC may decide to review the reason. HMRC permits any 
self-employed small business with gross receipts of less than £68,000 
(US$109,330) to file a simple three-line tax return to report business 
income, expenses, and profit. HMRC officials said that the threshold 
allows over 85 percent of all self-employed businesses to file 
simplified returns with less burden. 

Why Did the UK Use Information Reporting and Withholding for Tax 
Reporting and Risk Assessment? 

According to HMRC officials, their policy is to collect as much data 
as possible up front through information returns, and correct the 
amounts of tax due with the PAYE system, facilitating the payment of 
tax liabilities. Since information is shared with HMRC, taxpayers are 
likely to voluntarily comply if they have to file a tax return. 
Further, data from information reporting and withholding are to help 
simplify or eliminate tax reporting at the end of a tax year. 
According to HMRC officials, the PAYE system makes it unnecessary for 
most wage earners to file an annual self-assessment tax return. 

HMRC conducts risk assessments because staff cannot check every tax 
return in depth due to the large number of taxpayers and the need to 
lower the costs of administering the tax system. Data from information 
reporting and withholding provide consistent sources for doing risk 
assessments. 

What Are the Known Results and Effects from Using Information 
Reporting and Withholding to Facilitate Tax Reporting and Risk 
Assessment? 

HMRC officials said the income tax system has been simplified because 
most individual taxpayers fall under the PAYE system, which generally 
relieves them of the burden of filing a tax return. Even so, some 
implementation problems have occurred. The House of Commons identified 
problems with an upgrade to the PAYE information system in 2009-10. 
[Footnote 50] The upgrade was to combine information on individuals' 
employment and pension income into a single record to support more 
accurate tax withholding codes and reduce the likelihood of over-and 
underpayments of tax. However, software problems delayed processing 
2008-09 PAYE returns for a year. In addition, data-quality problems 
from the upgraded PAYE system for 2010-11 generated about 13 million 
more annual tax coding notices than HMRC had anticipated and some were 
incorrect or duplicates. With these problems, of the 45 million PAYE 
records to be reconciled, 10 million cases needed to be reconciled 
manually. 

The House of Commons reported a backlog of cases before the PAYE 
system was upgraded. Limitations of the previous PAYE system and 
increasingly complex working patterns have made it difficult to 
reconcile discrepancies without manual intervention. As of March 2010, 
a backlog of PAYE cases affected an estimated 15 million taxpayers 
from 2007-08 and earlier; the backlog included an estimated £1.4 
billion (US$2.25 billion) of tax underpaid and £3 billion (US$4.82 
billion) of tax overpaid. 

HMRC has reported that risk assessment has provided three benefits: 
(1) improved examination decisions to ensure that they are necessary 
and reduce the burden on compliant taxpayers; (2) tailored 
examinations to the risk in question; and (3) deterred taxpayers from 
concealing income. HMRC's risk-assessment approach has increasingly 
focused on providing help and support to individuals and smaller 
businesses to voluntarily comply up front. To minimize the need for 
examinations, HMRC aims to help larger businesses achieve greater and 
earlier certainty on their tax liabilities. HMRC's sharper focus on 
risk assessment means that businesses with reliable track records of 
managing their own tax risks and being open in their dealings with 
HMRC benefit from fewer HMRC examinations while those with the highest 
risks can expect a more robust challenge from dedicated teams of 
specialists. 

What Are the Similarities to and Differences from the U.S. System? 

The UK and United States both have individual income tax returns and 
use information reporting and tax withholding to help ensure the 
correct tax is reported and paid. However, differences exist between 
the countries' systems. 

* The United States has six tax rates that differ among five filing 
statuses for individuals (i.e., single, married, married filing 
separately, surviving spouse, or head of household) and covering all 
types of taxable income. In general, the UK system has three tax 
rates, one tax status (individuals), and a different tax return 
depending on the taxable income (e.g., self-employed or employed 
individuals). 

* U.S. income tax withholding applies to wages paid but not interest 
and dividend income as it does in the UK. 

* U.S. wage earners, rather than the Internal Revenue Service, are 
responsible for informing employers of how much income tax to 
withhold, if any, and must annually self-assess and file their tax 
returns, unlike most UK wage earners. 

Another major difference is that the United States automatically 
matches data from information returns and the withholding system to 
data from the income tax return to identify individuals who 
underreported income or failed to file required returns. Matching is 
done using a unique identifier taxpayer identification number (TIN). 
HMRC officials told us that they have no automated document-matching 
process and the UK does not use TINs as a universal identifier, which 
is needed for wide-scale document matching. The closest form of unique 
identifier in the UK is the national insurance number. HMRC officials 
said they are barred from using the national insurance number for 
widespread document matching. Instead, HMRC officials said that they 
may do limited manual document matching in risk assessments and 
compliance checks. For example, HMRC manually matches some taxpayer 
data--such as name, address, date of birth--from bank records to data 
on tax returns.

Appendix VI: Australia Uses a Compliance Program for High-Net-Wealth 
Individuals: 

Overview of the Australian Tax System: 

Australia has a federal system of government with revenue collected at 
the federal, state, and local levels. For 2009-2010, about 92 percent 
of federal revenue was collected from taxes rather than nontax 
sources, like fees. The principal source of federal revenue for 
Australia is the income tax, which accounted for about 71 percent. 
Australia's state and local governments rely on grants from the 
national government and have limited powers to raise taxes. The states 
receive significant financial support from the federal government. In 
2009-10, total payments to the states were 28 percent of all federal 
expenditures. 

Individuals accounted for about 65 percent of the 2009-2010 income tax 
revenue. The system is progressive with tax rates up to 45 percent for 
taxable income in excess of A$180,000 (US$161,622). In 2007-2008, a 
small proportion of Australian taxpayers paid a large proportion of 
Australian taxes, as shown in figure 1.

What Is the Australian High Net Wealth Individuals Program? 

The Australian High Net Wealth Individuals (HNWI) program focuses on 
the characteristics of wealthy taxpayers that affect their tax 
compliance. According to the Australian Taxation Office (ATO), in the 
mid 1990s, it was perceived as enforcing strict sanctions on the 
average taxpayers but not the wealthy. ATO found that high-wealth 
taxpayers, those with a net worth of more than A$30 million (US$20.9 
million), tend to have complex business arrangements, which made it 
difficult for ATO to identify and assure compliance. ATO concluded 
that the wealthy required a different tax administration approach. 

ATO set up a special task force to improve its understanding of 
wealthy taxpayers, identify their tax planning techniques, and improve 
voluntary compliance. Initially, the program focused on the tax return 
filed by a wealthy individual. Due to some wealthy taxpayers' 
aggressive tax planning, which ATO defines as investment schemes and 
legal structures that do not comply with the law, ATO quickly realized 
that it could not reach its goals for voluntary compliance for this 
group by examining taxpayers as individual entities. 

To tackle the problem, ATO began to view wealthy taxpayers as part of 
a group of related business and other entities. Focusing on control 
over related entities rather than on just individual tax obligations 
provided a different understanding of wealthy individuals' compliance 
issues. To address the special needs of the wealthy, ATO developed 
publications that included a separate high-wealth income tax return 
form, a questionnaire on the wealthy as an entity and a tax guide, 
Wealthy and wise--A tax guide for Australia's wealthiest people. 

Why Australia Developed the High Net Wealth Program: 

According to ATO, a number of factors led to the HNWI program. First, 
ATO was dealing with a perceived public image that it showed 
preference to the wealthy while enforcing strict sanctions on average 
taxpayers during the 1990s. Second, ATO was perceived as losing 
revenue from noncompliant taxpayers. Third, high-wealth individuals 
used special techniques to create and preserve their income and wealth 
through a "business life cycle." The cycle includes creating, 
maintaining, and passing on wealth through complex tax shelters. For 
example, businesses owned or controlled by wealthy individuals are 
more likely to have more diverse businesses arrangements, which tend 
to spread wealth across a group of companies and trusts. Each of these 
groups controlled by wealthy individuals was classified as a separate 
taxpayer entity, which made understanding the tax implications of 
these networks of entities difficult for the ATO. 

The HNWI approach followed ATO's general compliance model. The model's 
premise is that tax administrators can influence tax compliance 
behavior through their responses and interventions. Since taxpayers 
have different attitudes on compliance, ATO used varied responses and 
interventions tailored to promote voluntary tax compliance across 
different taxpayer groups. 

The first part of the standard model is to understand five factors 
that influence taxpayer compliance. The factors are Business, 
Industry, Social, Economic, and Psychological. For example, the 
Business factor included the size, location, nature, and capital 
structure of the business as well as its financial performance--all of 
which help ATO understand why compliance or noncompliance occurs. 
[Footnote 51] 

The second part of the model involves taxpayers' attitudes on 
compliance. It refers to one of four attitudes that a taxpayer may 
adopt when interacting with tax regulatory authorities. These 
attitudes are: 

* willing to do the right thing, 

* try to do the right thing, 

* do not want to comply, and: 

* decided not to comply. 

The third part of the model aligns four compliance strategies with the 
four taxpayer attitudes on compliance[Footnote 52] and refers to the 
degree of ATO enforcement under the concept of responsive regulation. 
ATO prefers to simplify the tax system and promote voluntary 
compliance through self-regulation. If the taxpayer tries to comply, 
ATO should respond by helping the taxpayer be compliant. If the 
taxpayer is not motivated to comply, ATO should respond to the level 
of noncompliance with some degree of enforcement, ending with harsh 
sanctions for the truly noncompliant. 

ATO created a High Wealth Individual (HWI) taskforce to assess wealthy 
individuals on their probability of compliance and place them into one 
of four broad risk categories using its Risk Differentiation Framework 
(RDF). RDF is similar to the compliance model in that it is to assess 
the tax risk and determine the intensity of the response for those 
with high net wealth, ranging from minimizing burden on compliant 
wealthy taxpayers to aggressively pursuing the noncompliant. The four 
broad categories of the RDF are as follows: 

* Higher Risk Taxpayers--ATO performs continuous risk reviews of them 
with the focus on enforcement. 

* Medium Risk Taxpayers--ATO periodically reviews certain transactions 
from them or where there is a declining trend in effective tax 
performance with a focus on enforcement. 

* Key Taxpayers--ATO continuously monitors them with the focus on 
service. 

* Low Risk Taxpayers--ATO periodically monitors them with the focus on 
service. 

What Are the Known Results and Effects of the Australian High Net 
Wealth Program? 

The HNWI program has produced financial benefits since its 
establishment in 1996. ATO 2008 data showed that the program had 
collected A$1.9 billion (US$1.67 billion) in additional revenue and 
reduced revenue losses by A$1.75 billion (US$1.5 billion) through 
compliance activities focused on highly wealthy individuals and their 
associated entities. ATO's approach also has been adopted by other tax 
administrators. According to a 2009 Organisation for Economic Co- 
operation and Development (OECD) study, nine other OECD countries, 
including the United States, had adopted some aspect of Australia's 
HNWI program.[Footnote 53] 

Similarities to and Differences from the U.S. Tax System: 

Like ATO, the IRS is taking a close look at high-income and high-
wealth individuals and their related entities. In 2009, IRS formed the 
Global High Wealth Industry (GHWI) program to take a holistic approach 
to high-wealth individuals. IRS consulted with the ATO to discuss 
ATO's approach to the high-wealth population as well as its 
operational best practices. As of February 2011, GHW field groups had 
a number of high-wealth individuals and several of their related 
entities under examination. 

One difference is that Australia has a separate income tax return for 
high-wealth taxpayers to report information on assets owned or 
controlled by HNWIs. In contrast, the United States has no separate 
tax return for high-wealth individuals and generally does not seek 
asset information from individuals. According to IRS officials, the 
IRS traditionally scores the risk of individual tax returns based on 
individual reporting characteristics rather than a network of related 
entities.[Footnote 54] However, IRS has been examining how to do risk 
assessments of networks through its GHWI program since 2009. Another 
difference is that ATO requires HNWIs to report their business 
networks, and IRS currently does not.

Appendix VII: Hong Kong Uses Semiannual Payments Instead of Periodic 
Employer Withholding for the Salaries Tax: 

Overview of the Hong Kong Tax System: 

Hong Kong's Inland Revenue Department (IRD) assesses and collects the 
"earnings and profits tax," which includes a Profits Tax,[Footnote 55] 
Salaries Tax, and Property Tax. IRD also assesses and collects certain 
"duties and fees" including a stamp duty, business registration fees, 
betting duty, and estate duty. Hong Kong only taxes income from 
sources within Hong Kong. Principle revenue sources for tax year 2009-
10 are shown in figure 2. 

Figure 2: Hong Kong Tax Year 2009 to 2010 Revenue Sources: 

[Refer to PDF for image: pie-chart] 

Profits Tax: 42.8%; 
Stamp Duty: 23.7%; 
Salaries Tax: 23.0%; 
Other: 10.5%. 

Source: GAO analysis of Hong Kong data. 

[End of figure] 

According to a Hong Kong tax expert, Hong Kong created the Salaries 
Tax at the start of World War II without using periodic tax 
withholding. The lack of withholding was not then, and is not now, 
considered to be a significant problem.[Footnote 56] The Salaries Tax 
is paid by about 40 percent of the estimated 3.4 million wage earners 
in Hong Kong, while the 60 percent are exempt from the Salaries Tax. 

Taxpayers whose salary income is lower than their entitlement to 
deductions (i.e., basic allowance, child allowance, dependent parent, 
etc.) are exempt from paying Salaries Tax and neither they nor IRD 
prepare a tax return for this income. However, exempt taxpayers may 
receive a tax return from IRD once every few years to verify their tax-
exempt status. If these exempt taxpayers receive a tax return from 
IRD, they are required to complete and submit it within 1 month. 
[Footnote 57] 

The Salaries Tax rates are fairly low, according to Hong Kong tax 
experts. The Salaries Tax has progressive rates starting at 2 percent 
of the adjusted salary earned and may not exceed the standard rate of 
15 percent. In comparison, the highest personal income tax rates in 
the EU range from about 10 percent to over 56 percent as described in 
appendix IV.[Footnote 58] 

How Does Hong Kong Collect Salaries Tax? 

Hong Kong does not use periodic tax withholding (e.g., biweekly or 
monthly) by employers to collect Salaries Taxes. Rather, IRD collects 
the Salaries Tax through two payments from taxpayers for a tax year, 
which runs from April 1 to March 31. The first payment is due in 
January (9 months into the tax year) and is to be 75 percent of the 
estimated tax for the whole year. The second payment is for the 
remaining 25 percent, which is due 3 months later in April--
immediately after the end of the tax year. 

In May, IRD is to mail the tax return to the individual for the just- 
completed tax year based on information provided by employers and 
other sources. Information reporting to IRD has four parts. First, 
employers must report when each employee is hired and the expected 
annual salary amount. Second, at the end of the tax year, employers 
must report the salary paid to each employee. Third, the employers 
must report when the employee ceases employment. Fourth, employers 
must report and temporarily withhold payments to an employee they know 
intends to leave Hong Kong. If the employer fails to comply with these 
requirements without a reasonable excuse, penalties may be imposed. 

Individuals have 1 month to file the return.[Footnote 59] For those 
who elect to file their returns electronically, IRD will prefill the 
return based on information provided in their past returns and by 
their employers. They have a month and a half to review the prepared 
tax return, make any revisions such as changes to deductions, and file 
it with IRD. 

IRD reviews the filed tax returns to determine the final Salaries Tax. 
IRD electronically screens all returns to check for consistency 
between the information provided by the employer and taxpayer. 
Assessments will normally be made based on the higher amount reported, 
and taxpayers have the right to object within 1 month. IRD also can 
cross-check reported salary amounts with salary deductions claimed by 
businesses on Profit Tax returns, which should normally be supported 
by information returns on employee salary amounts. If the final 
Salaries Tax for the tax year turns out to be higher than the 
estimated tax assessment, taxpayers are to pay the additional tax 
along with the first payment of the estimated tax for the next tax 
year during the following January, as shown in figure 3.

Why Does Hong Kong Collect Salaries Tax through Two Yearly Payments? 

Several factors contribute to Hong Kong's collection of the Salaries 
Tax through two payments for a tax year without resorting to periodic 
withholding by employers. 

* The tax only affects about 40 percent of the wage earners who have 
the highest salaries and uses relatively low tax rates, making it more 
likely that the taxpayers will have the funds necessary to make the 
two payments when due. 

* The simplicity of Hong Kong's tax system, according to Hong Kong tax 
experts, makes it easier to compute tax liability and to manage the 
payments. 

* IRD uses a combination of controls to assure that tax payments are 
made, according to a senior IRD official. In addition to information 
reporting, island geography contributes to the controls. Hong Kong 
entry/departure points are limited and tax evaders are likely to be 
identified. Hong Kong government can detain a tax evader from leaving 
or entering Hong Kong until the tax is paid. IRD has varied processes 
to trace the assets of delinquent taxpayers as part of collecting any 
unpaid tax. 

* Culture encourages taxpayers to pay their taxes. Hong Kong experts 
said taxpayers fear a loss of face if they are recognized as 
noncompliant, which could reflect negatively on the family. A Hong 
Kong official told us that residents try to avoid being taken to court. 

An expert on public opinion in Hong Kong told us that this cultural 
attitude generates high tax morale. The expert told us that Hong Kong 
residents have high regard for Hong Kong's government as being 
"cleanly" run and as putting tax revenues to good use. IRD is viewed 
as having fair and equal treatment of all taxpayers. 

What Are the Known Results and Effects from Collecting the Salaries 
Tax through Two Yearly Payments? 

A senior official of Hong Kong's IRD believes that the Salaries Tax 
collection system leads to high tax compliance. Low tax rates in 
concert with a simple tax system that offers generous deductions and 
effective enforcement mean that taxpayers are fairly compliant, 
according to the Hong Kong official. It also means that few taxpayers 
use a tax preparer because the tax forms are very straightforward and 
the tax system is "stable." 

The official also said that taxpayers comply because the cost of 
noncompliance is high. If a taxpayer does not pay by the due date, the 
costs include paying the tax liability, interest surcharges on the 
debt, and legal costs. Further, submitting an incorrect tax return 
without reasonable excuse may carry a fine of HK$10,000 (US$1,283) 
plus three times the amount of tax underpaid and imprisonment. 

What Are the Similarities to and Differences from the U.S. System? 

Unlike Hong Kong's twice-a-year payments for the Salaries Tax, the 
U.S. income tax on wages relies on periodic tax withholding. IRS 
provides guidance (e.g., Publication 15) on how and when employers 
should withhold income tax (e.g., every other week) and deposit the 
withheld income taxes (e.g., monthly). Further, the U.S. individual 
tax rates are higher and the system is more complex. These tax rates 
begin at 10 percent and progress to 35 percent. Further, the United 
States taxes many forms of income beyond salary income on the 
individual tax return.

Appendix VIII: Overview of Tax Systems for Five Nations: 

Nations have many choices on how to structure their tax systems across 
the federal, as well as state and local, government levels. The 
proportion of revenue collected at each governmental level can widely 
vary. Finland, New Zealand, and the United Kingdom (UK) have a unitary 
system in which government, including tax administration, is generally 
centralized at the national level with limited state and local 
government. For example, in New Zealand, the national government 
assessed about 90 percent of all the revenue collected across the 
nation. In contrast, the United States has a federal system in which 
the national level shares governmental authority with state and local 
governments. In the United States about half of all tax revenue is 
collected by the national government and about half is collected by 
the 50 states and tens of thousands of local governments. 

The revenue data in table 4 below were provided by each nation and 
compiled by the Organisation for Economic Co-operation and Development 
(OECD) for consistent presentation.[Footnote 60] These data cover all 
taxes in each nation including federal and state/local levels. Using 
these data, we computed the percent that each type of tax represents 
of the nation's total revenue. OECD provided the following definition 
for each of the major categories of tax in the table: 

* Taxes are compulsory unrequited payments to general government and 
are not for benefits provided by government to taxpayers in proportion 
to their payments. Governments include national governments and 
agencies whose operations are under their effective control, state and 
local governments and their administrations, certain social security 
schemes and autonomous governmental entities, excluding public 
enterprises. 

* Taxes on income, profits, and capital gains cover taxes levied on 
the net income or profits (i.e., gross income minus allowable tax 
deductions) of individuals and businesses (including corporations). 
Also covered are taxes levied on the capital gains of individuals and 
enterprises, and gains from gambling. 

* Social security contributions are classified as all compulsory 
payments that confer an entitlement to receive a (contingent) future 
social benefit. Such payments are usually earmarked to finance social 
benefits and are often paid to institutions of general government that 
provide such benefits. These social security benefits would include 
unemployment insurance benefits and supplements, accident, injury and 
sickness benefits, old-age, disability and survivors' pensions, family 
allowances, reimbursements for medical and hospital expenses or 
provision of hospital or medical services. Contributions may be levied 
on both employees and employers. 

* Taxes on payroll and workforce cover taxes paid by employers, 
employees, or the self-employed either as a proportion of payroll or 
as a fixed amount per person, and which do not confer entitlement to 
social benefits. 

* Taxes on property, goods, and services cover recurrent and 
nonrecurrent taxes on the use, ownership, or transfer of property. 
These include taxes on immovable property or net wealth, taxes on the 
change of ownership of property through inheritance or gift, and taxes 
on financial and capital transactions. Taxes on goods and services 
include all taxes and duties levied on the production, sale, and lease 
of goods or services. This category covers multistage cumulative 
taxes; general sales taxes, value added taxes, excise taxes, or taxes 
levied on imports and exports of goods. 

Table 4 shows that the largest source of revenue for 4 of 5 countries 
is the tax on individuals' and corporations' income, profits, and 
capital gains. Also, the tax paid by individuals is a larger 
percentage of revenue than the corporation tax in each country. The 
tax on property, goods, and services is the next most important tax 
except in the UK where the income tax is the second largest source. A 
large component of the taxes on property, goods, and services is the 
value added tax and sales tax. In Australia, New Zealand, the UK, and 
Finland, value added tax and sales tax ranged from 25 percent to 31 
percent of the taxes collected in the nation. The United States does 
not have a value added tax, but sales taxes alone totaled about 14 
percent of all U.S. revenue.

[19] PAYE is an amount an employer deducts from an employee's salary 
and wages to satisfy income tax and other obligations. Company Tax is 
income taxed at the company rate. Schedular Payments are paid by self- 
employed contractors and companies often in the agricultural, 
horticultural, and viticulture industries. The business or person 
paying the contractor is required to deduct a pre-determined 
percentage of income and remit this to IRD. 

[20] KiwiSaver is a voluntary, work-based retirement savings 
initiative. 

[21] The Family tax credit provides payments to families with 
dependent children age 18 or younger earning less than specified 
minimum income levels and varying depending on the number of children. 
The In-work tax credit provides payments for parents based on the 
number of hours of weekly paid employment. The Minimum family tax 
credit provides payments to parents with dependent children based on 
the number of hours of weekly paid employment. The Parental tax credit 
provides payments for a newborn baby for the first 8 weeks and is an 
alternative to Paid Parental Leave, which is administered on behalf of 
the Department of Labour. 

[22] Accommodation supplements assist families with rent, board, or 
costs of owning a home. Childcare subsidies assist families with 
childcare costs for children under 14. Temporary additional support is 
a weekly payment to help families meet essential living costs. 

[23] Generally, IRD makes WFF tax credit payments (weekly, biweekly or 
annually). MSD may make the Family tax credit payment instead of IRD, 
such as when recipients are receiving welfare benefits. MSD makes its 
WFF tax credit payments mainly through the benefit system.

[26] A similar approach is now required under the recently enacted 
GPRA Modernization Act of 2010, Pub. L. No. 111-352, 124 Stat. 3866 
(2011). The act requires OMB, in coordination with agencies, to 
develop federal government priority goals including a limited number 
of crosscutting goals, and assess the contributions made toward those 
goals by various agencies and federal activities--including spending 
programs and tax expenditures. 

[27] All returns are final at October 31. The taxpayer must appeal 
before the end of the 5th year following the assessment year. 

[28] Finland has about 500,000 businesses, of which about half were 
solely owned by individual taxpayers as of 2010. 

[29] Based on 2011 estimates, the population median age in Finland is 
42.5 years as compared to the U.S. median age of 36.9 years. 

[30] A Decree of the Ministry of Transport and Communications 
specifies the minimum rate of functional Internet access as a 
universal service and requires a functional rate for downstream 
traffic as 1 megabit per second. 

[31] About three-quarters of Finnish citizens use an Internet bank. 

[32] If the taxpayer fails to file a return and enough information 
returns reporting income have been filed, the IRS can create a return, 
based on that information, and mails it to the taxpayer for acceptance 
or adjustment. IRS prepares these returns under a compliance program 
and the taxpayer may be assessed penalties. 

[33] EU members include Austria, Belgium, Bulgaria, Cyprus, the Czech 
Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, 
Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, 
Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, and the 
United Kingdom. 

[34] In addition to EU members, certain dependent and associated 
territories of member countries have agreed to participate with the 
directive. These territories include the Cayman Islands, Anguilla, 
Turks and Caicos Islands, Montserrat, Aruba, Jersey, Guernsey, the 
Isle of Man, the British Virgin Islands, and the Netherlands Antilles. 
Four of the territories (Anguilla, Aruba, Cayman Islands, and 
Montserrat) have agreed to information exchange. As of October 2010, 
the Netherlands Antilles became an independent nation. 

[35] Paying agents are defined as intermediaries responsible for 
paying interest income received from debtors to owners of the debt. 
For example, a bank can be considered a paying agent. 

[36] These nations are the Swiss Confederation, the Principality of 
Liechtenstein, the Republic of San Marino, the Principality of Monaco, 
and the Principality of Andorra. The information upon request exchange 
generally requires a more detailed justification for the information 
needed by the requesting tax authority. 

[37] Six dependent and associated territories (Turks and Caicos 
Islands, Jersey, Guernsey, the Isle of Man, the British Virgin 
Islands, and the Netherlands Antilles) have agreed to the withholding 
provisions.

Working Document, Presenting an economic evaluation of the effects of 
the Council Directive 2003/48/EC on the basis of the available data;

[39] The United Kingdom reported information from July 1, 2005, to 
April 5, 2006. 

[40] The amount corresponds with 75 percent of the total withholding 
tax or about €745.47 million (about US$984 million). The British 
Virgin Islands and the Netherlands Antilles did not share withholding. 

[41] An example would be Liechtenstein foundations where payments made 
are covered by the directive, but in practice the payments rarely were 
reported as interest payments. 

[42] The convention is in force among Azerbaijan, Belgium, Denmark, 
Finland, France, Iceland, Italy, the Netherlands, Norway, Poland, 
Slovenia, Spain, Sweden, Ukraine, and the United Kingdom. 

[43] Excise duties are levied on items such as alcohol products, 
tobacco products, and mineral oils. 

[44] After April 2011, the personal allowance will be reduced for 
those with income above £100,000 (US$160,780). 

[45] The UK has additional tax rates for interest savings and dividend 
income. The rates for both savings and dividend income start at 10 
percent, and higher rates may apply depending on the amount of the 
related income. 

[46] Retired individuals receiving a pension will pay income tax 
through the Pay As You Earn (PAYE) or self-assessment systems. 

[47] The employees can also ask HMRC to include other income such as 
some self-employment, rental, or savings income in determining their 
PAYE code. 

[48] HMRC officials said that only HMRC can adjust PAYE codes because 
only HMRC knows a taxpayer's total income. A taxpayer can provide HMRC 
with additional information that can be used to adjust the PAYE code.
