Subject: Activities of the Treasury Inspector General for Tax 
Administration: 

The Department of the Treasury Inspector General for Tax Administration 
(TIGTA) audits and investigates the Internal Revenue Service's (IRS) 
operations to (1) promote economy and efficiency and detect and prevent 
fraud and abuse and (2) recommend actions for improvement. TIGTA was 
established by the Internal Revenue Service Restructuring and Reform 
Act of 1998[Footnote 1] (IRS Reform Act), which amended the Inspector 
General Act of 1978[Footnote 2] (IG Act), to include an independent 
inspector general (IG) to provide oversight of IRS's activities, 
programs, and offices. 

This report responds to your request that we review the activities of 
TIGTA. As discussed with your staff, we are providing information 
regarding (1) TIGTA's budget and staffing levels; (2) TIGTA's audit and 
investigative coverage of IRS, including oversight of IRS's offices and 
identified weaknesses in IRS's operations, and audit coverage of 
specific requirements of the IRS Reform Act; (3) TIGTA's audit and 
investigative accomplishments; (4) the quality assurance program, 
including the results of peer reviews; and (5) the audit follow-up 
process to track IRS's implementation of TIGTA's audit recommendations. 

Results in Brief: 

Over the 5-year period of fiscal years 2000 through 2004, TIGTA's 
budget authority increased by 14 percent while staff levels decreased 
by 6 percent. In fiscal year 2004, TIGTA had budget authority of about 
$130 million and realized authorized full-time equivalent (FTE) staff 
of 877. In relation to IRS's total federal funds, the budget authority 
for TIGTA's oversight has steadily declined but is comparable to such 
ratios for other IG offices. 

During fiscal year 2004, TIGTA provided audit coverage of IRS through 
an organizational structure that mirrors IRS's organizational structure 
and through audit plans that include coverage of IRS's business units, 
management challenges, and congressionally mandated work. TIGTA's 
audits provided coverage of the IRS management challenges identified by 
TIGTA, the high-risk areas designated by us, and mandatory coverage 
required by the IRS Reform Act. Investigative coverage is provided 
through TIGTA's investigative mission of addressing employees' 
integrity, external attempts to corrupt tax administration, and 
employee and infrastructure security. 

As a result of its audit and investigative coverage, TIGTA reported 
that it issued 942 audit reports, addressed 39,611 complaints and 
allegations, and closed 22,350 investigations over the 5-year period of 
fiscal years 2000 through 2004. TIGTA claimed financial accomplishments 
resulting from these audits and investigations of over $16.3 billion, 
and identified additional potential financial impacts on tax 
administration of over $50 billion. 

TIGTA's external peer reviews and internal quality reviews have 
concluded that TIGTA's quality assurance program provides reasonable 
assurance that audit reports meet applicable standards. The program 
includes internal quality reviews of individual audits, internal 
quality inspections of the Office of Audit, and an external quality 
peer review of the Office of Audit every 3 years in compliance with 
government auditing standards.[Footnote 3] 

IRS tracks corrective actions on audit recommendations using the 
Department of the Treasury's Joint Audit Management Enterprise System 
(JAMES). The system includes audit recommendations from TIGTA, the 
Department of the Treasury Office of Inspector General, and us. IRS 
management is responsible for ensuring that corrective actions are 
taken on audit recommendations that address IRS. For fiscal years 2000 
through 2004, JAMES reported that as of May 2005, about 83 percent of 
all audit recommendations were implemented. 

Scope and Methodology: 

We obtained the actual budget authority and the staffing levels at 
TIGTA,[Footnote 4] and the total federal funds and FTEs at 
IRS,[Footnote 5] for fiscal years 2000 through 2004, as reported in the 
Budget of the United States Government. We used this information to 
identify trends over this period and to compare TIGTA's resources with 
overall IRS resources. In addition, we compared the ratio of IG budget 
authority with agency budgetary resources[Footnote 6] in fiscal year 
2004 for all IG offices for which an IG is appointed by the President 
and confirmed by the Senate. For fiscal year 2004 agency budgetary 
resources, we used information from the Statement of Budgetary 
Resources for each agency reported in the Fiscal Year 2006 Budget of 
the United States Government.[Footnote 7] We did not audit or otherwise 
verify the budget amounts. 

To analyze TIGTA's audit coverage of IRS, we compared the 
organizational structures of TIGTA and IRS to analyze coverage of IRS's 
offices and missions, obtained copies of completed audits, and reviewed 
all audit reports issued by TIGTA during fiscal year 2004. We compared 
the subjects and contents of these audit reports with weaknesses at IRS 
previously identified by TIGTA and us to determine the extent to which 
the known weaknesses were being covered through TIGTA's audits. In 
addition, we compared the audit reports with TIGTA's statutorily 
mandated coverage of IRS's administration of specific provisions of the 
IRS Reform Act. To illustrate the investigative coverage of IRS, we 
obtained the number of investigative cases that addressed the mission 
areas of TIGTA's Office of Investigations during fiscal year 2004. 

We identified the audit and investigative accomplishments reported by 
TIGTA in semiannual reports to the Congress for fiscal years 2000 
through 2004, and obtained examples of individual reports to 
illustrate. We did not audit or otherwise verify the dollar amount of 
financial accomplishments reported by TIGTA. 

Regarding quality control, we interviewed TIGTA staff and obtained 
documentation of TIGTA's quality control process, including the reports 
on quality control, internal quality inspections, and external peer 
review reports of TIGTA's audit operations. We also interviewed TIGTA 
staff regarding the tracking of audit recommendations and obtained 
JAMES documentation for audit follow-up, including information about 
the percentage of recommendations implemented by IRS. 

We performed our audit from March 2005 through August 2005, in 
accordance with U.S. generally accepted government auditing standards. 
We requested comments on a draft of this report from the Treasury 
Inspector General for Tax Administration or his designee. We received 
written comments from the Treasury Inspector General for Tax 
Administration, which we have reprinted in enclosure IV. We also 
received several oral comments offering technical suggestions, which we 
have incorporated as appropriate. 

Background: 

IRS administers America's tax laws and collects the revenues that fund 
most government operations and public services. Each year IRS employees 
make millions of contacts with American taxpayers and businesses. To 
accomplish its mission, IRS focuses its efforts on achieving three key 
goals: (1) improving taxpayer service; (2) enhancing enforcement of the 
tax law; and (3) modernizing IRS through people, processes, and 
technology. For the fiscal year 2004 filing season, IRS reported that 
it collected over $2 trillion, processed over 131 million individual 
returns, and issued approximately 100 million refunds totaling about 
$208 billion. 

TIGTA is responsible for the independent oversight of IRS at the 
Department of the Treasury. Formed in January 1999 as a result of the 
IRS Reform Act, TIGTA is an oversight organization within the 
Department of the Treasury in addition to, and independent of, the 
Department of the Treasury Office of Inspector General, which was 
established by the IG Act Amendments of 1988.[Footnote 8] Both IGs 
report directly to the Secretary of the Treasury; however, TIGTA 
provides oversight of IRS, and the Treasury IG provides oversight of 
the remaining offices at the Department of the Treasury. 

Prior to the IRS Reform Act, IRS oversight was provided by the Treasury 
IG and the IRS Office of Chief Inspector, also known as the Inspection 
Service. Established on October 1, 1951, the Inspection Service was 
responsible for carrying out internal audits and investigations to (1) 
promote the economic, efficient, and effective administration of the 
nation's tax laws; (2) detect and deter fraud and abuse in IRS's 
programs and operations; and (3) protect IRS from external attempts to 
corrupt or threaten its employees. The Chief Inspector reported to 
IRS's Commissioner and Deputy Commissioner and provided information to 
the Treasury IG, who included the results of Inspection Service 
activities in the Treasury IG's semiannual reports to the Congress. 

In 1998 the Senate Committee on Finance concluded that the Office of 
Chief Inspector lacked sufficient autonomy from IRS to independently 
provide monitoring and oversight activities.[Footnote 9] In addition, 
the committee believed that the relationship between the Treasury IG 
and the Inspection Service did not foster the appropriate oversight of 
IRS. Consequently, to improve the quality and the credibility of IRS's 
oversight, TIGTA was established within the Department of the Treasury 
to provide independent audits and investigations of IRS. 

In addition to the authorities and responsibilities granted under the 
IG Act, the IRS Reform Act gives TIGTA the statutory authority to allow 
staff to carry firearms, execute and serve search and arrest warrants, 
serve subpoenas and summonses, make arrests, and seize property. The 
IRS Reform Act also makes taxpayer returns and return information 
available for inspection by TIGTA. TIGTA reports to and operates under 
the general supervision of the Secretary of the Treasury; however, 
neither the Secretary nor any other officer of the Treasury Department 
can prevent or prohibit TIGTA from initiating, carrying out, or 
completing any audit or investigation, or from issuing a subpoena 
during the course of any audit or investigation. In addition, TIGTA is 
required to report to the Attorney General whenever there are 
reasonable grounds to believe that there has been a violation of 
federal criminal law. 

Consistent with the IG Act and the IRS Reform Act, TIGTA conducts 
audits and investigations of IRS's programs and operations to promote 
the economic, efficient, and effective administration of the nation's 
tax laws and to detect and deter fraud and abuse in IRS's programs and 
operations. TIGTA's primary functional offices are the Office of Audit, 
the Office of Investigations, the Office of Information Technology, the 
Office of Management Services, and the Office of the Chief Counsel. As 
required by the IG Act, TIGTA reports its activities and the results of 
audit and investigative efforts in semiannual reports to the Congress 
for the periods ending March 31 and September 30 each year. Also, TIGTA 
presents specific information in these semiannual reports about IRS's 
compliance with provisions of the IRS Reform Act. 

TIGTA Budgets and Staffing: 

The IRS Reform Act provided that all but 300 of IRS's Inspection 
Service FTEs for fiscal year 1998 be transferred to TIGTA. The IRS 
Commissioner was allowed to retain up to 300 FTEs to staff an internal 
audit function. In addition, 21 FTEs previously transferred from the 
Inspection Service to the Treasury IG for oversight of IRS pursuant to 
a 1990 memorandum of understanding (MOU) were transferred to the newly 
formed TIGTA. As a result, TIGTA realized 932 FTEs and had budget 
authority of about $114 million in fiscal year 2000, its first year of 
operations. In fiscal year 2004, TIGTA had budget authority of $130 
million and realized 877 authorized FTEs. As of September 30, 2004, 
TIGTA had 874 staff on board with 317 in the Office of Audit; 432 in 
the Office of Investigations; 81 in the Office of Information 
Technology; 23 in the Office of Management Services, including the IG; 
and 21 in the Office of Chief Counsel. 

From fiscal year 2000 through fiscal year 2004, TIGTA's budget 
authority increased by 14 percent, from $114 million to $130 million, 
while TIGTA's FTEs decreased by 6 percent, from 932 to 877. TIGTA's 
increased budget authority occurred mostly in the second year of 
operations because of expenses related to establishing an independent 
office and the effects of full costing of federal retirements. Since 
fiscal year 2001, TIGTA has operated in a relatively unchanged budget 
environment while absorbing increases in costs that are largely beyond 
TIGTA's control, accompanied by a corresponding reduction in FTEs. For 
a comparison, during fiscal years 2000 through 2004, overall IRS's 
total federal funds increased by 52 percent and FTEs increased by 1 
percent. Therefore, even though they have both increased in recent 
years, TIGTA's budget authority as a percentage of IRS's total federal 
funds decreased from 0.30 percent to 0.23 percent. (See table 1.)

through 2004:

[End of table] 

The comparison of TIGTA's budget authority with IRS's total federal 
funds represents the amount provided for IG oversight as it relates to 
the amount of budgetary resources received by the agency that it 
oversees. When this comparison is made for the other IG offices in 
which the IG is appointed by the President and confirmed by the Senate, 
the percentages vary depending on the size of the federal agencies, 
their missions, and the oversight issues emphasized by each IG office. 
Such a comparison for fiscal year 2004 budgets indicates that the ratio 
of TIGTA's budget authority to IRS's total federal funds was within the 
range of these percentages for other IGs and their agencies. (See enc. 
I.) The comparison of IGs' budget authorities and agencies' budgetary 
resources ranged from 0.004 percent to 1.03 percent, whereby TIGTA's 
percentage of IRS resources was at 0.23 percent, which ranks sixth of 
28 agencies. This comparison at IRS does not include the implications 
of IRS's main role as the nation's tax collector and the amount of 
federal revenue collected by the IRS. 

Audit Coverage of IRS: 

In fiscal year 2004, TIGTA issued 189 audit reports, which provided 
audit coverage of IRS's operating divisions and other units (see enc. 
II), as well as the high-risk areas identified by us, management 
challenges identified by TIGTA, and audits of IRS's activities mandated 
by the IRS Reform Act. This is accomplished through TIGTA's 
organizational structure, which has four business units reporting to 
the Deputy IG for Audit that are aligned with IRS's operating divisions 
and other units, and provide audits of identified risks and 
congressionally mandated IRS requirements. (See fig. 1.) 

Figure 1: TIGTA Organization Chart: 

For example, in fiscal year 2004, TIGTA's Wage and Investment Income 
business unit issued 40 audit reports that addressed the IRS Wage and 
Investment Division's mission to serve tax filers with wage and 
investment income and to help taxpayers understand the tax laws. The 
work of this division includes IRS's enforcement of the tax laws, the 
processing of taxpayers' returns, and the administration of the Earned 
Income Tax Credit and Advanced Earned Income Tax Credit while 
minimizing the burden on taxpayers and protecting their privacy. 

Also, in fiscal year 2004, TIGTA's Small Business and Corporate 
Programs business unit issued 37 audit reports to cover IRS's Small 
Business and Self-Employed Division, which serves self-employed 
individuals; individual filers with income from rents, royalties, 
pensions, annuities, partnerships, estates, and trusts; and small 
businesses with assets of up to $10 million. These audits also included 
coverage of IRS's Large and Mid-Size Business Division, which serves 
businesses with assets of more than $10 million. During fiscal year 
2004, TIGTA's audits concentrated on assessing IRS's efforts to provide 
quality service while helping taxpayers understand the tax laws, 
processing the tax returns, and enforcing compliance with the tax laws. 

TIGTA's Headquarters Operations and Exempt Organizations business unit 
issued 82 audit reports in fiscal year 2004 to provide coverage of 
IRS's Tax-Exempt and Government Entities Division, which serves a wide 
range of customers, including small local community organizations, 
municipalities, major universities, pension funds, state governments, 
Indian tribal governments, and tax-exempt bond issuers. 

These audits also provide coverage of IRS's Financial Management and 
Operations, IRS's activities in compliance with the Government 
Performance and Results Act of 1993,[Footnote 10] the Criminal 
Investigation function, and agencywide shared services. 

TIGTA's Information Systems business unit issued 30 audit reports to 
cover IRS efforts to modernize its core business systems and to provide 
high-quality, efficient, and responsible information services for its 
operating divisions. In addition, through these audits, TIGTA oversees 
the security of information systems, the buildings that house the 
systems, and the people who operate them, and assesses IRS's efforts to 
manage risks and vulnerabilities throughout its technology 
modernization projects. 

Audit Coverage of Risks and Mandates: 

While TIGTA is organized to provide audits that address IRS's operating 
divisions and other units, emphasis is also placed on high-risk areas 
identified by us, IRS's management challenges identified by TIGTA, and 
mandatory coverage required by the IRS Reform Act. Since 1990, we have 
periodically reported on government operations that we have designated 
as high risk because of their greater vulnerabilities to fraud, waste, 
abuse, and mismanagement. We also identify high-risk areas to focus on 
the need for broad-based transformations to address major challenges to 
economy, efficiency, or effectiveness. 

In January 2003 we identified 25 high-risk areas across government and 
added a 26TH high-risk area in July 2003. These areas included IRS's 
multibillion-dollar Business Systems Modernization program, financial 
management, collection of unpaid taxes, and earned income tax credit 
noncompliance. In January 2005 we combined the financial management 
area with the systems modernization area into a category titled 
"Business Systems Modernization," and combined the earned income credit 
noncompliance with the collection of unpaid taxes into a category 
titled "Enforcement of Tax Laws.": 

The management challenges identified by TIGTA at the beginning of 
fiscal year 2004 include the high-risk areas identified by us; 
therefore, TIGTA'a audits of management challenges provide coverage of 
our identified high-risk areas at IRS.[Footnote 11] (See enc. III.) The 
identification of management challenges by the IGs began in 1997 when 
the IGs were asked by congressional leaders to identify the 10 most 
serious management problems in their respective agencies. This request 
began a yearly process that continues as a result of the Reports 
Consolidation Act of 2000.[Footnote 12] This act called for executive 
agencies, including IRS, to include their IGs' lists of significant 
management challenges in their annual performance and accountability 
reports to the President, the Office of Management and Budget (OMB), 
and the Congress. 

Efforts to modernize IRS's systems, mandated by the IRS Reform Act, 
began in fiscal year 1999. IRS expects that it will take 10 to 15 years 
at a cost of $7 billion to $10 billion. We have recognized the 
modernization of IRS's systems as a high-risk area, and TIGTA has 
identified this as a management challenge that will require attention 
for years to come. TIGTA has also recognized that the integration of 
IRS's financial management and performance are management challenges at 
IRS by citing the weaknesses we reported in our audits of IRS's 
financial statements. These challenges include serious deficiencies in 
financial systems, including control weaknesses and system deficiencies 
affecting financial reporting, unpaid tax assessments, tax revenue and 
refunds, and computer security. In fiscal year 2004, TIGTA completed 15 
audits that addressed IRS's systems modernization and 13 audits that 
addressed IRS's financial management and performance. 

IRS's administration of tax compliance initiatives and taxpayer 
protection and rights are also designated by TIGTA as management 
challenges. Both of these challenges include the collection of taxes, 
which is also a GAO high-risk area. In addition, TIGTA has recognized 
improper payments at IRS as a management challenge that includes 
taxpayers' noncompliance with the earned income tax credit. To provide 
audit coverage of these areas in fiscal year 2004, TIGTA completed 29 
audits of tax compliance initiatives along with 17 audits of taxpayers' 
protection and rights, which included the collection of unpaid taxes, 
and 5 audits that addressed erroneous and improper payments, which 
included taxpayers' noncompliance with the earned income tax credit. 

TIGTA's fiscal year 2004 audits also covered the statutorily mandated 
audits specified in the IRS Reform Act, which requires TIGTA to review 
IRS's actions taken to improve service to taxpayers. TIGTA's audit 
reports covered the following areas: 

* restrictions on the use of enforcement statistics to evaluate IRS 
employees, 

* any termination or mitigation under section 1203 of the IRS Reform 
Act,[Footnote 13] 

* information regarding the improper denial of requests for information 
from IRS, 

* restrictions on directly contacting taxpayers who have indicated they 
prefer their representatives be contacted, 

* procedures on the filing of a notice of a lien, 

* procedures for seizure of property, 

* certification that the Treasury Secretary complied with certain 
disclosures, 

* extensions of the statute of limitations for the assessment and 
collection of taxes, 

* adequacy and security of IRS technology, 

* restrictions on the designation of taxpayers as illegal tax 
protesters, and: 

* actions with respect to violations of the fair-debt-collection 
provisions. 

To satisfy additional statutory provisions, TIGTA reported in each 
fiscal year 2004 semiannual report the number of taxpayer complaints 
during the period and the number of employee misconduct and taxpayer 
abuse allegations received by IRS or the IG during the period from 
taxpayers, IRS employees, and other sources. In addition, the 
semiannual reports included a required summary of the status of such 
complaints and allegations as well as their disposition, including any 
action by the Department of Justice and any moneys paid as a 
settlement. 

Investigative Coverage: 

As was the case with the audit function, the IRS Reform Act also 
transferred the statutory law enforcement authority of the former IRS 
Inspection Service to TIGTA and its Office of Investigations. TIGTA has 
responsibility for enforcing criminal law related to internal revenue 
and focuses investigations on three main areas of concern: (1) 
allegations of criminal violations and serious administrative 
misconduct by IRS employees; (2) external attempts to corrupt tax 
administration; and (3) issues of employee infrastructure and security. 
(See fig. 2.) The Office of Investigations' authority includes 
executing and serving search and arrest warrants, serving subpoenas and 
summonses, making arrests without warrant for any offense against the 
United States related to internal revenue laws, and seizing property 
subject to foreclosure under IRS laws. 

Figure 2: TIGTA's Office of Investigations Closed Investigations by 
Investigative Area Reported by TIGTA in Fiscal Year 2004: 

[See PDF for image] 

[End of figure] 

The investigative responsibilities of TIGTA's Office of Investigations 
are coordinated with the IRS Criminal Investigation office through an 
MOU between TIGTA and the Chief of IRS Criminal Investigation signed in 
August 2000. The MOU specifies that IRS Criminal Investigation will 
investigate violations of the Internal Revenue Code's substantive 
criminal tax provisions, such as attempted evasion, failure to file or 
pay, the subscription of false documents, and corrupt endeavors to 
obstruct or impede the administration of the tax code. TIGTA has 
responsibility to protect IRS against external attempts to corrupt or 
threaten IRS employees, including investigations of allegations of IRS 
employee conduct violations and other allegations regarding employee 
integrity. 

During fiscal year 2004, TIGTA reported that it closed 3,900 
investigative cases.[Footnote 14] Of these, 1,695 investigations, or 43 
percent, addressed employee integrity cases, such as misconduct, 
extortion, theft, taxpayer abuses, false statements, and financial and 
contractor fraud. For example, because of these investigations, two IRS 
employees were indicted for diverting tax refunds to their own 
accounts, an employee pleaded guilty to filing fabricated income tax 
returns to obtain tax refund payments, and an employee pleaded guilty 
to stealing checks payable to IRS and altering them for personal use. 

TIGTA reported that 32 percent of closed investigations during fiscal 
year 2004, or 1,231 investigations with final referrals, addressed 
external attempts to corrupt or interfere with the administration of 
internal revenue laws. These external attempts to corrupt or interfere 
include bribes offered by taxpayers to compromise IRS employees, the 
manipulation of IRS's systems and programs, the use of fraudulent IRS 
documentation, and impersonation of IRS officials. Specifically, TIGTA 
reported that the Office of Investigations conducted 56 investigations 
into bribery allegations involving taxpayers, 280 investigations of 
attempts to manipulate IRS's systems and operations, and 895 
investigations into nontax fraud and other related activities. To 
illustrate, as a result of TIGTA's investigations, an individual was 
sentenced for mail fraud because this individual directed clients to 
deposit funds for tax purposes into a fund used for the individual's 
personal purposes. In addition, individuals were sentenced for bribing 
IRS employees and for impersonating IRS employees. 

The remaining 25 percent of closed investigations, or 974 investigative 
cases with final referrals reported by TIGTA, addressed employee and 
infrastructure security to ensure IRS's ability to collect taxes. 
Specifically, this includes activities by the Office of Investigations 
to identify threats against IRS personnel and facilities and to notify 
IRS management of the potential for harm. In addition, TIGTA also 
investigates threats and assaults directed at facilities and employees, 
which include arresting individuals who direct threatening letters and 
statements to IRS employees. Consequently, as reported, TIGTA issued 64 
advisories notifying IRS management of potential threats and completed 
910 investigations of threats and assaults directed at IRS facilities 
and employees. 

TIGTA's Accomplishments: 

Statutory IGs, including TIGTA, are required by the IG Act to report 
specific financial accomplishments in their semiannual reports provided 
for the Congress. As required, TIGTA's semiannual reports for fiscal 
years 2000 through 2004 included the number of audit reports issued and 
the questioned costs, unsupported costs, and funds to be put to better 
use identified by the audits. As defined by the IG Act, questioned 
costs include either alleged violations of laws, regulations, 
contracts, grants, or agreements; costs not supported by adequate 
documentation; or the expenditure of funds for an intended purpose that 
was unnecessary or unreasonable. In addition, unsupported costs are 
defined as costs that do not have adequate documentation, and funds to 
be put to better use are inefficiencies identified by the IG in the use 
of agency funds. For the 5-year period, TIGTA issued 942 audit reports 
and reported $16.1 million in questioned costs, $3.1 million in 
unsupported costs, and $16.2 billion in funds to be put to better use. 

In an example of questioned costs, TIGTA's follow-up audit of controls 
over IRS's telecommunications costs found that about $2.2 million of 
questioned costs had been identified by IRS based on TIGTA's prior 
findings of ineffective controls. In an example of unsupported costs, 
TIGTA audited four invoices from the IRS business systems modernization 
contract and found approximately $9.5 million of these costs 
unsupported by documentation from the contractor. After TIGTA's audit 
report draft was issued, the contractor provided documentation to 
support all but approximately $52,000 of the $9.5 million originally 
questioned. In an example of funds to be put to better use, TIGTA 
recommended that IRS reduce the amount of underused office space, which 
could save about $84 million per year. 

In addition to the audit accomplishments, during the same 5-year 
period, TIGTA reported that 39,611 complaints and allegations were 
addressed and that 22,350 investigative cases were closed. This 
activity resulted in the reported recovery of about $17.5 million of 
embezzled or stolen funds and almost $80 million in court-ordered 
fines, penalties, and restitutions. In addition, reported nonmonetary 
investigative accomplishments included almost 10,000 criminal 
referrals--of which about 1,700 were accepted for prosecution by the 
Department of Justice or state or local authorities--and administrative 
dispositions on 3,805 investigations, which included removal, 
termination of employment or suspension, reduction in grade, written or 
oral reprimand, or resignation of the employee. The combined financial 
accomplishments from audits and investigations reported by TIGTA over 
the 5-year period totaled about $16.3 billion. 

In addition to the audit information required by the IG Act, TIGTA's 
Office of Audit has identified measures that demonstrate additional 
potential financial impact on tax administration. These accomplishments 
are intended to provide further insights into the value and potential 
impact of TIGTA's audits and include increases in the collection of 
additional taxes, improvements to revenue protection and taxpayer 
privacy, correction of inefficient uses of resources, needed 
protections of human and capital assets, and correction of problems 
with the reliability of management information. To illustrate, TIGTA 
estimated that by improving the controls to ensure that tax returns 
with potential transfer pricing[Footnote 15] issues are referred to 
international examiners for consideration, federal revenue could 
increase by approximately $32.3 million annually, provided that IRS has 
the additional resources to examine the returns. For the 5-year period 
we reviewed, TIGTA reported over $50 billion of these additional 
potential financial impacts. 

TIGTA Quality Assurance Program: 

TIGTA's quality assurance program includes a quality review of 
individual audit reports, internal quality inspections to monitor the 
quality of audits, and external quality peer reviews. Specifically, the 
IG Act requires federal IGs to follow Government Auditing Standards, 
which requires an appropriate internal quality control system and an 
external peer review every 3 years. These standards specify that 
quality control systems should include procedures for monitoring, on an 
ongoing basis, whether the policies and procedures related to the 
standards are suitably designed and are being effectively applied. 

To comply with the quality assurance standard, TIGTA's Office of 
Management and Policy uses a standardized checklist to review all draft 
audit reports prior to issuance. This review addresses audit scope, 
finding attributes, the sufficiency and relevancy of findings in 
comparison to the audit objectives, the adequacy of recommendations to 
address identified causes, audit sampling methodology, and quantifiable 
outcome measures. In addition, the review provides assurance of general 
compliance with professional auditing standards; conformance with TIGTA 
report format; clarity of information; and conformance with rules for 
grammar, punctuation, and style. 

TIGTA also performs quality assurance through internal quality 
inspections of each of its four business units once every 3 years. In 
these inspections, each business unit is assigned responsibility for 
conducting the inspection of another business unit and reporting to the 
Deputy IG for Audit on the results. The checklist used in this review 
includes steps derived from the quality assurance process of the 
President's Council on Integrity and Efficiency (PCIE)[Footnote 16] and 
guidance from Government Auditing Standards. The checklist has 
questions that address staff qualifications, independence, professional 
judgment, independent referencing, audit planning, sampling plans, 
supervision, evidence, work papers, internal controls, illegal acts, 
noncompliance, abuse, and reporting. 

Two internal inspections of TIGTA's business units have been completed, 
and two are planned for the audit activities covering fiscal years 2004 
and 2005. The reviews of the Headquarters Operations and Exempt 
Organizations unit and the Wage and Investment Income unit found that 
the audits conducted by these business units were completed in 
compliance with U.S. generally accepted government auditing standards. 
In addition, the reports concluded that audit staff generally complied 
with Office of Audit policies and procedures. The review did find 
instances in which the audit teams could more closely follow policies 
and procedures and reported TIGTA's planned actions to address the 
review's conclusions. 

TIGTA has obtained two external peer reviews from other IG offices 
since fiscal year 2000 and obtained an unqualified opinion in each 
review. These external quality control reviews provide TIGTA with an 
independent opinion on the quality control system, whether the system 
is in place and operating effectively, and whether the policies and 
applicable audit standards are being followed. The Transportation IG 
performed the most recent external peer review of TIGTA. The peer 
review report, dated January 22, 2004, concluded that the quality 
control system for the audit function had been designed in accordance 
with quality standards established by PCIE. The peer review report 
further states that TIGTA's quality control system provides reasonable 
assurance of material compliance with professional auditing standards 
in conducting its audits. The report also identifies opportunities for 
TIGTA to strengthen compliance with its quality control system for the 
conduct of audits. The peer review observations include aspects of 
continuing professional education, quality control, audit planning, 
evidence and work papers, the assessment of management controls, and 
audit reporting. 

Audit Follow-up: 

The Department of the Treasury tracks audit recommendations through the 
JAMES. JAMES includes all audit recommendations from TIGTA, the 
Treasury IG, and us on the basis of information provided by the 
auditors, and tracks the status of management's response and 
implementation. Treasury's process for tracking audit recommendations 
is consistent with OMB Circular No. A-50, Audit Follow Up, which states 
that audit follow-up on recommendations contained in audit reports is 
an integral part of good management and is a shared responsibility of 
agency management officials and auditors. In addition, each agency is 
required to establish a system to ensure the prompt and proper 
resolution and implementation of audit recommendations. 

The IG Act also requires that semiannual reports prepared by the IGs, 
including those of TIGTA, provide an identification of each significant 
recommendation described in previous semiannual reports for which 
corrective action has not been completed. In addition, Government 
Auditing Standards requires that audit plans include a consideration of 
the results of previous audits that could affect the current audit 
objectives and follow-up on known significant findings and 
recommendations. 

Under OMB Circular No. A-50, IRS management is responsible for 
completing plans for corrective actions to address audit 
recommendations and for ensuring that corrective action is taken in 
response to each audit report. Each TIGTA business unit has a staff 
member who is a JAMES user with the ability to query the system and 
provide feedback on the status of individual open or closed audit 
report recommendations. TIGTA's semiannual reports include the status 
of prior audit recommendations as required by the IG Act. Moreover, in 
compliance with government auditing standards, TIGTA officials stated 
that subsequent audits follow up on prior audit recommendations. During 
fiscal years 2000 through 2004, JAMES reported that of 2,912 corrective 
actions planned by IRS management to address TIGTA's audit 
recommendations, 2,625, or approximately 90 percent, were closed 
because IRS agreed to adopt the recommendations. Of these closed 
recommendations, JAMES reported that about 83 percent have been fully 
implemented.
