The Honorable Mark W. Everson:

Commissioner of Internal Revenue:

Subject: Management Report: Improvements Needed in IRS's Internal 
Controls:

Dear Mr. Everson:

In November 2004, we issued our report on the results of our audit of 
the Internal Revenue Service's (IRS) financial statements as of, and 
for the fiscal years ending, September 30, 2004 and 2003, and on the 
effectiveness of its internal controls as of September 30, 
2004.[Footnote 1] We also reported our conclusions on IRS's compliance 
with significant provisions of selected laws and regulations and on 
whether IRS's financial management systems substantially comply with 
requirements of the Federal Financial Management Improvement Act of 
1996. A separate report on the implementation status of recommendations 
from our prior IRS financial audits and related financial management 
reports, including this one, will be issued shortly.

The purpose of this report is to discuss issues identified during our 
fiscal year 2004 audit regarding internal controls that could be 
improved for which we do not currently have any recommendations 
outstanding. Although not all of these issues were discussed in our 
fiscal year 2004 audit report, they all warrant management's 
consideration. This report contains 30 recommendations that we are 
proposing IRS implement to improve its internal controls. We conducted 
our audit in accordance with U.S. generally accepted government 
auditing standards. We requested and received written comments on a 
draft of this report from the Commissioner of Internal Revenue.

Results in Brief:

During our fiscal year 2004 audit, we identified a number of internal 
control issues that adversely affected safeguarding of tax receipts and 
information, refunds to taxpayers, and lien resolutions. These issues 
concern (1) enforcement of IRS contractor background investigation 
policies, (2) omission of certain provisions related to contingency 
plans and taxpayer privacy in lockbox bank[Footnote 2] service 
contracts, (3) verification of lockbox bank deposits, (4) procedures 
for handling taxpayer receipts and information by couriers, (5) 
safeguarding sensitive systems and equipment in lockbox banks, (6) 
candling procedures, (7) monitoring and verifying recording and 
transmittal of taxpayer receipts and information, (8) controls over 
automated refund disbursements, (9) controls over authorization of 
manual refunds, and (10) resolution of liens with manually calculated 
interest or penalties.

Specifically, we found the following:

* At three IRS service centers we visited, some contractors who had not 
undergone background investigations and, in some cases, for whom 
background investigation requests had not been submitted, were granted 
staff-like access[Footnote 3] to restricted areas. In addition, at one 
service center we visited, the security office did not maintain files 
onsite that documented the status of background investigations for 
contractors with staff-like access to restricted areas.

* At three lockbox banks we visited, courier contingency plans did not 
cover all the contingencies specified in the "Lockbox Processing 
Guidelines" (LPG),[Footnote 4] and at another lockbox bank we visited, 
there was no courier contingency plan on file. In addition, at one of 
the lockbox banks we visited, the courier contract did not contain the 
language set out in the LPG related to privacy laws applicable to 
handling taxpayer information, and at three of the lockbox banks we 
visited, shredding contracts did not include required privacy 
provisions.

* At three lockbox banks we visited, we found that receipts for 
deposits delivered by courier services to depositories did not always 
indicate the time and date the deposits were received. We also found 
that two of these lockbox banks did not obtain deposit receipts from 
their couriers.

* For several courier services transporting taxpayer receipts and 
information, we found that procedures for handling taxpayer receipts 
and information at lockbox banks, service centers, or both were not 
always followed. This included (1) couriers not always transporting 
taxpayer receipts and information directly to their destination, (2) a 
courier vehicle containing a pickup that was left unattended, (3) 
transfer of taxpayer receipts and information from one courier vehicle 
to another, (4) solo couriers transporting taxpayer receipts and 
information, and (5) couriers not wearing required uniforms.

* At one lockbox bank we visited, the electrical and water shutoff 
valves were in an area where janitors kept their supplies and which 
they accessed daily, and the shutoff valves were not locked to prevent 
tampering. The security system control panel was located in the same 
area, and the keys to the panel were left on top of the panel. There 
were no surveillance cameras monitoring this room.

* At one lockbox bank we visited, a high-speed machine was used to 
extract checks from and candle[Footnote 5] envelopes, but no visual 
inspection or second candling was performed on envelopes opened by this 
machine. In addition, at one service center we visited, the candling 
tables in the final candling area did not provide sufficient light to 
enable personnel to ensure that all contents had been removed from 
envelopes.

* At the two IRS field offices we visited, we found that internal 
controls were not always properly followed to ensure that recording and 
transmittal of taxpayer receipts and information were adequately 
monitored and verified.

* At one of the service centers we visited to review refund procedures, 
IRS did not have adequate controls in place to prevent automated 
disbursements of improper refunds related to taxpayer accounts under 
investigation for potential unreported taxes.

* At the two service centers we visited to review refund procedures, 
controls over authorization of manual refunds were not effective.

* At the five lien units[Footnote 6] we visited, personnel were not 
properly verifying manual interest and penalty calculations for 
taxpayer accounts with liens with manually calculated interest or 
penalties.

The issues noted above increase the risk that (1) taxpayer receipts and 
information could be lost, stolen, misused, or destroyed; (2) improper 
refunds to taxpayers could be disbursed; and (3) liens could be 
released before taxpayers have paid the full amount of interest or 
penalties due.

At the end of our discussion of each of these issues in the following 
sections, we make recommendations for strengthening IRS's internal 
controls. These recommendations are intended to bring IRS into 
conformance with its own policies and with the internal control 
standards that all federal agencies are required to follow.[Footnote 7]

In its comments, IRS substantially agreed with our recommendations and 
described actions it had taken or planned to take to address the 
control weaknesses described in this report. At the end of our 
discussion of each of the issues in this report, we have summarized 
IRS's related comments and provided our evaluation.

Scope and Methodology:

As part of our audit of IRS's fiscal years 2004 and 2003 financial 
statements, we tested IRS's internal controls and its compliance with 
selected provisions of laws and regulations. We designed our audit 
procedures to test relevant controls, including those for proper 
authorization, execution, accounting, and reporting of transactions. 
This report addresses issues we observed during our fiscal year 2004 
audit. For issues related to safeguarding tax receipts, we visited four 
lockbox banks, four IRS service centers, and two IRS field offices; for 
issues related to tax refunds, we visited two IRS service centers; and 
for issues related to liens, we visited five IRS lien units.

Further details on our audit scope and methodology are included in our 
report on the results of our audits of IRS's fiscal years 2004 and 2003 
financial statements[Footnote 8] and are reproduced in enclosure II.

Enforcement of IRS Contractor Background Investigation Policies:

During our fiscal year 2004 audit, we found control deficiencies 
related to contractor employee background investigations at three of 
the four service centers we visited. Specifically, at one of these 
three service centers, IRS had not submitted paperwork for new 
clearances for 10 contractors with staff-like access even though their 
background investigations did not meet requirements that took effect in 
July 2000, including the requirement that such investigations be 
conducted by IRS's National Background Investigation Center. IRS did 
not submit paperwork for new clearances for these contractors until 
January 29, 2004--several years after they had been granted access. At 
another of these three service centers, one contractor who had not 
undergone the required background investigation--and for whom there was 
no evidence that a background investigation had been requested--had had 
staff-like access to restricted areas at the center for more than a 
year and a half. At the third of the three service centers, two 
contractors, one with access to restricted areas and the other with 
staff-like access to the service center, had not had the required 
background investigation. In addition, at one of the service centers we 
visited, the security office responsible for granting contractors 
unescorted access to restricted areas did not maintain files onsite 
that documented the status of background investigations for contractors 
with access to restricted areas.

IRS requires that all contractors have successfully completed a 
background investigation conducted by the National Background 
Investigation Center before being granted access to taxpayer receipts 
and information. Further, GAO's Standards for Internal Control in the 
Federal Government requires agencies to establish controls to safeguard 
vulnerable assets. Until IRS ensures that only contractors who have 
successfully met background investigation requirements have access to 
taxpayer receipts and sensitive information and that service center 
security offices can verify that these requirements have been met, the 
federal government will be unnecessarily exposed to the risk of loss, 
theft, or abuse of taxpayer receipts and information.

Recommendations:

We recommend that IRS:

* enforce its existing requirement that appropriate background 
investigations be completed for contractors before they are granted 
staff-like access to service centers and:

* require that background investigation results for contractors (or 
evidence thereof) be on file where necessary, including at contractor 
worksites and security offices responsible for controlling access to 
sites containing taxpayer receipts and information.

IRS Comments and Our Evaluation:

IRS agreed with our recommendation that background investigation 
results for contractors (or evidence thereof) be on file, where 
necessary, and stated that the Physical Security Program Office will 
work with the Business Operating Divisions and Procurement staff to 
determine if the interagency agreement with the Financial Management 
Service (FMS) should be modified to include a requirement for lockbox 
banks to maintain background investigation files. IRS stated that it 
has addressed the issues that gave rise to our recommendation that it 
enforce its existing requirement that appropriate background 
investigations be completed for contractors before they are granted 
staff-like access to service centers. IRS indicated that it has 
implemented steps to monitor and enforce existing requirements related 
to background checks for contractors. We will evaluate the 
effectiveness of IRS's efforts during our fiscal year 2005 financial 
audit.

Required Provisions in Lockbox Bank Service Contracts:

Lockbox banks enter into contracts with service providers for a variety 
of services, including transport of taxpayer receipts and information 
by couriers and shredding of taxpayer information prior to its 
disposal.

During our fiscal year 2004 audit, we found that the contract for 
courier services at one of the four lockbox banks lacked the language 
set out in the LPG that would acknowledge the legal restrictions on a 
courier's handling of taxpayer information. These legal restrictions 
are imposed by the Privacy Act of 1974[Footnote 9] and certain 
provisions of the Internal Revenue Code. We also found that contracts 
for shredding services at three of the four lockbox banks failed to 
include the mandatory provisions required for complying with federal 
law related to safeguarding taxpayer information. The LPG requires that 
the contracts include the safeguard provisions required by the Internal 
Revenue Code. Omission of privacy-related provisions from lockbox 
courier or shredding contracts increases the risk of unauthorized 
disclosure of taxpayer information.

In addition to the omission of contract provisions, we found problems 
in contract implementation during our fiscal year 2004 audit. We found 
that courier contract disaster contingency plans for three of the four 
lockbox banks we visited did not address all required contingencies. 
The other lockbox bank we visited did not have a courier disaster 
contingency plan on file. The LPG requires that before a contractor 
provides courier services to a lockbox bank, the contractor is to 
provide the lockbox bank with a disaster contingency plan. The plan 
must cover labor disputes, employee strikes, inclement weather, natural 
disasters, traffic accidents, and unforeseen events. Incomplete or 
inaccessible courier contingency plans increase the risk that courier 
service could be disrupted and that taxpayer receipts might not be 
timely deposited and taxpayer accounts might not be timely updated.

Recommendations:

We recommend that IRS:

* require that courier contracts call for couriers to submit 
contingency plans to lockbox banks,

* review lockbox bank courier contingency plans to help ensure that 
they incorporate all contingencies specified in the LPG,

* revise the LPG to specify that courier contingency plans be available 
at the lockbox banks, and:

* review lockbox bank courier and shredding contracts to ensure that 
they address all privacy-related criteria and include clear reference 
to privacy-related laws and regulations.

IRS Comments and Our Evaluation:

IRS agreed with our recommendations concerning lockbox bank courier 
contingency plans and adherence to requirements for inclusion of 
privacy-related requirements in lockbox bank courier and shredding 
contracts. To address these recommendations, IRS stated that (1) the 
LPG has been updated to require that courier services provide lockbox 
banks with a disaster contingency plan before their contract is 
implemented; (2) lockbox bank courier contingency plans have been 
reviewed by Lockbox Coordinators to ensure that the plans address all 
contingencies specified in the LPG; (3) the LPG would be updated by 
April 15, 2005, to require all lockbox banks to have the courier 
contingency plan available on site; and (4) the LPG had been updated on 
January 1, 2005, to specifically address privacy-related criteria, 
including references to pertinent sections of the Internal Revenue Code 
and the Privacy Act of 1974. We have verified the above-noted 
enhancements to the LPG during our ongoing fiscal year 2005 audit, and 
we will evaluate their effectiveness as we proceed with the audit. 
During the fiscal year 2005 financial audit, we will also evaluate the 
effectiveness of IRS's efforts with respect to reviewing lockbox bank 
courier contingency plans for completeness.

Verification of Lockbox Bank Deposits:

During our fiscal year 2004 audit, in reviewing deposit receipts--
receipts for deposits delivered by courier services to depositories--
maintained by courier services under contract to lockbox banks, we 
found that deposit receipts for three of the lockbox banks we visited 
did not always indicate the time and date deposits were received by 
depositories. In addition, we found that two of these lockbox banks did 
not obtain the deposit receipts from their courier services to verify 
that the depositories had in fact received the deposits in a timely 
manner.

GAO's Standards for Internal Control in the Federal Government requires 
that all transactions be clearly documented and that documentation be 
readily available for examination. Although the LPG requires that 
lockbox bank couriers, upon delivery of packages to designated sites, 
annotate time of delivery, it does not require that deposit receipts be 
time-and date-stamped or that they be returned to the lockbox bank. 
Unless receipts bear evidence of time and date of deposit and are 
promptly returned, lockbox banks cannot expeditiously verify timely 
deposit of receipts, thereby increasing the risk of theft or loss of 
taxpayer receipts and the risk that such theft or loss might not be 
promptly detected.

Recommendations:

We recommend that IRS:

* revise the LPG to require that (1) lockbox couriers promptly return 
deposit receipts to the lockbox banks following delivery of taxpayer 
remittances to depositories and (2) lockbox banks promptly review the 
returned deposit receipts;

* revise the LPG to require that deposit receipts for taxpayer 
remittances be time-and date-stamped; and:

* better enforce the LPG requirement that lockbox bank couriers 
annotate the time of delivery on receipts for deposits of taxpayer 
remittances.

IRS Comments and Our Evaluation:

IRS agreed with our recommendations concerning revisions to the LPG to 
require prompt return and review of deposit receipts and time-and date-
stamping of deposit receipts. IRS also agreed with our recommendation 
that it better enforce the LPG requirement that lockbox bank couriers 
annotate the time of delivery on receipts for deposits of taxpayer 
remittances. To address these recommendations, IRS stated that it had 
updated the LPG on January 1, 2005, to require that lockbox bank sites:

(1) receive back by the next business day the original completed 
Receipt for Transport of IRS Lockbox Bank Deposit form with the bank 
representative's name and signature, date, and time the deposit was 
received by the depository and (2) daily reconcile the Receipt for 
Transport of IRS Lockbox Bank Deposit form(s) to ensure receipt of 
dedicated service (i.e., that the time between the lockbox bank's 
release of the deposit to the courier and the courier's release of the 
deposit to the depository bank is not excessive). We have verified 
during our ongoing fiscal year 2005 financial audit that IRS updated 
the LPG, and we will evaluate the effectiveness of these enhancements 
as we proceed with the 2005 audit.

Procedures for Handling Taxpayer Receipts and Information by Couriers:

We have previously reported on various security weaknesses related to 
courier services at IRS service centers, field offices, and lockbox 
banks.[Footnote 10] IRS has made an effort to address such weaknesses 
by adopting more stringent security standards for the couriers who 
transport IRS's daily deposits to depository institutions. For example, 
IRS implemented a new lockbox courier policy requiring that more 
stringent background investigations of couriers be satisfactorily 
completed before granting them access to taxpayer receipts and 
information.

During our fiscal year 2004 audit, however, we found that IRS did not 
have controls in place to ensure that the courier requirements were 
effectively enforced. Specifically, we found the following:

* Couriers for two of the lockbox banks we visited did not always 
transport taxpayer receipts and information directly to their 
destination. In one case, we observed a courier vehicle make a pickup 
and then drive to and park at another location, where the vehicle and 
its contents remained for the rest of the day. In the other case, we 
observed a courier vehicle stop at an industrial park before proceeding 
to the depository institution.

* A courier van containing the morning pickup from one lockbox bank we 
visited was left unattended for approximately 30 minutes at the courier 
service office.

* Couriers for one lockbox bank made an unauthorized stop and 
transferred the contents of the courier vehicle to a pick-up truck.

* Solo couriers were permitted to transport taxpayer receipts and 
information for one service center and two lockbox banks we visited. At 
the service center, during our review of deposit receipts for the 2 
months prior to our visit, we found that in one instance the center's 
management permitted a solo courier to transport $47 million in 
receipts to the depository institution. Management informed us that it 
permitted this solo delivery because (1) the second courier was sick 
and the courier company was unable to provide another courier; (2) the 
deposit was large; and (3) it was a Friday, and delaying deposit until 
the following Monday would have resulted in loss of interest on the $47 
million over the weekend. With respect to the two lockbox banks, in one 
case we observed a courier vehicle depart the courier company with only 
one courier in the vehicle; in the other case, we observed a courier 
vehicle with two couriers make a pickup at the lockbox bank and then 
drop off one of the couriers before completing the delivery.

* Couriers were not wearing required uniforms at one service center and 
one lockbox bank we visited. At the service center, we observed that 
neither courier transporting deposits to the depository institution was 
wearing the required company logo shirt. In addition, one courier was 
not wearing an identification badge, which had instead been placed on 
the rearview mirror of the transport vehicle. Although lockbox banks 
have other ways to identify couriers, at the lockbox bank on two 
separate occasions, we observed couriers--two couriers in one case and 
one courier in the other case--who were not wearing company uniforms 
pick up taxpayer receipts and information.

Despite IRS's adoption of more stringent security standards for 
couriers who transport IRS's daily deposits to depository institutions, 
the findings above demonstrate that weaknesses continue to exist in 
IRS's enforcement of courier service procedures--specifically, those 
that require (1) courier service drivers to transport taxpayer receipts 
and information directly to their destination, with no stops in 
between; (2) vehicles to always be under the supervision of at least 
one courier and never left unattended; (3) courier service drivers to 
travel in pairs when transporting deposits; and (4) courier service 
drivers for lockbox banks to wear company uniforms. Nonadherence by 
couriers to IRS procedures increases the risk of loss, theft, or misuse 
of taxpayer receipts and information.

Recommendations:

We recommend that IRS:

* provide a written reminder to courier contractors of the need to 
adhere to all courier service procedures;

* periodically verify that contractors entrusted with taxpayer receipts 
and information offsite adhere to IRS procedures; and:

* develop alternative back-up plans that are consistent with IRS 
courier policies and procedures to address instances in which only one 
courier reports for transport of taxpayer receipts or information, such 
as requiring that a service center or lockbox bank employee accompany 
the courier to the depository.

IRS Comments and Our Evaluation:

IRS agreed with our recommendations that it provide a written reminder 
to courier contractors of the need to adhere to all courier service 
procedures, periodically verify that contractors entrusted with 
taxpayer receipts and information adhere to IRS procedures, and develop 
alternative back-up plans to address instances in which only one 
courier reports for transport of taxpayer receipts and information. IRS 
stated that it (1) intends to provide lockbox banks with a reminder to 
adhere to all courier service procedures, (2) has updated the LPG to 
provide that contractor adherence to IRS procedures will be monitored 
during periodic security reviews, and (3) intends to work with FMS to 
develop a plan by June 30, 2005, to address instances in which only one 
courier reports for transport of taxpayer receipts and information. We 
will evaluate the effectiveness of IRS's efforts during our fiscal year 
2005 financial audit.

Safeguarding Sensitive Systems and Equipment in Lockbox Banks:

At one of the lockbox banks we visited during our fiscal year 2004 
financial audit, we found that the electrical and water shutoff valves 
were in an area where janitors kept their supplies and which they 
accessed daily, and that the shutoff valves were not locked to prevent 
tampering. In addition, the security system control panel was located 
in the same area as the shutoff valves, and the keys to the security 
system control panel were left on top of the panel in this room. At the 
same lockbox bank, we also found that there were no surveillance 
cameras monitoring the security system controls and the water and 
electrical shutoff valves that were located in the janitors' supply 
room.

While the LPG does not address utility feeds located within the lockbox 
facility, it does require that utility feeds at the perimeter of 
lockbox banks be secured with locking devices and physically protected 
to prevent tampering or destruction. According to GAO's Standards for 
Internal Control in the Federal Government, agencies must establish 
physical control to secure and safeguard vulnerable assets, including 
providing security for, and limiting access to, equipment that might be 
vulnerable to unauthorized use. In addition, the LPG requires that 
items that need a higher level of security, including keys, be 
controlled and stored in containers to prevent theft and fraud. With 
respect to security closed-circuit television cameras, the LPG requires 
that they be deployed both generally and at critical locations 
throughout lockbox bank facilities to provide direct visual monitoring 
24 hours a day. Location of critical controls in frequently accessed 
areas and lack of effective monitoring of sensitive systems and 
equipment at lockbox banks increase the risk of unauthorized access, 
which in turn increases the risk of theft and misuse of taxpayer 
receipts and information.

Recommendations:

We recommend that IRS:

* formulate a policy to require that critical utility or security 
controls not be located in areas requiring frequent access,

* require lockbox bank management to position closed-circuit television 
cameras to enable monitoring of secured areas containing sensitive 
systems or controls, and:

* periodically monitor lockbox banks' adherence to the LPG requirement 
that keys be kept in secured containers within the secured perimeter.

IRS Comments and Our Evaluation:

IRS agreed with our recommendations concerning safeguarding of 
sensitive systems and equipment in lockbox banks. To require that 
critical utility or security controls not be located in areas requiring 
frequent access, IRS stated its intent to (1) ensure that policy 
guidelines address protection of critical or security controls and (2) 
work with the Business Operating Divisions and Procurement to 
incorporate any revised requirements into updated and future 
interagency agreements with FMS. With respect to requiring lockbox bank 
management to position closed-circuit television cameras to enable 
monitoring of secured areas containing sensitive equipment or controls, 
IRS indicated that as part of its Mission Assurance review process, it 
would review the use of closed-circuit television at the banks and, 
within local constraints, expand surveillance capabilities to include 
utility controls. With respect to periodically monitoring lockbox 
banks' adherence to the LPG requirement that keys be kept in secured 
containers within the secured perimeter, IRS stated that Mission 
Assurance will include controls over keys as part of any and all 
reviews. IRS also indicated that as part of the review process, it will 
work with the lockbox banks and lessors to improve security for keys 
and security panels, irrespective of ownership. We will evaluate the 
effectiveness of IRS's efforts during our fiscal year 2005 financial 
audit.

Candling Procedures:

IRS uses and requires lockbox banks to use a candling process to 
determine if any contents remain in open envelopes received from 
taxpayers before the envelopes are disposed of. Candling is often 
performed by passing the envelopes over a light source, although other 
methods mentioned in the 2004 LPG are also allowed, including opening 
an envelope on three sides and flattening it. The purpose of candling 
is to prevent the accidental destruction of taxpayer receipts and 
information.

As in previous years,[Footnote 11] we observed weaknesses in controls 
over candling of envelopes. The weaknesses we observed during our 
fiscal year 2004 audit are as follows:

At one of the lockbox banks we visited, the OPEX System 150, a high-
volume machine that extracts checks from envelopes by opening them on 
three sides, had been deemed by IRS to meet LPG candling requirements 
because the envelopes were flattened and traveled a distance of 3 
linear feet inside the machine before dropping into a bin. The OPEX 
System 150 entails no visual inspection of opened envelopes. Because 
envelopes opened by the OPEX System 150 are not visually inspected when 
they are laid flat, there is no assurance that all their contents have 
been properly removed. During our visit, we observed the envelopes 
falling into a bin, with no one watching them as they dropped. Once the 
bin was full, the envelopes were put into a garbage can to be shredded.

At one service center we visited, we observed light bulbs in candling 
tables in the final candling area that did not provide sufficient light 
for staff to see whether contents remained in opened envelopes.

The 2004 LPG candling requirement was unclear with respect to the 
number of candlings required for envelopes processed by OPEX equipment. 
Although the LPG stated that "envelopes must be candled twice before 
destruction" either through a light source or by splitting the 
envelopes on three sides and flattening them, the same section of the 
LPG also stated that splitting envelopes on three sides and flattening 
them "is sufficient to meet candling requirements without further light 
source viewing." IRS has no written guidelines for minimum wattage of 
bulbs in candling tables. Weaknesses in candling procedures increase 
the potential for inadvertent loss or destruction of taxpayer receipts.

Recommendations:

We recommend that IRS:

* assess technologies that may be exempt from the visual inspection 
requirement to determine whether they are acceptable methods of 
satisfying candling objectives and, if so, add such technologies to the 
LPG list of accepted candling methods;

* conduct an assessment of the costs and benefits of relying on only 
one candling when using certain automated equipment;

* clarify the LPG to eliminate confusion about the number of candlings 
required for different extraction methods; and:

* establish guidelines and a testing requirement to ensure satisfactory 
lighting conditions for effective candling.

IRS Comments and Our Evaluation:

IRS indicated that it has taken action to address issues that gave rise 
to our recommendations to (1) assess technologies that may be exempt 
from the visual inspection requirement to determine whether they are 
acceptable methods of satisfying candling objectives and, if they are, 
add them to the LPG list of accepted candling methods and (2) assess 
the costs and benefits of relying on only one candling when using 
certain automated equipment. IRS agreed with our recommendation to 
clarify the LPG to eliminate confusion about the number of candlings 
required for different extraction methods. IRS indicated that to 
address the issues raised by these recommendations, it added a 
provision to the 2005 LPG specifying that envelopes opened (either 
manually or by OPEX) on three or more sides must be candled once on the 
candling tables. During our ongoing fiscal year 2005 audit, we verified 
that IRS had made this change to the LPG, and we will evaluate the 
effectiveness of this enhancement as the audit progresses. IRS also 
agreed with our recommendation to establish guidelines and a testing 
requirement to ensure satisfactory lighting conditions for effective 
candling. IRS stated that additional work is needed to strengthen the 
current procedures in the Internal Revenue Manual (IRM) and that it is 
in the process of reviewing and strengthening these procedures. We will 
evaluate the effectiveness of IRS's efforts during our fiscal year 2005 
financial audit.

Monitoring and Verifying Recording and Transmittal of Taxpayer Receipts 
and Information:

When an IRS field office receives taxpayer receipts and returns, it is 
responsible for recording the information received and sending it to a 
service center for further processing with a transmittal form listing 
the documents included in the package. However, at the two IRS field 
offices we visited, we found multiple instances in which internal 
controls were not in place to ensure that recording and transmittal of 
taxpayer receipts and information were adequately monitored and 
verified:

At one field office, there was a lack of segregation of duties with 
respect to handling taxpayer receipts. We observed in seven Small 
Business/Self-Employed (SB/SE) units[Footnote 12] that the individuals 
responsible for preparing Payment Posting Vouchers were the same 
individuals who recorded the information from those vouchers on 
Document Transmittal forms, which list the contents of a package sent 
from one IRS location to another, and mailed those forms to the IRS 
service center. At the other field office, we observed that there was 
no independent review of documents or payments before they were mailed 
by their preparer to the service center for processing, nor was there 
any independent reconciliation of the information on the Document 
Transmittal forms to those documents or payments. In addition, at the 
same field office, there was no independent review or reconciliation of 
payments recorded on Daily Report of Collection Activity forms, which 
are used to list and transmit tax receipts and returns to service 
centers, to the actual payments that accompanied the forms before the 
payments were sent to the service center for processing.

One of the field offices sent Daily Report of Collection Activity forms 
to a service center without listing those forms on, and enclosing with 
them, a Document Transmittal form, as required by the IRM.[Footnote 13] 
Only packages containing a single Daily Report of Collection Activity 
form do not require an accompanying Document Transmittal form.

One of the field offices we visited did not use a logbook for filing 
Document Transmittal forms, and two units at the other field office had 
no system in place for maintaining and monitoring acknowledgments of 
Document Transmittal forms.

There was no evidence of management review of five units' Document 
Transmittal form logbooks at one of the field offices.

GAO's Standards for Internal Control in the Federal Government requires 
that key duties and responsibilities be segregated among different 
people to reduce the risk of error or fraud. In addition, according to 
the IRM, if a unit sends individually sealed envelopes in one package 
to the service center, the package must contain a Document Transmittal 
form listing the enclosed Daily Report of Collection Activity forms and 
the respective tracking information. The IRM also requires that senders 
establish a control to ensure delivery of tax receipts and information 
to IRS service centers and follow up within 10 work days on packages 
not acknowledged by the center. Not adequately accounting for taxpayer 
receipts because of insufficient review, reconciliation, monitoring, 
and segregation of duties increases the risk of error and fraud and, 
therefore, the potential for loss, theft, and misuse of taxpayer 
receipts.

Recommendations:

We recommend that IRS:

* establish policies and procedures to require appropriate segregation 
of duties in SB/SE units of field offices with respect to preparation 
of Payment Posting Vouchers, Document Transmittal forms, and 
transmittal packages;

* enforce the requirement that a Document Transmittal form listing the 
enclosed Daily Report of Collection Activity forms be included in 
transmittal packages, using such methods as more frequent inspections 
or increased reliance on error reports compiled by the service center 
teller units receiving the information;

* establish a procedure for SB/SE field office units to track Document 
Transmittal forms and acknowledgements of receipt of Document 
Transmittal forms; and:

* require evidence of managerial review of recording, transmittal, and 
receipt of acknowledgments of taxpayer receipts and information.

IRS Comments and Our Evaluation:

IRS agreed with our recommendations. To establish policies and 
procedures to require appropriate segregation of duties in SB/SE units 
of field offices with respect to preparation of Payment Posting 
Vouchers, Document Transmittal forms, and transmittal packages, IRS 
indicated that it will (1) establish procedure for SB/SE field office 
units to track Document Transmittal forms and acknowledgements of 
receipt of Document Transmittal forms and (2) strengthen its guidance 
to revenue officers and develop procedures specifically for field 
clerical staff. To enforce the requirement that a Document Transmittal 
form listing the enclosed Daily Report of Collection Activity forms be 
included in transmittal packages, IRS stated that its procedures will 
clarify that (1) the designated clerical contacts are responsible for 
bundling sealed envelopes into a single package for overnight mail to 
Submission Processing pursuant to the IRM and (2) the designated 
clerical contacts are to prepare a Document Transmittal form and send 
the prepared package to Submission Processing via overnight mail. IRS 
stated that these procedures will direct the designated clerical 
contact to retain a control copy of the Document Transmittal form and 
the overnight mail transmittal until the receipted copy of the Document 
Transmittal form is returned from Submission Processing. In addition, 
IRS said that it intends to require that the transmittal and the 
acknowledgement be reconciled monthly, with appropriate follow-up as 
required. IRS also stated its intent to issue a memorandum to all Field 
Assistance employees reminding them to adhere to these IRM requirements 
and to add this as a review item for operational reviews conducted by 
Field Assistance headquarters and area personnel. To establish a 
procedure for SB/SE field office units to track Document Transmittal 
forms and acknowledgements of receipt of Document Transmittal forms, 
IRS stated that it will clarify its procedures to require that managers 
ensure continuous coverage of the designated clerical contact duties so 
that absence due to illness or leave does not disrupt the processing of 
remittances. With respect to a requirement for evidence of managerial 
review of recording, transmittal, and receipt of acknowledgements of 
taxpayer receipts and information, IRS indicated that it will establish 
procedures to require documented evidence of such review, but noted 
that it will not implement any procedure that requires 100 percent 
managerial review. We will evaluate the effectiveness of IRS's efforts 
during our fiscal year 2005 financial audit.

Controls over the Generation of Automated Refunds in Automated 
Underreporter Program Cases:

Most refunds are generated automatically by IRS when taxpayers file tax 
returns reflecting a lower tax liability than the amount the taxpayer 
has paid. Upon receipt of a tax return, IRS records the tax liability 
for the appropriate tax period. If the taxpayer's payments and credits 
exceed the tax liability, an automated refund is generated.

In July of each year, after the peak tax filing period,[Footnote 14] 
IRS matches data submitted by taxpayers on their tax returns against 
data submitted to IRS by third parties to report earnings such as 
wages, interest, and dividends. This matching process is a key part of 
IRS's Automated Underreporter Program (AUR). IRS follows up on selected 
discrepancies identified as a result of the AUR to determine the reason 
for the discrepancy and attempt to collect any taxes due. If a 
discrepancy can be resolved by IRS based on review of available 
documentation, the case is closed. Otherwise, an underreporter notice, 
which informs the taxpayer of a proposed change to tax liability, is 
sent to the taxpayer. Because the taxpayer has not yet agreed to an 
additional tax assessment at this point, no tax liability is entered in 
the taxpayer's account. Instead, the underreporter notice includes a 
Consent of Assessment form which the taxpayer is asked to sign and 
return with his or her payment. When IRS receives this form with the 
payment, the form alerts employees to route the payment to the AUR 
unit, which is to record both the payment and the tax assessment in the 
taxpayer's account.

Taxpayers who receive an underreporter notice can choose to agree with 
the proposed additional assessment, disagree and provide reasons, or 
ask for an appeal. Once IRS sends an underreporter notice to a 
taxpayer, an AUR notice indicator is placed on the taxpayer's account 
within IRS's master files.[Footnote 15] IRS typically places a 
different type of indicator--known as a freeze code--on taxpayers' 
accounts that are undergoing examination or investigation. Freeze codes 
temporarily prevent the automated issuance of a refund until the issue 
is resolved and the freeze code is removed. An AUR notice indicator, 
however, does not on its own prevent issuance of an automated refund; 
rather, it serves as notice to other IRS units that AUR has control of 
the case and should be notified before any action is taken. 
Consequently, an automated refund may be improperly generated if a 
taxpayer submits a payment in response to an AUR notice but does not 
return a Consent of Assessment form with the payment.

At one of the two service centers we visited to review refund 
procedures during our fiscal year 2004 audit, we found two instances in 
which IRS generated refunds for taxpayers based on payments received in 
consideration of unpaid taxes identified by AUR. Both taxpayers 
received an AUR notice proposing a change in tax liability because of a 
discrepancy in their tax return, and both submitted a payment to IRS 
indicating agreement with IRS's finding. However, they did not enclose 
with their payment the form that accompanied the underreporter notice 
they received. As a result, IRS employees did not forward the payments 
to the AUR unit and instead recorded them on the taxpayers' accounts. 
Since no form had been received from these taxpayers and, consequently, 
the tax liabilities related to the payments had not been recorded in 
the taxpayers' accounts, the entire payment amounts were interpreted to 
be overpayments and refunds were disbursed. Weaknesses in IRS's 
controls over automated refund disbursements for accounts with AUR 
notice indicators unnecessarily expose the federal government to losses 
due to issuance of improper refunds.

Recommendation:

We recommend that IRS assess options to prevent the generation or 
disbursement of refunds associated with accounts with unresolved AUR 
discrepancies, including placement of a freeze or hold on all such 
accounts, until the AUR review has been completed.

IRS Comments and Our Evaluation:

IRS indicated that its existing procedures address the issue that gave 
rise to this recommendation. However, IRS stated that AUR will partner 
with Submissions Processing to ensure that employees receiving 
unidentified remittances are aware of the need to conduct IDRS research 
and how to properly post AUR remittances in these instances. We will 
evaluate the effectiveness of IRS's efforts during our fiscal year 2005 
financial audit.

Controls over Authorization of Manual Refunds:

During our fiscal year 2004 financial audit, we found weaknesses in 
IRS's controls over the authorization of manual refunds at both of the 
service centers we visited to review refund procedures during our 
fiscal year 2004 audit. These weaknesses resulted primarily from IRS 
employees not consistently adhering to policies and:

procedures intended to prevent disbursement of improper manual 
refunds.[Footnote 16] Specifically, IRS employees did not always (1) 
comply with IRS requirements when authorizing officials to approve 
manual refunds, (2) monitor or review the monitoring of accounts to 
prevent duplicate refunds or document that monitoring had been 
performed, or (3) review computer system command code profiles of 
approving employees and officials who certify that refund payments are 
proper to ensure that these officials did not have access to 
inappropriate command codes that would allow them to both process and 
approve or certify improper refunds.

Authorization to Approve Manual Refunds:

The IRM requires that all manual refunds be approved by officials who 
are designated by managers. To designate approving officials, managers 
are required to submit documents to the Manual Refund Unit that include 
the designated approving official's and manager's names and titles or 
positions, their telephone numbers, their IRS campus or field service 
organizations, their signatures, and a statement by the delegating 
manager certifying that sensitive command codes are not authorized for 
the approving official that would allow the official to both approve 
and process manual refunds.

At both service centers we visited to review refund procedures, 
however, we found that these controls were not always effective.

At one service center, we found documents authorizing approving 
officials that did not contain the delegating manager's signature and 
others that did not contain the authorized approving official's 
signature. We also found the name of an individual on the list of 
designated approving officials that had been on the list for about 9 
months even though the delegating manager had included a statement on 
the document requesting that the name remain on the list for only 90 
days.

At the other service center, we found documents that did not contain 
the name and title or position of the manager submitting the document.

Improper authorization of approving officials for manual refunds 
exposes the federal government to losses due to the increased risk of 
issuance of improper refunds.

Monitoring to Avoid Duplicate Refunds:

As we have previously reported,[Footnote 17] the risk of issuance of 
duplicate refunds is increased because (1) IRS's automated and manual 
refund systems are not adequately coordinated to prevent the issuance 
of a duplicate automated refund if a corresponding manual refund has 
already been generated and (2) manual refunds may not be posted to the 
taxpayer's account in the master file until up to 6 weeks after the 
refund has been issued to the taxpayer, potentially allowing a 
duplicate automated refund to be disbursed in the interim. To mitigate 
this risk, IRS has implemented various procedures, such as a 
requirement for employees who have initiated a manual refund to monitor 
the account to ensure that a duplicate automated refund does not post 
in the interim as a pending transaction. Supervisors are required to 
review the initiator's monitoring actions, and both the initiators and 
supervisors are required to document their monitoring or reviewing 
actions.

We have also previously reported that IRS employees did not always 
monitor accounts to prevent duplicate refunds and that they were not 
required to document their reviews. As a result of a previous 
recommendation we made, IRS revised its procedures to require 
documentation of monitoring actions and supervisory review of 
monitoring actions. However, at both service centers we visited, we 
found that this control was not always effective--IRS employees did not 
always monitor accounts to prevent duplicate refunds, and their 
supervisors did not always review monitoring actions to ensure that 
they were being properly conducted. We also found that IRS employees 
and supervisors did not always document their monitoring or reviewing 
actions. We interviewed nine manual refund initiators and their 
supervisors at the two service centers we visited to review refund 
procedures. During our review of documentation of their monitoring and 
reviewing procedures, we found the following:

Two initiators did not monitor the accounts to prevent duplicate 
refunds.

Of the seven initiators who did monitor the accounts, three did not 
sign and date their monitoring action.

Three initiators' supervisors did not review the monitoring actions.

Of the six supervisors who did review monitoring actions, only one 
documented, signed, and dated the review. Three of these supervisors 
documented but did not sign and date their review, and two did not 
document their review.

These weaknesses increase the risk that account monitoring and related 
reviews may not be conducted on a consistent and timely basis, 
rendering this control ineffective. As a result, IRS does not have 
adequate assurance that accounts are being appropriately monitored to 
prevent duplicate refunds from being paid.

Review and Approval of Command Code Profiles:

IRS uses IDRS, an online data retrieval and entry system, to process 
manual refunds. Employees' level of access to IDRS is determined by 
their specific role and responsibilities. Each employee who uses IDRS 
is assigned a command code profile that determines the type of 
transactions he or she can process. To ensure that approving officials 
do not have sensitive command codes that would allow them to process 
manual refunds in violation of segregation of duties requirements 
implemented to reduce the risk of error or fraud, IRS requires service 
centers to review command code profiles of approving officials. These 
individuals also review command code profiles of certifying officials, 
who are responsible for ensuring that refund payments are correct and 
proper.

At both service centers we visited to review refund procedures during 
our fiscal year 2004 financial audit, however, we found that command 
code profiles of approving and certifying officials were not always 
reviewed as required by the IRM.

At one service center, we found that the individual responsible for the 
review did not review the command code profiles for all authorized 
approving officials. Instead, only employees who had indicated or whose 
manager had indicated that they had been assigned command codes were 
selected for review. The reviewer did not verify that the employees who 
had indicated they did not have assigned command codes had not in fact 
been assigned command codes. In addition, no one at this service center 
reviewed the command code profiles of certifying officials.

At the other service center, we found that no review of command code 
profiles for approving officials had been conducted since July 2000, 
although the IRM requires that a review of the accounts and profiles of 
all users of IRS's network be conducted at least annually. For 
certifying officials at this service center, command code profiles had 
been reviewed monthly. However, since it was a certifying official who 
conducted the reviews, she also reviewed her own command code profile. 
The IRM does not specify who should conduct the reviews.

Because IRS employees did not always adhere to IRM requirements 
specifying control procedures over manual refunds and the IRM was not 
specific as to the timing and assignment of responsibility for 
reviewing command code profiles, the effectiveness of these controls 
was impaired. As a result, the risk is increased that IRS could 
disburse improper manual refunds.

Recommendations:

We recommend that IRS:

* enforce documentation requirements relating to authorizing officials 
charged with approving manual refunds,

* enforce requirements for monitoring accounts and reviewing monitoring 
of accounts,

* enforce requirements for documenting monitoring actions and 
supervisory review,

* enforce the requirement that command code profiles be reviewed at 
least once annually, and:

* specify in the IRM that staff members are not to review their own 
command code profiles.

IRS Comments and Our Evaluation:

IRS agreed with our recommendations concerning controls over 
authorization of manual refunds. With respect to the recommendations 
that call for enforcement of existing documentation, review, and 
monitoring requirements, IRS indicated its intent to remind management 
officials annually of these requirements via memorandum, notice, or 
Alert. IRS noted that as part of the reminder, checksheets will be 
included and a response will be required confirming that these actions 
have been taken. IRS also indicated that it will consider including 
these items in its Management Accountability Review Process. With 
respect to the recommendation that the IRM specify that staff members 
are not to review their own command code profiles, IRS stated that IRM 
wording would be updated and annual memorandums or notices would be 
sent to management officials reminding them that the approver's manager 
is responsible for ensuring that the approver's profiles have 
appropriate restrictions and have been reviewed. We will evaluate the 
effectiveness of IRS's efforts during our fiscal year 2005 financial 
audit.

Resolution of Liens with Manually Calculated Interest or Penalties:

During our fiscal year 2004 financial audit, we found that IRS did not 
properly verify interest or penalties on taxpayers' accounts with 
manually calculated interest or penalties to ensure that these 
taxpayers paid the full amount of taxes due before IRS released tax 
liens associated with their accounts. Specifically, none of the five 
lien units that we visited properly verified manual interest and 
penalties. Personnel at these lien units queried IDRS to see if it 
indicated that an account with a lien with manually calculated interest 
or penalties had been paid in full. If IDRS indicated that such an 
account had been paid in full, lien unit personnel incorrectly 
interpreted this to mean that there were no outstanding interest 
accruals or penalties and thus released the lien. However, IDRS does 
not make the manual interest and penalty calculations. Consequently, if 
IRS personnel do not verify that there are no unassessed interest or 
penalty amounts, they could close an account as having been fully paid 
when there are accumulated amounts of interest or penalties that are 
legally due to the government but that have not been assessed or paid.

Interest on most taxpayer accounts is calculated automatically by IDRS. 
However, IRS must manually calculate interest and penalties on some 
taxpayers' accounts because IDRS has not been programmed with the 
capability to calculate interest and penalties in accordance with 
certain legal requirements. IRS refers to such interest as "restricted 
interest" because IDRS is restricted from making the interest 
computations. For these cases, IRS officials must manually calculate 
the amount of interest or penalties due as of a point in time and 
manually enter the result into IDRS. However, these manually calculated 
interest or penalty amounts are not automatically updated with the 
passage of time to reflect new accruals of interest or penalties--
subsequent calculations of additional interest or penalties must also 
be done manually.

To help ensure that manually calculated interest and penalties are 
determined properly and that all accruals of interest and penalties are 
paid, IRS established a control to prevent the release of liens until 
the amounts of manually calculated interest and penalties are verified. 
Before releasing a lien, IRS automatically routes all accounts with 
manual calculations to the lien units. IRS guidance[Footnote 18] calls 
for lien unit personnel to verify the completeness of manual interest 
or penalty calculations before releasing the lien but does not show how 
this is to be done. Instead, it instructs lien unit personnel to 
"follow local procedures." However, none of the lien unit personnel we 
interviewed had local procedures for verifying the completeness of 
manual interest or penalty calculations. If lien units do not properly 
verify that there are no unassessed interest or penalty amounts for 
accounts with liens with manually calculated interest or penalties, 
there is a risk of loss of revenue to the federal government through 
the premature release of tax liens.

Recommendation:

We recommend that IRS specify in the IRM how to properly verify 
interest and penalties for accounts with liens with manually calculated 
interest or penalties.

IRS Comments and Our Evaluation:

IRS stated that it has taken actions to address the issue that gave 
rise to this recommendation. Specifically, IRS stated that it revised 
the IRM to instruct employees to check IDRS to determine if restricted 
interest or penalty is due. IRS noted that the IRM now clearly states 
that there are only two instances for which restricted interest and 
penalty should not be computed--offer-in-compromise and bankruptcy 
cases. In addition, IRS noted that tax examiners hired to staff the 
Centralized Case Processing Lien Processing Unit were provided hands-on 
training in the computation of restricted interest and penalty and that 
resolution of these cases moved to Centralized Case Processing 
effective February 2005. IRS also stated that the centralized site has 
created a special group of employees who were trained in the resolution 
of restricted interest and penalty cases and that new hires for this 
group:

will also receive this training. We will evaluate the effectiveness of 
IRS's efforts during our fiscal year 2005 financial audit.

Washington, D.C. 20548:

Dear Mr. Sebastian:

I am writing in response to your draft of the FY 2004 Management Report 
titled, Improvements Needed in the IRS' Internal Controls (GAO-05-
247R). I appreciate your continued assistance during our fiscal year 
financial statement audit. I believe the issues you presented in your 
report will help us to take the necessary steps to strengthen our 
controls over safeguarding tax receipts, and to improve financial 
management.

Over the last several years we have made significant progress in 
addressing our financial management challenges, and we have resolved or 
substantially mitigated several material weaknesses in our internal 
controls, including those affecting Treasury Fund balance, budgetary 
activities, and property and equipment. We are pleased, for the first 
time, that your yearly audit report contains no recommendations related 
to operational deficiencies in the Service's administrative accounting 
procedures. Because of the number of open recommendations related to 
lockbox issues, the IRS responsibly designated these issues as a 
reportable condition. We have also developed a comprehensive action 
plan to address the lockbox weaknesses identified in your report and 
will monitor the plan through its implementation. I have enclosed a 
response which addresses each of your 30 recommendations.

In closing, we are committed to improving our internal controls and 
have identified actions to improve the areas identified in your report. 
We look forward to continuing to work with the GAO to overcome the 
weaknesses cited in your report. If you have any questions, please 
contact Janice Lambert, Chief Financial Officer, at (202) 622-6400.

Sincerely,

GAO Recommendations and IRS Responses to GAO FY 2004 Management Report 
Improvements Needed in the IRS' Internal Controls GAO-05-247R:

Recommendation: Enforce IRS' existing requirement that appropriate 
background investigations be completed for contractors before they are 
granted staff-like access to service centers.

Comments: We believe we have addressed this recommendation. We have 
implemented steps to monitor and enforce the requirements we issued on 
September 29, 2003, on the issuance of ID cards to contractors. Our 
guidance requires that a letter from the National Background 
Investigation Center (NBIC) indicating successful completion of at 
least an interim background investigation be received by the issuing 
office before a contractor can be approved for staff-like access to 
IRS. The guidance further stipulates that Physical Security staff 
would, on at least a 6-month basis, make sure that a re-certification 
is received from the Contracting Officers Technical Representatives 
(COTR) and confirms the contractors' need for continued staff-like 
access to the IRS facility. Additionally, as part of the required 
records and accountability process, non-Federal photo ID cards are 
audited annually by the issuing office to reconcile numerical and 
alphabetical files and to assure that ID cards have been recovered upon 
separation or termination of the contract.

Recommendation: Require that background investigation results for 
contractors (or evidence thereof) be on file where necessary, including 
at contractor worksites and security offices responsible for 
controlling access to sites containing taxpayer receipts and 
information.

Comments: We agree with this recommendation. In the guidance memorandum 
we issued on September 29, 2003, the Physical Security Program Office 
requires COTRs to complete and submit a request form for every contract 
employee. Implementation of the standardized form assures that all 
required information is provided in order for the contractor to receive 
its IRS photo ID card. This guidance also requires that a copy of the 
letter from NBIC indicating successful completion of at least an 
interim background investigation be attached to the request form or no 
ID card will be issued. Both documents are maintained by the issuing 
office. The IRS COTR for the lockbox banks verified that all six banks 
currently maintain background investigation records, including copies 
of documents submitted to NBIC and lists of cleared personnel. The 
Physical Security Program Office will work with the Business Operating 
Divisions (BOD) and Procurement to determine if the interagency 
agreement with Financial Management Services (FMS) should be modified 
to include a requirement for lockbox banks to maintain background 
investigation files. The estimated completion date for the review of 
the interagency agreement is November 2005.

Recommendation: Require that courier contracts call for couriers to 
submit contingency plans to lockbox banks.

Comments: We agree with this recommendation. The Lockbox Processing 
Guidelines (LPG) was updated on January 1, 2005--LPG 4.2.3.1 (01-01-
2005) Courier Contingency Plan--to require that prior to implementation 
of the contract, the courier service must provide the lockbox with a 
disaster contingency plan. The contingency plan must cover labor 
disputes, employee strikes, inclement weather, natural disasters, 
traffic accidents, and unforeseen events.

Recommendation: Review lockbox bank courier contingency plans to help 
ensure that they incorporate all contingencies specified in the LPG.

Comments: We agree with this recommendation. Contingency plans were 
provided by all lockbox sites and are part of the Filing Season 
Readiness (FSR) Plan. LPG 4.2.3.1 states "the contingency plan must 
cover labor disputes, employee strikes, inclement weather, natural 
disasters, traffic accidents, and unforeseen events." The Lockbox 
Coordinators reviewed the contingency plans to ensure that these issues 
were addressed.

Recommendation: Revise the LPG to specify that courier contingency 
plans be available at the lockbox banks.

Comments: We agree with this recommendation. LPG 2.1.7 requires each 
lockbox bank to submit an annual FSR Plan. The plan must be submitted 
to the Lockbox Field Coordinators for review to ensure each site is 
prepared for the filing season. Lockbox Field Coordinators will ensure 
all contingencies specified in the LPG are incorporated in the 
contract. Additionally, the LPG will be updated by April 15, 2005, to 
require all lockbox banks to have the courier contingency plan 
available on site.

Recommendation: Review lockbox bank courier and shredding contracts to 
ensure that they address all privacy-related criteria and include clear 
reference to privacy-related laws and regulations.

Comments: We agree with this recommendation. The LPG was updated on 
January 1, 2005--LPG 4.2.3(2), Courier Services--which requires lockbox 
banks to ensure all bonded courier/armored car agreements contain the 
following language: "As an independent contractor, courier/armored car 
company under contract with the Financial Institution (FI), I fully 
understand that much of the information provided to (name of the 
courier/armored car company) and its employees is privileged, legally 
and administratively restricted and falls under the provisions of the 
Privacy Act of 1974 and the Internal Revenue Code (IRC) Sections 6103, 
7213, and 7131. The Privacy Act, the safeguards, and the criminal/civil 
sanctions paragraphs specify (name of the courier/armored car 
company's) responsibility and liability regarding disclosure of this 
information. At the expiration of (name of the courier/armored car 
company's) contract with the Fl, (name of the courier/armored car 
company) is required to return all documents in its possession to the 
Internal Revenue Service." We will monitor this action during on-site 
reviews.

Recommendation: Revise the LPG to require that (1) lockbox couriers 
promptly return deposit receipts to the lockbox banks, following 
delivery of taxpayer remittances to depositories and (2) lockbox banks 
promptly review the returned deposit receipts.

Comments: We agree with this recommendation. The LPG was updated on 
January 1, 2005--LPG 4.2.3.1.8, Receipt for Transport of IRS Lockbox 
Bank Deposit Form--which requires the lockbox site to receive back by 
the next business day the original completed Receipt for Transport of 
IRS Lockbox Bank Deposit Form with the bank representative's name and 
signature, date and time the deposit was received by the depository. 
The guidance also requires the lockbox site to reconcile daily the 
Receipt for Transport of IRS Lockbox Bank Deposit Form(s) to ensure 
receipt of dedicated service (e.g., the time between your release to 
the courier and the release to the bank is not in excess). If 
discrepancies are found, the Lockbox Field Coordinator should be 
notified immediately.

Recommendation: Revise the LPG to require that deposit receipts for 
taxpayer remittances be time and date-stamped.

Comments: We agree with this recommendation. The LPG was updated on 
January 1, 2005--LPG 4.2.3.1.8, Receipt for Transport of IRS Lockbox 
Bank Deposit Form-to require the courier service employee to return 
the form to the lockbox site on the next business day, ensuring the 
following information is completed on the form: the depository bank 
employee's name and signature, the date the deposit was received by the 
depository, and the time the deposit was received by the depository.

Recommendation: Better enforce the LPG requirement that lockbox bank 
couriers annotate the time of delivery on receipts for deposits of 
taxpayer remittances.

Comments: We agree with this recommendation. The LPG was updated on 
January 1, 2005--LPG 4.2.3.1.8, Receipt for Transport of IRS Lockbox 
Bank Deposit Form-to require lockbox bank couriers to annotate the 
time of delivery of receipts for deposits of taxpayer remittances.

Recommendation: Provide a written reminder to courier contractors of 
the need to adhere to all courier service procedures.

Comments: We agree with this recommendation. We will develop an annual 
memorandum by January 1, 2006, to require banks to remind courier 
contractors to adhere to all courier service procedures in the LPG. We 
will monitor adherence during site reviews.

Recommendation: Periodically verify that contractors entrusted with 
taxpayer receipts and information offsite adhere to IRS procedures.

Comments: We agree with this recommendation. The 2005 LPG 4.2.3.1.8(1) 
has been updated, and the procedures will be monitored during the 
periodic Security Reviews.

Recommendation: Develop alternative, back-up plans that are consistent 
with IRS courier policies and procedures to address instances in which 
only one courier reports for transport of taxpayer receipts or 
information, such as requiring that a service center or lockbox bank 
employee accompany the courier to the depository.

Comments: We agree with this recommendation. We will work with FMS to 
develop an alternative back-up plan by June 30, 2005.

Recommendation: Formulate a policy to require that critical utility or 
security controls not be located in areas requiring frequent access.

Comments: We agree with this recommendation. We will ensure policy 
guidelines address protection of critical or security controls. We will 
work with the BODs and Procurement to incorporate any revised 
requirements into updated and future interagency agreements with FMS.

Recommendation: Require lockbox bank management to position closed-
circuit television cameras to enable monitoring of secured areas 
containing sensitive systems or controls.

Comments: We agree with this recommendation. The IRS, through 
Procurement, enters into an interagency agreement with FMS for lockbox 
services, which in turn makes arrangements with banks. These 
arrangements are non-procurement contracts that require adherence to 
the IRS LPG. Internal Revenue Manual (IRM) 3.0.230.5 (dated 1-20-05) 
indicates the Revenue and Deposit Branch, Lockbox Policy and 
Procedures: "coordinates with FMS any new or updated processing 
changes, obtains data for the re-bidding of contract(s) and finalizes 
the Lockbox Processing Guidelines (LPG)." Since lockbox banks are 
already required to comply with the IRS LPG, there is no need for the 
COTR to do anything else. The LPG does require and the lockbox banks 
have installed cameras to monitor critical areas and assets in those 
parts of a facility controlled by the banks. As part of the Mission 
Assurance review process, we will review the use of closed-circuit 
television at the banks and, within local constraints, expand 
surveillance capabilities to include utility controls.

Recommendation: Periodically monitor lockbox banks' adherence to the 
LPG requirement that keys be kept in secured containers within the 
secured perimeter.

Comments: We agree with this recommendation. The LPG guidelines require 
that keys and panels controlled by the banks should be properly stored 
and secured and Mission Assurance will include key control as part of 
any and all reviews. As part of the review process, we will work with 
the banks and lessors to improve security for keys and security panels, 
irrespective of ownership.

Recommendation: Assess technologies that may be exempt from the visual 
inspection requirement to determine whether they are acceptable methods 
of satisfying candling objectives and, if so, add such technologies to 
the LPG list of accepted candling methods.

Comments: We feel we have addressed this recommendation in the 2005 
LPG, and have shared this information with GAO. We determined current 
technologies are not exempt from the candling requirement and added to 
the 2005 LPG 3.2.8 (1) envelopes opened (either manually or by OPEX) on 
three or more sides must be candled once on the candling tables. All 
other envelopes must be candled twice on the candling tables.

Recommendation: Conduct an assessment of the costs and benefits of 
relying on only one candling when using certain automated equipment.

Comments: We feel we have addressed this recommendation in the 2005 LPG 
and have shared this information with GAO. We assessed the candling 
functions on automated equipment and included in the 2005 LPG under 
3.2.8 section (1) a requirement that envelopes opened (either manually 
or by OPEX equipment) on three or more sides must be candled once on 
the candling tables. We will monitor adherence during site reviews.

Recommendation: Clarify the LPG to eliminate confusion about the number 
of candlings required for different extraction methods.

Comments: We agree with this recommendation. We have updated the 2005 
LPG under 3.2.8, "Candling" to require envelopes opened (either 
manually or by OPEX) on three or more sides must be candled once on the 
candling tables. All other envelopes must be candled twice on the 
candling tables.

Recommendation: Establish guidelines and a testing requirement to 
ensure satisfactory lighting conditions for effective candling.

Comments: We agree with this recommendation. The IRS agrees that 
additional work is needed to strengthen the current procedures 
contained in IRM 3.10.72, Batching, Sorting and Numbering. Currently, 
our Campus management tests 10 envelopes at the start of each shift to 
ensure that maximum envelope recognition is met and that all contents 
left in envelopes can be easily detected. The IRS is in the process of 
reviewing and strengthening these procedures.

Recommendation: Establish policies and procedures to require 
appropriate segregation of duties in SB/SE units of field offices with 
respect to preparation of Payment Posting Vouchers, Document 
Transmittal forms, and transmittal packages.

Comments: We agree with this recommendation. We will establish a 
procedure(s) for SB/SE field office units to track Document Transmittal 
forms and acknowledgements of receipt of Document Transmittal forms.

We currently have numerous procedures in place which provide guidance 
to revenue officers regarding the processing of returns and payments. 
However, we do not currently have procedures specifically for our field 
clerical staff. We will strengthen our guidance to revenue officers and 
will develop procedures specifically for our field clerical staff.

Our procedures will clarify that revenue officers are responsible for 
submitting an appropriately labeled sealed envelope containing the 
Daily Report of Collection Activity form to a designated clerical 
contact in the Post of Duty (POD). This guidance will apply unless the 
revenue officers are working away from the POD on extended field calls 
or Flexiplace, or are working in a single revenue officer POD. Those 
revenue officers will send the envelope directly to Submission 
Processing.

Recommendation: Enforce the requirement that a Document Transmittal 
form listing the enclosed Daily Report of Collection Activity forms be 
included in transmittal packages, using such methods as more frequent 
inspections or increased reliance on error reports compiled by the 
service center teller units receiving the information.

Comments: We agree with this recommendation. Our procedures will 
clarify that the designated clerical contacts are responsible for 
bundling the sealed envelopes into a single package for overnight mail 
to Submission Processing pursuant to the IRM. The procedures will also 
clarify that the designated clerical contacts will prepare a Document 
Transmittal form and send the prepared package to Submission Processing 
via overnight mail. The procedures will direct the designated clerical 
contact to retain a control copy of the Document Transmittal form and 
the overnight mail transmittal until the receipted copy of the Document 
Transmittal form is returned from Submission Processing. We will also 
require that the transmittal and the acknowledgement be reconciled on a 
monthly basis, with appropriate follow-up as required.

The Taxpayer Assistance Center, GAO visited, was instructed to ensure 
that a Document Transmittal form be prepared and enclosed in the 
package when multiple Daily Reports of Collection Activity are sent to 
the service center. We will issue a memorandum to all Field Assistance 
employees reminding them to adhere to these IRM requirements. We will 
also add this as a review item for operational reviews conducted by 
Field Assistance headquarters and area personnel.

Recommendation: Establish a procedure for SB/SE field office units to 
track Document Transmittal forms and acknowledgements of receipt of 
Document Transmittal forms.

Comments: We agree with this recommendation. Our procedures will 
clarify that the managers should ensure continuous coverage of the 
designated clerical contact duties so that absence due to illness or 
leave does not disrupt the processing of remittances.

Recommendation: Require evidence of managerial review of recording, 
transmittal, and receipt of acknowledgments of taxpayer receipts and 
information.

Comments: We agree with this recommendation. We will establish a 
procedure(s) to require evidence of managerial review of recording, 
transmittal, and receipt of acknowledgements of taxpayer receipts and 
information. However, we will not implement any procedure requiring 100 
percent managerial review.

The new procedure(s) will call for random managerial spot-checking of 
packages prepared for submission to Submission Processing by revenue 
officers working in PODS or by the designated clerical contacts in the 
PODS. The new procedure(s) will not call for any random managerial 
spot-checking of packages prepared by revenue officers working away 
from the POD on extended field calls or Flexiplace. Instead, on those 
packages, we will continue to rely on the remittance reviews conducted 
by remittance processing personnel in Submission Processing. These 
reviews will be documented by the revenue officer group manager and be 
retained for the appropriate period required under record management 
guidelines.

Recommendation: Assess options to prevent the generation or 
disbursement of refunds associated with accounts with unresolved 
Automated Underreporter Program (AUR) discrepancies, including 
placement of a freeze or hold on all such accounts, until the AUR 
review has been completed.

Comments: We feel the procedures that we have in place adequately 
address preventing the generation or disbursement of refunds associated 
with AUR accounts if followed. Submissions Processing's IRM 3.8.45 
requires employees receiving an unidentified remittance to conduct 
Individual Data Retrieval System (IDRS) research to determine if there 
is an open account that allows for posting of the remittance. AUR cases 
are identified in IDRS by transaction code (TC) 922.

Once the TC 922 is found through research, the remittance should be 
posted as a TC 640 which is an "Advanced Payment of Determined 
deficiency or Underreporter Proposal." In the cases identified by GAO 
it is apparent that appropriate IDRS research was not conducted or 
remittances were posted erroneously as a TC 610 which will refund out 
if the taxpayer's tax return does not indicate a balance due. AUR will 
partner with Submissions Processing to ensure that employees receiving 
unidentified remittances are aware of the need to conduct IDRS 
research, and how to properly post AUR remittances in these instances.

Recommendation: Enforce documentation requirements relating to 
authorizing officials charged with approving manual refunds.

Comments: We agree with this recommendation. We will enforce 
requirements to document monitoring by reminding management officials 
annually via a memorandum, notice or an Alert. As part of the reminder, 
the IRM check sheets will be included and a response will be required 
confirming these actions have been taken. In addition, we will consider 
including this item in the Management Accountability Review Process.

Recommendation: Enforce requirements for monitoring accounts and 
reviewing monitoring of accounts.

Comments: We agree with this recommendation. We will enforce monitoring 
requirements by reminding management officials annually via a 
memorandum, notice or an Alert. As part of the reminder, the IRM check 
sheets will be included and a response will be required confirming 
these actions have been taken. In addition, we will consider including 
this item in the Management Accountability Review Process.

Recommendation: Enforce requirements for documenting monitoring 
actions and supervisory review.

Comments: We agree with this recommendation. We will enforce 
requirements to document monitoring by reminding management officials 
annually via a memorandum, notice or an Alert. As part of the reminder, 
the IRM check sheets will be included and a response will be required 
confirming these actions have been taken. In addition, we will consider 
including this item in the Management Accountability Review Process.

Recommendation: Enforce the requirement that command code profiles be 
reviewed at least once annually.

Comments: We agree with this recommendation. We will enforce annual 
review of command code profiles by reminding management officials 
annually via a memorandum or notice. As part of the reminder, the IRM 
check sheets will be included and a response will be required 
confirming these actions have been taken. In addition, we will consider 
including this in the Management Accountability Review Process.

Recommendation: Specify in the IRM that staff members are not to review 
their own command code profiles.

Comments: We agree with this recommendation. IRM wording will be 
updated and recommendations will be included in annual reminders 
(memos/notices, etc,) to management officials that the approver's 
manager is responsible for ensuring that approver's profiles have 
appropriate restrictions and have been reviewed.

Recommendation: Specify in the IRM how to properly verify interest and 
penalties for accounts with liens with manually calculated interest or 
penalties.

Comments: We have taken actions to implement this recommendation. 
During the Fiscal Year 2004 financial audit, GAO determined that IRS 
did not properly verify restricted interest and penalty computations 
before releasing the federal tax lien in some instances. GAO recommends 
that restricted interest and penalty methodology be included in the 
Federal Tax Lien, Internal Revenue Manual. We agree that an account 
with a zero balance "assessed" status does not mean that additional 
accruals are not due. We also agree that additional guidance was needed 
in this area. The newly revised IRM instructs employees to check IDRS 
to determine if restricted interest or penalty is due. The IRM now 
clearly states that there are only two instances where restricted 
interest and penalty should not be computed, offer-in-compromise and 
bankruptcy cases.

Also, instructions for computing restricted interest and penalty are 
found in the Automated Lien System (ALS) User Guide as well as in 
training material and desk guides. In addition, tax examiners hired to 
staff the Centralized Case Processing (CCP), Lien Processing Unit were 
provided hands on training in the computation of restricted interest 
and penalty. Resolution of these cases moved to CCP effective February 
2005. The centralized site has created a special group of employees who 
were trained in the resolution of restricted interest and penalty 
cases. New hires for this group will also receive this training. 

Details on Audit Methodology:

To fulfill our responsibilities as the auditor of the Internal Revenue 
Service's (IRS) financial statements, we did the following:

Examined, on a test basis, evidence supporting the amounts and 
disclosures in the financial statements. This included testing selected 
statistical samples of unpaid assessment, revenue, refund, accrued 
expenses, payroll, nonpayroll, property and equipment, and undelivered 
order transactions. These statistical samples were selected primarily 
to substantiate balances and activities reported in IRS's financial 
statements. Consequently, dollar errors or amounts can and have been 
statistically projected to the population of transactions from which 
they were selected. In testing these samples, certain attributes were 
identified that indicated either significant deficiencies in the design 
or operation of internal control or compliance with provisions of laws 
and regulations. These attributes, where applicable, can be and have 
been statistically projected to the appropriate populations.

Assessed the accounting principles used and significant estimates made 
by management.

Evaluated the overall presentation of the financial statements.

Obtained an understanding of internal controls related to financial 
reporting (including safeguarding assets), compliance with laws and 
regulations (including the execution of transactions in accordance with 
budget authority), and performance measures reported in the Management 
Discussion and Analysis.

Tested relevant internal controls over financial reporting (including 
safeguarding assets) and compliance, and evaluated the design and 
operating effectiveness of internal controls.

Considered the process for evaluating and reporting on internal 
controls and financial management systems under 31 U.S.C. § 3512 (c), 
(d), commonly referred to as the Federal Managers' Financial Integrity 
Act of 1982.

Tested compliance with selected provisions of the following laws and 
regulations: Anti-Deficiency Act, as amended (31 U.S.C. § 1341(a)(1) 
and 31 U.S.C. § 1517(a)); Agreements for payment of tax liability in 
installments (26 U.S.C. § 6159); Purpose Statute (31 U.S.C. § 1301); 
Release of lien or discharge of property (26 U.S.C. § 6325); Interest 
on underpayment, nonpayment, or extensions of time for payment of tax 
(26 U.S.C. § 6601); Interest on overpayments (26 U.S.C. § 6611); 
Determination of rate of interest (26 U.S.C. § 6621); Failure to file 
tax return or to pay tax (26 U.S.C. § 6651); Failure by individual to 
pay estimated income tax (26 U.S.C. § 6654); Failure by corporation to 
pay estimated income tax (26 U.S.C. § 6655); Prompt Payment Act (31 
U.S.C. § 3902(a), (b), and (f) and 31 U.S.C. § 3904); Fair Labor 
Standards Act of 1938, as amended (29 U.S.C. § 206); Civil Service 
Retirement Act of 1930, as amended (5 U.S.C. §§ 5332, 5343); Federal 
Employees' Retirement System Act of 1986, as amended (5 U.S.C. §§ 8422, 
8423, and 8432); Social Security Act, as amended (26 U.S.C. §§ 3101 and 
3121 and 42 U.S.C. § 430); Federal Employees Health Benefits Act of 
1959, as amended (5 U.S.C. §§ 8905, 8906, and 8909); and Consolidated 
Appropriations Act, 2004, Pub. L. No. 108-199, 118 Stat. 3 (Jan. 23, 
2004).

Tested whether IRS's financial management systems substantially comply 
with the three requirements of the Federal Financial Management 
Improvement Act of 1996 (Pub. L. No. 104-208, div. A, § 101(f), title 
VIII, 110 Stat. 3009, 3009-389 (Sept. 30, 1996) (codified at 31 U.S.C. 
§ 3512 note).

Statements, GAO-05-103 (Washington, D.C.: Nov. 10, 2004).

[2] Lockbox banks are financial institutions designated as depositories 
and financial agents of the U.S. government to perform certain 
financial services, including processing tax documents, depositing the 
receipts, and then forwarding the documents and data to IRS's service 
center campuses, which update taxpayers' accounts.

[3] Staff-like access consists of unescorted access to IRS-owned or 
controlled facilities, information systems, security items and 
products, or sensitive but unclassified information.

[4] Internal Revenue Service, "2004 Lockbox Processing Guidelines" 
(Washington, D.C: January 2004), and subsequent 2004 updates. The 2004 
LPG provides guidelines for processing work at lockbox banks serving 
IRS for the 2004 tax processing year.

[5] Candling is a process used by IRS to determine if any contents 
remain in open envelopes, which is often achieved by passing the 
envelopes over a light source.

[6] Lien units are separate offices established by IRS to handle lien 
processing, including release of tax liens. As of June 1, 2004, IRS had 
33 lien units located throughout the United States. IRS is currently 
reorganizing the physical structure and management of its lien units 
and by mid-2005 plans to have consolidated them into one physical 
location, called the Central Lien Processing Unit, at its Cincinnati 
campus.

self-employed individuals, individual filers with certain types of 
nonsalary income, and small businesses.

[13] The IRM outlines business rules and administrative procedures and 
guidelines IRS uses to conduct business and contains policy, direction, 
and delegations of authority necessary to carry out IRS 
responsibilities to administer tax law and other legal provisions.

[14] IRS's master files contain detailed records of taxpayer accounts.

[15] Most refunds are generated automatically; under certain 
circumstances, however, IRS processes refunds manually to expedite 
payment. Such refunds include those over $10 million, those requested 
by taxpayers for immediate payment due to hardship or emergency, those 
to beneficiaries of deceased taxpayers, and those that need to be 
expedited because IRS is in jeopardy of paying interest for exceeding 
the 45-day limit for processing a return.
