MEMORANDUM FOR DAVID A. GRANT
DIRECTOR OF PROCUREMENT
INTERNAL
REVENUE SERVICE
FROM: Daniel R. Devlin /s/ Daniel R. Devlin
Assistant Inspector General for Audit (Headquarters Operations
and Exempt Organizations Programs)
SUBJECT: Report on Audit of Billing System Internal Controls (Audit # 20051C0234)
The
Defense Contract Audit Agency (DCAA) examined the contractor’s billing system as
of September 21, 2004, to assure that the contractor’s billing system and
related internal controls comply with applicable laws and regulations, are effective
over compliance, and are adequate and operating effectively. Test procedures were applied from May through
September 2004.
According
to the DCAA, the contractor’s overall billing system and related internal
control policies and procedures are adequate. However, during the course of the examination,
the DCAA noted matters involving the billing system and related internal
controls that, although not considered significant deficiencies at this time,
the DCAA believes should be communicated to the contractor’s management. These matters are detailed in the “Suggestion
to Improve the System.” The DCAA
examined only the overall billing system.
Accordingly, the DCAA expresses no opinion on the contractor’s system of
internal controls taken as a whole.
The DCAA
audit report was dated September 2004; however, we did not receive a copy of
the report until August 2005. Neither
the Internal Revenue Service nor the Treasury Inspector General for Tax
Administration is shown on the DCAA report distribution list. We are transmitting the report to you to
assist in the management of the contract and to enable the Internal Revenue Service
to track any financial accomplishments derived from negotiations with the contractor
based on results from the DCAA report.
The
information in this report
should not be used for purposes other than those intended without prior
consultation with the Treasury Inspector General for Tax Administration
regarding their applicability.
If you have any questions, please contact me at (202) 622-8500 or
John R. Wright, Director, at (202) 927-7077.
