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 #200310002.022)
The Defense
Contract Audit Agency (DCAA) examined the Civil Group’s billing system as of
June 19, 2002. The purpose of this
examination was to assure that the Civil Group’s system of billing controls is
adequate to provide billed costs that are reasonable, compliant with applicable
laws and regulations, and subject to applicable financial control systems. The DCAA also evaluated the Civil Group’s
compliance with the billing system’s internal control requirements.
The DCAA
opined that the billing system and related internal control policies and
procedures of the Civil Group are inadequate.
The examination disclosed significant internal control deficiencies in
the Civil Group’s billing system that could result in an overpayment on United
States Government contracts. The DCAA
noted that these deficiencies could adversely affect the organization’s ability
to prepare billings in accordance with applicable laws, regulations, and
contract terms. In addition, the DCAA
also indicated that these deficiencies could adversely affect the
organization’s ability to prevent or detect material misstatements and correct
them in a timely manner.
Specifically,
the DCAA listed nine significant issues that formed the basis of its opinion,
including: lack of consistent “formal”
policies and procedures; provisional billing rates not properly adjusted; lack
of written policies and procedures for preparing manual bills; lack of separate
written policies for Internal Revenue Service billing procedures; lack of
written policy for reviewing the adequacy of subcontractors’ systems;
inadequate written policies for processing contract overpayments, refunds, and
offsets; and, no management reviews or internal audits of the billing system.
The DCAA was
unable to determine the precise cost impact of these deficiencies. However, during Fiscal Year 2001, the Civil
Group’s billing system processed over $990 million of invoices to the
government. The
DCAA made numerous recommendations to resolve the deficiencies.
The
information in this report should not be used for purposes other than that
intended without prior consultation with the Treasury Inspector General for Tax
Administration regarding its applicability.
If you have any questions, please
contact me at (202) 622-8500 or John R. Wright, Director at (202) 927-7077.
