IMPACT ON TAXPAYERS
Most Internal
Revenue Service (IRS) mission critical programs rely on contract support. Because contract expenditures represent a
significant outlay of IRS funds, TIGTA performed 16 audits of these
expenditures and determined that the internal controls and practices the IRS
had in place to verify contract charges were not effective. Without effective practices and internal
controls to verify contract charges, the IRS is at risk of making improper
payments and misusing taxpayer funds.
WHY TIGTA DID THE AUDIT
This
audit was conducted to perform a trend analysis of common issues and findings
identified in previously issued invoice and voucher audits. The purpose of our
audit was to answer the following questions:
1. What
are the common issues and findings from TIGTA audit reports and the Defense
Contract Audit Agency audit reports related to invoice/voucher processing?
2. Were the planned corrective actions taken to
resolve the individual conditions identified in TIGTA audit reports?
3. Are there any systemic control or process
weaknesses that warrant improvement to the IRS’ procurement activities?
WHAT
TIGTA FOUND
TIGTA identified
weaknesses in the control environment regarding the voucher/invoice
verification process in 15 of the 16 audit reports issued from September 2003
through April 2007. The IRS did not
perform comprehensive verifications of actual hours worked or a detailed review
of travel expenses but simply accepted the contractors’ certifications. In 2 of the 16 reports, the IRS was not
verifying the skills/qualifications of the contractor employees and, therefore,
overpaid contractors for employees not qualified for the charged
positions. Another result of ineffective
controls is the potential for nonidentification of illegal acts. TIGTA identified two instances of contractors
submitting false claims for reimbursement.
This overall weak control environment puts the IRS at risk for making
improper payments. In response to our
audits, Procurement developed a Guidebook for Acquisition Practices (Guidebook)
that provides a detailed process for reviewing vouchers/invoices. Unless adequate supporting documentation for
charges and contractor employee qualifications is obtained and reviewed, the
IRS cannot assure the accuracy and allowability of the charges included on the
invoices/vouchers.
TIGTA
also identified two instances in which corrective actions were reported as
being completed even though all the questionable charges had not been
recovered. TIGTA brought this issue to
management’s attention and they agreed to resolve the issue. In addition, management agreed to change the
reporting process and to ensure that all agreed-to questionable charges are
recovered before they close the corrective action.
WHAT TIGTA RECOMMENDED
TIGTA
recommended that the Director, Procurement, provide training on the Guidebook
and follow up to ensure that it is being used to verify vouchers/invoices. Also, the Guidebook should be revised to
include a résumé review to ensure that contractor employees are qualified for
the positions at which they are being charged.
In
their response to the report, IRS officials agreed to the recommendation. Training on the Guidebook was provided to Procurement personnel in October
2007. Management plans to revise the Guidebook
to include a contractor employee qualification/verification process and to
implement a quality review process to monitor compliance. Also, management plans to discuss the
Guidebook at the 2008 Acquisition Planning Conference and make copies available
to all attendees.
