DOD and IRS records showed that over 27,000 contractors owed about $3 billion in unpaid taxes as of September 30, 2002. DOD has not fully implemented provisions of the Debt Collection Improvement Act of 1996 that would assist IRS in levying up to 15 percent of each contract payment to offset a DOD contractor´s federal tax debt. We estimate that DOD could have collected at least $100 million in fiscal year 2002 had it and IRS fully utilized the levy process authorized by the Taxpayer Relief Act of 1997. As of September 2003, DOD had collected only about $687,000 in part because DOD provides contractor payment information from only 1 of its 16 payment systems to TOP. DOD had no formal plans at the completion of our work to provide payment information from its other 15 payment systems to TOP.

Furthermore, we found abusive or potentially criminal activity related to the federal tax system through our audit and investigation of 47 DOD contractors. The 47 contractors provided a variety of goods and services, including parts or support for weapons and other sensitive military programs. The businesses in these case studies owed primarily payroll taxes with some dating back to the early 1990s. These payroll taxes included amounts withheld from employee wages for Social Security, Medicare, and individual income taxes. However, rather than fulfill their role as “trustees’ and forward these amounts to IRS, these DOD contractors diverted the money for personal gain or to fund the business.
