Roughly one in nine Pentagon contractors illegally evaded taxes while holding contracts.

Evidence

In 2004, the Government Accountability Office found that 27,100 Pentagon contractors—about one in nine—were illegally evading taxes while still receiving money from government contracts. Privacy rules prevented the government from naming names, but in one case a contractor providing base services owed almost 10 million in taxes while receiving 3.5 million from the Pentagon. The government estimated the total taxes owed by military contractors at $3 billion. — David Vine, Base Nation_ How U.S. Military Bases…, 725
