Federal employees apparently owe some $2.8 billion in federal income taxes. Paul Caron at TaxProf reports that, measured in terms of the percentage of employees who are tax scofflaws, the worst agencies are the U.S. Commission on Civil Rights (9.43%), the Government Printing Office (7.41%), and the Smithsonian (5.56%). Also worth noting, apparently 4.85 percent of Tax Court employees are tax scofflaws as well.
