I left me previous employer (DoD) on 21 Oct 11. Erroneously, they paid me two more times after I left. In mid-December, the Defense Finance and Accounting Service (DFAS) sent me a letter telling me how to go about paying the two over payments back. The problem is they said I owed them more back than I received in net pay. To make a long story short, it took DFAS a month to provide me an explanation on the difference - the explanation was marginal at best, but I went ahead and paid them the full amount in mid-January. When I received my W-2 from DoD at the end of January, it still showed the two over payments as salary. When I contacted them about receiving a corrected W-2, they said I would receive a corrected W-2 next January, which means their error goes unchecked and my tax burden goes up through no fault of my own. And yes, I just prepared my taxes for 2011, and these two over payments threw me into a higher tax bracket, increasing what I owe on federal and state by an additional $2,500. DFAS doesn't seem interested in doing anything about it now - their solution is to just issue me a revised W-2 next January. What are my legal options?
