I just did an audit of my retirement pay and noticed that my VA compensation was lowered. Did some research and found that not only was my pay lowered just recently, it had been miscalculated for a very long time. Now I have several questions. How far back can I go to get my benefits corrected? It isn't really back pay, as it is a change in my taxable income as I am rated at 30 %, but the tax advantage should change what I have paid in taxes for those years. Next question is how do I get amended tax information from DFAS to provide to the IRS? Anybody go thru this before? Thanks and Semper Fi! Mike
