Alright, so I am currently going to school full time and I have been using my housing allowance that I receive from my Post 9/11 GI Bill to calculate Child support payments. I also work a part time job and make a little extra there. I was told that since my Housing allowance is a non-taxable income, that I can't file in my taxes, then it cannot be used towards configuring my child support payments. Is this true?
