My ex filed social security/disability and my son receives a monthly check from social security administration. He is a junior in high school but my daughter is a freshman in college. I have seen some posts say that I have to claim the monthly payment as untaxed other income and some say that I don't claim it at all because it is under my son's SSN. Has anyone found which is the true answer? This question applies to government aid as well as university aid so any input will be much appreciated. Thanks!
