i was told at most interviews to submit your FAFSA based on last years tax info and when you have your taxes done to go in and make the proper changes. From what I've gathered, most schools give their aid out on a first come first serve basis and as long as you submit your form early, you will be considered even if you have to make some changes later on. I will be attending Maryland and they have a March 1st priority deadline in order to be eligible for "all available financial aid".
