MPH FAFSA question

Hi everyone- So I'm applying to George Washington for my MPH, and recieved an e-mail that said: "Do you plan to apply for Financial Aid? If so, submit your FAFSA by the Priority Deadline (January 15) to receive your financial aid package in early April." I'm working on FAFSA now, but there's some information that I just don't see how I can fill out until I file taxes, which I'm not doing until about a week after the "priority deadline". Namely, the amount of income tax I'm paying in 2012. On one part of FAFSA, it said I could use information from 2011 if it was similar to 2012, but I wasn't working last year (still in school). Suggestions? Help? I want to have the best chance possible to get the financial aid I need, since GW costs and arm and a leg. (if I get in and decide to go there blah blah, just planning ahead). Thank you!
