They look at the last return on file
So if your 2019 puts you over the threshold but your 2020 was lower, get it filed.
In any case, AGI from a tax return is such a 17ing stupid way to determine need.
A trust fund baby living off inheritance with little AGI is going to get a check, but a recent grad who nets 80k but may be drowning in student loan debt, medical expenses, taking care of elderly parents, etc. is above their arbitrary limit.
Good work Congress. At 75k you need it, but at 80k you don’t. Nevermind that they might’ve made that last year but got laid off in December. Sorry, but I have a client in this situation. Rant over.
