<prompt> Human: Im an international student doing my post grad in the US. I was a teaching assistant for a semester last year, and earned a total of 2000 over four months.I kept delaying paying taxes coz of studies and now Im nearing the deadline and panicking. Am I screwed? Will the late fee be massive if my forms reach the big guys after the 14th? Will this have implications when Im looking for jobs later this year? Any help will be really helpful, thanks!Edit: I just looked at my previous receipts. They have cut federal tax and state tax from my salary. So that means I just need to file returns. Do I need to though?  <response>: If you only earned 2000 in a year then theres no federal income tax - if federal income tax was taken out of your paycheck, then you ought to file to get a refund. As far as I know theres never a penalty for late filing if youre getting a refund.That said, I think it could potentially be possible that you owe state income tax. The penalty in that case would depend on the state, but ought to be very small, since penalties for this sort of thing tend to be proportional to the amount owed.
