Reply #2: You can go to prison. It's pretty much vanishingly likely, though.

The biggest problem is that your name may get flagged and you could have trouble getting a job if you need one, since it's all tied to your SS#.

If you're in the position you say you're in, you probably don't own any tax at the end of the year, but are probably entitled to a refund. If you have a W2, then you're apparently employed. If you're employed and you have a W2, taxes have already been withheld from your paycheck. The IRS isn't looking for such as yourself, most likely. If you don't file, you'll get no refund.
