<prompt> Human: Im 46 and havent filed for federal or state taxes since the early 90s. For many of those years I was marginally employed, waiting tables, or unemployed. Things are better now. Ive worked at the same job for over three years and Ive been making steps to enter the adult world. However the tax issue is a big monkey on my back.Ive been told that the fact that I havent been audited means Ive probably been leaving money on the table as the IRS would have come after me if I owed any significant amount. I know I can only get refunds for the last three years. Do I file for the last three years and see what happens with the IRS for the previous 17 or so?  <response>: Ask in rtax All the cool people from the IRS are over there. Dont worry they wont send a raiding party to your house if you ask a question.
