<prompt> Human: Im very aware how much of an issue this is, but I am just trying to fix my procrastination. Where can I go to figure out what to fill out and what documents are necessary? Ive lived in three states so I believe Ill have to also file with each state right? I could probably hire a professional but I hear that can get expensive.All I know so far is to get my W-2 forms and bank statements from those four years. As for forms, Im lost.  <response>: Your best bet is to hire a professional that knows the ins-and-outs of the regulations and can help minimize your penalties.If your withholdings were enough to cover your tax liability, though, youre actually not in terrible shape as the fine is primarily based on unpaid taxes. You may even be due a refund, though at this point you can only claim refunds for 2011, 2012, and 2013. Heres some information from the IRS on past-due returns especially see the instructions for getting W2s and other income information from the IRS if you cant find them otherwise: You can use tax software to prepare your returns or download paper forms from the IRS websiteIf a state you livedworked in collects income tax, you should probably file with them, too. Different states will have different rules, though, so it could get a bit complicated. Just take it one step at a time and youll be fine.
