<prompt> Human: Ok, I know Im going to get roasted for this but I need some advice. I havent paid taxes for the past 5 years. Ive googled the situation and am truly unsure of what I need to do. Contact the IRS? Contact a debt relief company? Like I said, I know Ill probably get tons of comments about how dumb I am and thats ok. Ive just now gotten back on my feet financially and I want to take care of this huge, looming cloud that is constantly over me. So, by all means, call me stupid then follow it up with some advice.  <response>: Okay, I am not a tax attorney, but I clerked for a Federal District Judge which hear appeals from the Tax Court and saw a similar case.A. You have to pay it off. The fees and interest on late taxes can be found here There are failure to file and failure to pay penalties. B. Stuff to know: Are there any facts you are not telling us? 1 There are medical exceptions rare, that require a burden of production and proof. For this medical exception you must provide substantial evidence, ie, you cant just BS.2 Did you request extensions? Overall, I would suggest getting a lawyer,. The attorney may find facts that can help you. Obviously, balance this with how much you think you owe see the website above. If you call the IRS, you will be on the record, admitting to not paying. Edit: If you also owe statelocal taxes, you need to figure that out as well.
