<prompt> Human: A few years ago, I started working for a guy in California as basically an IT consultant - though it was really an employeremployee relationship. He pays me 4,000 a month 48k a year which is paid to me primarily in direct bank wires. I have not filed tax returns for the past three years 2010 - 2013. I have absolutely no records or documentation whatsoever, except for bank statements. I know I will almost certainly need to contact a tax professional, but Im wondering how they will handle this situation given that I dont have any W2s, etc. I also dont have a business license or anything like that. So I guess what Im asking is how would they go about approaching this situation, what will happen to me if I suddenly file three years worth of tax returns without any documentation i.e. will I be prosecuted?, and any other recommendations you might have. To those of you who have read all the above and have some genuine insight to offer, thank you in advance! I do feel incredibly guilty and ashamed about what Ive done, and I just want to fix this situation and move on with my life.  <response>: IRS employee here:Based on your description, the payer was probably treating you as a contractor, and should have provided a Form 1099-MISC listing your total non-employee compensation for each year. If they were reported to the IRS, you might be able to obtain transcripts of these documents here at irs.gov. You will be asked to provide ID verification information from your last return. If you cant pass the online verification, make the request in writing on Form 4506-TOnce you have your wage and income document statements, I suggest you speak with a trusted tax professional and prepare the returns. Provide any documentation and receipts for expenses you are able to locate for each tax year.Assuming you were treated as a contractor, you will be liable for income tax on your total income less any exemptions and deductions, as well as Self Employment tax. Since you are filing late and made no estimated tax payments, its likely you will owe a balance due for all three tax years. File the returns as soon as possible, and pay the tax liabilities in full when you file. After we process your returns, you will be sent a notice for each tax year asking for payment of the Failure to File penalty FTF, Failure to Pay penalty FTP, underpayment of Estimated Tax ES penalty, and interest backdated to the return due date for each year. Full pay those balances as the notices arrive, and you are done.Your tax professional should be able to provide a plan moving forward, if you continue to work as a Self Employed person.Thank you for reading.
