<prompt> Human: I need to file taxes, but I dont even know where to begin. I have been kinda self-employed, working under the table, cash-only stuff. No 1099s or W2s floating around. Advice?Edit- Thank you for the replies.  <response>: IRS employee here:If you have filed a federal return in the last 10 years, you may be able to obtain any wage and income document W-2 and 1099 transcripts here at irs.gov.If that system wont work for you, you could make the same request using Form 4506-T When you have access to any wage and income transcripts, you can obtain prior revisions of the Form 1040 and instructions here Thank you for reading.
