If you need a copy of your last year’s tax return you can get that information a number of ways.
First check with your last year’s tax preparer or login to your tax software you used. Most tax preparers can provide you a copy of a tax return that you prepared with them. In the same way, if you prepared your taxes yourself using a software program, you can usually download a copy by logging back into your account.
If you cannot reach out to your last year tax preparer or getting a copy from them or the software company is not an option, you can contact the IRS and request a free “transcript” of your tax return. The document that you can get from the IRS has most of the information that would be on the tax return you submitted to the IRS. This may be done online (https://www.irs.gov/individuals/get-transcript) or by using the IRS’ automated phone service at 800-908-9946.You need to request the “Return Transcript” and you can get it sent electronically or by physical mail.
If you need an exact copy of your tax return and documents, the IRS can provide that to you. You will need to file a form 4506 with the IRS and the IRS does charge a small fee to have this packet mailed to you.
