Topic 156 - Copy of Your Tax Return – How to Get One

If you need an actual copy of your return, you should complete and mail Form 4506 (PDF), Request for Copy of Tax Return along with a check or money order for $ 39.00 per tax year made payable to the "United States Treasury". Allow 60 calendar days to receive your copies.

Most needs for tax return information can be met with a tax return transcript or a tax account transcript, rather than an actual copy of the return. The tax return transcript shows information from the return as it was originally filed. A tax account transcript shows any later adjustments either the taxpayer or the IRS made after the tax return was filed. Transcripts are provided free of charge. These transcripts may be acceptable substitutes for an actual copy of the return by the Bureau of Citizenship and Immigration Services and lending agencies for student loans and mortgages. Check with your agency or lender to be sure.

You can obtain a transcript by calling (800)–829–1040 or by completing and mailing Form 4506-T (PDF), Request for Transcript of Tax Return, to the address listed in the instructions to request all types of transcript verification of non-filing, and wage/income information.

Transcripts will be mailed directly to you, and should be received within two weeks after the IRS gets your request. Transcripts can be mailed to a third party if you specify this on Form 4506–T. However, you must sign and date the form giving your consent for the disclosure.
