How to File a Pennsylvania Tax Amendment

On eFile.com, you can prepare a Pennsylvania Tax Amendment for the 2024 tax year, but it cannot be submitted electronically. Once you have completed the amendment process, download the PDF from your My Account section, mark the appropriate box, and send the form to the address provided on this page. For other tax years, fill out the form before printing, signing, and mailing it in.

If you need to file a federal amendment, the IRS requires a different Form - Form 1040X - to amend an IRS return (do not use Form 1040 for an IRS Amendment).

If the IRS identifies an error on your tax return or if you discover one yourself, you may receive a notification from the IRS to make changes. When either you or the IRS amends or alters one of your federal tax returns, the IRS notifies the Pennsylvania Tax Agency. Therefore, it's important to file a Pennsylvania Tax Amendment within one year of any amendments made to your IRS Tax Return.
