The IRS has added an online tool to their website that helps taxpayers and tax preparers track the status of their amended federal return for the current year and up to three prior years. The IRS look-up tool Where's My Amended Return can be used approximately 3 weeks after the amended return has been mailed in for processing to:
- Confirm that the IRS has received the amended return
- Check on the processing status of the amended return
- Get an estimated completion time for the completed processing of the return
To use the 'Where's My Amended Return' tool, you must enter the taxpayer's identification number or SSN, date of birth, and zip code used to file their most recent tax return. If amended returns for multiple years have been filed, each return can be selected individually from the results. The status of an amended return can also be determined approximately 3 weeks after it has been mailed by calling the IRS Where's My Amended Return line at 866.464.2050.
