You can check the status of your Form 1040X.pdf using the Where's My Amended Return? (WMAR) online tool or the toll-free telephone number 866-464-2050 three weeks after you file your amended return. Both tools are available in English and Spanish and track the status of amended returns for the current year and up to three prior years.
You must enter your taxpayer identification number (usually your social security number), date of birth, and ZIP code in either tool to prove your identity. Once you authenticate, the web tool shows an illustrated graphic to visually communicate the status of your amended return within the processing stages: Received, Adjusted, or Completed. As a reminder, amended returns take up to 16 weeks to process and up to three weeks from the date of mailing to show up in our system. Before that time, there's no need to call the IRS unless the tool specifically tells you to do so.
