The IRS offers a dedicated online service called “Where’s My Amended Return?” (WMAR) for taxpayers to check the processing status of their amended tax returns. This tool tracks amended returns filed using Form 1040-X, Amended U.S. Individual Income Tax Return, which are used to correct errors or omissions on a previously filed tax return.

What is an Amended Tax Return?

An amended tax return allows you to correct mistakes or make changes to your original federal income tax return. Common reasons to file include:

  • Forgotten deductions or credits,
  • Math errors,
  • Receiving corrected W-2 or 1099 forms after filing,
  • Changes in life circumstances affecting tax liability (marriage, birth, property sales).

Filing Form 1040-X informs the IRS of these corrections and updates your tax account accordingly. Learn more about Form 1040-X on FinHelp’s glossary entry: Form 1040-X – Amended U.S. Individual Income Tax Return.

How Does the “Where’s My Amended Return?” Tool Work?

To track your amended return status, visit the official IRS page at Where’s My Amended Return?.

You will need:

  • Your Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN),
  • Your date of birth,
  • Your mailing ZIP code,
  • The tax year of the amended return.

Keep in mind:

  • The IRS recommends waiting at least three weeks after mailing your Form 1040-X before using the tool, as the processing system takes time to update.
  • Amended returns typically require manual processing, which can take up to 20 weeks or longer during peak periods.
  • The tool updates once a day, usually overnight, so daily checks are sufficient.

Statuses Displayed on the WMAR Tool

The tool generally shows one of these statuses:

Status Meaning
Received IRS has received your amended return.
Adjusted IRS processed your return and made changes.
Completed Processing is finished; refunds or balances updated.
No Record Found No record matches your input; check details or wait longer.
Call IRS IRS needs additional info; contact them.

Why Does Processing Take So Long?

Unlike original returns, which are often electronically filed and processed automatically, amended returns generally require manual review by IRS personnel. They verify your amendments against your original return, which adds to processing time.

Best Practices for Tracking Your Amended Return

  • Be patient and allow the full processing time.
  • Keep copies of your original return, Form 1040-X, and any supporting documents.
  • Check the status no more than once per day.
  • If the status doesn’t update after 24 weeks or if instructed, contact the IRS customer service for assistance.

Who Uses the WMAR Tool?

Primarily individual taxpayers correcting past tax returns, tax professionals managing clients’ amended returns, and those amending returns for up to three years from the original filing date.

Common Questions

  • Can I e-file Form 1040-X? Usually, no. Most amended returns must be mailed, but the IRS is gradually starting to accept e-file for certain years.
  • Can I track state amended returns here? No, this tool only tracks federal amended returns.
  • What does “No Record Found” mean? Double-check your entry and wait at least three weeks after mailing before checking.
