You can check the status of your amended tax return using the IRS's online tool called "Where's My Amended Return?" This tool becomes available about three weeks after you submit your Form 1040-X and generally shows updates for up to 16 weeks, which is the typical processing time for amended returns

. To use the tool, you will need:

• Your Social Security number or individual tax ID number
• Your date of birth
• Your ZIP code from the tax return

The tool is available 24/7 except for brief maintenance windows on Mondays (12 a.m. to 3 a.m. ET) and some Sundays (1 a.m. to 7 a.m. ET)

. Alternatively, you can call the IRS amended return hotline at 866-464-2050 to check your status using the same information

. The status you may see includes:

• Received: IRS has your amended return and is processing it
• Adjusted: IRS has reviewed and adjusted your account, which may result in a refund, balance due, or no change
• Completed: Processing is finished, and you will receive details by mail

Note that this tool does not cover business returns, foreign addresses, or certain special cases, and you should only call the IRS if the tool directs you to do so

. In summary, to find your amended tax return status, visit the IRS "Where's My Amended Return?" website or call 866-464-2050 with your SSN, birth date, and ZIP code, starting about three weeks after filing
