The “Where’s My Amended Return?” tool provides the status of Form 1040X Amended Tax Return for the current year and up to three prior years.
You can generally expect your amended return to be processed up to 16 weeks from the date we receive it. It can take up to three weeks from the date you mailed it to show up in our system.
Please Note: You will not be able to access certain amended returns using this application.
IRS telephone assistors will not be able to provide additional information while your amended return moves through processing.
There is no need to call our toll-free number unless “Where’s My Amended Return?” specifically indicates that you should call.
