How Long Will It Take for My Tax Amendment to Process?

Once you have mailed in your federal tax amendment form 1040X, it will take between 8 to 12 weeks from the IRS receipt date until the form is processed. You can check the status of your amended return on the IRS "Where's My Amended Return" tool. This tool is available by calling 1-866-464-2050 or by visiting the IRS website.

It generally takes the IRS 8-12 weeks to process an amended return, so you should wait at least 8 weeks before checking on the status of your new amended tax refund. Once your amended return has been processed, you will receive any additional refund you are owed.

If it has been over 12 weeks and you still have not received your amended refund check, you can find more information about your refund by calling the IRS customer support line at 1-800-829-1040.

The IRS may review your amended return and situation more carefully, especially if the amended return reports a considerable amount of money back. As an alternative, you may apply part or all of your refund to your current year's tax. 

What If I'm Expecting My Original Tax Refund, But I Have Not Received It Yet?

You should wait until you receive the tax refund before you amend your tax return. This allows for any changes or corrections the IRS may have made to your return.
