Filing an amended tax return using Form 1040-X can be a big relief when you realize a mistake or omission on your original tax return. But after sending in your amended return, one pressing question almost always comes up: How long until I get my refund or see the changes reflected?

The 16-Week Waiting Period: What to Expect
The IRS states that processing an amended return typically takes 8 to 12 weeks, but it can sometimes extend up to 16 weeks or more. This longer timeline happens because the IRS must carefully review your changes, verify supporting documentation, and adjust your tax account accordingly.
Unlike original returns, amended returns are processed manually by IRS employees rather than automated systems, which contributes to the extended wait time.
How to Track Your Amended Return
To ease the wait, the IRS provides a handy online tool called “Where’s My Amended Return?” accessible on the IRS website. This tool becomes available about 3 weeks after you file your amended return.
You can check your status based on three processing stages:
- Received: IRS has your amended return but hasn’t begun reviewing it yet.
- Adjusted: IRS has reviewed and made changes to your return.
- Completed: Processing is finished, and any refund or payment adjustments have been made.
You’ll need to enter your Social Security number, date of birth, and zip code to use this service.
What Causes Delays Beyond 16 Weeks?
While the IRS aims to process amended returns within 16 weeks, delays can happen due to:
- Errors or missing documentation on your amended return
- High volume of filings during peak seasons
- Identity verification issues or suspected fraud
- Complex tax situations or multiple amendments
- COVID-19 related staffing or system impacts (less likely but still possible)
Tips to Speed Things Up
- Make sure your amended return is complete and accurate before filing.
- Include copies of all necessary forms and schedules related to your changes.
- Use the IRS online tracking tool, and avoid calling before 3 weeks have passed.
- Respond quickly if the IRS contacts you for additional information.
Filing a Form 1040-X is your best way to fix mistakes and get any additional refunds you deserve, but patience is crucial during the 16-week IRS processing window. Use the online tools provided to track progress, and stay organized with your tax documents in case you need to provide more information.
With the right approach, you’ll navigate the amended return process smoothly and confidently.
