ITIN Renewal Rules: Avoid This Common Filing Problem
Many taxpayers don’t realize that ITINs expire—until the IRS delays their return or denies a credit.
If you file with an expired ITIN, it can lead to processing delays, lost credits, and IRS notices.
Here’s what you need to know to avoid problems.
Do ITINs Expire?
Yes it does.
An Individual Taxpayer Identification Number (ITIN) expires if it is not used on a federal tax return for three consecutive years.
Example:
If your ITIN was last used on a 2021 return and not used again, it may now be expired.
What Happens If You File With an Expired ITIN?
The IRS will still process your return—but with limitations.
You may experience:
- Delays in processing your tax return
- Denial of certain tax credits
- An IRS notice requesting renewal
What About Dependents’ ITINs?
If you claim dependents, their ITINs must also be valid.
If a dependent’s ITIN is expired:
- Credits like the Child Tax Credit may be denied
- You may receive an IRS notice
How Do You Renew an ITIN?
To renew an ITIN, file Form W-7 (Application for IRS Individual Taxpayer Identification Number).
You will also need:
- Supporting identification documents (such as a passport), or
- Certified copies from the issuing agency
When Should You Renew Your ITIN?
Best practice:
Renew before filing your tax return if you think your ITIN may be expired.
Why this matters:
- Prevents delays
- Preserves eligibility for credits
- Avoids IRS notices
Can You Renew an ITIN With Your Tax Return?
Yes—but it’s not ideal.
If you submit a renewal with your return:
- The IRS will process both together
- Your return will likely be delayed
Common ITIN Renewal Mistakes
- Waiting until after filing to renew
- Forgetting to renew dependents’ ITINs
- Submitting incomplete documentation
- Assuming the ITIN is still active
Key Takeaways
