ITIN Renewal: How to Tell If Yours Has Expired and the Exact Steps to Reactivate It

The IRS does not send a reminder to most ITIN holders before their number expires. It also does not bounce a tax return that uses an expired ITIN — the return enters processing, but credits and refunds tied to the ITIN are held until the renewal is complete. The result is that many ITIN holders discover their number is expired only after filing, often three to six months into a refund cycle that has stalled.

This guide explains the single expiration rule that is currently active, how to check your status before you file, and the renewal procedure that — unlike the initial application — does not require a tax return.

The one live expiration rule: three-year non-use

The IRS expiration guidance is precise:

"If an ITIN isn't used on a U.S. federal tax return for any 3 consecutive tax years, it expires on December 31 after the third tax year of non-use."

Source: IRS — ITIN Expiration FAQs.

The rule is cumulative and forgiving. Filing a return that carries your ITIN for any one year resets the clock. The clock only runs if you have filed nothing using that ITIN for three consecutive tax years.

Worked example. For an ITIN holder evaluating their status in 2026:

• If you filed a 1040 or 1040-NR carrying your ITIN at any point in tax years 2023, 2024, or 2025, your ITIN is active. The clock starts again from your last use.
• If you have not filed any return using your ITIN in 2022, 2023, or 2024, your ITIN expired on 31 December 2025. You need to renew before the next time you use it.
• If your last use was in 2021 or earlier, your ITIN has been expired for at least a year — and possibly longer, depending on when the last return was filed.

This is the only ongoing expiration rule. The middle-digit-based expiration schedule from the PATH Act (2016–2020) is historical: every middle-digit batch under that programme expired between 2016 and 2020. After 2020, no new middle-digit-based expirations are issued. If your ITIN was on the historical PATH Act middle-digit schedule and has not been renewed since, it has been expired for several years already.

How to check your status before filing

Three methods, in order of speed:

1. The math. Look at your last filed US tax return. If the return was for tax year 2022 or earlier and you have not filed since, your ITIN is expired.
2. Call the IRS ITIN line. US callers: 800-908-9982. International callers: 267-941-1000. Hours are Monday to Friday, 9:00 a.m. to 9:00 p.m. Eastern Time. Be prepared to verify your identity — name, ITIN, date of birth, country of citizenship.
3. Look for IRS Notice CP-48. If the IRS mailed a CP-48 notice to your address on file, your ITIN is or will be expiring. The notice arrives in advance of the expiration date for some taxpayers; for others it arrives after the fact. Either way, receiving CP-48 is a direct signal to renew.

If you have moved since your last US filing, the CP-48 notice — and the CP565 you originally received — may have gone to an old address. The IRS does not forward these. Calling the ITIN line is the only reliable way to confirm status if your mail is uncertain.

What happens when you file with an expired ITIN

The IRS guidance is explicit:

"You may not be able to claim certain credits unless your ITIN is renewed. This may result in a reduced refund or penalties and interest."

In practice this means:

• The return is accepted by the IRS — it enters processing, it is not rejected outright.
• Any credits or refund computed against the ITIN are held.
• The IRS sends a notice (often CP-48 retroactively, or a more specific letter) requesting renewal before the credits are applied.
• Once the renewal completes, the held credits are released and any refund is paid — sometimes with statutory interest, depending on how long the hold lasted.

The economic loss is therefore mostly a timing loss: the credits do not disappear, but they are unavailable until the renewal clears. For families relying on a Child Tax Credit, a six-month delay matters. For investors expecting a treaty-rate refund of over-withholding, the delay can run a year.

The renewal procedure

Renewal uses the same Form W-7 as a new application, with three procedural differences:

1. Tick the renewal box

At the top of Form W-7, the IRS provides a box marked "Renew an existing ITIN." Tick this box. Then enter your existing ITIN in the field that asks for it. This tells the IRS to look up your prior record rather than open a new file.

2. No tax return required

For a new ITIN application, the IRS expects Form W-7 to be attached to the related tax return (with limited exceptions). For a renewal, Form W-7 can be filed standalone — no return is required.

You can still attach a return if you have one ready. The IRS will process both together, which can shave a few weeks off the overall timeline if your filing deadline is near. But standalone renewal is the default path and is appropriate whenever you are renewing in advance of, rather than alongside, a specific filing.

3. Identity documents required again

Same as the initial application: a valid, unexpired passport (verified online by a CAA) or, in narrow cases, an approved combination of supporting documents. The IRS does not allow renewals to rely on the original certification — you produce a fresh certification with the renewal package.

This is where engaging a Certified Acceptance Agent simplifies the process: the CAA verifies your passport over a recorded video call, issues a Certificate of Accuracy, and packages the renewal for submission. Your passport never leaves your hands.

The full renewal package

Assembled in order:

1. Form W-7 with the "Renew an existing ITIN" box ticked and your existing ITIN entered.
2. Certified passport copy from the CAA verification, with the Certificate of Accuracy attached.
3. A brief cover letter noting that the application is a renewal and listing the contents.
4. Any optional supporting items — for example, a copy of an upcoming W-8BEN that triggered the renewal need, or the related tax return if you choose to file together.

The package is mailed to:

Internal Revenue Service ITIN Operation P.O. Box 149342 Austin, TX 78714-9342

We send via tracked international or domestic mail so the delivery date is on record.

Processing time

The IRS's published guidance is: "Allow 7 weeks for us to notify you about your ITIN application status" for routine applications.

In practice, recent application volumes during peak tax season (January through April) have pushed effective processing toward the 9–11 week range for renewals filed during that period. Renewals filed outside peak season tend to clear within the published 7-week window.

If the renewal is filed alongside a tax return that has a refund tied to the ITIN, the IRS typically processes the renewal first and then releases the held refund — adding the refund cycle on top of the renewal cycle.

After renewal: what arrives

The IRS mails a CP565 notice confirming the renewal. The notice shows:

• Your name and address.
• Your ITIN (the same number you previously held).
• The active status of the ITIN.

Keep the CP565 with your tax records. It is the proof of renewal status if a future filing is questioned. If you receive your CP565 at a US receiving address (for example, a service provider's address used during the renewal), forward a scan to yourself for permanent record.

Family renewals — keeping ITINs in sync

If multiple family members hold ITINs that have lapsed together — for example, a non-resident spouse and one or two non-resident dependents — renewing them in one package avoids the timing mismatch that would otherwise occur. Each family member's W-7 (renewal box ticked) goes into a single envelope, with each member's identity documents, and a single cover letter referencing the family relationship.

The IRS processes each W-7 individually but typically completes a batch from the same envelope within the same week. This matters when the next return is a joint filing or claims the dependents — having all the ITINs active before the return is filed prevents the credit-holding scenario described above.

Renewing when an SSN has been issued

A non-resident who received an SSN after holding an ITIN does not renew the ITIN. The SSN supersedes the ITIN for all federal tax purposes. The correct action is:

1. Write to the IRS ITIN Operation at the Austin address with your name, prior ITIN, and new SSN.
2. Stop using the prior ITIN on any forms — all future filings reference the SSN.
3. The IRS consolidates your records so any prior tax history under the ITIN is linked to the SSN.

If you are unsure whether your SSN application is final, do not start the ITIN renewal yet. Wait for the SSN issuance, then process the consolidation letter.
