ITIN Renewal and Expiration: Has Yours Expired?
One rule decides it, and it takes thirty seconds to check. Here is the rule, the way to test your own number against it, and what a return filed with a lapsed ITIN actually costs you.
Every rule on this page is cited to an IRS source, linked where it is used. Last read against those sources September 9, 2026.
An ITIN expires if it does not appear on a U.S. federal tax return for three consecutive tax years — on December 31 after the third tax year of non-use. One return in three years keeps it alive. So an ITIN last used on the 2022 return and absent from the 2023, 2024, 2025 returns expires on December 31, 2026 — a year after 2025 ends, not at the end of it. Renewing means filing Form W-7 again, marked as a renewal, with your supporting documents and the federal tax return — unless a Form W-7 exception applies. Allow 7 weeks, or 9–11 in filing season, for the answer.
Key takeaways
- One return in three years is enough. You do not need to file every year to keep the number.
- A lapsed ITIN does not get your return rejected. It gets it delayed, and it can cost you credits while you wait.
- Information returns are carved out. If your number only appears on a Form 1099 reporting payments to you, no renewal is needed.
- A renewal travels with your tax return. The current W-7 instructions require a federal return with every renewal application unless a Form W-7 exception applies, so this is not something to file on its own ahead of the season.
- File early in the season rather than late. The same application takes several weeks longer inside the January 15 through April 30 window.
- Renew the whole household at once if more than one number on the return is lapsing.
The rule, in one sentence
That is the entire test. There is no expiry date printed on your CP565 notice, no online lookup, and no separate schedule to consult. The IRS is asking one question: has this number been used on a return recently enough to suggest it is still needed?

How to check whether yours has expired
- Look at the 2023, 2024 and 2025 federal returnsYour own returns, or a return somebody else filed that listed you as a spouse or dependent. Either counts.
- Ask whether your ITIN appears on at least one of themNot all three. One is enough. It can be any of the three.
- If the answer is yes, the number is currentNothing to do. Carry on.
- If the answer is no, it expires on December 31, 2026December 31 after the third tax year of non-use — a year after 2025 ends, because the 2025 return is not due until the following spring. Filing that return before the deadline still keeps the number alive. Otherwise renew it with the next return you file: the renewal application has to include that return unless a Form W-7 exception applies.

What happens if you file with an expired ITIN
This is the question worth having a straight answer to, because the fear — that the return is thrown out — is worse than the reality, and the reality is expensive enough on its own.
| What people fear | What actually happens |
|---|---|
| The return is rejected and I have not filed | It is not rejected. The return is accepted and processing is delayed while the number is sorted out. |
| I will be penalised for using an expired number | There is no penalty for the expired number itself. Penalties arise indirectly, if a disallowed credit leaves a balance due. |
| I lose the credits permanently | Credits that depend on the number can be disallowed until it is renewed. Renewing and, where needed, amending is the route back. |
| My refund disappears | It is delayed, and it can be reduced while credits sit disallowed. |
The IRS states the consequences in three parts:
- Your return still gets filed. It is not rejected outright, but processing is delayed.
- Credits that depend on the number can be disallowed until it is renewed, which cuts the refund.
- A reduced refund can turn into penalties and interest if it leaves a balance due.

In the following filing season they had income again and filed in early February — with the lapsed number, because nobody had told them it lapses. The return was accepted. The $500 Credit for Other Dependents claimed for their younger child was held back pending the number, and the refund came several months late and short.
The fix was a renewal filed with that return, marked as a renewal rather than as a new application — and because it went in during February, inside the January 15 through April 30window, it took the long 9-to-11-week route. They could not have renewed alone the previous autumn: the instructions require the return in the package. What they could have done is prepare the return in January and post the package in the first week of February rather than the last, and check the three-year rule before the season rather than during it.
How to renew
A renewal is the same Form W-7 as a new application, marked as a renewal, with the same document standard.
- Complete Form W-7 and mark it as a renewalNot a new application. Marking a renewal as new creates a duplicate record instead of reviving your history, and the IRS then has to unpick it.
- Enter the ITIN you are renewingThe number itself, exactly as issued. It is on your CP565 notice and on any return you filed with it.
- Attach your supporting documentsOriginals or copies certified by the agency that issued them — the same standard as a new application, and notarised copies are not accepted here either. A valid passport still covers both columns on its own.
- Attach the federal tax returnA Form W-7 renewal application must include a U.S. federal tax return, unless you meet one of the Form W-7 exceptions — in which case that exception's own evidence goes in instead, exactly as it would on a first application. A spouse or dependent renewing in order to be claimed for a tax benefit is listed on that same return — the benefit is what justifies the number, so the IRS wants to see it.
- Submit by any of the three routesMail to ITIN Operation, P.O. Box 149342, Austin, TX 78714-9342, or use an IRS Taxpayer Assistance Center or a Certifying Acceptance Agent. Same routes, same trade-offs as a new application — see the W-7 guide.

Timing: what you can and cannot control
The processing windows are the same as for a new application. What differs is your freedom to choose the moment, because the renewal has to travel with a return.
- You submitweek 0
W-7, the tax return it is attached to, and your documents leave your hands.
- Receipt and sortingweeks 1–3
The ITIN Operation logs the package. Nothing is visible to you during this stage.
- Document reviewweeks 3–6
An examiner checks the documents against the reason code you claimed. Anything missing produces a CP566 request for more information, which restarts the clock.
- Decisionweeks 6–7
A CP565 assigns the number, or a CP567 rejects the application.
- Documents returnedweeks 7–11
Originals are mailed back. Peak season and overseas applications sit at the long end of every stage above.

Applying between January 15 through April 30 puts you in the queue with every new applicant of the filing season. Because the return has to be in the package, the renewal happens when you file rather than at a moment of your choosing. The lever you do control is when you file: the same application takes several weeks longer inside the peak window than outside it.So the practical move is not “renew in the autumn” — the return has to be in the package — but to have the return ready and get the package in as early in the season as you can, rather than in the last fortnight before the deadline when the queue is longest.
The old middle-digit schedule, and why it no longer applies
For several years the IRS ran a rolling programme that retired ITINs by their fourth and fifth digits — one block of middle digits each year — alongside the non-use rule. A great deal of material online still describes that schedule and tells you to check your middle digits against a table.
That programme ran its course. What governs now is the three-year non-use rule, and that is the only test on this page. If a guide asks you to look up your middle digits to find your expiry year, check its date before you act on anything else it says.
The middle digits still matter for one thing, and only one: recognising that a number is an ITIN at all rather than a Social Security number. That test is on ITIN vs SSN.
Frequently asked questions
Does an ITIN expire?
Yes. If an ITIN is not used on a U.S. federal tax return for any three consecutive tax years, it expires on December 31 after the third tax year of non-use. One return in three years is enough to keep it alive — you do not need to file every year, only at least once in any rolling three-year window.
How do I know if my ITIN has expired?
Check three consecutive tax years. If your ITIN appeared on at least one filed federal return for 2023, 2024, 2025, it is current. If it appeared on none of them, it expires on December 31, 2026 — December 31 after the third tax year of non-use, which is a year later than people expect because the 2025 return is not due until the following spring. There is no online lookup and no expiry date printed on the CP565 notice — the three-year test is the whole rule.
Do I need to attach a tax return to renew my ITIN?
Yes, in the ordinary case. The current Instructions for Form W-7 say that all Form W-7 renewal applications must include a U.S. federal tax return unless you meet one of the Form W-7 exceptions — and if an exception applies, that exception's own evidence goes in instead, exactly as it would on a first application. So a renewal is not something you can generally file ahead of filing season on its own: it travels with the return, the same way a new application does.
What happens if I file with an expired ITIN?
Your return is still accepted, but processing is delayed. Certain credits can be disallowed until the number is renewed, which reduces your refund, and a reduced refund can leave a balance due that attracts penalties and interest. The return is not rejected outright — it just gets slower and can get more expensive.
Do I have to renew an ITIN that only appears on a Form 1099?
No. If your ITIN is only being used on information returns filed with the IRS by third parties — a Form 1099, for instance — you do not have to renew it for the purpose of filing a U.S. federal tax return, even though it has expired. This is a genuine carve-out worth knowing about: if a bank or a payer has your ITIN on file for reporting purposes and you have no filing obligation, an expired number is not a problem for that use.
What about the old middle-digit expiration schedule?
Older articles describe the IRS retiring blocks of ITINs by their fourth and fifth digits year by year. That rolling programme ran its course. What governs now is the three-year non-use rule. If you are reading a guide that tells you to check your middle digits against a schedule, it is out of date.
How long does an ITIN renewal take?
The same windows as a new application: allow 7 weeks to be notified of the outcome, or 9 to 11 weeks between January 15 through April 30 or from abroad. Because the renewal has to travel with your return, the lever you control is when you file rather than when you renew — filing early in the season, or on a return you are able to file before the rush, is what keeps you out of the long window.
Can my whole family renew together?
Yes, and it is worth doing. If one person in the household has to renew, everyone on the return with an expiring number can be renewed at the same time in the same package, rather than discovering the second lapsed number after the first renewal is already in the post.
