An ITIN (Individual Taxpayer Identification Number) is the key that lets many immigrants file taxes, open bank accounts and build credit without an SSN. But an ITIN can expire, and an expired one can delay refunds and complicate everything that depends on it. This guide explains when an ITIN expires, how to renew it, and how to avoid the mistakes that slow the process.
Does My ITIN Expire?
Yes, it can. The rule that applies to everyone is the three-year non-use rule: an ITIN expires if it isn’t used on a federal tax return for three consecutive years. According to one tax firm’s 2026 summary of the rules, it expires on December 31 of the third consecutive tax year it goes unused.
What counts as “use”? According to that same summary, filing your own federal return with the ITIN resets the clock, and being claimed as a dependent on someone else’s federal return also counts. Appearing on a Form 1099 or other information return does not.
Separately, in past years the IRS also expired ITINs in groups based on their middle digits, with notices in 2018 and 2019 listing different groups. According to that tax firm’s summary, that schedule has ended and no middle-digit group is scheduled to expire in 2026. Older ITINs that were never renewed may already be expired, so if yours was issued many years ago, verify its status with the IRS rather than assuming.
What Happens If Your ITIN Expires?
An expired ITIN does not stop you from filing. In the IRS’s 2018 guidance, returns filed with an expired ITIN were still processed, but certain credits and exemptions could be disallowed until the ITIN was renewed, and refunds could be delayed. After renewal, the credits and refunds were restored. The IRS recommended renewing before filing to avoid delays. Rules for specific credits change with tax law, so check the credit you expect to claim before you file.
ITIN Renewal at a Glance
| Question | Answer |
|---|---|
| Who needs to renew? | Anyone whose ITIN has expired and who needs to file a return or be claimed for a tax benefit |
| Which form? | Form W-7, marked as a renewal |
| Documents | Original documents or copies certified by the issuing agency |
| Where to apply | By mail, through a Certifying Acceptance Agent, or at an IRS Taxpayer Assistance Center by appointment |
| Documents returned | The IRS says it returns them within 60 days |
| Family | Family members can renew at the same time |
Step-by-Step: How to Renew
Step 1: Confirm you need to renew. Check whether you used your ITIN on a federal return in the last three years. If you didn’t, it has likely expired or is about to.
Step 2: Get the current Form W-7 and instructions from the IRS. Requirements, including whether a tax return must be attached with a renewal, have changed over time, so follow the current instructions rather than older guides.
Step 3: Gather your identification. The IRS accepts original documents or copies certified by the issuing agency. A current passport is the most commonly used document, but check the form’s list for your situation.
Step 4: Choose how to submit. You can mail your application to the IRS ITIN Operation in Austin, Texas, apply through a Certifying Acceptance Agent so you don’t have to mail your originals, or schedule an appointment at an IRS Taxpayer Assistance Center.
Step 5: Renew with your family if needed. According to the IRS, family members issued an ITIN can submit Forms W-7 at the same time. Spouses and dependents generally need to renew only if they will be claimed for a tax benefit or file their own return.
Step 6: Allow time and track your tax filing. Processing commonly takes several weeks and is slower during peak filing season. File early if you have a deadline.
Why Renewal Matters Beyond Taxes
Your ITIN is often the ID number tied to your financial life: your bank account, your secured card and, later, an ITIN mortgage. An expired ITIN can cause problems when a lender or bank verifies your tax history. Keeping it active protects the work you’ve done. See our step-by-step ITIN guide, our guide to the best credit cards for immigrants with no SSN and our guide to ITIN mortgages.
Common Mistakes to Avoid
Waiting until tax season. Processing is slower when everyone files at once. Renew earlier.
Mailing your only original passport without a plan. Consider a Certifying Acceptance Agent or an IRS appointment so you don’t have to part with your originals.
Sending incomplete documents. The IRS says applications missing required documentation are delayed until it receives them.
Assuming a dependent needs to renew. Renewal is generally tied to being claimed for a tax benefit or filing a return.
Using unlicensed “notarios” or paid shortcuts. The IRS process is the official route. Be careful with anyone who charges to “guarantee” a renewal.
Relying on old articles. ITIN rules have changed several times since 2016. Use the current IRS instructions.
Frequently Asked Questions
How do I know if my ITIN has expired?
If you haven’t used it on a federal return for three consecutive years, assume it may have expired, and confirm with the IRS or a Certifying Acceptance Agent.
Does renewing an ITIN change my number?
Renewal is intended to keep your existing ITIN active. Include your previous ITIN on the application as instructed.
Can I still file taxes with an expired ITIN?
Yes, but certain credits may be disallowed and refunds delayed until it’s renewed.
Does my immigration status matter for renewal?
The ITIN is a tax ID, not a work or immigration document. For questions about your status, consult a licensed immigration attorney.
Is there a fee?
The IRS does not charge a fee to apply. A Certifying Acceptance Agent or tax preparer may charge for their service.
