How to Renew an Expired ITIN in 2026: Step-by-Step

How Do You Know If Your ITIN Has Expired?

2 independent triggers can expire your ITIN, and either one alone is sufficient. Before starting the renewal process, confirm which trigger applies to you.

The Three-Year Non-Use Rule

If your ITIN did not appear on a U.S. federal tax return (as the filer, spouse, or dependent) for tax years 2023, 2024, and 2025, the IRS automatically deactivated it at the end of 2025. Filing as a dependent on someone else's return also counts as use. Even one return in the three-year window keeps your ITIN active.

The Rolling Middle-Digit Schedule

The IRS retires ITINs in batches based on digits 4 and 5 of your number (format: 9XX-XX-XXXX). Even if you filed recently, your ITIN expires if your middle digits fall in a retired batch. The full schedule:

How to Verify Your ITIN Status

Call the IRS at 1-800-829-1040 with your ITIN and personal details. You can also review your filing history or check your original CP565 notice. A Certifying Acceptance Agent can check your status and start the renewal the same day. For the full ITIN expiration schedule, see our dedicated guide.

What Are the 5 Steps to Renew an Expired ITIN?

5 steps complete the renewal. The process uses Form W-7, the same form as a new application, but with fewer requirements. Under Rev Proc 2015-35, you do not need to attach a federal tax return for a standalone renewal.

What Documents Do You Need for ITIN Renewal?

The IRS accepts 13 documents for ITIN renewal, identical to new applications per IRS Publication 1915. In practice, 2 approaches cover nearly every applicant.

Option A: Passport Only

A valid, unexpired passport proves both identity and foreign status in 1 document. If you work with a CAA, they certify a copy so you never mail the original. This is the fastest path for 90%+ of applicants.

Option B: Two Documents from the IRS List

Without a passport, you need 2 from: national identification card, U.S. or foreign driver's license, birth certificate, foreign voter registration card, U.S. state ID, foreign military ID, U.S. visa, medical records (dependents under 6), or school records (dependents under 18).

All documents must be originals or certified copies from the issuing agency. Notarized copies are not accepted. If you mail originals, the IRS returns them within 60 days. See our complete ITIN documents checklist for the full list with requirements for each document type.

How Long Does ITIN Renewal Take in 2026?

6 to 11 weeks is the IRS processing window. This clock starts when the IRS receives your complete Form W-7, not when you mail it.

Processing Timeline Breakdown

Peak tax season (January through April) pushes processing toward 11 weeks. Off-season renewals often finish in 7 to 8 weeks. Submit before tax season to avoid refund delays. For real-time estimates, see our ITIN processing time tracker.

Can You File Taxes While Waiting for ITIN Renewal?

Yes. 2 options let you file without waiting for your renewal to complete.

Option 1: Submit Both Together

Mail Form W-7 and your tax return in the same envelope to the IRS ITIN Operations center. The IRS processes the renewal first, then applies credits to your return. This is the simplest approach if you are near the filing deadline.

Option 2: Renew First, File Later

Submit your W-7 renewal on its own, wait for the CP565 confirmation, then file your return with an active ITIN. This avoids refund processing delays but requires planning 9 to 14 weeks ahead.

Do not skip filing because your ITIN expired. The IRS accepts returns with expired ITINs but withholds credits until renewal completes. For non-residents, see our Form 1040-NR filing guide.

How Much Does ITIN Renewal Cost in 2026?

$0 is the IRS fee. Form W-7 is free on irs.gov, and there is no government processing fee. All costs come from document handling and professional preparation.

Can You Renew ITINs for Your Entire Family at Once?

Yes. The IRS allows renewal applications for your spouse and dependents in a single mailing. Each person needs their own Form W-7 and identity documents, but everything goes in 1 package.

Why Family Renewal Matters Financially

If you only renew your own ITIN but your spouse's or dependent's ITIN also expires, the IRS strips credits tied to those family members. The Child Tax Credit alone is worth up to $2,000 per qualifying child. For a family with 3 dependents, that is $6,000 in potential lost refund money. Renewing everyone at once prevents this.

Early Renewal Is Allowed

You do not need to wait until a family member's ITIN officially expires. The IRS accepts early renewals for anyone whose middle digits are in an upcoming batch. For applying ITINs for dependents, see our dedicated guide.

What If You Lost Your ITIN Number?

Your ITIN is permanently assigned. Losing the number does not mean you need a new one. 3 methods retrieve it.

Check Your Records

Look at copies of previous tax returns, IRS correspondence, or your original CP565 notice. Your ITIN appears on all of these. See our ITIN number lookup guide for more methods.

Call the IRS

Dial 1-800-829-1040 with your name, date of birth, and address on file. The agent can look up your ITIN and confirm its status.

Work with a CAA

A Certifying Acceptance Agent can help locate your ITIN and proceed directly to renewal, saving you hours on IRS phone lines.

How Do You Prevent Your ITIN from Expiring Again?

4 habits keep your ITIN active after renewal.

File at Least Once Every 3 Years

Even a zero-income return resets the three-year clock. Being listed as a spouse or dependent counts. This is the single most effective prevention method.

Track the Middle-Digit Schedule

The IRS publishes upcoming digit-group retirements annually. If your digits are next, renew proactively before the deadline.

Keep Your IRS Address Current

Update your address using Form 8822 so you receive CP48 expiration notices. The IRS only mails these to the last address on file.

Set a Calendar Reminder

Mark the end of the third year after your most recent filing. Check the ITIN status checker guide for verification methods.
