ITIN reactivation and ITIN renewal are the same process. The IRS has no separate reactivation form, no special fee, and no alternative procedure. You submit Form W-7 with the "Renew" box checked, include your identity documents, and the IRS restores your original ITIN number. The IRS fee is $0 under Rev Proc 2015-35. Processing takes 6 to 11 weeks. This guide covers the full process, including documents, timeline, cost, and how to file taxes while waiting. Whether you need to reactivate an expired number or get your ITIN for the first time, our CAA-certified team can help.

ITIN reactivation and ITIN renewal are the same process: the IRS has no separate reactivation form, fee, or procedure. Whether your number lapsed a month or several years ago, you restore it by filing Form W-7 with the renewal box checked and your identity documents, and you get your original ITIN back. The fee is $0 under Rev Proc 2015-35, and processing takes roughly 7 to 11 weeks. This guide covers when reactivation is needed, the documents required, the timeline and cost, and how to file taxes while you wait.

Are ITIN Reactivation and Renewal the Same Thing?

Yes. The IRS treats them identically. There is no distinct reactivation form, no special fee, and no alternative procedure. Whether your ITIN expired last month or 5 years ago, you restore it by filing Form W-7 with the renewal box checked. The IRS uses "renewal" in all official communications. "Reactivation" is the common term taxpayers and professionals use for restoring a long-expired ITIN.

When Does Your ITIN Need Reactivation?

2 independent triggers expire your ITIN.

Three-Year Non-Use

If your ITIN was not on any federal return for tax years 2023, 2024, and 2025, it expired at end of 2025. Filing as filer, spouse, or dependent counts. Even 1 return in the window prevents expiration.

Middle-Digit Schedule

ITINs with middle digits 70-84 are already expired. Digits 85, 86, 87 expire December 31, 2026. This operates independently from non-use. See the full ITIN expiration schedule.

Call 1-800-829-1040 to verify your status. A Certifying Acceptance Agent can check and begin renewal the same day.

What Are the 4 Steps to Reactivate Your ITIN?

4 steps complete the process. Identical to a standard renewal.

Step 1: Complete Form W-7

Download Form W-7 from irs.gov. Check "Renewal of existing ITIN." Enter your ITIN. Match your name, address, and DOB to IRS records.

Step 2: Gather Identity Documents

1 passport or 2 from the IRS-approved list of 13 documents. Originals or agency-certified copies only.

Step 3: Choose Submission Method

Mail to IRS Austin, TX; visit a TAC in person; or use a CAA who certifies copies so you keep your passport.

Step 4: Wait for CP565 Confirmation

6 to 11 weeks. Your same ITIN number is restored. Track at itin.so/itin-application-status.

What Documents Do You Need for Reactivation?

13 documents accepted. 2 practical approaches.

Passport Only (Fastest)

Proves both identity and foreign status. With a CAA, you never mail the original. 90%+ of applicants use this path.

Two Documents from IRS List

National ID + birth certificate, driver's license + visa, or other combinations. See the complete checklist. Mailing originals means 60+ days without your documents.

How Long Does ITIN Reactivation Take?

Phase	Estimated Time
Document preparation (CAA)	2 to 10 business days
Postal delivery to IRS	5 to 10 business days
IRS processing	6 to 11 weeks
CP565 confirmation mailed	1 to 2 weeks
Total (end to end)	9 to 14 weeks

Peak season pushes toward 11+ weeks. Off-peak: 6-8 weeks. See processing time tracker and processing time by month.

Can You File Taxes While Reactivation Is Pending?

Yes. 2 paths forward.

Path 1: File and Renew Together

Attach Form W-7 to your return. Mail together. IRS processes renewal first, then applies credits. Recommended during tax season.

Path 2: File with Expired ITIN

The IRS accepts the return but strips credits. Once renewal completes, credits are applied retroactively. Longer wait for full refund.

Do not skip filing. File on time to avoid penalties. See Form 1040-NR guide for non-resident filing and expired ITIN renewal guide.

How Much Does ITIN Reactivation Cost?

$0 IRS fee. All costs are preparation and submission.

Method	Cost	Passport Mailing
DIY	$0 + postage	Required
itin.so Standard	$197	Not required
itin.so Express	$297	Not required
CPA firms	$300-$500+	Varies

See ITIN cost guide and service comparison.

How Do You Prevent Future ITIN Deactivation?

4 habits keep your ITIN active after reactivation.

File Every 3 Years

Even a zero-income return resets the clock. Being listed as a spouse or dependent counts.

Track the Middle-Digit Schedule

Renew proactively before your digits are retired. No penalty for early renewal.

Keep Your IRS Address Current

File Form 8822 after any move. CP48 notices go to last address on file.

Set Annual Reminders

Check your status in January each year. See who needs to renew and expiration guide.

ITIN Reactivation: Frequently Asked Questions

Is ITIN reactivation the same as ITIN renewal?

Yes. The IRS has no separate reactivation process. Whether your ITIN expired 1 month or 5 years ago, you restore it by filing Form W-7 with the renewal box checked. You receive your same ITIN number back. The terms reactivation and renewal are interchangeable. The IRS uses 'renewal' in all official communications.

How long does ITIN reactivation take in 2026?

IRS processing takes 6 to 11 weeks after receiving your Form W-7. Add 2 to 10 business days for preparation (depending on Standard vs Express service) and 5 to 10 days for postal delivery. Total end-to-end: 8 to 14 weeks. Peak tax season (January through April) pushes toward 11 weeks. Off-peak renewals often finish in 6 to 8 weeks.

Can I file taxes while my ITIN reactivation is pending?

Yes. You can submit your return with the expired ITIN or attach Form W-7 to your return and mail both together. If mailed together, the IRS processes the reactivation first, then applies credits retroactively. If filed separately with an expired ITIN, the IRS strips credits until renewal completes, then adjusts your refund.

Do I get a new ITIN number after reactivation?

No. The IRS reactivates your original ITIN number. All prior tax records remain linked to it. You receive a CP565 notice confirming the reactivation. This is different from a first-time application where the IRS assigns a brand-new number.

How much does ITIN reactivation cost in 2026?

The IRS charges $0. Form W-7 is free on irs.gov. Professional service fees cover preparation and submission. itin.so charges $197 (Standard, 7-10 day prep) or $297 (Express, 2-3 day prep). Both include W-7 preparation, CAA document certification, IRS submission, and 100% money-back guarantee.

What documents do I need to reactivate my ITIN?

A valid passport proves both identity and foreign status in 1 document. Without a passport, you need 2 from the IRS-approved list of 13 documents: national ID, birth certificate, driver's license, voter registration card, military ID, US visa, or others. All must be originals or agency-certified copies. Notarized copies are not accepted.

Can I reactivate my ITIN online?

The IRS does not accept online ITIN reactivation. You must submit a paper Form W-7 by mail, in person at an IRS Taxpayer Assistance Center, or through a Certifying Acceptance Agent. Services like itin.so handle preparation digitally but submit the final package on paper as required by IRS rules.

What is Rev Proc 2015-35 and how does it affect reactivation?

Rev Proc 2015-35 is the IRS revenue procedure governing ITIN renewal rules. It established the 3-year non-use expiration rule, the rolling middle-digit schedule, and the provision that standalone renewals do not require a federal tax return. All ITIN reactivations follow this procedure.

Can I reactivate family members' ITINs in the same mailing?

Yes. Include separate Form W-7 applications and identity documents for each family member in 1 package. Renewing everyone together prevents the IRS from stripping credits tied to family members with expired ITINs. Each person needs their own W-7 and identity documents.

How do I prevent my ITIN from deactivating again?

File a federal tax return at least once every 3 years using your ITIN. Even a zero-income return resets the non-use clock. Track the middle-digit schedule on irs.gov and renew proactively before your digits are retired. Keep your IRS address current using Form 8822 so you receive CP48 expiration notices.
