Apply for ITIN Online: IRS-Authorized Service (2026)

What Does "Apply for ITIN Online" Actually Mean in 2026?

The IRS does not operate a self-service online portal for Form W-7. "Apply for ITIN online" refers to the CAA-handled workflow: the applicant completes intake on a web form, uploads identity documents, joins a live video call with an IRS-Certified Acceptance Agent, and the CAA prepares and ships the verified packet to the IRS ITIN Operation in Austin, Texas.

The online portion replaces three slow steps in the legacy paper process: mailing original passports, visiting an IRS Taxpayer Assistance Center, and printing/posting Form W-7 packets. The packet that reaches the IRS is still paper, but every applicant action happens online. For the broader application path, see the How to Get an ITIN Number guide.

How Does the Online ITIN Application Work Step by Step?

1. Start intake. Fill the secure online form with legal name, date of birth, country of citizenship, US address (if any), foreign address, and Form W-7 line 6 reason code.
2. Upload documents. Color scan of the passport photo page, signature page, and any supporting documents the selected reason code requires. Tax return PDF if filing one with the W-7.
3. Pay $297. One flat fee, no tiers. Credit card, Apple Pay, Google Pay, or PayPal.
4. Verify on video. 10-minute Zoom call with a CAA. The agent inspects the live passport and matches it to the uploaded scan, satisfying IRS document verification rules.
5. Sign and submit. The CAA prepares Form W-7, attaches the certified document copies and any required tax return, and mails the packet to the IRS Austin Service Center via tracked courier.
6. Receive ITIN. The IRS mails the CP565 notice with the assigned ITIN to the foreign address on file. The CAA also receives a CAA-specific notification and forwards the ITIN number digitally within 7 business days of IRS assignment.

Why Choose a Certifying Acceptance Agent for the Online ITIN Application?

A Certifying Acceptance Agent is authorized by the IRS to verify identity documents on behalf of ITIN applicants. The CAA route is the only online path that:

• Avoids mailing original passports across borders.
• Removes the need to visit an IRS Taxpayer Assistance Center in the United States.
• Pre-checks Form W-7 for the most common rejection causes (wrong reason code, missing signature, document mismatch).
• Maintains a direct correspondence channel with the IRS ITIN Operation if the application needs follow-up.

For background on the CAA program, see the Certifying Acceptance Agent page.

See the ITIN cost guide for a full pricing breakdown.

How Long Does the Online ITIN Application Take End to End?

The total time has two distinct phases. The CAA-controlled phase (intake, video call, document prep, courier dispatch) finishes in 48 to 72 hours. The IRS-controlled phase (W-7 review, ITIN assignment, CP565 mailing) takes 7 to 11 weeks during off-peak months and 9 to 13 weeks from January through April.

For a week-by-week breakdown, see the ITIN processing time guide and the application status page.

What If the Online ITIN Application Is Rejected?

The IRS sends a CP566 notice listing the rejection cause. CAA-prepared packets have lower rejection rates because the agent pre-checks Form W-7 and certifies documents on-site, but rejection still happens (typically for missing tax returns or out-of-date passports). itin-number.com resubmits corrected packets at no extra fee for any issue caused by preparation error.
