How is itin.so authorized by the IRS?

We work with IRS-authorized Certifying Acceptance Agents to prepare and submit your ITIN application. This authorization is governed by IRS Publication 1915 and requires passing an IRS suitability check, completing approved training, and maintaining annual certification. The result: you do not need to mail your original passport to the IRS. Our CAA partners verify and certify your identity documents using IRS Form 13551 (Certificate of Accuracy) on your behalf. Your passport stays with you throughout the entire process.

Our authorization can be verified through the IRS Acceptance Agent directory.

Why was itin.so built?

Getting an ITIN should not cost $300-$500 or take weeks of back-and-forth. We saw non-US residents struggling with confusing IRS forms, expensive services, and long wait times. So we built a service that starts at $197 and prepares applications in as few as 2-3 business days. Our mission: make the ITIN process fast, affordable, and accurate for every applicant in every country.

What commitments does itin.so make to applicants?

Accuracy on every application

Every application is reviewed by our team before submission to the IRS. Form W-7 errors are the #1 cause of ITIN rejections. We catch them before the IRS does. Our review covers all 13 accepted document types.

Express ($297) completes preparation in 2-3 business days with WhatsApp support and a full money-back guarantee if the IRS declines due to a preparation error. Both include Form W-7 preparation, document review, CAA certification, and IRS submission.

How do I verify itin.so IRS authorization?

You can verify our partner's Certifying Acceptance Agent status directly through the IRS website. Visit the IRS Acceptance Agent directory at irs.gov/individuals/international-taxpayers/acceptance-agents-united-states. All authorized CAAs are listed with their name, location, and contact details. We provide our agent credentials upon request.

Does itin.so offer a money-back guarantee?

Yes. The Express service ($297) includes a full money-back guarantee if the IRS declines your ITIN application due to a preparation error on our part. This covers Form W-7 errors, document certification issues, and submission mistakes. The guarantee does not cover rejections due to applicant eligibility issues or false information provided by the applicant.

How does itin.so handle document verification remotely?

We use secure video verification to review your original identity documents. During the video session, our CAA partner examines your passport or other documents, confirms authenticity, and issues IRS Form 13551 (Certificate of Accuracy). This process is approved by the IRS and eliminates the need to mail original documents. Your passport never leaves your hands.

What happens after itin.so submits my application to the IRS?

After submission, the IRS processes your application in 6-11 weeks. Express customers receive WhatsApp updates on their application status. You can also call the IRS at 1-800-829-1040 after 7 weeks to check status. Once approved, the IRS mails your ITIN assignment notice (CP565) to the address on your Form W-7.

Can itin.so help with ITIN renewals?

Yes. We offer ITIN renewal service for $97. Renewals follow a similar process to new applications: we prepare Form W-7 with the renewal checkbox marked, review your updated identity documents, and submit to the IRS. ITINs expire if unused on a federal tax return for 3 consecutive years per IRS Notice 2016-48.

Does itin.so also help with EIN applications?

Yes. Many clients who need an ITIN also need an EIN (Employer Identification Number) for their US LLC or business. We offer EIN application services that can be bundled with your ITIN application. An EIN identifies your business entity, while your ITIN identifies you personally for tax purposes under IRC Section 6109.
