We're on a mission to make U.S. tax identification accessible to everyone, everywhere in the world.
What does IRS-Authorized mean?
ITIN.io is operated by Clemta, an IRS-authorized Certifying Acceptance Agent (CAA). This is a special designation granted by the Internal Revenue Service that allows us to verify identity documents and certify them on behalf of applicants. This means you never need to mail your original passport to the IRS — we verify it via a secure video call and submit certified copies directly.
Only authorized CAAs can provide this level of service. This authorization ensures your application is handled with the highest standards of compliance and security.

Making ITIN accessible globally
Clemta was founded with a simple belief: starting and managing a U.S. business should be accessible to entrepreneurs worldwide. As we helped thousands of international business owners form companies in the U.S., we saw firsthand how challenging the ITIN process was.
Applicants were forced to mail their passports internationally, wait months for processing, and navigate complex IRS forms without guidance. Many applications were rejected due to simple errors.
We built ITIN.io to solve this problem. By becoming an IRS-authorized Certifying Acceptance Agent, we can verify documents via video call, prepare error-free applications, and submit directly through authorized channels — cutting processing time in half and eliminating the need to mail passports.
