The Basics

What Is an ITIN Tax Number?

Understand how the Individual Taxpayer Identification Number works for non-U.S. residents.

Individual Taxpayer Identification Number

An ITIN is a nine-digit tax processing number issued by the IRS to people who need a US tax number but are not eligible for a Social Security Number (SSN) — including foreign nationals, non-resident aliens and dependents.

Who Needs to Apply for ITIN Tax Number Online

Non-U.S. residents with US tax filing obligations — foreign freelancers, online sellers, investors, LLC owners and expats — can apply for an ITIN from anywhere in the world, without visiting the US.

Why Apply with a Certified Acceptance Agent

A CAA prepares your Form W-7 to IRS standards, authenticates your documents and submits your ITIN application for you — greatly improving your chances of a smooth, first-time approval.
