ITIN application help, without the guesswork

If you need to file or be claimed on a U.S. tax return but don't qualify for a Social Security Number, you need an ITIN. We guide your Form W-7 application so it's done right the first time — rejected applications cost months.

An ITIN — Individual Taxpayer Identification Number — lets people who can't get a Social Security Number still meet their U.S. tax obligations. You might need one to file a return, to be claimed as a spouse or dependent, to open certain accounts, or to comply as the owner of a U.S. business.

The application itself (Form W-7) looks simple, but it's where people get stuck. The reason for applying must be correct, the supporting documents have to meet strict rules, and originals or certified copies are usually required. A small mistake means a rejection — and weeks or months of delay, often right when a tax deadline is looming.

We help you apply correctly: the right reason, the right documents, filed properly alongside the return when one is required. And because we're a licensed Enrolled Agent, your tax filing and your ITIN are handled together by one professional.

Common questions

What's the difference between an ITIN and an SSN?

An SSN is for people authorized to work in the U.S. An ITIN is purely for tax purposes, for people who need to file or be listed on a U.S. return but can't get an SSN. It doesn't grant work authorization or immigration status.

How long does it take to get an ITIN?

Processing typically takes several weeks, and longer during peak tax season. Applying correctly the first time is the best way to avoid adding months through a rejection.

Do I have to mail my original passport?

Documentation rules are strict and depend on your situation. We walk you through which documents are accepted and the safest way to provide them, so you're not sending originals unnecessarily.

Can I apply for an ITIN without filing a tax return?

In most cases an ITIN application must be attached to a tax return, but there are specific exceptions. We confirm which applies to you before you apply.

My ITIN is old — is it still valid?

ITINs can expire if not used or after a set period. If yours has lapsed, we help you renew it so your next filing isn't delayed.
