ITIN for Non-Residents

It exists so you can file. It changes nothing else
The lead

An Individual Taxpayer Identification Number looks like a Social Security Number — nine digits in the same XXX-XX-XXXX shape — and is instantly distinguishable because it always begins with a 9. That resemblance is where the trouble starts, because people reasonably assume the two numbers do similar things. They do not.

Business · ITIN for Non-Residents

An ITIN does not authorize you to work as an employee in the United States. It does not provide eligibility for Social Security benefits. It does not alter your immigration status. What it does is let a person who is not eligible for an SSN comply with United States tax obligations — which becomes mandatory the moment a U.S. corporation or LLC you own generates income.

And the application itself carries a real cost that has nothing to do with money: done alone, it often means posting your original, physical passport to a federal processing centre and waiting months for it to come back.

Start here

Three ways in, by what brought you here.

The format, the eligibility, and the four things it does not grant.

A U.S. entity generating income is what makes the filing mandatory.

The other numbers

Two of them identify a person and one identifies a company. The company’s number lives in the neighbouring section of this edition.

Errors of form

Three ways an application comes back, or never comes back at all
One field

The IRS applies strict documentation rules to this form. A single formatting error results in an outright rejection, and the delay lands on the business that was waiting for the number.

The passport in the post

Applying alone often means mailing your original, physical passport to a federal processing centre for months. There are ways to avoid that, and they are decided before the envelope is sealed.

The wrong expectation

It does not authorize employment, it does not create eligibility for Social Security benefits, and it does not alter immigration status. Planning around any of those is planning around nothing.

What it is not

Three assumptions the resemblance to an SSN produces

An ITIN does not authorize you to work as an employee in the United States. Work authorization is a separate matter entirely, and no taxpayer number confers it.

Employment stays where it was

It does not provide eligibility for Social Security benefits. The nine-digit resemblance is a formatting coincidence, not a shared function.

No benefits attached

It does not alter your immigration status in any direction. Applying for one neither improves nor endangers a position; it is a tax-compliance instrument.

Status unchanged

The number

What it is, and who it is for

Format, eligibility, the comparison with an SSN, and the four things it does not grant.

An EIN identifies the entity, not the person. Different section, different problem.

The process

Form W-7, and what it demands

Submitting Form W-7, the documentation rules, and the passport question.

Once a U.S. corporation or LLC you own generates income, a personal tax return follows.

The file

Four things this section settles
9
How it starts

An ITIN is formatted like an SSN but always begins with the number nine, which makes it immediately identifiable.

W-7
The form

The application is Form W-7, submitted to the IRS under strict documentation rules.

0
Rights it grants

Not employment authorization, not Social Security eligibility, not any change of immigration status.

1
Thing it is for

Complying with United States tax obligations when you are not eligible for an SSN.

Notary Public Center

The identity documents, certified without leaving your passport in the post

The hardest part of a W-7 is proving identity with original documents. Notary Public Center prepares and certifies the document set a U.S. filing requires, and handles the authentication when any of it has to cross a border.
