What is an ITIN?

ITIN stands for Individual Taxpayer Identification Number.

It is a nine-digit tax processing number issued by the Internal Revenue Service (IRS) for individuals who need a U.S. taxpayer identification number for federal tax purposes but are not eligible for a Social Security Number (SSN).

In simple terms: if you have a federal tax obligation in the United States and cannot obtain a Social Security Number, you may need to apply for an ITIN. However, not having a Social Security Number does not automatically mean you need an ITIN; a valid federal tax purpose under IRS rules must exist.

The general application process follows 5 steps:

  1. 1. Determine Federal Tax Purpose: Identify your valid federal tax reason before preparing paperwork.
  2. 2. Prepare Form W-7: Fill out Form W-7 — Application for IRS Individual Taxpayer Identification Number for each applicant.

  4. 4. Gather Identification Documents: Provide valid proof of identity and foreign status.
  5. 5. Submit Application via Approved Method: Submit by mail, at an IRS Taxpayer Assistance Center (TAC), or through an authorized Certifying Acceptance Agent (CAA).

What Documents Do I Need for an ITIN?

Can I Apply for an ITIN with Only a Passport?

In many cases, yes. A valid, unexpired passport is the only stand-alone document accepted by the IRS to verify both identity and foreign status without needing supplementary documents.

What if I Don't Have a Passport?

You can still apply. The IRS allows combinations of at least two alternative approved documents (e.g., a certified translated birth certificate plus a consular ID or driver's license), with at least one containing a photograph.

Can I Get an ITIN Without a Social Security Number?

Yes. The ITIN program exists specifically for individuals who need a federal taxpayer ID but are not eligible for an SSN.

Can I File Taxes with an ITIN?

What is Form W-7?

What if My ITIN is Expired? Renewal Rules

An ITIN not used on a federal tax return for three consecutive tax years expires on December 31 following the third consecutive year of non-use. Renewals require submitting a new Form W-7 with updated identification documents.

How Long Does It Take to Get an ITIN in 2026 / 2027?

The IRS typically takes approximately 7 weeks during standard periods, and 9 to 11 weeks during peak tax season (January 15 to April 30) or for applications submitted from abroad.
