Who this is for

An ITIN begins with a U.S. tax purpose

An Individual Taxpayer Identification Number may be needed by someone who has a U.S. federal tax purpose but is not eligible for a Social Security number. We review your circumstances before recommending an application.

  • Individuals who need a U.S. taxpayer identification number for a federal tax filing
  • Applicants whose U.S. tax situation connects to income, family, business, or assets across borders
  • People applying for the first time or resolving a prior Form W-7 question

Common questions

What to know before applying

The IRS reviews the application and decides whether to issue an ITIN.

Do I need to include a U.S. tax return?

Generally, Form W-7 is submitted with a federal tax return unless an IRS exception applies. We review which rule fits your case.

Can a CAA review every document?

CAA authority has limits that depend on the document and applicant. We confirm which originals or certified copies the IRS requires for your application.

Does an ITIN allow me to work in the U.S.?

No. An ITIN is for federal tax purposes and does not provide work authorization or change immigration status.
