An Individual Taxpayer Identification Number, or ITIN, is a federal tax-processing number for certain people who need a U.S. taxpayer identification number but are not eligible for a Social Security number. An ITIN does not provide work authorization or change immigration status.
Who may need an ITIN?
ITINs may be relevant for nonresident or resident aliens, spouses, or dependents who have a federal tax purpose and cannot obtain a Social Security number. Eligibility depends on the facts and the applicable tax requirement, so the first step is confirming why the number is needed.
What an application generally involves
An application typically includes Form W-7, supporting identification, and a federal tax return unless an allowed exception applies. The name, date of birth, country information, and identification details must be consistent across the application and supporting records.
Prepare identification carefully
The IRS accepts specific documents to establish identity and foreign status. A valid passport can satisfy both requirements in many cases; otherwise, a combination of acceptable documents may be necessary. Requirements differ for dependents, and additional proof of residency may apply.
Do not email identity documents or upload them to an unapproved location. Ask how documents will be reviewed, transmitted, and returned before providing originals.
How a Certifying Acceptance Agent can help
A Certifying Acceptance Agent can review qualifying identification, help complete the application package, and submit certification documentation under IRS procedures. This may reduce the need to mail certain original documents, although some circumstances still require additional steps.
When renewal may be necessary
An ITIN may expire after it is not used on a federal return for the required period. Renew only when there is a current federal tax need. Starting early can help prevent processing delays when a return depends on an active number.
Bring these items to your appointment
- The applicant’s current identification documents
- Any prior ITIN notice or number
- The tax return or documents connected to the federal tax purpose
- Immigration records when relevant to the application
- Information for the spouse, dependents, and household relationship
Avoid common delays
Expired identification, inconsistent names, incomplete addresses, missing signatures, and an unclear federal tax purpose can slow an application. Have every document reviewed before submission and retain copies of the final package and delivery information.
