Documents Required for an ITIN Application

Submitting the correct documents is one of the most important steps when applying for an Individual Taxpayer Identification Number (ITIN). A complete and accurate application can help avoid delays and ensure your request is properly reviewed by the IRS.

Why Documents Matter

The IRS requires documentation to verify the applicant’s identity, foreign status, and eligibility for an ITIN. Incomplete or incorrect documentation is one of the most common reasons applications experience delays.

Required Categories of Documents

1. Identity

The document must establish who you are, such as your full legal name, date of birth, and photograph when applicable.

2. Foreign Status

The document must establish that you are a foreign individual. Some documents can prove both identity and foreign status.

Commonly Accepted Documents

Examples may include:

  • Passport.
  • National identification card.
  • Foreign driver’s license.
  • Birth certificate.
  • Medical records for dependents in certain situations.
  • School records for dependents in certain situations.

Not every document is accepted in every case.

Original Documents vs. Certified Copies

Depending on how the application is submitted, the IRS may require original documents, certified copies from the issuing agency, or documentation reviewed through an authorized process. Unacceptable copies can result in delays or rejection.

Applying Through a Certifying Acceptance Agent

A Certifying Acceptance Agent (CAA) is authorized by the IRS to assist eligible applicants. A CAA may review documentation, verify certain information, assist with Form W-7, and help ensure the application package is complete.

Common Mistakes

  • Sending expired or unacceptable documents.
  • Providing inconsistent information.
  • Forgetting required forms.
  • Submitting an incomplete application.
  • Assuming any identification document will be accepted.
