ITIN documentation encompasses the specific identification documents you must submit to the Internal Revenue Service (IRS) to prove your identity and foreign status when applying for an Individual Taxpayer Identification Number (ITIN). Without this proper documentation, your application for an ITIN will be rejected. The core purpose of these documents is to satisfy the IRS that you are who you say you are and that you are not a U.S. citizen or a resident alien eligible for a Social Security Number (SSN).
Understanding what is ITIN documentation is the first step in a successful application process. The IRS has strict requirements for these documents to prevent identity fraud and ensure the integrity of the ITIN system. These requirements are designed to be rigorous yet achievable for most applicants.
Types of Acceptable Identification Documents
The IRS accepts original identification documents or certified copies from the issuing agency. You cannot submit photocopies unless they are certified. The most commonly accepted documents are:
Primary Identification Documents
These documents must contain a recent photograph, your name, address, date of birth, and expiration date. They must be valid (not expired) at the time of application. The IRS requires you to present one of the following:
- U.S. Federal or State-issued Identity Card: This could include a state-issued driver's license or a state-issued identification card. Ensure it meets all the photographic and data requirements.
- Foreign Government-Issued Identification: This is often the most practical option for non-residents. Examples include:
- Foreign Driver's License: A valid driver's license issued by your country of residence. It must contain all required information.
- National Identity Card: Many countries issue national identity cards that serve as primary identification. These must include a photo, name, address, date of birth, and expiration date.
- Foreign Military Identification Card: If applicable, this can be used, provided it contains the necessary identifying information and a photograph.
- Visa: A valid U.S. visa, if you are in the U.S. for a purpose requiring an ITIN (e.g., filing a tax return). The visa must be current.
Supporting Identification Documents
In addition to a primary identification document, you must also provide a document that supports your foreign status and, in some cases, your name and date of birth. You must present one of the following:
- Birth Certificate: This is a common supporting document. It must clearly show your name and date of birth. If the birth certificate is not in English, you must provide a certified translation.
- National Identification Card: Even if not used as a primary ID (e.g., if it lacks a photo or is expired), it can serve as supporting documentation if it contains your name and date of birth.
- Foreign Driver's License: If not used as a primary ID, it can support your foreign status and identity.
- Civil Birth Certificate: Similar to a birth certificate, but may be issued by local civil authorities.
- Foreign Voters Registration Card: If issued by your home country and contains your name and date of birth.
- Original or Certified Copy of a Consular Identification Card: Issued by your country's consulate in the U.S.
- U.S. Military Identification Card: Applicable if you are a dependent of active U.S. military personnel.
- Medical Records (U.S. only): For individuals under 18, medical records from a U.S. hospital or clinic can sometimes be used, provided they show name and date of birth.
- School Records (U.S. only): Similarly, for individuals under 18, school records from a U.S. school showing name and date of birth may be accepted.
Important Note: The IRS is very specific about which documents are acceptable. Always check the latest IRS guidance on Form W-7 instructions for the most up-to-date list and requirements. If you are unsure about a document's acceptability, it is best to consult with a professional or use a Certified Acceptance Agent (CAA).
What is ITIN Documentation for Minors?
For applicants under 18 years old, the documentation requirements are slightly different. The primary identification document must prove the applicant's identity and foreign status. The supporting document must prove the applicant's age and foreign status.
If a parent or legal guardian is applying on behalf of a minor, they will need to provide their own identification documents as well.
What is ITIN Documentation for Entities?
ITINs are for individuals, not entities. Businesses that need a tax identification number should apply for an Employer Identification Number (EIN), also known as an Employer Identification Number, using Form SS-4. This is a separate process from obtaining an ITIN. You can learn more about applying for an EIN on our /ein page.
Authenticity and Certification of Documents
When submitting ITIN documentation, you have a few options:
- Apply in Person at the IRS: You can take your original documents or certified copies to an IRS Taxpayer Assistance Center (TAC). An IRS employee will verify your documents and return them to you on the same day. This requires an appointment.
- Apply by Mail: You can mail your original documents or certified copies directly to the IRS ITIN Operation. The IRS will return your original documents within 60 days of receipt. Be prepared for this mail-in process to take time.
- Apply Through a Certified Acceptance Agent (CAA): This is often the most convenient method. A CAA is an individual or entity authorized by the IRS to assist applicants in obtaining an ITIN. CAAs can authenticate your original identification documents or certified copies, meaning you do not have to mail your originals to the IRS. The CAA will forward your application and documentation to the IRS. itin.net is a service that can help you through this process, offering assistance with your ITIN application via a CAA. Using a CAA streamlines the process and reduces the risk of losing your original documents.
Certified Copies: If you cannot present original documents, you can obtain certified copies from the agency that issued the document (e.g., the passport office for a passport, the vital records office for a birth certificate). Some countries' consulates in the U.S. can also certify documents. Photocopies made by a notary public are generally not accepted by the IRS.
Specific Documentation for Certain Situations
U.S. Tax Return Requirement
Most applicants need to submit ITIN documentation to support a valid tax reason for needing an ITIN. The most common reason is to file a U.S. federal income tax return (e.g., Form 1040-NR for non-resident aliens). Your tax return must be complete and accurate. It is attached to your Form W-7 application.
Treaty Benefits
If you are claiming benefits under a U.S. tax treaty, you will need to provide additional documentation. This typically includes:
- A completed Form W-7 with the appropriate box checked for claiming treaty benefits.
- A U.S. income tax return (e.g., Form 1040-NR) showing the income for which you are claiming treaty benefits.
- A completed Form W-8BEN (Certificate of Foreign Status of Beneficial Owner for United States Tax Withholding and Reporting (Individuals)).
- Documentation proving your residency in the treaty country.
Other Tax Reasons
Other reasons for needing an ITIN might include:
- Being a dependent of a U.S. citizen or resident alien.
- Being a dependent or spouse of a non-resident alien visa holder.
- Being a non-resident alien spouse required to file a U.S. tax return.
- Being the responsible party for reporting requirements for a U.S. LLC (Limited Liability Company) where you are a foreign owner. In this case, you may also need to file Form 5472 and potentially an EIN if the LLC requires one. Understanding these requirements early is key to setting up your U.S. business structure correctly.
- Establishing credit or opening a U.S. bank account (though this is not always a guaranteed reason for an ITIN, as some banks may have alternative procedures).
What is ITIN Documentation for Banking and Business?
While the primary purpose of an ITIN is for U.S. tax compliance, it can sometimes be a prerequisite for other financial activities for non-residents. For example, some financial institutions may require an ITIN to open a U.S. bank account, especially if you do not have a Social Security Number. However, policies vary significantly between banks like Mercury, Relay, or Brex, and some may offer alternative solutions. It is always best to confirm the specific requirements directly with the financial institution.
For individuals involved in setting up or managing a U.S. LLC, an ITIN might be necessary depending on their role and reporting obligations. As mentioned, Form 5472 is a critical form for foreign-owned U.S. disregarded entities. While an ITIN is not the same as an EIN (Employer Identification Number), which is essential for many business operations, having an ITIN can be part of the overall compliance puzzle for foreign nationals engaging in U.S. business activities.

Common Documentation Errors
Errors in ITIN documentation are the most frequent cause of application rejection. Common mistakes include:
- Expired Identification: Submitting documents that have passed their expiration date.
- Missing Required Information: Primary IDs lacking a photograph, address, or date of birth; supporting documents missing name or date of birth.
- Not Original or Certified: Submitting simple photocopies instead of originals or certified copies.
- Incorrect Document Types: Attempting to use documents not on the IRS-approved list.
- Incomplete Application: Not attaching the required documents to Form W-7 or failing to include a valid tax reason.
- Lack of Translation: Not providing certified translations for documents not in English.
