To apply for an Individual Taxpayer Identification Number (ITIN), you must submit specific documents to the IRS proving your identity and foreign status. The primary document for your application is Form W-7, Application for IRS Individual Taxpayer Identification Number. This form itself is not the sole requirement; it must be accompanied by original or certified copies of identification documents and proof of foreign status, along with the relevant tax return if applicable.
Understanding exactly what are the documents required for itin application is the first step toward a successful submission. The IRS has strict requirements to prevent fraud and ensure accuracy. Failure to provide the correct documentation will result in delays or rejection of your application. This guide details the necessary items, how to present them, and what to expect.
Required Documentation for Form W-7
The IRS requires you to submit Form W-7 along with supporting documentation. You have two main options for submitting your application: by mail directly to the IRS or through a Certified Acceptance Agent (CAA). Both methods require the same core documentation, but the submission process differs.
Identification Documents
You must provide original or certified copies of documents that prove both your identity and your foreign status. You need to submit one document from the list that shows both identity and foreign status, OR one document proving identity and one document proving foreign status. The identification document must contain your name, photograph, current address, and date of birth.
Acceptable identification documents include:
- U.S. Passport: This is often the preferred document as it proves both identity and foreign status.
- National Identity Card: Must show name, photograph, date of birth, and expiration date.
- Foreign Driver's License: Must show name, photograph, date of birth, and expiration date.
- Foreign Military Identification Card: Must show name, photograph, date of birth, and expiration date.
- Foreign Voter's Registration Card: Must show name, photograph, date of birth, and expiration date.
- Civil Birth Certificate: Must show name, date of birth, and place of birth. If the birth certificate is not in English, a certified translation must accompany it.
- National Health Insurance Card: Must show name, photograph, date of birth, and expiration date.
- Bank Statement: Must show name, photograph, date of birth, and expiration date.
- Foreign Driver's License: Must show name, photograph, date of birth, and expiration date.
- Foreign Military Identification Card: Must show name, photograph, date of birth, and expiration date.
- Foreign Voter's Registration Card: Must show name, photograph, date of birth, and expiration date.
- Civil Birth Certificate: Must show name, date of birth, and place of birth. If the birth certificate is not in English, a certified translation must accompany it.
- National Health Insurance Card: Must show name, photograph, date of birth, and expiration date.
- Bank Statement: Must show name, photograph, date of birth, and expiration date.
- Medical Records: Must show name, photograph, date of birth, and expiration date.
- School Records: Must show name, photograph, date of birth, and expiration date.
Proof of Foreign Status
If your primary identification document does not also prove your foreign status (e.g., a passport does), you must provide a separate document that establishes you are a non-U.S. resident. Documents that prove foreign status include:
- Visa: A valid U.S. visa is strong proof of foreign status.
- I-94 Arrival/Departure Record: This record, issued by U.S. Customs and Border Protection, confirms your lawful entry into the U.S.
- Other Immigration Documents: Such as a Permanent Resident Card (though this would typically lead to an SSN, not an ITIN), or other documents issued by U.S. Citizenship and Immigration Services (USCIS).
Tax Return (If Applicable)
For most applicants, an ITIN is required to file a U.S. federal income tax return. Therefore, you must attach your completed Form W-7 to your U.S. federal income tax return (e.g., Form 1040-NR for non-resident aliens). The tax return must be accurate and complete. If you are applying for an ITIN solely to claim tax treaty benefits or for other specific reasons not related to filing a tax return, you may not need to attach a tax return, but you must clearly state the reason on Form W-7.
There are specific exceptions where an ITIN is needed without filing a tax return, such as for certain withholding requirements or for U.S. business formation purposes. For instance, if you are forming a U.S. LLC and need to obtain an EIN (Employer Identification Number) for it, you might need an ITIN if you are a foreign individual without a U.S. tax filing obligation. In such cases, you would typically attach Form SS-4, Application for Employer Identification Number, to your Form W-7.
Certified Copies vs. Originals
When submitting documents by mail, the IRS has specific rules about what they accept. You can send original documents, but the IRS warns that they are not responsible for lost or stolen original documents. Alternatively, you can submit certified copies of your identification documents. Certified copies are obtained from the issuing agency (e.g., the passport office or department that issued your national ID).
If you choose to use a Certified Acceptance Agent (CAA), they can verify your original documents and send certified copies to the IRS on your behalf. This means you do not have to mail your original identification documents, which offers a significant security advantage. itin.net works with CAAs to help clients with their ITIN applications.
Submitting Your Application
Option 1: Mail Your Application Directly to the IRS
If you choose to mail your application, you will send Form W-7, your completed U.S. federal income tax return (if required), and your original or certified identification documents to the IRS address listed in the Form W-7 instructions. The IRS will process your tax return and your Form W-7 simultaneously. They will mail your original identification documents back to you after processing, which can take several weeks.
Option 2: Apply Through a Certified Acceptance Agent (CAA)
Applying through a CAA is often the preferred method for many applicants. CAAs are individuals or entities authorized by the IRS to help taxpayers apply for ITINs. They are trained to review your documentation, verify your identity, and submit your application directly to the IRS. The key benefit is that CAAs can certify your original identification documents, meaning you get them back immediately after your appointment. This avoids the risk and delay associated with mailing original documents.
CAAs can assist with the entire Form W-7 process. After verifying your documents, they will forward your application package to the IRS ITIN Operation. This service can streamline the process and reduce the chances of errors.
Common Reasons for Application Rejection
Even when meticulously gathering what are the documents required for itin application, applicants can face rejection due to common mistakes. Awareness of these pitfalls can help ensure a smoother process.
- Missing Documentation: Failing to include all required identification and proof of foreign status documents is a primary reason for rejection. Ensure you have one document proving both, or one of each.
- Unacceptable Documents: Submitting documents that do not meet IRS criteria (e.g., expired IDs, documents without photographs when required, or photocopies instead of certified copies).
- Incomplete Form W-7: Errors or omissions on the Form W-7 itself, such as incorrect Social Security Number (if applicable, though unlikely for an ITIN applicant), missing signatures, or incorrect personal information.
- Incorrect Tax Return: If attaching a tax return, it must be complete, signed, and accurate. Errors on the tax return will cause the Form W-7 to be rejected.
- Failure to Meet Exceptions: If applying without a tax return, the stated reason must clearly fall within IRS exceptions, and supporting documentation for that exception must be provided.
What Happens After Application Approval?
Once the IRS approves your Form W-7 application, you will receive an official ITIN assignment letter, typically IRS Letter CP-565. This letter will contain your unique 9-digit ITIN. It is crucial to keep this letter and your ITIN confidential and secure. You will need this ITIN for all future U.S. tax filings.
If your ITIN application was tied to a tax return, the IRS will process that return. If you applied for an ITIN to obtain an EIN for a U.S. LLC, you would have submitted Form SS-4 with your Form W-7. Once approved, you would receive your EIN confirmation letter and your ITIN letter separately.
ITIN Renewal and Expiration
ITINs do not expire automatically, but they can become invalid if not used for three consecutive tax years. Additionally, the IRS has recently implemented a renewal program for certain ITINs. If your ITIN has not been used on a federal tax return for three consecutive years (2021, 2022, 2023, for example), it may be deactivated. Furthermore, ITINs issued before January 1, 2013, may need to be renewed periodically based on IRS announcements.
If your ITIN has been deactivated or you believe it needs renewal, you will need to submit a new Form W-7 along with updated identification documents and a federal tax return for the relevant tax year. The process is similar to the initial application.
Seeking Assistance with Your Application
Navigating the requirements for what are the documents required for itin application can be complex. The IRS provides resources, including its website and CAAs, to help. For many, especially those living abroad or unable to travel to an IRS Taxpayer Assistance Center (TAC), using a Certified Acceptance Agent (CAA) is the most practical and secure method.
CAAs can save you time and reduce the stress of the application process. They are trained to ensure your application is complete and accurate. If you are planning to form a U.S. LLC, open a U.S. bank account, or obtain an EIN, having an ITIN is often a foundational step. itin.net can guide you through these processes and connect you with the right resources.
For more complex situations, such as those involving tax treaty benefits, specific business structures, or U.S. banking needs with services like Mercury, Relay, or Brex, consulting a qualified tax professional or attorney is advisable.
