Most applicants need to submit at least one original or certified copy of a primary identification document and one original or certified copy of a foreign status document. You will typically submit these documents along with Form W-7, Application for IRS Individual Taxpayer Identification Number, and a U.S. federal income tax return. The question of how many documents are required for an ITIN hinges on proving two key elements: your identity and your foreign (non-U.S.) status. The IRS has specific requirements for these documents to ensure accuracy and prevent fraud.
Understanding the Core Documentation Requirements
The IRS requires you to provide proof of your identity and foreign status when applying for an ITIN. This is usually done by submitting original documents or certified copies from the issuing agency. While the exact number might vary slightly based on the specific documents chosen, the fundamental requirement is to present at least one document for identity and one for foreign status. These documents must be current and not expired. You cannot use a single document to satisfy both requirements simultaneously. For instance, a passport serves as both a primary identification document and a foreign status document, so it can satisfy both requirements on its own. However, if you choose to use a driver's license for identity, you must also provide a separate document proving foreign status.
Primary Identification Documents
You must provide at least one original or certified copy of a primary identification document to prove your identity. These documents must contain your name, photograph, current address (in most cases), and date of birth. Examples of acceptable primary identification documents include:
- U.S. Passport: This is the most commonly used document as it also proves foreign status.
- National Identity Card: Must show name, photograph, date of birth, and issue/expiration dates.
- Foreign Driver's License: Must show name, photograph, date of birth, and issue/expiration dates.
- 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 issue/expiration dates.
- Civil Birth Certificate: For U.S. citizens or resident aliens only. Must show name, date and place of birth, and parents' names.
- U.S. State Driver's License: Must show name, photograph, date of birth, and issue/expiration dates.
- U.S. State Identification Card: Must show name, photograph, date of birth, and issue/expiration dates.
- Foreign or U.S. Military Card: Must show name, photograph, and expiration date.
If your chosen primary identification document does not contain your current address, you will need to provide a secondary identification document that does. The IRS aims to ensure that the applicant's name and photograph are clearly visible on the document submitted.
Foreign Status Documents
In addition to a primary identification document, you must provide at least one original or certified copy of a document that proves your foreign status. These documents must show your name and indicate that you are a non-U.S. national or eligible foreign national. Examples of acceptable foreign status documents include:
- Passport: As mentioned, a passport can serve as both a primary identification document and a foreign status document.
- Birth Certificate: Must show your name, date of birth, place of birth, and parents' names. This is acceptable only if it establishes your place of birth in a foreign country.
- National Identification Card: Must show name, photograph, date of birth, and issue/expiration dates.
- Foreign Driver's License: Must show name, photograph, date of birth, and issue/expiration dates.
- Foreign Voter's Registration Card: Must show name, photograph, date of birth, and issue/expiration dates.
- Immigration Card: Such as a Permanent Resident Card (Green Card) or Employment Authorization Document (EAD).
- Visa: Must show your name, expiration date, and nationality.
If you are applying as a dependent or spouse, the documentation requirements will also include proof of your relationship to the applicant, such as a birth certificate or marriage certificate. The IRS provides a comprehensive list of acceptable documents in the instructions for Form W-7.
The Role of Form W-7 and Tax Returns
Beyond identification and foreign status documents, Form W-7 itself is a critical document in the application process. This form collects essential personal information, including your name, address, and the reason for applying for an ITIN. You must also submit a valid U.S. federal income tax return with your Form W-7 application, unless you qualify for an exception. The tax return demonstrates your need for an ITIN, which is primarily for tax purposes. For example, if you are a non-resident alien earning U.S. source income, you will likely need to file Form 1040-NR, U.S. Nonresident Alien Income Tax Return, to report that income and claim any applicable deductions or credits. The IRS will not process your Form W-7 without an accompanying tax return (or a valid exception). This is a fundamental part of answering how many documents are required for an ITIN; the tax return is a key document.
Exceptions to the Tax Return Requirement
While submitting a tax return is the standard requirement, there are several exceptions where you can apply for an ITIN without attaching a tax return. These exceptions are detailed in the Form W-7 instructions and typically involve situations where an ITIN is needed for other tax-related purposes. Common exceptions include:
- Third-party withholding and backup withholding: If you have U.S. income subject to withholding, and the payer requires an ITIN.
- Tax treaty benefits: If you are claiming tax treaty benefits on U.S. income.
- Dependents and spouses of U.S. citizens/resident aliens: When applying for an ITIN for a dependent or spouse who is not eligible for a Social Security Number.
- Nonresident alien claiming treaty benefits: For individuals who are not required to file a tax return but wish to claim treaty benefits.
- Students, professors, or researchers: Individuals attending or teaching at an educational institution or involved in research, who may need an ITIN for certain tax reporting or benefits, even if not filing a full return.
If you fall under one of these exceptions, you will need to provide documentation to support your claim, such as a letter from the withholding agent or proof of treaty benefits. The specific documentation will depend on the exception you are claiming.
Applying Through a Certified Acceptance Agent (CAA)
One of the most convenient ways to apply for an ITIN is through a Certified Acceptance Agent (CAA). These individuals or entities are authorized by the IRS to assist applicants in obtaining ITINs. When you apply through a CAA, you do not need to send your original identification documents to the IRS. Instead, the CAA will verify your original documents or certified copies and forward certified copies of your documentation along with your Form W-7 and tax return to the IRS. This process is often faster and more secure, as you get your original documents back immediately. The itin.net service acts as a CAA, simplifying the process for many applicants. The number of documents you present to the CAA is the same as if you were applying directly to the IRS, but the verification process is handled by the CAA, reducing your risk of losing important original documents.
Other Potential Documents and Situations
In certain complex situations, you might need to provide additional documentation. For example, if you are applying for an ITIN for a business purpose, such as establishing a U.S. presence or opening a U.S. bank account for a U.S. LLC, you may need to provide supporting documents related to that business. This could include articles of incorporation, an operating agreement, or documentation related to the formation of your U.S. LLC. If you are looking to open a U.S. bank account, an ITIN is often a necessary step, and the bank may have its own specific requirements for verifying your identity and residency, though these are separate from the IRS ITIN application. For individuals forming a U.S. LLC, obtaining an EIN (Employer Identification Number) via Form SS-4 is also a common step, and this process has its own documentation requirements, separate from the ITIN application. Even if not directly required for the ITIN itself, these business-related documents might be necessary for the underlying reason you need the ITIN.
Common Mistakes and How to Avoid Them
When gathering documents for your ITIN application, several common mistakes can lead to delays or rejections. One frequent error is submitting photocopies instead of original documents or certified copies. The IRS will not accept standard photocopies unless they are certified by the issuing agency or a CAA. Another mistake is using expired identification documents. Always ensure that your passport, driver's license, or national identity card is valid and has not passed its expiration date. Incomplete applications are also a major cause of delays; ensure all sections of Form W-7 are filled out accurately and completely, and that your accompanying tax return is also complete. Finally, failing to provide sufficient documentation to prove both identity and foreign status is a common pitfall. Double-check the IRS Form W-7 instructions to confirm you have at least one valid document for each category, unless a single document like a passport covers both. Understanding how many documents are required for an ITIN starts with a careful review of these requirements.
Processing Times and What Happens Next
Once your Form W-7 application and supporting documents are submitted to the IRS, processing times can vary significantly. Currently, the IRS estimates processing times for ITIN applications can range from 7 to 11 weeks, though this can fluctuate based on the volume of applications received. If your application is approved, you will receive an ITIN via mail. If it is rejected, you will receive a notice explaining the reasons, and you can reapply. After obtaining your ITIN, you may need to file annual U.S. tax returns, especially if you continue to have U.S. source income or are subject to reporting requirements like Form 5472 for U.S. business owners. ITINs also expire after a certain period of inactivity and may need to be renewed. The IRS typically sends a notice if your ITIN needs renewal. For those who started their tax journey with an ITIN, the next steps often involve understanding U.S. business structures like LLCs or obtaining an EIN for business operations. Consult with a tax professional or a service like itin.net for guidance on these subsequent steps.
