The primary IRS form a taxpayer files to get an ITIN is Form W-7, Application for IRS Individual Taxpayer Identification Number. This form is the gateway for individuals who are not eligible for an SSN but need a U.S. taxpayer identification number for tax purposes. Most individuals asking which form does a taxpayer file to get an itin will find that Form W-7 is their direct answer, though the process involves more than just filling out this single document.
Who Needs an ITIN?
An ITIN is issued by the Internal Revenue Service (IRS) to help individuals who are required to have U.S. taxpayer identification but do not have, and are not eligible to obtain, a Social Security number (SSN). This typically includes:
- Non-resident aliens who need to file a U.S. tax return (e.g., to claim treaty benefits or report U.S. source income).
- U.S. resident aliens (based on days present in the U.S.) who are not eligible for an SSN.
- Dependents or spouses of U.S. citizens or resident aliens who do not have and are not eligible to obtain an SSN.
- Dependents or spouses of non-resident alien visa holders.
If you are required to file a U.S. tax return and do not have an SSN, you will likely need an ITIN. This is common for foreign nationals earning income in the U.S., those investing in U.S. real estate, or individuals who are otherwise subject to U.S. tax laws.
What Information and Documents Are Required for Form W-7?
Completing Form W-7 requires careful attention to detail and the submission of specific supporting documents to verify your identity and foreign status. The IRS needs to be certain of your identity and that you genuinely require an ITIN for a U.S. tax purpose.
Identity Verification Documents
You must provide original or certified copies of documents that prove your identity and foreign status. The IRS requires one document that shows your photograph and one document that shows your name and date of birth. Alternatively, you can provide a combination of documents that meet these requirements. Common documents include:
- Passport: This is the preferred document as it typically satisfies both identity and foreign status requirements. It must be valid and not expired.
- National Identity Card: Must show your name, photograph, date of birth, and expiration date.
- U.S. Driver's License: A valid U.S. driver's license can be used.
- Birth Certificate: For applicants under 18, a birth certificate can be used, but it must be accompanied by another identifying document.
- Foreign Driver's License: This is acceptable.
- Foreign Military Identification Card: Valid for identification.
- U.S. Military Identification Card: Such as DD-214.
- Foreign Voter's Registration Card: If it contains sufficient identifying information.
- Civilan I.D. card: Issued by a foreign government, must contain name, photograph, address, date of birth, and expiration date.
- Visa: If applicable and valid.
- State Department Identification Card: Issued by the U.S. State Department.
- Immigration Naturalization Service (INS) or U.S. Citizenship and Immigration Services (USCIS) photo identification: Such as an Alien Registration Card.
Proof of Foreign Status
While a passport often serves this purpose, other documents can establish foreign status if your primary identity document does not. These might include a visa or other immigration documents that clearly indicate your non-U.S. residency status.
Tax Reason for ITIN
Crucially, you must also demonstrate why you need an ITIN. This is typically proven by submitting a valid U.S. federal income tax return with your Form W-7. If you are applying for an ITIN solely to claim treaty benefits or for other specific tax purposes not directly tied to filing a return in the current year, you must provide documentation supporting that specific tax need. Examples include:
- A completed Form 1040-NR, U.S. Nonresident Alien Income Tax Return.
- Documentation for claiming tax treaty benefits.
- Information related to other U.S. tax reporting requirements, such as for a U.S. business entity.
If you are forming a U.S. LLC and need an ITIN for the entity, or if you are an individual needing to report certain transactions, an ITIN might be required. For example, individuals who are the sole member of a U.S. LLC and are foreign nationals may need an ITIN to file Form 5472, Information Return of a 25% Foreign-Owned U.S. Corporation or a Foreign Corporation Engaged in a U.S. Trade or Business. Opening a U.S. bank account as a non-resident often requires an ITIN, although some banks may have alternative procedures or require an EIN instead. If you are seeking an EIN for your business, you would file Form SS-4, Application for Employer Identification Number, which is a different process and purpose than obtaining an ITIN.
How to File Form W-7
You have several options for submitting your Form W-7 application. The method you choose can affect the processing time and how quickly you receive your ITIN.
1. Mail Your Application Directly to the IRS
You can mail your completed Form W-7, along with your original or certified proof of identity documents and your tax return (or other documentation of tax necessity), to the IRS's ITIN Operation address in Austin, Texas. The IRS will review your application, verify your documents, and mail your ITIN back to you. Your original documents will also be returned, though this can take several weeks. The IRS generally processes these applications within 7 to 11 weeks, but this timeframe can fluctuate based on IRS workload.
2. Apply Through a Certified Acceptance Agent (CAA)
This is often the most convenient method. Certified Acceptance Agents (CAAs) are individuals or entities authorized by the IRS to help taxpayers apply for ITINs. When you apply through a CAA, such as itin.net, you submit your Form W-7 and supporting documents to the agent. The CAA will review your application for completeness and accuracy, and most importantly, they can verify your original identification documents on your behalf. This means you can submit copies of your documents to the CAA, and they will send the originals to the IRS. Crucially, CAAs return your original documents to you immediately after verification, eliminating the risk of losing them in the mail. The CAA then forwards your completed application to the IRS. This process can sometimes lead to faster processing, and it significantly reduces the anxiety of mailing irreplaceable documents.
3. Apply Through an IRS Taxpayer Assistance Center (TAC)
Certain IRS Taxpayer Assistance Centers (TACs) offer ITIN application services. You can make an appointment at an IRS TAC to have your application reviewed and your identification documents verified. However, not all TACs provide this service, and availability can be limited. It is essential to check with your local TAC to confirm if they offer ITIN application assistance and to schedule an appointment in advance.
What Happens After You Apply?
Once the IRS receives and processes your Form W-7 application, they will issue you an ITIN. You will receive a notice from the IRS, typically IRS Letter CP-565, which officially assigns your ITIN. This letter is important and should be kept in a safe place, as it contains your unique nine-digit number.
Your ITIN will be valid for seven years from the date of issuance. If you do not use your ITIN on a federal tax return for three consecutive tax years, the IRS may revoke it. If you need to renew your ITIN or if it has been revoked due to non-use, you will need to reapply using Form W-7 and provide updated documentation.
It is vital to use your ITIN correctly on all future U.S. tax filings. If you are forming a U.S. LLC or planning to conduct business in the U.S., you may also need an Employer Identification Number (EIN) for your business. While an ITIN is for individuals, an EIN is for business entities. You can learn more about obtaining an EIN by visiting our EIN application service page.
Common Mistakes to Avoid
When applying for an ITIN using Form W-7, several common mistakes can lead to delays or rejection of your application. Being aware of these pitfalls can streamline the process:
- Incomplete Application: Failing to fill out all required fields on Form W-7 or omitting necessary information.
- Missing or Incorrect Documentation: Not providing the correct type of identification documents, submitting expired documents, or failing to provide enough proof of identity and foreign status. Remember, the IRS requires original or certified copies.
- No Tax Identification Number Justification: Forgetting to include a valid U.S. federal income tax return or other documentation demonstrating the need for an ITIN. The IRS will not issue an ITIN without a valid tax-related reason.
- Incorrectly Certified Documents: If you are not using a CAA, ensure that any certified copies of documents are indeed certified by the issuing agency (e.g., the agency that issued your passport or birth certificate). Copies certified by notaries public or other non-issuing authorities are generally not accepted.
- Mailing Original Documents without a CAA: While you can mail originals, many applicants prefer to use a CAA to avoid the risk of losing irreplaceable documents during transit.
Cost and Timeline
There is no fee charged by the IRS to apply for an ITIN. The Form W-7 application itself is free. However, if you use a Certified Acceptance Agent (CAA) or a third-party service provider, they may charge a fee for their assistance. These fees vary by provider.
The processing time for an ITIN application can vary significantly. Generally, the IRS aims to process applications within 7 to 11 weeks from the date of receipt. However, during peak tax seasons or periods of high application volume, this timeline can extend. Applying early in the year, well before the tax filing deadline, is advisable. Using a CAA can sometimes expedite the process, as they are familiar with IRS requirements and can ensure your application is complete from the start, potentially reducing back-and-forth.
How to Get Help
Navigating the ITIN application process can be complex, especially for those unfamiliar with U.S. tax forms and procedures. The IRS provides resources, but direct assistance can be invaluable.
Certified Acceptance Agents (CAAs)
As mentioned, CAAs are excellent resources. They are trained by the IRS to assist with Form W-7 applications and can verify your original documents. Using a CAA, like itin.net, can provide peace of mind and help ensure your application is processed correctly the first time. They can also guide you through the necessary documentation and help you understand the tax reason for your ITIN.
Tax Professionals
If your tax situation is complex, or if you have questions about your U.S. tax obligations beyond just obtaining an ITIN, consulting with a qualified tax professional or CPA is recommended. They can advise on tax filing requirements, treaty benefits, and other U.S. tax matters. For general guidance on ITINs, the itin.net author page provides insights from an ITIN specialist.
IRS Resources
The IRS website (irs.gov) offers publications and instructions for Form W-7. You can also contact the IRS directly with specific questions about your application status, though wait times can be long. They also offer services through their Taxpayer Assistance Centers (TACs) by appointment.
In summary, while the direct answer to which form does a taxpayer file to get an itin is Form W-7, successfully obtaining an ITIN involves careful preparation of supporting documents and understanding the correct submission method. Whether you choose to mail your application directly, use a Certified Acceptance Agent, or visit an IRS TAC, ensure all requirements are met to avoid delays.
