A U.S. Individual Taxpayer Identification Number (ITIN) is issued by the Internal Revenue Service (IRS) to individuals who need a U.S. taxpayer identification number but do not have, and are not eligible to obtain, a Social Security number (SSN). The primary reason for needing an ITIN is to comply with U.S. tax filing obligations. Eligibility for an ITIN is based on specific criteria set forth by the IRS, primarily related to U.S. tax law requirements. This guide details who is eligible for an ITIN and the circumstances under which an application is necessary.
Who is Eligible for an ITIN?
An ITIN is available to individuals who are neither U.S. citizens nor U.S. resident aliens, but who have U.S. tax obligations or are filing certain U.S. tax returns. The IRS issues ITINs for various purposes, all stemming from a U.S. tax requirement. The question of "who is eligible for an ITIN" is answered by examining these specific IRS-defined scenarios. If you fall into one of these categories and do not have an SSN, you likely qualify for an ITIN.
Non-Resident Aliens Filing U.S. Tax Returns
This is the most common category. Non-resident aliens who are required to file a U.S. federal income tax return (such as Form 1040-NR, U.S. Nonresident Alien Income Tax Return) but cannot obtain an SSN are eligible. This includes:
- Non-resident aliens earning U.S. source income that is subject to U.S. income tax withholding, even if they are claiming treaty benefits to reduce or eliminate that withholding. The filing of Form 1040-NR is often necessary to claim these treaty benefits.
- Non-resident aliens who are engaged in a trade or business in the United States and are required to file a U.S. tax return.
Resident Aliens Filing U.S. Tax Returns
While generally resident aliens are eligible for SSNs, there are exceptions. If a resident alien is not eligible for an SSN (e.g., due to immigration status or other reasons preventing SSN issuance) but has a U.S. tax filing requirement, they may apply for an ITIN.
Dependents or Claimants of Dependents
An individual who can be claimed as a dependent or as a qualifying child on someone else's U.S. federal income tax return may need an ITIN if they are not eligible for an SSN. This is common for foreign students or children of U.S. expatriates who do not meet the criteria for an SSN.
Dependents or Claimants of Dependents in Tax Treaty Cases
If a dependent is a dependent on a U.S. taxpayer's return and is a citizen or resident of a country with a tax treaty with the U.S., and the taxpayer is claiming treaty benefits on behalf of that dependent, an ITIN may be required for the dependent.
Individuals Claiming Tax Treaty Benefits
Individuals who are not U.S. residents but are entitled to claim tax treaty benefits, such as reduced tax rates on certain types of U.S. income, must generally file a U.S. tax return (Form 1040-NR) to claim these benefits. If they do not have an SSN, they will need an ITIN to do so.
Individuals Opening a U.S. Bank Account
While not a tax filing requirement, certain financial institutions in the U.S. may require an ITIN from non-resident aliens who wish to open a U.S. bank account. This is not an IRS requirement for ITIN issuance, but rather a bank policy. The IRS will issue an ITIN for this purpose only if the applicant provides a valid reason for needing the ITIN, and opening a bank account alone is typically not sufficient unless it's tied to a specific U.S. tax reporting requirement. However, many non-residents seeking to establish a U.S. business presence will need both an ITIN and potentially an EIN. Applying for an EIN, or Employer Identification Number, is a separate process for businesses that can be initiated by non-residents, and it often requires a U.S. address. You can learn more about obtaining an EIN on our /ein service page.
Individuals Owning a U.S. LLC
Foreign individuals who own or are involved with a U.S. Limited Liability Company (LLC) may need an ITIN. If the LLC is a single-member LLC owned by a non-resident alien, and that LLC has U.S. tax reporting requirements, such as filing Form 5472, Information Return of a 21st Century State Taxpayer With a Reportable U.S. Transaction, the owner may need an ITIN. A U.S. LLC typically requires an EIN for its own tax filings, but the foreign owner might need an ITIN for personal tax obligations related to the LLC's income. Forming a U.S. LLC is a common step for foreign nationals looking to invest or do business in the U.S., and this process often involves obtaining an EIN and potentially an ITIN. Our /llc service covers the intricacies of U.S. LLC formation for non-residents.
Other Specific IRS Requirements
There are other less common situations where an ITIN might be necessary, such as:
- Individuals applying for a U.S. passport when they are not eligible for an SSN.
- Individuals who are required to file Form 1042-S, Foreign Person's U.S. Source Income Subject to Withholding, and are not eligible for an SSN.
- Individuals who are receiving U.S. financial assistance or scholarships and are required to report this income on a U.S. tax return.
What Documents Are Needed to Apply for an ITIN?
To apply for an ITIN, you must submit Form W-7, Application for IRS Individual Taxpayer Identification Number, along with original or certified copies of required identification documents and proof of foreign status. The IRS requires at least one document that proves both identity and foreign status. Common documents include:
- Passport: This is the preferred document as it establishes both identity and nationality.
- National Identity Card: Must show name, photograph, address, date of birth, and expiration date.
- U.S. Driver's License: Must show name, photograph, date of birth, and current mailing address.
- Foreign Driver's License: Must show name, photograph, date of birth, and expiration date.
- Birth Certificate: Must show name, date of birth, place of birth, and parents' names.
- Foreign Voter's Registration Card: Must show name, address, date of birth, and expiration date.
- U.S. State Identification Card: Must show name, photograph, date of birth, and expiration date.
- Visa: Must show name, photograph, expiration date, and entry date into the U.S.
- Alien Registration Card: Must show name, photograph, and expiration date.
If you cannot provide a passport, you may submit a combination of documents to prove identity and foreign status. For example, a birth certificate (for foreign status) and a national identity card (for identity).
How to Apply for an ITIN
There are three main ways to apply for an ITIN:
- Mail your application to the IRS: You can mail your completed Form W-7, along with original or certified copies of your identification documents, and your federal tax return to the IRS address listed in the Form W-7 instructions. The IRS will review your application and mail your ITIN to you. Your original identification documents will be returned to you, but this process can take several weeks or months.
- Apply through a Certified Acceptance Agent (CAA): A CAA is an individual or entity authorized by the IRS to help taxpayers apply for ITINs. CAAs can verify your original identification documents and forward your Form W-7 application to the IRS on your behalf. This is often a faster and more convenient method, as CAAs can streamline the process. Many CAAs are part of larger organizations, including services like itin.net, which assists individuals in navigating this process. Applying via a CAA can significantly reduce the risk of errors on your application and ensure your original documents are returned promptly.
- Visit an IRS Taxpayer Assistance Center (TAC): Some IRS TACs offer ITIN application services by appointment. You must bring original identification documents or certified copies from the issuing agency. You can find a local TAC by using the IRS website locator tool, but it is advisable to call ahead to confirm they offer ITIN application services and to schedule an appointment.
Processing Times and Costs
The IRS does not charge a fee to apply for an ITIN. However, if you use a Certified Acceptance Agent (CAA), they may charge a service fee for their assistance. Processing times can vary significantly. Currently, the IRS estimates that it takes 10–11 weeks to receive an ITIN after mailing your application and tax return. If applying through a CAA, the process might be slightly quicker, as they can handle initial verification. It is essential to apply well in advance of any tax deadlines to ensure you receive your ITIN in time.
Common Reasons for ITIN Application Rejection
Several factors can lead to the rejection of an ITIN application:
- Incomplete Application: Missing information on Form W-7 or failure to provide all required documentation.
- Invalid Identification Documents: Submitting expired documents, photocopies instead of originals or certified copies, or documents that do not meet IRS requirements.
- Lack of a U.S. Tax Filing Requirement: Applying for an ITIN solely to open a bank account without a corresponding tax obligation is generally not sufficient grounds for issuance, unless the bank requires it for specific IRS reporting purposes (like reporting interest income to the IRS).
- SSN Eligibility: If the IRS determines that you are eligible for an SSN, your ITIN application will be denied. You would then need to apply for an SSN through the Social Security Administration.
- Incorrect Tax Return: If the accompanying tax return is not properly filed or is not required.
ITIN Renewal and Expiration
ITINs do not expire automatically if they are used for tax filing purposes. However, the IRS has implemented a renewal program for ITINs that have not been used on a federal tax return for three consecutive tax years. Additionally, ITINs with middle digits 70, 71, 72, and 81 have expired and must be renewed. If your ITIN has expired, you must renew it before filing a tax return that requires it. The renewal process is similar to the initial application, requiring Form W-7 and updated identification documents.
When to Seek Professional Assistance
Navigating the ITIN application process can be complex, especially for individuals unfamiliar with U.S. tax laws or documentation requirements. If you are unsure about your eligibility, the required documents, or the application process, seeking assistance from a qualified professional is highly recommended. Certified Acceptance Agents (CAAs) are specifically trained to help with ITIN applications and can ensure accuracy and efficiency. For complex tax situations, or if you have questions about your U.S. tax obligations beyond just obtaining an ITIN, consulting with a tax advisor or an experienced ITIN specialist is advisable.
