How to Apply for an ITIN for Foreigners

Applying for an Individual Taxpayer Identification Number (ITIN) is a crucial step for foreigners needing to meet U.S. tax obligations without a Social Security Number. While the process can appear complex due to specific requirements, it is essential for compliance with IRS regulations.

Understanding the application process helps individuals handle their tax responsibilities effectively. Below, we outline how to apply for an ITIN, focusing on eligibility, required documentation, and the filing process.

Eligibility and Non-Eligibility Criteria

An ITIN is issued to individuals who cannot obtain a Social Security Number (SSN) but have a U.S. tax filing requirement. This includes non-resident aliens filing a U.S. tax return, resident aliens under the substantial presence test, and dependents or spouses of U.S. citizens or resident aliens. Foreign nationals earning income from U.S. sources, such as rental or investment income, may also qualify.

Individuals eligible for an SSN cannot apply for an ITIN. The ITIN is strictly for tax purposes and does not authorize work or provide Social Security benefits. Misusing an ITIN can result in penalties and complications with the IRS.

Documentation for Application

To obtain an ITIN, applicants must provide documentation verifying identity and foreign status. A valid passport is the preferred document, as it satisfies both requirements. If unavailable, two other documents from the IRS-approved list, such as a foreign driver’s license or national identification card, must be submitted.

Documents must be original or certified copies from the issuing agency. Notarized copies are not accepted. Dependents may need to provide additional documentation, such as birth certificates or medical records, to meet verification requirements. The IRS’s strict verification process is designed to prevent fraud and ensure accurate identification.

ITIN applications are typically submitted with a tax return unless an exception applies, such as claiming treaty benefits or being a non-resident alien student. Exceptions are detailed in the IRS instructions for Form W-7.

Filing Process

The ITIN application process begins with completing Form W-7. Accuracy is critical, as errors can cause delays or rejections. The information provided must match the supporting documents submitted.

Form W-7 is usually attached to the corresponding tax return, unless an exception applies. The tax return must be signed, dated, and include all required schedules and forms to avoid processing delays.

Applicants can mail the completed Form W-7 and tax return to the IRS ITIN Operations center in Austin, Texas. Alternatively, they can apply in person at an IRS Taxpayer Assistance Center or through an IRS-authorized Certifying Acceptance Agent (CAA), who can verify documents and forward the application.

Renewal Requirements

ITINs must be renewed if they have not been used on a federal tax return for three consecutive years. ITINs with middle digits “70” through “88,” “90” through “99,” or specific sequences assigned before 2013 also expire. Staying informed about these details helps avoid tax processing delays.

Renewing an ITIN requires submitting a new Form W-7 along with the necessary identification documents. A tax return is not required for renewal, simplifying the process. The IRS typically opens the renewal period before tax season, encouraging early submission.

Tax Filing With an ITIN

An ITIN is essential for meeting U.S. tax obligations, including reporting income and claiming certain tax credits. It does not authorize work or qualify the holder for Social Security benefits. Accuracy in tax filings is critical, as errors can lead to delays or rejections.

Certain tax credits and deductions are available to ITIN holders if eligibility criteria are met. For instance, the Child Tax Credit (CTC) is available if dependents have valid Social Security Numbers. ITIN holders classified as residents for tax purposes under the substantial presence test may qualify for deductions such as education or medical expenses. However, they are not eligible for the Earned Income Tax Credit (EITC), which requires a valid SSN.

ITIN holders must adhere to tax deadlines and be aware of estimated tax payment requirements for income not subject to withholding, such as rental or self-employment income. Accurate recordkeeping is essential for substantiating income and deductions during audits or inquiries. Professional tax preparation services or IRS resources can help ensure compliance and accurate filings.
