ITIN Application Guide for Non-Resident Aliens

Welcome to Your Guide on Navigating ITIN Application for Non-Resident Aliens

The Individual Taxpayer Identification Number (ITIN) is a critical tool issued by the Internal Revenue Service (IRS) to individuals who require a U.S. taxpayer identification number but do not qualify for a Social Security Number (SSN).

Why Do You Need an ITIN?

An ITIN is essential for non-resident aliens with federal tax obligations in the U.S. who do not qualify for a SSN. This includes individuals earning income in the U.S., needing to file a U.S. tax return for compliance, and those requiring identification for financial services.

Eligibility for an ITIN

ITINs are available to both resident and nonresident aliens with a U.S. filing or reporting requirement, regardless of their immigration status.

How to Apply for an ITIN

Applicants can apply for an ITIN by filing a Form W-7, along with required documentation proving identity and foreign status. This can be done in advance of or alongside filing a U.S. tax return.

Key Documents and Information Required

  • Completed and signed Form W-7
  • Federal tax return (1040 NR)
  • Proof of identity and foreign status (e.g., passport)

When to Apply

Submit your ITIN application as soon as you have a filing or reporting requirement to avoid tax complications. Applications are accepted throughout the year.

ITIN Validity and Renewal

ITINs are valid for five years and must be used at least once in three years to avoid expiration.
