ITIN Basics

Last updated: 20265 min read

An Individual Taxpayer Identification Number lets certain taxpayers meet federal filing requirements when they are not eligible for a Social Security number.

What an ITIN is and isn't

An ITIN is a tax processing number used for federal tax reporting. It does not provide work authorization, does not change immigration status and is not a form of identification for other purposes.

Who may need one

Individuals with a U.S. filing or reporting requirement who cannot obtain a Social Security number, and in certain cases spouses or dependents listed on a return.

Applications and renewals

Applications generally require a completed application form, supporting identity and foreign status documentation, and often the tax return itself. ITINs can expire if unused for a period of years and may need renewal.

Key takeaways

  • An ITIN exists for tax reporting only.
  • Documentation requirements are specific and strict.
  • ITINs can expire and may require renewal.
  • Credit eligibility rules can differ from SSN filings.
