Individual Taxpayer Identification Number (ITIN)

What Is an Individual Taxpayer Identification Number (ITIN)?

An Individual Taxpayer Identification Number (ITIN) is a tax processing number issued by the IRS to individuals who are required to file taxes but are not eligible for a Social Security Number (SSN).

Why It Matters

ITINs allow individuals, including nonresident and undocumented individuals, to comply with tax laws. It also enables access to certain financial services, such as opening bank accounts or applying for loans.

How ITIN Works

The process includes:

  • applying through the IRS using Form W-7
  • providing identity and residency documentation
  • receiving a nine-digit number
  • using the ITIN for tax filing and reporting

ITINs do not provide work authorization or immigration status.

Example

A nonresident individual working in the U.S. files taxes using an ITIN instead of an SSN.

ITIN vs SSN

  • ITIN is for tax purposes only.
  • SSN is used for employment, benefits, and identification.
