WHAT IS AN ITIN?

An Individual Taxpayer Identification Number (ITIN) is a tax processing number issued by the Internal Revenue Service. IRS issues ITINs to individuals who are required to have a U.S. taxpayer identification number but who do not have, and are not eligible to obtain a Social Security Number (SSN) from the Social Security Administration (SSA).

ITINs are issued regardless of immigration status because both resident and nonresident aliens may have a U.S. filing or reporting requirement under the Internal Revenue Code.

Frequently Asked Questions

What is an ITIN?

ITIN stands for Individual Taxpayer Identification Number, which is a number assigned by the Internal Revenue Service for tax purposes to individuals who do not have, or are not eligible to have, a Social Security Number in the United States. ITINs are used by individuals without Social Security Numbers for federal tax filing purposes with the IRS.

An ITIN is a nine-digit number beginning with the number “9” and is formatted like a social security number, for example: 912-34-5678.

Individual Taxpayer Identification Numbers are not dependent on immigration status in the USA, because both resident and nonresident aliens in the United States may have federal tax reporting requirements by the IRS.

An ITIN is NOT the same as a SSN and does not give the same benefits. It is for U.S. Federal income tax filing purposes only.
