What Is An ITIN
An Individual Taxpayer Identification Number (ITIN) is a tax processing number issued by the Internal Revenue Service. It is a nine-digit number that always begins with the number 9.
The 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 U.S. tax return filing responsibilities under the Internal Revenue Code.
Individuals must have a filing requirement and file a valid federal income tax return to receive an ITIN, unless they meet an exception.
