Full Definition Of Taxpayer Identification Number (Tin)

A taxpayer identification number (TIN) is a unique nine-digit number provided by the Internal Revenue Service (IRS) to individuals or entities for tax-related purposes. TINs are essential for filing tax returns or claiming treaty benefits, as they help identify and monitor taxpayers. There are various types of TINs, such as the Social Security Number (SSN), Employer Identification Number (EIN), Individual Taxpayer Identification Number (ITIN), Taxpayer Identification Number for Pending U. S. Adoptions (ATIN), and Preparer Taxpayer Identification Number (PTIN). The SSN is issued by the Social Security Administration (SSA), while the IRS issues all other TINs.

These examples demonstrate the role of TINs in identifying and tracking taxpayers for tax-related matters.
