What is a TIN Number? 

TIN stands for Taxpayer Identification Number. Composed of nine digits, a TIN is an identification number that is used by the Internal Revenue Service (IRS) in the administration of tax laws. Except for Social Security Numbers which are issued by the Social Security Administration, tax identification numbers are issued by the Internal Revenue Service (IRS).

If you are wondering if you need a TIN, it is required when filing tax returns and when claiming treaty benefits. Additionally, a TIN is a must when completing other statements, withholding certificates, and other tax-related documents.
