A Taxpayer Identification Number (TIN) is an identification number used by the Internal Revenue Service (IRS) in the administration of tax laws:
  • Social Security Number (SSN): For sole proprietors, the business identification number may be the same as the individual’s Social Security Number (SSN) or TIN, if applicable.
  • Federal Identification Number (FIN, a.k.a. EIN): A FIN is required for all partnerships, corporations, and LLCs (single-member LLCs without a FIN may use a SSN). This number is obtained from the Internal Revenue Service.
  • Individual Taxpayer Identification Number (ITIN): An ITIN is a tax processing number only available for certain nonresident and resident aliens, their spouses, and dependents who cannot get an SSN.
