Individual Taxpayer Identification Number (ITIN)

An ITIN (Individual Taxpayer Identification Number) is a tax processing number issued by the Internal Revenue Service (IRS) to foreign visitors who must have an identification number for IRS purposes, but who do not already have and are not eligible to receive a Social Security Number.

These persons are generally either certain individuals in the U.S. who are non-immigrants for Immigration and Naturalization purposes or foreign individuals outside the U.S. who are claiming the benefit of an income tax treaty on U.S.-source income.

    An ITIN is used for IRS purposes only and does NOT:

  • impact an individual’s immigration status;
  • give an individual the right to work in the U.S.;
  • entitle an individual to Social Security benefits or the Earned Income Tax Credit.

Please Note: UBPP 2180 requires foreign recipients of Honraria, Royalty, or other payments that are tax reportable have an ITIN or an Social Security Number before payment can be approved.
