What is a taxpayer identification number?
A taxpayer identification number (TIN) is used by the Internal Revenue Service (IRS) to process all tax-related documents and tax returns. Most United States citizens and permanent residents use their Social Security number as a TIN; the IRS issues special TINs to people who do not qualify for a Social Security number.
Everyone who conducts business with the IRS needs a taxpayer identification number. This includes individuals filing returns, corporations, and limited liability companies. The IRS issues the following special TINs:
- Employer Identification Number (EIN): Issued to businesses, estates, and trusts.
- Individual Taxpayer Identification Number (ITIN): Assigned to nonresident and resident foreign nationals as well as their spouses and children who do not qualify for a Social Security number.
- Adoption Taxpayer Identification Number (ATIN): Granted to individuals adopting a child for whom they cannot obtain a Social Security number before they must file taxes.
- Preparer Tax Identification Number (PTIN): Issued to professional tax preparers to use when preparing returns for other people.
