The Tax Identification Number: An Overview (TIN)

A tax identification number is a series of numbers that distinguishes individuals, corporations, and other entities such as non profits (NPOs). A tin number must be applied for by each individual or entity. The assigning agency assigns the applicant a unique number once they have been approved.

The TIN, also known as a taxpayer identification number, is required for anyone who files annual tax returns with the IRS and is used by the agency to trace taxpayers. When claiming government benefits or services, filers must submit the number of tax-related papers. 2

TINs are also required for the following reasons:

  • For credit: Social Security numbers are required on credit applications by banks and other lenders. This information is subsequently sent to the credit bureaus to ensure that the application is being filled out by the correct person. TINs—particularly SSNs—are also used by credit reporting companies to report and track an individual’s credit history.
  • For employment: Employers require a Social Security number from anyone applying for an employment. This is done to ensure that the individual is legally authorised to work in the United States. The numbers are double-checked by employers with the issuing agency.


  • For state agencies: Businesses must have state identification numbers in order to file tax returns with their respective state tax agency. The filer receives the I.D. number immediately from the state taxing authority.

There are numerous types of tax identification numbers, sometimes known as taxpayer identification numbers. Individuals are given TINs in the form of Social Security numbers (SSNs), whereas businesses (such as corporations and partnerships) are given employment identification numbers (EINs) (EINs).
