A taxpayer identification number (TIN) is used by the Internal Revenue Service (IRS) and by the Franchise Tax Board (FTB) in the administration of payroll tax laws. Other types of TINs are issued by governments for non-payroll tax administration such as state Sales Taxes, state E-waste taxes, county Property taxes, and foreign Value Added Taxes.

Individuals must have a TIN if they are either employed by UCSB , or they are receiving a  payment from UCSB for services, taxable awards, or taxable scholarship/fellowship grants (such as a monthly or quarterly stipend). An individual is not eligible for employment in the USA unless  they have an Individual Taxpayer ID (ITIN) number or Social Security number (SSN).

UCSB has a Federal Employer Identification Number (EIN), and a state employer payroll tax account number, also known as a State Employer Identification Number (SEIN). UCSB has other TINs including a California Department of Tax & Fee Administration (CDTFA) Sales Tax Account number, a CDTFA E-Waste account number, and several county property tax account numbers.
