Numbers Needed

By January 5, 2016November 28th, 2018Employment Law, Hiring, Payroll

A Taxpayer Identification Number (TIN) is an identification number used by the IRS in the administration of tax laws. It is issued either by the SSA or by the IRS. A Social Security number (SSN) is issued by the SSA and all other TINs are issued by the IRS.

U.S. citizens and lawful aliens must use a SSN on their employment tax forms. Nonresidents and resident aliens may have an Individual Taxpayer Identification Number (ITIN), but that may not be used for employment purposes. It can be tricky to distinguish a SSN from an ITIN since both are nine digit numbers. However, an ITIN always begins with a nine and has either a seven or an eight as the fourth digit:

9XX-7X-XXXX or 9XX-8X-XXXX

In short, if an employee doesn’t have a SSN, they cannot work.
