Taxable Wage Base

The Taxable Wage Base is the maximum amount of an employee’s earnings that is subject to a particular payroll tax within a calendar year. Once an employee’s wages exceed this threshold, no additional taxes for that specific payroll tax (such as Social Security or state unemployment insurance) are withheld for the remainder of the year. The wage base varies depending on the tax type and jurisdiction, and it is adjusted annually by governing agencies to account for inflation or policy changes.
