What Are SUI Taxable Wage Bases?
SUI taxable wage bases set the maximum amount of an employee’s earnings that are subject to state unemployment taxes. For example, if your state’s wage base is $12,000, employers only pay SUI taxes on the first $12,000 of each employee’s wages.
These wage bases are essential for funding unemployment benefits, serving as a safety net for workers laid off through no fault of their own. Most states adjust their wage bases annually to reflect economic and budgetary conditions.
How Are Taxable Wage Bases Determined?
State governments consider several factors when setting their SUI taxable wage bases:
- Economic Conditions: In times of low unemployment, states often increase wage bases to build reserves for future downturns.
- Trust Fund Solvency: Wage bases are adjusted to ensure unemployment benefits remain sustainable.
- Legislative Actions: Some states index their wage bases to inflation, while others adjust them to meet budgetary or federal requirements.
Understanding these factors can help you anticipate changes and plan for the financial impact.

How To Calculate SUI Contributions
To calculate your SUI tax liability, follow these three steps:
- Determine Your State’s Wage Base: Find the taxable wage base for each state where you employ workers.
- Know Your SUI Tax Rate: This rate depends on your industry and experience rating.
- Multiply Wage Base by Tax Rate: Use this formula for each employee.
Example Calculation:
- State: Illinois
- 2025 Taxable Wage Base: $13,916
- Employer's SUI Tax Rate: 3.4%
- Employee's Annual Wages: $40,000
SUI Tax Liability = Taxable Wages × SUI Tax Rate
SUI Tax Liability = $13,916 × 3.4% = $473.14
The employer would owe $473.14 in Illinois SUI tax for this employee.
