📝 Overview
A wage base is the maximum amount of an employee's earnings subject to a specific payroll tax within a calendar year. Understanding how wage bases work helps you anticipate when certain taxes stop being collected and how year-to-date earnings affect your payroll obligations.
🔑 How Wage Bases Work
Each payroll tax that has a wage base limit stops being collected once a worker's year-to-date earnings reach that limit. Neither you nor the worker owes that tax for the remainder of the calendar year.
At the start of each new calendar year, the count resets and the tax applies again until the wage base is reached.
💡 If a worker changes jobs during the year, the wage base limit restarts with their new employer. Each employer tracks the wage base independently.
📊 Current Year Wage Base Limits for Common Payroll Taxes
The following are the wage base limits for common payroll taxes in the current tax year:
Social Security tax — stops being collected once a worker's earnings reach $176,100
Federal Unemployment Tax (FUTA) — stops at $7,000
State Unemployment Insurance (SUI) — limits vary by state; check your state's current rate
⚠️ Important Note: Wage base limits are updated annually by the IRS and state agencies. Verify current limits each year before running your first payroll.
⚙️ Workers Who Move or Work Across States
If a worker moves to a different state during the year, it can affect how SUI wage bases apply:
If the new state's SUI wage base is lower than the previous state's, no additional SUI taxes are owed in the new state for wages already taxed. There is no refund for SUI taxes already paid in the previous state.
If the new state's SUI wage base is higher, taxes continue until the higher limit is reached. You typically receive a credit for SUI taxes already paid on wages from the previous state.
Almost every state, except Minnesota and Louisiana, allows employers to apply wages paid in other states when calculating unemployment taxes. This prevents the same wages from being taxed twice across state lines.

Does the wage base limit apply to all payroll taxes?

No. Not all payroll taxes have a wage base limit. Medicare tax, for example, applies to all wages with no cap. The wage base limit applies specifically to Social Security tax, FUTA, and SUI, among others. Some states also have additional taxes with their own limits.
What happens to Social Security tax after a worker hits the wage base?

Once a worker's year-to-date earnings reach the Social Security wage base limit for the current year, Social Security tax stops being withheld from their pay for the rest of the calendar year. Both the employee and employer portions stop at the same time. The deduction automatically resumes at the start of the next calendar year.
Do wage base limits reset if a worker is rehired?

If a worker is rehired by the same employer within the same calendar year, their year-to-date earnings typically carry over and the wage base limit does not reset. If they are hired by a different employer, that new employer starts tracking the wage base from zero for that worker, regardless of what was earned with the previous employer.
Where can I find the current SUI wage base for my state?

SUI wage base limits are set by each state and can change annually. Check with your state's workforce or unemployment agency for the current limit. You can also verify current rates through the DaySmart Payroll platform or by contacting DaySmart Support.
How does the wage base affect my costs as an employer?

Employer-side taxes like FUTA and the employer portion of Social Security stop accumulating once a worker's wages reach the applicable wage base. This means your payroll tax costs for high-earning workers decrease partway through the year. It is worth factoring this into cash flow planning, particularly for businesses with workers who reach wage base limits early in the year.
