Yes. Pennsylvania treats bonuses as taxable wages and generally requires Pennsylvania income tax withholding on bonus and other supplemental wage payments. Pennsylvania uses a flat personal income tax rate rather than a progressive state income tax system.
When a bonus is paid, Pennsylvania withholding is generally based on the state’s flat income tax rate. Local earned income tax may also apply depending on the employee’s residence and work location. You can use the calculator above, powered by Beyond HCM, to estimate Pennsylvania withholding and take-home pay for bonus payments. The calculator uses a 2026 estimate based on Pennsylvania withholding guidance and current payroll assumptions.

For 2026:
– Pennsylvania state income tax withholding is generally estimated at 3.07%

Local earned income tax may also apply, depending on where the employee lives or works. Employers should confirm the applicable local tax rate when processing Pennsylvania payroll.
