PA Paycheck Tax Calculator 2025-2026
Calculate payroll withholding tax for Pennsylvania, including federal, state, Social Security, and Medicare taxes.
Our free pa paycheck tax calculator helps you calculate payroll withholding taxes for Pennsylvania. This pa paycheck tax calculator estimates federal income tax, Pennsylvania state tax, Social Security, and Medicare withholdings based on your gross pay, pay period, and filing status.
The calculator uses Pennsylvania's flat tax rate of 3.07% to calculate state income tax on your annual income. Federal income tax is calculated separately using 2025-2026 federal brackets and standard deductions ($15,750 single, $31,500 married filing jointly). Social Security tax is calculated at 6.2% on wages up to $176,100, and Medicare tax is 1.45% on all wages, plus an additional 0.9% for high earners (income over $200,000 single or $250,000 married). Your gross pay is first converted to annual income based on your pay period (weekly × 52, bi-weekly × 26, monthly × 12). All taxes are then calculated on the annual amount and converted back to your pay period. Your net take-home pay is your gross pay minus all these taxes combined.
Annual Income: Annual Income = Gross Pay × Pay Period Multiplier (52 for weekly, 26 for bi-weekly, 12 for monthly)
Federal Tax: Taxable Income = Annual Income - Standard Deduction. Tax calculated using progressive brackets (10%, 12%, 22%, 24%, 32%, 35%, 37%)
Pennsylvania State Tax: State Tax = Annual Income × 3.07%
Social Security: Social Security = min(Annual Income, $176,100) × 6.2%
Medicare: Base = Annual Income × 1.45%. Additional = max(0, Annual Income - Threshold) × 0.9%
Total Withholding: Total = Federal Tax + State Tax + Social Security + Medicare
Net Pay: Net Pay = Gross Pay - (Total Withholding / Pay Period Multiplier)
