Payroll Tax Calculator (2025-2026)
Calculate net pay by deducting Federal Tax, Social Security, and Medicare from gross wages for the 2025-2026 tax year.
Our payroll tax calculator helps you understand how to calculate payroll taxes for 2025-2026 by deducting federal tax, Social Security (6.2%), and Medicare (1.45%) from gross wages. Enter your gross pay, pay period, and filing status for instant net pay calculations.
The calculator first converts your gross pay to annual income based on your pay period. It then calculates federal income tax using 2025-2026 tax brackets and standard deductions ($15,750 single, $31,500 married, $23,625 head of household). 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). If you select a state, state income tax is also calculated. Finally, all taxes are converted back to your pay period and deducted from gross pay to show your net pay.
All calculations are performed on an annual basis first, then converted back to your selected pay period. Weekly pay is multiplied by 52, bi-weekly by 26, monthly by 12, and annual remains as-is. This ensures accurate tax calculations regardless of pay frequency.
Federal Tax: Taxable Income = Gross Income - Standard Deduction. Tax is calculated using progressive brackets (10%, 12%, 22%, 24%, 32%, 35%, 37%).
Social Security: Tax = min(Annual Income, $176,100) × 6.2%
Medicare: Base Tax = Annual Income × 1.45%. Additional Medicare = max(0, Annual Income - Threshold) × 0.9% where Threshold is $200,000 (single) or $250,000 (married).
Net Pay: Net Pay = Gross Pay - (Federal Tax + Social Security + Medicare + State Tax) / Pay Period Multiplier
