2026 federal withholding
The federal engine uses the standard annual percentage method schedules from IRS Publication 15-T for 2026. The calculator annualizes wages, applies W-4 adjustments, subtracts Step 3 credits, and divides withholding by the selected number of pay periods.
Federal withholding is only one line in a paycheck. FICA, state tax, local wage tax, SDI or paid leave programs, pre-tax deductions, and post-tax deductions can all change net pay.
