Federal Income Tax Withholding
Federal income tax withholding is based on your filing status, allowances, and the IRS withholding tables. This calculator uses a simplified approximation based on the 2026 tax brackets and the annualized pay method. For more precise withholding, use the IRS Tax Withholding Estimator.
Social Security (OASDI)
The Social Security tax rate for employees is 6.2% of wages up to the 2026 wage base of $184,500. This matches the employer's share, for a total combined rate of 12.4%.
Medicare (HI)
The Medicare tax rate for employees is 1.45% of all wages with no wage base limit. This matches the employer's share, for a total combined rate of 2.9%.
Additional Medicare Tax
An Additional Medicare Tax of 0.9% applies to wages over $200,000 ($250,000 for married filing jointly). This tax is employee-only — the employer does not match it.
How the Calculator Works

- Calculate Federal Income Tax: Based on filing status, allowances, and 2026 tax brackets.
- Apply Post-Tax Deductions: Subtract Roth 401(k) and other after-tax deductions.
- Calculate Net Pay: Gross pay minus all taxes and deductions.
