Social Security

Social Security tax (FICA) is 6.2% of wages up to the annual wage base ($184,500 in 2026). Both employee and employer pay this amount; this calculator shows the employee portion.

Medicare

Medicare tax is 1.45% on all wages with no cap. High earners pay an additional 0.9% on wages above $200,000 (single) or $250,000 (married filing jointly).

How the Paycheck Estimate Works

The calculator applies a transparent gross-to-net workflow using the tax tables bundled with the site: 2026 federal brackets, 2026 FICA values, and state tax data that is versioned separately.

Full methodology

1. Start with gross pay

Annual salary is divided by the selected pay frequency to estimate weekly, biweekly, semi-monthly, or monthly gross pay.

2. Estimate income tax

Federal and state taxable income are reduced by standard deductions where available, then flat or progressive brackets are applied.

3. Add FICA

Social Security is capped at the wage base, Medicare applies to all wages, and Additional Medicare tax applies above filing-status thresholds.

4. Show take-home pay

The tool subtracts estimated federal, state, Social Security, and Medicare taxes from gross pay and shows annual, monthly, and per-check net pay.

The estimate excludes local income taxes, pre-tax benefit elections, itemized deductions, tax credits, W-4 extra withholding, garnishments, and employer-specific payroll rules.

Data Sources and Review Process

Tax rates are stored in versioned JSON files and should be checked against official federal, FICA, and state sources during each annual update. Federal and FICA values are current for 2026; state data is versioned separately.
