These tax calculator estimates use 2026 federal income-tax brackets, 2026 FICA values, and state income-tax data that is versioned separately. They were reviewed on June 2, 2026. Treat results as planning estimates, not tax, payroll, legal, or financial advice.
How This Tax Calculator Works
Core formula
Federal tax + state tax + Social Security + Medicare = estimated total annual tax
Best use case
A salary-based tax estimate combines income tax and payroll tax to show both annual taxes and after-tax income.
Important limits
- Use this page when you want a broad annual tax estimate, not only income tax.
- Results do not automatically include local taxes, tax credits, itemized deductions, or benefit elections.
- Social Security is capped at the 2026 wage base of $184,500.
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.
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.
Tax Calculator FAQ
What does this tax calculator include?
It includes federal income tax, state income tax, Social Security, and Medicare. It is designed for salary-based annual planning rather than a full tax return.
Does this tax calculator show after-tax income?
Yes. Along with the tax total, it estimates net annual income after the modeled federal, state, and payroll taxes are subtracted.
Does it include tax credits or itemized deductions?
No. The estimate primarily relies on standard deductions and published tax rates. Credits, itemized deductions, and local taxes can materially change your actual result.
