What is the Income Tax Calculator?
This calculator estimates your federal income tax, FICA (Social Security and Medicare), optional state tax, and take-home pay using current-year tax brackets and standard deductions. You can add pre-tax deductions (e.g. 401(k), HSA), choose standard or itemized deductions, and enter tax credits to see how they affect your liability and net pay.
Key Concepts
Marginal vs Effective Rate
Marginal rate is the tax on your last dollar of income. Effective rate is total tax divided by gross income—your average tax burden.
FICA
Social Security (6.2% up to the wage base) and Medicare (1.45%, plus 0.9% additional above a threshold). Applied to wages.
Standard vs Itemized
Take the larger of the standard deduction (by filing status) or your total itemized deductions (e.g. mortgage interest, SALT, charity).
How to Use
- Enter your annual gross income and filing status.
- Optionally add pre-tax deductions, switch to itemized deductions, or enter tax credits.
- Add a state tax rate (optional) for a combined estimate.
- Click 'Calculate Tax' to see federal tax, FICA, take-home pay, bracket breakdown, and charts.
Understanding Results and Charts
The hero card shows annual take-home pay and monthly/bi-weekly equivalents. The doughnut chart shows where your income goes (take-home, federal tax, FICA, state, pre-tax). The tax distribution bar shows federal, Social Security, Medicare, and state amounts. The bracket table shows how much income falls in each tax bracket.
Important Notes
- This is an estimate. Actual tax depends on your full return, credits, and phase-outs.
- Brackets and standard deductions shown are for illustration (e.g. 2024). Use current IRS figures for your year.
- Consult a tax professional for advice specific to your situation.
