How This Works
This calculator applies the federal marginal tax brackets to your taxable income (gross income minus deduction).
Each dollar of income is taxed at the rate for its bracket — not your top rate. That's why your effective rate is lower than your marginal rate.
This estimates federal income tax only. It does not include:
- State or local income tax
- FICA (Social Security + Medicare)
- Self-employment tax
- Tax credits (Child Tax Credit, EITC, etc.)
- Capital gains or investment income
