    How this calculation works

    Federal income tax is calculated using progressive tax brackets — you pay each rate only on income within that bracket, not on your total income. State income tax rates range from 0% (Texas, Florida) to 13.3% (California). This calculator applies 2026 federal and state rates to your taxable income after standard deductions.

    Effective Tax Rate = Total Tax Liability ÷ Gross Income × 100
