Quick Answer
This tax calculator estimates your federal income tax using current progressive brackets and standard deduction. Enter your income and filing status to see total tax, effective rate, marginal rate, and bracket-by-bracket breakdown.
How to Use This Tax Calculator
Enter your annual gross income, select your filing status (Single or Married Filing Jointly), and choose whether to use the standard deduction. This tax calculator uses current federal tax brackets to estimate your total income tax, effective tax rate, marginal rate, and take-home pay. The bracket breakdown shows how much tax you pay in each bracket.
How Federal Income Tax Brackets Work
The US uses a progressive tax system. You don't pay a single rate on all income — different portions are taxed at increasing rates. The standard deduction reduces your taxable income. Your effective tax rate (total tax ÷ income) is always lower than your marginal rate (the rate on your last dollar earned). Use this calculator to see how bracket thresholds affect your tax bill.
