Estimate your 2025 federal income tax bill based on your income and filing status. Fast, free, and no sign-up required.
This calculator uses 2025 federal tax brackets and the standard deduction to estimate your federal income tax. It applies the progressive tax system, meaning only the income in each bracket is taxed at that bracket's rate — not your entire income.
Your marginal rate is the rate on your last dollar of income — your "tax bracket." Your effective rate is your actual average rate across all income. Most people pay a much lower effective rate than their marginal bracket suggests because of how progressive taxation works.
