💵 Tax Bracket Calculator
Estimate your U.S. federal income tax using the current progressive tax brackets, plus your marginal and effective tax rate.
How U.S. tax brackets work
The United States uses a progressive federal income tax system, meaning different portions of your income are taxed at different rates as it rises through a series of brackets — your entire income is not taxed at a single rate.
How this calculator works
Using 2025 IRS tax bracket thresholds for Single or Married Filing Jointly status, this calculator applies each bracket’s rate only to the portion of income that falls within it, then sums the results. It also shows your marginal rate (the rate on your last dollar earned) versus your effective rate (total tax as a percentage of total income).
This is a simplified estimate using standard federal brackets only — it does not include deductions, credits, state taxes, or other adjustments. For general planning and education only; consult a tax professional for filing decisions.
