Estimate your US federal income tax based on filing status, income, and current tax brackets.

Our free Tax Bracket Calculator lets you estimate your US federal income tax based on filing status, income, and current tax brackets.

Tax Bracket Calculator runs entirely in your browser on CalculatorsPlus — enter your values, get instant results, and copy or share your output in one click. Your data never leaves your device; we do not store inputs on any server.

Financial planning starts with understanding the numbers behind tax bracket calculator scenarios. Adjust inputs to compare options side by side — for example, how a 0.5% rate change or an extra monthly payment affects your total cost over time.

Results update in real time as you change inputs, so you can explore "what if" scenarios — adjust one variable at a time to see how it affects the outcome before committing to a purchase, plan, or decision.

This page includes step-by-step instructions, frequently asked questions, and practical tips below the calculator. Bookmark it for repeat use — many finance tasks come up weekly during projects, studies, or financial planning.

Frequently Asked Questions

How do US tax brackets work?
The US uses a progressive tax system. You pay different rates on different portions of your income — only income within each bracket is taxed at that bracket's rate.
What is marginal vs. effective tax rate?
Your marginal rate is the rate on your last dollar of income (your highest bracket). Your effective rate is the total tax divided by total income — it is always lower than the marginal rate.
What are the current federal tax brackets?
As of 2024, federal brackets are 10%, 12%, 22%, 24%, 32%, 35%, and 37%. The income ranges depend on your filing status (single, married, head of household).
Does this include state taxes?
This calculator estimates federal income tax only. State income tax rates vary — some states have no income tax (TX, FL, WA), while others have rates up to 13%+.
