FAQ
- What income should I enter?
- Enter your taxable income — the amount that remains after deductions such as the standard deduction. This calculator applies the federal brackets directly to that figure and does not subtract deductions for you.
- What is the difference between effective and marginal rate?
- Your marginal rate is the rate on your next dollar of income (the bracket your income tops out in). Your effective rate is total tax divided by taxable income — it is lower because earlier dollars are taxed at lower bracket rates.
- Is this tax advice?
- No. This is an estimate using 2024 US federal income tax brackets only. It excludes state taxes, credits, FICA, and other factors, and is not tax advice. Consult a professional for your situation.
