Frequently Asked Questions
What is the difference between marginal and effective tax rate?▼
Your marginal rate is the tax bracket on your last dollar of income. Your effective rate is your total tax divided by total income — always lower because earlier income is taxed at lower brackets.
Is this for federal taxes only?▼
This calculator estimates federal income tax. State taxes vary widely and are not included. Consult your state's tax authority for state-specific calculations.
