1. Understanding Federal Income Tax Brackets
Federal income tax is calculated using a graduated system with rates of 10%, 12%, 22%, 24%, 32%, 35%, and 37%. Our tax bracket calculator helps you find which bracket your taxable income falls into and estimates your marginal and effective tax rates based on the latest IRS thresholds.
2. Marginal Tax Rates vs. Effective Tax Rates
Your marginal rate is the tax percentage applied to the last dollar you earn (your highest bracket). Your effective tax rate is your total tax paid divided by your taxable income (your average rate). Because of the progressive nature of the tax code, your effective rate is always lower than your marginal bracket.
3. How Graduated Brackets are Calculated
Entering a higher tax bracket does not increase the tax rate on your entire income. Only the income above the bracket threshold is taxed at the higher rate. For example, if you enter the 22% bracket, your lower earnings are still taxed at 10% and 12%, protecting your take-home pay.
4. Shifting Brackets with Deductions
You can lower your tax bracket by reducing your taxable income. Contributing to pre-tax retirement plans (traditional 401k or IRA) and funding Health Savings Accounts (HSAs) lowers your Adjusted Gross Income, which can push you into a lower marginal tax bracket.
