Understanding Your Tax Rates:

Your Marginal Tax Rate is the rate of tax applied to the *last* dollar of your taxable income. It is determined by the highest tax bracket your taxable income falls into.

Your Effective Tax Rate (also known as the Average Tax Rate) is calculated by dividing your total tax liability by your Adjusted Gross Income (AGI). This rate represents the overall percentage of your AGI paid in federal income tax.

Note on Calculations: This calculator estimates federal income tax liability based on taxable income (AGI minus the greater of the Standard or Itemized Deductions taken) and the statutory tax brackets for the selected year and filing status. It provides estimates for Tax Years 2024 and 2025. It does not account for all possible tax situations, credits, deductions, state taxes, or other factors that may affect your final tax liability. Tax laws are subject to change. Consult official IRS publications or a qualified tax professional for personalized tax advice.
