Estimate your US federal income tax for 2024
Estimate your 2024 US federal income tax liability quickly with our free income tax calculator. Simply enter your annual income and select your filing status — Single or Married Filing Jointly — to compute your total tax across progressive brackets.
Understanding your income tax liability is essential for effective financial planning. Our calculator uses the latest 2024 tax brackets and standard deduction amounts to provide you with a quick and accurate estimate of what you can expect to owe the IRS. Whether you're planning your withholdings, estimating quarterly payments, or simply curious about your tax situation, this tool gives you clarity in seconds.
The calculator breaks down your tax by bracket, showing exactly how much income falls into each rate tier. This transparency helps you understand the progressive nature of the US tax system and how additional income would be taxed at your marginal rate.
Your taxable income is your total income minus the standard deduction. Tax is then computed using progressive brackets: income in each bracket is taxed at that bracket's rate, and the results are summed.
Your marginal tax rate is the rate applied to your last dollar of income, while your effective tax rate is your total tax divided by your total income — a blended average of all the brackets you fall into.
No, this calculator uses the standard deduction only. Itemized deductions, credits, and other adjustments are not included for simplicity.
Contributions to tax-deferred retirement accounts like a 401(k) or traditional IRA, Health Savings Account (HSA) contributions, and above-the-line deductions can lower your adjusted gross income and reduce your tax liability.
For 2024, the standard deduction is $14,600 for single filers and $29,200 for married couples filing jointly. This amount is subtracted from your income before tax is computed.
This calculator estimates federal income tax only and does not include self-employment tax. Self-employed individuals should also account for Social Security and Medicare taxes separately.
