About This Income Tax Calculator
This calculator estimates your federal income tax liability using the 2024 IRS tax brackets and standard deduction. The US uses a progressive tax system, where different portions of your income are taxed at different rates.
How Federal Income Tax Works
- Gross Income: Your total annual income before any deductions
- Standard Deduction: A fixed amount subtracted from gross income based on filing status
- Taxable Income: Gross income minus the standard deduction
- Tax Brackets: Taxable income is divided into brackets, each taxed at its rate
- Total Tax: Sum of tax from all brackets
2024 Standard Deductions
- Single: $14,600
- Married Filing Jointly: $29,200
- Married Filing Separately: $14,600
- Head of Household: $21,900
Understanding Marginal vs Effective Tax Rate
Your marginal tax rate is the rate on your last dollar of income (your highest bracket). Your effective tax rate is the percentage of your total income you actually pay in taxes. Because of progressive brackets, your effective rate is always lower than your marginal rate.
For example, if you're in the 22% bracket, only the income within that bracket is taxed at 22%. Income in lower brackets is still taxed at those lower rates.

Income Tax Calculator FAQ
How do I calculate my federal income tax?
To calculate federal income tax, subtract the standard deduction from your gross income to get taxable income. Then apply the progressive tax brackets for your filing status. Each bracket taxes income within that range at the bracket's rate.
What is an effective tax rate?
Your effective tax rate is the percentage of your total income that you actually pay in taxes. It's calculated by dividing total tax owed by gross income. It's usually lower than your marginal (top) tax rate because of progressive brackets.
What is the standard deduction for 2024?
For 2024, the standard deduction is $14,600 for single filers, $29,200 for married filing jointly, and $21,900 for head of household.
