Frequently Asked Questions
How do US federal tax brackets work?
The US uses a progressive tax system with seven tax brackets. You pay the rate for each bracket only on income within that bracket's range, not your entire income.
What's the difference between marginal and effective tax rates?
Your marginal tax rate is the rate you pay on your last dollar of income. Your effective tax rate is your total tax divided by your total income.
Does this include state taxes?
No, this calculator only includes federal income tax. State income tax rates vary by state, with some states having no income tax.
When are taxes due for 2024?
Federal income tax returns for 2024 are typically due on April 15, 2025, unless that date falls on a weekend or holiday.
About the US Federal Tax System
The United States federal income tax system is a progressive tax system administered by the Internal Revenue Service (IRS). This means that tax rates increase as taxable income increases, with seven tax brackets ranging from 10% to 37% for the 2024 tax year.
Our US tax calculator uses the official IRS tax brackets for 2024 and includes the standard deduction amounts. The calculator supports all filing statuses: Single, Married Filing Jointly, Married Filing Separately, and Head of Household.
Important Note: This calculator estimates federal income tax only. Your total tax liability may include state income tax, Social Security tax (6.2% on wages up to $160,200 in 2024), Medicare tax (1.45% on all wages), and additional Medicare tax (0.9% on wages over $200,000 for single filers).
