Income Tax Estimator
Estimate US federal income tax and take-home pay.
📊 Simplified US 2024 federal brackets. Excludes state tax, deductions, and credits. Estimate only.
What Is This Tool?
This estimator calculates your US federal income tax using 2024 tax brackets. It applies the standard deduction automatically and shows your estimated tax, effective rate, and take-home pay. This is an estimate only — your actual tax depends on deductions, credits, and state taxes.
How Progressive Tax Brackets Work
Many people think moving into a higher bracket means all their income is taxed at the higher rate. That's a myth. Only the income above each bracket threshold is taxed at that rate. Your marginal rate is the rate on your last dollar earned; your effective rate is your total tax divided by total income.
What's Included and Excluded
- Included: Federal income tax using 2024 brackets
- NOT included: State tax (0-13% depending on state), FICA (Social Security + Medicare = 7.65%), local taxes
- Standard deduction: $14,600 single / $29,200 married (2024)
- Not considered: 401(k) contributions, child credits, education credits, itemized deductions
Marginal vs. Effective Rate
A single person earning $75,000 has a marginal rate of 22% (their top bracket), but their effective rateis only about 13% because most of their income is taxed at lower rates. Always know your effective rate — that's what you actually pay.
Frequently Asked Questions
Why does my paycheck show more tax withheld?
Employers withhold based on your expected annual tax plus a margin of safety. Withholdings are estimates; your actual tax is settled when you file. You get a refund if you overpaid.
