- Select your filing status — choose Single or Married Filing Jointly. The brackets and standard deduction differ for each status.
- Review results — see your total federal tax, after-tax income, effective tax rate and marginal tax rate. The table below shows the exact tax calculation for each bracket.
The calculator uses the 2024 US federal income tax brackets and applies the standard deduction automatically. It does not include state taxes, FICA or other deductions.
Frequently Asked Questions
What is the difference between effective and marginal tax rate?
Your marginal tax rate is the rate applied to your last dollar of taxable income — the highest bracket you fall into. Your effective tax rate is the overall percentage of your total income that goes to federal tax. The effective rate is always lower than the marginal rate because income is taxed progressively.
What are the 2024 federal tax brackets?
For single filers: 10% ($0–$11,600), 12% ($11,601–$47,150), 22% ($47,151–$100,525), 24% ($100,526–$191,950), 32% ($191,951–$243,725), 35% ($243,726–$609,350), 37% (over $609,350). Married filing jointly brackets are roughly double.
What is the standard deduction for 2024?
The 2024 standard deduction is $14,600 for single filers and $29,200 for married filing jointly. This amount is subtracted from your gross income to determine your taxable income.
Does this include state income tax?
No. This calculator only computes federal income tax. State income taxes vary widely — some states have no income tax while others have rates up to 13.3%. Add your state tax separately for a complete picture.
Does this include Social Security and Medicare taxes?
No. FICA taxes (6.2% for Social Security + 1.45% for Medicare) are separate from income tax and are not included here. Use our Paycheck Calculator for a complete take-home pay estimate.
