Use this income tax calculator to estimate your 2024 federal and state income tax liability in the United States. The calculator uses the 2024 tax brackets and standard deductions to provide an estimate of your tax obligation.
How the 2024 US Income Tax Calculator Works
The 2024 US income tax calculator estimates your federal and state income tax liability based on your total income and filing status. Here's how it works:
- Enter your total taxable income for the year.
- Select your filing status (Single, Married Filing Jointly, etc.).
- Choose your state of residence.
- Click "Calculate" to see your estimated tax liability.
Federal Income Tax Formula
The calculator applies the progressive federal tax brackets to your income. For example, if you earn $50,000 as a single filer:
- $11,600 is taxed at 10%
- $36,400 is taxed at 12%
- $900 is taxed at 22%
Total federal tax = $1,160 + $4,368 + $198 = $5,726
The calculator provides an estimate only. Your actual tax liability may differ based on your specific circumstances, deductions, and credits.
