How the Income Taxes Calculator Works
The income taxes calculator computes your estimated tax liability based on your gross income, filing status, and state of residence. Here's how it works:

- Click "Calculate" to see your estimated taxes
The calculator provides a breakdown of federal income tax, state income tax (if applicable), and FICA taxes (Social Security and Medicare).
Note: This calculator provides an estimate. Your actual tax liability may vary based on deductions, credits, and other factors not accounted for in this calculation.
Federal Income Taxes Explained
Federal income tax is the primary tax imposed by the US government on individuals. The tax is progressive, meaning higher income brackets are taxed at higher rates.
The federal income tax system includes several types of taxes:
- Income tax on wages, salaries, and other forms of income
- Alternative minimum tax (AMT) for high-income earners
- Self-employment tax for those who are self-employed
Federal income tax rates range from 10% to 37% depending on your income level and filing status.
State Income Taxes Overview
In addition to federal taxes, most states impose their own income taxes. The rates and rules vary significantly by state.
Some states have no income tax, while others have rates ranging from 1% to over 13%.
State income taxes are typically calculated on a similar progressive system to federal taxes, but with different brackets and rates.
Note: Some states may have additional taxes such as sales tax, property tax, or other levies that are not included in this calculator.
FICA Taxes (Social Security & Medicare)
FICA (Federal Insurance Contributions Act) taxes are payroll taxes that fund Social Security and Medicare programs.
There are two main FICA taxes:
- Social Security tax (6.2%)
- Medicare tax (1.45%)
For 2024, the combined FICA tax rate is 7.65%.
FICA taxes are withheld from employee wages and paid by employers, but the employee portion is deducted from your paycheck.
