Calculate your estimated USA income tax by state with our free tax calculator. This tool provides federal and state tax estimates based on your income and filing status. While it's not a substitute for professional tax advice, it helps you understand your potential tax liability.
How the USA Income Tax Calculator Works
The USA income tax system is progressive, meaning higher income brackets are taxed at higher rates. The calculator combines federal tax rates with your state's rates to provide a comprehensive estimate. Here's how it works:
This calculator uses 2024 tax rates and assumes standard deductions. Rates and brackets may change annually. For exact tax liability, consult a tax professional.
Federal Tax Calculation
The federal government taxes income in brackets. For example, if you earn $50,000:
- $11,000 at 10%
- $33,000 at 12%
- $5,000 at 22%
State Tax Calculation
Each state has its own tax rates and brackets. Some states tax only the amount over a certain threshold, while others tax the full amount. The calculator applies the appropriate method for your selected state.
Combined Tax Estimate
The calculator adds federal and state taxes to provide your total estimated tax liability. It also shows your effective tax rate (total tax divided by income).
Federal Income Tax Rates
Federal income tax rates for 2024 are:
| Taxable Income | Tax Rate |
|---|---|
| $0 - $11,000 | 10% |
| $11,001 - $44,725 | 12% |
| $44,726 - $95,375 | 22% |
| $95,376 - $182,100 | 24% |
| $182,101 - $231,250 | 32% |
| $231,251 - $578,125 | 35% |
| $578,126+ | 37% |
These rates apply to single filers. Married couples filing jointly have different brackets.
State Income Tax Rates
State income tax rates vary significantly. Some states have no income tax, while others have rates up to 9.9%. Here are some examples:
| State | Tax Rate | Notes |
|---|---|---|
| California | 1-13.3% | Progressive rates |
| New York | 4-10.9% | Progressive rates |
| Texas | 0% | No income tax |
| Washington | 0% | No income tax |
| Nevada | 0% | No income tax |
For exact rates and brackets, select your state in the calculator.
