How US Income Tax Brackets Work
The US uses a progressive tax system, meaning different portions of your income are taxed at different rates. A common misconception is that moving into a higher bracket means all your income is taxed at that rate — in reality, only the income within each bracket is taxed at that bracket's rate. This calculator breaks down your liability bracket-by-bracket so you can see exactly where your money goes.
The standard deduction reduces your taxable income before brackets are applied. For 2024, it's $14,600 for single filers. If your itemized deductions exceed the standard amount, enter that figure instead for a more accurate estimate. This tool is for educational purposes — consult a tax professional for filing advice.
