How to Use This Tax Calculator
Enter your annual gross income, select your filing status, and input your state's income tax rate. The calculator will estimate your federal and state taxes using 2024 tax brackets. If you have significant itemized deductions (mortgage interest, charitable donations, etc.), enter them; otherwise, the standard deduction will be used.
Understanding Tax Brackets
The U.S. uses a progressive tax system, meaning different portions of your income are taxed at different rates. Your marginal rate is the highest bracket your income reaches, while your effective rate is the actual percentage of your total income paid in taxes. The effective rate is always lower than your marginal rate.
Standard vs. Itemized Deductions
Most taxpayers benefit from taking the standard deduction, which for 2024 is $14,600 for single filers, $29,200 for married filing jointly, and $21,900 for head of household. Only itemize if your deductible expenses exceed these amounts.
State Income Taxes
State income tax rates vary significantly. Nine states have no income tax: Alaska, Florida, Nevada, New Hampshire (dividends only), South Dakota, Tennessee, Texas, Washington, and Wyoming. Others range from about 1% to over 13% (California's top bracket). Enter your state's rate for a more accurate estimate.
