State income tax varies dramatically across the United States. Nine states have no income tax at all, while others impose progressive tax rates that can exceed 13% on high earners. Understanding your state's tax burden is crucial for financial planning, relocation decisions, and retirement strategies. This calculator helps you compare your effective tax rate across all 50 states and Washington DC, showing you exactly how much you'd owe in income tax in each jurisdiction. Use it to evaluate where you'll keep more of your paycheck, whether you're considering relocating or simply curious about your current tax situation.
Nine states have no state income tax: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. New Hampshire is unique—it taxes interest and dividend income but not wages. These states typically compensate for lost income tax revenue through higher sales taxes, property taxes, or other fees. If you work remotely and have flexibility in where you live, these states can provide significant tax savings, especially for high earners.
Your marginal tax rate is the rate you pay on your last dollar of income, while your effective tax rate is your total tax divided by your total income. In progressive tax systems, you pay lower rates on lower income brackets and higher rates on higher brackets. For example, you might be in the 6% marginal bracket but have an effective rate of only 3.5%. This calculator shows your effective rate, which is the true percentage of your income going to state taxes.
Yes. Most states allow a standard deduction similar to federal taxes. This deduction reduces your taxable income before the state tax rate is applied. Some states allow you to claim the federal deduction, while others have their own deduction amounts. Higher deductions mean lower taxable income and less tax owed. A few states don't allow any deduction or have very minimal amounts. This calculator includes state-specific deductions in all calculations.
Most states follow federal filing status categories (Single, Married Filing Jointly, etc.), but some apply different tax rates or deductions by status. Married couples filing jointly often get lower effective rates due to graduated brackets, though rates vary significantly by state. Some states also recognize common-law marriages differently. This calculator applies the correct deductions and brackets for your selected filing status in each state.
Absolutely. For high earners, state income tax differences can mean thousands of dollars annually. However, relocation decisions should consider the full tax picture: state income tax, sales tax, property tax, and cost of living. A state with no income tax might have high property taxes. Use this calculator to quantify the income tax impact, then research other taxes and living costs in your target state. Over a lifetime, these differences compound significantly.
This calculator uses 2025 tax rates and brackets for all 50 states and DC. For flat-tax states, the calculation is simple: (Income - Deduction) × Rate. For progressive states with multiple brackets, we apply each bracket rate to the appropriate portion of your taxable income (Taxable Income = Income - State Deduction). Brackets and deductions are specific to your filing status. Calculations do not include federal tax, local taxes, credits, or alternative minimum taxes—this focuses purely on state income tax liability.
