How Our State Tax Calculator Works
Our calculator computes the state income tax for all 50 states simultaneously, using the actual 2026 tax brackets, rates, and standard deductions for each state. Here is what it accounts for:
- Flat tax states (14 states) — A single rate applied to all taxable income. Examples: Illinois (4.95%), Pennsylvania (3.07%), Arizona (2.50%)
- Graduated tax states (29 states + DC) — Multiple brackets where higher income is taxed at progressively higher rates. Examples: California (1%-13.3%), New York (4%-10.9%)
- No income tax states (7 states + NH) — Alaska, Florida, Nevada, South Dakota, Texas, Washington, Wyoming
- Standard deductions — Each state's standard deduction is applied where applicable
- Filing status — Brackets and deductions adjust for single vs. married filing jointly
- This calculator estimates state income tax only. It does not include federal income tax, FICA/Social Security, property tax, or sales tax
- Actual tax liability may differ based on itemized deductions, credits, and state-specific adjustments
- For self-employment income, use our self-employment tax calculator
- To compare two specific states in detail, use our state comparison tool
Understanding State Tax Types
No Income Tax States
Seven states impose no income tax at all: Alaska, Florida, Nevada, South Dakota, Texas, Washington, and Wyoming. New Hampshire eliminated its interest and dividends tax in 2025, effectively joining this group. Living in these states means 100% of your income avoids state income tax, though other taxes (property, sales) may be higher to compensate.
Flat Tax States
Fourteen states use a flat (single-rate) income tax. Every dollar of taxable income is taxed at the same rate, making these the simplest to calculate. The lowest flat rate is Arizona at 2.50%, and the highest is Massachusetts at 5.00% (plus a 4% surcharge on income over $1M).
Graduated (Progressive) Tax States
The remaining 29 states plus DC use graduated brackets. Your income is taxed in layers: the first portion at the lowest rate, the next portion at a higher rate, and so on. Only the income within each bracket is taxed at that bracket's rate. This means your effective (average) tax rate is always lower than your marginal (top) rate.
For example, in California with $200,000 of taxable income, you do not pay 9.3% on the entire amount. Instead, you pay 1% on the first $10,412, 2% on the next $14,282, and so on up through the brackets. The result is an effective rate well below the 9.3% marginal rate.

Tips for Minimizing Your State Tax
- Understand your residency status — You typically owe tax to the state where you are domiciled. If you split time between states, understand the rules for establishing residency
- Maximize state deductions — Many states offer deductions beyond the standard deduction, including 529 plan contributions, HSA contributions, and charitable donations
- Consider timing — If relocating to a lower-tax state, time income recognition (bonuses, stock sales) to occur after establishing residency
- Use the SALT deduction wisely — If you itemize on your federal return, state income taxes (up to $10,000 combined with property taxes) are deductible
- Look at the total picture — A state with no income tax may have higher property or sales taxes that offset the savings. Use our cheapest states guide for the full analysis
Frequently Asked Questions
State income tax is calculated on your taxable income after deductions and exemptions. Most states start with your federal adjusted gross income (AGI) and apply their own rates. Use our calculator above to see your exact tax in all 50 states.
It depends on your income level. At lower incomes, graduated-tax states can be cheaper than flat-tax states. At higher incomes, no-income-tax states always win. Our calculator shows your exact tax in every state so you can compare directly.
You generally owe income tax to your state of residence. If you work in a different state, you may also owe tax there, but most states offer credits to prevent double taxation. Some neighbouring states have reciprocity agreements.
Yes, state and local taxes (SALT) are deductible if you itemize, but capped at $10,000 per return. This cap was introduced by the Tax Cuts and Jobs Act of 2017.
