State Income Tax Calculator

State income tax across the three structures states actually use. Nine states levy none, several use a single flat rate, and the rest are progressive with brackets that differ enormously.

Also called: state tax calculator, state income tax by bracket.

$6,200.00

$6,200.00 of state income tax on 120,000, an effective rate of 5.17% and a marginal rate of 8%. Progressive brackets tax only the income inside each band, so a higher bracket never reduces take-home pay.

How this is calculated

Computed from the published rates for the tax year you selected, which is not necessarily the current year. A calculation, not tax advice, and it does not know anything about your circumstances beyond the figures entered.

Method and background

This is what the calculation gives for the numbers you entered. It is an estimate, not advice, and it knows nothing about your situation beyond those numbers. Rules for United States change on a published schedule; the effective date is shown on every rule-based tool.

How this is calculated

A progressive state applies each rate only to the income inside that bracket, exactly as federal brackets work: reaching a higher bracket never reduces take-home pay. Flat-rate states apply one rate to everything above the state deduction. Nine states levy no income tax at all, which is often offset by higher property or sales taxes rather than being straightforwardly cheaper.

each bracket taxes only the income falling inside it

Method and limits

What it assumes

  • A single set of brackets. Real state schedules vary by filing status.

What it deliberately does not model

  • State rules for deductions, exemptions and credits differ substantially and are simplified here.
  • Local income taxes in some cities are separate and not included.
  • This is an estimate, not a state return.

Frequently asked questions

Is a no-income-tax state cheaper overall?
Not necessarily. States without an income tax generally raise more through property and sales taxes, so the total burden depends on your spending and housing rather than only your income.
