What this result means

At a 5% top marginal rate on $75,000 gross, estimated state income tax is $3750 (5.0% effective rate). This is a simplified estimate — actual tax depends on your state's bracket structure and deductions.

How this is calculated

taxableIncome = grossIncome − deductions
stateTax = taxableIncome × stateRate
effectiveRate = stateTax / grossIncome

State Income Tax in the US (2025)

41 states levy a personal income tax. The remaining 9 — Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming — have no state income tax on wages.

How this calculator works

This calculator uses your state's top marginal rate as a simplified estimate. Most states use progressive brackets, so your actual average rate will be lower — especially at middle-income levels. Think of this as the upper-bound estimate.

For accurate withholding, use your employer's W-4 and your state's equivalent withholding form.

State tax is in addition to federal

Federal income tax (10–37% brackets) applies to everyone regardless of state. Your total marginal burden is federal + state combined. High earners in California face a combined federal + state top rate exceeding 50%.

Assumptions

Uses the state's top statutory marginal rate as a simplified estimate. Actual tax liability depends on your state's bracket structure — most states tax lower income at lower rates.
No state-specific deductions, exemptions, or credits are modeled (standard deductions, personal exemptions, child credits vary significantly by state).
Flat-rate states: this calculator accurately reflects the rate for income above any threshold. Progressive states: this overstates tax for most income levels.
Massachusetts 9% rate includes the 4% millionaires surtax on income above $1,000,000. The base rate for most filers is 5%.
New Jersey 10.75% applies to income over $1,000,000. Most NJ filers pay 6.37% (up to $500K).
New York 10.9% applies to income over $25,000,000. Most NY filers pay 6.85% (up to $215,400).

Frequently asked questions

›Which states have no income tax in 2025?

Nine states have no wage income tax: Alaska, Florida, Nevada, New Hampshire (eliminated its interest/dividends tax effective January 2025), South Dakota, Tennessee, Texas, Washington, and Wyoming. Washington has a 7% capital gains tax on gains above $262,000, but no general income tax.

›Is the top marginal rate what I actually pay?

No — the top marginal rate applies only to income above the top bracket threshold. Most states use progressive brackets where lower income is taxed at lower rates. Your effective rate (total tax ÷ total income) will be meaningfully lower than the top marginal rate, especially if you're in a middle-income bracket.

›Does state income tax reduce my federal taxable income?

Yes, if you itemize federal deductions. State and local taxes (SALT) are deductible on federal Schedule A, up to a combined cap of $10,000 (the SALT deduction cap, currently in effect through 2025 under current law). If you take the standard federal deduction, you do not get an additional SALT deduction.

›What about local income taxes?

Several states allow cities and counties to levy their own income tax. New York City adds up to 3.876% on top of the state rate. Philadelphia charges 3.75%. Detroit, Kansas City, and Columbus also have local taxes. This calculator shows state-level rates only — check your city/county for additional local taxes.

›How do flat-rate states differ from bracket states?

Flat-rate states (Illinois at 4.95%, Pennsylvania at 3.07%, Colorado at 4.4%) apply one rate to all taxable income above any exemptions. Bracket states apply different rates to different income tiers — the top marginal rate only applies to income above the top threshold, while lower income is taxed at lower rates.
