🧾 What is a State Tax Calculator?

A state tax calculator estimates how much state income tax you owe based on your gross annual income, filing status, and the specific tax rules of your state. The United States has no single unified income tax rate at the state level. Instead, each state sets its own rules: nine states impose no income tax at all, sixteen states use a flat rate, and the remaining twenty-six states plus Washington DC use progressive bracket systems where higher portions of income are taxed at higher rates.

This calculator is useful in several key situations: comparing job offers in different states and understanding the after-tax difference; planning a relocation and estimating your new tax burden; modeling salary negotiations; and understanding how much of a raise will actually reach your pocket after state taxes. For a household considering a move from California to Texas on the same $120,000 salary, the state tax savings alone can exceed $8,000 per year.

A common misconception is that moving to a "lower bracket" means all your income is taxed at the lower rate. In progressive states, only the income above each bracket threshold is taxed at the higher rate. Your effective rate is always lower than your marginal rate. A Minnesota single filer earning $75,000 has a 6.8% marginal rate but pays an effective rate closer to 5.4% because most of their income falls in the lower 5.35% bracket.

This calculator covers all 50 states and Washington DC with 2025 tax year data. Results are estimates based on gross income. Most states offer standard deductions, personal exemptions, and credits that reduce taxable income further, which means your actual tax bill may be somewhat lower than the figure shown. Use this calculator for planning and comparison purposes, and confirm precise figures with your state's official tax tables or a licensed tax professional.

📐 Formula

State Tax  =  Σ ri × (min(I, Bi) − Bi-1)
I = taxable income (gross income in this calculator)
ri = tax rate for bracket i
Bi = upper threshold of bracket i (Infinity for the top bracket)
Bi-1 = lower threshold of bracket i (0 for the first bracket)
Effective Rate = Total State Tax ÷ Gross Income × 100
Example: Virginia single, $75,000 income: 2% on $3,000 = $60; 3% on $2,000 = $60; 5% on $12,000 = $600; 5.75% on $58,000 = $3,335. Total = $4,055. Effective rate = 4,055 / 75,000 = 5.41%

📖 How to Use This Calculator

Steps

1
Select your state - Choose any of the 50 US states or Washington DC from the dropdown. States with no income tax on wages are labeled clearly. The calculator pre-loads with California selected as a starting point.
2
Set your filing status - Click Single, Married (MFJ), or Head of Household. For flat-rate states this makes no difference. For progressive states, Married typically uses wider bracket thresholds, reducing the tax on combined income.
3
Enter your annual gross income - Type your salary or drag the slider. Use the same number you earn before any deductions. To compare states fairly, keep this number constant while switching states.
4
Review your state tax breakdown - Click Calculate to see your estimated state income tax, effective and marginal rates, monthly tax equivalent, and annual take-home pay after state tax. Change the state in the dropdown to instantly compare two states side by side by running the calculation twice.

💡 Example Calculations

Example 1 - California Single Filer, $75,000

California 2025 progressive brackets, Single filing, $75,000 gross income

1
1% on first $10,756 = $107.56
2
2% on $10,756 to $25,499 = $294.86
3
4% on $25,499 to $40,245 = $589.84
4
6% on $40,245 to $55,866 = $937.26
5
8% on $55,866 to $70,606 = $1,179.20. Then 9.3% on $70,606 to $75,000 = $408.67
California state tax = $107 + $295 + $590 + $937 + $1,179 + $409 = $3,517 | Effective rate: 4.69%

Example 2 - Texas, $75,000 (No State Tax)

Texas has no state income tax on wages. Same $75,000 income, $0 state tax.

1
Texas imposes no personal income tax on wages or salaries. The Texas Constitution prohibits it.
2
A $75,000 earner who moves from California to Texas saves approximately $3,517 per year in state income tax alone.
3
Texas funds state government primarily through sales tax (6.25% state + up to 2% local = up to 8.25%) and property taxes, which average around 1.7% of home value annually.
Texas state income tax on $75,000 = $0 | Annual take-home advantage vs California: +$3,517

❓ Frequently Asked Questions

Which US states have no income tax in 2025?+
Nine states have no income tax on wages: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. New Hampshire phased out its tax on interest and dividends in 2025, making it fully income-tax-free. Washington has a 7% capital gains tax on long-term gains above $270,000 but taxes no wages. These states fund government through sales taxes, property taxes, severance taxes, and other revenue sources.
What is the highest state income tax rate in the US?+
California has the highest top marginal state income tax rate at 13.3% on taxable income over $1 million for single filers. Hawaii is second at 11% on income over $300,000. New Jersey reaches 10.75% above $1 million. District of Columbia tops out at 10.75% above $1 million. Oregon reaches 9.9% above $125,000, making it the highest practical rate for upper-middle-income earners.
How much state tax do I pay on a $100,000 salary?+
On $100,000 single filing, approximate 2025 state taxes include: California $6,601, New York $6,073, New Jersey $5,525, Oregon $7,463, Minnesota $6,418, Illinois $4,950 (flat), Pennsylvania $3,070 (flat), North Carolina $4,500 (flat), Colorado $4,400 (flat), Texas $0, Florida $0. The spread from $0 to $7,463 shows how dramatically state choice affects take-home pay.
What is the difference between flat and progressive state income tax?+
A flat-rate state applies one percentage to all taxable income regardless of amount. Illinois at 4.95% taxes $30,000 and $300,000 at the same rate. A progressive state applies increasing rates to higher portions of income. California's first $10,756 is taxed at 1%, then the next tier at 2%, and so on up to 13.3%. Progressive systems collect proportionally more from high earners. Flat systems are simpler to compute and more predictable.
Can I deduct state income taxes on my federal return?+
Yes, if you itemize deductions on your federal return. However, the SALT deduction cap limits the combined deduction for state income tax (or sales tax) plus property taxes to $10,000 per year ($5,000 for married filing separately). This cap, introduced by the Tax Cuts and Jobs Act of 2017, significantly reduces the federal tax benefit for residents of high-tax states like California, New York, New Jersey, and Illinois.
Is the state tax calculator accurate for my actual tax return?+
This calculator provides a close estimate for planning purposes. Your actual state tax liability may differ because: (1) most states have their own standard deductions or exemptions applied before computing tax; (2) you may have deductions for retirement contributions, business expenses, or other adjustments; (3) states offer various credits (child tax credit, earned income credit, education credits) that reduce final tax owed; and (4) investment income, self-employment income, and other income types may be taxed differently. Use it for comparison and budgeting, not for filing.
How does filing status affect state income tax?+
In progressive states, Married Filing Jointly typically uses wider bracket thresholds that reduce the marginal rate on combined household income. For example, Minnesota's 5.35% bracket covers income up to $32,080 single but up to $46,890 for married filers. Flat-rate states apply the same percentage regardless of filing status. Head of Household status generally falls between single and married thresholds and benefits single parents with dependents.
What states have recently lowered their income tax rates?+
Major rate cuts since 2022 include: Arizona moved to a 2.5% flat rate in 2023 from a previous top rate of 4.5%; Iowa adopted a 3.8% flat rate in 2025, down from 8.53% progressive brackets; Louisiana moved to a 3% flat rate in 2025 from rates as high as 6%; Montana moved to a 5.9% flat rate in 2024; North Dakota simplified to 1.1% in 2024; Georgia reduced its flat rate to 5.49% in 2024 with further reductions planned. This trend reflects competition to attract businesses and high-income residents.
Does moving to a lower-tax state really save money after all costs?+
The net savings depend on your full financial picture. Moving from California to Texas on a $150,000 salary saves roughly $10,000 per year in state income tax. However, Texas has higher property taxes (averaging 1.7% vs California's Prop 13-limited rates often below 1%), and if you sell a California home you may owe California exit taxes on accrued gains. For renters or new homebuyers, the state tax savings are usually clear. Factor in cost of living, housing costs, healthcare access, and career opportunities for a complete picture.
What is the state income tax in Washington DC?+
Washington DC (the District of Columbia) has a progressive income tax with seven brackets ranging from 4% on income up to $10,000 to 10.75% on income over $1 million for 2025. On $75,000 single, DC tax is approximately $4,175 (effective rate 5.57%). On $200,000 single, DC tax is approximately $14,075 (effective rate 7.04%). DC residents pay no state taxes to Maryland or Virginia but do pay a "DC state" tax to the local government.
How do I calculate my marginal vs effective state tax rate?+
Your marginal rate is simply the top bracket rate your income falls into. Your effective rate is total state tax divided by total gross income, expressed as a percentage. For a California single filer earning $75,000: marginal rate is 9.3% (the bracket covering $70,606 to $360,659); effective rate is approximately 4.7% ($3,517 / $75,000). The effective rate is the figure that matters for comparing your real tax burden across states.

Which states have no income tax in 2025?

Nine states impose no income tax on wages: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. Note that Washington has a 7% capital gains tax on gains above $270,000. New Hampshire phased out its interest and dividends tax as of 2025. Living in a no-tax state saves a household earning $100,000 roughly $3,000 to $6,000 per year compared to an average-tax state.

What is the difference between effective and marginal state tax rate?

Your marginal state tax rate is the rate applied to your last dollar of income - the top bracket rate you fall into. Your effective rate is total state tax divided by total income. Because progressive brackets only apply higher rates to income above each threshold, your effective rate is always lower than your marginal rate. For example, a California single filer earning $75,000 has a marginal rate of 9.3% but an effective rate of about 4.9%.

How does this state tax calculator work?

Select your state, enter your annual gross income, and choose your filing status. The calculator applies your state's 2025 tax brackets to your income and computes the total state income tax, effective rate, marginal rate, and monthly equivalent. For flat-rate states it applies the single rate directly. For states with no income tax it returns zero.

Which state has the highest income tax rate in 2025?

California has the highest marginal state income tax rate at 13.3% on income over $1,000,000 for single filers. Hawaii follows at 11% on income over $300,000. New Jersey tops out at 10.75% on income over $1,000,000. For most middle-income earners, Oregon (9.9%) and Minnesota (9.85%) represent the highest practical top rates on income above $125,000 and $174,321 respectively.

What is the lowest state income tax rate in the US?

Among states with an income tax, North Dakota has the lowest flat rate at 1.1% for 2025. Pennsylvania has a flat 3.07%. Indiana is at 3.05%. Louisiana moved to a flat 3.0% starting in 2025. Arizona is at 2.5% flat, making it the lowest rate among all states that do have an income tax. Tennessee and New Hampshire effectively have 0% on earned wages as of 2025.

Are state income taxes deductible on federal taxes?

State income taxes paid are deductible on your federal return if you itemize deductions, subject to the SALT cap. The Tax Cuts and Jobs Act of 2017 capped the deduction for state and local taxes (state income or sales tax plus property taxes) at $10,000 per year ($5,000 married filing separately). This cap disproportionately affects residents of high-tax states like California, New York, and New Jersey.

How much state tax will I pay on a $75,000 salary?

At $75,000 gross income filing single, approximate 2025 state taxes range from $0 in no-tax states to about $5,735 in California (effective rate 7.6%), $4,363 in New York (5.8%), $3,375 in Illinois (4.95% flat), $2,303 in Pennsylvania (3.07% flat), and $0 in Texas or Florida. Most states fall in the $2,000 to $4,000 range for this income level.

Does filing status affect state income tax?

Yes for most progressive states. Married Filing Jointly typically has wider bracket thresholds (often double the single thresholds), which can significantly reduce the tax on combined household income. Some states, like California and New York, have nearly identical brackets for single and MFJ filers. Flat-rate states like Illinois and Pennsylvania apply the same rate regardless of filing status, so filing status has no effect there.

Why does my actual state tax bill differ from this calculator?

This calculator applies state tax brackets to your gross income. In practice, states also allow standard deductions, personal exemptions, retirement income exclusions, and other credits that reduce your taxable income. For example, California has a standard deduction of $5,202 for single filers, which would reduce the estimated tax shown. For precise figures, consult your state's official tax tables or a tax professional.

What states have recently cut income tax rates?

Several states enacted major income tax cuts between 2022 and 2025: Arizona moved to a 2.5% flat rate in 2023, Iowa to 3.8% flat in 2025, Louisiana to 3% flat in 2025, Montana to 5.9% flat in 2024, and North Dakota simplified to 1.1% flat in 2024. Georgia reduced its flat rate to 5.49% in 2024 and continues reducing it toward 4.99%. These cuts reflect a broad trend of states competing for mobile, high-income residents.

How do I calculate state income tax manually?

For flat-rate states: multiply your gross income by the flat rate. For progressive-bracket states: divide your income across the brackets, multiply each portion by that bracket rate, and sum the results. For example, Virginia single: 2% on first $3,000 = $60; 3% on next $2,000 = $60; 5% on next $12,000 = $600; 5.75% on remaining income above $17,000. On $75,000: $60 + $60 + $600 + (75,000 - 17,000) x 0.0575 = $60 + $60 + $600 + $3,335 = $4,055.

📌 Quick Tips

💡Nine states have no income tax on wages: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. Living in one of these can save a high earner $5,000 to $20,000 per year vs. a high-tax state.
💡Your effective state tax rate is always lower than your marginal rate because only the income above each bracket threshold is taxed at the higher rate. An effective rate of 4% in California means your average rate across all brackets is 4%, not that all your income is taxed at 4%.
💡This calculator estimates tax on your gross income. In practice, most states apply their own standard deductions or exemptions before computing tax, so your actual state tax bill may be slightly lower than the estimate shown.
💡High-income earners in California, New York, Oregon, Minnesota, and New Jersey pay the most in state income tax. At $500,000 of income, the California rate alone adds over $50,000 in state taxes.
💡Several states have recently enacted major rate cuts: Iowa moved to a flat 3.8% in 2025, Louisiana to a flat 3%, Montana to a flat 5.9%, and North Dakota dropped to 1.1%. Check the latest rates with your state revenue department each year.
