State Income Tax Calculator

State income tax rates vary dramatically across the United States. Nine states charge no income tax at all: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. At the other extreme, California leads with a top rate of 13.3%, followed by Hawaii at 11% and New Jersey at 10.75%.

States use three main approaches to income taxation. Progressive tax systems have multiple brackets where higher income is taxed at higher rates. Flat tax states charge a single rate on all income. No income tax states fund government through other means like sales taxes, property taxes, or natural resource revenues.

When comparing states, income tax is just one factor. States with no income tax often have higher property taxes (like Texas at 1.68%) or sales taxes (like Tennessee at 9.55%) to compensate. The total tax burden depends on your income level, homeownership status, spending habits, and specific financial situation. Use our state-by-state calculators above to compare your exact tax liability.

Recent trends show many states moving toward lower and flatter income taxes. Iowa dropped from a top rate of 8.53% to a flat 3.8% in 2025. Georgia switched from progressive to a flat 5.49% in 2024. Several states including Arizona, Idaho, and Montana have also adopted flat tax systems in recent years.

Before analyzing state taxes, it is essential to understand the federal income tax system that applies to all Americans regardless of where they live. The United States uses a progressive federal income tax with seven brackets, meaning different portions of your income are taxed at different rates. A common misconception is that moving into a higher bracket means all your income is taxed at that rate. In reality, only the income within each bracket range is taxed at that bracket's rate.

For the 2025 tax year (filing in 2026), the federal brackets for single filers are:

The standard deduction for 2025 is $15,000 for single filers and $30,000 for married filing jointly. This means a single filer earning $75,000 has a taxable income of $60,000, placing them in the 22% bracket. However, their effective federal tax rate is only about 12.3%, because the first $11,925 of taxable income is taxed at just 10%, the next $36,550 at 12%, and only the remaining $11,525 at 22%.

When evaluating where to live or work based on tax considerations, focusing solely on state income tax rates can be misleading. The total state and local tax burden includes income tax, property tax, sales tax, excise taxes, and various fees. According to the Tax Foundation's 2024 State Business Tax Climate Index, some states with no income tax actually have above-average total tax burdens due to heavy reliance on other revenue sources.

Texas, for example, charges no state income tax but has one of the highest effective property tax rates in the nation at approximately 1.68% (Tax Foundation data). On a $350,000 home, that translates to $5,880 per year in property taxes alone. Combined with an average combined sales tax rate of 8.20%, a Texas resident may actually pay more in total taxes than someone in a low-rate income tax state with modest property and sales taxes.

Washington state also has no income tax but levies one of the highest sales tax rates in the country at 10.25% (combined state and average local). In 2022, Washington also introduced a 7% capital gains tax on gains exceeding $250,000, adding a new dimension to its tax landscape. Meanwhile, New Hampshire has no income or sales tax but offsets this with the sixth-highest property tax rate nationally (1.86%).

The key takeaway is that you must analyze all tax types together. Our state-specific calculators above factor in income tax, property tax, and sales tax for each state.

The American state tax landscape is undergoing a significant transformation. Since 2021, more than 20 states have enacted income tax rate reductions or structural changes, reflecting a national trend toward simpler, flatter, and lower state income taxes. This movement has been driven by both economic competition between states and record-high state tax revenues during the post-pandemic period.

States that recently adopted flat tax systems:

• Iowa: Moved from a progressive system with a top rate of 8.53% to a flat 3.8% in 2025, one of the most dramatic cuts in recent history.
• Georgia: Switched from six progressive brackets (1-5.75%) to a flat 5.49% rate in 2024, with plans to reduce further to 4.99%.
• Arizona: Consolidated from four brackets to a flat 2.5% rate, making it one of the lowest flat-tax states.
• Idaho: Moved to a flat 5.695% rate after previously having graduated brackets up to 6%.
• Mississippi: Eliminated its two lower brackets and is phasing in rate reductions, targeting a flat 4% by 2026.

This trend has significant implications for interstate migration and economic development. The U.S. Census Bureau data shows that states with no or low income tax (Florida, Texas, Tennessee, Nevada) have consistently ranked among the top destinations for domestic migration in 2022-2024. Meanwhile, high-tax states like California, New York, and Illinois have experienced net population outflows. However, correlation does not imply causation. Climate, job opportunities, cost of living, and quality of life also drive migration decisions.

For workers with remote or hybrid jobs, the state tax question has become particularly relevant.

Beyond basic income tax rates, several states have unique tax provisions that can significantly affect your bottom line:

Local income taxes: In addition to state tax, some cities and counties impose their own income taxes. New York City charges up to 3.876% on top of New York State's top rate of 10.9%, potentially pushing the combined state and local income tax rate to nearly 15% for high earners. Other localities with income taxes include Philadelphia (3.75%), Baltimore (3.2%), and various Ohio municipalities. These local taxes are often overlooked when comparing states.

Retirement income taxation: If you are planning for retirement, note that state taxation of Social Security benefits, pensions, and retirement account withdrawals varies significantly. As of 2025, nine states tax Social Security benefits to some degree (Colorado, Connecticut, Minnesota, Montana, New Mexico, Rhode Island, Utah, Vermont, and West Virginia), though most provide exemptions for lower-income retirees. Many states also offer partial or full exemptions for pension income and retirement account distributions.

Estate and inheritance taxes: Twelve states plus DC levy estate taxes, and six states impose inheritance taxes (Maryland has both). The federal estate tax exemption is $13.99 million per individual in 2025, but state thresholds can be much lower. Oregon's estate tax kicks in at just $1 million. Our Estate Tax Calculator can help you estimate potential exposure.

Remote work tax complications: Multi-state taxation has become increasingly complex with the rise of remote work. Some states follow a "convenience of the employer" rule, where remote workers may owe taxes to their employer's state even if they live and work elsewhere. New York, Pennsylvania, Nebraska, and Delaware currently apply this rule, creating potential double-taxation scenarios. Consult a tax professional if you work remotely for an out-of-state employer.
