State Individual Income Tax Rates and Brackets, 2023

9 min readBy: Timothy Vermeer

Key Findings

  • Individual income taxes are a major source of state government revenue, accounting for 40 percent of state tax collections in fiscal year 2020, the latest year for which data are available.
  • Forty-three states and the District of Columbia levy individual income taxes. Forty-one taxA tax is a mandatory payment or charge collected by local, state, and national governments from individuals or businesses to cover the costs of general government services, goods, and activities. wage and salary income. New Hampshire exclusively taxes dividend and interest income while Washington only taxes capital gains income. Seven states levy no individual income taxAn individual income tax (or personal income tax) is levied on the wages, salaries, investments, or other forms of income an individual or household earns. The U.S. imposes a progressive income tax where rates increase with income. The Federal Income Tax was established in 1913 with the ratification of the 16th Amendment. Though barely 100 years old, individual income taxes are the largest source of tax revenue in the U.S. at all.
  • Of those states taxing wages, 11 have single-rate tax structures, with one rate applying to all taxable incomeTaxable income is the amount of income subject to tax, after deductions and exemptions. For both individuals and corporations, taxable income differs from—and is less than—gross income. . Conversely, 30 states and the District of Columbia levy graduated-rate income taxes, with the number of brackets varying widely by state. Hawaii has 12 brackets, the most in the country.
  • States’ approaches to income taxes vary in other details as well. Some states double their single-filer bracket widths for married filers to avoid a “marriage penaltyA marriage penalty is when a household’s overall tax bill increases due to a couple marrying and filing taxes jointly. A marriage penalty typically occurs when two individuals with similar incomes marry; this is true for both high- and low-income couples. .” Some states index tax brackets, exemptions, and deductions for inflationInflation is when the general price of goods and services increases across the economy, reducing the purchasing power of a currency and the value of certain assets. The same paycheck covers less goods, services, and bills. It is sometimes referred to as a “hidden tax,” as it leaves taxpayers less well-off due to higher costs and “bracket creep,” while increasing the government’s spending power. ; many others do not. Some states tie their standard deductions and personal exemptions to the federal tax code, while others set their own or offer none at all.

Individual income taxes are a major source of state government revenue, accounting for 40 percent of state tax collections. Their prominence in public policy considerations is further enhanced by individuals being actively responsible for filing their income taxes, in contrast to the indirect payment of sales and excise taxes.

Forty-three states levy individual income taxes. Forty-one tax wage and salary income. New Hampshire exclusively taxes dividend and interest income while Washington only taxes capital gains income. Seven states levy no individual income tax at all.

Of those states taxing wages, eleven have single-rate tax structures, with one rate applying to all taxable income. Conversely, 30 states and the District of Columbia levy graduated-rate income taxes, with the number of brackets varying widely by state. Kansas, for example, is one of several states imposing a three-bracket income tax system. At the other end of the spectrum, Hawaii has 12 brackets. Top marginal rates range from Arizona’s 2.5 percent to California’s 13.3 percent.

In some states, a large number of brackets are clustered within a narrow income band. For example, Georgia’s taxpayers reach the state’s sixth and highest bracket at $7,000 in taxable income. In other states, the top rate kicks in at a much higher level of marginal income. For example, the top rate kicks in at or above $1 million in California (when the “millionaire’s tax” surcharge is included), Massachusetts, New Jersey, New York, and the District of Columbia.

Table 1 shows how each state’s individual income tax is structured.

States’ approaches to income taxes vary in other details as well. Some states double their single-filer bracket widths for married filers to avoid imposing a “marriage penalty.” Some states index tax brackets, exemptions, and deductions for inflation, while many others do not. Some states tie their standard deductions and personal exemptions to the federal tax code, while others set their own or offer none at all.

The federal Tax Cuts and Jobs Act of 2017 (TCJA) increased the standard deductionThe standard deduction reduces a taxpayer’s taxable income by a set amount determined by the government. It was nearly doubled for all classes of filers by the 2017 Tax Cuts and Jobs Act (TCJA) as an incentive for taxpayers not to itemize deductions when filing their federal income taxes. (set at $13,850 for single filers and $27,700 for joint filers in 2023) while suspending the personal exemption by reducing it to $0 through 2025. Because many states use the federal tax code as the starting point for their own standard deduction and personal exemption calculations, some states that previously linked to these provisions in the federal tax code have updated their conformity statutes in recent years to either adopt federal changes, retain their previous deduction and exemption amounts, or retain their own separate system but increase the state-provided deduction or exemption amounts.

In the following tables, we have compiled the most up-to-date data available on state individual income tax rates, brackets, standard deductions, and personal exemptions for both single and joint filers. After the tables, we document notable individual income tax changes implemented in 2022.

(a) Local income taxes are excluded. Eleven states have county- or city-level income taxes; the average rates expressed as a percentage of AGI within each jurisdiction are: AL--0.10%; DE--0.16%; IN--0.61%; IA--0.11%; KY--1.31%; MD--2.38%; MI--0.17%; MO--0.21%; NY--1.59%; OH--1.56%; PA--1.22%. In CA, CO, KS, NJ, OR, and WV some jurisdictions have payroll taxes, flat-rate wage taxes, or interest and dividend income taxes. See Jared Walczak, “Local Income Taxes in 2019,” Tax Foundation, July 30, 2019, https://taxfoundation.org/local-income-taxes-2019/. +256:293+256:289"
(b) These states allow some or all of federal income tax paid to be deducted from state taxable income.

Notable 2023 State Individual Income Tax Changes

Last year continued the historic pace of income tax rate reductions. In 2022, 12 states enacted individual income tax rate reductions, a continuation from 2021 when 13 states enacted or implemented individual income tax rate reductions. Nearly all of the 2022 rate reductions were effective starting January 1, 2023. Georgia’s rate reduction will occur in 2024 along with additional reductions in Iowa, Mississippi, and Nebraska. Some of the scheduled future rate reductions rely on tax triggers, where rate reductions will occur once certain revenue benchmarks are met. Other rate reductions are set to occur on specific future dates, with rates phasing down incrementally over time. Massachusetts was the only jurisdiction to enact an individual income tax rate increase in 2022. Notable changes to major individual income tax provisions include the following:

Arizona

Arizona joined the growing list of states with a flat individual income tax structure, one year earlier than originally anticipated. Under S.B. 1828, tax triggers were established that set the state on a course to a 2.5 percent flat rate subject to reaching specified revenue targets. Since Arizona reached the final revenue target sooner than anticipated, the rate schedule converted directly from a two-bracket structure with rates of 2.55 and 2.98 percent to a flat rate of 2.5 percent, without the need for another year of a two-rate structure.

Arkansas

In August 2022, Arkansas legislators passed H.B. 1002, a bill to accelerate previously planned individual and corporate income taxA corporate income tax (CIT) is levied by federal and state governments on business profits. Many companies are not subject to the CIT because they are taxed as pass-through businesses, with income reportable under the individual income tax. rate reductions. The reduction in the top marginal individual income tax rate from 5.5 to 4.9 percent was retroactive to January 1, 2022.

Idaho

In September 2022, Idaho legislators enacted H.B. 1 to convert the individual income tax structure to a flat rate of 5.8 percent, down from a top marginal rate of 6 percent. As this law was designed in part to supersede a tax increase proposal that was approved for the ballot but later withdrawn, the law technically took effect January 3, 2023, but its provisions apply retroactively to January 1, 2023.

Indiana

Under H.B. 1002, enacted in March 2022, Indiana’s flat individual income tax rate was reduced from 3.23 to 3.15 percent effective for 2023 and 2024. Additional triggers are in place that could reduce the rate to 2.9 percent by 2029 if specified conditions are met.

Iowa

Iowa enacted comprehensive tax reforms in 2018, 2021, and 2022, and many of these reforms will continue phasing in over the coming years. Effective January 1, Iowa’s nine individual income tax rates were consolidated into four, and the top rate was decreased from 8.53 to 6 percent. Iowa’s graduated-rate tax structure is scheduled to shift to a flat taxAn income tax is referred to as a “flat tax” when all taxable income is subject to the same tax rate, regardless of income level or assets. at a rate of 3.9 percent in 2026.

Additionally, effective tax year 2023, the standard deduction and state deduction for federal taxes paid are repealed, broadening the base to help pay for reductions to the rate.

Kentucky

In April 2022, H.B. 8 was enacted, reducing individual income tax rates. Many of the law’s provisions took effect on January 1, 2023, including the initial reduction in the individual income tax rate from 5 to 4.5 percent.

The law also established tax triggers that, contingent upon revenue meeting certain benchmarks, could phase down the individual income tax rate to zero over many years, starting with a likely further reduction from 4.5 to 4 percent in 2024.

Massachusetts

The narrow passage of Massachusetts Question 1, a legislatively referred constitutional amendment, in November 2022 modified the state’s constitution to add a 4 percent surtaxA surtax is an additional tax levied on top of an already existing business or individual tax and can have a flat or progressive rate structure. Surtaxes are typically enacted to fund a specific program or initiative, whereas revenue from broader-based taxes, like the individual income tax, typically cover a multitude of programs and services. to the current 5 percent individual income tax rate for annual income above $1 million. Massachusetts had a flat-rate individual income tax since 1917.

Mississippi

Mississippi moved to a flat individual income tax structure as a result of H.B. 531, enacted in April 2022. Effective January 1, 2023, the 4 percent tax on taxable income between $5,000 and $10,000 was eliminated, leaving a single rate of 5 percent on income exceeding $10,000. The flat rate is scheduled to phase down to 4.7 percent in 2024, 4.4 percent in 2025, and 4 percent in 2026.

Missouri

In October 2022, Missouri legislators passed S.B. 3, a bill to expedite planned individual income tax rate reductions and replace existing tax triggers with triggers that reduce the top marginal rate further and faster than planned in previous legislation enacted in 2014 and 2021. Effective January 1, Missouri’s top marginal individual income tax rate was reduced from 5.3 to 4.95 percent, and the amount of income exempt from Missouri’s individual income tax rates increased from $100 to $1,000. Additional triggers seek to eventually reduce the top rate to 4.5 percent.

Nebraska

Under L.B. 873, enacted in April 2022, Nebraska plans to reduce its top marginal individual income tax rate to 5.84 percent by 2027. The tax will be reduced by 0.2 percentage points per year. The initial reduction from 6.84 to 6.64 percent occurred on January 1, 2023.

New Hampshire

New Hampshire began phasing out its income tax on interest and dividend income in 2023, bringing the rate down from 5 to 4 percent. This is the result of H.B. 2, enacted in June 2021. The rate is scheduled to phase down by one percentage point per year until the tax is phased out entirely in 2027.

New York

New York’s budget for fiscal year 2023, enacted in April 2022, accelerated income tax rate reductions originally passed in 2016 for middle-income earners. Under S. 8009, rate reductions originally scheduled for 2025 took effect two years earlier than planned, bringing the rate on income between $13,900 and $80,650 (single filers) and between $27,900 and $161,550 (joint filers) to 5.5 percent and bringing the rate on income between $80,650 and $215,400 (single filers) and between $161,500 and $323,200 (joint filers) to 6 percent. For tax year 2022, the tax rates on those levels of income were 5.85 and 6.25 percent, respectively.

North Carolina

North Carolina’s flat individual income tax rate decreased from 4.99 to 4.75 percent for 2023 as a result of SB 105, the 2021 Appropriations Act, which was enacted in November 2021. Future scheduled reductions enacted under this same law will ultimately bring the rate to 3.99 percent by 2027.
