Ranking Individual Income Taxes on the 2023 State Business Tax Climate Index

This week’s map examines states’ rankings on the 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. component of our 2023 State Business Tax Climate Index. The individual income 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. is important to businesses because states tax sole proprietorships, partnerships, and, in most cases, limited liability companies (LLCs) and S corporations under the individual income tax code. However, even traditional C corporations are indirectly impacted by the individual income tax, as this tax influences the location decisions of individuals, potentially impacting the state’s labor supply, and higher individual income taxes increase the price of labor. States with gross receipts taxes also extend those to pass-through businessA pass-through business is a sole proprietorship, partnership, or S corporation that is not subject to the corporate income tax; instead, this business reports its income on the individual income tax returns of the owners and is taxed at individual income tax rates. es in addition to C corporations, which is also accounted for in this component of the Index.

States that score well on the Index’s individual income tax component usually have a flat, low-rate income tax with few deductions and exemptions. They also tend to protect married taxpayers from being taxed more heavily when filing jointly than they would filing as two single individuals. In addition, states perform better on the Index’s individual income tax component if they index their brackets, deductions, and exemptions 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. to avoid unlegislated tax increases.

States with a perfect score on the individual income tax component (Alaska, Florida, South Dakota, and Wyoming) have no individual income tax and no payroll taxA payroll tax is a tax paid on the wages and salaries of employees to finance social insurance programs like Social Security, Medicare, and unemployment insurance. Payroll taxes are social insurance taxes that comprise 24.8 percent of combined federal, state, and local government revenue, the second largest source of that combined tax revenue. es besides the unemployment insurance tax. The next highest-scoring states are Nevada, Tennessee, Texas, Washington, and New Hampshire.

Nevada taxes wage income at a low rate under the state’s Modified Business Tax but does not tax investment income. New Hampshire taxes interest and dividend income but not wage income. Tennessee, Texas, and Washington do not tax wage income but don’t receive a perfect score on this component because they apply their gross receipts taxes to S corporationAn S corporation is a business entity which elects to pass business income and losses through to its shareholders. The shareholders are then responsible for paying individual income taxes on this income. Unlike subchapter C corporations, an S corporation (S corp) is not subject to the corporate income tax (CIT). s, which, in most states, would be taxed under individual income tax codes. (Washington and Texas also apply these to limited liability corporations.)

Other states that score well on the individual income tax component are Utah, Massachusetts, Michigan, Illinois, Colorado, Indiana, Arizona, and North Carolina, because they all have a single, low tax rate. It’s worth noting that, while Massachusetts had a single rate income tax on July 1, 2022 (the snapshot date of the current edition of the Index), the state now has a two-bracket income tax system with a high top rate as of January 1, 2023, and will thus score much lower in the future.

States that score poorly on this component tend to have high tax rates and very progressive bracket structures. They generally fail to index their brackets, exemptions, and deductions for inflation, do not allow the deduction of foreign or other state taxes, penalize married couples filing jointly, do not include LLCs and S corporations under the individual income tax code (instead taxing them as C corporations), and may impose an alternative minimum tax (AMT). The poorest-performing states on this year’s individual income tax component are New York, California, New Jersey, Connecticut, and Hawaii.

High marginal rates adversely affect labor output and investment and can influence location decision-making, especially in an era of enhanced mobility, where it is easier for individuals to move without jeopardizing their current job, or without limiting the scope of their search for a new one.
