Income Tax by State 2024

In the United States, each state has its own policy for collecting income taxes. Income taxes are just one of the ways that state governments make revenues for operations – think of things like building schools and repairing roads. Of the 50 states, a total of 43 have some form of state income tax.

In 41 states, wages and salaries are taxed. In New Hampshire, only interest income and tax dividends are taxed at a rate of 4%, but not personal income tax. Similarly, Washington has a tax rate of 7%, but this is only on capital gains income. In the remaining seven states, there is no state income tax. However, the state makes revenue through other forms of taxation, such as higher property tax rates or higher sales tax rates.

These aren’t the only differences among the states when it comes to income taxes, either. For example, some states have their own deductions and exemptions, others use rates based on the federal tax code, while other states don’t allow any deductions or exemptions. Some states have different brackets for married and single tax filers.
