However, tax rates and the degree of progressivity vary from state to state. The state income tax in Illinois is a flat tax. Seven states -Wyoming, Washington, Texas, South Dakota, Nevada, Florida, and Alaska- do not impose a state income tax on personal income. Alaska and Florida apply a state income tax to corporate income, South Dakota applies a state income tax to financial institutions, and Washington applies a business and occupation tax that is functionally a state income tax. Tennessee and New Hampshire have a state income tax for interest and dividend income, but not earned income.
