State and local taxes come from transaction taxes, such as sales tax; income taxes, the money withheld from your paycheck; and property taxes from homeowners. The type and amount of tax varies from state to state and between local communities.
You can visit your state's website to learn more about filing requirements, options, forms, and deadlines. Some states allow you to e-file both your federal and state taxes at once. Such as Delaware, the “Two Birds with One Stone” State.
