Input: Context_1 : Taxes in Indiana are almost entirely authorized at the state level, although the revenue is used to fund both local and state level government. The state of Indiana's income comes from four primary tax areas. Most state level income is from a sales tax of 7% and a flat state income tax of 3.3% with another cut coming in 2017 that will bring the rate down to 3.23%. The state also collects an additional income tax for some counties. Local governments are funded by a property tax that is the sum of rates set by local boards, but the total rate must be approved by the Indiana General Assembly before it can be imposed. Residential property tax rates are capped at maximum of 1% of property value. Excise tax is the fourth form of taxation and is charged on motor vehicles, alcohol, tobacco, gasoline, and certain other forms of movable property; most of the proceeds are used to fund state and local roads and health programs. The Indiana Department of Revenue collects all taxes and pays them out to the appropriate agencies and municipalities. The Indiana Tax Court deals with all tax disputes issues, but decisions can be appealed to the Indiana Supreme Court.
