Property taxes are an important source of revenue for local schools, vocational-technical education, libraries, city and county government. As in most states in the United States, property taxes are the backbone of funding of local government and schools. Oklahoma's property tax with some changes has fulfilled this basic function since statehood.
Generally, local schools receive the largest share of the property tax. Schools are followed by city bond issues, county government, vocational-technical schools, libraries, and city-county health department. Except for those provided for in the Oklahoma Constitution, millage levies are controlled by the voters.
As noted in the chart, ad valorem revenues in a typical year are distributed among several groups.
