Oklahoma's property taxes are among the lowest in the nation. The property tax, the oldest form of taxation in this country, is a tax on wealth rather than on income or sales. The property tax comprises 17 percent of tax revenue in Oklahoma. This is less than in most other states. Only local governments use property taxes in Oklahoma. Property taxes in Oklahoma were stagnant in the 1980s but have increased steadily since 1992. Property tax revenue has grown eight percent per year since 1998 due to substantial new building and increasing value of existing properties.

The property tax has several advantages as a source of revenue:
There are disadvantages to the property tax as well, including:
Property taxes have traditionally been the main source of revenue for local governments, though this has been less true in Oklahoma than other states. Property taxes are the main source of non-grant revenue for school districts, counties, and vo-tech systems. Cities may use property taxes only to pay the debt on bonds approved by voters. Under the Oklahoma Constitution, property tax rates are limited for each government and purpose and most rate increases require a vote of the people.
Property taxes are paid by most property owners, including homeowners, owners of rental property and businesses. While renters do not pay the tax directly, economists agree that rents typically include at least some of the landlord's cost of property taxes.
Property taxes are administered by county assessors and treasurers, who are elected officials. They must comply with state constitutional and legal provisions that attempt to keep taxes low and somewhat uniform among the 77 counties.
Setting the taxes is a two-step process.
