Property tax is a tax levied or assessed on the owner of property—often real property (real estate)—that is based on the property’s appraised value. Local governments often impose property taxes to finance their school districts, police departments, fire departments, and municipal projects such as construction and maintenance of streets and roads.

Most local government authorities (often counties) allow citizens to dispute or challenge the appraised value of their property through an administrative process initiated with the tax assessor or appraisal district.

In Oklahoma, property tax is primarily administered at the county level by the County Assessor's office. The tax is based on the fair market value of real property, which includes land and the structures attached to it. Property taxes fund local services such as public schools, law enforcement, fire protection, and infrastructure maintenance. Property owners in Oklahoma have the right to challenge the assessed value of their property if they believe it is incorrect. This is typically done by filing a formal appeal with the local County Assessor's office. The appeal process may involve presenting evidence to support the claim for a lower valuation, such as recent sales data for similar properties or an independent appraisal. If the property owner is dissatisfied with the outcome of the appeal at the county level, they may further appeal to the Oklahoma Tax Commission. It is important for property owners to be aware of the deadlines for filing an appeal, as missing these deadlines can result in the loss of the right to challenge the assessment for that tax year.
