Laws vary from state to state, but property tax is often a locally assessed and locally administered tax (by counties)—and in those states there is no state property tax. Property tax brings in the most money of all taxes available to local government to pay for schools, roads, police and firemen, emergency response services, libraries, parks, and other services provided by local government.

Most states offer a variety of partial or total (absolute) exemptions from appraised property values used to determine local property taxes. A partial exemption removes a percentage or a fixed dollar amount of a property's value from taxation. A total (absolute) exemption excludes the entire property from taxation. Taxing units (government entities) may be required by the state to offer certain (mandatory) exemptions and have the option to decide locally on whether or not to offer others (local option).

Exemptions from property tax usually require the taxpayer to apply for the exemption. Applications for property tax exemptions are filed with appraisal districts, and deadlines may vary. Appraisal district chief appraisers are responsible for determining whether a property qualifies for an exemption.
Exemptions are usually located in a state’s tax code (statutes) and exemption requirements are often extensive. Property owners should read these statutes carefully.

Common exemptions are for properties that qualify as a residence homestead or are eligible for charitable, religious, or agricultural exemptions, as provided by the state’s tax laws. Disabled persons, senior citizens (age 65 or older), veterans, and surviving spouses of veterans who were killed in action (KIA) are also eligible for exemptions in some states.

In Missouri, property tax is primarily a local tax administered by local governments, including counties and municipalities. The revenue from property taxes is used to fund various local services such as schools, roads, emergency services, and parks. Missouri law provides for several types of property tax exemptions, which can be partial or total. Partial exemptions reduce the taxable value of the property by a certain percentage or dollar amount, while total exemptions completely remove the property from the tax rolls.

Mandatory exemptions are required by state law, and local governments may also offer additional exemptions at their discretion. Property owners must typically apply for exemptions through their local appraisal district, and there are deadlines for these applications. The chief appraiser of the appraisal district determines eligibility for exemptions.

Common exemptions in Missouri include those for primary residences (homestead exemption), as well as for agricultural, religious, and charitable properties. Additionally, Missouri offers property tax relief for seniors (65 and older), disabled individuals, veterans, and surviving spouses of veterans. Property owners should consult the Missouri state tax statutes for detailed requirements and eligibility criteria for property tax exemptions.
