Missouri property tax appeals, 2027

In Missouri, you appeal a property assessment to the County Board of Equalization, and the deadline is the second Monday in July. Each county below lists its own date, how to file and who hears the appeal. Sale prices are not public record in Missouri, so evidence leans on the county’s own data, listings and independent appraisals.
