The elected county assessor values all real estate in the county (in St. Louis City, the city assessor). The county Board of Equalization hears appeals. In most counties the county clerk, as the board's secretary, takes the appeal forms. Some large counties, such as St. Louis County and Jackson County, take appeals through their own Board of Equalization office, mostly online. In St. Louis City, appeals go through the assessor's office. Find your county for contact details, local tax figures and a step-by-step guide.
