Renames the state tax commission to the "State Assessment Commission" and modifies provisions relating to the composition and powers of the commission

HB 2439 renames Missouri's "State Tax Commission" to the "State Assessment Commission" and changes its composition. The commission will expand from three to seven members by January 1, 2027, with all members required to have real property appraisal or assessment experience (such as holding a current Missouri appraisal license). The bill also ensures the commission operates independently from the state department of revenue, with the director having no authority over its decisions. Additionally, it sets qualifications including residency requirements and limits the number of commissioners from any single political party to no more than four.
