Modifies provisions relating to property taxes

SJR 66 is a proposed constitutional amendment that would change Missouri's property tax system. It classifies property into three main subclasses (residential, agricultural, and commercial/industrial) and sets a 33.3% cap on assessed value for all classes. The amendment would allow the state legislature to limit annual increases in tax liability for residential and agricultural properties (class 1). This proposal requires voter approval in 2026 to take effect, as it amends Article X of the Missouri Constitution. It directly affects property owners in Missouri, particularly those with residential and agricultural land.
