Modifies provisions governing tax rate ceiling increases

HB 1497 adjusts how local governments in Missouri (like counties and school districts) set property tax rates when property values change. It requires these entities to revise tax rates to maintain the same total revenue from property taxes as the previous year, without exceeding the highest voter-approved rate from prior years. The bill establishes specific formulas for calculating these adjustments, including limits based on inflation (capped at the Consumer Price Index or 5%) and rules for handling property reassessments or value changes. This directly affects all political subdivisions that levy property taxes, ensuring revenue stability while preventing automatic rate increases beyond voter-approved ceilings.
