Modifies provisions governing the assessment and taxation of property

HB 3271 modifies how Missouri counties and local governments adjust property tax rates after reassessments. It requires political subdivisions (like cities, school districts, and counties) to revise tax rates for specific property classes to maintain the same total tax revenue as the previous year, excluding new construction and certain property types. The bill sets limits on these adjustments, ensuring rates do not exceed the highest voter-approved rate for that property class or the rate adjusted for inflation (capped at 5% or the Consumer Price Index, whichever is lower). This primarily affects local governments managing property taxes, ensuring revenue stability while respecting voter-approved tax ceilings.
