Modifies provisions relating to motor vehicle assessments

This bill updates the rules for how property assessors in Missouri calculate and record property tax values. It changes the percentage of true value used to assess different types of real property, such as residential and commercial land, and adjusts the rates for specific personal property items like historic vehicles, aircraft, and farm machinery. The legislation also clarifies how assessors must handle new construction, establishes procedures for resolving disputes over assessment plans, and sets a legal presumption that computer-generated valuations are accurate unless proven otherwise.
