Modifies provisions relating to motor vehicle assessment valuations

HB 3035 modifies how Missouri assessors value taxable property, primarily affecting property owners and local governments. It establishes a 5% assessment rate for historic motor vehicles (registered under §301.131) and certain older aircraft, while adjusting airport-related property valuations to subtract costs paid by non-government parties for improvements after 2007. The bill also requires counties to use a two-year assessment cycle (odd/even years) and submit annual maintenance plans to the state tax commission for approval. These changes directly impact property tax calculations for specific categories of real and personal property across Missouri.
