Modifies provisions governing tangible personal property assessments of boats

HB 1631 changes where boat property taxes are calculated in Missouri. It requires motorboats and vessels stored outside an owner's county (e.g., on a lift or in a marina) to be taxed in the county where they’re stored, not the owner’s home county - unless the boat is regularly moved to the owner’s county. This directly affects boat owners who store their vessels long-term outside their residence county. The bill clarifies assessment rules for houseboats, cabin cruisers, and floating docks, ensuring property taxes are tied to the physical location of the boat rather than the owner’s residence.
