Modifies a provision authorizing a transient guest tax in certain cities

HB 687 allows cities in Missouri's largest charter counties to impose a 5-7% tax on hotel, motel, bed-and-breakfast, and campground stays for tourism promotion and community center operations - but only after voters approve it in an election. The tax must be listed separately on guest bills and collected either by the city or the Missouri state revenue office. It applies specifically to transient guest accommodations and cannot replace existing business license taxes on these businesses. The bill requires a clear voter ballot question and mandates that the tax take effect only after majority approval in an election.
