Modifies provisions relating to the ground ambulance service reimbursement allowance tax

HB 1133 modifies Missouri's tax rules for state-run ambulance services. It requires ambulance services owned and operated by the state of Missouri (including state hospitals or departments) to pay an additional ambulance service reimbursement allowance tax, on top of existing fees and taxes, for the privilege of providing ambulance services in the state. The bill clarifies that "engaging in the business" means accepting payment for ambulance services. This policy change directly affects state-owned ambulance providers by adding a new tax obligation. The bill does not alter tax requirements for private ambulance services.
