Where the purchaser of a motor vehicle, trailer, boat or outboard motor receives a rebate from the seller or manufacturer, the tax imposed by sections 144.020 and 144.440 shall be computed only on that portion of the purchase price which exceeds the amount of the rebate, if there is a bill of sale or other record showing the actual rebate given by the seller or manufacturer. Where the trade-in or exchange allowance plus any applicable rebate exceeds the purchase price of the purchased article there shall be no sales or use tax owed. This section shall also apply to motor vehicles, trailers, boats, and outboard motors sold by the owner or holder of the properly assigned certificate of ownership if the seller purchases or contracts to purchase a subsequent motor vehicle, trailer, boat, or outboard motor within one hundred eighty days before or after the date of the sale of one or more previously-owned motor vehicles, trailers, boats, or outboard motors, or any combination thereof, and all related bills of sale showing the paid sale price are presented to the department of revenue at the time of licensing. A copy of all such bills of sale shall be left with the licensing office. Where the subsequent motor vehicle, trailer, boat, or outboard motor is titled more than one hundred eighty days after the sale of one or more motor vehicles, trailers, boats, or outboard motors, or any combination thereof, the allowance pursuant to this section shall be made if the person titling such article establishes that the purchase or contract to purchase was finalized prior to the expiration of the one hundred eighty-day period and presents to the department of revenue a copy of all such bills of sale.
