Vehicles acquired by rental companies not to be rented for more than 90 days at a time, may be registered and titled by the rental agency exempt from excise tax and sales tax. An Oklahoma title branded "Rental Vehicle" will be issued. If the vehicle is sold less than one (1) year from date of issuance of the title, the rental agency must pay the excise tax plus a 20% penalty on such excise tax before transferring the vehicle, unless the vehicle is being transferred to the manufacturer or its financing company, to a franchised dealer of the same line/make of the vehicle to be transferred, or to anyone, if the vehicle is in a salvage condition (salvage or junk title).
