Haw. Code R. § 18-251-1-02
this chapter, "lessor" means any person in the business of providing rental motor vehicles or vehicles to the public and includes any person operating a peer-to-peer car-sharing marketplace.
Example 1:
ABC U-Drive (ABC) owns 100 cars and is in the business of providing cars to customers for a fee. ABC is the lessor of these cars, and the incidence of the rental motor vehicle surcharge tax is on ABC.
Example 2:
Giro Transportation (Giro) is a peer-to-peer car-sharing marketplace company that provides a forum where prospective rental motor vehicle lessees may browse for cars they wish to rent. Giro enters into an agreement with car owners to provide cars to lessees for ground transportation. The lessee pays Giro the rental amount for the car and takes possession from the owner. The surcharge tax is imposed on Giro, not the owner, because Giro is the lessor, Giro provided the lessee a rental vehicle for a fee, and Giro is not a wholesaler, tour packager, nor travel agent. The owner is a wholesaler and is not subject to the tax under this chapter.
Example 1:
Vacation Services (Vacation) is a tour packager company that arranges a variety of visitor industry services, such as air transportation, hotel room accommodations, ground transportation, tours, classes, and luaus into packages, and sells these services to tourists. ABC U-Drive (ABC) enters into an agreement with Vacation to provide the cars for ground transportation. When the customer receives a rental car from ABC, the rental motor vehicle surcharge tax is triggered, and the surcharge tax is imposed on ABC, not Vacation, because Vacation is a tour packager who arranged rental vehicle transportation.
Example 2:
Vacation Services (Vacation) decides that its business would become more profitable if it started to use its own cars instead of making arrangements with ABC U-Drive. Vacation acquires 5 cars and provides them to customers for a fee. Vacation is now the lessor of these cars, and the rental motor vehicle surcharge tax is imposed on Vacation."
