Title 26 › Subtitle Subtitle D— Miscellaneous Excise Taxes › Chapter 31— RETAIL EXCISE TAXES › Subchapter C— Heavy Trucks and Trailers › § 4053
Certain truck-related items escape the federal retail tax that normally applies to heavy trucks and trailers under section 4051. No tax is charged on camper units built to sit on a truck and serve as living quarters, house trailers, ambulances, hearses, or bodies built to haul, spread, or load feed, seed, or fertilizer on farms. Concrete-mixing equipment mounted on truck chassis, trash containers not permanently attached to a truck, and trailers built to run on both highways and railroad tracks are also exempt. The exemption also covers mobile machinery: a chassis that exists only to carry permanently mounted construction, farming, mining, or similar equipment, and that could not haul anything else without major structural changes. Finally, idling-reduction devices that give a parked truck heat, air conditioning, or electricity without running the main engine (if the EPA approves them as idle reducers) and insulation rated at least R35 per inch are tax-free.
