I am eligible for GST Exempt Car Parts.
My understanding is - consumables and accessories are not GST exempt, but parts that are on or in the vehicle and will be replaced are GST exempt.
How does this apply to item that some would call “accessories” but you cannot buy the car without them? For example, side steps and roof racks. My vehicle came with them (new from dealer) and I couldn’t get it without them on it. I want to replace the sidesteps from the dealer ones to more durable ones. Would these be GST exempt, as all models of this vehicle come with side steps from factory and you cannot get it without them, or does this count as an accessory?
