Huh? Materials purchased in Michigan to be affixed in Michigan to an aircraft registered or based outside of Michigan should be exempt from sales tax?? So maybe if my car were registered in Indiana and needed a new muffler, which was installed in Traverse City, no sales tax?
Then what, when the aircraft gets to its home state, the owner declares the value of the materials affixed in Michigan and pays the home state's sales tax? Gee, what if the owner, uh, forgets?
This doesn't make sense to me. If something is purchased & used in Michigan--why is it not subject to Michigan sales tax?
Does this have anything to do with a large political donation? Or maybe a small one?
