There are two guys here in NC that built a $250K homebuilt and didn't pay any sales tax until it was an "airplane". It turns out NC puts a cap on sales tax for an airplane and after it was flying, they wrote that check and IIRC, it was something like $3500.
NC also has annual property tax on planes, boats, cars, motorcycles, trailers, etc. The good news is we can set the tax amount and then it depreciates from that point on, same as a car.
I would like to hear from others in NC about capping the property tax to the builders of planes, boats, cars, etc. to the original builder. If the vehicle is sold, then the buyer would pay based on the purchase price. Realizing that local governments are trying to maximize tax revenue, this might be difficult. However, if any of you have any experience with changing laws, please contact me.
