Average retail price
We use the Price Digest’s Aircraft Bluebook Historical Value Reference. For aircraft not listed (i.e. kits, assembled from parts, experimental), we determine the average retail price based on the average price of similar aircraft being offered for sale.
The average retail price used for calculating the tax is the purchase amount from the year it was first required to be registered.
Please note, a bill of sale with a nominal value such as “$1 and other valuable consideration” will not be considered adequate documentation of the purchase price.
