All these costs were borne by Flying Wing Star, which then obtained certifications from the Star Sector Government, the Military Affairs Department, and the Imperial Navy, and used them to settle accounts with the Empire to offset taxes.
In the past decade, the amounts paid by Flying Wing Star annually for the Star Sector Government and Naval Academy varied, sometimes being five or six hundred million, and at times over a billion.
This enormous tax offset, coupled with the contributions from the shipyard's ship payments, constituted the structure of Flying Wing Star's payment of Imperial Tax. Sometimes, during periods when the Flying Wing Star Shipyard happened to be in a cycle of producing large ships, the cost of the ships plus the tax offset meant that not only could the Empire not collect any additional money from Flying Wing Star, instead, it often had to give back quite a sum.
However, how could there not be any tricks involved in these matters?
