I'm looking to purchase a can. Which would be the best route to take? File under an S or C? Still form a trust? I am president of a 3 FL corps (2 S, one C) The corps are active, so the yearly corp fees are irrelevant. Whats the story on other NFA items.. conversion to FA etc? Are the tax stamps around the same price? Can you just purchase the FA sear/parts? School a noob.
