John, he has already paid the sales tax in his lease payments. When I sold my leased truck, the new buyer and I went to the dealer, he paid the buyout price to the dealer, plus his sales tax and was on his way. The leasee (me) didn't pay a cent. I sold it for more than the buyout, so the buyer had to cut me a check, but didnt have to pay sales tax on that, only on the buyout amount. Hope this makes sense and is helpful.
