I believe he is referring to Georgia’s TAVT tax. If you buy from a private seller, you pay the TAVT when you go down and register the vehicle in your name and get the tag transferred. They won’t forget to ask for it.
No. It was outright SALES TAX that should have been part of the sales since the business (under whom it was titled) actually sold it. NOT a private seller to private seller sale. Whatever this 'used car dealer' is doing probably is very shady, IMO.
