My 15-year old son worked very hard on the family farm to earn $12,000 to purchase a hard-driven 2016 Chevrolet Silverado. When he presented the Bill of Sale to SGI, the Government of Saskatchewan refused to accept it. They charged him PST based on a book value of $24,000. The Government of Saskatchewan collected PST once on the initial sale, then collected PST again on the resale to my son, then collected PST a third time by falsely claiming the vehicle was worth double what it was.
