When a dealer sells you a vehicle, the taxes that are included are “sales” tax. The bill that you received is for county property taxes. You have a 120 day grace period from the date of purchase of your new vehicle in which to pay the county property tax due on your vehicle. If you do not pay the taxes due by the due date, a notice will be sent to the Department of Motor Vehicles to suspend your drivers license. If your drivers license is suspended for non-payment of property taxes and you also hold a Commercial Drivers License (CDL), it will also be affected by the suspension.
