Vehicles registered between October 2, and the following July 31, will appear on a "Supplemental Motor Vehicle List" provided to the Assessor by the Department of Motor Vehicles. The assessed value of each "supplemental" vehicle is prorated based upon the month of registration. If you traded in a vehicle on the new vehicle and transferred the license plates, all taxes must be paid on vehicle traded in (both installments). You will receive a credit on the supplemental bill based on the total taxes billed on the original vehicle and the date it was traded. Supplemental Motor Vehicle bills are sent out at the end of December and are due in one installment on January 1.
