What is a “Supplemental” motor vehicle tax bill?

If you newly registered a motor vehicle after October 1, 2009 (first time registration), you will receive a pro-rated tax bill in January 2011, due on January 1, payable by February 1. This “supplemental” bill will reflect the length of time, from the month the vehicle was first registered, through September 30. If you replaced a vehicle and used the same plates to register the replacement vehicle, see answer above.
