MOTOR VEHICLE SUPPLEMENTAL
Supplemental motor vehicle bills are due January 1st and cover vehicles registered between October 2nd and July 31st of each year. To avoid a penalty, payment must be postmarked, hand-delivered or made online by the first business day of February. Payments made after the first business day of February will incur interest at the rate of 1.5% per month calculated back to the January 1st due date (February interest is 3%; 1.5% for January, 1.5% for February). Taxes are collectible for 15 years from the due date in the State of Connecticut.
If the Assessor provides an adjusted assessment based on sufficient documentation of the disposal of your vehicle, the adjusted tax must be paid in full by the first business day in February; there are no exceptions.
These taxes are pro-rated from the month registered through September at the following percentages of assessed value:
DEADLINE FOR PRESENTATION OF PROOF FOR ADJUSTMENT

The Department of Motor Vehicles does not inform towns when plates are returned or when vehicles are sold, registered out of state or otherwise disposed of.
DEADLINE FOR PRESENTATION OF PROOF
||December 31st 2 years later - or 27 months from the assessment date
The taxpayer forfeits any right to an adjustment of the bill as per Connecticut State Statute (12-71c), if acceptable forms of proof are not received by the Assessor by the deadline.
