I no longer own a vehicle. How do I remove it from being taxed?

The Town of Newtown requires a plate receipt from the Department of Motor Vehicles, and a second form of proof showing what happened to the motor vehicle (please see link for options). The Town of Newtown requires a second from of proof in order to determine the month of adjustment. Unregistered motor vehicles are subject to tax as well which is why the town is unable to take a plate receipt alone in order to remove from the tax role.
