Whether you've sold, traded, or junked a vehicle, you must pay the excise tax bill in full by the due date. You must complete the form on the back of the bill, or an abatement application available on the web and forward with the required paperwork to the Assessors' Office. If you are entitled to an abatement, you will receive a refund check after the abatement application has been submitted by you and the application has been approved by the Board of Assessors. Please contact the Assessors' Office with additional questions.
