You have four options for paying your bill.

  1. Please mail your payment, along with the bill, to the lockbox address on your bill.
    1. Payments sent to the lockbox must include a bill to be processed.
    2. Your payment will be processed on the day it is received providing the corresponding bill or bills are included.
    3. Checks arriving without the corresponding bill or bills, including checks sent from your bank using a bill pay service, are NOT processed through the lockbox and will be mailed to the Tax Collector’s office at Town Hall. The bills must be looked up and printed in our office. This will delay the payment processing.

If you receive an excise bill for a vehicle you no longer own, please do not ignore it. You may be able to file for an abatement.  Visit the Assessor’s page for more information. Please be aware excise bills should always be paid even if you are filing for an abatement. Bills that are not paid by the due date will be subject to interest and fees.  If you have paid your bill, filed for an abatement and the abatement is granted, you will receive a refund if one is due.
