Motor Vehicle Excise Tax Bills

Excise bills are mailed throughout the year as we receive the information from the Registry of Motor Vehicles.  

  • The excise bills are due 30 days from the date of issue.  
  • 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.
  • If your excise bill is not paid when due, a demand bill will be issued.
  • If your demand bill is not paid, it will be sent to Deputy Collector, Kelley & Ryan Associates for collection. Once the bill has been sent to Kelley & Ryan, all payments must go through their office. Visit their website by clicking

Please see the multiple options for paying your tax bill below.

    • Payments mailed to the lockbox must be received on or before the due date in order to be processed. Late payments will be mailed to the Tax Collector's office for processing and will accrue interest.
  2. Leave your payment in the payment drop box at Town Hall.

Lockbox payment processing

Eastern Bank processes excise, real estate and personal property tax payments.

The mailing address for payments:

P.O. Box 462, Reading, MA 01867-0862

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 after the due date, 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. This will delay the payment processing.

If you use a bill pay service through your bank, please DO NOT send payment to the lockbox.

Payment Drop Box

Drop box for payments is located to the right of the front doors of the Town Hall.
