Pursuant to State law, interest at the rate of 8% is charged on all past-due property taxes, and 14% interest is charged on all property tax liens. If you are unable to pay your property taxes or tax lien in full, making partial payments will benefit you by reducing the total interest that must be paid. Upon receiving your partial payment, the Tax Collector's Office will mail you a receipt showing how your payment was applied and the remaining balance due - which you may then use as a reminder for your next payment. Payment Options: Cash, checks, money orders are accepted at the Tax Collectors Office. Checks or money orders by mail. Check or money orders may be placed in the 24 hour secure drop-box located on the right-hand side of the Town Hall (outside the elevator entrance).
