Your account number is your roll # consisting of 19 digits starting with 11 24...and ending with ..0000.

The Tax Department offers a Pre-authorized payment plan for both Due Date or monthly installments. For further information or to submit a request to be placed on a payment plan, please click on the following links.


Please Note:  Many property owners include their tax payment with their mortgage payment and let the bank worry about paying the taxes on time. Talk to your mortgage company advisor if you are interested in this method.


Interest is calculated on the first day of each month at rate of 1.25% (or 15 % per annum.) on past due tax amounts. When a payment is made it is applied to interest in every outstanding year firstly and then is applied to taxes outstanding starting with the most past due.
