What is my account number to add as a bill payment for online banking?

The roll number shown on your tax bill is the account number that you will need to use. Please remember no spaces, dashes or decimals.

What happens if my payment is late?

Penalty and interest are charged 15% per annum, applied the first business day of each month on all past due balances. Late payment charges are set in accordance with current legislation and cannot be waived. If payment in full is not received by the installment due date, a property tax arrears notice will be issued and a $5.00 fee will be applied. Failure to receive a bill does not excuse the home owner from payment responsibility.
