Kitchener property tax: four instalments in 2026
For 2026 the interim instalments are due on March 2 and May 1. The final residential instalments are due on July 2 and September 1, and the final commercial instalments on September 1 and October 1. The City charges 1.25% a month on late payments, starting the day after the due date and added again on the first business day of each following month until the balance is paid. A late payment is applied to the outstanding penalty and interest first, then to the oldest taxes. The City offers a monthly pre-authorized plan, with withdrawals on the first business day of each month, and a due date plan that follows the interim, final and supplementary bill dates.
