King Township property tax: July and September instalments, and supplementary bills
The Township's 2026 final instalments were due July 30 and September 24, and the interim levy is 50% of last year's annualized taxes. The penalty for late payment is 1.25% per month on the unpaid balance, added on the first day of each month the default continues. The bill carries Township, Region and education taxes, and some bills also include Holland Marsh Drainage System charges and a stormwater levy. When MPAC's assessment rises after a renovation, a new building or a new home becomes occupied, the Township issues a supplementary bill, which can be backdated to the occupancy date and can arrive up to three years later.
