Understanding Your Assessment - Property Value and Property Taxes
How you are assessed:
- The principal benchmark used to assess property is current value (market value, actual value).
- Current value is considered to be the most likely selling price a willing buyer would pay and a willing seller would accept in an open market, where both parties are under no pressure either to buy or sell the property.
- When fairly assessed, similar properties located in a similar area will be assessed at a similar rate, resulting in the payment of similar taxes.
- It is important to note that there are five (5) major factors which account for 85% of the home’s value
- 1. Location
- 2. Living area (square feet)
- 3. Age of the property
- 4. Lot size (lot dimensions)
- 5. Quality of construction
Every four (4) years, MPAC conducts a province-wide assessment update and mails property assessment notices (PANs) to every property in Ontario.
The next update was to have been completed in 2020, and every property owner in Ontario would have received a property assessment notice (PAN) from MPAC updating the value of their property based on a valuation date of January 1, 2019. Notices were expected to be delivered in the second half of 2020.
Under the phase-in provisions in the Assessment Act:
a) Increase in assessed value is introduced gradually over four years (25% each year).
b) Decrease in assessed value is introduced immediately.
What if I disagree with my assessed value or classification?
