Municipal Property Assessment Corporation (MPAC) prepares assessments for all properties in Ontario. The assessment is an estimate of market value as of January 1, 2016 (the current base year). 2016 assessed values are phased in over a four year period: 2017-2020. Your assessed value is multiplied by the applicable tax rate to calculate yearly taxes.
2012 (old) market value — $600,000
2016 (new) market value — $850,000
Increase — $250,000 ($62,500 phase-in per year)
Year 1 (2017) = $662,500
Year 2 (2018) = $725,000
Year 3 (2019) = $787,500
Year 4 (2020) = $850,000
If your property or a portion of it is classified as residential, farm, managed forest or conservation land for the 2019 tax year, the deadline to file a Request for Reconsideration (RFR) with the Municipal Property Assessment Corporation (MPAC) is included on your Property Assessment Notice. The Request for Reconsideration deadline for the 2019 tax year is April 1, 2019. If you submit a RFR, the last day to file an appeal is 90 days after the issue date listed on the RFR results letter you receive from MPAC. For all other property types, you may choose to either file a RFR with MPAC or file an appeal directly to the Assessment Review Board (ARB). The Request for Reconsideration deadline for the 2019 tax year is April 1, 2019, and the ARB Appeal deadline is April 1, 2019. RFR forms are available on the MPAC website or by calling 1-866-296-6722. There is a cost to file a formal appeal to the ARB. Forms are available Government of Ontario Assessment Review Board or by calling 1-866-448-2248.
Supplementary and omitted assessments reflect any increase in assessment due to an addition or improvement to a property. If your property is a newly constructed home, it is likely your initial assessment is for the value of the land only. When these situations occur, an assessor from MPAC will assess any additional value. You have the opportunity to appeal this assessment if you believe it is incorrect. Please read your Assessment Notice carefully as there is a deadline for appealing.
