Property Tax FAQs

  1. How are my taxes calculated?
    There are two components to property taxes:
    1. Your properties Current Value Assessment (CVA). This is determined by the Municipal Property Assessment Corporation (MPAC);
    2. The total property tax rate. This is determined by the City of Markham, the Region of York, and the Provincial Education portion. (Calculation: Assessment x Tax Rate = Total Property Taxes)

Example: A residential property with an assessed value of $829,995 would pay $5,500.44 for its 2023 property taxes.

      • City of Markham: $829,995 x 0.160816% = $1,334.76
      • Region of York: $829,995   x 0.348892% = $2,895.79
      • Education: $829,995 x 0.153% = $1,269.89
      • Total Tax Levy: $829,995 x 0.662708% = $5,500.44
  1. How is the tax rate determined?
    The tax rate in Markham consists of three (3) portions:
    • City of Markham Portion
    • Region of York Portion
    • Provincial (Education) Portion

    The City establishes a budget to provide municipal services and infrastructure. It calculates a municipal tax rate that will meet its funding needs. The Region of York has a similar process, and the Province of Ontario creates an education tax rate.

  5. How much of the year does the interim tax cover and how is it calculated?

    The City issues two property tax bills each year, with the first being the Interim property tax bill which are issued in early January and reflect 50 per cent of your previous year’s taxes. The second bill reflects the final property taxes which are issued in early June and reflect any budget changes approved by the City, Region and Province. 

    For 2023, your interim property taxes are calculated based on 50% of your 2022 total tax levy. The 2023 final tax bills will be issued in June and will incorporate any budgetary increases approved by the City of Markham, Region of York and the Province of Ontario (Education). As articulated within the 2023 property tax brochure, Markham Council approved the City’s 2023 Budget with a 3 per cent property tax rate increase to assist Markham property owners weather these uncertain and challenging times. The Region of York and the Province are expected to finalize their respective 2023 budgets by April 2023. 

    In summary, the 2023 Final Tax Bills that will be issued in June will include a 3 increase for the City portion, along with any budgetary increase determined by Region and Province in the coming months.

    Please note if you pay your property taxes through the 11 month Preauthorized Tax Payment plan, the interim tax consists of 5 monthly withdraws (Feb – June), whereas the final tax bill consists of 6 monthly withdraws (July – Dec)

  6. My financial institution’s online/telephone banking requires entry of a 15-digit account code to open and pay my taxes. Where can I find the 15-digit account number?
    You need to use the roll number shown on your tax bill. This is your account number.

Property Assessment FAQs

  1. What is the Municipal Property Assessment Corporation (MPAC) 2016 Assessment Update?
    Every four years, MPAC updates the value of every property in the province, which is known as a reassessment. The last reassessment happened in 2016, based on a valuation date of January 1, 2016. This assessment applies to the 2017 to 2023 property tax years.

  2. What is a valuation date?
    Municipal Property Assessment Corporation (MPAC) gives a value to each property based on a specific date. For the 2016 reassessment, the valuation date was January 1, 2016. In this case, MPAC looked at what a willing buyer would have paid for the property on January 1, 2016.

  3. How were the 2016 values determined?
    Municipal Property Assessment Corporation (MPAC) uses the “Current Value Assessment” (CVA) method to come up with a property value. MPAC looks at sales of properties like yours in your area. It also looks at other key factors that affect market value.

    For residential properties, five major factors account for about 85% of a property’s value:
    1. Location
    2. Lot dimensions
    3. Living area
    4. Age of the property (adjusted for any major renovations or additions)
    5. Quality of construction

  7. What happens once a Request for Reconsideration (RfR) has been reviewed?

    If you disagree with the outcome, you can file an appeal with the Assessment Review Board (ARB). The ARB is an independent assessment group. It is an appeal tribunal of the Ontario Ministry of the Attorney General.

    You must file an appeal with ARB within 90 days of your RfR decision. The ARB has its own appeal process. For more information, please contact the Assessment Review Board (ARB).

  8. What happens at an ARB hearing?
    At an ARB hearing, MPAC will attempt to prove that its assessment of the property is correct. MPAC may show supporting documents, such as the sale price of similar properties. Any documents that will be shown at a hearing will be shared with the property owner before the hearing. Property owners can also present evidence at a hearing.
