Property tax is one of the largest ongoing costs of homeownership in Markham, Ontario — yet it is also one of the least understood. Many Markham home buyers budget carefully for their mortgage, Land Transfer Tax, and legal fees, then are surprised by the size of their annual property tax bill after closing. Michael John Lau and Neeraj Moolchandani at Kaizen Real Estate Team include a property tax estimate in every Markham buyer's closing cost projection — ensuring buyers arrive financially prepared for every cost of owning a home in Markham, Ontario.
How Markham Property Taxes Are Calculated
Property taxes in Markham, Ontario are calculated by multiplying the property's assessed value — set by the Municipal Property Assessment Corporation (MPAC) — by the combined property tax rate for the City of Markham and York Region.
Markham's total residential property tax rate for 2024 was approximately 0.628% of assessed value.
Understanding this formula is important for every Markham home buyer because the MPAC assessed value of a property may differ significantly from its current market value — and the difference directly affects how much property tax a Markham homeowner pays each year.

These estimates are based on approximate MPAC assessed values and Markham's combined residential tax rate. Actual property tax bills may vary — Michael John Lau and Neeraj Moolchandani provide property-specific estimates for every Markham home a buyer is considering.
| Property Type in Markham | Approx. Purchase Price | Approx. MPAC Assessment | Estimated Annual Property Tax |
|---|---|---|---|
| Markham Condominium | $600,000–$750,000 | $450,000–$550,000 | $2,800–$3,450/yr |
| Markham Freehold Townhome | $800,000–$950,000 | $600,000–$720,000 | $3,750–$4,500/yr |

What Is MPAC — and How Does It Affect Your Markham Property Tax?
The Municipal Property Assessment Corporation (MPAC) is the independent organization responsible for assessing the value of every property in Ontario — including every home in Markham. MPAC uses a market-based approach to determine assessed value, evaluating comparable sales in the area around the property being assessed.
Key facts every Markham homeowner and buyer should understand about MPAC assessments:
- MPAC assessed value is not the same as market value. In many Markham neighbourhoods, MPAC assessed values lag behind current market values due to assessment cycles — meaning a Markham home selling for $1.3M today may still carry an MPAC assessed value of $950,000 or lower based on an older assessment cycle.
- Ontario conducts property reassessments periodically. When Ontario conducts a province-wide reassessment, MPAC values are updated across all Markham properties — which can result in increases to annual property tax bills for homeowners whose assessed values have risen.
- New construction in Markham is assessed upon first occupancy. Buyers of new construction homes in Markham should anticipate that MPAC will assess the completed property after closing — and that the first full-year property tax bill may be higher than any interim estimates provided during the pre-construction period.
- MPAC assessment notices are mailed to every Ontario property owner. Every Markham homeowner who receives an MPAC assessment notice has the right to review the assessment and file a Request for Reconsideration if they believe the assessed value is incorrect.
How Markham Property Taxes Compare to Other GTA Municipalities
Markham, Ontario's property tax rate is among the lower residential rates in the Greater Toronto Area. The City of Toronto charges a substantially higher property tax rate than Markham — meaning a Markham homeowner with a comparable MPAC assessed value pays significantly less in annual property tax than an equivalent Toronto homeowner.
| GTA Municipality | Approx. 2024 Residential Tax Rate | Annual Tax on $800K Assessment |
|---|---|---|
| City of Toronto | ~0.666% | ~$5,328/yr |
| City of Markham | ~0.628% | ~$5,024/yr |
| City of Vaughan | ~0.647% | ~$5,176/yr |
| City of Richmond Hill | ~0.659% | ~$5,272/yr |
| City of Mississauga | ~0.721% | ~$5,768/yr |
| City of Brampton | ~0.962% | ~$7,696/yr |
Markham's competitive property tax rate — combined with the city's strong municipal services, infrastructure investment, and quality of life — makes homeownership in Markham, Ontario one of the most financially attractive options in the Greater Toronto Area on a total cost-of-ownership basis.
How to Appeal Your Markham Property Tax Assessment
Markham homeowners who believe their MPAC assessed value is too high have the right to formally challenge the assessment through Ontario's property tax appeal process. Michael John Lau and Neeraj Moolchandani recommend that every Markham homeowner review their MPAC assessment notice carefully — particularly following a province-wide reassessment cycle.
Property Tax Adjustments at Closing: What Markham Buyers Must Know
When a Markham home is purchased, property taxes are adjusted between the buyer and seller at closing. If the seller has prepaid property taxes for a period that extends beyond the closing date, the buyer reimburses the seller for the prepaid portion. If property taxes are in arrears at closing, the seller's proceeds fund the outstanding balance.
- Tax adjustment at closing — buyer reimburses seller for prepaid Markham property taxes covering the period after the closing date; amount varies by closing timing within the tax payment cycle
- Interim tax bills for new construction — buyers of new Markham construction homes should anticipate that MPAC assessment and the first full property tax bill may arrive 6 to 18 months after closing
- Property tax included in mortgage payment — many Markham lenders collect a monthly property tax installment as part of the mortgage payment and remit it directly to the City of Markham on the homeowner's behalf
- Ontario Senior Homeowners' Property Tax Grant — eligible Markham senior homeowners may qualify for a provincial property tax grant of up to $500 annually; eligibility is based on income and OAS qualification
