Markham property tax is calculated by multiplying your home’s MPAC assessed value by the combined municipal, regional, and education rate, which sits at 0.722889 percent for 2026. On a home assessed at $822,671, the city’s own average, that works out to $5,947 a year. The rate changes annually, so the exact number always depends on the current budget cycle.
What Is Markham Property Tax?
Every homeowner in Markham pays this tax once a year, split across two instalments through their mortgage lender or four instalments if paid directly to the city. It isn’t a flat fee. It’s tied to your property’s assessed value, not your purchase price, which trips up a lot of new buyers who assume the two numbers match.
The Municipal Property Assessment Corporation, or MPAC, sets that assessed value for every property in Ontario. The City of Markham then applies its rate on top. Three separate bodies share the revenue: the City of Markham, the Region of York, and the Province of Ontario through the education portion. That’s why the total figure shifts slightly each year, based on three separate budgets rather than one.
Markham also sends out two separate bills instead of one lump-sum notice. The interim bill in January is really just a placeholder, set at half of what you paid the previous year so the city has cash flow while the new budget gets finalized. The final bill in June is where the real number shows up, once council, the region, and the province have all confirmed their portions. Homeowners who only look at the January number and assume that’s the full year’s cost are usually in for a mild surprise come summer.
How Is Markham Property Tax Calculated?
The formula is straightforward: assessed value multiplied by the total rate equals your annual bill. For 2026, the breakdown looks like this.
- City of Markham portion: 0.177477 percent
- Region of York portion: 0.392412 percent
- Education portion: 0.153000 percent
- Combined total: 0.722889 percent
So a $700,000 assessed home pays roughly $5,060 a year. A $1.1 million home lands closer to $7,952. We’ve seen homeowners budget based on their purchase price instead of their MPAC number, and the surprise on the first bill is real, especially in a hot resale year when the two figures drift apart.
How Much Is the Average Markham Property Tax Bill?
The average current value assessment across Markham in 2026 sits at $822,671, producing a total bill of $5,947. Here’s where that money actually lands:
- Region of York: 54.28 percent, roughly $3,228
- City of Markham: 24.55 percent, roughly $1,460
- Education: 21.17 percent, roughly $1,259
Most residents assume the city keeps the bulk of what they pay. It doesn’t. Just over half goes to York Region for policing, paramedics, transit, and water infrastructure, and that split rarely gets explained on the bill itself.
How Does Markham Property Tax Compare to Other GTA Cities?
Markham has held one of the lowest average rate increases in the Greater Toronto Area for roughly two decades, according to the city’s own budget documents. For 2026, its confirmed residential rate of 0.722889 percent sits below Toronto’s official rate of 0.767311 percent, which includes Toronto’s City Building Fund levy.
That said, a lower rate doesn’t automatically mean a smaller check. Toronto’s average assessed values run higher in many neighbourhoods, so its bigger rate can still land on a smaller number, and vice versa in Markham. Comparing percentages alone is a common mistake; the dollar figure on your notice is the only number that matters for your household budget.
Part of the reason Markham keeps its residential rate low is a strong commercial and industrial base. Business parks and head offices generate their own tax revenue at a separate, higher rate, which takes pressure off homeowners. The effect is more pronounced here than in most neighbouring municipalities, largely because of the commercial growth along the Highway 7 corridor.
When Are Property Tax Bills Due in Markham?
Markham issues two bills every year. The interim bill arrives in January, calculated at fifty percent of the prior year’s total. The final bill follows in June once the city, region, and province have all locked in their budgets.
For 2026, residential final installments are due July 6 and August 5. Homeowners enrolled in the city’s pre-authorized payment plan can spread payments across four, six, or eleven withdrawals instead, which is what most first-time owners choose once they see how the lump-sum dates collide with other summer expenses.
What Happens If You Pay Your Tax Bill Late in Markham?
The penalty structure is set under Ontario’s Municipal Act, and neither city council nor staff can waive it. A missed instalment gets an immediate one percent penalty. Then, on the first of every following month the balance sits unpaid, another 1.25 percent gets added.
That compounds faster than most people expect. A $2,000 instalment left unpaid for three months adds roughly $95 in penalties alone. Automatic withdrawals through the pre-authorized plan remove that risk entirely.
Can You Lower Your Markham Property Tax Bill?
You can’t negotiate the rate itself, but the assessed value underneath it isn’t fixed in stone.
Filing an MPAC Reconsideration
If your property record lists the wrong square footage, an extra bathroom that doesn’t exist, or a finished basement that’s actually unfinished, you can file a free Request for Reconsideration directly with MPAC. There’s a deadline printed on your assessment notice, so this only works if you act before it passes. A correction doesn’t change your current bill, but it lowers the base for future years.
Rebate and Deferral Programs
Markham and York Region also run relief programs for specific situations: registered charities, certain heritage-designated properties, farmland, and low-income seniors or homeowners with disabilities, who may qualify for a deferral rather than a rebate. Eligibility rules shift periodically, so confirming current terms directly with the city’s tax office beats relying on secondhand figures.
FAQ
How do I calculate my Markham property tax?
Multiply your MPAC assessed value by 0.00722889, the 2026 combined rate. A $900,000 home comes to roughly $6,506 a year, before any supplementary adjustments.
Why did I get a supplementary tax bill after buying my house?
New buyers often get billed initially at the previous owner’s assessed value. Once MPAC updates the record to reflect the completed sale or a new build, Markham issues a supplementary bill covering the gap, sometimes a few thousand dollars in year one.
Do seniors get a discount on property tax in Markham?
There’s no automatic senior discount, but low-income seniors and homeowners with disabilities may qualify for a tax deferral through York Region. You need to apply; it isn’t applied automatically to your account.
Can I pay Markham property tax monthly?
Yes, through the pre-authorized tax payment plan, which offers four, six, or eleven withdrawal schedules depending on how you’d rather divide the annual total.
Rates, due dates, and rebate criteria are set fresh every year by three levels of government, so the numbers above reflect the current 2026 cycle. Homeowners planning ahead should check the city’s published rate table each January rather than assume last year’s figure still applies.
