Markham Keeps Barely a Quarter of Your Bill

Three bodies, three rates, one bill. Shown on Markham's own average assessment of $822,671.

That total of $5,947 is Markham's own published average residential bill, and it is what makes this breakdown checkable: $822,671 × 0.722889% reproduces it exactly. Note what the shares say — the Region of York takes 54.3%, more than double Markham's own 24.6%. When people complain to the city about their tax bill, roughly three quarters of it was set by someone else.

Two different rates are published for Markham. This is the right one.

If you look this up yourself you may find 0.700278% rather than 0.722889%. Markham's FAQ page gives the first; its tax brochure gives the second. They cannot both be right, and the city's own average bill settles it.

$822,671 × 0.722889% = $5,947  ← matches the published average bill
$822,671 × 0.700278% = $5,761  ← does not

This calculator uses 0.722889%. It is also the figure that reconciles against the Region of York's separately published upper-tier rate and the province-wide education rate, which is the second reason to prefer it. Your own tax bill is always the final authority — if it disagrees with this page, the bill wins and we would like to hear about it.

The lowest rate in Ontario is not the lowest bill

At 0.722889%, Markham has the lowest residential rate of any Ontario municipality whose 2026 figure can be verified from an official document — below even Toronto. Windsor charges 2.096514%, roughly 2.90 times as much.

That is a fact about the assessment base, not about generosity. A municipality sets its rate to raise the budget it needs from the property values it has; high values mean the same revenue arrives at a lower rate. Markham's assessments are among the highest in the province, so the rate is low and the dollars are not. Comparing cities is only meaningful at the same assessed value, which is what this table does.

Every rate read from the issuing municipality's own published schedule. Municipalities whose 2026 rate could not be verified are excluded rather than estimated — see the multi-city calculator for the wider list and its caveats.

Watch York Region, not Markham, for increases

The Region of York portion rose from 0.375863% to 0.392412% for 2026 — about 4.4% on that component. Because York is the biggest single line, a regional increase moves your bill more than the same percentage increase in Markham's own rate would.

Two councils set budgets each spring and either can change what you pay. A headline about Markham holding its own levy flat does not mean your bill is flat, because roughly 54% of it is a regional decision and another 21% is a provincial one.

Your assessment, meanwhile, is frozen. MPAC still values on a January 1, 2016 date and reassessment has been postponed repeatedly, so a rising market does not raise your tax by itself — only a larger budget does. Enter the figure from your assessment notice, never a recent sale price, or this calculator will overstate your bill substantially. Our Ontario property tax guide covers the two-tier system and how to appeal an assessment.
