Use this Ottawa property tax calculator to estimate your annual and monthly property tax from your MPAC assessed value and the current City of Ottawa rate. Property tax is one of the highest ongoing costs of owning a home, yet it’s often overlooked until the first bill arrives. Whether you’re budgeting the true monthly cost of a move-up home or comparing carrying costs between neighbourhoods, this tool gives you a fast, clear estimate — and the sections below explain exactly how the number is built.

How property tax is calculated in Ottawa
Your property tax is simply your assessed value multiplied by the tax rate for your property class. Two inputs drive it: the value MPAC has assigned to your home, and the rate the City of Ottawa sets each year.
Your MPAC assessed value (based on the 2016 valuation date)
The Municipal Property Assessment Corporation (MPAC) assesses every property in Ontario. Importantly, current assessments still reflect the January 1, 2016 valuation date — Ontario’s province-wide reassessment has been postponed. That’s why your assessed value is usually lower than today’s market price, and why a home’s assessment doesn’t jump the moment it sells for more. You can find your assessed value on your tax bill or through MPAC’s AboutMyProperty portal.
The City of Ottawa tax rate
Each year, City Council sets the tax rate as part of the municipal budget. Your total rate combines the municipal levy (city services), a provincially set education levy, and, in urban areas, a transit levy. Because the rate is set annually, always use the current-year figure — update the rate field in the calculator to match.
Urban vs. rural property tax in Ottawa
Ottawa is geographically huge, spanning dense urban cores and large rural areas like Carp, Dunrobin, Greely and Constance Bay. Rural properties generally pay a reduced transit levy (or none), because they don’t receive the same level of transit service — so the effective rate on a rural home can be lower than on an equivalent urban one. If you’re comparing an urban home to a rural one, set the calculator’s rate to each area’s class to compare like with like.

Top-tier service — you just keep thousands more when your home sells. Smart sellers are already making the switch. Your home deserves the best, and your wallet deserves a break.
What property tax means for your monthly carrying cost
Lenders count property tax in your monthly housing costs when they qualify you, and it’s a permanent line in your budget for as long as you own. On a typical Ottawa home, it can add several hundred dollars a month. Factoring it in early — alongside your mortgage, insurance and any condo fees — is the difference between a budget that holds and one that surprises you. This is exactly the kind of number a move-coordinator approach nails down before you commit.

Get Cash Back When You Buy a Home in Ottawa
Can you get cash back when buying a home in Ottawa? Yes. Jason Polonski, a Chairman's Club REALTOR® serving Ottawa and Kanata, shares part of his commission with buyers — up to $3,000 cash back at closing.* You still get full-service, award-winning representation: expert pricing, sharp negotiation, and hands-on guidance from first showing to keys in hand. No cut corners and no rebate-only shortcuts — just real money back in your pocket when you buy your Ottawa or Kanata home.
Property tax when you buy or sell
Property tax is settled between the buyer and seller on the closing statement of adjustments. If the seller has prepaid taxes past the closing date, the buyer reimburses them for the buyer’s share; if taxes are owing, the seller credits the buyer. It’s usually a modest adjustment, but it’s real cash, and your lawyer handles it. New owners should also set up a payment method with the City (or a pre-authorized plan) so nothing lapses after possession.
How to lower or appeal your assessment
If you believe your MPAC-assessed value is too high — for example, it’s out of line with comparable homes — you can ask MPAC to review it through a Request for Reconsideration and, if needed, appeal to the Assessment Review Board. Start by comparing your assessment to similar properties through MPAC’s portal. Because assessments are based on the 2016 valuation date, comparisons are against that baseline, not current prices.

Property tax equals your MPAC assessed value multiplied by the City of Ottawa tax rate for your property class. The rate is set each year in the municipal budget and combines municipal, education and (in urban areas) transit levies.
It’s set annually by City Council and varies by property class and whether you’re in an urban or rural area. Use the current-year rate from the City of Ottawa in the calculator for an accurate estimate.
Because it’s based on each home’s MPAC-assessed value. Two similar-looking homes can have different assessments based on size, lot, condition and features — and rural vs. urban properties pay different transit levies.
No. Assessments currently reflect the January 1, 2016 valuation date, so buying above the assessed value doesn’t immediately raise your assessment. Your tax is based on the assessed value, not your purchase price.
Often, yes — rural properties generally pay a reduced or no transit levy, which can lower the effective rate compared with an equivalent urban home.
Yes. You can file a Request for Reconsideration with MPAC and, if needed, appeal to the Assessment Review Board. Compare your assessment to similar properties first through MPAC’s portal.
