Every year, Calgary condo owners open an envelope — or these days, an inbox — containing a number that can feel surprisingly large for a home where you don't even own the land underneath. Property tax is one of the biggest annual costs of condo ownership, and for 2026 there are some real changes worth understanding. Here is the full picture: how the tax is calculated, what a typical condo actually pays, the key dates to remember, and what to do if your assessment looks wrong.
How Calgary calculates your condo property tax
Strip away the jargon and the formula is simple: your assessed value multiplied by the combined residential tax rate. For 2026, Calgary's combined residential rate is 0.61803%. Another way to say it: roughly $6.18 of tax for every $1,000 of your condo's assessed value.
The word “combined” does a lot of work here, because your bill is really two taxes printed on one page. The municipal portion funds city services — police, fire, transit, parks, snow clearing, and road maintenance. The provincial education portion goes to the Alberta government and funds the school system. Both are levied on the same assessed value, then added together into the single total you see on your bill.
One thing that catches first-time buyers off guard: the rate doesn't change with the style of your home. A downtown high-rise unit, a suburban townhouse, and a detached house all use the same combined residential rate. What makes your bill different from your neighbour's is the assessed value of your specific unit — its size, floor, finishes, building, and location.
A worked example: the $450,000 condo
Let's run the numbers on a $450,000 condo — a realistic figure for a two-bedroom unit in many Calgary neighbourhoods this year.
Step one: start with the assessed value, $450,000. Step two: multiply by the 2026 combined residential rate of 0.61803%, or 0.0061803 as a decimal. Step three: $450,000 × 0.0061803 = $2,781.14.
So the annual property tax on a $450,000 condo comes to about $2,781 — roughly $232 a month. If you budget monthly, set that $232 beside your mortgage payment, condo fees, insurance, and utilities to see your true cost of ownership. It adds up fast, and plenty of buyers forget to include it until the first bill arrives.
Two caveats. First, this is an estimate: your actual bill is driven by your official assessed value, which the city sets each year — not by what you paid for the unit or what a listing site says it is worth today. Second, the rate can shift from year to year as council and the province set their budgets, so treat this as a 2026 snapshot.
What the City of Calgary says a typical condo pays
For context, the City of Calgary publishes its own illustration every budget season. For 2026, the city's example shows a typical condo — assessed at $347,000 — paying about $1,347 in property tax for the year.
The reason that number is lower than our $450,000 example is straightforward: the assessed value is lower, and assessed value is the entire basis of the calculation. The $347,000 figure is the typical (median) condo assessment for 2026. Notably, it slipped from the previous year's median of $359,000 — condo assessments softened slightly even as other parts of the market moved differently.
The practical takeaway: if your unit is assessed near the city-wide median, your bill should land in the neighbourhood of the city's example. Own a larger unit, a top-floor suite, or a unit in a premium concrete tower, and your assessed value — and your bill — will run proportionally higher.
What changed in 2026
Two forces moved the 2026 bill, and they tell very different stories.
On the city side, the increase was modest. The municipal portion of a typical residential bill rose by about $49 — roughly 1.8%. Council kept its own revenue ask relatively restrained.
The bigger story is the provincial education portion. The province's take jumped by about $338 on a typical bill, an increase of roughly 21%. That single change means the province now collects close to 40% of every property tax dollar, leaving about 60% with the city.
This is why so many condo owners will see a larger total even though the median condo assessment actually fell. When assessments dip but the tax requirement climbs — especially the provincial share — the math still points upward. If your 2026 bill is higher than last year's despite a flat or lower assessment, the provincial education increase is almost certainly the explanation.
Assessments: your 2026 tax is based on July 1, 2025
Here is a quirk of the system that confuses owners every year: your 2026 property tax is not based on what your condo is worth in 2026. It is based on its market value as of July 1, 2025 — the legislated valuation date. Assessors examine sales and market conditions as of that single day, then set the values that drive the following year's taxes.
Assessment notices were mailed on January 14, 2026. That notice deserves your full attention: it lists your assessed value, the property details the city has on file, and the deadline for filing a complaint if you believe the number is wrong. If you never received one, look it up on the city's assessment website well before the complaint window closes.
For condos, the 2026 roll tells a clear story. The median assessed condo value landed at $347,000, down from $359,000 the year before — a softening of roughly 3%. Apartment-style and townhouse units each have their own medians, but the direction was consistent: condo assessments eased across the board while the tax rates moved the other way.
Key dates for the 2026 tax year
Mark these on your calendar:
- January 14, 2026 — 2026 assessment notices mailed.
- Late May 2026 — property tax bills mailed.
- June 30, 2026 — property taxes due in full.
- July 1, 2026 — a 7% penalty is added to any unpaid balance.
- October 1, 2026 — a second 7% penalty is added to whatever remains unpaid.
The penalties are the part to respect. Miss the June 30 deadline and a 7% charge lands on July 1; still unpaid by October, and another 7% is applied to the remaining balance. If June cash flow is tight, arranging payment ahead of the deadline is far cheaper than absorbing back-to-back penalties.
Condo fees and property taxes are not the same thing
This is the mix-up I hear most from first-time condo buyers: the idea that monthly condo fees somehow cover, reduce, or replace property tax. They do not — not by a dollar.
Your property tax goes to the City of Calgary and the provincial government. Your condo fees go to your condo corporation: the legal entity that insures the building, maintains hallways, elevators, the roof, and the parkade, looks after landscaping and snow removal, and builds the reserve fund for major future repairs. The two streams never cross. A building with high fees gets no tax discount, and a low-fee building pays the same tax formula as everyone else.
Where they do meet is in your budget. When you're comparing buildings, always look at taxes and fees together: a unit with modest fees but a high assessment can cost more per month than a higher-fee unit with a lower assessment. If you're actively shopping, browse today's Calgary condos for sale and run both numbers on any unit you're serious about before you fall for the floor plan.
How to check — and challenge — your assessment
Don't just accept the number on your notice. Start by verifying the basics: unit size, floor level, parking, and any special features the city has on record. Errors happen, and a wrongly recorded detail can inflate your value.
Next, compare. Look up your property on the city's online assessment search and stack your value against similar units — ideally identical floor plans in your own building or complex. If a matching unit two floors down is assessed $20,000 lower with no obvious reason, you have the makings of a case.
A REALTOR® can also pull a comparative market analysis showing what truly comparable units have sold for around the valuation date, which is exactly the evidence assessors and review boards find persuasive.
If something looks off, call the city's assessment office first — plenty of files get corrected informally once an assessor takes a second look. If you can't resolve it there, you can file a formal complaint with the Assessment Review Board. The deadline is printed on your assessment notice and it is firm: miss it, and you live with the number for the year.
One honest caveat before you appeal: the process challenges your assessed value, not the tax rate and not the size of your bill. A successful appeal trims the value side of the formula, which lowers your tax — but it won't change the 0.61803% rate or the province's share.

Frequently asked questions
Do my condo fees reduce my property tax?
No. Condo fees go to your condo corporation for building operations, maintenance, insurance, and the reserve fund. Property tax goes to the city and the province. They are completely separate, and paying higher fees does not lower your tax bill.
Why did my tax bill go up if my condo's assessed value went down?
Because your bill is assessed value multiplied by the tax rate — and in 2026 the rate side did the work. The median condo assessment slipped to $347,000 from $359,000, but the provincial education portion jumped about 21% (roughly $338 on a typical bill) and the city portion rose about 1.8% (roughly $49). Higher rates on a slightly lower value still produced a bigger bill.
When are 2026 Calgary property taxes due?
Bills are mailed in late May 2026 and payment is due in full on June 30, 2026. Unpaid balances attract a 7% penalty on July 1 and a further 7% penalty on October 1.
How do I appeal my 2026 condo assessment?
Start with the assessment notice mailed January 14, 2026: confirm the property details, then compare your value with similar units in your building. Raise concerns with the city's assessment office first, and if needed file a formal complaint with the Assessment Review Board before the deadline printed on your notice.
