Property tax in Calgary is calculated by multiplying your property’s city-assessed market value by a combined tax rate made up of a municipal portion set by City Council and an education portion set by the Government of Alberta. For the 2026 tax year, a typical single-family home assessed at the median value of $706,000 saw the municipal portion rise about $49 and the provincial education portion rise about $338 over the prior year.1The City of Calgary. Understanding Your Residential Property Tax Changes 2026 Bills are mailed in May and due by the last business day of June.
How Your Bill Is Calculated
Two separate rates apply to the same assessed value, and they are set by two different governments.
- The municipal portion funds Calgary’s operating and capital budgets, including roads, fire, police, parks, and transit. City Council sets it each year. For 2026 it increased 1.8% over the previous year.1The City of Calgary. Understanding Your Residential Property Tax Changes 2026
- The provincial education portion funds Alberta’s public school system. Every municipality collects it on the province’s behalf, and the City of Calgary does not control the rate. For 2026 it rose 21%.2Alberta.ca. Education Property Tax1The City of Calgary. Understanding Your Residential Property Tax Changes 2026
That split explains why a bill can jump sharply in a year city spending barely moved. The city’s online calculator shows both portions separately so you can see where the change is coming from.3The City of Calgary. Property Tax Calculator
How Your Property Is Assessed
The dollar figure driving your bill is the assessed market value: what the city estimates your property would sell for between a willing buyer and willing seller. Calgary values every property as of July 1 of the previous year, and evaluates physical condition as of December 31.4The City of Calgary. Market Value Assessment For the 2026 tax year, that means the market on July 1, 2025, and the physical state of your home on December 31, 2025.
Location, lot size, building age, total living area, and any renovations all factor in. Assessment notices are mailed in January, several months before the tax bill in May.5The City of Calgary. Property Assessment and Tax You can also pull up to five years of past notices through the city’s eNotice portal.6The City of Calgary. Request a Property Tax Bill or Assessment Notice
Supplementary Assessments for New Work
If you build an addition, finish a basement, or complete new construction during the tax year, the city may issue a supplementary assessment covering the improvement. The supplementary bill is prorated: the improvement’s assessed value is multiplied by the applicable tax rate, divided by 12, and then multiplied by the number of months the improvement was complete or occupied.7The City of Calgary. Supplementary Tax Bills You pay only for the portion of the year the upgrade existed.
Why the Bill Can Rise Even When the Assessment Drops
Property tax is based on relative value across the city, not your assessment in isolation. If most Calgary homes went up 10% and yours went up 3%, your share of the total burden actually fell. If your assessment stays flat while others drop, your share grows. The calculator breaks out the assessment change and the budget-driven rate change side by side so you can see which one moved your bill.3The City of Calgary. Property Tax Calculator
When and How to Pay
Bills are mailed in May and the full amount is due by the last business day of June. For 2026 that is June 30.8The City of Calgary. Late Payments and Penalties The penalty applies to any account with an unpaid balance after the deadline whether or not the paper bill reached you.
The Monthly Plan (TIPP)
Instead of one June payment, you can enroll in the Tax Instalment Payment Plan and have 12 monthly amounts withdrawn from your bank account on the first of each month.9The City of Calgary. Manage Your TIPP Account You can sign up at any point in the year. The monthly amount is reviewed twice a year to stay aligned with your actual annual tax, so you don’t drift significantly over or under.10The City of Calgary. TIPP (Tax Instalment Payment Plan) Being enrolled means the June late penalty cannot apply to you.
Other Ways to Pay
If you’d rather pay on your own schedule, the city accepts online and phone banking (add “Calgary Property Tax” as a payee using the nine-digit roll number from your bill), payment at your bank, in-person payment at the Tax Advisory Services counter on the third floor of the Calgary Municipal Building (cash, cheque, and debit only), and payment by mail with a cheque or money order payable to “The City of Calgary.”11The City of Calgary. Property Tax Payment Options Credit cards are not accepted directly by the city. If your mortgage lender collects principal, interest, and taxes together, property tax is handled through that.
What Happens If You Pay Late
Penalties stack on a set schedule:8The City of Calgary. Late Payments and Penalties
- July 1: 7% is added to any unpaid current-year taxes.
- October 1: Another 7% is added to whatever is still outstanding.
- After December 31: The balance becomes tax arrears, and 1% is added on the first of every month going forward.
An owner who ignores the bill entirely through the end of the year faces a combined 14% penalty before the monthly charges even begin. On a $4,000 bill, that’s $560 within six months.
Prolonged non-payment goes further. Once taxes have been in arrears for more than one year, the city registers a tax recovery notification on your land title. If the arrears still are not paid, the property can be placed on an arrears list and ultimately sold at public auction to recover the unpaid taxes.12The City of Calgary. Real Estate Public Auction Paying the full arrears before the auction removes the notification. The process is governed by Part 10 of Alberta’s Municipal Government Act.
Appealing Your Assessment
If the assessed value on your January notice looks wrong, you have 67 days from the mailing date to act. That window is called the Customer Review Period, and during it you can contact a city assessor to discuss your concerns informally.13The City of Calgary. Customer Review Period Many disputes are settled here without a formal complaint.
If informal discussion doesn’t resolve it, you can file a complaint with the Calgary Assessment Review Board, an independent quasi-judicial body established under the Municipal Government Act.14Calgary Assessment Review Board. Calgary Assessment Review Board – Legislation and Case Law The board hears evidence from you and from the city’s assessors and can order an adjustment if the assessment does not reflect market value or fairness.15The City of Calgary. A Guide to Filing an ARB Complaint The complaint must be filed within the 67-day review period.
Filing fees depend on property type:16Calgary Assessment Review Board. Calgary Assessment Review Board – File a Complaint
- Residential with three or fewer dwellings, and farmland: $50, reduced to $40 if the complaint is received before January 31. A residential condominium counts as a single residential property.
- Residential with four or more dwellings, and non-residential: $650.
- Local improvement complaint: $20.
The fee is refunded if the appeal succeeds or if you settle with the city’s Assessment and Tax department before the hearing.
If You Can’t Afford the Bill
Two programs help, and they target different situations.
Property Tax Assistance Program
This city program offers a credit toward the tax increase for residential owners in financial hardship, at any age.17The City of Calgary. Property Tax Assistance Program Eligibility runs through Fair Entry, which uses Statistics Canada’s Low Income Cut-Off to set thresholds; a single-person household currently qualifies with total income at or below $31,906, and a four-person household at $59,288.18The City of Calgary. Should I Apply? You provide income proof for every adult in the household, and you apply through Fair Entry rather than the tax department.
Seniors Property Tax Deferral Program
This provincial program lets homeowners 65 or older defer all or part of their residential property taxes, including the education portion, through a low-interest home equity loan from the Government of Alberta.19Alberta.ca. Seniors Property Tax Deferral Program Only one spouse or partner needs to be 65, and there is no income test. The province registers a caveat on your land title to secure the loan. You can repay any time, but the balance comes due when you sell, are no longer a registered owner, or the property is no longer your primary residence.
