Alberta property tax is what you pay each year to your municipality based on your property’s assessed value multiplied by a mill rate, with the bill covering both local municipal services and a provincial education levy. Assessment notices go out early in the year, tax bills follow in late spring, and payment is due at the end of June in most municipalities. Miss that deadline and penalties start immediately.
How the Bill Is Calculated
Two numbers produce your tax bill: your property’s assessed value and the mill rate your municipality sets for the year. Assessed value reflects what your property would reasonably sell for on the open market between a willing buyer and a willing seller, measured as of July 1 of the prior year so every property in the municipality is judged against the same market snapshot.1Government of Alberta. Guide to Property Assessment and Taxation in Alberta
The mill rate is expressed as tax per $1,000 of assessed value. A home assessed at $400,000 with a combined mill rate of 10 owes $4,000 for the year. Municipal councils pass a new tax rate bylaw each year under the Municipal Government Act to match their approved budgets, so the rate can shift annually even if your assessment stays flat.2Open Government. Municipal Government Act
One note on property type: most residential and commercial property is assessed at market value, but farmland is assessed on its agricultural use value rather than what a developer might pay. If actively farmed land shows up on your notice at market value, that’s a valid reason to file a complaint.
The Education Portion
A slice of every Alberta property tax bill funds the public education system. Municipalities collect the levy on the province’s behalf and send it to the Alberta School Foundation Fund, which pools the money and distributes it to school boards based on enrolment.3Government of Alberta. Education Property Tax The province sets the education mill rate annually and applies it province-wide, while the municipal rate varies by jurisdiction. Your bill separates the two so you can see exactly how your payment is split.
What Your Assessment Notice Says — and Why to Check It
Municipalities mail assessment notices between January and April depending on the jurisdiction. The notice is not a bill. It shows the assessed value that will later be multiplied by the mill rates to produce your tax charge.4City of Chestermere. Assessments Your actual bill arrives separately, typically in May.
Read the property details carefully when the notice arrives. Errors in square footage, bedroom count, basement finish, or condition can inflate the assessed value and inflate what you owe. Catching a mistake matters because the complaint clock starts on the notice date printed on the document, not the day you open the envelope. The specific complaint deadline for your property appears on the notice itself.
How to Pay
Most Alberta municipalities offer the Tax Installment Payment Plan, known as TIPP, which spreads your annual bill across 12 monthly withdrawals from your bank account.5Rocky View County. Tax Installment Payment Plan You can join at any time during the year if your taxes are current and not already collected by your mortgage lender.6City of Calgary. Join TIPP (Tax Instalment Payment Plan) Joining mid-year spreads the remaining balance across the months left; the following year resets to 12 equal payments. There are no extra fees, and the plan renews automatically.
Other options: online banking, in person at the municipal office, or a mailed cheque. Many homeowners have their lender collect property tax as part of the monthly mortgage payment and remit it to the municipality on the due date. Credit card payments run through third-party processors and carry a convenience fee around 2.5% of the transaction. On a $4,000 bill, that’s an extra $100.
What Happens If You Pay Late
Due dates and penalty structures vary by municipality, and the penalties are consistently steep. Edmonton’s deadline is June 30. A 5% penalty applies to any unpaid balance on July 1, another 5% on September 1, and a third 5% on November 1, totalling 15% within the year.7City of Edmonton. Penalties and Service Charges Calgary is heavier at the front: 7% on July 1 and another 7% on October 1.8City of Calgary. Late Payments and Penalties
Balances that roll into the following year become arrears and keep accruing. Edmonton adds 1.25% per month on prior-year arrears, compounding to 15% annually.7City of Edmonton. Penalties and Service Charges Calgary charges 1% per month on arrears after December 31.8City of Calgary. Late Payments and Penalties These penalties apply automatically and are not negotiable.
Unpaid taxes eventually put the property itself at risk. Under the Municipal Government Act, once taxes remain unpaid past December 31 of the year they were imposed they become arrears, and once a property has been in arrears more than a year the municipality must place it on a tax arrears list by March 31 and register a tax recovery notification on title at the Alberta Land Titles Office.9Government of Alberta. A Guide to Tax Recovery in Alberta The property is then advertised in the Alberta Gazette and local newspapers, and can be sold at public auction between April 1 and March 31 of the following year.10Regional Municipality of Wood Buffalo.

Appealing Your Assessment
If your assessed value looks too high or the property details on the notice are wrong, you can file a complaint with your municipality’s Assessment Review Board.11Government of Alberta. Municipal Property Assessment – Complaints and Appeals Complaints about residential properties with three or fewer dwelling units and about farmland go to the Local Assessment Review Board; properties with four or more dwelling units and non-residential property go to the Composite Assessment Review Board.
The deadline is strict: 60 days from the assessment notice date printed on your notice.12Government of Alberta. Assessment Complaint Dates for 2026 Miss the window and you lose the right to challenge that year’s valuation. Each municipality sets its own filing fee, shown on the assessment notice, and the fee is refunded if the board rules in your favour.13Strathcona County. Assessment Review Board – Complaints
Winning a complaint takes evidence that your valuation doesn’t match comparable properties. Recent sale prices of similar homes are the strongest kind. If three houses on your street with the same layout sold for $380,000 and yours is assessed at $430,000, the gap tells a clear story. Photographs of deferred maintenance, structural problems, or other conditions that reduce value also help. At the hearing you present your case and the municipal assessor presents theirs. If the board agrees your assessment is too high, it can lower the value, which directly reduces your tax bill for the year.
The Seniors Property Tax Deferral Program
Alberta’s Seniors Property Tax Deferral Program lets eligible homeowners defer all or part of their residential property taxes, including the education portion, through a low-interest loan from the provincial government.14Alberta.ca. Seniors Property Tax Deferral Program To qualify you must:
- Be 65 or older (only one spouse or partner needs to meet the age requirement)
- Own a residential property in Alberta that is your primary residence
- Have at least 25% equity in the home
If approved, the province pays your property taxes directly to your municipality. The loan is secured against your home equity, and repayment isn’t required until you sell, the home stops being your primary residence, or you’re no longer a registered owner.14Alberta.ca. Seniors Property Tax Deferral Program
The interest rate is currently 4.45%, reviewed in April and October by the Minister of Assisted Living and Social Services together with the Minister of Treasury Board and Finance, and set with reference to the prime rate at the time of review.15Alberta.ca. Seniors Property Tax Deferral Program – Loan Estimator Only simple interest is charged, calculated on the original loan balance each year rather than the growing total. You can also repay the loan voluntarily at any time without penalty.
Property That Is Exempt
Not all Alberta property is taxable. The Municipal Government Act exempts several categories entirely:
- Land and buildings owned by the federal or provincial government, or by a municipality
- Property owned by school boards, universities, colleges, and technical institutes when used for educational purposes
- Property owned or leased by a religious body and used primarily for divine service, public worship, or religious education
- Hospitals and nursing homes receiving financial assistance from the Crown and used for health care purposes
- Land and buildings used for burial purposes
- Property owned or leased by a library board under the Libraries Act
These exemptions turn on how the property is used, not just who owns it. A building owned by a religious organization but leased to a commercial tenant would not qualify. If your property appears on the assessment roll and you believe it should be exempt, the assessment complaint process is the way to raise it, using the same 60-day deadline.12Government of Alberta.
