In Alberta, property assessments are updated every year from scratch — the value from the previous year is not reused.

How Assessments Work:

• Assessments are based on sales data from the past 12 to 36 months (usually 3 years).
• The valuation is set as of July 1 of the previous year.
• Only sales information available before the cut-off dates is used, which can cause year-to-year changes.

Step 1: Land Value (As if Vacant)

• The land is assessed as if it were empty, without considering any buildings.
• Land is grouped into categories like Residential or Industrial/Commercial, based on the "Highest and Best Use," meaning:
  • The use must be legal.
  • Physically possible.
  • Financially feasible.
  • Return the highest value.

Step 2: Improvements (Buildings)

• For properties with buildings ("improved properties"), the value of the outbuildings and residence is added.
• Outbuildings (E.g. Garages, sheds, etc.) are valued based on cost manuals (Alberta's 2021 Manual or Marshall & Swift).
• Residences are valued by comparing local real estate sales ("market comparison").

Example Calculation:

Land Value + Garage/Shed Cost + Residence Value = Total Assessed Value

Important Notes:

• Values are adjusted based on market trends (example: if it costs $200/sq ft to build but market value is $250/sq ft, an adjustment is made).
• Assessments are done in groups (mass appraisal), and adjustments are made using the median value for fairness.

All assessments follow Alberta legislation and standardized procedures to ensure accuracy, fairness, and transparency and must pass a government audit.

In Alberta, mass appraisal is the method used to determine property assessments — especially when valuing thousands of properties at once.

Instead of evaluating each home individually like a real estate appraiser might do, mass appraisal looks at groups of similar properties together and applies consistent standards across the group.

Key points about mass appraisal:

• Group-Based Approach: Properties are grouped based on similar characteristics like location, size, age, quality of construction, and type of use (e.g., residential, commercial, industrial).
• Market Trends: The Assessment Department studies recent real estate sales (from the last 12–36 months) to see what properties are selling for in the market.
• Statistical Analysis: Mathematical models are used to find patterns in sale prices. These models help estimate a typical market value for properties that share similar features.
• Adjustment Factors: Factors such as building condition, size, upgrades, or neighbourhood desirability are taken into account by applying adjustments. For example, newer homes might have a slightly higher value adjustment compared to older homes.
• Median Value: To ensure fairness, the department uses the median (middle) adjustment from a group of properties. This means extreme high or low sale prices don’t unfairly impact the value for everyone.
• Base Year and Cost Manuals: The province provides standard cost guidelines (like the 2021 Alberta Residential Cost Manual), and adjustments are made to reflect the current real estate market as of July 1 each year.

Mass appraisal is used for:

• Efficiency: It would be impossible to individually appraise thousands of properties every year.
• Consistency: It ensures that similar properties are assessed in a uniform and fair way.
• Legally Required: Mass appraisal is mandated under Alberta’s Municipal Government Act to create property assessments that are equitable and based on market value.

1. Review Your Assessment Notice
Carefully examine the details on your property assessment notice. Ensure that all information is accurate, including:

• Property description
• Assessed value
• Property classification
• Ownership details

If you find discrepancies or believe the assessed value is incorrect, you have the right to file a complaint.

2. Contact the County
Before filing a formal complaint, it's advisable to contact our Assessment department. Engaging in a discussion with an assessor can often resolve misunderstandings or errors without the need for a formal appeal.

3. File a Formal Complaint
If discussions with the assessor do not resolve your concerns, you can proceed with a formal complaint:

• Complete the Assessment Review Board Complaint Form: Provide detailed information about the alleged inaccuracies.
• Submit the Complaint: Send your completed form to the County.
• Pay the Filing Fee: fee is required when filing a complaint.

Residential properties with three or fewer dwellings: Approximately $50

Non-residential properties: Up to $150

4. Prepare for the Hearing

Once your complaint is accepted, a hearing will be scheduled. To present a strong case:

• Gather Evidence: Collect documents such as recent comparable property sales, photographs, and any other relevant information that supports your claim.
• Submit Evidence Timely: Ensure all evidence is submitted within the deadlines specified by your municipality.
• Understand the Process: Familiarize yourself with the hearing procedures to effectively present your case.

5. Attend the Hearing

During the hearing:

• Present Your Case: Clearly explain the inaccuracies and present your supporting evidence.
• Be Concise: Stick to the facts and avoid introducing new issues not previously disclosed.
• Listen to the Assessor: Understand the assessor's perspective and be prepared to address their points.

6. Await the Decision

After the hearing, the Assessment Review Board will deliberate and issue a decision. If the decision is in your favor, your assessment will be adjusted accordingly. Any overpaid taxes will be refunded or credited to your account.

7. Further Appeals

If you disagree with the Assessment Review Board's decision, you may appeal to the Court of King's Bench of Alberta. However, appeals are limited to questions of law or jurisdiction, not disagreements over the assessment's accuracy. You must file an application for "Judicial Review" within 30 days of receiving the decision.

Under Alberta legislation, all property is presumed to be assessable and taxable unless it qualifies for a specific exemption. This principle ensures fairness and consistency in how municipalities fund services such as roads, police, fire protection, waste management, and education.

The rules for determining assessability and taxability are set out in the Municipal Government Act (MGA) and supporting regulations.

1. What Is an Assessable Property?A property is considered assessable under Alberta’s Municipal Government Act if it includes any of the following:
   • Land – Includes all surface land and rights related to it.
   • Improvements – This refers to buildings, structures, and fixtures located on the land. According to Alberta legislation, improvements are assessable whether they are permanently affixed to the land or simply attached by their own weight.
   Other assessable property types:
   • Machinery and equipment used in manufacturing, oil and gas, or industrial operations not including tractors, combines, grain trucks etc.
   • Linear property such as pipelines, power transmission lines, and cable systems
   Unless a property qualifies for a statutory exemption, it is presumed to be assessable and will be assigned a value for property taxation purposes.
2. What Is a Taxable Property?A property is taxable if it has been assessed and does not meet the criteria for exemption.Common exempt properties include:
   • Government-owned land (e.g., municipal, provincial, or federal)
   • Schools, hospitals, and places of worship
   • Properties used by non-profit organizations, depending on use
   • Cemeteries and Indigenous reserve lands
   Important: Just because a property is owned by a non-profit or government agency does not automatically exempt it—usage and legal ownership both matter, and specific legislative conditions must be met.

4. Property Assessment Classes in AlbertaAll properties are classified for taxation purposes. Each class may have a different tax rate:
   • Class 1: Residential
   • Class 2: Non-residential (commercial/industrial)
   • Class 3: Farmland
   • Class 4: Machinery and Equipment
   Your property's assessment class affects the municipal and provincial tax rates applied.

Farm status refers to land that is actively used for farming operations, such as growing crops, raising livestock, or producing other agricultural products. This is defined under section 2(1)(f) of the Regulation (Matters Relating to Assessment and Taxation Regulation, 2018) and includes:

• Horticulture, apiculture (beekeeping), aquaculture
• Raising livestock like cattle, pigs, or goats
• Timber production with a woodland management plan

To qualify, the property must be used for agricultural production, and owners may be required to provide evidence of farm-related income to the County.

If your property has farm status:

• It is assessed at agricultural use value, which is typically lower than market value.

Example: A non-farm rural parcel might be assessed at $500,000 (market value), while a farm parcel might be assessed at $20,000 (agricultural value), significantly reducing property tax.

2. Exemption for Farm Buildings

Under Section 30 of the Regulation, farm buildings are fully exempt from property tax across Alberta starting in 2022. This includes:

"Any farm building in a city, town, village or summer village... to the extent of 100% of its assessment"
— Matters Relating to Assessment and Taxation Regulation, 2018, Section 30(f)

Farm buildings are defined in Section 2(1)(e) as improvements (structures) used for farming, excluding residences.
