Preparing for Alberta's 2026 property reassessment

Updated: August 05, 2025

The province of Alberta is conducting a property reassessment, evaluating properties based on their market value as of July 1, 2025. Ensuring your property is assessed accurately will help you plan for potential changes in your property tax obligation and avoid the risk of overpaying.

In Alberta, property assessment is primarily the responsibility of the municipalities. Prepared annually and mailed out early in the year, property occupants across the province of Alberta should be aware of the following time frames in anticipation of their property assessment notices:

booking confirmation
Pre-roll consultation period
Property owners participating in the pre-roll consultation (September to November) have a limited opportunity to review and discuss their updated assessments with city staff before the roll is finalized.
report
New property assessment notices
Property assessment notices are generally mailed out to property occupants in January. These notices inform you of the assessed value of your property, which is used to calculate property taxes.
clock
Customer review period
The review period, typically from January to March, is a critical time for property occupants to carefully examine their new property assessment for accuracy.
alert
Complaint filing deadline
If you believe that your property has been inaccurately assessed, you have the right to file a complaint. The deadline for filing a complaint is usually within 60 days from the date the notice was mailed, typically around mid-March.

Property assessment processes and timelines can vary across different municipalities. For detailed information regarding the assessment process, deadlines, or any specific inquiries about your municipality, please contact our office directly.

Each year, each respective assessing authority reassesses all properties within its boundaries. This process is known as an annual assessment cycle, aimed at ensuring property assessments accurately reflect the current conditions in the real estate market as of a specified valuation date.

Your total annual property tax liability is determined by multiplying your property's assessed value by the tax rate in your jurisdiction.

If you are an industrial or commercial property occupant, or a multi-residential property owner, it is important to ensure that your property is assessed accurately.

Don't wait until you receive your tax bill to discover an overassessment. Overvalued assessments are common and can result in higher property taxes, which can lead to an inflated bottom line, impacting cash flow and profitability.
