How to appeal your property assessment in Alberta

In Alberta, your municipality assesses your home at its market value on July 1 of the previous year. In Calgary, notices arrive in January and you have a 67-day review period to talk to an assessor and, if needed, file a complaint with the Assessment Review Board; the fee for a home with three or fewer dwellings is $50, refunded if you win.

Tips

Compare your assessment with recent sales near July 1 of last year and with similar homes' assessments; Calgary and Edmonton publish neighbourhood assessment data.
Lenders don't use your assessment for a refinance; for borrowing, see the equity calculator.

Evidence wins appeals: sales of similar homes near the valuation date, similar homes' assessments, and corrections to the facts on your notice.
