In short · September 28, 2026
In Newfoundland and Labrador, an appeal that works shows the assessment departs from actual value at the base date or is not uniform with similar properties; the key documents are comparable sales around that date, photos and repair quotes (rules verified September 28, 2026).
The two recognized grounds
The MAA sums up the two basic reasons to appeal. In the owner’s opinion:
- the property has been assessed for an amount higher or lower than its actual value;
- “The property was not assessed uniformly with similar properties in similar neighborhoods where the property is located.”
Everything turns on the base date
The Act sets value “as of the base date.” A sale from last year counts for less than a sale close to the base date. In St. John’s, the 2026 and 2027 notices reflect January 1, 2024. On an MAA notice, the base date is printed on the notice.
The MAA also explains that if your property sold around the base date, the assessment will likely be close to the price without having to match it: assessment is mass appraisal, whose primary purpose is that similar properties receive similar assessments.
The St. John’s list, useful everywhere
The City of St. John’s publishes a checklist to prepare for a hearing. It works for an MAA appeal as well.
- Similar sales (size, age, location) that closed around the base date.
- A professional estimate of market value as of the base date.
- Contractor repair estimates for physical issues. The City warns that not every defect affects assessed value.
- Assessments of comparable properties in the neighbourhood, using the Property Assessment Search.
- A point-by-point comparison: location, lot, building size, age, structure type, quality, finished or unfinished basement, garage, outbuildings, repairs, environmental problems.
- Photographs of your property and the comparables, especially if condition or quality is at issue.
- For a condo: floor, unit location, view, parking, elevators and building services.
What the commissioner can and cannot do
The commissioner is not bound by the rules of evidence (s. 35(5)): a hand-made chart is acceptable. Written arguments or telephone participation are possible. In St. John’s, everything must be provided as documents: the City notes you cannot submit hyperlinks.
Two limits matter. The commissioner does not touch taxes: only the assessment. And the commissioner does not amend an assessment only because it is above or below actual value if it bears a just and fair relation to other assessments in the municipality (s. 37(1)). The uniformity argument therefore weighs as much as the value argument.
What does not work
One last point: the Act requires you to let the assessor in and provide requested information; otherwise, the right to appeal falls (s. 47(4)). For a complex file, a report from an AACI or CRA appraiser often makes the difference. See after you appeal and verified appraisers.
- Your tax amount: it depends on the rate set by council, outside the commissioner’s power.
- Today’s market when it differs from the base date.
- Asking prices from listings: only completed sale prices count.
- Late evidence: in St. John’s, a missed disclosure deadline can delay the hearing.

Talk to a professional appraiser in your area
For an income property, a high value or a file headed to the appeal board, a professional appraiser (AACI or CRA, Appraisal Institute of Canada) is the right person.

Frequently asked questions
Which grounds of appeal are recognized?
The MAA names two: an assessment higher or lower than actual value, or an assessment not uniform with similar properties in similar neighbourhoods.
Which sales should I use?
Sales of similar properties that closed around the base date printed on your notice. In St. John’s, the base date for the 2026 and 2027 notices is January 1, 2024.
Can I cite a website as evidence?
Not in St. John’s: the City says hyperlinks cannot be provided and all materials must be given to the commissioner.
Can the commissioner lower my taxes?
No. The commissioner rules only on the assessment. The City of St. John’s states the commissioner has no authority over taxes or taxation levels.
