• prior to May 1 following the coming into force of the assessment roll

Grounds for adjustment

Your application must briefly explain the grounds or arguments made in support of the adjustment, such as:

• Defects of the building (breakage, construction defects, etc.)
• Nuisances (noise, pollution, flooding, etc.)
• Financial situation (loss of rent, high expenses, sale of comparable buildings)

Before requesting an adjustment of the assessment roll, we recommend that you check the sale prices of comparable buildings in your neighbourhood.

The amount of taxes paid or the comparison of values on the roll (not to be confused with the sale prices for comparable properties) are not considered valid grounds.

If a difference of opinion persists after your application for adjustment is processed, you may lodge an appeal with the immovable property division of the Tribunal administratif du Québec within 60 days.
