Each new assessment roll triggers the same wave of reactions. My house went up 30%? I’ll sell it at that price! Then comes the cold shower, or the opposite. Municipal assessment and market value are two different measures, calculated for different reasons, and confusing them is costly. The property assessment roll is a tax tool governed by Quebec law, not a selling price. Here’s why, and how to read each one correctly.<\/p>\n

Two measures, two objectives<\/h2>\n

The municipal assessment is used to distribute taxes among property owners. It is produced by the municipality, in bulk, based on a sample of comparable properties. Market value, on the other hand, is the most probable price at which your home would sell today, on an open market. The former is stable for three years; the latter moves with supply and demand. One looks backward, the other looks at the present.<\/p>\n

The table below summarizes the differences that matter.<\/p>\n

The 18-Month Gap That Changes Everything<\/h2>\n

Here is the detail that few property owners know. The values listed in the triennial roll reflect the market as of July 1st, approximately 18 months before it comes into effect. Concrete example: in Montreal, the 2026-2027-2028 roll came into effect on January 1, 2026, with an average increase of 12.2%, but calculated based on the market of July 1, 2024. Eighteen months, in a moving market, translates into tens of thousands of dollars in difference from today’s reality. Using this figure to list your home is like selling with the rearview mirror.<\/p>\n

So What Is the Municipal Roll For?<\/h2>\n

To anticipate your taxes, quite simply. It is also useful for understanding the tax distribution in your neighborhood. If you believe your assessment is significantly too high, you can request a review, but within strict deadlines and with solid evidence. To establish a selling price, however, only one approach holds up: analyzing recent comparable sales in your area. This is exactly what a free property evaluation by a local real estate broker provides.<\/p>\n
