Can I contest my Quebec assessment in the second or third year of the roll?

Generally no — the review window is the roll's first year, before May 1. Mid-roll reviews are possible only in specific situations, such as when the assessor alters the roll or an event materially changes the property. If you missed the window, note the deadline for the next roll deposit; it comes around every three years.

Is Quebec's welcome tax part of my property taxes?

No. The droits de mutation — the welcome tax — is a one-time land transfer duty billed by the municipality after you buy, calculated on brackets of the price or assessment. Your annual property tax and school tax bills are separate, recurring obligations. All three use the assessment roll, which is the only thing they share.

Property taxes in Quebec

Quebec taxes property on triennial rolls: your municipality's assessor deposits a new roll every three years, valued as of roughly eighteen months before the roll takes effect, and that value stands for all three years unless the property changes. If you disagree, the window to file an application for review closes before May 1 of the roll's first year. Two things Quebecers often fold into 'property tax' are actually separate: the school tax arrives as its own bill, and the 'welcome tax' (droits de mutation) is a one-time transfer duty paid when you buy, not an annual tax.

Life of each municipal assessment roll: 3 years
Review deadline in a new roll's first year: Before May 1
Gap between valuation date and the roll taking effect: ~18 months

How Quebec's triennial roll and review process work

Each municipality (or its regional county municipality) deposits a new three-year roll on a staggered schedule — Montreal's current roll covers 2026–2028 — with values reflecting the market as of July 1 of the second year before the roll begins. Your value then holds for three years, which cuts both ways: a hot market won't touch your taxes mid-roll, and a correction won't lower them either. The main chance to contest is the roll's first year, by filing an application for review with the municipal body before May 1 (with an extension to 60 days from mailing if your notice arrived after the end of February). There's a filing fee that scales with the property's value; if the review fails, the escalation is to the Tribunal administratif du Québec.

Budget your closing costs with the vocabulary straight: the annual municipal tax bill (with its own instalment dates), the separate annual school tax bill, and — once, at purchase — the droits de mutation immobilière, universally nicknamed the welcome tax, which municipalities bill a few months after closing. Buyers who plan for the first two and forget the third get an unwelcome surprise in the mail.
