Welcome Tax Calculator Chambly 2026

A South Shore market that's repricing upward

According to Centris real-estate statistics for Chambly for the fourth quarter of 2025, the single-family median came in at $630,000, up 5% year-over-year, with homes spending an average of just 18 days on market — 21 days less than a year earlier. On a trailing four-quarter basis, the single-family median was $640,875 (+10%), while condominiums — a segment gaining traction around the Bassin and the Vieux-Chambly waterfront — settled at $398,250 (+13%). Total residential volume in dollars grew 11% over the trailing year, even as Q4 transaction count slipped 15%. The takeaway for a buyer: the typical detached home now clears the top municipal threshold by a wider margin than before, and that's the slice of the price that does most of the heavy lifting on the welcome-tax notice.

A fresh triennial roll for 2026-2028

The triennial assessment roll for 2026-2027-2028 was filed in September 2025 by LBP évaluateurs agréés, following the inventory maintenance completed in July 2025. In plain English, the value entered on the roll — the value that feeds the taxable base of your welcome-tax notice — has just been refreshed across the entire Chambly territory. Because the taxable base is the higher of the price paid or the market value (roll value times the comparative factor set in the City's annual taxation by-law), that refresh flows straight into the portion that lands in the top municipal bracket on closing.

What moves the amount, and how Chambly stacks up against nearby cities

You can verify the roll value for any address through the public assessment roll operated on the ImmoNet platform. On the rate-grid side, Chambly shares its design with Mont-Saint-Hilaire, a neighbour in MRC La Vallée-du-Richelieu: a clean jump straight to the top municipal bracket at the standard threshold, with no intermediate step. By contrast, Otterburn Park — just across the Richelieu — layers in several intermediate steps before reaching the highest rate, which softens the curve for buyers landing in the middle range. For the same detached home near the Fort de Chambly or in the Chambly-Ouest sector, it's the abrupt step into the top bracket that opens the gap with Otterburn Park; against Mont-Saint-Hilaire, the gap shows up almost entirely through the roll value, since the brackets line up. Run the calculator above on the same property value under Chambly, Mont-Saint-Hilaire and Otterburn Park to see the mechanic materialize side by side.

Municipal programs for new residents

If your home appears on the City's revised heritage building inventory, the heritage architecture advisory program entitles you to up to eight hours of professional services with the firm Ateliers Beaupré Michaud, reimbursed by the City. That's particularly useful around Vieux-Chambly, along avenue Bourgogne or near the canal, where renovation pressure is highest. The environmental rebate for cloth diapers, reusable feminine hygiene products and reusable absorbent underwear is administered by the non-profit Aux sources du bassin de Chambly at 50% of the amount paid (minimum $50, maximum $100 per product line). The home EV charging station is subsidized by the City at 25% of purchase and installation cost, up to $250, and Quebec's Roulez vert program adds a provincial subsidy on the charger itself. None of these programs is applied automatically to the welcome-tax notice.

Payment, timing and the provincial home-access credit

The welcome-tax notice is mailed once the sale is published at the Quebec land register. Payment goes through your financial institution using the 18-digit account number (no dashes) as the reference and selecting the supplier 'Ville de Chambly-Taxes', by cheque made out to the City, by credit card through the Voilà! portal with a 1.98% service fee, or in person at the temporary collection counter at the Centre administratif et communautaire (56 rue Martel), which also accepts cash and debit card. A drop box near the main entrance at 56 rue Martel lets you leave an envelope after hours. Late payment triggers interest at 10% per year, plus a 0.5% penalty per full month of delay (capped at 5% per year). Your notary will confirm whether you qualify for the provincial home-access tax credit, governed by the Act respecting duties on transfers of immovables (CQLR, c. D-15.1).
