Welcome Tax Calculator L'assomption 2026

A 1.08 comparative factor that tilts the taxable base

L'Assomption publishes a comparative factor of 1.08 for 2026, applied to the value entered on the assessment roll to derive the "standardized value." When that figure exceeds the price paid or the consideration stated in the deed, it becomes the base for the welcome-tax notice. The City's real-estate transfer duty page walks through the mechanics; the calculator above gives the working estimate you'll want for closing. The factor is reset each year, so it's worth a fresh look the moment a new notice arrives.

A market sitting just above the top municipal step

According to Centris real-estate statistics for L'Assomption for the fourth quarter of 2025, the single-family median came in at $535,000, up 11% year over year, with homes spending an average of 30 days on the market — 5 days less than a year earlier. On a trailing four-quarter basis, the single-family median was $532,937 (+7%) across 238 transactions. Condominiums, still the minority segment locally, posted a trailing median of $372,722 (+10%), and total residential dollar volume reached $166.9 million (+16%). The takeaway for a buyer: the typical detached home in L'Assomption now lands just above the entry point of the top municipal bracket, which makes the welcome-tax math sensitive to the value the City retains.

What moves the amount, and how L'Assomption stacks up against MRC neighbours

The taxable base is the greater of the price paid, the consideration stated in the notarial deed, or the standardized value (roll value times the comparative factor). Verify the roll value by civic address, account number or cadastre through Accès-Cité, the City's online assessment portal. On the rate-grid side, L'Assomption shares its design with its MRC neighbours — Repentigny and Mascouche — with a clean jump from the intermediate step straight to the top municipal bracket and no transitional step in between. For the same property value, crossing the municipal line within the MRC barely changes the number. The contrast shows up against Boisbriand on the northwestern Couronne nord, whose grid inserts an intermediate step that flattens the curve in the mid-range. Run the calculator above on the same property value across all three cities to see the mechanic materialize side by side.

Municipal programs for new residents

L'Assomption does not run a dedicated welcome-tax rebate, but the Défi 5 000 arbres, anchored in the City's environmental policy, includes two streams that fit the move-in window. The newborn tree program delivers a container tree to families whose child is born on the territory, dropped off directly by the Public Works team. The low-cost noble-tree program lets a new owner add a second tree for $25, delivered with a soil coupon from Jardinerie Villeneuve. Neither is automatically applied to the City's notice: each request goes through its own form once the buyer is settled and ready to landscape.

Payment, timing and the provincial home-access credit

The welcome-tax notice is mailed once the sale is published at the Quebec land register and the Treasury Division has updated the account on the matricule. Payment of the tax account goes through your financial institution using the 18-digit reference number — on Desjardins AccèsD, the biller is listed under « Assomption » or « Ville L'Assomption ». The City also accepts pre-authorized debit, a cheque mailed with the remittance coupon, or a cheque dropped in the after-hours box at the Complexe municipal entrance. The annual property tax account now switches to four instalments when the total reaches $300 or more — a new cadence worth folding into the first-year budget. 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).
