Welcome Tax Calculator Rosemère 2026

A new triennial roll that has shifted the taxable base in Rosemère

The 2024-2025-2026 assessment roll, filed on October 25, 2023 by LBP Évaluateurs agréés and laid out on the City's Rôle d'évaluation page, opened a wide gap between residential growth and a much flatter commercial sector. The practical takeaway for a buyer: the standardized value of a typical single-family home now sits well above the entry point of the standard provincial grid's top municipal bracket, and that is the figure the calculator above runs on. The useful habit is the same one as in every Quebec city: build the estimate before the notice arrives in the mail rather than after.

A single-family market that sets the pace

According to Centris real-estate statistics for Rosemère for the first quarter of 2026, the median single-family price stands at $830,888 (up 13% year over year) on 35 transactions, with an average 48 days on the market; on the most recent four trailing quarters, the single-family median climbs to $849,909 (+16%) on 164 sales. Condominium and plex volumes are too thin to produce a reliable statistic — Rosemère is, in practice, an almost entirely detached single-family market. For a typical home, the taxable base lands inside the top municipal bracket of the grid in most cases, and the steep step at that threshold weighs on the welcome-tax bill from the first median-priced transaction onward.

What moves the amount, and where Rosemère stands inside the MRC

The taxable base is the greater of the amount supplied for the transfer, the consideration stated in the deed, or the market value — the roll entry multiplied by the year's comparative factor. Verify the roll entry on the City's Rôle d'évaluation page or directly inside the Voilà! citizen account. On the grid side, Rosemère sticks to the standard provincial design, like Lorraine and Sainte-Thérèse: a clean jump from the intermediate step to the top municipal bracket, with no transitional step. By contrast, Blainville pushes the trigger of its top bracket noticeably further up the taxable base, and Boisbriand inserts a transitional step that softens the curve before its own top tier. For the same property value, the spread shows up mostly in the upper tier — exactly where a typical Rosemère home already lands. Run the calculator above across the four cities to see where your transaction falls.

Municipal grants: no rebate, but targeted family aid

The City runs no welcome-tax rebate, no home-access program and no revitalization program. The Programmes de subventions page lists family and environmental grants instead — up to $150 per child for a cloth-diaper set, and $150 toward a tree planted on the property to mark a birth — with forms emailed to loisirs@ville.rosemere.qc.ca for the diaper grant or to permis.inspections@ville.rosemere.qc.ca for the newborn tree, on proof of purchase, residence and, where relevant, birth. The Une naissance, un livre program runs through the municipal library for infants registered before their first birthday. For a senior buyer whose roll entry has jumped sharply, the provincial grant for seniors to offset a municipal tax increase applies directly on the annual tax account.

Payment, timing and supplementary duty

Once the sale is published at the Quebec land register, the Service des finances et trésorerie prepares the notice and mails it. In Rosemère, the welcome tax is paid in a single instalment within thirty days of the billing date — the multi-instalment schedule used for the annual property tax account does not apply here. Payment then runs through your financial institution's website (using the eighteen-digit reference number that follows the SIPC 488 code on the coupon), through the Voilà! online services platform, by cheque made out to Ville de Rosemère — mailed or dropped at the counter — or in person at 100 rue Charbonneau (cash, cheque, debit). Confirm the outstanding balance with reception at extension 0, and any instalment-schedule question at extension 1222. A transaction that is exempt from the duty still owes the supplementary duty (droit supplétif) set out in the Act respecting duties on transfers of immovables (CQLR, c. D-15.1): your notary confirms the applicable exemption and the amount entered in the deed, and will also confirm whether you qualify for the provincial home-access tax credit framed by the same Act.
