Welcome Tax Calculator Blainville 2026

A threshold that arrives later — and a step with no railing

Blainville pushes the point at which the top municipal welcome-tax rate kicks in noticeably further down the price scale than most of its neighbours in the MRC de Thérèse-De Blainville. For a buyer chasing a bungalow in Domaine de Fontainebleau, a condo in Chambéry or a cottage in the older Notre-Dame quarter, the wrinkle is subtle. For a renovated high-end home, a freshly converted intergenerational house or a well-placed plex near chemin du Plan-Bouchard, the wrinkle shows up clearly on the transfer-duty notice the City mails out about sixty days after the visit to the notary.

A snapshot of the Blainville market

According to Centris real-estate statistics for Blainville for Q4 2025, the median single-family price came in at $697,500 (down 3% year-over-year), with an average time on market of 29 days, down 20 days from the same period a year earlier. Across the last four quarters, the single-family median climbs to $721,875 (up 5%) and the condominium median to $430,675 (up 4%); for two- to five-unit plexes the four-quarter median reaches $759,875 (up 15%). Why it matters here: the single-family median sits just below the threshold at which the City switches to its upper municipal bracket, while the plex median has already crossed it. Depending on the property type, you stay inside the standard portion of the scale or land on the steepest step of the curve.

What moves the amount, and how Blainville compares to nearby cities

As elsewhere in Quebec, the tax base is the highest of three figures: the amount actually paid for the transfer, the consideration listed in the deed, or the uniformized value on the property assessment roll. The current three-year roll was filed by LBP Évaluateurs agréés in late 2024; the uniformized value used for the calculation can sit well above your negotiated price, especially after a sharp reassessment. On the rate side, Blainville pushes its upper municipal threshold meaningfully further than Sainte-Thérèse or Rosemère, both of which flip to the top rate at the standard threshold. Boisbriand, in the other direction, slips an intermediate step into its grid that softens the climb on higher-end homes. Blainville takes the opposite bet: a later threshold, but no intermediate step — once the line is crossed, the rate jumps in one move. Run the calculator above on the same property under each city to see the difference side by side.

The program to open before pulling a permit

This is the municipal lever most useful to a Blainville buyer, and the one most easily missed at the notary's table. The Programme d'aide à la rénovation et à l'agrandissement résidentiel — by-law 1227 — applies to properties at least twenty years old in eligible sectors and, citywide, to any detached single-family home converted into intergenerational housing under article 63 of the zoning by-law 1418. The support comes as a credit that offsets the property tax increase triggered by the post-work reassessment, for the year of the work and the two following years. Conditions to meet: an RBQ-licensed contractor, work that adds at least $3,000 to the assessed value, a municipal permit issued before the start, and the project completed within nine months of permit issuance (or by December 31, 2027 at the latest). Eligible work covers doors and windows, exterior cladding, foundations, structure, plumbing, electrical, heating-ventilation, integrated kitchen or bathroom cabinetry, extensions, or setting up an intergenerational unit. For a buyer planning to redo the envelope or add a unit in the first year, the credit can absorb a meaningful share of the tax jump that follows reassessment.

Payment, timing and the provincial home-access credit

Once the sale is recorded at the land register, the Service des finances prepares the official notice and mails it about 60 days after registration with the notary. It is payable in a single instalment by the due date printed on the bill. Payment can be made online through the Transphere payment portal or your Voilà citizen account, at your financial institution (counter, ATM, online banking, or telephone banking, using the eighteen-digit reference number on the notice), or by mail with a cheque payable to Ville de Blainville. Note that payment is not accepted at the city hall reception counter. On the provincial side, your notary will confirm whether you qualify for the home-access tax credit, which can refund part of the duties paid by eligible first-time buyers. The underlying rule remains the Act respecting duties on transfers of immovables (CQLR, c. D-15.1).
