Welcome Tax Calculator McMasterville 2026

A new triennial roll that reshapes the buyer's base

Wedged between Beloeil and Mont-Saint-Hilaire on the west bank of the Richelieu, McMasterville covers barely four square kilometres — one of the most compact municipalities in MRC de la Vallée-du-Richelieu. Its land-tax base, however, has just absorbed an unusual jolt: the City's Taxes et évaluation page confirms that the 2025-2026-2027 assessment roll was filed by the firm mandated by the MRC, with a sharp overall increase in taxable land value and a comparable jump on the residential side. The direct consequence for a buyer: the roll value, which acts as a floor in the taxable base of the duty on transfers of immovables, is markedly higher for the next three years. The calculator above bakes in that new floor so you can plan the notice that arrives thirty days after closing.

A single-family market accelerating on a tight footprint

According to Centris real-estate statistics for McMasterville, on the four trailing quarters through the first quarter of 2026, the median single-family price sits at $552,875 (up 3% year over year) on 35 sales, with an average 16 days on the market — ten days faster than the comparable period a year earlier. The total residential segment posts 59 transactions (up 31%) for just over $33 million in dollar volume (up 46%). On a footprint that hosts fewer than 6,000 residents per the Statistics Canada community profile, the pace pushes roll values upward right as the new roll takes effect. The taxable base of a typical McMasterville single-family home has just crossed the entry point of the standard provincial grid's top municipal bracket, after sitting below it under the previous roll.

What moves the amount, and where McMasterville sits inside the MRC

The taxable base is the greater of the price paid, the consideration stated in the deed and the market value — the entry on the online assessment roll multiplied by the year's comparative factor set by the City. Searches are free and run by civic address, cadastre or matricule on PG Solutions' Immonet portal. On the grid side, McMasterville lines up with its immediate neighbour Mont-Saint-Hilaire, tied to it by the rail bridge across the Richelieu, and with other municipalities of MRC de la Vallée-du-Richelieu: a clean jump from the intermediate step to the top municipal bracket, with no transitional step. By contrast, Otterburn Park, further south in the same MRC, inserts several transitional steps that soften the curve before its highest rate. Run the calculator across the three cities for the same property value: the spread shows up mostly in the upper tier — exactly where a typical McMasterville home now lands.

Municipal and provincial programs worth knowing

The City runs no direct rebate on the duty itself, but several levers can ease the post-purchase budget. The City's intergenerational dwelling program offers, under conditions, a partial refund of certain municipal charges when the home includes an intergenerational unit properly authorized by the Urbanism and Sustainable Development Services. For new families, the « Un nouvel enfant, un arbre! » program delivers a tree free of charge, dropped off at home by the Public Works team. The financial assistance for reusable diapers and sustainable personal hygiene products covers part of the eligible spending for residents. For older buyers, the provincial grant tied to a sharp rise in municipal taxes can offset, under income and length-of-ownership conditions, the bump triggered by the new roll. A transaction otherwise exempt still owes the supplementary duty (droit supplétif) set out in the Act respecting duties on transfers of immovables (CQLR, c. D-15.1).

Payment, timing and the provincial home-access credit

Once the sale is published at the Quebec land register, the Treasury and Finance Services prepare the notice and mail it. In McMasterville, the welcome-tax bill is settled in a single instalment within thirty days of the invoice being issued; it cannot be split, unlike the annual tax bill, which spreads over four due dates. Payment runs through your financial institution (online, ABM, counter or telephone) using the nineteen-digit matricule as reference, by cheque made out to Ville de McMasterville (mailed in or dropped in the outside mail slot at the main entrance of City Hall), or in person at the counter, which accepts cash, cheques and INTERAC debit. Credit-card payments are not accepted. The City reminds buyers that no new tax account is issued at the time of a transfer: it is the new owner's responsibility to confirm that outstanding municipal taxes have been settled, or face annual interest plus a capped monthly penalty. Your notary will confirm whether you qualify for the provincial home-access tax credit framed by the same Act.
