Welcome Tax Calculator Sainte-Thérèse 2026

A brand-new 2026-2027-2028 triennial roll resets the baseline

At the heart of the MRC de Thérèse-De Blainville, Sainte-Thérèse has just opened a new assessment cycle: the 2026-2027-2028 triennial roll was filed by LBP Évaluateurs agréés using market conditions as of July 1, 2024. Because the 2026 municipal comparative factor stays neutral per the City's Taxes, évaluation et droit de mutation page, the value entered on the roll reads directly as the taxable base used for the welcome tax at closing. The calculator above already combines that base with the municipal bracket grid in force, ahead of the notice the Finance Department mails out in the weeks following publication of the deed at the Quebec land register.

A North Shore market tightening days-on-market

In the first quarter of 2026, Centris real-estate statistics for Sainte-Thérèse record 102 residential sales (up 8% year over year) for $56.17 million in volume (up 13%). The single-family segment posts 41 transactions at a stable $579,000 median, cleared in 23 average days on market — twenty-four days faster than a year ago. Condominiums, especially along boulevard du Séminaire and around the Sainte-Thérèse commuter-rail station, total 43 sales at a $385,000 median (up 9%) in 25 days. Plexes (2 to 5 units) are scarcer, with a $758,312 trailing-four-quarter median (up 17%). The Centris–Statistics Canada community profile puts the population at 26,533 with a density of 2,799 residents per square kilometre — one of the highest north of Laval, a compactness that nudges a typical home in the Village or near the Bois-de-l'Équerre past the City's intermediate threshold.

What moves the amount, and where Sainte-Thérèse sits in the MRC

The taxable base remains the greater of the price paid, the consideration stated in the deed and the market value — the entry on the online property assessment roll multiplied by the year's comparative factor. On the bracket side, Sainte-Thérèse uses the standard four-bracket provincial grid with no transitional municipal step before the top rate — the same profile as immediate neighbours Rosemère and Lorraine. Run the calculator on identical property values and the mechanic is identical in those three municipalities. The comparison gets more interesting with Boisbriand, whose curve is softened by a transitional step before its top rate, and with Blainville, where the top bracket only kicks in much further up the value ladder. The 2026-2027-2028 roll being fresh, this is also the right moment to check your value: a revision request must reach the Finance Department by April 30, 2026.

City programs and services for new residents

Sainte-Thérèse does not refund the welcome tax itself, but its Subventions section groups several post-purchase grants that come in handy for a new household: a reusable diapers and sustainable hygiene products rebate of up to $250 per family, a sewer-backup and flood-protection grant program, and a turnkey front-yard tree-planting program for roughly twenty homes each year. The City also welcomes new residents with an annual fall welcome morning and issues, free of charge, a Carte citoyen valid for two years that opens the parc Richelieu outdoor pool and the parc régional du Domaine Vert. For older buyers, the provincial grant tied to a sharp rise in municipal taxes may offset, under income and ownership conditions, the impact of the brand-new roll. An otherwise exempt transaction still owes the supplementary duty (droit supplétif) framed by the Act respecting duties on transfers of immovables (CQLR, c. D-15.1).

Instalment payment and the provincial home-access credit

Sainte-Thérèse stands out from most of its neighbours by allowing, under by-law 1355 N.S., the welcome-tax bill to be settled in a single instalment or in four instalments spaced forty-five days apart from the previous due date. Payment runs through your financial institution using the eighteen-digit matricule, by cheque made out to Ville de Sainte-Thérèse, or by drop-off in the green mail slot in the City Hall entrance, accessible at any time. The annual municipal tax bill stays separate and is spread over four 2026 due dates (March 6, May 6, July 6 and October 6); you can consult it via the online tax account or the Mon Espace citoyen portal. The supplementary duty owed on otherwise exempt transfers is, by contrast, payable in a single instalment within forty-five days of the account being mailed. Your notary will confirm whether you qualify for the provincial home-access tax credit framed by the same Act.
