Welcome Tax Calculator Mirabel 2026

A notice that now settles in two steps

Stretched across nearly five hundred square kilometres of seven historic sectors — Saint-Janvier, Saint-Augustin, Saint-Canut, Saint-Benoît, Saint-Hermas, Sainte-Scholastique and the Domaine-Vert area — Mirabel is the largest North Shore municipality and one of the most polynuclear cities in the Laurentides. Its welcome tax, however, runs on an unusual calendar: since 1 January 2025, the City's Taxation, évaluation et mutation page confirms that the duty on transfers of immovables can be settled in two instalments once the amount owed crosses an administrative floor set by the Treasury. The first instalment falls due thirty days after the invoice is issued, the second sixty days after the first instalment's due date. The calculator above helps you line that up with your liquidity in the weeks following the notary's signature.

A single-family market still gaining ground

According to Centris real-estate statistics for Mirabel, on the four trailing quarters through the first quarter of 2026, the median single-family price sits at $619,500 (up 5% year over year) on 545 sales, with an average 30 days on the market — fifteen days faster than the comparable period a year earlier. Condominiums trade at a $429,737 median (up 1%) on 292 sales; the two-to-five-unit plex climbs to a $810,000 median (up 16%) on 94 transactions. With 939 residential sales over the trailing year and dollar volume close to $578 million, Mirabel remains one of the Laurentides' market engines, fuelled by a population that jumped 21% between 2016 and 2021. The market value that feeds the welcome-tax taxable base follows the same trajectory whenever a typical Mirabel single-family home changes hands.

What moves the amount, and Mirabel's place on the North Shore

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 property assessment roll multiplied by the comparative factor set each year by the City. External firm LBP Évaluateurs agréés, mandated by Mirabel, has just filed the new 2026-2027-2028 triennial roll, and consultation sessions at the Domaine-Vert Nord Cultural Centre were offered to owners who wanted to question the assessors directly. On the grid side, by-law no. 2455 added a top municipal bracket that lines Mirabel up with neighbours Sainte-Thérèse and Lorraine: a clean jump from the intermediate step to the top bracket, with no transitional step. By contrast, Boisbriand inserts a transitional step that softens the curve before its highest rate, and Blainville triggers its top bracket later on the taxable base. Run the calculator above across the four cities for the same property value: the spread shows up mostly above the top-bracket trigger.

Municipal and provincial programs worth knowing

The City runs no direct rebate on the duty itself, but its Subventions page collects several levers worth tapping after closing. New families will find the reusable-diapers grant and the feminine-hygiene products grant, both household-focused. On the land side, the tree-planting incentive, the rain-barrel refund, the home-composter grant and the wildlife-friendly landscaping program support sustainable choices on a new property. 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 triennial 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 Services mail the notice the month following registration of the deed. The first instalment is due thirty days after issue, and the second, when it applies, sixty days after the first instalment's due date. Payment runs through your financial institution (using the eighteen-digit reference number from the remittance coupon), in person at the City Hall counter (cash, cheque or INTERAC debit within the daily authorized limit), or by mail to 14111, rue Saint-Jean. Credit-card payments are not accepted. Past the due dates, annual interest accrues daily on the outstanding amount, and a capped monthly penalty applies. For unusual situations — transfers of immovables not entered in the land register, or an exemption condition that ceases to be satisfied — two disclosure forms are filed with the Treasury Services. Your notary will confirm whether you qualify for the provincial home-access tax credit framed by the same Act.
