Welcome Tax Calculator Lorraine 2026

Six square kilometres of planned residential fabric, and a grid that bites quickly

On barely six square kilometres of almost exclusively residential fabric in the Basses-Laurentides, Lorraine is an unusual case inside the MRC Thérèse-De Blainville: the typical home now sits well above the entry point of the standard provincial grid's top municipal bracket. The City's taxation page also flags that the welcome-tax notice is payable in a single instalment within thirty days of the billing date — the four-instalment schedule used for the annual property tax account does not apply. The calculator above gives the working estimate to set aside cash before the notice arrives in the mail.

A single-product market that drives the bill

According to Centris real-estate statistics for Lorraine for the first quarter of 2026, the median single-family price sits at $770,750 (up 13% year over year) on 30 transactions, with an average 62 days on the market; on the most recent four trailing quarters, the single-family median climbs to $792,062 (+9%) on 118 sales. For condominiums and plexes, transaction volumes are too thin to produce a reliable statistic — almost every sale here is a detached single-family home. The practical takeaway: the taxable base of a typical Lorraine home already sits well above the entry point of the top municipal bracket, and the steep step at that threshold weighs on the welcome-tax bill from the very first median-priced sale.

What moves the amount, and where Lorraine 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 entry on the 2025-2026-2027 triennial roll through Immonet; it was deposited in November 2024 by LBP Évaluateurs agréés, as set out on the City's Évaluation municipale page. On the grid side, Lorraine sticks to the standard provincial design, like Rosemère 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. Run the calculator above across the four cities for the same property value: the spread shows up mostly in the upper tier — exactly where a typical Lorraine home already lands.

Municipal grants and provincial programs worth knowing

The City runs no welcome-tax rebate, no home-access program and no revitalization program. The Subventions page lists eco-responsibility grants instead — rainwater barrel, home composter, eco-friendly lawn-care equipment and a few others — open to Lorraine residents on proof of purchase within one hundred and eighty days of the transaction. For a buyer taking over an older home still heated by oil, the City points to the federal Oil to Heat Pump Affordability Program and to the provincial Chauffez vert program. A senior buyer whose roll value has jumped sharply can also check eligibility for the provincial grant for seniors to offset a municipal tax increase, which appears directly on the annual tax account. 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 to enter in the deed.

Payment, timing and the provincial home-access credit

Once the sale is published at the Quebec land register, the Service des finances et trésorerie prepares the notice and mails it. Payment then runs through your financial institution's website (using the eighteen-digit matricule as reference), through a cheque made out to Ville de Lorraine — mailed or dropped in the outside slot at 33 boulevard De Gaulle — or in person at the collection counter, which accepts only INTERAC debit and cheque (no credit card). The City issues no receipt, so the owner takes care of passing the statement to the mortgage lender. Late payment triggers annual interest charges and a monthly penalty on the outstanding balance. Your notary will then confirm whether you qualify for the provincial home-access tax credit framed by the same Act.
