Sales Tax for J6K — Châteauguay

What Postal Code J6K Covers

J6K covers western Châteauguay, a residential sector developed mostly after the 1960s, with shops and services along boulevard d'Anjou. The town adjoins the Mohawk territory of Kahnawake, which gives the area a distinctive tax context: sales made on reserve to First Nations members fall under separate rules from those applying elsewhere in Quebec.

Where J6K Sits — and What That Changes at the Till

The centroid of J6K falls roughly 25 km southwest of Montreal, and the code shares its delivery city with 1 other postal area. Its closest postal neighbours are J6J (Châteauguay) about 3 km off and J6R (Mercier) about 5 km off.

The nearest postal area we hold in another province is K0C (Alexandria, Ontario), about 65 km from J6K. A $500 order delivered into J6K carries $74.88 in GST + QST; the same order delivered into K0C carries $65.00 in HST — $9.88 apart on one invoice. Because Canadian sales tax follows the customer, a seller in Châteauguay shipping to both charges 14.975% on the first and 13% on the second, from the same warehouse on the same day.

J6K sits roughly 40 km from the Canada–US boundary, close enough that cross-border buying is part of the local picture. What comes back is a customs question rather than a provincial one, and the thresholds are unforgiving: no personal exemption at all on a same-day trip, CAD 200 once you have been away 24 hours — lose it by a dollar and duty and tax apply to everything you are carrying, not just the excess — and CAD 800 after 48 hours, where only the amount over the line is assessed. The CBSA collects the 5% GST at the booth; Quebec's 9.975% QST on goods brought in for personal use is settled under the province's own rules.

J6K is suburban ground serving about 25,000 across 3 communities — the settlement pattern where delivered goods matter most. A parcel addressed into J6K carries Quebec's 14.975% even when the seller is registered in Alberta and charges 5% to every customer at home.

The 14.975% above is set for the whole of Quebec and does not move between postal codes — J6K pays exactly what every other Quebec code pays. The bill that does move is an overnight one. Quebec's 3.5% tax on lodging applies on top of GST + QST, so a $200 room night inside J6K carries $7.00 of it. Charged on the price of the overnight stay only — the value of breakfast, parking and other services bundled with the room is excluded from the base. It runs out at 32 nights: once the same guest has stayed that long continuously the booking stops being transient accommodation, and the levy stops with it.

Everything above is particular to J6K; the rules that are not — registration thresholds, filing frequency, input tax credit recovery, point-of-sale rebates — are set for the whole of Quebec, and they live on the Quebec sales tax guide rather than being restated on J6K's page, where the calculator above is already locked to 14.975%.

Selling into J6K: What You Need to Register For

Quebec runs a GST + QST system administered by Revenu Québec (both GST and QST), with a registration threshold of $30,000 (GST/QST) ($30,000 (GST/QST via Revenu Québec) for remote sellers). Filing frequency, input tax credit recovery, point-of-sale rebates and the full registration walkthrough are set out on the Quebec sales tax guide — they are province-wide rules, identical for every postal code here, so this page links them rather than repeating them.

1. Charge the rate the address decides. A delivery into J6K is a Quebec sale, so charge 14.975% (5% GST + 9.975% provincial tax) — your own address does not enter into it.
2. Show it the way Revenu Québec (both GST and QST) expects. GST and QST as separate line items — Revenu Québec requires the breakdown on every Quebec invoice.

Everything else about selling here — thresholds, filing frequency, ITC recovery, point-of-sale rebates, and the full province-by-province sourcing rules — is identical for every postal code in Quebec and is set out once on the Quebec sales tax guide and in the Quebec GST/HST calculator.
