Where H4X Sits — and What That Changes at the Till

H4X sits about 9 km southwest of Montreal, the nearest centre of any size, and is the only postal area our data records for Montréal-Ouest. Its closest postal neighbours are H4B (Montréal) about 1 km off and H4W (Côte Saint-Luc) about 2 km off.

The nearest postal area we hold in another province is K6A (Hawkesbury, Ontario), about 75 km from H4X. A $500 order delivered into H4X carries $74.88 in GST + QST; the same order delivered into K6A carries $65.00 in HST — $9.88 apart on one invoice. Because Canadian sales tax follows the customer, a seller in Montréal-Ouest shipping to both charges 14.975% on the first and 13% on the second, from the same warehouse on the same day.

H4X is suburban ground serving about 5,000 across 3 communities — the settlement pattern where delivered goods matter most. A parcel addressed into H4X 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 — H4X 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 H4X 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 H4X; 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 H4X's page, where the calculator above is already locked to 14.975%.

Selling into H4X: 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 H4X 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.
