Where H4Y Sits — and What That Changes at the Till

The centroid of H4Y falls roughly 15 km west of Montreal, and the code shares its delivery city with 2 other postal areas. Its closest postal neighbours are H9P (Dorval) about 2 km off and H9S (Dorval) about 3 km off.

The nearest postal area we hold in another province is K6A (Hawkesbury, Ontario), about 70 km from H4Y. A $500 order delivered into H4Y 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 Dorval shipping to both charges 14.975% on the first and 13% on the second, from the same warehouse on the same day.

Dorval anchors a mixed code, so spending here runs to fuel, groceries and trades work rather than dense storefront retail. Trades invoices are where GST + QST errors cluster in a code like H4Y: labour and materials are taxed the same way, but only the materials leave the contractor with a recoverable credit. With Montréal–Pierre Elliott Trudeau International Airport inside the code, the tax line runs straight through the terminal: duty-free sales past security sit outside the GST/HST net, while every landside shop and restaurant in the same building sits inside it at 14.975%.

The 14.975% above is set for the whole of Quebec and does not move between postal codes — H4Y 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 H4Y 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 H4Y; 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 H4Y's page, where the calculator above is already locked to 14.975%.

Selling into H4Y: 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 H4Y 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.
