Where H3Z Sits — and What That Changes at the Till

The centroid of H3Z falls roughly 4 km southwest of Montreal, and the code shares its delivery city with 1 other postal area. Its closest postal neighbours are H3Y (Westmount) about 1 km off and H4C (Montreal) about 1 km off.

The nearest postal area we hold in another province is K6A (Hawkesbury, Ontario), about 80 km from H3Z. A $500 order delivered into H3Z 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 Westmount shipping to both charges 14.975% on the first and 13% on the second, from the same warehouse on the same day.

H3Z is dense urban ground — 4 named neighbourhoods inside one postal area, about 10,000 — and density changes the taxable mix rather than the rate. Prepared food, personal services and in-person retail dominate what is rung through Westmount codes like this one, all of it at 14.975%, while the zero-rated grocery basics that anchor a suburban shop are a smaller share of the total than the province-wide averages suggest.

The 14.975% above is set for the whole of Quebec and does not move between postal codes — H3Z 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 H3Z 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 H3Z; 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 H3Z's page, where the calculator above is already locked to 14.975%.

Selling into H3Z: 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 H3Z 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.
