Where G3A Sits — and What That Changes at the Till

G3A sits about 20 km west of Quebec City, the nearest centre of any size, and is the only postal area our data records for Saint-Augustin-de-Desmaures. Its closest postal neighbours are G1Y (Quebec City) about 9 km off and G2E (L'Ancienne-Lorette) about 9 km off.

The nearest ground where the rate changes is about 230 km away — E7A in New Brunswick, at 15%. That distance is the useful part: nothing bought or delivered in G3A is a borderline case, so the only rate question worth asking here is whether the sale is taxable at all, not which province's number applies to it.

G3A is suburban ground serving about 20,000 across 3 communities — the settlement pattern where delivered goods matter most. A parcel addressed into G3A carries Quebec's 14.975% even when the seller is registered in Alberta and charges 5% to every customer at home. Autoroute Félix-Leclerc runs through the code, and highway trade has its own rules: freight moving between provinces is a zero-rated interlining supply in the carrier's hands, while the fuel, meals and repairs bought along the way carry G3A's 14.975% like any other local purchase.

The 14.975% above is set for the whole of Quebec and does not move between postal codes — G3A 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 G3A 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 G3A; 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 G3A's page, where the calculator above is already locked to 14.975%.

Selling into G3A: 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 G3A 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.
