About Quebec Sales Tax

Quebec has a 14.975% combined sales tax rate, consisting of the 5% federal GST and 9.975% provincial QST.

Quebec uses a dual tax system where the 5% federal GST and 9.975% Quebec Sales Tax (QST) are calculated separately on the purchase price. Both taxes are administered by Revenu Québec. Unlike other PST provinces, the QST is recoverable as an Input Tax Refund (ITR) for registered businesses. Remote sellers must register once they exceed $30,000 in Quebec sales.

What Postal Code G6G Covers

G6G serves Thetford Mines, the main town of the Les Appalaches region, built around what were once the world's largest asbestos mines. The amalgamated city includes the former towns of Black Lake and Robertsonville, ringed by mine tailings and open pits. Its mining and mineralogy museum documents that industrial heritage.

Where G6G Sits — and What That Changes at the Till

The centroid of G6G falls roughly 50 km west of Saint-Georges, and the code shares its delivery city with 1 other postal area. Its closest postal neighbours are G6H (Thetford Mines) immediately alongside and G0N (Disraeli / East Broughton) about 25 km off.

The nearest ground where the rate changes is about 250 km away — E7A in New Brunswick, at 15%. That distance is the useful part: nothing bought or delivered in G6G 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.

G6G is dense urban ground — 4 named neighbourhoods inside one postal area, about 26,000 — and density changes the taxable mix rather than the rate. Prepared food, personal services and in-person retail dominate what is rung through Thetford Mines 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 — G6G 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 G6G 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 G6G; 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 G6G's page, where the calculator above is already locked to 14.975%.

Selling into G6G: 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 G6G 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.

Frequently asked questions

Quick answers to the most common questions users ask.

What areas does postal code G6G cover?

The Forward Sortation Area G6G covers Thetford Mines, Black Lake, Robertsonville and Pontbriand in the Chaudière-Appalaches (Les Appalaches) region of Quebec, serving about 26,000 in a predominantly urban setting. Retail and civic landmarks inside the code include Musée minéralogique et minier (KB3), Former asbestos open-pit mines and Mont Adstock (nearby) — the places where purchases in G6G actually happen.

What is the sales tax rate for FSA G6G in Quebec?

The combined sales tax rate for postal code FSA G6G in the Thetford Mines area of Quebec is 14.975%. This consists of the 5% federal GST plus a 9.975% provincial sales tax (PST/QST/RST), calculated separately on the purchase price.

How do I calculate tax for a purchase in Quebec (FSA G6G)?

To calculate the total price including sales tax for any purchase in Quebec, multiply the purchase price by 1.14975. For example, a $100.00 purchase costs $114.98 total, with $14.97 in sales tax.

For the reverse calculation, divide the total price by 1.14975 to find the pre-tax amount. Run the example above backwards and $114.98 paid in Quebec resolves to $100.00 before tax and $14.97 of tax.

Does Quebec use HST or separate GST and PST?

Quebec uses a dual GST + PST/QST system. The 5% federal GST and 9.975% provincial QST are calculated separately on the purchase price. Businesses must register with both the CRA and the provincial tax authority.

What kind of area is G6G — urban, suburban or rural?

G6G is a predominantly urban code serving about 26,000, within the Chaudière-Appalaches (Les Appalaches) region. Retail density is high, which means a large share of taxable transactions here are in-person, prepared food, and services rather than shipped goods.

Do local taxes in G6G change what I pay?

Not the sales tax itself — Quebec levies 14.975% province-wide and there is no municipal sales tax in Canada. What can differ by municipality are the separate levies that sit outside sales tax: accommodation and lodging taxes on short-term stays, and in some provinces local levies on prepared food or alcohol.

So a hotel folio or restaurant bill from Thetford Mines can total more than 14.975% while a retail receipt from the same street does not. Check the municipality's own schedule for those, and see the Quebec sales tax guide for the province-wide rules.

How does FSA G6G map to a sales tax rate?

The Forward Sortation Area (FSA) is the first three characters of a Canadian postal code. G6G falls within the range assigned to Quebec, specifically the Thetford Mines area. Canada sets sales tax provincially rather than municipally, so the FSA's job here is to place the buyer: once you know a delivery address sits in G6G, you know it is a Quebec sale and you charge 14.975%. That matters most for shipped orders, where the buyer's postal code — not your own — decides the rate.
