GST/HST for Non-Resident Digital Businesses Selling Into Canada

Why the Rules Changed

For years a foreign business could sell digital services into Canada without charging tax, while a Canadian competitor selling the same thing had to. The 2021 measures closed that gap by attaching the obligation to where the customer is rather than where the seller is.¹

The same logic drove the EU's OSS scheme and the post-Wayfair US position: consumption taxes follow consumption. Compare EU VAT OSS and IOSS and the economic nexus guide.

Simplified or Full: The Real Trade-Off

One Registration, Many Rates

Registering once does not mean charging one rate. The rate follows the customer's province, so the same registration produces GST alone for an Alberta customer, HST for an Ontario customer, and GST plus provincial tax elsewhere. The structure is set out in PST vs GST/HST.³

That makes evidence of customer location part of your compliance record rather than a billing detail — it is what justifies the rate you charged.

Consumers Versus Registered Businesses

The regime is aimed at sales to consumers who cannot self-assess. Sales to GST/HST registered Canadian businesses are generally handled differently, because those customers account for the tax themselves — mechanically similar to the EU reverse charge.

The practical consequence is that a B2B-heavy seller may sit below the threshold on qualifying sales while a B2C seller with identical revenue crosses it. Customer mix, not just turnover, decides whether you register.

Platforms Carry Their Own Duty

Distribution platform operators facilitating sales into Canada have obligations in their own right, which can cover sales made through them by non-resident vendors. If you sell through a marketplace as well as direct, establish which sales the platform is accounting for before assuming your own threshold count is complete — the same split described in marketplace facilitator laws.

Simplified Registration vs. Full Registration

Non-residents selling digital products to Canadian consumers face a genuine choice, and picking the wrong one costs money in a way that is hard to reverse later.

• Simplified GST/HST registration is built for businesses with no physical presence in Canada. Registration and filing are streamlined — but the trade-off is decisive: you cannot claim input tax credits. Every dollar of Canadian GST/HST you pay on your own costs becomes a permanent expense.
• Full (normal) registration demands more — a business number, standard returns, the usual record-keeping — and in exchange you recover tax on Canadian inputs through input tax credits, exactly as a domestic business does.

The rule of thumb is the size of your Canadian cost base. A business that merely sells into Canada and buys nothing there loses little under the simplified regime. A business buying Canadian hosting, contractors, advertising, or fulfilment is handing over recoverable tax for no reason.

Quebec Registers You Twice

Quebec is the trap that catches non-residents who assumed one Canadian registration would be enough. Revenu Quebec administers both the federal GST and the provincial QST, and it runs its own separate registration regime for non-resident suppliers of digital services to Quebec consumers.

So a digital business selling across Canada can need the federal simplified registration and a separate Quebec QST registration, with different returns and different filing calendars. Selling into Quebec at 14.975% while registered only federally leaves the 9.975% QST uncollected and owed.

What Counts as a Canadian Consumer

The obligation turns on selling to consumers who are not registered for GST/HST — business customers providing a valid registration number are generally handled through self-assessment instead. That makes customer status a data problem: your checkout has to capture and validate registration numbers, and your records have to prove which customers were which.

Location is the second data problem. Canada's rules rely on indicators of a customer's usual place of residence — billing address, IP address, payment instrument — and expect a consistent method applied across the customer base rather than a per-sale judgement. A business that stores no location indicator at the time of sale cannot reconstruct one during an audit.

The Five-Step Method

1. Measure sales to Canadian consumers over twelve months. Track revenue from customers in Canada who are not GST/HST registrants against the CAD $30,000 threshold on a rolling basis.
2. Decide between simplified and full registration. Weigh the lighter administration of the simplified regime against the loss of input tax credits, which matters most if you have Canadian input costs.
3. Register before you begin charging. Complete the registration and obtain your account before collecting tax, as with any jurisdiction.
4. Charge the rate for the customer's province. Apply GST, HST or GST plus provincial tax according to where the customer is located rather than one national rate.
5. File and remit on the assigned schedule. Report on the cadence the CRA assigns, and keep evidence of customer location because it determines the rate you applied.

Continue the chain

• Input tax credits — what the simplified regime gives up.
• PST vs GST/HST — which rate applies in which province.
• EU VAT OSS & IOSS — the same idea in the European system.
• GST/HST compliance — the wider Canadian obligations.
