Shopify GST/HST for Canadian Sellers: Decision Tree, Setup, and 2026 Rates

If you sell on Amazon Canada, you know that Amazon collects the sales tax for you under marketplace facilitator rules. Most Canadian Shopify sellers assume the same thing happens on Shopify. It does not. Shopify is not a marketplace. You are the seller of record on every order, you set the tax rates yourself, you collect the tax through the checkout, and you remit it to CRA and the provinces. This is the number-one reason Shopify sellers end up with surprise sales-tax bills.

This guide is the framework we walk every Shopify client through: the decision tree on whether to register, the multi-province tax structure, how to configure Shopify Admin correctly, and the five mistakes that cause the biggest reassessments at audit. 2026 rates throughout.

The short answer

Shopify vs Amazon: the tax difference that bites

The two platforms are treated very differently under Canadian sales tax law.

The single most expensive misunderstanding we see is sellers who run both Amazon and Shopify assuming Shopify handles the tax the same way Amazon does. On Shopify, if you do not collect, you owe it out of pocket plus penalties and interest when CRA finds you.

The decision tree: do you need to register?

Three questions in order. The answers tell you exactly what to do.

1. Are your worldwide taxable sales (across every channel: Shopify, Amazon, Etsy, wholesale, retail, anywhere) over $30,000 CAD in any rolling 12-month window?
   • No: you are a small supplier. GST/HST registration is voluntary. You may want to register anyway to claim back input tax credits on Shopify fees, ads, software, and inventory.
   • Yes: registration is mandatory. You have 29 days from the date you cross the threshold to apply.
2. Do you sell into BC, Manitoba, Saskatchewan, or Quebec?
   • No: only GST/HST applies. You set Shopify to charge GST or HST based on the destination province.
   • Yes: see the provincial PST/QST thresholds below. You may need a separate provincial registration for each one.
3. Are you a non-resident of Canada selling to Canadian customers through Shopify?
   • No: standard Canadian-resident GST/HST registration applies.
   • Yes: the rules depend on whether you “carry on business in Canada” (inventory in Canada, agents in Canada, etc.). See our companion guide on FBA Canada inventory and GST/HST registration for the full non-resident framework. Either way, the recommended path for non-resident sellers is full GST/HST registration so you can claim back the input tax credits on your Canadian-side costs: Shopify fees, advertising spend, inbound freight, customs duties, and imports. Recoverable ITCs frequently offset the GST you remit on direct Canadian sales. We handle the full registration and ongoing filings for non-resident Shopify sellers.

Provincial PST and QST thresholds for Shopify sellers

The four provinces with separate provincial sales tax have their own registration thresholds. Sell over the threshold into one of these provinces and you need a separate provincial registration.

These thresholds and rules change occasionally. The current snapshot is accurate as of 2026, but always verify before relying on a registration decision.

The Shopify Admin tax setup, and why it goes wrong quietly

Unlike the marketplaces, Shopify only charges what its tax settings tell it to charge. The setup involves enabling Canada as a tax region, entering each registration number with the right authority, confirming the store calculates the correct rate for every province you ship to, and flagging any products that should not be taxed at the standard rate. None of it is hard on a good day.

The problem is that it fails silently. A missing registration number means the store simply does not collect for that authority. A misclassified product charges the wrong rate on every order. A rate that is right for Ontario and wrong for BC looks fine in the dashboard. Nothing warns you, so stores run for months collecting the wrong tax, and the shortfall comes out of the seller’s pocket at reassessment, with penalties and interest on top. When we take on a Shopify client, verifying the entire tax configuration against their actual registrations is the first thing we do, before any return gets filed on top of bad numbers.

The five mistakes that cause Shopify sales-tax reassessments

1. Not registering after crossing $30k. Sellers assume Shopify is “handling it like Amazon” and find out at year-end that they owe the entire GST/HST on every taxable sale, plus failure-to-register penalty, plus interest.
2. Forgetting BC PST. The BC threshold is $10,000, much lower than the federal $30,000. Sellers cross the BC threshold without realizing it and never register, even though they collect federal GST correctly.
3. Wrong product tax classification. Charging tax on zero-rated basic groceries (for example), or failing to charge tax on a taxable category, both create reassessments.
4. Skipping the registration number entry in Shopify Admin. Shopify needs your actual registration numbers to enable tax collection for each authority. If you register but never enter the number, your store does not collect.
5. Not reconciling Shopify reports to your GST/HST return. Shopify’s tax reports must reconcile to what you report to CRA. Mismatches get noticed.

Input tax credits: the reason to register early

Once you are GST/HST registered, you can claim back the GST you paid on Shopify subscription fees, transaction fees, payment processing fees, advertising spend, software, inventory, and other business inputs. For a typical small Shopify seller, those input tax credits frequently exceed the GST collected on Canadian sales in the early years.

This is why we often recommend voluntary registration well before the $30,000 threshold. The CRA rule is one-way: once you register, you can recover GST on past purchases going back four years (with proper documentation). You do not lose anything by registering early, and you potentially recover meaningful tax that you have been paying with no path to recovery.

Frequently asked questions

Does Shopify collect GST/HST on my Canadian sales like Amazon does?

No. Shopify is a technology platform, not a marketplace facilitator. You are the seller of record on every order. You configure the tax rates in Shopify Admin and the store collects the tax on your behalf at checkout, but you are the one who registers, files, and remits to CRA and the provinces.

When do I have to register for GST/HST as a Canadian Shopify seller?

Once your worldwide taxable sales pass $30,000 CAD in any rolling 12-month period. The 12-month window can be any consecutive 12 months, not just a calendar year. You have 29 days from the day you cross the threshold to apply for GST/HST registration with CRA.

Do I need a separate provincial PST registration for BC, Saskatchewan, Manitoba, or Quebec?

Possibly. Each province has its own rules and thresholds. BC PST kicks in at $10,000 in BC-destined sales. SK PST and MB RST apply with no minimum threshold if you sell taxable goods into the province. Quebec QST applies at $30,000 in Quebec sales. If you are over the relevant threshold in any province, you register with that provincial authority directly, separate from your CRA GST/HST registration.

How do I enter my tax numbers in Shopify Admin?

Each registration number has to be entered against the right tax authority in Shopify’s tax settings, and the store only collects for the authorities you have entered. The risk is not the data entry, it is what you cannot see afterward: a number under the wrong authority or a skipped province collects incorrectly on every order with no warning. Setup and verification against your actual registrations is part of our Shopify onboarding, so the store is provably right before the first return is filed.

What tax do I charge on US or international sales from my Shopify store?

Sales to customers outside Canada are zero-rated exports for Canadian GST/HST purposes. You do not charge Canadian tax on those sales, but they still count toward your worldwide taxable sales for the $30k registration threshold. US state sales tax is a separate question and depends on whether you have economic nexus in any US state.

Can I register for GST/HST voluntarily even if I am under $30,000?

Yes. Voluntary registration is often the right call for new Shopify sellers because the input tax credits on Shopify fees, advertising, and inventory typically exceed the GST you would have to collect on early Canadian sales. The break-even is usually fast, and the recovered GST is real cash.

What happens if I never registered and CRA finds me?

CRA back-assesses the GST/HST you should have collected, generally for the prior four years (six years for negligent or wilful failures). Penalties for failure to register and late filing are added on top, and interest compounds at the prescribed rate. Net of input tax credits you can now claim, the bill is usually large but not catastrophic, particularly if you come forward voluntarily under the CRA Voluntary Disclosures Program before they contact you.

Do I have to charge tax on shipping charges in Shopify?

Yes. Shipping is treated as part of the consideration for the supply and is taxed at the same rate as the goods being shipped. Shopify handles this automatically if your tax settings are correct, but verify it on a test order.
