Shopify Store Accounting and Tax in Canada (2026)

By Dellendo Farquharson, BOMCAS Canada

Tax year: 2026. Sources reviewed November 1, 2026.

Quick answer: Shopify accounting in Canada usually starts with you as the vendor of record. In the 2026 tax year you charge GST/HST based on place-of-supply rules, track inventory for cost of goods sold, and may also need B.C. PST, Saskatchewan PST, Manitoba RST or Quebec QST on your own storefront sales. Marketplace channels connected to Shopify can add platform tax collection and Part XX reporting on top.

Shopify makes checkout feel automatic. Canadian tax compliance does not. The difference between a clean year-end and a scramble is whether your store’s tax settings, inventory counts and payout reconciliations match what the CRA and the provinces expect for 2026.

BOMCAS Canada supports Shopify merchants from our Edmonton office and remotely across Canada. Start with our services page or bookkeeping services in Edmonton if you want monthly books that already speak GST/HST.

Tax year note: Rates and registration thresholds below were checked on November 1, 2026 against CRA GST/HST pages (including digital-economy rate lists) and B.C. Bulletin PST 142 (revised March 2025; Online Marketplace Facilitators and Sellers, and Online Marketplace Services). Nova Scotia HST is listed at 14%; Ontario at 13%; New Brunswick, Newfoundland and Labrador, and Prince Edward Island at 15%; GST-only provinces and territories at 5%.

Shopify store versus marketplace channel

On a classic Shopify storefront you set prices, issue the invoice, control fulfillment and receive the customer payment (often through Shopify Payments). You are the supplier for GST/HST purposes on those sales. When you also list the same SKUs on Amazon, eBay or another marketplace, that channel may be a distribution platform with its own collection duties for non-registered vendors. Keep channel sales in separate revenue and tax payable accounts so you can see who collected what.

GST/HST: small-supplier threshold and voluntary registration

The CRA’s when to register / small-supplier rules still centre on $30,000 of worldwide taxable supplies (including associates) measured in calendar quarters. Stay at or under $30,000 in every quarter and over the last four quarters and you are generally not required to register, though you may choose to. Cross $30,000 in one quarter and you must charge on the supply that puts you over. Cross it only on a four-quarter basis and the CRA’s timing table gives you until the end of the following month before you must charge on later supplies.

Growing Shopify brands often register early. Inventory, apps, theme developers, freight and photography all carry GST/HST that becomes recoverable as ITCs once you are a registrant making taxable supplies. Document every ITC with a proper invoice showing the supplier’s GST/HST number where required.

Place-of-supply configuration in the store

For tangible goods, Memorandum 3-3-3 and the CRA place-of-supply page look at where you deliver or make the goods available. Mailing or couriering to a provincial address generally makes the supply in that province. Configure Shopify tax (or a tax app) so:

• Alberta, B.C., Manitoba, Saskatchewan, Quebec and the territories charge 5% GST at the federal layer (provincial sales taxes are separate systems).
• Ontario charges 13% HST.
• Nova Scotia charges 14% HST.
• New Brunswick, Newfoundland and Labrador, and Prince Edward Island charge 15% HST.

Zero-rated and exempt items (basic groceries are the usual example) need product-level tax codes, not a store-wide rate. Digital downloads and SaaS-style subscriptions use different place-of-supply rules focused on the recipient’s usual place of residence or business; do not reuse your goods matrix for those products.

Digital-economy rules when you sell from abroad into Canada

If your operating company is non-resident and not carrying on business in Canada in the traditional sense, the July 2021 digital-economy measures may still require registration when you sell qualifying goods from Canadian inventory or certain cross-border digital products to Canadians. Threshold amounts for those measures also use a $30,000 concept over a 12-month period for applicable revenues. Canadian-resident Shopify stores on the normal regime simply follow RC4022. Non-residents should read Guide RC4027 and the CRA digital-economy registration finder before they assume a simplified account is enough.

Provincial PST, RST and QST on your storefront

Your own Shopify checkout is not an “online marketplace facilitator” sale under B.C. Bulletin PST 142 (revised March 2025). That bulletin generally assigns PST collection on facilitated marketplace sales to the facilitator; it also reminds sellers that sales outside the marketplace (including a seller’s own website) can still require the seller to register. Practically:

• British Columbia PST (7%) often applies to taxable goods sold to B.C. consumers on your storefront once you meet provincial registration tests.
• Saskatchewan PST and Manitoba RST have their own remote-seller and marketplace rules; check each province’s finance site when your ship-to volume grows.
• Quebec QST may require registration under the general or specified system depending on where the supplier resides and whether a platform is involved. Revenu Québec materials for suppliers outside Quebec describe distribution-platform collection in parallel with GST/HST digital-economy ideas.

Do not rely on GST-only settings if you ship taxable goods into B.C., Saskatchewan, Manitoba or Quebec in volume.

Part XX reporting: when it touches a Shopify merchant

Part XX of the Income Tax Act obliges reporting platform operators to report reportable sellers who sell goods or provide certain services through a platform. A one-brand merchant on its own Shopify domain is primarily the business filing T1/T2 income, not a “seller reported by Shopify” in the Amazon FBA sense. The moment you sell as a third-party seller on a marketplace, expect that marketplace to send you annual Part XX information by January 31 and to file with the CRA. Keep those statements with your 2026 books for the January 31, 2027 deadline cycle.

Inventory, COGS and landed cost

Shopify’s inventory quantity is not a tax return. The CRA still expects an annual inventory for goods held for sale. Build landed cost (product, inbound freight, duty, and non-recoverable import charges) into each SKU. Opening inventory plus purchases minus closing inventory equals cost of goods sold. Returns that go back to sellable stock must re-enter inventory; damaged returns need a clear write-off policy. Manufacturers and private-label brands should also track work-in-progress and packaging supplies as the CRA inventory page describes.

Fees, apps and capital assets

Break out Shopify subscription fees, payment processing, app charges, theme costs and contractor invoices. Recurring SaaS is usually an expense (with ITCs if registered). Custom software development or a major computer refresh may be capital: Class 12 for much application software, Class 50 at 55% for general-purpose computers and systems software acquired after March 18, 2007, subject to any enhanced first-year CCA the CRA classes page allows for eligible property acquired after April 15, 2024 and available for use before 2027. Confirm the class before you expense a $4,000 workstation as “office supplies.”

Payout reconciliation that auditors understand

Each Shopify Payments payout should reconcile as: gross sales, minus discounts and returns, minus fees and chargebacks, plus or minus reserves, equals the deposit. Map gift cards and store credits carefully; unredeemed balances can create liability issues. If you pay staff or contractors who handle fulfillment, fold remittances into the same monthly close we use on payroll services.

Corporate versus sole-proprietor filing

Many Shopify brands incorporate once contribution margins stabilize. Corporate tax and owner compensation then split between the T2 and the owner’s T1. Our corporate tax and personal tax pages outline how we handle that from Edmonton. Cross-border inventory purchasing also overlaps with our notes on import-export businesses in Canada.

2026 month-end rhythm for Shopify

1. Export orders, tax and payout reports; lock the period in your accounting file.
2. Reconcile GST/HST collected by rate to the return worksheet.
3. Post inventory receipts and COGS; investigate negative stock.
4. Review PST/QST filings if registered.
5. Clear owner draws and personal orders placed through the store.
6. Backup theme, order and accounting exports together.

Frequently asked questions

When must a Shopify store register for GST/HST?

Most stores must register once worldwide taxable supplies (with associates) exceed the $30,000 small-supplier threshold in a single calendar quarter or over four consecutive calendar quarters. You may also register voluntarily to recover ITCs on inventory and apps.

Which tax rate do I charge a customer in Nova Scotia?

For tangible goods, place-of-supply rules generally treat a mail or courier delivery to a Nova Scotia address as a supply in Nova Scotia. The CRA list reviewed for this article shows HST at 14% in Nova Scotia. Digital products use different place-of-supply rules; configure tax settings by product type.

Does Shopify file Part XX reports about my store?

Shopify may be a reporting platform operator for marketplace or certain platform features that connect third-party sellers. A typical single-brand Shopify merchant selling only its own goods on its own storefront is the vendor, not a Part XX ‘seller on someone else’s platform’ in the Amazon sense. If you also sell as a seller on a marketplace channel, expect Part XX information from that marketplace.

How should I record Shopify Payments payouts?

Record gross sales, discounts, returns, Shopify fees and payment processing fees on separate lines, then tie the net deposit to the bank. Never book only the payout as revenue.

Do I need B.C. PST if I already charge GST?

Often yes for taxable goods delivered to B.C. purchasers when you sell on your own storefront. Marketplace-facilitated sales can shift PST collection to the facilitator under Bulletin PST 142, but your own Shopify storefront is usually your registration problem.

Can I claim ITCs on Shopify monthly subscription fees?

If you are a GST/HST registrant and the subscription is acquired for use in your commercial activities, you generally claim ITCs on the tax paid, subject to the usual documentation and restricted ITC rules.
