Shopify Seller Taxes Canada: Complete 2025 Guide

Set up Canadian taxes correctly in Shopify, understand your GST/HST obligations, and avoid CRA penalties — a practical guide for Canadian Shopify merchants.

Setting Up Canadian Taxes in Shopify

Shopify has built-in Canadian tax settings that, when properly configured, automatically calculate and collect the correct GST/HST and provincial sales tax for each customer's shipping province. To configure:

• Go to Settings > Taxes and Duties in your Shopify admin
• Select Canada as your store country
• Enter your GST/HST registration number once you have one
• Shopify automatically applies HST rates for harmonized provinces (ON, NS, NB, NL, PEI) and separate GST + PST for BC, SK, MB, and GST + QST for Quebec
• Enable "Charge taxes on shipping rates" if your province requires it (varies)

When Must You Register for GST/HST as a Shopify Seller?

You must register for GST/HST once your Shopify store's total Canadian taxable revenues exceed $30,000 in any 12-month period. This includes revenue from all sources, not just Shopify. Once registered, you collect GST/HST from all Canadian customers and remit to CRA quarterly or annually. Do not wait until the end of the year — monitor your running 12-month revenue and register promptly when you cross the threshold.

Shopify Tax Reports for CRA Filing

Shopify provides tax reports under Analytics > Reports > Taxes. These reports break down taxes collected by province and can be exported. When filing your GST/HST return, you need:

• Total taxable sales (line 101 on GST/HST return)
• Total GST/HST collected (line 103)
• Total input tax credits — GST/HST paid on your Shopify fees, advertising, inventory purchases (line 106)
• Net tax owing (line 109) = line 103 minus line 106

Shopify fees themselves (monthly subscription, transaction fees) are charged with GST — keep these as ITCs on your return.

Income Tax on Shopify Revenue

All revenue earned through Shopify is taxable business income. For incorporated businesses, this flows into the T2 corporate tax return. For sole proprietors, it goes on Schedule T2125 of your personal T1 return. You deduct all legitimate business expenses (COGS, Shopify fees, advertising, shipping, packaging, software subscriptions) against your gross revenue to arrive at net business income.

Shopify Payments and Tax Reporting

Shopify Payments (the built-in payment processor for Canadian merchants) does not issue a T4A or 1099 to Canadian sellers. However, if you use other payment processors like PayPal and your revenue exceeds certain thresholds, PayPal may issue reporting. Regardless, you are responsible for reporting all income whether or not you receive a tax slip. Keep records of all Shopify payouts, which appear in your Shopify Payments dashboard.

Common Shopify Tax Mistakes by Canadian Sellers

• Not registering for GST/HST after crossing the $30,000 threshold
• Charging the wrong provincial rate (e.g., charging Ontario 13% HST to a BC customer who should pay 5% GST + 7% BC PST separately)
• Failing to remit taxes collected — collected tax is held in trust for CRA
• Not claiming ITCs on Shopify subscription fees and app costs
• Treating refunded orders — you can claim back the GST/HST on refunds
• Ignoring US state sales tax obligations when selling significantly into the US
