Shopify is based in Canada, and many Shopify merchants are Canadian. When Canadian Shopify store owners sell to US customers, they generate US-source income that may have US tax implications. An ITIN ensures proper tax documentation and helps claim Canada-US Treaty benefits.
Shopify Payments and US Tax for Canadians
Shopify Payments (powered by Stripe) is available to Canadian merchants. When you sell to US customers, your income is US-source. Shopify may request W-8BEN documentation for Canadian merchant accounts receiving significant US revenue.
With an ITIN and the Canada-US Tax Treaty, you correctly document your status as a Canadian resident receiving business income. This prevents incorrect withholding and ensures your Shopify payouts arrive without deductions.
US Sales Tax (Different from Income Tax)
Important distinction: US sales tax is separate from US income tax. Shopify automatically calculates and collects US state sales tax if you enable it (through Shopify Tax). As a Canadian seller, you may have nexus in states where you have physical presence (including FBA warehouses).
Your ITIN is for US income tax purposes — specifically for W-8BEN documentation and any required US income tax filings. Sales tax is handled separately at the state level.
Canadian Shopify Sellers with US LLCs
Many Canadian Shopify store owners operate through a US LLC for cleaner business structure. The LLC's EIN goes on payment processor accounts. Your personal ITIN ties you to the LLC for Form 5472 compliance. This setup also enables US bank accounts for Shopify payouts.

Do Canadian Shopify sellers need an ITIN?
If you receive W-8BEN documentation requests from Shopify or Stripe for significant US-source income, yes. An ITIN enables correct tax documentation under the Canada-US Treaty.
Does the Canada-US Tax Treaty help Shopify sellers?
