When you sell products or services across Canada as a small business, GST/HST rules aren't the same everywhere. Different provinces use different tax systems: some apply GST only, others use HST (a combined federal and provincial tax), and rates vary by location. Understanding these differences is crucial for accurate pricing, collections, and remittance. This guide explains how multi-province sales work under Canadian GST/HST law and how to handle them correctly for your 2026 filings. Canada's sales tax landscape is split into three models: GST-Only Provinces: - Alberta, British Columbia, Manitoba, Saskatchewan - Apply federal GST only (5%) - You collect and remit GST to the Canada Revenue Agency HST Provinces: - Ontario, Nova Scotia, Prince Edward Island, Newfoundland and Labrador, New Brunswick - Apply HST (combined rate ranging from 13% to 15%) - Single tax collected and remitted Dual Tax Provinces (GST + PST): - Quebec, Quebec, British Columbia, Saskatchewan, Manitoba - Collect both GST (5%) and provincial sales tax (PST) separately - Remit to both federal CRA and provincial authorities If your small business operates across these zones, you're managing multiple tax rates and filing requirements simultaneously.
Yes. The tax rate applied is determined by the customer's location in Canada, not your business location. If you ship goods to Ontario (HST province), you charge HST even if your business is in Alberta (GST-only). For services, it depends on where the service is used or the customer's province of residence.
You must register for GST/HST federally and track your total Canadian sales combined. You'll collect the appropriate tax for each province and file separate returns (or combined HST returns) for provinces where you have taxable supplies. Your accounting software should automatically calculate the correct rate by customer location.
Yes. You can claim ITCs for GST/HST paid on eligible business purchases regardless of where you bought them, as long as the purchases relate to making taxable supplies in Canada. Keep detailed records organized by the tax rate paid and the province, especially when allocating shared expenses.
No. You register once federally with the CRA for GST/HST, and that registration covers all provinces. However, some provinces may require additional provincial tax registration depending on your business type. Check with your provincial government or tax professional to confirm all requirements for your specific situation.
Most multi-province businesses file a single GST/HST return reporting sales and purchases across all provinces combined, with the tax calculated at the appropriate rate for each location. Your accounting software should handle this automatically. Review CRA reporting requirements for your specific filing frequency (quarterly or annual).
