About the Canada GST/HST Calculator
Canada does not have one combined sales-tax rate. Ontario uses 13% HST; New Brunswick, Newfoundland and Labrador and Prince Edward Island use 15%. Nova Scotia changed from 15% to 14% on April 1, 2025. Other provinces and territories use 5% GST, sometimes with separate provincial taxes: British Columbia and Manitoba 7%, Saskatchewan 6%, and Quebec 9.975% QST. Quebec QST is calculated on the net selling price, not on a GST-inclusive subtotal: C$100 has C$5 GST plus C$9.975 QST before display rounding. The reference window covers January 2025 through November 10, 2026, not all historical or future tax rules. For ordinary Nova Scotia supplies, select the earlier date tax becomes payable or is paid; special transition cases require the CRA guidance. Zero-rated, exempt and provincial special-category supplies are outside this standard-taxable calculation.
