Canada doesn’t have one sales tax — it has three. The federal Goods and Services Tax (GST) applies at 5% across the country. Five provinces have harmonized their provincial tax into a single combined rate called HST (Harmonized Sales Tax) and split the proceeds with Ottawa. The rest stack a separate provincial sales tax — called PST in BC, RST in Manitoba, QST in Quebec — on top of the 5% federal GST.
Quebec applies its QST after GST, not in parallel. A $100 purchase in Quebec is taxed 5% GST first ($5), then 9.975% QST on the now-$105 amount ($10.47). The effective combined tax is 14.975% × 1 + a tiny compound on the GST — about 15.0% total instead of the flat 14.975%. The calculator handles this automatically.
Restaurant receipts, contractor invoices, and most e-commerce checkouts show only the total. Reverse mode takes that grand total, applies the right provincial formula, and tells you the subtotal and each tax line — useful for HST input tax credit claims, expense reporting, or just settling a dispute with the receipt.
Zero-rated and exempt items (basic groceries, prescription drugs, residential rent, most financial services), point-of-sale rebates that some provinces grant on books and children’s clothing, the small-supplier $30,000 GST registration threshold, and First Nations status-card exemptions. For routine consumer purchases, the standard rates above are what you’ll see at the register.
