Frequently asked questions
What sales tax rates does the cheat sheet cover?
All 13 Canadian provinces and territories for 2026: the 5% federal GST, HST provinces (Ontario 13%, Nova Scotia 14%, New Brunswick, Newfoundland and Labrador, and PEI at 15%), PST provinces (BC and Manitoba 7%, Saskatchewan 6%), and Quebec QST at 9.975% — each with its reverse-tax divisor.
How do I reverse sales tax out of a receipt?
Divide the tax-included total by the divisor for the province — 1.13 in Ontario, 1.05 in GST-only provinces, 1.14975 in Quebec — and subtract to get the tax. The cheat sheet lists every divisor and includes worked examples.
When do I have to register for GST/HST?
Once taxable sales exceed $30,000 over four consecutive calendar quarters (or in one quarter). The cheat sheet covers the small-supplier rule, why voluntary registration can pay off through input tax credits, and the separate QST and PST registrations.
