Why Reverse Tax Calculation Matters
Receipts and invoices usually show only the tax-included total β not the pre-tax price. Reversing the calculation matters for bookkeeping, expense claims, and cross-border price comparisons. Because dividing by (1 + rate) isn't the same as simply subtracting the rate, doing this by hand is a common source of errors β select "Reverse" in the purchase-mode calculator above to handle it exactly.
History & Context
Canada's federal Goods and Services Tax (GST) was introduced in 1991 at 7%, later cut to 5% by 2008. Canada layers this federal GST with either a harmonized HST (in Atlantic provinces and Ontario) or separate provincial sales taxes (PST/RST/QST), creating one of the more varied consumption-tax landscapes among major economies.
Because Canada's sales tax structure varies by province β full detail available on this site's dedicated Canada Tax Rates pages β the 5% GST/HST figure shown here for the national comparison understates the true combined rate a shopper in an HST province (up to 15%) would actually pay.
Business Use Case
A business expanding across Canada must determine not just the 5% federal GST but whether each destination province uses HST, a separate PST, or (in Alberta and the territories) no provincial sales tax at all β see this site's Canada Tax Rates section for the full province-by-province breakdown.
