CRA federal GST/HST tables and Revenu Quebec guidance on the GST and QST tax bases.
These references are not an approval of a tax rate. The calculator applies a percentage you enter manually. Selecting Canada changes the currency, not the applicable tax rules.

What still needs validation
Province, place of supply, classification and transaction date are required. Review each relevant provincial PST authority separately. A federal table alone does not approve every provincial rule.
Before a rate can become a preset
Each executable rule needs a specific legal citation, jurisdiction, transaction category, tax base, effective period, exceptions and rounding policy. It also needs independent expected-result tests and recorded human approval. A retrieval date is not an effective date or a tax-professional sign-off.
Calculation method
For a single proportional percentage, add tax using net × rate ÷ 100. To extract included tax, divide the total by (1 + rate ÷ 100). This manual method does not determine whether that percentage legally applies.
