Tax is not one number across Canada
Ontario and the Atlantic HST provinces charge a single HST rate. Alberta and the territories are GST only. BC, Manitoba, and Saskatchewan add PST. Quebec uses GST plus QST. This calculator uses TradeInvoice’s province table so your estimate matches how we tax quotes and invoices.
Use it when a client asks “what’s the total with tax?” before you open a full document — then put the same province on the real quote or invoice.
Estimates vs filing
This is a field and office estimate for job pricing. It is not tax advice. Exemptions, place-of-supply rules, and registration thresholds are your responsibility with a bookkeeper or CRA guidance.
