Example and reference only. This calculator produces illustrative estimates to help you plan. Figures are not exact, do not account for your full circumstances, and must not be used to file, remit, or make financial commitments. Confirm every amount with the CRA, Revenu Québec, or your accountant before acting on it. Nothing here is tax, accounting, or financial advice.
GST/HST Calculator
Work out what to charge, or back out the tax from a total you have already been paid. Covers GST, HST, and the provinces that run a separate PST, RST, or QST.
HST combines the federal and provincial portions into one tax, filed and remitted to the CRA in a single return.
Rates across Canada
You must register for GST/HST once your worldwide taxable revenue passes $30,000 in a single calendar quarter or over four consecutive quarters. Registering voluntarily below that threshold lets you claim input tax credits on your own purchases.
