How to charge GST/HST on an invoice, by province

Charge the rate of the province your customer is in: 5% GST in Alberta, 13% HST in Ontario, 15% in most of Atlantic Canada and 14% in Nova Scotia.

For most services, and for goods you deliver, the rate on the invoice is the one for the province where your customer is, not where you are. A Calgary business invoicing a client in Toronto charges 13% HST, not 5% GST. You must register and start charging once your taxable sales pass $30,000 in a single calendar quarter, or over four consecutive calendar quarters; below that you are a small supplier and registering is optional.

1. Alberta, Northwest Territories, Nunavut and Yukon: 5% GST.
2. British Columbia: 5% GST, plus 7% PST if you are registered for BC PST.
3. Manitoba: 5% GST, plus 7% RST if you are registered with Manitoba.
4. Saskatchewan: 5% GST, plus 6% PST if you are registered with Saskatchewan.
5. Quebec: 5% GST, plus 9.975% QST if you are registered for QST.
6. Ontario: 13% HST.
7. New Brunswick, Newfoundland and Labrador, and Prince Edward Island: 15% HST.
8. Nova Scotia: 14% HST (it was 15% until 1 April 2025).

What the invoice must show depends on its total. From $100 your customer needs your business name, your GST/HST registration number, the date, the total and the tax charged before they can claim it back; from $500 they also need their own name, your payment terms and a description of what you supplied. Todah prints the rest on every invoice already; for your registration number, put it in Settings → Business → Invoice Footer Note (for example "GST/HST 123456789 RT0001") and it prints on every document.

1. Settings → Books & Tax → Set Up from a Province adds the right taxes for a province in one step; add a second province the same way.
2. Each invoice line carries its own rate, so a customer in another province gets that province's rate on the line, and a mixed invoice adds up correctly.
3. The tax collected is reported by rate in Reports, ready for your return.
