What sales tax do I charge on a Canadian invoice?

It depends on the province: 5% GST everywhere, HST (a combined rate) in provinces like Ontario, or GST plus a separate PST/QST in provinces like BC and Quebec. Charge based on where the sale is taxable and show your GST/HST number.

Do I need a GST/HST number to invoice in Canada?

You must register once you pass the small-supplier threshold (generally $30,000 in revenue). Once registered, your GST/HST number must appear on invoices where you charge the tax.

What is the difference between GST and HST?

GST is the 5% federal tax charged nationwide. HST is a single harmonized rate that bundles GST with provincial tax in participating provinces, so you charge one combined rate instead of two.

Canadian Invoices: GST, HST, PST & QST Explained

Canada has one of the more layered sales-tax systems: a federal tax plus provincial taxes that differ by province. If you’re registered, your invoices need to apply the right combination and show your tax number. Here’s how it works in plain terms.

GST, HST, PST and QST

GST — the 5% federal Goods and Services Tax, charged across Canada.
HST — the Harmonized Sales Tax, which combines GST and provincial tax into one rate in provinces like Ontario and the Atlantic provinces.
PST — a separate Provincial Sales Tax in provinces such as British Columbia, Saskatchewan and Manitoba, charged on top of GST.
QST — Quebec’s provincial tax, administered alongside GST.

What to show on the invoice

When you charge sales tax, show your GST/HST number, the tax applied per rate, and the totals before and after tax in CAD. If a sale involves both GST and a separate PST, list each as its own line so the customer can see the breakdown.

When do you register?

Most small businesses must register for GST/HST once revenue crosses the small-supplier threshold (generally $30,000 over four quarters). Below that you may register voluntarily. Provincial PST registration has its own rules by province.

This is general guidance, not tax advice. Rates and thresholds change and vary by province — confirm with the CRA, your province, or your accountant.
