Canada workflow
Province selector before you invoice
Before a Canadian quote or invoice is useful, you need the province model right. This page exists to route business users toward GST only, HST, GST plus PST, or Quebec TPS plus TVQ without forcing them to memorize the whole table.
This is a workflow page, not a filing guide. Use it to choose the right display model and then move into the calculator or invoice tool.
Ontario HST 13%
One-line HST workflow for a common province.
British Columbia GST+PST
Two-part rate model inside the shared Canada calculator.
Quebec TPS/TVQ
Separate Quebec tax-line workflow.

Start with the customer province
The practical billing question is not 'what is the Canada tax rate?' but 'which province model am I using for this sale?'
That single decision changes whether you show one line of HST, one line of GST, or separate tax lines such as Quebec TPS and TVQ.
- HST provinces usually allow one visible HST line.
- GST-only provinces keep the display simple.
- GST+PST and GST+QST models need more explicit line handling.
When Quebec breaks the generic template
Quebec is the most obvious place where generic one-line tax display falls short. If the workflow hides both taxes in one total, the invoice becomes harder to audit and explain.
That is why CalcBusiness keeps a dedicated Quebec calculator and dedicated Quebec cluster pages.
Current scope
This cluster is intentionally limited to Canada sales-tax and invoice workflows.
- Source of truth is the shared ca-tax-2026 dataset.
- These pages support quotes, invoices, province selection, and Quebec two-line tax display.
- Income tax, payroll, and province-specific filing edge cases are outside this sales-tax cluster's scope.
Canadian sales tax: common questions
GST, HST, PST, QST — what is the difference?
GST is the 5% federal Goods and Services Tax charged everywhere. HST is a single harmonized tax that combines the federal and provincial portions in provinces like Ontario and the Atlantic provinces. PST is a separate provincial sales tax added on top of GST in provinces such as British Columbia, Saskatchewan, and Manitoba. QST is Quebec's own provincial tax (TVQ), administered by Revenu Québec alongside the federal GST (TPS).
When do I have to register to collect sales tax?
Most businesses must register for GST/HST once taxable revenue passes the CAD 30,000 small-supplier threshold over four consecutive quarters. Provinces with a separate PST, and Quebec with the QST, have their own registration rules, so check both the federal and provincial requirements.
How should tax appear on a Canadian invoice?
Show the pre-tax subtotal first, then the tax as a clearly labelled line or lines, then the final amount due. In provinces with two taxes — and especially in Quebec — keep GST/TPS and PST/TVQ on separate rows so the client and the accounting trail can see exactly what was charged.
Do these tools give tax advice?
No. They apply the verified 2026 dataset rates to help you plan quotes and invoices. Unusual supplies, exemptions, and filing edge cases still need review against the Canada Revenue Agency or Revenu Québec, or with an accountant.
