Quebec tax workflow
Quebec TPS/TVQ workflow
Quebec is important enough in the Canada cluster to justify its own entry point. The workflow is not just a combined rate. It is also about keeping TPS and TVQ visible as separate lines from quote through final invoice.
These Quebec pages are targeted routes inside an English-first site. They are not a full bilingual rebuild.

Why Quebec gets separate treatment
Quebec business workflows regularly need TPS and TVQ as two visible lines, not one compressed total.
That changes how the user checks the math, how the invoice reads, and how the accounting trail looks later.
English and French entry points
The repo stays English-first overall, but Quebec pages can be targeted where that helps the workflow.
That means a focused FR route is useful without forcing the whole site into a full language switch architecture.
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.
Preserve the two tax accounts through the workflow
Record the TPS registration number, TVQ registration number, taxable subtotal, 5% TPS, and 9.975% TVQ as distinct fields rather than only saving the 14.975% combined effect. That separation makes a quote easier to transfer into an invoice and makes later reconciliation against the two returns less ambiguous.
