Canada sales-tax and invoice workflows

This cluster is built around the shared Canada sales-tax dataset and the live GST/HST plus Quebec TPS/TVQ tools. The goal is practical workflow coverage: province selection, invoice tax display, quote handoff, and Quebec-specific two-line tax presentation.

This Canada cluster intentionally stops at sales-tax and invoice workflows. It does not claim payroll, income-tax, or filing completeness.

GST/HST Canada

Add or extract Canada sales tax by province or territory.

TPS/TVQ Quebec

Model Quebec invoice tax with separate TPS and TVQ lines.

Province selector workflow

Choose the right provincial rate model before quoting or invoicing.

Invoice tax workflow

Show subtotal, tax lines, and total clearly on Canadian invoices.

GST/HST vs QST/TPS/TVQ

Know when one tax line is enough and when Quebec needs two.

Quote to invoice workflow

Move from quote subtotal to final taxed invoice without guesswork.

Province-first workflow

Start with the rate model, not the final total.

Canada billing errors often start when province context is missing until the final invoice. This cluster fixes that by treating province selection as the first decision.

Once the province is set, the right display model follows: GST only, HST, GST plus PST, or Quebec TPS plus TVQ.

Invoice and quote workflows

Built for real business documents.

Canadian clients should be able to read the subtotal, tax lines, and final amount due without reconstructing the math themselves.

Quebec remains the clearest special case because TPS and TVQ should usually appear as separate lines on the invoice.

Quebec specific handling

Separate lines win.

  • TPS and TVQ should stay visible as separate lines.
  • Quote and invoice flows should preserve Quebec context all the way through.
  • French Quebec routes can stay targeted without turning the whole site bilingual.

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 stay out until official-source datasets and test fixtures are added.
