CRA Invoice Requirements Canada (2026) — GST/HST Fields & PDF
What a Canadian invoice needs for GST/HST input tax credits: business number, tax amounts, and tiered detail rules — plus PDF export.
Tax auditors search for sequential invoice numbers, correct tax lines, and immutable PDF archives. Cra Invoice Requirements workflows start in browser tools, finish in your ERP and accountant review.
Compliance checklist (Canada)
| Requirement | Practical check |
|---|---|
| Unique invoice / document number | No duplicates in FY; credit notes reference original |
| Supplier tax registration | GSTIN / VAT ID / ABN visible on PDF |
| Buyer details (B2B) | Legal name + billing address match PO |
| Tax rate per line | IGST inter-state vs CGST+SGST intra-state (India) |
| HSN/SAC or product codes | Match ERP master data |
| E-invoice / IRN (if mandated) | JSON + QR validated in portal — PDF alone insufficient |
| Immutable archive | Store approved PDF; do not edit in place |
Confirm current rules with CRA publications — not legal advice.
Step-by-step workflow
- Open Create Invoice and set the currency to CAD.
- Add your business name and GST/HST Business Number in From.
- Enter line items and set the GST/HST rate for the province.
- Add buyer details for sales of $150+, then download the PDF.
Common mistakes to avoid

- QR code present but IRN cancelled in portal
- Rent receipt without landlord PAN when required
- Payslip PDF missing employer registration fields
