Canadian Invoice Requirements

Overview of Canadian Invoice Requirements

In Canada, businesses must comply with specific invoicing requirements set by the Canada Revenue Agency (CRA) for tax purposes and the Canada Border Services Agency (CBSA) for customs declarations. Proper invoicing ensures compliance with federal and provincial tax laws, facilitates customs clearance, and supports accurate financial reporting.

Mandatory Information on Invoices

For GST/HST Purposes (CRA Requirements)

All invoices must include:

• Business information: Your business name, address, and GST/HST registration number (if applicable)
• Customer details: Client's name and address
• Invoice specifics: Unique invoice number, date of issue, and clear due date
• Transaction details: Itemized description of goods/services, quantities, unit prices, and totals
• Tax breakdown: Total amount before taxes, GST/HST amount charged, and applicable tax rate(s)
• Payment terms: Accepted payment methods and any late payment penalties

For harmonized sales tax (HST), businesses must show the combined rate rather than separating federal and provincial components. [

For Customs Declarations (CBSA Requirements)

The CBSA requires commercial invoices or completed Canada Customs Invoice (Form CI1) with these essential elements:

• Vendor information: Seller's name and address
• Shipment details: Date of direct shipment to Canada, mode of transportation, and place of origin
• Parties involved: Consignee and purchaser names/addresses
• Commodity description: Detailed specifications including kind of packages, marks/numbers, and general description
• Pricing information: Currency of settlement, unit price, total amount, and invoice total
• Weight details: Both net and gross weight
• Country of origin: Where goods were grown, produced, or manufactured

E-invoicing Requirements

While B2B and B2C e-invoicing remains optional for most Canadian businesses, federal government departments and agencies must receive e-invoices. The CRA encourages electronic filing through its online portal (My Business Account).

Accepted Formats

• XML-based formats are standard, including:
  • Universal Business Language (UBL)
  • PEPPOL BIS Billing 3.0
• No central hub exists; businesses typically use networks or access point providers

Digital Archiving

E-invoices must be archived for a minimum of six years in a format that allows for retrieval and inspection by the CRA if needed.

Tax-Specific Requirements

Canada has multiple sales taxes that may apply depending on the province and transaction type:

Goods and Services Tax (GST)

• Standard federal rate: 5%
• Applies to most goods and services
• Provinces without PST: Alberta, Northwest Territories, Nunavut, and Yukon

Harmonized Sales Tax (HST)

• Combined GST/PST rate: 13-15% depending on province
• Applies in: New Brunswick, Newfoundland and Labrador, Nova Scotia, Ontario, and Prince Edward Island

Provincial Sales Tax (PST)

• Rates vary by province (e.g., 7% in British Columbia, 6% in Saskatchewan)
• Applies in provinces without HST

Quebec Sales Tax (QST)

• Rate: 9.975%
• Functions similarly to PST but is closely harmonized with GST

Customs and Import Invoices
