Key Features of a GST-Compliant Invoice in Canada
To ensure your invoices meet Canadian legal standards, especially for Goods and Services Tax (GST) or Harmonized Sales Tax (HST), they must include specific mandatory information. If your business is a GST/HST registrant (typically if your taxable supplies exceed $30,000 in a year), you must include your 15-character Business Number (BN) on all invoices. This BN, structured as 123456789RT0001, identifies your GST/HST account.
Essential elements for a compliant invoice include:
- Your business name and address.
- The client's name and address.
- A unique invoice number and the invoice date.
- A clear description of goods or services, including quantity and unit price.
- The subtotal before taxes.
- The applicable GST/HST rate(s) and the tax amount shown separately.
- The total amount due, including all taxes.
- Payment terms and due date.
For invoices of $150 or more, including your GST/HST registration number is crucial for your clients to claim Input Tax Credits (ITCs).
