Definition of a Tax Invoice

A tax invoice is a document issued by a seller to a buyer that records the details of a taxable transaction. It includes information such as the amount payable, applicable taxes, and seller details. In Canada, tax invoices are essential for businesses registered for goods and services tax (GST) and harmonized sales tax (HST), as they provide proof of tax collection and facilitate input tax credit claims.

For example, a business selling consulting services in Ontario must issue a tax invoice that includes the 13 percent HST charged on the total service cost.

Purpose of a Tax Invoice in Business Transactions

A tax invoice serves multiple functions in financial and tax compliance, including:

• Recording taxable transactions for businesses and individuals.
• Ensuring compliance with GST/HST regulations set by the Canada Revenue Agency (CRA).
• Allowing businesses to claim input tax credits on purchases.
• Providing transparency in financial dealings between buyers and sellers.
• Supporting accounting and auditing processes for tax reporting.

GST/HST Thresholds for Tax Invoices

• For purchases over 150 dollars, the invoice must include a detailed breakdown of the taxable amount and tax rate applied.

Digital and Paper Invoices
