Taxation Introduction
Taxation Info-Guide
The Taxation Info-Guide is designed to help you navigate through the federal and provincial government programs, services and regulations related to taxation that may apply to individuals starting or operating a business in Ontario.
Business Number - BN
The Business Number is a numbering system that simplifies and streamlines the way businesses deal with the federal government. It is based on the idea of one business, one number. The BN includes the four major Canada Revenue Agency (CRA) business accounts - corporate income tax, import/export, payroll deductions and goods and services tax/harmonized sales tax (GST/HST).
Sales Taxes
GST/HST
The GST is a tax that applies at a rate of 5% to the supply of most goods and services in Canada. Three provinces (Nova Scotia, New Brunswick, and Newfoundland and Labrador) harmonized their provincial sales tax with the GST to the HST.
Vendor Permits and the Retail Sales Tax
Individuals and companies who sell goods or services that are taxable under the Ontario retail sales tax (also known as 'provincial sales tax' or 'PST') require a Vendor Permit. This document will explain this sales tax.
