1. Introduction

Canada operates a federal tax system administered primarily by the Canada Revenue Agency (CRA). Businesses may also have obligations to provincial tax authorities depending on where they operate.

Canadian taxation generally consists of:

• Corporate Income Tax

• Personal Income Tax

• GST/HST

• Provincial Sales Tax (PST/QST in some provinces)

• Payroll Taxes

• Customs Duties

• Excise Taxes

Canada also maintains an extensive network of tax treaties to reduce double taxation.

2. Main Tax Authority

The primary authority is the Canada Revenue Agency (CRA).

The CRA administers:

• Corporate taxes

• Individual taxes

• GST/HST

• Payroll deductions

• Tax audits

• Tax credits

• Business numbers (BN)

• Electronic filing services

Businesses generally register for a Business Number (BN), with separate program accounts for GST/HST, payroll, and corporate tax as needed.

3. Business Structures

Common legal entities include:

Sole Proprietorship

• Simplest form

• Income taxed personally

• Unlimited liability

Partnership

Profits generally flow through to partners.

Corporation

Most common for medium and large businesses.

Advantages:

4. Business Registration

Typical registration steps include:

• Incorporate federally or provincially

• Obtain a Business Number (BN)

• Register for GST/HST (if required)

• Register payroll accounts

• Open a corporate bank account

Additional registrations may be required depending on industry and province.

5. Corporate Income Tax

Canadian corporations file a T2 Corporation Income Tax Return. Federal corporate income tax is complemented by provincial or territorial corporate tax, with rates varying by jurisdiction. Eligible Canadian-controlled private corporations (CCPCs) may qualify for reduced rates on certain active business income.

Corporate tax is generally calculated as:

Taxable Income
× Applicable Tax Rate
= Corporate Tax Payable

6. GST/HST

Canada imposes a federal Goods and Services Tax (GST) of 5%. Some provinces combine the federal GST with provincial sales tax into a Harmonized Sales Tax (HST), while others maintain separate provincial sales taxes (PST) or Quebec Sales Tax (QST). Businesses may need to register, collect tax, claim input tax credits (ITCs), and file periodic returns.

Businesses collect GST/HST on sales and may recover eligible GST/HST paid on business purchases through ITCs.

7. Provincial Sales Taxes

Some provinces levy additional sales taxes.

Examples include:

• Ontario — HST

• British Columbia — GST + PST

• Saskatchewan — GST + PST

• Quebec — GST + QST

• Alberta — GST only

Sales tax obligations depend on the province where supplies are made.

8. Payroll Taxes

Employers must:

• Register payroll accounts

• Withhold employee income tax

• Deduct Canada Pension Plan (CPP) contributions

• Deduct Employment Insurance (EI) premiums

• Remit payroll deductions to the CRA

Payroll remittance frequency depends on the employer's classification and withholding amounts.
