Types of Taxes in Canada:

Individuals and corporations in Canada are subject to many different tax regimes. To fully comprehend the tax system, becoming familiar with these many tax classifications is crucial. Canada’s primary tax categories are as follows:

  • Income Tax:

Most Canadians’ tax burden comes primarily from income tax. The tax rate rises in tandem with one’s income because it is progressive. Income tax is collected by both the federal government and individual provinces and territories. Income tax rates in the federal government change according to your tax bracket, and provincial and territorial governments set their rates.

  • 1.2 Goods and Services Tax (GST):

Most purchases made in Canada are subject to a national sales tax called the Goods and Services Tax. GST is a tax added to the retail price of taxable products and services at the current rate of 5%. The Harmonised Sales Tax (HST) is a hybrid of the GST and provincial sales taxes in some provinces.

  • 1.3 Provincial Sales Tax (PST):

The purchase or leasing of taxable goods and services in various jurisdictions is subject to a provincial sales tax. Some provinces have combined their sales tax with the GST to create the HST, while others have different PST rates and regulations.

Income Tax Obligations:

If you want to be in charge of your finances, you need to know what your income tax responsibilities are. Now I will explain some of the fundamentals of Canadian income tax:

  • 2.1 Taxable Income:

Earnings from all sources, such as a job, a business, investments, and so on, add up to “taxable income” at tax time. It is possible to lower one’s taxable income by using deductions and credits.

  • 2.2 Tax Brackets:

The tax system in Canada is multi-tiered and progressive. A different tax rate is applied to a different income level between the lowest and highest tax brackets. In Canada, the federal government, the provinces, and territories determine their tax rates and brackets.

  • 2.3 Deductions and Credits:

You can lower your taxable income and tax liability by taking advantage of deductions and credits. Common deductions include contributions to a Registered Retirement Savings Account (RRSP) or First Home Savings Account (FHSA), Medical Expenses, Donations, Childcare Expenses, and Student Loan Interest. Paying less in taxes is possible because of credits like the GST/HST credit and the Canada Child Benefit.

  • 2.4 Tax Payable:

This is the amount of tax owed based on your tax rate. The tax rate is a percentage based on your income bracket at the federal and provincial levels.

Filing Taxes in Canada:

Now that I’ve covered income tax fundamentals let me take you through the specifics of filing taxes in Canada.

  • 3.1 Tax Filing Deadlines:

Unless you or your spouse/partner are self-employed, the deadline to file your income tax return is April 30 of the following year. If that’s the case, you have until June 15 to file your taxes, but you should do so no later than April 30 to avoid late fees. Note that if this date falls on a weekend, it will be the next business day. For example, the deadline for personal income tax filing for 2023 is April 30th, 2024.

  • 3.2 Methods of Filing:

You can use tax preparation software to file your return electronically, hire a tax professional, or file a paper return by mail. Quicker and with immediate proof of receipt, electronic filing is the way to go. I recommend using Wealthsimple Tax as it’s simple and free!

  • 3.3 Benefits of Filing on Time:

If you’re due a refund, filing your taxes on time will speed up the process. You won’t have to worry about interest or late fees either. Maintaining compliance with tax laws requires prompt filing. Tax refunds typically take around 5 business days to hit your account with direct deposit from CRA or 15 days for a cheque in the mail.

Business Taxes in Canada:

Business owners and self-employed people must be aware of their unique tax responsibilities:

  • 4.1 Business Structure:

Your tax liabilities will change depending on whether you operate as a single proprietorship, a partnership, or a corporation. The reporting and taxation of income are subject to varying regulations depending on the organizational form.

  • 4.2 Business Expenses:

In most cases, you can deduct from your business income any costs you incurred explicitly to make a profit. Maintain accurate records of all business expenditures to claim deductions successfully.

  • 4.3 Sales Taxes:

Taxes on purchases and transactions, such as the Goods and Services Tax (GST) and the Harmonised Transactions Tax (HST), may need to be collected and filed by your business to the CRA. To prevent fines, it’s important to familiarise oneself with the sales tax legislation and register as required.

  • 4.4 Corporate Taxes

This is a tax on the profits of a corporation that generates revenue for a government. It is typically calculated as a percentage of the taxable income of a business.


The Canadian tax system is complex, but knowing its fundamentals will help you make sound decisions and stay in compliance. I believe you can better manage your finances and comply with your tax requirements if you have a firm grip on the various tax types, know your income tax obligations, and know how to submit taxes.
