How to Calculate Corporate Taxable Income in Canada

Corporate income tax in Canada follows a dual rate system. That means if your corporate income falls below a certain level, you pay less income tax.  Read on for a basic overview of taxable corporate income in Canada.

What is a permanent establishment?

If your corporation isn't based in Quebec or Alberta, but you have a permanent establishment there, you will have to file separately. A permanent establishment can be an office, branch, oil well, farm, timberland, workshop, or other forms of activity.  If an employee, broker or agent does business for you in a certain place, it's a permanent establishment if either of the following is true:

     
  • The employee or agent has general authority to contract for the corporation.
  •  
  • The employee or agent regularly receives orders and fills them from stock owned by the corporation.

If you work with a commission agent, broker, or similar agent, or you have an office you use just to buy merchandise, it is not a permanent establishment. Neither a subsidiary controlled corporation, nor a subsidiary controlled corporation engaged in trade or business, is considered a permanent establishment.  If you have no particular head office, your permanent establishment is the address listed on your incorporation documents.  Here are some more details on how the Income Tax Regulations define permanent establishment, in Regulation 400(2):

     
  • An insurance company has a permanent establishment wherever it is registered or licensed to do business.
  •  
  • If a corporation with a permanent establishment in Canada owns land in a province, that land is a permanent establishment.
  •  
  • A corporation has a permanent establishment if it uses substantial machinery or equipment in a particular place at any time during the tax year.

If your business is incorporated, you need to fill in the T2 income tax return. Check out the CRA document T4012 T2 Corporation - Income Tax Guide 2017 for instructions. The CRA administers all provincial and territorial corporate income tax, except for Quebec and Alberta.

What are federal and provincial tax liabilities for corporations?

Corporations pay tax at both the federal and the provincial/territorial levels. Each province and territory has its own rules for corporate income tax. If you have a permanent establishment in more than one province or territory, you need to fill out Schedule 5.  If you claim provincial or territorial credits or rebates, or pay taxes other than income tax, again, fill out Schedule 5. Here is some information about provincial and territorial corporate tax rates, except Quebec and Alberta.  To file corporate income tax in Quebec, go to the provincial website. Information is in French only. For Alberta, go to their provincial website.

British Columbia

British Columbia corporate tax rates are based on your overall income. The general tax rate for 2018 is 12.0%, and the lower rate is 2.0%.

What is a taxable income calculator?

Your best bet for figuring out your taxable corporate income is the CRA tool for your province or territory. You should be clear on your corporate earnings to determine your income tax bracket.  Do you qualify for the lower, small business rate in your region? Make sure your financial statements confirm that your corporate income falls within the limit to claim the standard deduction. Deductions for corporations vary across the country and are subject to frequent change.  Stick with reliable sources when it comes to identifying which deductions your corporation might claim. Check your local government website frequently. Whenever possible, seek the advice of a finance, legal or tax professional.
