Who is required to file a tax return in Canada and why is it mandatory?

Every year at T2inc.ca, we encounter business owners who either forget or postpone filing their T2 corporate tax returns, often due to misunderstandings about their tax obligations. Some mistakenly believe they don't have to file if their business hasn't earned any income. Others believe they can delay filing without facing immediate consequences.
The truth, however, is simple: every incorporated business in Canada must file a T2 Corporation Tax Return annually, regardless of its level of activity. This is a legal requirement with no exceptions.
Unfortunately, many business owners realize too late that failure to file will result in penalties, interest, and unnecessary complications with the Canada Revenue Agency (CRA). But why exactly does the CRA require this filing, and are there any exceptions?
Here's what you need to know.
Do I have to file a T2 corporate tax return each year?
Yes, you must. Every corporation in Canada, without exception, must file a T2 corporate income tax return each year.
Unlike a sole proprietorship, a corporation is a legal entity separate from its owners. Therefore, it must report its income, expenses and assets separately to the Canada Revenue Agency (CRA), even if it didn't conduct any business activities during the year.
A mandatory obligation under Canada’s Income Tax Act
The Income Tax Act (ITA) requires all corporations registered in Canada to file a T2 return annually, regardless of their financial situation.
You must file a T2 corporate tax return even if:
- Your business is inactive and has had no commercial activity.
- Your corporation had no income or expenses during the year.
- Your company does not owe any tax through credits or deductions.
Even if you are not making a profit, your business must confirm to the CRA each year that it is still in compliance. To learn more about business tax returns, find out what a T2 return is in our guide for small business owners in Canada.
Inactive corporations must also file a T2 return
A common misconception among owners of inactive corporations is that if their company has not generated any income, they are exempt from filing. This isn't true.
However, an incorporated company remains a legal entity, even if it is inactive. Until it is officially dissolved, it must declare its status annually to the Canada Revenue Agency (CRA).
Risks of not filing a T2 return in Canada
If you don't file your T2, the CRA won't know whether your business is inactive, active or abandoned. This failure can have several consequences:
- Notices and reminders from the CRA for failure to file.
- Penalties and interest even if no tax is due.
- Classification of your business as inactive, with the risk of administrative dissolution.
Every year, countless business owners realize too late the importance of filing a timely T2, often after receiving warning letters. The longer you delay, the more complications arise. Avoid common mistakes by reading our article on the most common mistakes business owners make when filing corporate taxes.

Closing your business doesn't exempt you from filing a final T2
Many business owners believe that ceasing operations automatically ends their tax obligations. However, until your corporation is officially dissolved, it remains legally active and must continue to file an annual corporate income tax return in Canada.
The Canada Revenue Agency (CRA) requires a final T2 return to formalize the closing of a business and ensure that all tax obligations have been met. This includes reporting the end of operations, reporting income and expenses for the last year, and paying any taxes due.
Failure to do so can result in liens, penalties for failure to file, and delays in the dissolution process. The company may even be considered still active by the CRA, which can lead to further administrative complications.
Therefore, before closing a company, it is essential to:
- File a final T2 return.
- Pay any outstanding taxes and declare any remaining tax liabilities.
- Submit required documents to CRA and provincial authorities.
Failure to follow these steps will unnecessarily prolong your company's legal existence and create avoidable administrative burdens.
Why does the CRA require a T2 return?
The Canada Revenue Agency (CRA) does more than collect taxes. Its role is also to monitor the activities of incorporated businesses to ensure fair taxation and prevent irregularities. For this reason, it requires the annual filing of the T2 return, even for companies with no tax liability.
1. Monitor all incorporated businesses (including non-residents)
All corporations registered in Canada are listed in the CRA's tax databases. The T2 form allows you to:
- Check whether a company is still active or inactive.
- Track its financial history over the years.
- Identify companies that are not meeting their tax obligations.
This requirement also applies to non-resident corporations operating in Canada.
2. Prevent tax evasion and fraud
Without a reporting requirement, some companies could hide income, avoid paying taxes, or take undue advantage of tax benefits.
The requirement to file a T2 each year enables the CRA to detect tax inconsistencies and ensure that all companies play by the same rules. It is also a tool to combat shell companies created solely for abusive optimization purposes.
3. Ensure compliance with other Canadian tax obligations
A T2 return is not just about corporate taxes. It also confirms the company's compliance with other tax obligations, including:
- Installment payments, if required.
- Filing of GST/QST returns, for companies registered for sales taxes.
- Reporting payroll deductions, if the company pays salaries.
By requiring businesses to file a T2, the CRA ensures that the entire tax system is working properly and that every business is doing its part to comply with Canada's tax laws.
Are there any exceptions to filing a T2 return?
In very rare cases, certain companies are not required to file a T2 return. These exceptions apply only to certain categories of corporations, such as:
- Crown corporations, owned by the federal or provincial government.
- Registered charities, recognized by the CRA.
- Certain municipal or aboriginal corporations that are exempt by law.
If your business is a registered small business, an inactive corporation, or a start-up, it's mandatory to file a T2 return, even if you have no income or taxes to pay. There are no exceptions.
The CRA requires this return to ensure that your business remains in good standing and meets its tax obligations, regardless of its financial situation. Learn more about the process of completing your corporate tax return.
