Starting a corporation in Ontario is an exciting step toward building your business dream. But once the paperwork is done and your company is up and running, there’s one critical obligation you must never overlook: filing your Annual Return.
This isn’t just a formality. If you fail to file it, the government can dissolve your corporation, even if you’re still operating and making money. In this guide, we’ll walk you through what the Annual Return is, how and when to file it, and how to avoid putting your business at risk.
What Is an Annual Return in Ontario?
An Annual Return is a legal requirement for corporations in Ontario. It’s a yearly update to the government about your corporation’s basic information, such as:
- Corporation name
- Registered office address
- Names and addresses of directors
This is not a tax return—you still need to file your taxes separately with the CRA (Canada Revenue Agency). The Annual Return is part of your corporate compliance obligations under the Ontario Business Corporations Act (OBCA).
Who Needs to File an Annual Return?
The Annual Return applies to:
- All Ontario corporations, regardless of size or whether the business is active or inactive.
- Both for-profit and non-profit corporations.
It does not apply to:
- Sole proprietorships
- General partnerships
- Federally incorporated businesses (they have different filing obligations)
When Is the Annual Return Due?
Your Ontario Annual Return is due within 6 months after the end of your fiscal year.
📌 Example:
If your corporation’s fiscal year ends on December 31, then your Annual Return must be filed no later than June 30 of the following year.
This deadline repeats every year. Missing it even once can lead to consequences..

- Your corporation’s name becomes available to others.
- You may have to start over from scratch or pay to reinstate the corporation (a lengthy and expensive process).

❓ Frequently Asked Questions (FAQ)
Is the Annual Return the same as filing taxes?
No. The Annual Return is separate from your corporate income tax return. It’s about updating your corporation’s information with the provincial government.
What happens if I miss the deadline by a few days?
Technically, your corporation can be dissolved at any point after the 6-month deadline. While there might be a short grace period, it’s risky to rely on it.
Can I file my Annual Return by mail or in person?
Currently, Ontario requires Annual Returns to be filed online via the Ontario Business Registry
Can someone else file it for me?
Yes. A lawyer, accountant, or authorized representative can file it on your behalf—just ensure they have your Corporation Key and necessary access.
What if my corporation is inactive or has no income—do I still need to file?
Yes. Even if your business is inactive or not making money, you must file the Annual Return every year until the corporation is officially dissolved.
