Best Practices and Common Mistakes to Avoid with Ontario Annual Filings

Even with the best intentions, many Ontario corporations struggle with their annual filing obligations. Some business owners find themselves scrambling at the last minute, while others miss deadlines entirely, often because of simple oversights or misunderstandings.
This guide highlights the most common pitfalls businesses face with their Ontario annual returns and provides practical strategies to ensure your corporation stays compliant year after year.
Common Mistake #1: Confusing Annual Returns with Tax Filings
Perhaps the most frequent misunderstanding stems from the pre-2021 system, when Ontario annual returns were filed alongside corporate tax returns.
What Goes Wrong
Many business owners still believe:
- Their accountant handles the annual return as part of tax preparation
- Filing their T2 corporate tax return satisfies the annual return requirement
- Annual returns are related to financial performance or tax obligations
Since the 2021 changes, this confusion has led countless corporations into default status.
Best Practice Solution
Clearly separate these two obligations in your compliance planning:
- Create distinct calendar entries for tax filings and annual returns
- Have an explicit conversation with your accountant about who’s responsible for annual returns
- Remember that annual returns are due within six months after your fiscal year-end, which may not align with tax deadlines
- Understand that annual returns confirm corporate information, not financial data
If you’re working with professional advisors, obtain written confirmation of exactly which filings they’ll handle and which remain your responsibility.
Common Mistake #2: Missing the Filing Deadline
The six-month post-fiscal-year deadline catches many corporations off guard, especially those accustomed to other compliance timelines.
What Goes Wrong
Businesses frequently miss deadlines because:
- They don’t have a system to track corporate compliance dates
- The responsibility for filing isn’t clearly assigned to anyone
- They confuse the annual return deadline with other corporate deadlines
- They don’t allow enough time to gather required information
Best Practice Solution
Implement a proactive deadline management system:
- Create a corporate compliance calendar marking all key dates
- Set multiple reminders at 90, 60, and 30 days before the deadline
- Assign specific responsibility for completion to a team member or external professional
- Consider filing early rather than waiting until the last minute
- If using the paper filing method, allow extra time for mailing and processing
Many law firms and corporate service providers offer compliance calendar services that automatically track these deadlines for you.
Common Mistake #3: Not Having Proper Access to the Ontario Business Registry
With the launch of the Ontario Business Registry in 2021, many corporations struggle with the technical aspects of filing.
What Goes Wrong
Common access issues include:
- Not having the company key required to access the corporation’s profile
- Losing or forgetting the company key
- Not creating a ServiceOntario account in advance
- Technical difficulties with the online system near filing deadlines
Best Practice Solution
Establish your online access well before filing is due:
- Request your company key immediately if you don’t have it
- Store your company key securely where authorized individuals can access it
- Create and test your ServiceOntario account in advance
- Save login credentials in a secure but accessible location
- Consider authorizing multiple individuals to have access in case of absences
If you anticipate access issues, consider using an authorized service provider who can file on your behalf without requiring your company key.
Common Mistake #4: Submitting Incomplete or Inconsistent Information
The annual return must accurately reflect your corporation’s current information, consistent with what’s already on record with the Ministry.
What Goes Wrong
Returns are frequently rejected because:
- The information doesn’t match what’s currently on file with the Ministry
- Required fields are left incomplete
- Director information is outdated or inconsistent
- The registered office address is invalid (e.g., using a P.O. box)
- The filing attempts to make changes that require a separate Notice of Change
Best Practice Solution
Before filing, verify your current information:
- Obtain a Corporation Profile Report from the Ontario Business Registry
- Compare your records against the official profile
- File any required Notices of Change before submitting your annual return
- Ensure all mandatory fields are completed accurately
- Verify that addresses are complete and conform to Ministry requirements
Remember that the annual return should confirm information already on record, if something has changed, a separate Notice of Change may be required first.
Common Mistake #5: Assuming No Activity Means No Filing
Some corporations incorrectly believe that if they had limited or no business activity, they don’t need to file an annual return.
What Goes Wrong
This misunderstanding leads to default status when:
- Startup companies in pre-revenue stages skip filings
- Corporations winding down operations neglect final returns
- Holding companies with no active business assume they’re exempt
- Seasonal businesses file only in active periods
Best Practice Solution
Remember that all active corporations must file regardless of activity level:
- File annual returns even for dormant or holding companies
- Continue filing until a corporation is officially dissolved
- Maintain compliance during startup phases and wind-down periods
- Include annual returns in your routine even during slow business cycles
If you truly no longer need the corporation, consider formally dissolving it rather than allowing it to fall into default through non-filing.
Common Mistake #6: Not Keeping Proof of Filing
Once the annual return is filed, many corporations fail to maintain adequate records of their compliance.
What Goes Wrong
This lack of documentation creates problems when:
- There’s a dispute about whether filing occurred
- The corporation needs to demonstrate compliance for due diligence
- Directors need to verify their obligations were met
- The corporation changes management or professional advisors
Best Practice Solution
Implement proper record-keeping practices:
- Save confirmation receipts from online filings
- Print or download the confirmation page immediately after submission
- Store a copy of each annual return in your corporate minute book
- Maintain a compliance log showing filing dates and confirmation numbers
- Periodically check your status in the Ontario Business Registry
Ontario law actually requires that a copy of the most recent annual return be kept at the corporation’s registered office, so proper record-keeping isn’t just good practice, it’s a legal requirement.
How Ontario’s Requirements Compare to Other Provinces
Understanding how Ontario’s system differs from other Canadian jurisdictions can help multi-jurisdiction businesses manage their compliance more effectively.
Key Differences to Note
Deadline Structure:
- Ontario: 6 months after fiscal year-end
- Federal: 60 days after incorporation anniversary
- BC & Alberta: 1-2 months after incorporation anniversary
- Quebec: Within first 6 months of calendar year
Government Filing Fees:
- Ontario: No fee for direct filing
- Federal: Approximately $12 (online)
- BC: Approximately $43
- Alberta: No direct government fee, but must file through registry agents
Enforcement Timelines:
- Ontario: No specific grace period; dissolution typically after 1-2 years of non-filing
- Federal: Dissolution after 2 consecutive missed years
- BC: Dissolution after 2 consecutive missed years
- Alberta: Approximately 18 months before dissolution
If your corporation operates in multiple jurisdictions, create a separate compliance tracker for each province’s requirements, as the deadlines and processes vary significantly.
Technological Solutions for Compliance Management
In today’s digital world, technology can significantly simplify the compliance process.
Effective Tools and Approaches
Corporate Record-keeping Software:
