What the Ontario Business Registry Is For
The Ontario Business Registry is the provincial system through which the annual return, address changes and director changes are filed. A corporation needs its Ontario corporation number and its registry access to use it.
It is not where tax is filed. The T2 goes to the Canada Revenue Agency, and the two trails are independent: a corporation can be fully current on its T2 filings and still be out of date at the registry.
What Goes to Which Body
| Filing | Filed with | Carries tax |
|---|---|---|
| The Ontario annual return | The Ontario Business Registry | No. It carries no tax and no payment |
| A change of registered office address | The Ontario Business Registry | No |
| A change of directors or officers | The Ontario Business Registry | No |
| The T2 corporate return | The Canada Revenue Agency | Yes, where there is tax to carry |
The annual return versus tax return checker separates the two filings, and the Ontario annual return versus the T2 sets them side by side.
Nothing in the T2 Prompts the Registry Filing
Until 2021 the Ontario annual return was filed alongside the T2, so one act covered both. Since October 2021 it is filed through the Ontario Business Registry instead.
Because the filing moved out of the T2, nothing in the corporate tax return now prompts an owner to do it. The prompt has to come from the owner or the adviser, which is the whole reason this checker exists.
Frequently Asked Questions
What is filed through the Ontario Business Registry?
The annual return, changes of registered office address and changes of directors or officers. The T2 is not: it goes to the Canada Revenue Agency.
What do I need to use the registry?
The corporation’s Ontario corporation number and its registry access. Without those, none of the filings can be made.
Is any of this included in nil T2 filing?
No. Registry filings are not part of nil T2 filing at $300.00 plus HST per tax year, and filing the T2 does not satisfy an annual return.
Does filing the T2 update the registry?
No. The two go to different bodies and neither carries anything to the other. A registry record stays exactly as it was until a registry filing changes it.
What goes wrong when the registered office address is stale?
Mail stops arriving anywhere anyone reads it. That includes the notice warning that the corporation is about to be struck for a missed annual return, which is the one letter an owner most needs to see.
A director has resigned. What do I file?
A change of directors, through the registry. It is its own filing, separate from the annual return, and it is reported nowhere on the corporate tax return.
Does a dormant corporation have to keep any of this current?
Yes. The registry asks who the directors are and where the office is, and those answers are owed whether or not the corporation traded in the year.
Who is allowed to make these filings?
Someone with authority to bind the corporation, which in practice means a director or an officer. An adviser can file on instructions, but the authority still comes from inside the corporation.
Does the registry pass anything to the Canada Revenue Agency?
No. The two keep separate records and neither reports a filing status to the other, so being current in one place proves nothing about the other.
Is a numbered company treated any differently?
No. A number instead of a name changes nothing about which filings are owed or when they fall due.
