One Annual Return for Each Tax Year
The Ontario annual return is tied to the tax year-end, so one falls due for each tax year the corporation exists. Missing a year does not remove it: the next year adds its own, and they accumulate.
An annual return is not a tax filing, so having no income does not excuse it. A dormant corporation confirms its directors and its registered office every year in exactly the way an active one does.
What a Missed Year Actually Causes
| Missed | What it creates | What it does not create |
|---|---|---|
| One annual return | A registry record that is out of date | Any tax |
| Several annual returns | A corporation the registry treats as abandoned | Any tax |
| Enough of them | A registry that may dissolve or strike the corporation | Dissolution for tax purposes, and it cancels no outstanding T2 return |
The involuntary dissolution risk checker takes being struck, and the corporate revival requirement checker takes what happens after it.
The Registry Count and the Tax Count Are Separate
The two trails are independent. A corporation can be fully current on its T2 filings and still be struck from its registry, and it can be in good standing at the registry while owing ten years of T2 returns.
So this count answers one of the two questions. The unfiled years checker answers the other.
Frequently Asked Questions
How many annual returns do I owe?
One for each tax year since the last one filed. The calculator above counts the tax year-ends that have passed.
Does a missed annual return create tax?
No. It creates a registry record that is out of date, and after enough missed years a corporation the registry treats as abandoned.
Does this tell me whether my T2 returns are filed?
No. The two trails are independent, so a clean registry record says nothing about the tax years and the reverse is also true.
What does the registry do after several missed years?
It can strike the corporation, dissolving it involuntarily. That ends the corporation’s legal existence and settles nothing at all on the tax side.
Is there a charge for each missed annual return?
The registry’s response is to strike the corporation rather than to charge it, which is a blunter consequence than a sum of money and has a different cure.
Does filing the outstanding ones put it right?
While the corporation is still on the register, yes: filing what is outstanding brings the record up to date. Once it has been struck, revival is the step that comes first.
Does this change what the Canada Revenue Agency is owed?
No. Tax years are counted on their own, and an unfiled T2 stays unfiled whatever the registry record happens to show.
I do not know when the last one was filed.
The registry record settles it, and it is the corporation’s own record to check. The calculator counts from the date you enter, so an uncertain date gives an uncertain count.
Does a change of directors count as one?
No. They are separate filings, and making one does not discharge the other even in the same year.
Is the count the same as the number of unfiled T2 returns?
Only by coincidence. One of each falls due for a tax year, but they are filed in different places, and a corporation is often current in one trail and years behind in the other.
