Three Ways a Corporation Ends Up With Two
A short first year followed by a full one is the commonest. A corporation incorporated in October with a December 31 year-end has a three-month first year and then a full one, and both returns come due within six months of each other.
An approved change of year-end is the second, and a final period ending at dissolution is the third. In each case the two periods are separate tax years, and nothing about them being close together merges them.
| How it happens | The two periods | Returns owed |
|---|---|---|
| Incorporated part-way through a year | A short first tax year, then a full one | One for each |
| An approved change of year-end | A stub period at the changeover, then full years | One for each |
| Dissolved part-way through a year | A full year, then a short final period | One for each |
Two Deadlines Close Together Read as One
This is the practical failure. Two dates a few months apart look like one obligation, the later one gets filed, and the earlier year sits outstanding without anyone noticing, often for years.
An unfiled year does not expire. It stays open, invites a demand to file, and blocks a clearance certificate. The unfiled years checker is the page for working out whether this has already happened.
Two Returns Means Two Returns
Each tax year is its own return whatever its length, so two periods in one calendar year are two returns at $300.00 plus HST per tax year each. A three-month period is not a part-return and is not priced as one.
They can be prepared and transmitted together, which is how a catch-up is handled, and they are prepared oldest first because the closing balances of the first year open the second.
Why the Order Cannot Be Reversed
The second return opens from figures the first one establishes: retained earnings, the undepreciated balance on Schedule 8, the loss continuity. Filing the later year first means filing opening figures that have not been reported yet.
The retained earnings rollforward calculator gives the figure the second year has to open from.
Frequently Asked Questions
Can a corporation file two T2 returns in one year?
Yes, and it must where two tax years end close together. A short first year followed by a full one, an approved change of year-end and a final period at dissolution all produce two.
Do two returns cost twice as much?
Yes. Each tax year is its own return at $300.00 plus HST per tax year whatever the length of the period it covers.
Can both be filed at the same time?
They can be prepared and transmitted together. They are prepared oldest first, because the closing balances of the earlier year open the later one.
What if I only filed the later one?
The earlier year is outstanding. It does not expire, it invites a demand to file, and it blocks a clearance certificate until it is filed.
Is the deadline for the short period earlier?
No. The six-month rule runs from the day each period ends, so a short period gets the same six months as a full year.
