December 31 Year-End vs a Non-Calendar Year-End
What the fiscal year-end date changes about a nil T2, what it does not, and why December 31 is a convention rather than a rule.
The Date Moves the Deadline, Not the Return
A quiet year is the same piece of work whenever it ends. The year-end decides when the return is due and when the records are wanted, and that is the whole of its effect on a nil filing. It does not change which schedules attach, who signs, how the return is transmitted or what it costs.
December 31 is worth no more and no less than any other date. It is common because it lines up with the calendar most people already keep, not because anything in the rules prefers it, and a corporation that picked August 31 is in exactly the same position six months after August 31.
The Comparison, Row by Row
Prices checked November 4, 2026. Both figures are our own published fee.
| Item | December 31 Year-End | A Non-Calendar Year-End |
|---|---|---|
| Our published fee for a quiet year | $300.00 plus HST per tax year | $300.00 plus HST per tax year |
| A second quiet tax year | $300.00 plus HST per tax year | $300.00 plus HST per tax year |
| The tax year ends | December 31 | The date the corporation chose |
| The T2 is due | June 30 the following year | Six months after that year-end |
| Working the due date out | June 30, with nothing to count | Six months counted to the same day number in the later month |
| When the records are wanted | Early in the new calendar year, with everything else dated December 31 | At whatever point in the year the chosen date falls |
| What sets the date in the first place | The first T2 return filed. Nothing assigns one at incorporation | The first T2 return filed. Nothing assigns one at incorporation |
| The first tax year | From incorporation to that year-end, 53 weeks at most | From incorporation to that year-end, 53 weeks at most |

| Filing route and confirmation | Transmitted electronically, CRA confirmation emailed within 3 business days | Transmitted electronically, CRA confirmation emailed within 3 business days |
Four rows differ and six do not. The year-end moves the dates and nothing else. What sets it, the 53-week limit on the first one, the approval needed to change it and the fee are the same on any date.

Nothing Assigns You a Year-End
The date is a decision rather than a default:
- A corporation picks its own fiscal year-end. There is no default and nothing is allocated at incorporation.
- The articles of incorporation do not set it either. What sets it is the first T2 return filed.
- A first tax year runs from the date of incorporation to the chosen year-end and may not exceed 53 weeks, which is 371 days counting the day of incorporation.
- Once the first return is filed the date is on the record and it recurs annually.
- Changing it afterwards needs the written approval of the Canada Revenue Agency.
- A short year does not get an early deadline. The six months are counted from the day that short year ends.
A year-end that does not match the one on the record gets the transmission rejected. Where no return has ever been filed the date is still unsettled, and the first return filed is what settles it.
The nil T2 deadline calculator dates the return from any year-end, the 53-week first tax year checker tests a proposed first year-end, the year-end change approval checker takes the question of changing it, and the complete guide to choosing and changing a fiscal year-end sets out the rest.

A corporation incorporated in September that picked August 31
Its first tax year runs from the September incorporation date to the following August 31, which is inside the 53-week limit, so the date is available. That first return is due the following February 28 or 29, six months after August 31, and every year after it runs on the same cycle. Nothing about the quiet year is different from a December 31 corporation: the same schedules where anything sits on the books, the same Form T183CORP, and $300.00 plus HST per tax year. The figures here illustrate how the rules apply and are not drawn from a client file.
Frequently Asked Questions
Does the year-end change what a nil return costs?
No. The fee is $300.00 plus HST per tax year on any year-end. The date moves the deadline, not the price.
Is December 31 the default year-end?
No. December 31 is a convention rather than a rule. Nothing is allocated at incorporation and the articles of incorporation do not set a date either.
Then what sets my year-end?
The first T2 return filed. From then on the date is on the record and it recurs annually.
When is the return due on a December 31 year-end?
June 30 the following year, which is simply the six-month rule applied to December 31.
How do I work out the date on another year-end?
Count six months to the same day number in the later month. An August 31 year-end falls on the last day of February, because there is no thirty-first of February.
Can I still pick my year-end?
Only until the first return is filed. If no return has ever been filed the date is still unsettled, and the first one filed settles it.
How long can the first tax year be?
Up to 53 weeks, which is 371 days counting the day of incorporation. A year-end chosen further out than that is not available, so the first year has to end earlier.
Can I change the year-end later?
Changing it needs the written approval of the Canada Revenue Agency. It is not something a corporation does by filing on a different date.
Does a short year get an earlier deadline?
No. The six months are counted from the day the short year ends, exactly as they are for a full one.
What happens if I file on the wrong year-end?
A year-end that does not match the one on the record gets the transmission rejected, which is one of the more common reasons a return does not go through first time.
Is a December 31 year-end simpler to keep?
It lines up with the calendar most people already keep, so the records are wanted alongside everything else dated December 31. That is convenience, not a rule, and it changes nothing about the return.
Do the schedules depend on the year-end?
No. The schedules follow what sits on the corporation’s books, not the date the year ended.
Does a non-calendar year-end make a nil return harder to file?
No. The work is the same and the route is the same. Only the dates differ.
Which year-end should a new corporation pick?
That is a decision for the corporation and its own circumstances. What matters here is that the choice is made before the first return goes in, and that it sits inside the 53-week limit.
Which tool should I run first?
The nil T2 deadline calculator, which dates the return from any year-end you give it.
