Every fiscal year-end, and the filing month it creates
Reviewed by EverStone CPA · August 2026
Quick answer: Your T2 corporate return is due six months after your fiscal year-end — so a December year-end files by June, a March year-end by September. The table below applies that rule to all twelve months. The trap is that the tax payment is generally due earlier than the return, which is why “when is my T2 due” is really two questions — our T2 deadline guide and calculator split them properly.
Find your year-end
| Fiscal year-end | T2 filing deadline (6 months later) |
|---|---|
| January 31 | July 31 |
| February 28/29 | August 28/29 |
| March 31 | September 30 |
| April 30 | October 31 |
| May 31 | November 30 |
| June 30 | December 31 |
| July 31 | January 31 |
| August 31 | February 28/29 |
| September 30 | March 31 |
| October 31 | April 30 |
| November 30 | May 31 |
| December 31 | June 30 |
Where a deadline lands on a weekend or holiday the CRA’s adjustment rules apply — see the deadlines page. A year-end on a day other than month-end shifts the arithmetic accordingly.
The payment comes before the paperwork
Filing six months out lulls people. The balance owing is generally due earlier than the return itself — and interest runs from the payment deadline, not the filing one. Which deadline applies to your corporation depends on its circumstances; the T2 deadline guide walks through it, and the calculator gives you both dates from your year-end.
Choosing a year-end, if you still can
New corporations choose their first year-end, and the choice sets this clock permanently — plus quieter things, like whether your filing season lands in your busy season. The considerations are covered in choosing your corporate year-end; it is a five-minute decision that deserves ten.
What we do with this
Clients’ deadlines are tracked from their year-end — filing, payment and instalments — so none of these dates is the owner’s job to remember. That is most of what “year-round” means: book a consult and stop carrying the calendar in your head.
