You just incorporated. Congrats! Somewhere between the bank account and the business cards, someone asked, “What’s your fiscal year-end?” and you blanked. It’s not a trick question, but it’s one of those early choices that affects your deadlines, your cash flow and even your tax for years. And changing it later isn’t automatic.

Which Fiscal Year-End Should Your Corporation Choose?
A corporation can choose any year-end, as long as the first fiscal year is no longer than 53 weeks from the date you incorporated. Many small businesses pick December 31 for simplicity, but a year-end that falls in your slow season, or that gives you a bonus-deferral and cash flow advantage, is often smarter. Once chosen, you need CRA approval to change it.
Fiscal Year-End vs the Calendar Tax Year
- Individuals (including sole proprietors) use the calendar year: January 1 to December 31.
- Corporations use a fiscal year: any 12-month period you choose, ending on your year-end.
So if your company’s year ends June 30, your 2026 T2 covers July 1, 2025 to June 30, 2026. Your personal T1 still covers the calendar year. That gap is where a lot of the planning comes from. More on how the two returns differ: T1 vs T2.
CRA Rules: The 53-Week Limit and Your First Year-End
- Your first fiscal period can’t be longer than 53 weeks from incorporation.
- It can be shorter. Incorporate in October and pick December 31? Your first year is just a few months long.
- A short first year means a T2 is due sooner and the small business limit is prorated for that period.
- You “choose” your year-end by filing your first T2 with that year-end. There’s no separate form.
How to Choose: Seasonality, Bonus Deferral, Workload and Cash Flow
| Factor | What to think about |
| Seasonality | Pick a year-end in your quiet season. Counting inventory in your busiest month is miserable |
| Bonus deferral | The company can deduct a bonus accrued at year-end if it’s paid within 179 days, so you can push personal tax into the next calendar year |
| Accountant workload | Non-December year-ends often get more attention and faster turnaround |
| Cash flow | Corporate tax is due 2 or 3 months after year-end. Pick a year-end so that payment doesn’t hit when cash is tight |
| Industry norms | Retailers often avoid December. Construction may prefer a winter year-end |
| Simplicity | December 31 lines up with T4s, T5s and your personal return |
December 31 vs a Non-Calendar Year-End: Pros and Cons
| Â | December 31 | Non-calendar (e.g., March 31, June 30) |
| Easy to understand | Yes | Takes some getting used to |
| Lines up with T4/T5 and personal tax | Yes | No |
| Bonus deferral planning | Limited | Often better |
| Accountant availability | Busiest season | Usually quieter |
| Good for retail or holiday-heavy businesses | Often not | Often yes |
How Your Year-End Sets T2, Tax Payment and Instalment Deadlines
| Item | Deadline |
| T2 corporate return | 6 months after year-end |
| Balance of tax owing | 2 months after year-end (3 months for many CCPCs claiming the small business deduction) |
| Monthly or quarterly instalments | Based on your fiscal year |
| Annual GST/HST return (annual filers) | 3 months after year-end |
| T5 slips for dividends | February 28 (calendar-based, regardless of year-end) |
Notice that tax is due before the T2 is due. That trips up a lot of new owners. Keep our tax deadlines guide handy, and see what happens if you file a corporate return late.
Sole Proprietors and Partnerships: Why Most Must Use December 31
If you’re not incorporated, you generally must use a December 31 year-end. There’s an “alternative method” that allows a different year-end with extra calculations, but it’s rarely worth it today. Just one more difference to weigh if you’re thinking about switching from sole proprietor to corporation.
Changing Your Fiscal Year-End: CRA Approval Required
A corporation can’t just pick a new year-end next year. You need to:
- Send CRA a written request explaining a valid business reason (for example, aligning with a new parent company, or a change in business cycle).
- Wait for approval before filing a T2 with the new year-end.
“To save tax” alone isn’t a valid reason. Some events automatically create a new year-end, such as an acquisition of control or an amalgamation.
How to Find Your Corporation’s Fiscal Year-End
- Your last T2 return or Notice of Assessment
- My Business Account under corporate income tax
- Your financial statements
- Ask your accountant
Note that your BC annual report date is your incorporation anniversary, not your fiscal year-end. They’re different things.
FAQ: Corporate Fiscal Year-End
What is the filing deadline for a T2 corporation return?
Six months after your fiscal year-end. Tax owing is due 2 or 3 months after year-end.
Is June 30 a good fiscal year-end?
It can be. It’s popular for bonus planning and avoids the December crunch. It depends on your business cycle.
Can my first fiscal year be shorter than 12 months?
Yes. It just can’t be longer than 53 weeks.
Does my fiscal year-end affect GST/HST filing?
Yes. Annual GST/HST filers use their fiscal year, and quarterly or monthly periods are usually based on it.
What is Canada’s tax year for individuals?
January 1 to December 31.
