Why year-end matters

Your corporate year-end is more than an admin choice. It sets your corporate tax deadlines, drives when your accounting needs to be cleaned up, affects cash flow planning for taxes, and can make owner bonus and dividend planning either smooth or painful.

This post explains (1) the rules you must follow, and (2) the practical factors to consider so you choose a year-end that fits your business.

1) CRA rules and tax requirements

A) Your tax year is your fiscal period

For a corporation, the tax year is the corporation’s fiscal period. The key rule: a fiscal period cannot be longer than 53 weeks (371 days).

B) Choosing the first year-end (new corporations)

A new corporation can generally choose any year-end date, as long as its first fiscal period is not more than 53 weeks from the date of incorporation (or from the date it was formed on an amalgamation).

Example:

If you incorporated your business on November 24, 2025, you can choose any date between the incorporation date and November 30, 2026 (53 weeks), as your tax and fiscal year end.

C) Filing deadline (T2)

Your corporation generally has to file its T2 return within 6 months after the end of its fiscal period.

D) Payment deadlines (balance-due day and instalments)

Do not confuse the filing deadline with when tax is due. Corporations typically:

• pay instalments during the year (usually monthly)
• then pay the remaining balance by the balance-due day (generally 2 months after year-end)
• some CCPCs may qualify for a 3-month balance-due day (if conditions are met)

Some eligible small CCPCs can pay quarterly instalments instead of monthly if they meet CRA eligibility conditions (including being a CCPC, having a perfect compliance history, and meeting certain taxable income and taxable capital thresholds).

Key deadlines at a glance

Item	Typical deadline	Notes
T2 filing deadline	6 months after fiscal year-end	Applies to most corporations
Balance-due day	2 months after fiscal year-end	General rule under the Income Tax Act
Balance-due day (eligible CCPC)	3 months after fiscal year-end	Only if CCPC meets conditions
Instalments	Usually monthly during the tax year	Some eligible CCPCs can pay quarterly

E) Changing a year-end later

Generally, your corporation’s fiscal period stays the same from year to year. To change a fiscal year-end, CRA generally expects you to request approval (typically by writing to your tax services office with the reasons and the effective date).

2) Practical factors to consider (the decision framework)

The ‘best’ year-end is the one that matches how your business actually runs. Here are the factors that usually matter most.

Seasonality and operational workload: Choose a date after your busiest season, when your team can pull records together and inventory counts (if any) are realistic.

Cash flow and when taxes become due: Tax can be due 2-3 months after year-end. Avoid a year-end that makes your tax payment land in your slowest cash period. Although, you pay tax instalments during the year.

Owner-manager bonus planning (180-day rule): If you accrue a bonus at year-end, it generally needs to be paid within 180 days after year-end for the corporation to keep the deduction for that year under subsection 78(4).

Financing, covenants, and stakeholder reporting: Lenders and investors may care about timing and consistency. Pick a year-end that supports timely reporting before key renewal or reporting dates.

Accounting efficiency and turnaround times: December 31 year-ends are extremely common and can create capacity bottlenecks. A non-December year-end can mean smoother timelines.

Inventory and cutoff accuracy: If you carry inventory, pick a year-end when counting and cutoff can be done accurately. Poor cutoff creates messy financials and tax issues.

Group alignment (Holdco/Opco or multiple corporations): If you operate multiple companies, aligning year-ends can reduce admin and simplify reporting.

Program claims (e.g., SR&ED): If you claim programs that rely on fiscal-year tracking, pick a year-end that matches your project cycle and documentation readiness.

3) Common year-end choices

There is no single best year-end. These are common patterns:

• December 31: Simple to think about and aligns with the calendar year, but often collides with busy operations and industry-wide accountant capacity.
• March 31: Often works well for service businesses; gives a post-holiday runway, but overlaps with personal tax season.
• June 30: Useful for some seasonal businesses; watch for vacation delays in record collection.
• September 30: Can fit certain project cycles; avoid stacking it with year-end business planning and operational ramp-ups.

4) A simple process to pick your year-end

1. Map your business cycle (busy months, slow months, big collections, inventory timing).

2. Pick a year-end shortly after your busiest period ends (when records are cleanest).

3. Stress-test cash flow for the 2-3 month tax payment window.

4. Decide whether you’ll use owner bonuses and ensure you can pay within 180 days if you want the deduction in the year accrued.

5. Confirm any lender/investor reporting expectations.

6. Lock it in by filing your first T2 for that fiscal period.

FAQ

Can I choose any year-end date?

Filing is generally due within 6 months after year-end. Payment of the balance is generally due 2 months after year-end (or 3 months for some eligible CCPCs).

Can I change my year-end later?

Often yes, but CRA generally expects you to request approval and provide reasons and the effective date.

Need help choosing the right year-end?

If you tell us your industry, busiest months, whether you carry inventory, and how you pay yourself (salary vs dividends vs bonus), we can recommend a year-end that fits your cash flow and tax planning goals.
