A corporation’s fiscal year-end is the date on which its annual accounting period closes. It determines when the T2 corporate return is due, when corporate tax is payable, when the year-end planning review needs to happen, and how salary, bonus, and dividend decisions interact with the shareholder’s personal tax year. For an incorporated IT contractor, understanding how the fiscal year-end was set and what it means for ongoing planning is a foundational part of running the corporation correctly.
Unlike a sole proprietor, whose business income is generally reported on a calendar-year basis, a corporation can usually choose a non-calendar fiscal year-end. That choice is declared on the corporation’s first T2 return after incorporation, subject to the 53-week maximum for the first tax year and special rules for certain professional corporations that are members of partnerships. The year-end can be changed later, but generally only with CRA approval.
How the Fiscal Year-End Is Set
When a corporation is incorporated federally or provincially, the first fiscal year-end is typically established at the time of the first T2 filing. CRA’s corporation tax-year guidance says the corporation’s first tax year starts on the date of incorporation and cannot be longer than 53 weeks. The corporation chooses a year-end date within that limit, and from that point forward the fiscal year runs on the same annual cycle until a change is made.
A corporation that is incorporated on March 15, 2024, and chooses a January 31 fiscal year-end will have a first short fiscal year running from March 15, 2024, to January 31, 2025. Subsequent years will run February 1 to January 31. A first year shorter than twelve months is normal, though some limits, thresholds, or instalment mechanics may be prorated or calculated differently for a short year.
The fiscal year-end does not need to align with the calendar year. It does not need to align with the GST/HST fiscal year, though most businesses keep those aligned for simplicity. It is simply the date chosen when the corporation established its first annual filing cycle.
December 31 vs Non-Calendar Year-Ends
Many incorporated contractors use December 31 as their fiscal year-end. The appeal is administrative simplicity: the corporate year aligns with the personal tax year, and financial statements, payroll records, and bank reconciliations all close at the same time. For a contractor running a lean operation with no employees other than themselves, December 31 reduces the number of different year-end dates to track.
The trade-off is timing. With a December 31 fiscal year-end, the T2 filing deadline is June 30 of the following year. The corporate tax balance is generally due February 28, approximately two months after year-end, but an eligible CCPC that claimed the small business deduction may have a March 31 balance-due date. The GST/HST annual return, if the corporation files annually and its GST/HST fiscal year is also December 31, is due March 31. Salary or bonus planning for the corporate year should be reviewed before December 31, while dividends are personal income based on the date they are declared. Everything converges around the same season.
A non-calendar fiscal year-end separates the corporate cycle from the personal one. A January 31 fiscal year-end, for example, means the corporate year closes one month after the personal year. A March 31 fiscal year-end means the corporate year closes three months after the personal year. This separation has practical implications for planning, corporate tax cash flow, and the timing of salary or bonus accruals, but it does not by itself determine the calendar year in which a dividend is taxed personally.
What Timing Really Changes
There are two timing systems operating at once. The corporation reports its income on the T2 for its fiscal year. The shareholder reports salary, bonuses, and dividends on the T1 for the calendar year in which they are paid, credited, or declared, depending on the type of compensation.
For a non-professional CCPC with a January 31 fiscal year-end, income earned by the corporation in the fiscal year ending January 31, 2025, is reported on the T2 for that fiscal year. A dividend declared in February 2025 is personal income on the shareholder’s 2025 T1. That result comes from the dividend declaration date, not from the January 31 year-end itself. A December 31 corporation can also declare a dividend in February 2025 from retained earnings, provided corporate law and accounting requirements are satisfied.
Salary and bonus planning is where the fiscal year-end has more direct practical force. Salary or a bonus accrued before the corporate year-end may be deductible in that corporate year, but subsection 78(4) of the Income Tax Act can deny the deduction until a later year if the remuneration is still unpaid 180 days after the year-end. A non-calendar year-end therefore changes the planning window for salary accruals and payment timing.
The timing benefit is real but modest. For a contractor in a stable income situation with a predictable annual pattern, the benefit is often more about cash-flow management and administrative workflow than large personal tax savings. For a contractor in a year with unusually high income, a non-calendar year-end may provide more time to estimate corporate income and coordinate salary, bonus, and dividend decisions. The decision to use a non-December fiscal year-end primarily for timing purposes should be evaluated against the added complexity it introduces.
Impact on Tax Filing Deadlines
The fiscal year-end determines when key corporate deadlines fall.
T2 filing deadline. The T2 corporate return is due six months after the fiscal year-end. A December 31 year-end produces a June 30 filing deadline. A March 31 year-end produces a September 30 deadline. A January 31 year-end produces a July 31 deadline.
Corporate tax payment deadline. The general corporate balance-due day is two months after the fiscal year-end. A CCPC may qualify for a three-month balance-due day for regular corporate income tax if it was a CCPC throughout the year, claimed the small business deduction for the current or previous year, and meets the taxable-income/business-limit criteria. Corporate instalments are generally monthly, but eligible CCPCs with a perfect compliance history and income and taxable-capital amounts under CRA’s thresholds may pay quarterly instalments instead.
GST/HST annual return. For most annual-filing corporations, the GST/HST return and final payment are due three months after the GST/HST fiscal year-end. This is often the same date as the corporate income-tax fiscal year-end, but it does not have to be. The GST/HST filing guide covers the filing and instalment structure for annual filers.
The clustering or separation of these deadlines is one practical reason contractors choose a particular fiscal year-end. A contractor who wants corporate tax and GST/HST due dates concentrated in the first quarter may prefer a December 31 year-end. A contractor who wants to spread administrative work more evenly may prefer a different date.
Impact on Year-End Compensation Planning
The fiscal year-end also determines when the year-end planning review needs to happen. For a December 31 year-end corporation, the compensation decision, shareholder loan review, and RRSP planning all converge in November and December, which coincides with year-end for the personal tax return. For a March 31 year-end corporation, the corporate year-end planning happens in January and February, which is separate from the December personal planning but coincides with RRSP season.
RRSP contribution room is based on earned income for the calendar year, not the corporate fiscal year. A contractor with a March 31 fiscal year-end needs to ensure that salary is paid or credited before December 31 if the intent is to generate RRSP room from that calendar year’s employment income. Salary paid after December 31 from a fiscal year that started before December 31 generates room based on the year in which the salary is paid or credited, not the year the corporate fiscal year started.
The year-end review guide covers the compensation and planning decisions that need to be made before the fiscal year closes.
Changing the Fiscal Year-End
A corporation can change its fiscal year-end. The process generally involves writing to CRA to ask for approval, explaining the reason for the change and the effective date. If the change is accepted, the corporation files a T2 for the short fiscal year that results from the transition, and the change affects the timing of all subsequent filings and payments.
CRA’s change of fiscal year-end guidance lists the situations where approval is not required, including certain final returns, emigration or exempt-status changes, acquisitions of control, and changes in CCPC status. A corporation that changes from a December 31 year-end to March 31 will usually have a short fiscal year from January 1 to March 31 in the transition year.
The reasons a contractor might change the fiscal year-end include: simplifying the filing cycle, separating corporate and personal planning timelines, or aligning the corporate year with the natural business cycle of the contracting work. A change made without a clear reason for it creates a transition-year short return, a recalculated instalment cycle, and potential confusion in the compensation planning timeline. The decision is worth reviewing with a CPA before filing the change.
GST/HST Alignment
The corporation’s GST/HST fiscal year does not automatically match the income tax fiscal year. CRA uses the term fiscal year to refer to both, but they operate under different statutory provisions. For most small businesses, the GST/HST fiscal year is often set to align with the income tax fiscal year, and most contractors keep them aligned to simplify reporting.
If the fiscal year-end changes for income tax purposes, the GST/HST fiscal year should be reviewed to confirm whether it needs to be updated separately. Filing GST/HST returns based on a different fiscal year than the T2 can create reconciliation complications because revenue, ITCs, instalments, and income-tax reporting no longer close on the same date. The GST/HST filing guide covers the filing cycle mechanics.
Quebec Perspective
For Quebec-resident incorporated contractors, the fiscal year-end affects both the federal T2 and CO-17 returns. Both use the same fiscal year, and federal and Quebec filing and payment deadlines are calculated by reference to that year-end. Revenu Québec administers the CO-17 separately from CRA’s T2 administration; a change to the fiscal year-end needs to be reflected in both filing systems.
Quebec’s CCPC tax rate structure and the small business deduction under the Quebec Act are applied to the same fiscal year as the federal return. There is no separate Quebec fiscal year for the corporation.
The fiscal year-end is one of the foundational parameters of a corporation’s compliance calendar. It shapes when decisions need to be made, when returns are due, and how corporate compensation planning interacts with the shareholder’s personal tax position. Many contractors choose the year-end during the first T2 cycle without much deliberation, which is fine for a December 31 year-end that simplifies everything into one cycle. For a contractor who wants to use the fiscal year structure more intentionally, understanding what the date controls is the starting point.
