Key takeaways

• A fiscal year in Canada is any 12-month accounting period your business uses to report income and expenses to the Canada Revenue Agency (CRA). It doesn't have to match the calendar year.
• Canadian corporations can choose any date as their fiscal year-end, giving you flexibility to align your finances with your business cycle.
• Sole proprietors and individuals use December 31 as their fiscal year-end, unless they apply to the CRA for an alternative fiscal period.
• Picking the right fiscal year-end affects your tax planning, filing deadlines, and how smoothly your year-end bookkeeping runs.

What is a fiscal year in Canada?

A fiscal year (also called a fiscal period) is the 12-month window your business uses to report income and expenses. At the end of this period, you file your tax return with the CRA.

Your fiscal year doesn't have to start on January 1. While individuals and sole proprietors generally follow the calendar year, corporations have more flexibility. The key rule is that your fiscal period can't exceed one year.

The Canadian federal government runs on a fiscal year from April 1 to March 31. Individual taxpayers, on the other hand, always report income from January 1 to December 31.

Fiscal year vs calendar year

A calendar year always runs from January 1 to December 31. A fiscal year can start and end in any month, as long as it covers 12 months.

Here's how they compare in the Canadian context:

• Calendar year (January 1 to December 31): required for individual taxpayers, sole proprietors, and most all-individual partnerships.
• Fiscal year (any 12-month period): available to corporations, which can select any month-end that suits their operations.
• Government fiscal year (April 1 to March 31): used by federal and most provincial governments in Canada.

If you're running a corporation, you get to pick. If you're a sole proprietor, December 31 is your default, though, you can apply to change it.

Fiscal year rules by business type

Your business structure determines how much choice you have over your fiscal year-end.

Corporations

Canadian corporations have the most flexibility when choosing a fiscal year-end. You can pick any dated that works for your business.

Your first fiscal year starts on the date of incorporation. It can run for up to 53 weeks (371 days), which means you can stretch that initial period to cover a little more than one calendar year. After your first year, each fiscal period must be 12 months.

You declare your fiscal year-end when you file your first T2 corporate income tax return with the CRA. Once you've set it, you use the same year-end each year unless you apply to change it.

Sole proprietors

If you're a sole proprietor, December 31 is your fiscal year-end. The CRA treats your business income as personal income, so your fiscal period matches the calendar year.

There is one alternative. You can apply to the CRA using Form T1139 (Reconciliation of Business Income for Tax Purposes) to use a non-calendar fiscal period. This option involves complex calculations each year and requires you to include an estimate of income earned between your chosen year-end and December 31.

For most sole proprietors, sticking with December 31 is the simpler route.

Partnerships

Partnerships where all partners are individuals also use a December 31 fiscal year-end. The same calendar-year rule that applies to sole proprietors applies here, as does the option to apply to change the year-end date using Form T1139.

If a corporation is one of the partners, the partnership can choose its own fiscal year-end.

Professional corporations in partnerships (such as law or accounting firms) must use December 31.

How to choose a fiscal year-end for your business

If you're incorporating a new business, choosing your fiscal year-end is one of the first financial decisions you'll make. Here are the factors to consider.

Align with your business cycle

Pick a fiscal year-end that falls after your busiest period. This gives you a clearer picture of your annual performance and makes it easier to plan for the year ahead.

For example, if you run a retail business with peak sales in November and December, a January 31 fiscal year-end captures your full holiday season in one reporting period. A landscaping business with peak revenue in summer months might choose a September 30 or October 31 year-end.

Ending your fiscal year during a slow period also makes stocktaking and account reconciliation less disruptive to daily operations.

Consider tax planning opportunities

Your fiscal year-end date affects when you can use certain tax strategies.

When choosing your first fiscal year-end, consider which months will fall into that initial period. If your highest-earning months fall late in the year, ending your first fiscal year before them keeps that first year's income lower – which can help you stay within the small business deduction limit of $500,000 of active business income.

Talk to an accountant before making decisions based solely on tax planning. The right strategy depends on your full financial picture.

Think about accountant availability and costs

December 31 is the most common fiscal year-end in Canada. That means accountants are busiest from January through April. If your fiscal year ends in December, you're competing with millions of other businesses and individual taxpayers for your accountant's time.

Choosing an off-cycle year-end (such as June 30 or September 30) can work in your favour:

• Your accountant has more time to review your files carefully.
• You may pay lower fees during off-peak months – though this won’t always apply.

Align with funding or government cycles

If your business receives government grants or contracts, a March 31 fiscal year-end may simplify your reporting. Canadian federal and provincial governments end their fiscal year on March 31, so aligning with this cycle makes it easier to match grant periods with your own financial statements.

Businesses that report to investors or parent companies may also benefit from matching fiscal year-ends for smoother consolidation.

Tax filing deadlines based on fiscal year-end

Your fiscal year-end determines your tax filing and payment deadlines. Here's what to keep in mind.

For corporations:

• File your T2 corporate income tax return within six months of your fiscal year-end.
• Pay any balance owing within two months of your fiscal year-end.
• If you qualify as a Canadian-controlled private corporation (CCPC) and claim the small business deduction in the current or prior year, and your taxable income in the prior year did not exceed the small business limit, you get three months to pay.

For sole proprietors:

• File your T1 personal income tax return by 15 June of the following year.
• Pay any taxes owing by 30 April of the following year.

Even though the filing deadline is 15 June, interest on any balance owing starts on 1 May. Filing early helps you avoid unnecessary interest charges.

How to change your fiscal year-end

There are several reasons you might want to change your fiscal year-end. Perhaps your business cycle has shifted, you've restructured, or you want to align with a parent company.

To change your corporate fiscal year-end, follow these steps:

1. Write to the CRA before your current fiscal year-end to request the change – you can’t change the year-end date for a period that’s already started.
2. Explain why you want to change and what new year-end you'd like.
3. Wait for written approval from the CRA before filing based on the new period.
4. File a short-period return covering the gap between your old year-end and new one.

If the CRA approves the change, you'll have a short fiscal year (less than 12 months) in the transition period. Your tax filing and payment deadlines adjust based on the new year-end.

Changing your fiscal year-end may also affect your Goods and Services Tax/Harmonized Sales Tax (GST/HST) reporting period. Check with the CRA or your accountant to understand how the change flows through to your GST/HST filings.

Sole proprietors who use the alternative fiscal period method (Form T1139) can return to a December 31 year-end at any time. However, this change is permanent – you can’t switch back again later.

FAQs on fiscal years in Canada

Here are answers to common questions about fiscal years in Canada.

Can I choose my own fiscal year-end?

Yes. Corporations can choose any date as their year-end. Sole proprietors and all-individual partnerships use December 31 as default, but can apply to the CRA for an alternative fiscal period using Form T1139.

What fiscal year-end should I choose for my corporation?

Choose a year-end that falls after your peak business season, when you’re operationally quieter and accountant has more availability. Also consider the 53-week rule for your first year and any tax planning strategies that depend on timing.

Do sole proprietors have to use December 31?

December 31 is the default year-end for sole proprietors. You can apply for a non-calendar fiscal period through the CRA, but the additional reporting requirements make this option complex for most small businesses.

How do I change my fiscal year-end with the CRA?

Write to the CRA before your current year-end to request the change you want applied in the next fiscal period and the reason. If approved, you file a short-period return covering the transition.

What are the tax filing deadlines based on fiscal year-end?

Corporations must file their T2 return within six months of their fiscal year-end and pay taxes within two months (three months for CCPCs that meet the small business deduction conditions). Sole proprietors file by 15 June with taxes due 30 April.
