When Is the T2 Corporate Tax Deadline? Filing vs Payment Dates Explained

There are two separate T2 deadlines every incorporated business owner in BC must track: the return filing deadline (6 months after your corporation's fiscal year-end) and the balance-of-tax payment deadline (generally 2 months after year-end, or 3 months for eligible Canadian-controlled private corporations claiming the small business deduction). Missing either one triggers penalties or interest — and many business owners confuse the two.

The two deadlines at a glance

Deadline — When it falls — What it covers
T2 return filing — 6 months after fiscal year-end — The completed T2 return must reach CRA by this date
Balance of tax owing (general) — 2 months after fiscal year-end — Any remaining corporate tax must be paid
Balance of tax owing (eligible CCPCs) — 3 months after fiscal year-end — Extended payment deadline for qualifying small businesses

The most important takeaway: you can owe money and face interest well before your return is even due. Many incorporated contractors in the Fraser Valley are surprised to learn that the payment clock runs ahead of the filing clock.

A concrete example

Suppose your corporation has a December 31 fiscal year-end — the most common choice for incorporated businesses.

Balance of tax owing (general rule): due February 28 of the following year (2 months after December 31).
Balance of tax owing (eligible CCPC with small business deduction): due March 31 of the following year (3 months after December 31).
T2 return filing deadline: due June 30 of the following year (6 months after December 31).

So for a December 31, 2024 year-end: the payment was due by late February or March 2025, but the return itself is not due until June 30, 2025. Filing late does not excuse a late payment.

What if my fiscal year-end is not December 31?

Canada's tax system allows corporations to choose any fiscal year-end (subject to CRA approval). The same rules apply proportionally. Example: a fiscal year-end of March 31 means a general payment deadline of May 31, a CCPC extended payment deadline of June 30, and a T2 filing deadline of September 30.

If a deadline falls on a weekend or statutory holiday, CRA generally accepts the next business day. Confirm the exact date for your filing year.

The CCPC three-month payment rule — who qualifies?

To use the extended 3-month payment deadline, your corporation generally must be a Canadian-controlled private corporation (CCPC) that claimed the small business deduction in either the current year or the preceding tax year, and certain conditions regarding associated corporations and taxable income must be met. This is a nuanced rule — if you are unsure whether your corporation qualifies, confirm with your CPA before assuming you have the extra month.

What about corporate tax instalments?

If your corporation expects to owe more than a threshold in corporate income tax (confirm for the current tax year), CRA requires monthly or quarterly instalment payments throughout the year. These are not the same as the year-end balance-of-tax payment. Many incorporated contractors in Abbotsford overlook instalments in their first few years of incorporation, leading to an unexpected interest charge at year-end.

Frequently asked questions

Can I file my T2 early?

Yes. CRA accepts T2 returns as soon as the fiscal year has ended. Filing early is generally advisable if you are expecting a refund. There is no penalty for early filing.

What if I cannot pay the full balance by the payment deadline?

You should still file on time and pay as much as possible. CRA charges prescribed interest on any unpaid balance from the day after the payment deadline (confirm the current rate at canada.ca). Partial payment reduces the interest base; it does not eliminate it.

I have multiple corporations — do they each have their own T2 deadline?

Yes. Each corporation files its own T2 based on its own fiscal year-end. A tax calendar maintained by your CPA is essential to avoid missed deadlines.
