Late Filing Your Corporate Return: Never a Good Idea
UPDATE (June 11, 2026): This article has been updated to reflect changes in legislation, regulations, and accounting practices since the original date of publication (April 15, 2019).
Corporations are generally required to file their income tax return within six months of the end of their taxation year. While many business owners focus on whether tax is owing, filing late can create issues even when the corporation has no balance due.
A late return can lead to penalties, delayed refunds, missed planning opportunities, and additional compliance issues. In other words, even if your corporation had a loss, overpaid its instalments, or does not expect to owe tax, it’s still important to file on time.
Late-filing penalties
If a corporation files its T2 return late, the Canada Revenue Agency (CRA) may charge a penalty based on unpaid tax owing at the filing deadline. The general penalty is 5% of the unpaid tax, plus 1% of the unpaid tax for each complete month the return is late, up to a maximum of 12 months.
If no tax is owing, the basic late-filing penalty may be nil. However, that does not mean late filing is harmless. Repeated late filing can increase the risk of larger penalties or additional CRA follow-up, particularly where CRA has already contacted the corporation about outstanding returns.
Refunds can be delayed or lost
Late filing can also affect your ability to receive a refund. In many cases, corporate refunds may be limited if the return is filed more than three years after the end of the taxation year.
A refund can arise even in a loss year. For example, your corporation may have made instalment payments during the year or have other refund-generating items. If the return is not filed within the required timeline, that refund may be delayed or lost.
Planning opportunities can be delayed
Filing late can also slow down or complicate tax planning. For example, if your corporation has losses, overpaid instalments, or other refund-generating items, your advisor may need the return filed before determining whether refunds or other planning opportunities are available.
Even when no tax is owing, filing on time helps keep those options open and allows your advisor to review the corporation’s position properly.
Non-resident corporations face additional risk
Non-resident corporations that carry on business in Canada may be required to file a Canadian corporate tax return, even if no Canadian tax is payable.
These corporations can face late-filing penalties even where the regular unpaid-tax-based penalty would otherwise be small or nil. If your corporation is non-resident or has cross-border activity, it’s especially important to confirm filing requirements early.
Information returns are easy to overlook
A corporation’s compliance obligations may extend beyond the T2 return. Depending on the circumstances, additional information returns may be required, including Form T106 for certain non-arm’s length transactions with non-residents, and Form T1134 for certain foreign affiliate reporting.
These forms have their own filing deadlines and can carry late-filing penalties. They are often easy to miss when year-end work is rushed or when a corporate return is filed late.
File early and avoid surprises
Filing your corporate return on time helps reduce the risk of penalties, preserve refund opportunities, and keep your corporation’s tax filings in good order.
