Corporate tax filing in Canada is based on your corporation’s fiscal year, not the calendar year. The T2 return is generally due six months after your fiscal year-end. The tax you owe, however, is usually due sooner: two months after year-end, or three months for certain Canadian-controlled private corporations (CCPCs) that meet the conditions.
Two deadlines, not one
It helps to keep the filing deadline and the payment deadline separate. Filing late can lead to penalties, while paying late can lead to interest, even if the return itself is filed on time.
- T2 filing: due six months after the end of the fiscal year.
- Tax owed: generally due two months after year-end.
- Certain CCPCs: may have three months to pay, where the conditions are met.
If your year-end is December 31, for example, the T2 is generally due June 30 and the balance is generally due by the end of February. If your fiscal year-end falls on a different date, count forward from that date instead.
What goes into a T2 return?
A T2 reports the corporation’s income, deductions, and taxes for the year. It is usually supported by financial statements, which show how income was calculated. Common supporting records include general ledgers, payroll records, and loan or shareholder-loan records, where they apply.
Clean books make a T2 much easier to prepare. When revenue, expenses, payroll records, and loan or shareholder-loan balances are organized, there is less guesswork and less back-and-forth at year-end. If your books need work before filing, Accounting & Bookkeeping services can help bring them up to date.
The small-business rate, in plain terms
For a CCPC, the small-business rate is approximately 9% to 13% on the first $500,000 of active business income, depending on the province. Above that amount, or for other types of income, the combined rate varies because the federal and provincial rates work differently.
That range is a general guide, not a quote for your corporation. Eligibility, the type of income, and the province all matter, so it is worth confirming the rate that applies to your situation before you rely on it for planning.
Why year-end planning matters
Many corporate tax decisions are easier before the year ends than after it. Reviewing income, expenses, and planned purchases ahead of year-end gives you time to ask questions and gather documents, rather than rushing to reconstruct them for the T2.
CRA correspondence: what to expect
After filing, the CRA may send a notice of assessment, ask for supporting documents, or propose changes. That is a normal part of the process, not automatically a sign of a problem.
Do not ignore CRA correspondence. If you are unsure what a letter means, ask for help before the deadline in the letter passes.
Common mistakes to avoid
- Confusing the six-month filing deadline with the earlier payment deadline.
- Using a calendar-year deadline for a corporation with a different fiscal year-end.
- Leaving shareholder loans, personal expenses, or year-end adjustments undocumented.
- Filing from incomplete books and hoping to fix details later.
- Ignoring a CRA letter because it looks routine.
