Canadian Corporate Tax Deadlines 2025: What You Need to Know
As a Canadian small business owner, missing a tax deadline can result in costly penalties and interest from the CRA. At Optax, we believe compliance should be automatic, but understanding the schedule is crucial for cash flow planning.
The T2 Filing Deadline
For most corporations, the T2 Corporation Income Tax Return is due six months after the end of your fiscal year.
- Example: If your year-end is December 31, 2024, your T2 return is due on June 30, 2025.
- Exception: If the filing deadline falls on a Saturday, Sunday, or public holiday, the CRA considers the return filed on time if postmarked on the next business day.
Tax Payment Deadline vs. Filing Deadline
Critically, the deadline to pay your taxes is earlier than the deadline to file.
- CCPCs (Canadian-Controlled Private Corporations): Any balance owing is generally due three months after your year-end. (e.g., March 31 for a Dec 31 year-end).
- Other Corporations: Balance is due two months after year-end.
Installment Payments
If your corporation owed more than $3,000 in taxes in either of the two preceding tax years, you are likely required to make monthly or quarterly installment payments. Be sure to check your "CRA My Business Account" for your specific schedule.
