How T2 Filing Deadlines Work in Canada
| Deadline | Rule | Example (December 31 Year-End) |
|---|---|---|
| T2 filing deadline | 6 months after the end of the fiscal year. | December 31 year-end: T2 due June 30. |
| Tax payment deadline (CCPC, income under $500K) | 3 months after the fiscal year-end. Applies to CCPCs that claimed the Small Business Deduction and had taxable income under $500,000 in the prior year. | December 31 year-end: payment due March 31. |
| Tax payment deadline (all others) | 2 months after the fiscal year-end. Applies to non-CCPCs and CCPCs with taxable income of $500,000 or more in the prior year. | December 31 year-end: payment due March 1 (or February 28/29). |
| T4 filing deadline | Last day of February following the calendar year in which the remuneration was paid. Applies to all employers regardless of fiscal year-end. | All employers: T4s due February 28 (or next business day if weekend). |
| Quarterly instalment dates | Last day of each quarter of the fiscal year. Applies if estimated tax owing for the current year exceeds $3,000 (federal) or the corporation owed more than $3,000 in either of the two preceding years. | December 31 year-end: March 31, June 30, September 30, December 31. |
| Nil return deadline | Same as T2 filing deadline (6 months after year-end). CRA requires a T2 for every active corporation, even with no income or activity. | December 31 year-end: nil return due June 30. |
Filing Deadline vs. Payment Deadline: The T2 filing deadline (6 months) and the tax payment deadline (2 or 3 months) are different dates. You have 6 months to file the return, but the tax must be paid 2 or 3 months after year-end. If you file on time but pay late, you owe interest but no late filing penalty. If you file late, you owe the 5% + 1%/month penalty on top of the interest. Always file on time, even if you cannot pay in full. Corporate Tax Return Filing →

Late Filing Penalty and Interest Rules
| Situation | Penalty | Example: $30,000 Balance Owing |
|---|---|---|
| First-time late filing | 5% of the balance owing plus 1% per complete month late, up to 12 months. Maximum penalty: 17% of the balance. | Filed 6 months late: 5% + 6% = 11%. Penalty: $3,300. |
| Repeat late filing (filed late in any of the last 3 years) | 10% of the balance owing plus 2% per complete month late, up to 20 months. Maximum penalty: 50% of the balance. | Filed 6 months late (repeat): 10% + 12% = 22%. Penalty: $6,600. |
| Filed on time, paid late | No late filing penalty. Interest only. CRA's prescribed rate (approximately 9% to 10% compounding daily) on the unpaid balance from the payment deadline. | Paid 6 months late: approximately $1,500 in interest (no penalty). |
| Filed late with $0 balance owing | No penalty. The penalty is calculated on the balance owing. If you owe $0, the penalty is $0 regardless of how late you file. However, CRA may restrict corporate status for repeated non-filing. | No balance: $0 penalty even if filed 12 months late. |
Repeat Late Filing Doubles the Penalty: If CRA assessed a late filing penalty on any of your last 3 tax returns and you file late again, the penalty doubles: 10% base (instead of 5%) plus 2% per month (instead of 1%). On a $50,000 balance filed 6 months late, the first-time penalty is $5,500 (11%). The repeat penalty is $11,000 (22%). File on time every year. The penalty for late filing is always more expensive than paying a CPA to file it for you.

Weekend and Holiday Adjustment Rules
| Rule | Details |
|---|---|
| Deadline falls on a Saturday | The deadline moves to the next Monday. CRA considers the filing or payment on time if received by end of day Monday. |
| Deadline falls on a Sunday | The deadline moves to the next Monday. |
| Deadline falls on a federal statutory holiday | The deadline moves to the next business day. Federal holidays include: New Year's Day, Good Friday, Victoria Day, Canada Day, Labour Day, National Day for Truth and Reconciliation, Thanksgiving, Remembrance Day, Christmas Day, Boxing Day. |
| Interest accrual | Interest begins on the original due date, not the adjusted date. If the payment deadline is February 28 (Saturday) and you pay on Monday March 2, the payment is "on time" for penalty purposes but interest accrues from February 28. |
Frequently Asked Questions: T2 Filing Deadlines
When is my T2 filing deadline?
6 months after the end of your corporation's fiscal year. December 31 year-end: June 30. March 31 year-end: September 30. July 31 year-end: January 31. Use the calculator above to get your exact deadline adjusted for weekends and holidays.
When is the tax payment deadline?
2 months after your fiscal year-end for most corporations. 3 months for CCPCs that claimed the Small Business Deduction and had taxable income under $500,000 in the prior year. The payment deadline is earlier than the filing deadline. You must pay the tax before you file the return.
What happens if I file my T2 late?
Late filing penalty: 5% of the balance owing plus 1% per complete month late, up to 12 months (maximum 17%). If you filed late in any of the last 3 years, the penalty doubles: 10% plus 2% per month (maximum 50%). Interest is also charged from the payment deadline at approximately 9% to 10% compounding daily.
Is there a penalty if I owe $0?
No. The late filing penalty is calculated on the balance owing. If your balance is $0, the penalty is $0 regardless of how late you file. However, CRA requires a T2 for every active corporation and may restrict your corporate status or business number privileges for repeated non-filing.
Should I file on time even if I cannot pay?
Yes. Always file on time. If you file on time but pay late, you owe only interest (no penalty). If you file late, you owe both the penalty and the interest. Filing on time and setting up a payment arrangement with CRA always costs less than filing late. Corporate Tax Filing →
What is the difference between the filing deadline and the payment deadline?
The T2 filing deadline is 6 months after your fiscal year-end. The payment deadline is 2 months (or 3 months for qualifying CCPCs). You must pay the tax before the return is due. Many business owners confuse the two and assume they have 6 months to pay. They do not. Interest accrues from the payment deadline, not the filing deadline.
When are quarterly instalments due?
The last day of each quarter of your fiscal year. For a December 31 year-end: March 31, June 30, September 30 and December 31. Instalments are required if your estimated tax owing exceeds $3,000 for the current year, or you owed more than $3,000 in either of the two preceding years. CRA charges interest on late or insufficient instalments.
When are T4 slips due?
February 28 of the year following the calendar year in which the remuneration was paid (or the next business day if February 28 falls on a weekend). T4s are due by calendar year, not fiscal year. If your fiscal year-end is June 30, 2026, the T4 for salaries paid in 2026 is due February 28, 2027.
Do I need to file a T2 if my corporation had no activity?
Yes. CRA requires a T2 for every active corporation, including nil returns for corporations with no revenue, no expenses and no activity. The filing deadline is the same: 6 months after the fiscal year-end. Filing the nil return confirms the corporation is active and prevents CRA from restricting your business number.
Can a CPA file my T2 for me?
Yes. A CPA prepares the financial statements, T2 return, GIFI and all CRA schedules, then e-files electronically with CRA. At Gondaliya CPA, corporate tax filing starts from $400 and includes CRA audit support FREE. T2 filed FREE for every bookkeeping client. Book Free Consultation →
