Key Tax Deadlines for Self-Employed (2025 Tax Year)
Tax Payment Due Date: April 30, 2026
Tax Return Filing Deadline: June 15, 2026
GST/HST Return Deadline: Generally June 15, 2026 (though payment is due April 30)
Important Considerations
If You Owe Money: While you have until June 15 to file, interest begins accruing on any unpaid taxes after April 30.
Weekend Rule: As June 15, 2026, is a Monday, the deadline is not extended for the weekend.
Instalments: If the CRA requires you to pay in instalments, these are typically due on March 15, June 15, September 15, and December 15.
Penalty: Late filing results in penalties and interest. If you cannot afford to pay, you should still file on time to avoid the late-filing penalty
