Tax Season Deadlines

For the 2025 tax year, the following deadlines apply:

  • March 2, 2026: RRSP Contribution Deadline. This is the final day to contribute to a Registered Retirement Savings Plan (RRSP) to reduce your taxable income for the 2025 tax year.
  • April 30, 2026: General Filing & Payment Deadline. This is the deadline for most individuals to file their 2025 tax return and pay any balance owing to avoid interest.
  • June 15, 2026: Self-Employed Filing Deadline. If you or your spouse/common-law partner is self-employed, you have until this date to file your return. Note: Any taxes owed must still be paid by April 30, 2026, to avoid interest.
