Complete guide to every CRA tax deadline in 2026.
π Key 2026 dates (for the 2025 tax year):
- March 2 β RRSP contribution deadline for the 2025 tax year (statutory March 1 fell on a Sunday)
- March 2 β T4, T4A and T5 information slips due (last day of February fell on a Saturday)
- March 16 β Q1 personal instalment (March 15 fell on a Sunday)
- April 30 β T1 personal tax filing and payment deadline
- June 15 β Self-employed filing deadline β payment was still due April 30
- June 15 β Q2 personal instalment
- June 30 β T2 corporate filing for a December 31 year-end (6 months after fiscal year-end)
- September 15 β Q3 personal instalment
- December 15 β Q4 personal instalment
- December 31 β Single farmer/fisher instalment
β³ Where the year stands (reviewed 1 September 2026): everything up to and including June 30 has already passed for the 2025 tax year. Still ahead in 2026: the September 15 and December 15 instalments, and the December 31 farmer/fisher instalment. If a 2025 return is still unfiled, filing now stops the late-filing penalty growing (it caps at 12 months), though interest keeps compounding daily on any balance owing.
β οΈ Do not quote these as upcoming without checking today's date against the list above. When a deadline falls on a weekend or a CRA-recognized public holiday, the CRA treats a return or payment as on time if it arrives the next business day.
