With the new year behind us, it is crucial to be cognizant of the upcoming tax deadlines in early 2026. In this article, we will discuss a few important deadlines that you should be aware of.
Deadlines: End of February / Throughout March
RRSP
The deadline for contributing to an RRSP for the 2025 tax year is March 2nd, 2026.
The annual RRSP deduction limit is calculated as 18% of your prior year’s earned income (i.e., employment income), up to a predetermined maximum per year. For 2025, the predetermined maximum was $32,490 (18% of $180,500 of earned income). Any undeducted RRSP contributions and unused RRSP deduction room can be carried forward to subsequent years. Both your contribution limit and any carry-forward contribution room should be available on your annual notice of assessment from the CRA if you filed your taxes in the previous year. Be mindful that over contribution to a RRSP may result in unwanted penalties and interest.
T4 and T5 Slips
T4 Summary and Slips should be filed for salaries paid to individuals during 2025. Similarly, T5 Summary and Slips should be filed for dividends paid during the year.
The deadline to file 2025 T4 and T5 Summary and Slips is February 28th, 2026*.
Final payments of corporate income taxes
Final payments of corporate income taxes are required within two months of each taxation year-end (Note: eligible Canadian-controlled private corporations may qualify for a three month final payment due date). For a corporation that does not qualify for the three-month due date and that has a December 31, 2025 year-end, the final payment due date is February 28th, 2026*.
Trust returns
T3 Trust income tax and information return should be filed 90 days after the trust’s tax year-end. For a Trust that has a December 31, 2025 year-end, the deadline to file is March 31st, 2026.

Deadlines: End of April / June
Final payments of personal income taxes
Final payments for personal income taxes are required to be paid by April 30th, 2026. This payment deadline also applies to individuals with self-employment income, who have a personal tax filing deadline of June 15th, 2026.
Vacant Home Tax ("VHT") Declaration
The Toronto VHT is a tax on residential properties in Toronto that are considered vacant. To avoid assessment of VHT, Toronto homeowners are required to declare occupancy status of their property every year.
VHT is calculated at 3% of the property’s current value assessment ("CVA") for the year in which the home is vacant.
The deadline to complete the VHT Declaration is April 30th, 2026.

* When a due date falls on a Saturday, Sunday or public holiday recognized by the Canada Revenue Agency (CRA), the return is considered filed and the payment is considered to be made on time if the CRA receives the filing—or the payment or filing is postmarked—on or before the next business day. In these instances, since the due date falls on a weekend or a federal holiday, the filing or payment deadline is the first working day that follows.
