Personal Tax Return Deadlines (T1):

Regular individuals: Due by April 30th.
For those self-employed or if their spouse/common-law partner runs a business: Due by June 15th.

Deadlines for Deceased Persons:

If the death took place between January 1st and October 31st: The final return is due by April 30th of the subsequent year.
If the death was between November 1st and December 31st: The final return is due 6 months post the date of death.

Death between January 1st and December 15th: Final return due by June 15th of the next year.
Death from December 16th to December 31st: Final return due 6 months after the death date.

Payment Deadlines:

Generally, 2 months post the year-end.
For specific Canadian-controlled private corporations (CCPCs): 3 months post the year-end.

Note: If a deadline lands on a weekend or a CRA-recognized public holiday, submissions are considered timely if received or postmarked the subsequent business day. Payments are also deemed timely under these conditions.

Interest on Outstanding Taxes:

If you owe taxes for the current year and don’t clear the balance by April 30th, the CRA begins charging compound daily interest starting May 1st. This applies even if your return undergoes reassessment. The interest rate, which can vary every quarter, is determined by prescribed rates.

Potential Penalties:

Late Filing:
First-time offense: 5% of unpaid tax + 1% of unpaid tax for each outstanding month (up to 12 months).
Subsequent offenses: 10% of unpaid tax + 2% of unpaid tax for each outstanding month (up to 20 months).

Repeated Underreporting of Income (≥ $500, more than once in 3 years): Lesser of 10% of unreported income or 50% of the tax discrepancy.

False Statements or Omissions: Greater of $100 or 50% of the understated tax. (Penalties might be waived if inaccuracies are voluntarily reported to CRA).
