Losing a loved one is never easy, and navigating their tax obligations during that time can feel overwhelming. As a legal representative or executor, one of your key responsibilities is filing a final T1 return on behalf of the deceased. Missing the deadline can result in penalties and interest, so understanding the rules upfront can save time, money, and stress.

When Is the Final Return Due?

The filing deadline depends on when the person passed away:

Death between January 1 and October 31: The final return and any balance owing are due by April 30 of the following year.

Death between November 1 and December 31: The deadline is 6 months after the date of death, on the same calendar day.

What If the Deceased (or Their Spouse) Was Self-Employed?

If the person who died or their spouse or common-law partner living with them was running a business at the time of death, different filing deadlines apply:

Death between January 1 and December 15: Filing deadline is June 15 of the following year.

Death between December 16 and December 31: Filing deadline is 6 months after the date of death.

Important: Even with a later filing deadline for self-employed individuals, any balance owing must still be paid by the standard payment due date (generally April 30) to avoid interest charges.

Optional T1 Returns

In some cases, you may be able to file optional returns to reduce the overall tax burden of the estate. Each has its own deadline:

• Return for Rights or Things: Must be filed by the later of one year after the date of death, or 90 days after the Notice of Assessment for the final return is issued.

• Return for a Partner or Proprietor: Follows the same deadlines as the final return.

• Return for Income from a Graduated Rate Estate: Also follows the same deadlines as the final return.

T3 Trust Return (Estate Return)

If the deceased’s estate becomes a trust (such as a Graduated Rate Estate), a T3 Return must also be filed. The due date is 90 days after the trust’s tax year-end, which can be set to any date up to one year after the date of death.

Penalties for Late Filing

Filing late when there’s a balance owing triggers a CRA late-filing penalty of 5% of the amount owing, plus 1% for each additional full month the return is late (up to 12 months). The penalty can be even higher if the deceased had a late-filing penalty in any of the prior 3 tax years.

For T3 Returns filed late, an alternative penalty of $25 per day (minimum $100, maximum $2,500) may apply, even if there’s no balance owing.

The good news: Filing on time avoids the penalty even if you can’t pay in full.

Weekends & Public Holidays

If a due date falls on a Saturday, Sunday, or CRA-recognized public holiday, the return is considered on time if received or postmarked by the next business day.

Can Penalties Be Waived? In certain circumstances, the CRA may cancel or waive penalties and interest if the return was filed late due to circumstances beyond your control. You can submit a formal request to the CRA for relief.
