Key takeaways
  • If the person died between November 1 and December 31, the final return is due 6 months after the date of death, on the same calendar day.
  • The later filing date does not move the payment date, so a balance may need to be paid before you file.
  • Self-employed people have their own rules, and weekend or holiday due dates roll to the next business day.

If the person died between November 1 and December 31, the final return is due 6 months after the date of death, on the same calendar day. For a death between January 1 and October 31, the final return is instead due April 30 of the year following the death.

This article explains how the six-month rule works, why the payment date can still arrive first, and which exceptions apply. If you are unsure which date governs, a lawyer or accountant can confirm it against the facts.

This article covers Canadian federal tax law, which applies in every province.

How the six-month rule works

If the person died between November 1 and December 31, the final return is due 6 months after the date of death, on the same calendar day. The Income Tax Act reflects this: where an individual dies after October and on or before the normal filing due date, the legal representative must file by the later of the normal due date and the day that is 6 months after the day of death.

In practice, you count forward six months from the date of death and land on the same day of the month. Once you have that date, check whether it falls on a weekend or holiday, and whether any of the exceptions below apply to your situation.

When is any balance due?

This is where people get caught. The payment date for a balance owing does not move with the later filing date. The CRA says the payment due date does not change, and you may need to pay before filing to avoid interest. Overpayments are generally refunded once the return is assessed.

Because the exact payment date can depend on the situation, confirm it before relying on the filing date. Estimating the tax early and paying what you can reduces interest, since interest compounds daily on unpaid amounts from the day after the due date.

Exceptions to check

Late filing consequences

A late final return with a balance owing carries a penalty of 5% of the balance plus 1% of the balance for each full month late, up to 12 months. It may be higher if a late-filing penalty was assessed on the deceased's return in any of the 3 previous years. Filing on time avoids the penalty even if the balance cannot be paid in full.

Interest also applies to late-filing penalties. The CRA may cancel penalties or interest where a late filing was caused by circumstances beyond your control.

What to do next

You do not need to wait for a court process to file the final return. The CRA accepts a will naming an executor or letters of administration, and Form RC552 is available where no executor exists or an appointment is pending.

Frequently asked questions

My parent died on December 3. When is the final return due?

A death between November 1 and December 31 means the final return is due 6 months after the date of death, on the same calendar day. If a business was operating, the date may differ.

Is the tax payment also delayed six months?

Not necessarily. The CRA says the payment due date does not change when the filing date is later, and you may need to pay before filing to avoid interest. Confirm the payment date for your situation.

What if the due date is a Saturday?

A return is on time if received or postmarked by the next business day. A payment is on time if received the first business day after the due date.

Do I need a second return for the prior year?

If the T1 for a year before the year of death was not filed, the legal representative must make sure it is filed. A separate rule applies where death occurs early in the year before the prior-year deadline.
