Key takeaways
  • The tax and filing deadlines that run from the date of death or the date of the certificate are what usually matter in practice.
  • A named executor is not required to act, but once they do, the job includes taxes, bills, debts and distribution.
  • The final income tax return is generally due April 30 of the following year for deaths between January 1 and October 31.
  • An Estate Information Return is due within 180 calendar days after the certificate is issued.

Grief, family logistics and paperwork can easily push an application for a certificate down the list. If months have passed since the death, you may be worried that you have missed a deadline.

This article looks at the time pressures that are clearly set out for Ontario executors. Whether any specific time limit applies to applying for the certificate itself depends on the facts and is something a lawyer can confirm for you. What is clearer are the tax deadlines and practical consequences that keep running while you wait.

Start with the role itself

A named executor is not required to act. If you do take the role, Ontario's guidance describes it as winding up the deceased's affairs: paying taxes, bills and debts, collecting assets and distributing the rest. Early duties include filing the deceased's tax return and telling banks and financial institutions of the death.

If you are unsure whether you want the role, it is sensible to get advice before taking steps that look like acting as executor.

The deadlines that keep running

Even if a certificate has not yet been applied for, income tax deadlines are tied to the date of death. They do not pause while the estate waits.

ItemTiming
Final return, death January 1 to October 31April 30 of the next year
Final return, death November 1 to December 316 months after death
Final return if the deceased or spouse was self-employed (death January 1 to December 15)June 15 of the next year
Optional Rights or Things returnLater of one year after death or 90 days after the Notice of Assessment for the final return
Estate Information ReturnWithin 180 calendar days after the certificate is issued

Late filing of a final return with a balance owing carries a 5% penalty plus 1% per full month, up to 12 months, and compound daily interest. Because the penalty applies when there is a balance owing, delay can make a tax bill larger.

Practical costs of waiting

A graduated rate estate qualifies for no more than 36 months after death. Long delays can therefore affect tax planning options for the estate.

Value and tax if you apply late

Delay does not change how the Estate Administration Tax is measured. The estate value is the fair market value at the date of death of the assets the deceased owned. For certificates applied for on or after January 1, 2020, there is no tax on the first $50,000, and above that the rate is $15 per $1,000 or part of $1,000.

If the value must be estimated, the applicant swears the estimate, pays tax on it, and undertakes to file a sworn statement of total value within six months and pay any balance. If the estate cannot afford the tax at application, a judge can order payment later under s. 4(1) of the Estate Administration Tax Act, 1998.

What to do next

Frequently asked questions

Is there a set number of months to apply for probate in Ontario?

Whether a specific time limit applies to applying for the certificate depends on the facts and is worth confirming with a lawyer. What is clearly set out are the tax deadlines tied to the date of death and to the date the certificate is issued.

Will I be penalized for waiting to apply?

Late filing of the final tax return when a balance is owing carries a 5% penalty plus 1% per full month, up to 12 months, plus compound daily interest. The tax on the estate value is measured at the date of death, not the date you apply.

What is the Estate Information Return deadline?

It is due within 180 calendar days after the certificate is issued, even if the estate is $50,000 or less. Failing to file can carry a fine of at least $1,000 and up to twice the tax payable, up to two years' imprisonment, or both.

Do I have to act as executor at all?

No. A named executor is not required to act. If you are unsure, get advice before you start dealing with the estate.
