Key takeaways
  • The Estate Information Return is due to the Ministry of Finance within 180 calendar days after the certificate is issued, even if the estate value is $0.
  • An amended return may be needed within 60 days when information was wrong, assets were missed or an estimated value is replaced by the actual one.
  • Failing to file or filing false or misleading statements can bring a fine of at least $1,000 and up to twice the tax, imprisonment, or both.
  • The Ministry can reassess without a time limit if a required filing was missed.

Getting the certificate of appointment feels like the finish line, but for Ontario executors there is one more filing: the Estate Information Return. It is easy to overlook because it comes after probate, and the deadline runs on its own clock.

This article covers when the return is due, what it generally reports, when you may need to correct it, and what can happen if it is missed. It is general information and not a substitute for advice about your estate.

What the return is and who must file it

When you apply for a certificate, you pay estate administration tax as a deposit, and it becomes the tax once the certificate is issued. The Estate Information Return is a separate filing with the Ministry of Finance, made by the estate's representative after the certificate is issued.

It is required even for small estates. An estate valued at $50,000 or less pays no tax but must still apply for the certificate and file the return. A small estate certificate does not remove the obligation either; the return is still due within 180 calendar days of the certificate.

The 180-day deadline

The return must be filed with the Ministry of Finance within 180 calendar days after the certificate is issued, even if the calculated value of the estate is $0. If the due date falls on a weekend or holiday, it moves to the next business day.

Calendar days include weekends and holidays, so count carefully from the date on the certificate and mark the due date in your calendar as soon as it is issued. The date probate is issued, not the date of death, starts the clock.

What to include

The return deals with the value of the estate for tax purposes, so it follows the same rules as your application. The value is measured in Canadian dollars at the date of death. Your return should be consistent with the values you gave in Form 74A, which asks for real property, personal property and total estate value.

If you paid tax on an estimated value, you must file a sworn statement of the total value within six months and pay any balance owing. Ask a lawyer or accountant to review the figures if the estate holds anything unusual.

When you need to file an amended return

Filing once is not always the end. An amended return is required in these situations:

SituationAmended return due
Incorrect or incomplete informationWithin 60 days of becoming aware of the problem, and within four years of the certificate being issued
New assets discoveredWithin 60 days after the statement is delivered to the court
An estimated value was usedWithin 60 days of the actual value being shared with the court

Penalties for missing the deadline or misreporting

A representative who fails to file, or who files false or misleading statements, may be fined at least $1,000 and up to twice the tax payable by the estate, imprisoned for up to two years, or both.

There is also a long-term risk. The Ministry may reassess the tax within four years after it was due, but it may assess or reassess at any time if a required filing was missed or there was misrepresentation or fraud. Late filing can therefore stay with an estate for many years.

What to do next

Frequently asked questions

Do I still file the return if the estate owes no tax?

Yes. The return must be filed within 180 calendar days of the certificate even if the calculated value of the estate is $0. Estates of $50,000 or less pay no tax but must still file.

What if day 180 is a Saturday?

If the due date falls on a weekend or holiday, it moves to the next business day.

Can I fix a mistake after filing?

Generally yes, through an amended return. For incorrect or incomplete information, it is due within 60 days of becoming aware of the problem and within four years of the certificate being issued.

What is the penalty for not filing?

A fine of at least $1,000 and up to twice the tax payable, imprisonment up to two years, or both. What a court would actually decide depends on the facts, so get advice if you are late.
