Key takeaways
  • The Estate Information Return is due within 180 calendar days after the estate certificate is issued, even if the estate is worth $0.
  • If you learn the return is wrong or incomplete, you must file an amended return within 60 days of finding out.
  • Failing to file, or making a false or misleading statement, is an offence that can bring a fine, imprisonment, or both.

If you have been named estate trustee, getting the certificate from the court can feel like the finish line. It is not. Ontario also expects you to report on the estate to the Ministry of Finance after the certificate is issued.

This article explains the filing deadline, what to do if the return turns out to be wrong, and the consequences of filing late or inaccurately. Every estate is different, so a lawyer or accountant can confirm how this applies to yours.

What the Estate Information Return is

For estate certificate applications made on or after January 1, 2013, the estate representative must give the Minister information about the deceased's estate, within the time and in the manner the Minister of Finance prescribes. In practice, this is the Estate Information Return.

It is separate from paying Estate Administration Tax. The tax is a payment based on the value of the estate, while the return is a report about the estate. You can have to deal with both, and each has its own rules.

The 180-day deadline

The estate representative must file the return with the Ministry of Finance within 180 calendar days after the estate certificate is issued. This applies even if the estate is worth $0.

Small estates are not excused. For applications made on or after January 1, 2020, no Estate Administration Tax is payable on estates worth $50,000 or less. Even so, the return must still be filed within 180 calendar days of receiving the certificate, and that includes a Small Estate Certificate.

There are limited exceptions. No tax is owed and no return is required for certain succeeding estate trustee certificates or a Certificate of Appointment of Estate Trustee During Litigation. If no certificate is issued, no tax is owed and the deposit is refunded.

Fixing a return that was wrong or incomplete

Mistakes happen, especially when assets surface late. If the representative learns that a return is wrong or incomplete, they must file an amended return within 60 days of finding out. A newly found asset is reported at its fair market value on the date of death.

Estimates need extra care. If the deposit was based on an estimated estate value, the applicant must give an undertaking. They must then file a sworn statement of the actual value and pay any extra tax within six months after giving the undertaking.

Penalties and time limits

Failing to comply with the return requirement is an offence, and so is making a false or misleading statement in the return. Where the tax payable exceeds $1,000, the fine is at least $1,000 and up to twice the tax payable. The penalty can also be up to two years' imprisonment, or both.

For the false or misleading statement offence, the Act includes a due-diligence exception. Whether it could help in a given case depends on the facts, so get advice early rather than relying on it.

There is also a long reach-back. The Minister may assess or reassess Estate Administration Tax within four years after the day the tax became payable. If a person failed to file the return, made a misrepresentation or committed fraud, the Minister can assess at any time.

SituationConsequence

False or misleading statementOffence, subject to a due-diligence exception
Tax payable over $1,000Fine of at least $1,000 and up to twice the tax
Return filed correctlyOrdinary four-year assessment period

What to do next

Treat the return as part of the estate's to-do list from the day the certificate arrives. Gather bank statements, property records and account balances early, so the values you report can be backed up later.

Do I file a return if the estate is under $50,000?
