Key takeaways
  • Failing to file the return, or making false or misleading statements, can lead to a fine of at least $1,000 and up to twice the tax payable, up to two years in prison, or both.
  • If the return was late or a misrepresentation was made, the Ministry of Finance can reassess at any time, with no four-year limit.
  • An incorrect or incomplete return must be amended within 60 days of becoming aware of the problem.

You are the executor and something went wrong with the Estate Information Return. Perhaps the 180-day period passed, or you found that a value or an asset was missed. It is stressful, but the first step is usually to understand the deadlines and fix the return promptly.

This article outlines the penalties that exist, how long the Ministry of Finance can look back, and how corrections and objections work. What applies to your situation depends on the facts, so a lawyer or accountant can help.

The penalties on paper

An estate representative who fails to file the return, or who makes 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.

The word "may" matters, because it describes what can happen rather than what always will. How this applies to your situation depends on the facts, so it is worth confirming with a lawyer. Even so, the safest course is to deal with the problem as soon as you know about it.

The filing duty applies even when no tax is owed, because a return is still required for an estate worth $50,000 or less. The original deadline is 180 calendar days after the certificate is issued.

How long the Ministry can look back

The Ministry of Finance may assess or reassess an estate's tax within four years after the day the tax was due. That limit does not protect a late or misleading filing: if a return was not filed on time or a misrepresentation was made, the Ministry may assess or reassess at any time.

Return filed on time, no misrepresentationWithin four years after the day the tax was due
Return late or misrepresentation madeAt any time

This is a good reason not to leave a late return unfiled.

Correcting the return

The rules set out specific correction deadlines. Which one applies depends on what happened:

The correction period in each of these cases is 60 days. If a filing deadline falls on a weekend or holiday, it moves to the next business day. If a correction raises the estate's value, additional tax can be paid to the Superior Court of Justice or the Ministry of Finance, together with an affidavit setting out the revised value of the estate at the time of death.

Disputing an assessment or asking for a refund

If you disagree with an assessment, a Notice of Objection must be filed within 180 days from the day the Notice of Assessment was issued.

Refunds work differently depending on the stage. Deposit refunds are requested from the Superior Court of Justice, and only if no certificate has been issued. Refunds of tax already paid are requested from the Ministry of Finance, not at a courthouse. A tax refund requires an Estate Information Return filed within four years of the certificate, and the request must be made within 12 years of issuance or two years of a Notice of Assessment.

The tax is paid by the estate, not personally by the estate representative. Whether an executor could face personal exposure in other ways, for example after distributing assets, depends on the facts and is worth raising with a lawyer.

What to do next

Frequently asked questions

What is the maximum fine for not filing?

A fine of at least $1,000 and up to twice the tax payable by the estate may be imposed, and imprisonment for up to two years is also possible, or both. Note that $1,000 is the minimum fine, not the maximum, and these consequences apply to failing to file or to false or misleading statements.

Is there a time limit on the Ministry reassessing a late return?

Normally the Ministry may reassess within four years after the day the tax was due. For a late return or a misrepresentation there is no such limit.

I found an asset after I filed. What do I do?

An amended return listing the newly discovered property is due within 60 days after the statement of that property is delivered to the court.

How long do I have to object to an assessment?

A Notice of Objection must be filed within 180 days from the day the Notice of Assessment was issued.
