Key takeaways
  • The Estate Information Return is due within 180 calendar days after the estate certificate is issued.
  • Failing to file, or making false or misleading statements, can lead to a fine, imprisonment or both.
  • Filing late also removes the usual four-year limit on the Ministry of Finance reassessing the estate.

You are the estate trustee, probate was granted, and somewhere along the way the 180-day filing window for the Estate Information Return slipped past. It is a stressful moment, but it is also a common one, because the return arrives at the end of a long list of other estate tasks.

This article explains what the deadline is, what can happen when it is missed, and the practical steps most trustees take next. It describes how the rules generally work. Whether any penalty actually applies to your situation depends on the facts, and a lawyer or accountant can confirm that.

The deadline and who it applies to

The estate representative must file an Estate Information Return with the Ministry of Finance within 180 calendar days after the estate certificate is issued. If the last day falls on a weekend or holiday, the deadline moves to the next business day.

The return is required even when the estate is worth $50,000 or less and no tax is owed. The same is true for small estates: the return is due within 180 calendar days of receiving a Small Estate Certificate, even if the estate is under $50,000.

There is an exception. No return is required for succeeding estate trustee certificates or for estate trustee during litigation certificates.

What can happen if the return is late or wrong

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: the law describes a range of possible consequences, and how it applies to a particular missed date depends on the facts.

The second consequence is less visible. The Ministry of Finance may normally assess or reassess an estate's tax within four years after the day the tax was due. If a return was not filed on time, or a misrepresentation was made, the Ministry may assess or reassess at any time, with no four-year limit.

In other words, a late return keeps the estate open to review for longer. That can matter when you are trying to close the estate and distribute what remains.

Who bears the tax

The Estate Administration Tax is paid by the estate, not personally by the estate representative. That is a different question from the penalties above, which are aimed at the representative's failure to file or at false statements. If you are worried about your own exposure as trustee, especially if you have already distributed assets, ask a lawyer to review your position.

Fixing it: practical steps

The most direct fix is to file the return as soon as you can. Filing online is recommended, although the return can also be filed by mail, courier, fax or in person. The Ministry publishes a detailed guide for completing it.

The supporting records for the return must be kept for four years at the estate representative's principal place of business or residence.

If the Ministry reassesses the estate

If you receive a Notice of Assessment you disagree with, a Notice of Objection must be filed within 180 days from the day the Notice of Assessment was issued. Keep the notice and note its date the moment it arrives, since that date starts the clock.

If the assessment shows additional tax owing, speak with a lawyer or accountant before responding. How the Ministry deals with a particular late filing is not something a general article can predict.

What to do next

Frequently asked questions

You have 180 calendar days after the estate certificate is issued. If that day is a weekend or holiday, the deadline moves to the next business day.

Do I still file the return if no tax is owed?

Yes. Even when the estate is worth $50,000 or less and no tax is owed, the return must still be filed after the certificate is issued.

What is the maximum penalty for not filing?

A representative who fails to file 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. Whether and how that applies to a particular late filing depends on the facts.

Can the Ministry still review the estate years later?
