Key takeaways
  • Using the small estate process does not remove Estate Administration Tax on value over $50,000.
  • An Estate Information Return is still due within 180 calendar days of receiving a Small Estate Certificate, even if no tax is owed.
  • If new assets push the total over $150,000, a Certificate of Appointment of Estate Trustee must be applied for instead.

If you are handling an Ontario estate that is modest in size, you may have heard that a simpler court process exists. It does, and it can make the paperwork lighter. A common worry is whether it also makes the probate tax disappear.

This article explains how Estate Administration Tax works when you use the small estate process, what you file and how you pay, and what still has to be done after the certificate is issued.

Does the small estate process remove the tax?

No. Since April 1, 2021, a small estate for probate purposes is one valued at $150,000 or less. Small estates still pay Estate Administration Tax on the value over $50,000, up to the $150,000 cap.

The tax is only charged when an estate certificate is applied for and issued. If no certificate is applied for or issued, no tax is owed. A Small Estate Certificate is an estate certificate, so the tax rules apply to it in the same way.

The tax is paid by the estate, not personally by the estate representative. In practice, that means it is a cost of the estate rather than something you cover from your own pocket.

How the tax is calculated

For certificates applied for on or after January 1, 2020, no tax is payable on an estate worth $50,000 or less. Above $50,000, the tax is $15 for every $1,000 (or part thereof) of the estate's value over $50,000. The estate's value is rounded up to the nearest thousand dollars before you calculate.

So the steps are: work out the estate's value, round it up to the next thousand, subtract $50,000, and apply the rate to each $1,000 of what remains. A lawyer or accountant can confirm your figure before you file.

What counts toward the value matters. Examples of what is generally included or left out:

Assets are valued at fair market value at the time of death, and you should be able to support your figures with documents such as statements or an appraiser's opinion.

The forms and how to pay

The small estate application is Form 74.1A, filed with Form 74.1B, together with a draft Small Estate Certificate (Form 74.1C).

The tax is paid when the application is filed, unless it is not payable or the court orders it deferred. Whether deferral could apply to you is a question for a lawyer.

At the court office, the tax can be paid by:

Cheques and drafts are made payable to "Minister of Finance".

The Estate Information Return is still required

An Estate Information Return must be filed within 180 calendar days of receiving a Small Estate Certificate, even if the estate is under $50,000 and no tax is owed. It is filed with the Ministry of Finance.

If the deadline falls on a weekend or holiday, it moves to the next business day. Filing online is recommended, though mail, courier, fax or in person are also options.

Keep the records that support the return for four years at your principal place of business or residence. Failing to file, or making false or misleading statements, can lead to a fine of at least $1,000 and up to twice the tax payable, imprisonment for up to two years, or both.

If you later learn the return is incorrect or incomplete, an amended return must be filed within 60 days of becoming aware of it, and this duty applies within four years of the certificate being issued.

What if new assets turn up?

If assets are found after the certificate is issued, the answer depends on the new total. If it is still $150,000 or less, the estate can apply for an Amended Small Estate Certificate (Form 74.1E). If the total goes over $150,000, a Certificate of Appointment of Estate Trustee must be applied for instead.

An amended Estate Information Return listing the newly discovered property is due within 60 days after the statement of that property is delivered to the court. Additional tax found to be owing can be paid to the Superior Court of Justice or the Ministry of Finance, with an affidavit setting out the revised value of the estate at the time of death.

What to do next

If the estate is close to the limit, includes jointly held or foreign property, or you are unsure what counts, a lawyer or accountant can help you confirm the value before you file.

Frequently asked questions

Do I pay probate tax on a small estate certificate if the estate is under $150,000?

Possibly. Estates of $50,000 or less owe no tax. Above that, tax is still charged on the value over $50,000, up to the $150,000 cap.

Do I have to file an Estate Information Return if no tax is owed?

Yes. It must be filed within 180 calendar days of receiving a Small Estate Certificate, even if the estate is under $50,000 and no tax is owed.

Am I personally responsible for paying the tax?

The tax is paid by the estate, not personally by the estate representative. Whether other responsibilities arise, for example around distributions, is worth confirming with a lawyer.

What if I find more assets after the certificate is issued?

If the new total is still $150,000 or less, you can apply for an Amended Small Estate Certificate using Form 74.1E. If it goes over $150,000, you must apply for a Certificate of Appointment of Estate Trustee instead.
