Key takeaways
  • A deposit refund goes through the Superior Court of Justice and only works if no certificate was issued, while tax already paid is refunded by the Ministry of Finance.
  • A tax refund needs an Estate Information Return filed within four years of the certificate, and the request must come within 12 years of issuance or two years of a Notice of Assessment.
  • Common causes of overpayment are wrong asset values and counting items that should have been left out, such as jointly held assets that pass to a surviving owner, or real estate outside Ontario, or not deducting a registered mortgage on Ontario real property.

Paying Estate Administration Tax can feel like a one-way street. But sometimes an estate pays more than it should, or an application is withdrawn after money has already gone in. If you are the estate trustee, it helps to know that a refund may be possible. Where you ask depends on whether a certificate was ever issued, and a refund of tax already paid also depends on an Estate Information Return filed within four years of the certificate and on the 12-year and two-year request limits.

This article explains the difference between the deposit paid at filing and the tax itself, who you ask for each kind of refund, the conditions and time limits, and the mistakes that most often lead to overpayment. Every estate is different, so a lawyer or accountant can confirm how this applies to yours.

Deposit or tax: why the difference matters

The tax is paid as a deposit when the probate application is filed with the court. Once the probate certificate is issued, that deposit becomes the Estate Administration Tax. The tax is charged only when an estate certificate is applied for and issued, so if no certificate is issued, no tax is owed.

That is why the stage you are at decides everything. Before a certificate is issued you are dealing with a deposit. After it is issued you are dealing with tax that has already been paid. The estate pays the tax, not you personally as the estate representative.

Who you ask for the refund

SituationWhere to ask
Deposit paid, no certificate issued (for example, the application was withdrawn)Superior Court of Justice
Tax already paid after the certificate was issuedMinistry of Finance, not a courthouse

A deposit refund is available only if no certificate has been issued. If a certificate has been issued, the courthouse is not the place to ask. The request goes to the Ministry of Finance instead.

Conditions and time limits for a tax refund

A refund of tax already paid requires that an Estate Information Return was filed within four years of the certificate. The request itself must be made within 12 years of issuance or within two years of a Notice of Assessment.

The return is due within 180 calendar days after the certificate is issued. If that deadline falls on a weekend or holiday, it moves to the next business day. Filing online is recommended, though mail, courier, fax and in-person filing are also possible. Even where the estate is worth $50,000 or less and no tax is owed, the return must still be filed.

If the Ministry reassesses the estate and you disagree, a Notice of Objection must be filed within 180 days from the day the Notice of Assessment was issued.

How an overpayment can happen

For certificates applied for on or after January 1, 2020, there is no tax on an estate worth $50,000 or less. Above that, the tax is $15 for every $1,000 (or part of $1,000) over $50,000, and the estate's value is rounded up to the nearest thousand dollars. Because each $1,000 costs $15, an error in value can add up. Common causes include:

Be careful in the other direction too. Only encumbrances on real property can be deducted. Funeral expenses, lawyer's fees, loans, credit card debt and real estate commissions do not reduce the value. And a tenant in common's share does not pass automatically to the other owners: it becomes part of their estate, so it counts toward the estate's value if probate is sought.

Correcting the return and keeping records

If information in a filed return turns out to be incorrect or incomplete, an amended return must be filed within 60 days of becoming aware of it. This duty applies within four years of the certificate being issued. Where an estimated value was used on the application, an amended return is due within 60 days after the actual value is given to the court.

Estate representatives must be able to back up asset values with documents such as statements or an appraiser's opinion of value. The records supporting the return must be kept for four years at the representative's principal place of business or residence.

Keep in mind that a correction can go either way. The Ministry may assess or reassess within four years after the tax was due. If a return was late or a misrepresentation was made, there is no four-year limit. A failure to file, or false or misleading statements, can lead to a fine of at least $1,000 and up to twice the tax payable, imprisonment of up to two years, or both.

What to do next

Frequently asked questions

Can I get my probate deposit back if I withdraw the application?

A deposit refund is requested from the Superior Court of Justice, and only if no certificate has been issued. Once a certificate is issued, the deposit has become the tax and a different process applies.

Where do I ask for a refund of tax already paid?

You ask the Ministry of Finance, not a courthouse. You need an Estate Information Return filed within four years of the certificate.

How long do I have to request a tax refund?

The request must be made within 12 years of the certificate being issued or within two years of a Notice of Assessment. The return must also have been filed within four years of the certificate.

Who pays the tax, and who gets the refund?

The tax is paid by the estate, not by the estate representative personally. How a refund is dealt with among beneficiaries depends on the facts, so it is worth confirming with a lawyer.
