  • Ontario charges no Estate Administration Tax on the first $50,000 of estate value.

When a loved one dies, the family often discovers that accessing estate assets — bank accounts, real estate, investments — requires a court-issued certificate. Applying for that certificate triggers Ontario's Estate Administration Tax (EAT), commonly called "probate fees." For many families, this is their first encounter with the cost of settling an estate, and the bill can be significant.

This article explains how the Estate Administration Tax is calculated, what the first-$50,000 band means for estates in Ontario, and what executors need to know before filing an application with the court.

What Is the Estate Administration Tax?

The Estate Administration Tax is a provincial tax imposed under Ontario's Estate Administration Tax Act. It is collected when an executor (formally called an estate trustee) applies to the Superior Court of Justice for a Certificate of Appointment of Estate Trustee — the document the public and financial institutions commonly call a "probate certificate" or "letters probate."

The tax is based on the value of the estate that passes through the will (or through an intestacy). Assets that bypass probate — such as jointly held property or accounts with named beneficiaries — are generally not included in the calculation (more on that in a moment).

How the Tax Is Calculated

Ontario calculates the tax in two parts:

Above the first $50,000, the rate is $15 for every $1,000 or part of $1,000, set in the Estate Administration Tax Act itself.

A Simple Example (Illustrative Only)

Suppose the estate's gross value subject to probate is $400,000. No tax applies to the first $50,000, and the remaining $350,000 is taxed at $15 for every $1,000, so the tax is $5,250. The resulting tax is payable at the time the application is filed, and the court will not issue the certificate until the tax is paid or an appropriate arrangement is made.

What "First $50,000" Means

Ontario charges no Estate Administration Tax on the first $50,000 of estate value. This benefits smaller and mid-sized estates disproportionately. However, a few important points:

  1. The $50,000 threshold is set in the Estate Administration Tax Act.
  2. No tax applies to that first $50,000; the $15 rate applies only to the value above it.
  3. For estates of $50,000 or less, no EAT is payable, but an application may still be necessary to unlock assets held solely in the deceased's name.

What Assets Are Included in the Estate Value?

Not every asset a person owned is counted in the probate estate value. The estate trustee must include:

What Assets Are Excluded?

Several asset classes do not flow through the estate and are therefore not counted for EAT purposes:

These exclusions are a major reason estate planning often focuses on structuring assets to bypass probate — covered in more detail in other articles in this series.

Valuing the Estate for the Application

The court requires the estate trustee to state the gross value of the estate as of the date of death. This is not net value: debts and liabilities are not deducted for EAT purposes, except that a mortgage or other encumbrance on real estate is deducted from that property's value.

Valuation challenges arise with:

Providing an inaccurate value — even inadvertently — can lead to penalties (discussed further in a companion article). Erring on the side of accuracy and seeking professional guidance on difficult-to-value assets is strongly recommended.

When Is the Tax Paid?

The EAT is paid to the government when the estate trustee files the application for a Certificate of Appointment. No certificate is issued until the tax is remitted or an arrangement is accepted. The estate (not the executor personally) pays the tax, but the executor is responsible for ensuring the correct amount is calculated and submitted.

Frequently asked questions

Does every estate in Ontario need to go through probate?

Not always. If all assets either pass by right of survivorship, have named beneficiaries, or can be transferred without a court certificate, probate may be avoidable. However, real estate held solely in the deceased's name almost always requires probate.

Can the executor be personally liable for the Estate Administration Tax?

The tax is an obligation of the estate. However, if an executor distributes estate funds before paying all debts and taxes and the estate becomes insolvent as a result, the executor may face personal liability. Always pay the EAT before distributing to beneficiaries.

Is the Estate Administration Tax the same as income tax on the estate?

No. The EAT is a provincial government tax on the privilege of obtaining a Certificate of Appointment. It is separate from the terminal income tax return filed for the deceased, and from any income earned by the estate after death.

What happens if the estate value changes after the application is filed?

Ontario has an Estate Information Return process that requires the executor to confirm or correct the estate value within a prescribed period after the certificate is issued. If the value turns out to be higher, additional tax will be owed.
