Probate Fees in Ontario: How Estate Administration Tax Is Calculated (and How to Reduce It)

In Ontario, "probate fees" are not really fees at all — they are a tax. Officially called the Estate Administration Tax (EAT), this is the amount an estate pays to the province when the estate trustee (executor) applies to the court for authority to administer a deceased person's estate. The tax is charged on the total value of the assets that pass under the will, and for larger estates it can run into the tens of thousands of dollars.

The good news: the rate is predictable, the first $50,000 of every estate is tax-free, and there are several legitimate ways to reduce what your estate will owe. Below is a plain-language breakdown of how the tax is calculated, when probate is required, and the planning strategies that can lower the bill — done properly, with advice.

The short answer: Ontario charges $0 on the first $50,000 of an estate and $15 per $1,000 (1.5%) on the value above $50,000. An $800,000 estate pays about $11,250 in Estate Administration Tax.

#What is probate, and what is the Estate Administration Tax?

Probate is the court process that confirms a will is valid and grants the estate trustee the legal authority to deal with the deceased's assets. In Ontario, the document the court issues is the Certificate of Appointment of Estate Trustee.

To obtain that certificate, the estate must pay the Estate Administration Tax under the Estate Administration Tax Act, 1998. People still call it the "probate fee," but it is a tax calculated on the value of the estate — not a flat filing charge.

One important point up front: EAT is completely separate from income tax. The deceased's final income tax return (and any tax owing on it) is a different obligation owed to the Canada Revenue Agency. The Estate Administration Tax is owed to the Ontario Ministry of Finance and is based on asset value, not income.

#How much are probate fees in Ontario?

The tax is charged on a two-tier basis:

• $0 on the first $50,000 of the estate's value, and
• $15 per $1,000 (i.e. 1.5%) on every dollar above $50,000.

Estates valued at $50,000 or less pay no Estate Administration Tax at all, and may qualify for Ontario's simplified Small Estate court process, which uses a shorter application.

#How is estate administration tax calculated?

The math is straightforward. Take the total value of the estate, subtract the first $50,000, divide the remainder by 1,000, and multiply by 15.

For an $800,000 estate, that is (800,000 − 50,000) ÷ 1,000 × 15 = $11,250.

Here are a few worked examples:

What's included in the estate's value?

EAT is calculated on the value of all assets that pass under the will and require probate, including:

• Ontario real estate, valued at fair market value, less any registered mortgage or encumbrance against it
• Bank accounts and cash
• Investments and non-registered securities
• Vehicles and other personal property
• Other assets that the estate trustee must administer

Assets that pass outside the will — such as property held in joint tenancy or accounts with a named beneficiary — generally are not counted, which is the foundation of most probate-reduction planning (more on that below).

The Estate Information Return

After the Certificate of Appointment is issued, the estate trustee must file an Estate Information Return with the Ministry of Finance within 180 days. This return itemizes the estate's assets and the values used to calculate the tax. Filing late or understating values can expose the trustee to penalties, so accuracy matters — keep appraisals, statements, and supporting documents.

#When is probate required in Ontario?

Not every estate needs probate, but it is commonly required when:

• The deceased owned real estate solely in their own name (not in joint tenancy with right of survivorship); or
• A bank or financial institution requires a Certificate of Appointment before it will release accounts or investments.

If all of the deceased's assets passed automatically by survivorship or beneficiary designation, probate may not be needed at all — and no Estate Administration Tax would be payable. For an estate where the person died without a will, probate (and the rules of intestacy) almost always come into play; see our guide on what happens when you die without a will in Ontario.

#How can I reduce probate fees in Ontario?

There are several legal ways to reduce or avoid Estate Administration Tax by keeping assets out of the estate that requires probate. Each comes with trade-offs, and none should be done without legal and tax advice — a do-it-yourself mistake can cost far more than the tax it was meant to save.

1. Joint ownership with right of survivorship

Property held in joint tenancy passes automatically to the surviving owner and falls outside the estate, so it is not subject to EAT.

Caution: joint ownership means giving up sole control of the asset during your lifetime, and it can create unintended family-law and tax consequences. Adding an adult child to title is especially risky: under Pecore v. Pecore, the law presumes a resulting trust, meaning the child may hold the asset for the estate rather than receive it as a gift — the opposite of what many people intend. Whether the asset truly passes to the child depends on evidence of intention.

2. Beneficiary designations

RRSPs, RRIFs, TFSAs and life insurance can name a beneficiary directly. On death, the proceeds pass straight to that person outside the estate, avoiding probate on those amounts.

Caution: designations must be kept current after marriage, divorce, or a beneficiary's death, and naming "the estate" as beneficiary (or leaving it blank) can pull the asset back into the probate calculation. Tax on registered plans can also still be owing on the final return even when the asset itself avoids probate.

3. Multiple wills

Business owners and others with private assets often use two wills: a primary will governing assets that need probate (real estate, bank accounts) and a secondary will for assets that typically do not require a court certificate — such as shares in a private corporation and personal effects. EAT is paid only on the assets governed by the will that is submitted for probate.

Caution: multiple wills must be drafted carefully so they don't accidentally revoke one another, and the strategy needs to fit your overall corporate and tax structure.

4. Inter vivos (living) trusts

Transferring assets into a living trust during your lifetime can remove them from your estate, so they pass under the trust rather than the will.

Caution: trusts carry setup and ongoing costs, their own tax rules, and a loss of direct control — they make sense only in the right circumstances.

5. Gifting during your lifetime

Giving assets away while you are alive reduces the value of your estate at death, and therefore the tax.

Caution: a completed gift is irrevocable, may trigger capital gains, and can affect your own financial security — give only what you can genuinely afford to part with.

The common thread: every one of these strategies trades the certainty and control of a simple will for tax savings, and several have tax or family-law side effects that can outweigh the probate they avoid. This is precisely the kind of planning where coordinated wills and estates advice pays for itself.

#A note on timing and cost

Estate Administration Tax is payable when the application for the Certificate of Appointment is submitted, and it is calculated on values as of the date of death. For real estate, that usually means a fair market value appraisal; for investments, date-of-death statements. Getting these values right protects the estate trustee and keeps the Estate Information Return defensible if the Ministry ever asks questions.

Remember, too, that EAT is only one of the costs of settling an estate. Legal fees, accounting fees, appraisals, and the final income tax owing to the Canada Revenue Agency are all separate. Planning that reduces the probate tax does not eliminate these other obligations — so the goal is an overall plan that is efficient across the board, not just on one line item.

It's also worth weighing simplicity against savings. A clean, well-drafted single will that goes through probate is often the right answer for a modest estate, because aggressive avoidance strategies can introduce control, tax, and family-law risks that outweigh a relatively small tax. The larger and more complex the estate — particularly where there is real estate, a private corporation, or blended-family considerations — the more a tailored plan tends to pay off.

#How a wills and estates lawyer helps

A good estates lawyer does more than fill in court forms. They help you structure your assets while you're alive to legitimately minimize EAT, draft primary and secondary wills where appropriate, keep beneficiary designations and ownership consistent with your plan, and guide your estate trustee through the application and the Estate Information Return after death — so the savings are real and the paperwork holds up.
