The Ontario estate administration tax is 1.5% of the value of an estate above $50,000, which works out to $15 for every $1,000 over that threshold. Estates worth $50,000 or less pay nothing. The tax is collected by the Superior Court of Justice when the estate trustee applies for probate (formally, a Certificate of Appointment of Estate Trustee), and the current rate has applied to applications filed on or after January 1, 2020 under the Estate Administration Tax Act, 1998.1Government of Ontario. Estate Administration Tax Act 1998, S.O. 1998, c. 34, Sched.
How to Calculate the Tax
Take the total value of the estate, subtract $50,000, and multiply what’s left by 0.015. Ontario rounds the estate value up to the nearest thousand before doing the math, so an estate worth $239,250 is treated as $240,000.2Government of Ontario. Estate Administration Tax
Some worked numbers:
- A $100,000 estate has $50,000 above the threshold. Tax owed: $750.
- A $240,000 estate has $190,000 above the threshold. Tax owed: $2,850.
- A $550,000 estate has $500,000 above the threshold. Tax owed: $7,500.
- A $1,000,000 estate has $950,000 above the threshold. Tax owed: $14,250.
What Counts in the Estate Value
The tax applies to the fair market value of every asset that passes through probate, measured as of the date of death. Fair market value is what a willing buyer would pay a willing seller in an open market. For real estate, bank accounts, vehicles, investment portfolios, and business interests, you need documentation tied to that date: bank statements around the date of death, appraisals for real estate or unusual property.
Real estate is included at market value, but debts registered as a charge against the land come off. A home worth $600,000 with a $200,000 mortgage contributes $400,000 to the estate value. A home equity line of credit secured by the property works the same way.
Solely held bank and investment accounts are included at their date-of-death balance, including any accrued interest, because the financial institution won’t release the funds without a court certificate.
Unsecured Debts Do Not Reduce the Tax
Credit card balances, car loans, student debt, investment loans, personal loans, and tax arrears cannot be subtracted from the estate value. The only deduction is for debts registered as a charge against Ontario real estate. An estate with $500,000 in assets and $80,000 in unsecured debt still pays tax on the full $500,000.2Government of Ontario. Estate Administration Tax Executors often expect a net-value calculation and are surprised by this.
Assets That Stay Out of the Estate
Several categories of property pass directly to a surviving person without going through probate, and none of them count toward the tax:
- Property held in joint tenancy with right of survivorship, including jointly held bank accounts and homes registered in joint names, transfers automatically to the surviving co-owner.
- Registered Retirement Savings Plans, Tax-Free Savings Accounts, and Registered Retirement Income Funds with a named beneficiary pay out to that person directly.
- Life insurance proceeds go straight to a named beneficiary, provided the policy names a specific person rather than “the estate.”
Sorting assets into what does and doesn’t pass through probate is the biggest factor in what the final tax bill looks like.
Ways to Reduce the Tax
Because the 1.5% rate ignores unsecured debts and applies to gross value, the bill on a larger estate can reach tens of thousands of dollars. A few planning approaches are common.
Joint Ownership
Adding a spouse or adult child as a joint tenant on an account or a property title moves that asset outside the estate on death. The tradeoffs are real: the co-owner gains immediate legal rights during your lifetime, the transfer can trigger land transfer tax or capital gains consequences depending on the asset, and the property becomes exposed to the co-owner’s creditors.
Beneficiary Designations
Naming a specific beneficiary on RRSPs, TFSAs, RRIFs, and life insurance keeps those funds out of the estate. If the beneficiary field is blank or names “my estate,” the proceeds fall back into the probatable pool. Designations should be reviewed after major life events like a divorce.
Multiple Wills
Ontario permits two separate wills: a primary will covering assets that need probate (real estate, publicly traded investments, bank accounts) and a secondary will covering assets that don’t (private company shares, partnership interests, personal effects like jewelry or art). Only the primary will is submitted to the court, so only its assets attract the tax. This matters most for business owners whose private company shares represent a large slice of their wealth.
The Small Estate Certificate
Since April 1, 2021, estates valued at $150,000 or less can use a simplified probate process and apply for a Small Estate Certificate instead of a full Certificate of Appointment. The tax rules are the same: nothing on the first $50,000, and 1.5% on the amount above that, paid when the application is filed.3Government of Ontario. Probate of a Small Estate
How and When You Pay
The tax is paid to the Superior Court of Justice at the time the probate application is filed, typically by certified cheque or bank draft payable to the Minister of Finance. The court will not process the application without full payment unless a deferral is granted.2Government of Ontario. Estate Administration Tax The application separates real estate from personal property, and values need to be supported with documentation such as bank statements near the date of death and professional appraisals where appropriate.4Ontario Court Services. Estate Forms under Rule 74, 74.1 and 75 of the Rules of Civil Procedure
The Estate Information Return
After the certificate is issued, the estate representative has 180 calendar days to file an Estate Information Return with the Ministry of Finance. The return sets out each asset and its value so the Ministry can confirm that the correct tax was paid.5Ministry of Finance. Guide Estate Information Return Estate Administration Tax Act, 1998 Estates of $50,000 or less that owe no tax still have to file.2Government of Ontario. Estate Administration Tax Filing late, filing nothing, or filing false or misleading information is an offence carrying a fine of at least $1,000 (or up to twice the tax payable, whichever is greater), imprisonment for up to two years, or both.1Government of Ontario. Estate Administration Tax Act 1998, S.O. 1998, c. 34, Sched.
Corrections and Refunds
If the return turns out to be wrong or incomplete within four years of the certificate being issued, an amended return has to be filed within 60 calendar days of finding the problem. After four years there is no obligation to correct it, and issuing a revised or succeeding certificate does not restart that four-year clock.5Ministry of Finance. Guide Estate Information Return Estate Administration Tax Act, 1998 The same 60-day window applies when the estate later pays additional tax, receives a refund, or discovers property that wasn’t on the original return.
Refunds are available where asset values were initially overstated. To qualify, the Estate Information Return must have been filed within four years of the certificate, and the written refund request has to reach the Ministry of Finance within 12 years of the certificate date, or within two years of a Notice of Assessment, whichever applies.5Ministry of Finance.

Federal Taxes Are Separate
The estate administration tax is a provincial charge and does not cover the deceased’s federal income tax, GST/HST, or related amounts. Before distributing assets, the estate representative should apply to the Canada Revenue Agency for a clearance certificate confirming those federal amounts are settled. Distributing without one leaves the representative personally liable for any unpaid federal tax, up to the value of the assets already handed out.6Canada Revenue Agency.
