Key takeaways
  • Only mortgages, liens and similar encumbrances on real property can be deducted, and only from that property's value.
  • Funeral expenses, legal fees, credit card debt, lines of credit and other loans cannot be deducted from the estate value.
  • Assets are valued at fair market value on the date of death, supported by documents.

Many people assume that if the deceased owed money, the debts come off the estate before probate tax is calculated. In Ontario, that is true for only a narrow category of debt.

Below is how the Estate Administration Tax treats mortgages and other debts, how the estate value is set, and what to do if you cannot pay the tax at filing. It is general information, and a lawyer or accountant can confirm how it applies to your estate.

The rule on deductions

Only mortgages, liens and similar encumbrances on real property can be deducted, and only from that property's value. A mortgage on one property does not reduce the value of the bank accounts, investments or any other property.

For Ontario real estate, the tax is based on its value less mortgages or liens on it.

What can and cannot be deducted

ItemReduces the estate value?
Mortgage on real propertyYes, only from that property's value
Lien or similar encumbrance on real propertyYes, only from that property's value
Funeral expensesNo
Legal feesNo
Loans and interestNo
Vehicle debtNo
Credit card debtNo
Lines of creditNo
Unregistered loansNo
Real estate commissionsNo

The estate still has to deal with these debts. Estate trustees pay taxes, bills and other debts as part of winding up the estate. They just do not lower the value used for the tax.

How the estate value is set

The tax is based on the value of all assets the deceased owned at the time of death, including Ontario real estate, bank accounts, investments, vehicles, business interests and insurance paid to the estate. Assets are valued at fair market value on the date of death.

Real estate is valued at its appraised value on the date of death, even if it later sells for more or less. Values must be supported by documents such as account statements or an appraiser's opinion, and a business may need a professional appraiser.

Some assets are left out entirely, including jointly held assets that automatically pass to the other owner and real estate outside Ontario.

For estates over $50,000, the tax is $15 for every $1,000, or part of $1,000, above the first $50,000. The value is rounded up to the nearest $1,000. Ontario's own example is a $240,000 estate: the first $50,000 is taxed at $0, the remaining $190,000 is taxed at $15 per $1,000, and the tax is $2,850.

If you cannot pay or do not yet know the value

The tax is paid when the application is filed, by certified cheque or bank draft payable to the 'Minister of Finance'. Two options exist in some situations.

If new assets turn up after the certificate is issued, an amended Estate Information Return is due within 60 days of becoming aware, and any extra tax is payable.

What to do next

Frequently asked questions

Can I deduct funeral expenses?

No. Funeral expenses cannot be deducted from the estate value for the Estate Administration Tax. The same goes for legal fees and real estate commissions.

Does a mortgage reduce the value of the whole estate?

No. A mortgage can only be deducted from the value of the real property it is registered against. It does not reduce the value of other assets.

What about real estate in another province?

Real estate located outside Ontario is not included in the estate value for Ontario's tax. A lawyer can confirm how any other jurisdiction treats it.

What if the estate's value changes after the certificate?

If the representative finds new assets or learns the return was incorrect or incomplete, they must file an amended Estate Information Return within 60 days of becoming aware. Any extra tax is then payable.
