Key takeaways
  • The tax is based on the value of all assets the deceased owned at death, valued at fair market value on the date of death.
  • Only mortgages, liens and similar encumbrances on real property can be deducted, and only from that property.
  • The Estate Information Return lists each asset and its date-of-death value, and is due within 180 calendar days after the certificate issues.

If you are the estate trustee, you must state the estate's value when you apply for a certificate, and later report each asset on a return. Getting the value right matters because the tax depends on it and mistakes can be costly.

This article explains what goes into the value, what stays out, and how to support the numbers for a house, investments, vehicles and a business.

What counts toward the estate's value

The tax is based on the value of all assets the deceased owned at the time of death. That includes:

The value matters because it sets the tax. For certificates applied for on or after January 1, 2020, there is no tax on the first $50,000, and above that the tax is $15 for every $1,000, or part of $1,000. The value is rounded up to the nearest $1,000, so for a $240,000 estate the tax is $2,850. Estates worth $50,000 or less pay no tax, but if a certificate is issued an Estate Information Return must still be filed.

What can be left out

Several assets are not part of the value for the tax:

Whether a particular asset is truly joint with survivorship, or has a valid designation, can depend on how it is held and on the paperwork. If it is unclear, a lawyer can confirm.

Some certificates are treated differently. For a certificate limited to the assets covered by one will, or in resealing cases, only the assets within that certificate's scope are counted, and certain property on a Reserve may be exempt. Some certificates, such as a Certificate of Appointment of Estate Trustee During Litigation, require no tax or Estate Information Return.

How to value each type of asset

Assets are valued at fair market value on the date of death. Values must be supported by documents such as account statements or an appraiser's opinion.

AssetApproach
House or other Ontario real estateAppraised value on the date of death, even if it later sells for more or less. Mortgages and liens on that property can be deducted from its value.
Investments and bank accountsSupport the value with account statements.
Vehicles and vesselsIncluded wherever located. Valued at fair market value on the date of death.
A businessA complex asset, so a professional appraiser may be needed.

Ask each financial institution for statements showing the balance on the date of death, and keep them with your records.

What you cannot deduct

Only mortgages, liens and similar encumbrances on real property can be deducted, and only from that property's value. Funeral expenses, legal fees, loans and interest, vehicle debt, credit card debt, lines of credit, unregistered loans and real estate commissions cannot be deducted from the estate value.

This surprises many trustees. An estate with large debts other than a mortgage can still have a high value for tax purposes.

Reporting, corrections and what to do next

The estate representative must file an Estate Information Return with the Ministry of Finance within 180 calendar days after the certificate is issued. It lists each asset and its date-of-death value, and must be filed even if the estate value is $0.

The tax is paid as a deposit when the application is filed with the Superior Court of Justice, and the estate pays it, not the representative personally. In some cases an applicant can pay on an estimated value that they swear or affirm, and must then file a sworn statement of the total value and pay any balance owing within six months after giving the undertaking.

If you find new assets, or learn the return was incorrect or incomplete, you must file an amended return within 60 days of becoming aware, and any extra tax is then payable. Keep records for four years. Failing to file, or making false or misleading statements, can lead to a fine of at least $1,000 and up to twice the tax payable, and possibly imprisonment.

Frequently asked questions

What date is used to value the estate?

Assets are valued at fair market value on the date of death. A house is valued at its appraised value on that date, even if it later sells for more or less.

Can I deduct funeral costs and debts?

Generally no. Funeral expenses, legal fees, credit card debt, lines of credit and similar items cannot be deducted. Only mortgages, liens and similar encumbrances on real property can be deducted, from that property only.

Do I need an appraiser for a business?

For complex assets such as a business, a professional appraiser may be needed. Values must be supported by documents.

What if I find another asset later?

File an amended Estate Information Return within 60 days of becoming aware of it, and pay any extra tax. A lawyer or accountant can help you work out the right value.
