Key takeaways
  • An Ontario house owned by the deceased at death counts toward the value of the estate, at its appraised value at the date of death.
  • Only encumbrances on real property, such as a mortgage or lien, reduce the value; funeral costs, legal fees and credit card debt do not.
  • For current applications, the first $50,000 is exempt and the rest is taxed at $15 per $1,000 or part thereof.
  • A home that was jointly owned and passed automatically to another owner, or that was sold before death, is generally not counted.

If you are inheriting a house, one of the first surprises can be that the home is often the biggest piece of the estate, and it can drive the Estate Administration Tax. The tax is based on the value of what the person owned at death, not on what you personally receive.

This article explains how a family home is counted, how a mortgage changes the number, and what is not counted at all. Your own facts, such as how the home was owned, can change the result, so treat this as a starting point.

How the tax works in short

Estate Administration Tax is payable by the estate to the Crown in right of Ontario immediately upon the issuance of an estate certificate. An estate certificate includes a certificate of appointment of estate trustee, and that includes a small estate certificate.

For applications made on or after January 1, 2020, an estate valued at $50,000 or less is exempt. Above that, the tax is $15 for each $1,000, or part of $1,000, of the value over $50,000. Ontario also says values are rounded up to the nearest $1,000 before the calculation.

The tax is paid by the estate, not by the estate trustee personally, and the trustee is liable only in a representative capacity.

Is the house counted, and at what value?

Yes, in most cases. Ontario lists Ontario real estate among the assets included in the value of the estate, less encumbrances such as mortgages or liens, using the appraised value at the date of death. Value is fair market value at the date of death, supported by documents such as appraisals.

So the number that matters is not what the family paid for the home, and not what it later sells for. It is the value at the date of death, backed up by paperwork. In practice, that usually means getting an appraisal and keeping it with the estate records.

The estate value is built from the total property the deceased owned at death, as sworn or affirmed to the court registrar before a grant is issued.

How a mortgage changes the number

The estate value is the disclosed value less the actual value of encumbrances on real property. A mortgage or lien registered against the house reduces the value counted.

For example, imagine a home with a registered mortgage and nothing else in the estate, where the appraised value less the mortgage works out to $250,000. The tax on a $250,000 estate is $3,000. If the same home had no mortgage and the estate were $500,000, the tax would be $6,750.

Only encumbrances on real property count. Ontario says funeral expenses, lawyer fees, loans and interest, vehicle debt, credit card debt, real estate commissions, unregistered loans and lines of credit cannot be deducted. That means an unregistered line of credit does not lower the number, even though it is a real debt of the estate.

When the home may not be counted

Ontario's list of excluded assets includes assets owned before death but not at death, jointly owned assets that pass automatically to the other owner or owners, and real estate outside Ontario. A home sold before death, a home held jointly with a surviving spouse that passed to them directly, or a cottage in another province or country may therefore fall outside the calculation.

SituationCounted toward estate value?
Ontario house owned by the deceased alone at deathYes, at appraised value at date of death, less registered mortgages or liens
House jointly owned and passing automatically to the other ownerNo
Real estate outside OntarioNo
House sold before deathNo, because it was not owned at death
Unregistered line of credit or credit card debtCannot be deducted

Whether a particular home really passed automatically to a co-owner can depend on how title was held and on the facts. If ownership is unclear or disputed, it is worth confirming with a lawyer before you file.

What to do next

The tax is calculated and paid when the application is filed with the Superior Court of Justice, unless no tax is payable or a court orders deferral. If the exact value is not yet known, an estimate can be used for the deposit, and the deposit is credited against the tax. Where an estimate was used, the applicant gives an undertaking to file a sworn statement of the actual value and pay any shortfall within six months.

If the estate is large, the house is only partly paid off, or family members disagree about value, speaking with an estates lawyer or accountant can help you avoid errors that may need to be corrected later.

Frequently asked questions

Does the full value of the house count even if there is a mortgage?

No. The value is reduced by the actual value of encumbrances on real property, such as a mortgage or lien. Debts that are not registered against the property, such as credit cards or unregistered loans, cannot be deducted.

Can I deduct the cost of selling the house or the lawyer's fees?

No. Ontario says real estate commissions, lawyer fees and funeral expenses cannot be deducted from the estate value.

What if the house is worth less than $50,000?

An estate valued at $50,000 or less is exempt from the tax for applications made on or after January 1, 2020. The Estate Information Return is still required even when no tax is payable.

Do I need a Small Estate Certificate if the house is the only asset?

A Small Estate Certificate is available for estates valued up to $150,000, and larger estates use a certificate of appointment of estate trustee. Which one applies depends on the total estate value, so a lawyer can confirm.
