When someone dies owning property in Ontario, two very different numbers get calculated, often within the same few months, and it's easy to assume they're the same figure used twice. They're not. The value used for Estate Administration Tax and the value used to calculate deemed disposition capital gains are calculated under different laws, for different purposes, and can genuinely differ.
Knowing which value applies to which filing — and who you're actually filing with — is one of the first things an estate trustee needs to sort out.
Two Values, Two Purposes
| Estate Administration Tax value | Deemed disposition value | |
|---|---|---|
| Governed by | Ontario's Estate Administration Tax Act | Canada's Income Tax Act (federal) |
| Purpose | Calculates the provincial tax paid when applying for an estate certificate | Calculates capital gains (or losses) reportable on the deceased's final tax return |
| What's typically included | Assets that require an estate certificate to be dealt with | Generally, all capital property the deceased owned, however it passes on death |
| What's typically excluded | Assets with a named beneficiary (RRSPs, RRIFs, life insurance) and jointly held assets that pass by survivorship | A principal residence that qualifies for the principal residence exemption; property that rolls over to a spouse or qualifying trust |
| Filed with | The Ontario Ministry of Finance (Estate Information Return) | The Canada Revenue Agency (the deceased's terminal T1 return) |
Why the Numbers Can Genuinely Differ
The Estate Administration Tax value only captures what actually needs a Certificate of Appointment of Estate Trustee to be transferred or accessed. Assets with a named beneficiary, and property held jointly with a right of survivorship, typically bypass probate entirely and are left out of that figure.
The deemed disposition value works differently. It generally applies to capital property the deceased owned immediately before death, regardless of how that property is structured to pass afterward. A jointly held investment account that skips probate can still produce a capital gain reportable on the deceased's share for income tax purposes — whether an asset needs probate and whether it triggers tax are simply two different questions.
Who Determines Each Number
The estate trustee is generally responsible for identifying and valuing the assets that make up the Estate Administration Tax value, and for filing the resulting Estate Information Return with the Ontario Ministry of Finance. The values used to calculate any deemed disposition gain are reported separately on the deceased's final T1 return, often prepared by an accountant, drawing on fair market valuations of the same — and sometimes different — property.
Don't Let One Filing Substitute for the Other
Because both processes ask "what was this worth when the person died," it's tempting to treat one appraisal or valuation as good enough for both purposes. In practice, an estate trustee typically needs to work through both calculations separately — and before distributing anything, should also account for the possibility that the Canada Revenue Agency wants a clearance certificate confirming no tax debts remain, quite apart from the provincial filing.
Frequently asked questions
If an asset is excluded from probate, does that mean no tax is owed on it?
Not necessarily. Being excluded from the Estate Administration Tax value only means the asset didn't need a Certificate of Appointment. It says nothing about whether that same asset triggers a taxable capital gain, or income inclusion, on the deceased's final tax return — those are assessed under a completely different set of rules.
Who actually calculates the deemed disposition value?
Typically an accountant, working alongside the estate trustee, prepares the deceased's final tax return and calculates any capital gain based on fair market value immediately before death. This is separate from — and usually happens alongside — the estate trustee's own valuation work for the Estate Information Return.
Can the same appraisal be used for both purposes?
Sometimes the same underlying appraisal, for real estate in particular, can inform both calculations. But the two filings ask different legal questions and go to different governments, so the figures ultimately reported shouldn't be assumed to match without checking.
Does the executor have to sort this out alone?
No — most estate trustees work with both a lawyer, for the probate application and Estate Information Return, and an accountant, for the terminal return and any deemed disposition calculation, since the two processes require different expertise.
