Here is a quirk of Canadian tax that surprises almost every family: when a parent dies, their home is effectively sold twice. Once on paper, on the date of death, and once for real, when the estate lists it. Each sale has its own tax return, and the second one can carry real tax.
Key takeaways
- The capital gains inclusion rate is 50 per cent for 2025 and 2026. A proposed increase to two-thirds was cancelled and never took effect, so a taxable capital gain is half of the gain.
- On the date of death, subsection 70(5) deems the deceased to have sold their home at fair market value. The principal residence exemption usually erases the tax, but you must still report the disposition on the final return.
- The designation form for a deceased person is Form T1255, not the T2091 a living owner uses. Missing it can cost $100 for each complete month it is late, up to a maximum of $8,000.
- When the estate later sells the home, the gain is the sale price minus the date-of-death value minus selling costs. The principal residence exemption is generally not available to the estate, so that second sale can be taxable.
- If the home passes to a surviving spouse or common-law partner, a spousal rollover under subsection 70(6) usually defers the tax until that spouse later sells or dies.
What a deemed disposition on death actually means in Canada
When a Canadian passes away, there is no inheritance tax or estate tax in Canada. Instead, the Canada Revenue Agency uses a deemed disposition on death. Under subsection 70(5) of the Income Tax Act, a person who dies is deemed to have disposed of all of their capital property, at fair market value, immediately before death. Nobody actually sells anything on that day. The CRA simply treats the disposition as if it happened so it can measure the gain that built up during the person's lifetime. This is the tax that lands upon death.
This deemed disposition of assets covers all of the deceased's capital property, not only the house. Capital property owned at death includes most of a person's assets: real estate, investments, personal-use property like a cottage, and depreciable property such as a rental building. Each type of property is valued at the time of death. For most families the family home is the big one, so that is what this article follows, and the home has a powerful shield the other assets do not. The lifetime capital gains exemption, which shelters gains on qualified farm or fishing property and small business shares, does not cover a family home.
Sale one: the deemed disposition on the final return
The first sale happens on the deceased's final tax return, also called the terminal T1. The date of death is the date of disposition for that first sale. The legal representative reports the deemed disposition of the home on Schedule 3, using the date-of-death value as the proceeds of disposition and the home's original cost as the cost base. That normally produces a gain on the property.
For a home that was the person's principal residence, the principal residence exemption usually wipes that gain out for the years it was their main home. So sale one often creates no tax at all. That is the part families rely on, and it usually works.
Here is the trap. Even when the gain is fully exempt, you still have to report the disposition and designate the property. For someone who has died, the legal representative files Form T1255, the designation for a deceased individual. A living owner uses Form T2091 instead, so do not grab the wrong one. Skip the paperwork and the CRA can apply a late-designation penalty: $100 for each complete month the designation is late, up to a maximum of $8,000. You forgot one form, and it costs you. The CRA describes this relief and penalty in its taxpayer relief guidance, IC07-1.
The final return is due by April 30 of the year following the death when the death happened between January 1 and October 31. You can read the CRA rules on the deceased capital gains page.
How to prove the value at the date of death
Because the date-of-death value becomes the estate's cost for the second sale, this number matters a lot, and you want it defensible. There are two common ways to set it.
The first is a realtor's opinion of value, a short letter based on comparable sales. It is often free, and it is fine for a straightforward estate. The second is a formal appraisal from a designated appraiser, which typically runs in the range of $300 to $500. An appraisal costs money, but it is far more robust if the CRA ever questions the value years later. As a rule, the appraisal is the better paper trail. Whichever route you take, keep the document with the estate records. It also does double duty in Ontario, since the same date-of-death value supports the estate's probate figure.
Sale two: when the estate sells the home
Months usually pass before the home is cleared out, listed and sold. By then the seller is not the deceased. It is the estate, which the CRA treats as a separate taxpayer, a testamentary trust. So the real sale is reported on the estate's T3 Trust Income Tax and Information Return, not on the deceased's personal return.
The estate's capital gain is the actual sale price, minus the cost base, minus the selling costs like the real estate commission and legal fees. And here is the key difference: the estate's cost base, technically its adjusted cost base, is the date-of-death fair market value, not what the parent paid decades ago. The estate is considered to have acquired the home at that value, and a beneficiary who inherits the home instead of cash is deemed to have acquired it at the same fair market value of the property. The principal residence exemption is generally not available to the estate, because a trust cannot ordinarily inhabit a home. A narrow exception exists when a qualifying beneficiary, such as a surviving spouse, lives there during the administration.
So the second sale, the real sale of the property, is where a taxable capital gain can appear. If the home rises in value between the date of death and the actual sale, half of that increase, less costs, is a taxable capital gain added to the estate's income for the year.
| Feature | Sale one: deemed disposition at death | Sale two: the estate's actual sale |
|---|---|---|
| When it happens | On the date of death | When the estate lists and sells, often months later |
| Whose return | The deceased's final T1, on Schedule 3 | The estate's T3 trust return |
| Proceeds | Fair market value on the date of death | The real sale price |
| Cost base | The home's original cost | The date-of-death fair market value |
| Principal residence exemption | Usually available, so often no tax | Generally not available to the estate |
| Form to remember | Form T1255 | The T3 return |
A Durham Region example: an Oshawa bungalow sold twice
Say a parent in Oshawa owns a bungalow worth $800,000 on the date of death, and the home passes to two adult children, not a spouse. On the final return, the deemed disposition happens at that $800,000 value. The principal residence exemption covers the lifetime gain, so there is no tax, but the estate still files Schedule 3 and Form T1255. The estate's cost base is now $800,000.
Ten months later the estate sells for $840,000. After about $42,000 in commission and legal fees, net proceeds are roughly $798,000. The estate's gain is $798,000 minus the $800,000 cost base, which is a $2,000 capital loss. No tax, and a graduated rate estate can even carry that small loss back against the final return.
Now change one thing. Suppose the value at death had been set too low, at $760,000, to save a little effort. The sale is still $798,000 net, but the cost base is now only $760,000. That manufactures a $38,000 capital gain. Half of it, a $19,000 taxable capital gain, gets added to the estate's income and taxed at the estate's marginal rate. The same house, the same sale, and a careless valuation created a real tax bill out of thin air. Valuing the home accurately and defensibly at death is one of the simplest ways to protect the family.
The surviving spouse changes everything
The two-sales problem mainly hits an estate with no surviving spouse, such as a parent's home passing to adult children. If the home instead passes to a surviving spouse or common-law partner, a spousal rollover under subsection 70(6) generally applies. On this transfer of property to a spouse, the property transferred to a surviving spouse moves at its cost base rather than at fair market value, so there is no deemed gain on the first death. The tax is deferred until the spouse later sells the home or dies. This is why the sold-twice squeeze is really a second-death or no-spouse issue, and why estate planning for a couple looks different from planning for a single owner.
Renting a parent's home after a move: the subsection 45(2) election
Here is a planning move most families have never heard of. Say aging parents move into a retirement residence but are not ready to sell the house, so they rent it out. Turning a home into a rental is a change in use, and the CRA normally treats a change in use as a deemed disposition at fair market value under paragraph 45(1)(a), triggering income tax on the accrued gain. From that point the home is an investment property and future growth is taxable.
Filing a subsection 45(2) election lets you treat the property as though no change in use happened. You can keep designating it as your principal residence for up to four more years while it is rented, which defers the deemed disposition. The conditions matter: you cannot claim capital cost allowance, or depreciation, on the property while the election is in force, since claiming even a dollar of it voids the election. The owner must be a resident of Canada, no other property can be designated as the principal residence for those years, and the rental income still has to be reported on Form T776. The election is not a checkbox. You attach a signed letter to the T1 income tax return for the year of the change in use, stating that you elect under subsection 45(2). If you missed it, the CRA may still accept a late election at its discretion, but only if no capital cost allowance was ever claimed. The details live in Guide T4037 and Income Tax Folio S1-F3-C2.
How to reduce the tax legally
You cannot avoid the deemed disposition itself, but you can shrink or defer what it costs and lower the family's overall tax burden. A few levers do most of the work, and each rewards planning before the sale rather than after.
- Use the principal residence exemption on the first sale, and file the T1255 designation so you keep it.
- Value the home accurately at death, so the estate's cost base is as high as it honestly should be.
- Sell the property within about three years. An estate can be a graduated rate estate for up to 36 months, which lets it use graduated tax rates instead of the top flat rate.
- Use the loss carryback when the sale nets less than the date-of-death value. A graduated rate estate can elect under subsection 164(6) to carry that capital loss back against the deceased's final return. Legislative amendments extended the window: for deaths on or after August 12, 2024, the loss can be applied within the estate's first three taxation years rather than only its first year.
None of these is aggressive. They are the ordinary tax planning a CPA runs through with an executor, and together they can cut the tax on capital gains from an inherited house by thousands of dollars. If you are settling a parent's estate around Durham Region, an accountant in Oshawa or Whitby who does estate work can map the two sales before you list the home.
Losing a parent is hard enough without a surprise tax bill on the family home. The good news is that the two sales are predictable, and the tax on the second one is usually manageable when you plan the valuation, the timing and the paperwork in advance.
