Does the Estate Pay Tax on a Gain After Death in Canada?

Learn how Canada taxes a gain on property an estate sells after death, which return reports it, and how the date-of-death value sets the cost base.

Key takeaways
  • The deceased reports the gain up to the date of death on the final return, while income and gains after death go on the estate's T3 return.
  • Heirs take inherited property at its fair market value at death, which sets their adjusted cost base.
  • A spouse rollover, farm or fishing property rules and the principal residence exemption can change the result.

You are the executor and the house, shares or cottage is about to be sold. The price may be higher than it was on the date of death, and you want to know who pays tax on what, and on which return.

The short answer is that Canada taxes two different periods separately. Gains up to the moment of death belong on the final return, and growth after death belongs to the estate. Knowing the split helps you avoid reporting the same gain twice.

This article covers Canadian federal tax law, which applies in every province.

Two periods, two returns

On death, a person is deemed to have disposed of each capital property immediately before death for proceeds equal to its fair market value. The final return carries this tax, not an inheritance tax. The gain or loss is the fair market value on the date of death minus the adjusted cost base, reported on Schedule 3 and line 12700 of the final return.

The deceased reports that gain on the final return, not the beneficiaries. After death, income the estate earns and gains on property the estate sells are reported on the estate's T3 Trust Income Tax and Information Return, with capital gains on T3 line 1 using T3 Schedule 1.

A simple way to see the split

PeriodWhat is taxedWhere it is reported
Up to deathDeemed gain: fair market value at death minus adjusted cost baseFinal return, Schedule 3 and line 12700
After deathGrowth between death and the estate's saleEstate's T3 return, line 1 and Schedule 1
Later sale by an heirSale price minus the value reported on the final returnDepends on your situation, so confirm with a lawyer or accountant

So the gain up to death is reported on the final return, and gains on property the estate sells after death are reported on the estate's T3 return. How the estate's own gain is worked out on a particular sale depends on the facts, so it is worth confirming with a lawyer or accountant.

Why the date-of-death value matters

A person who acquires property because of the death is deemed to acquire it at a cost equal to its fair market value immediately before death. That sets the heir's adjusted cost base. A beneficiary who later sells generally calculates gain or loss as the sale price minus the value reported on the final return. Current expenses such as maintenance and repairs cannot be added to the adjusted cost base.

The CRA describes fair market value as usually the highest dollar value you can get for property in an open and unrestricted market, and it tells owners to keep records of the value on the date they inherit. How much evidence supports a value, such as an appraisal for a house or private company shares, depends on the property. Ask a lawyer or accountant what is sensible for your estate.

Exceptions that change the result

What to do next

Because the pre-death and post-death calculations interact, speak with a lawyer or accountant before listing a high-value property.

Frequently asked questions

Do the beneficiaries pay tax on the deemed gain at death?

No. The gain is reported by the deceased on the final return, not by the beneficiaries. A beneficiary only reports a gain later if they sell and the price is above the value reported on the final return.

Where do I report a gain when the estate sells after death?

Gains on property the estate sells after death go on the estate's T3 return, with capital gains on line 1 using Schedule 1. They are not added to the final return.

Can the estate's loss ever be used on the final return?

Sometimes. If a graduated rate estate disposes of capital property in one of its first three taxation years and its capital losses exceed gains, the legal representative may elect to treat part of the excess as the deceased's loss. The election is made by the estate's filing due date for that year, and the final return must be amended.

Is the principal residence gain automatically tax-free?

Not automatically. A gain is fully exempt if the home was the principal residence for all years owned, or all but one, and no other property was designated for those years. It must still be reported and designated.
