Key takeaways
  • On death, each capital property is deemed sold immediately before death at fair market value, even if it is never sold.
  • The taxable capital gain or loss is calculated on Schedule 3 and reported on line 12700 of the final return.
  • Rollovers, the principal residence exemption and other relief can reduce or defer the tax, but each has conditions.

If you are the executor, one of the most surprising parts of a final return is that the deceased is treated as having sold their capital property on the day they died. The tax can arise even when the house, shares or land stay in the family.

This article explains the rule, where the gain is reported, and the main ways the tax can be reduced or deferred. It is general information, and complex estates are worth reviewing with an accountant or lawyer.

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

What deemed disposition means

Under section 70(5) of the Income Tax Act, each capital property is deemed sold immediately before death at fair market value. The person who acquires the property is deemed to acquire it at that value.

In plain words, the tax system treats death as a sale for tax purposes. You do not need to sell anything for the gain or loss to be counted.

Where it goes on the final return

The taxable capital gain or loss is calculated on Schedule 3 and reported on line 12700 of the final return. Income earned up to the date of death also goes on the final return, even if it is received after death, unless it is put on an optional return.

Income the estate earns after death, such as investment, business, farming and rental income, is reported on the T3 return and not on the final T1.

Ways the tax can be reduced or deferred

Several rules can change the result. They have conditions, so check each one against the facts of the estate.

SituationHow it works
Property to a surviving spouse or common-law partnerProperty can roll over without a gain or loss if the survivor was a Canadian resident and it vests in them within 36 months of death. The legal representative can elect out, property by property.
Principal residenceThe gain may be exempt only if designated on Schedule 3 and Form T1255 in the final return. This is not needed if the property is rolled to a spouse.
Farm, fishing or small business propertyQualified farm or fishing property and qualified small business corporation shares may qualify for the lifetime capital gains deduction.
Capital lossesNet capital losses of the final and prior year can offset other income. Losses on personal-use property cannot be claimed, except on listed personal property.

Common points of confusion

A frequent question is whether the estate must sell the property to pay the tax. The deemed sale happens for tax purposes whether or not there is an actual sale. Whether the estate has cash to pay the tax is a practical matter to discuss with a lawyer or accountant.

Another is the due date. For a death between January 1 and October 31, the final return and any balance owing are both due April 30 of the year following the death. For a death between November 1 and December 31, the final return is due 6 months after the date of death. Payment dates do not move with the later filing dates, and you may need to pay before filing to avoid interest.

Late filing with a balance owing can bring a penalty of 5% of the balance plus 1% of the balance for each full month late, up to 12 months. Interest is compounded daily on unpaid amounts.

What to do next

Valuations, elections and the choice between filing options can change the tax result. An accountant or lawyer can confirm the figures before you file.

Frequently asked questions

Do we have to sell the property to trigger the gain?

No. The gain or loss is calculated and reported on the final return even if the property is not sold.

Which form is used to report the gain?

Schedule 3 is used to calculate the taxable capital gain or loss, which is reported on line 12700 of the final return.

Can the gain on the family home be exempt?

It may be, if the principal residence is designated on Schedule 3 and Form T1255 in the final return. Designation is not needed if the property is rolled to a spouse.

Can capital losses be used on the final return?

Net capital losses of the final and prior year can offset other income. Capital losses on personal-use property cannot be claimed except on listed personal property.
