Key takeaways
  • A graduated rate estate that disposes of capital property in one of its first three taxation years and has capital losses above gains may elect to treat part of the excess as the deceased's loss.
  • The election must be made by the estate's filing due date for that year, and the final return must be amended.
  • Gains on property the estate sells after death are reported on the estate's T3 return, not the final return, though a graduated rate estate may elect to treat part of an excess capital loss as the deceased's loss.

Markets move after a death. If the estate sells investments for less than they were worth on the date of death, you may be left with a loss in the estate and a tax bill already assessed on the final return. It is natural to ask whether that loss can be sent back.

This article explains how the graduated rate estate election works, who can use it, and the practical steps and deadlines. Whether the estate qualifies and how much to claim should be confirmed with an accountant or lawyer.

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

Why the estate loss does not automatically go back

On death, the deceased is treated as having disposed of each capital property immediately before death at fair market value, and the resulting gain is reported on the final return. The person who inherits is treated as acquiring the property at that same value.

If the estate then sells the property for less, the loss is a post-death event. Gains on property the estate sells after death are reported on the estate's T3 return, using T3 Schedule 1, not on the final return. A graduated rate estate may, however, elect to treat part of an excess capital loss as the deceased's loss on the final return.

The election for graduated rate estates

If a graduated rate estate disposes of capital property in one of its first three taxation years and its capital losses exceed its gains, the legal representative may elect to treat part of the excess as the deceased's loss on the final return.

Whether a particular estate is a graduated rate estate depends on its circumstances, so it is worth confirming with a lawyer or accountant before you rely on it.

How this fits with losses already on the final return

In the year of death, net capital losses on the final return and the prior year's return can offset income other than capital gains, which is not normally allowed in other years. Net capital losses of other years are claimed on line 25300 of the final return. A related rule lets unused net capital losses for all taxation years that are not otherwise claimed be deducted in computing taxable income in the year of death.

Where the loss arisesWhere it is reported
Deemed disposition at deathFinal return, Schedule 3
Sale by the estate after deathEstate T3 return, Schedule 1
Estate loss moved back by electionFinal return, which must be amended

If the final return was already filed and assessed, the amendment is how the benefit is claimed. The election does not remove the need for the final return to reflect the original deemed disposition.

Timing, penalties and distributions

The T3 return is due 90 days after the trust's year-end. Because the election is tied to the estate's filing due date for the year of the loss, missing that date can cost you the option. A late T3 return can also attract a penalty of $25 per day, with a minimum of $100 and a maximum of $2,500, even where no balance is owing.

A legal representative must obtain a clearance certificate before distributing property, or be personally liable for unpaid amounts to the extent of the value of property distributed. A new certificate is not required before each distribution as long as enough property is kept to cover any potential liability. Because an amended final return can change the amounts owing, it is wise to discuss timing with your advisor before distributing everything.

What to do next

Because the rule only reaches the first three taxation years, sales planned late in that period deserve extra attention. Talk to your advisor before selling, not after.

Frequently asked questions

Can an estate carry a capital loss back to the final return?

Yes, in a limited case. A graduated rate estate that disposes of capital property in one of its first three taxation years, and whose capital losses exceed its gains, may elect to treat part of the excess as the deceased's loss.

What is the deadline for the election?

The election must be made by the estate's filing due date for the year of the loss. The T3 return itself is due 90 days after the trust's year-end.

Do I need to amend the final return?

Yes. The final return must be amended for the election to take effect.

Can I move the whole loss back?

The rule allows the representative to treat part of the excess of capital losses over gains as the deceased's loss. How much to claim is something your accountant can work out.
