When someone dies, their personal tax obligations do not simply end, and neither do their estate's. Once an estate starts earning income of its own (interest on an investment account, rental income from a property still being administered, dividends from shares not yet distributed), that income generally has to be reported separately from the deceased's own final return. The form that does this is the T3 Trust Income Tax and Information Return, and understanding it is one of the less obvious responsibilities that falls on an executor or trustee.
T1 vs. T3: Two Different Returns, Two Different Taxpayers
It helps to separate two things that get confused constantly:
- The deceased's final T1 return reports the person's own income up to the date of death, plus certain deemed dispositions triggered by death itself. This is filed once, for the individual.
- The estate's T3 return reports income the estate earns after death, as its own separate taxpayer, for as long as the estate continues to hold assets and generate income during administration.
An estate trustee is often responsible for both, but they are legally distinct filings covering different periods and different taxpayers.
Who Has to File a T3
Any trust, including a deceased person's estate acting as a trust during administration, that earns income generally has a T3 filing obligation. This applies whether the trust is:
- An estate being wound up by an executor or estate trustee, or
- An ongoing trust set up during someone's lifetime or created under a will (a testamentary trust) that continues after the estate is settled.
The trustee, not the beneficiaries, is responsible for filing the T3 on behalf of the trust, even though income allocated out to beneficiaries is often taxed in their hands rather than the trust's.
The Graduated Rate Estate: Why Timing Matters
Not every estate is taxed the same way. A deceased person's estate can generally access graduated tax rates, the same kind of stepped-rate structure an individual gets, but only during a limited initial period after death, under what is called the graduated rate estate (GRE) regime.
Once that window closes, the estate (if it continues to exist) is generally taxed at the top marginal rate, with no basic personal exemption, the same treatment that applies to most other trusts. This is a significant shift, and it is one reason the timing of an estate's administration, and its fiscal year-end choices, matter for tax planning during that period.
What the T3 Return Reports
A T3 return covers the trust's or estate's own income for its tax year, along with information about amounts allocated to beneficiaries. Broadly, this includes:
- [ ] Interest, dividend, and investment income earned by estate or trust assets
- [ ] Rental income from estate-held property
- [ ] Capital gains realized on the sale of estate assets during administration
- [ ] Income allocated (and taxed) to beneficiaries versus income retained (and taxed) in the trust itself
Because the T3 has its own filing deadline, separate from the T1 filing deadline, executors need to track both on their own timelines rather than assuming one due date covers everything. Confirm the current deadline for your specific trust year before you file.
Executor Risk: Distributing Before Tax Is Settled
One of the more serious risks for an estate trustee is distributing estate assets to beneficiaries before the estate's tax position is finalized. An estate trustee who distributes before obtaining a CRA Clearance Certificate risks becoming personally liable for any unpaid taxes of the deceased or the estate, including tax that turns up later on a T3 the trustee already filed, if CRA subsequently reassesses it. Filing accurate, complete T3 returns is part of protecting yourself from that exposure.
Frequently asked questions
Does every estate need to file a T3, even a small one?
If the estate earns any income during administration, even modest interest on an account, a T3 filing obligation generally applies. Whether a specific estate's income is significant enough to matter in practice is worth confirming with an accountant, but the obligation is not limited to large estates.
What happens to income if the estate distributes assets to beneficiaries during the year?
Income allocated to beneficiaries during the trust's tax year is generally taxed in the beneficiaries' hands rather than the trust's, and reported to them on a T3 slip. Income the trust retains is taxed in the trust itself.
Do jointly held assets or assets with a named beneficiary need to be reported on the estate's T3?
Assets that pass outside the estate, such as jointly held property with right of survivorship or assets with a named beneficiary like an RRSP or life insurance policy, typically are not part of the estate and would not generate income reported on the estate's own T3.
Can an executor file the T3 themselves, or do they need an accountant?
There is no legal requirement to hire an accountant, but T3 returns involve technical concepts, including the GRE regime, income allocation, and capital gains on estate assets, that make professional preparation worthwhile for anything beyond the simplest estate.
