Graduated Rate Estate (GRE) and Final T1 Canada 2026 — Estate Tax Filing Guide for Executors

Reviewed by Bader A. Chowdry, CPA, CA, LPA on June 17, 2026

When a Canadian dies, the person named as executor (or estate trustee) inherits a tax problem most people have never seen before — and a personal financial risk most never realize they are carrying. This is the 2026 guide to the final T1 return, the Graduated Rate Estate (GRE) designation, and the clearance certificate that protects you from personal liability.

What tax returns must an executor file when someone dies in Canada?

Two separate taxpayers arise on death. The executor files a final T1 personal return for the deceased — covering January 1 to the date of death — and a T3 trust return for income the estate earns afterward. If the estate qualifies as a Graduated Rate Estate, the T3 is filed at graduated rates for up to 36 months. Optional separate returns can split income across additional returns and duplicate personal credits.

How does a Graduated Rate Estate (GRE) reduce tax in 2026?

A GRE is the deceased’s testamentary estate, designated as a GRE on the first T3 return. For up to 36 months after death it pays tax at graduated personal rates instead of the flat top rate — 53.53% in Ontario — saving tens of thousands on investment income earned during administration. It also preserves access to the principal residence exemption and lets the estate allocate certain losses and credits to beneficiaries.

What happens to RRSPs and RRIFs when someone dies?

The entire fair market value of every RRSP and RRIF is deemed received as income on the final T1 in the year of death — usually the single largest item. A tax-free rollover is available only if the account passes to a surviving spouse, common-law partner, or a financially dependent child or grandchild. With no eligible beneficiary, the full balance is taxed at up to 53.53% in Ontario.

The Two Tax Obligations on Death

When a Canadian resident dies, two separate tax obligations arise simultaneously, and they belong to two different taxpayers:

• The Final T1 Return — a personal income tax return for the deceased individual covering January 1 of the year of death to the date of death, filed by the executor or administrator.
• The Trust T3 Return — a trust income tax return for the estate itself, covering income earned by the estate’s assets after the date of death until the estate is fully wound up. If the estate is a GRE, the T3 is filed annually until the GRE period ends.

The Final T1 Return — Obligations and Income

The final T1 must include all income the deceased earned from January 1 to the date of death:

• Employment, business, and professional income up to the date of death.
• Pension income, CPP, OAS, and RRSP annuity income up to the date of death.
• RRSP/RRIF deemed receipt — the full fair market value of all RRSP/RRIF accounts is included in the deceased’s income in the year of death unless a qualifying rollover to a surviving spouse or common-law partner is made.
• Deemed disposition capital gains — capital property is deemed disposed of at fair market value on the date of death, with the usual exclusions.
• Investment income accrued to the date of death.

The final T1 is generally due by April 30 of the year following death — or June 15 if the deceased had self-employment income — but the CRA allows extended deadlines where death occurs late in the year. Always confirm against the CRA’s published filing and payment due dates for a deceased person.

Optional Returns — A Tax-Reduction Strategy

The Income Tax Act permits optional separate returns for certain income that accrued before death, splitting income across multiple returns and reducing overall tax through bracket and credit duplication:

• Return for rights or things — ITA s.70(2): income that existed as a right at death but had not yet been received — unpaid salary owed at the date of death, a farmer’s crop inventory, or a cash-basis professional’s accounts receivable. It can be reported on a separate return with its own full set of personal credits. See the Income Tax Act, section 70 on the Justice Laws website.
• Return for income from a testamentary trust in the year of death, where applicable.

Used correctly, optional returns can save thousands by preventing income from stacking on top of the final T1 and triggering the highest marginal rates.

RRSP/RRIF on Death — The Biggest Single Item

For most Canadians, the deemed collapse of the RRSP or RRIF is the largest income item on the final T1. The entire fair market value is included in income unless one of these rollovers applies:

• Spousal rollover: if the RRSP/RRIF passes to a surviving spouse or common-law partner as a designated beneficiary, the proceeds roll over tax-free into that person’s RRSP (or RRIF if they are over 71). No tax is triggered on the deceased’s final T1 for that amount.
• Financially dependent child or grandchild rollover: a financially dependent child or grandchild can roll proceeds into their own RRSP, an annuity, or an RDSP (if disabled), deferring the tax.
• No eligible rollover: the full RRSP/RRIF value hits the final T1 at the deceased’s marginal rate — in Ontario, up to 53.53% on the top dollar.

What Is a Graduated Rate Estate (GRE)?

A Graduated Rate Estate is a testamentary trust — the deceased person’s estate — that meets specific criteria allowing it to pay tax at graduated personal income tax rates instead of the highest marginal rate that otherwise applies to trusts. The definition lives in subsection 248(1) of the Income Tax Act.

GRE advantages:

• Tax at graduated rates instead of the flat top rate (53.53% in Ontario) — meaningful savings on investment income earned while the estate is administered.
• Access to the Principal Residence Exemption on a qualifying residence held in the estate.
• The ability to allocate certain losses and credits to beneficiaries, and to apply a capital loss carryback under ITA s.164(6).

GRE eligibility requirements:

1. It must be a testamentary trust arising on the death of a specific individual.
2. It must be designated as a GRE in the first T3 return filed for the estate.
3. It can remain a GRE for a maximum of 36 months after the date of death.
4. There can be only one GRE per deceased individual.

Important: the GRE designation must be made on the first T3 filing. Miss it and the estate pays tax at the flat top rate on all trust income from day one. The CRA explains the GRE’s deemed year-end and 36-month cessation in its guidance on the trust tax year-end and fiscal period.

GRE vs Ordinary Estate Trust — The Tax Difference

An estate that qualifies as a GRE in Ontario saves approximately the following on investment income earned during administration:

Estate investment income	GRE tax (graduated)	Ordinary trust tax	Annual saving
$50,000	~$10,800	~$26,765	~$15,965
$100,000	~$26,765	~$53,530	~$26,765
$200,000	~$64,890	~$107,060	~$42,170

These savings accumulate over up to three years of GRE administration. For closely held businesses, related structures such as an estate freeze under Section 86 and the 21-year deemed disposition rule for trusts often interact with estate administration and should be planned together.

The T3 Estate Trust Return

During the GRE period the executor files an annual T3 trust return. The estate can choose any fiscal year-end that is not more than 12 months after the date of death. Choosing a non-calendar fiscal year can defer income and manage tax timing. Income allocated to beneficiaries in the year it is distributed is taxed in their hands, potentially at a lower rate; retaining income in the GRE preserves the graduated rates. The T3 and any balance are due within 90 days of the trust’s tax year-end.

Executor Liability — The Clearance Certificate

An executor who distributes estate assets to beneficiaries before obtaining a CRA clearance certificate (Form TX19) is personally liable for any tax the estate later owes. The process:

1. All final T1 returns and optional returns are filed and assessed.
2. All GRE T3 returns up to wind-up are filed and assessed.
3. Request clearance using Form TX19, listing all assets distributed or to be distributed.
4. Wait for CRA clearance — typically 60 to 120 days, longer for complex estates.
5. Distribute only after clearance is received.

If the estate owes $50,000 in tax and the executor has already distributed everything, the executor is personally on the hook for that $50,000. Review the CRA’s instructions to apply for a clearance certificate and the TX19 form itself before distributing anything.

Ontario adds a separate cost: the Estate Administration Tax (probate). Since January 1, 2020 the first $50,000 of estate value is exempt, and the tax is $15 per $1,000 of value above $50,000 with no upper cap — roughly $29,250 on a $2 million estate.

Case Study — Mississauga Business Owner’s Estate Saves $86,000 via GRE + Optional Returns

Composite illustration; client details anonymized.

A Mississauga manufacturing company owner died in November 2025 with an RRSP balance of $620,000 (no surviving spouse; adult children), a non-registered portfolio of $480,000 (ACB $120,000; gain $360,000), accrued corporate salary of $95,000 unpaid at death, and projected estate income of $55,000/year in interest for about 2.5 years.

Without planning, the final T1 would have included the $620,000 RRSP income, a $180,000 taxable capital gain, and the $95,000 accrued salary — roughly $895,000 of taxable income, taxed almost entirely at Ontario’s top rate of 53.53%, for tax of approximately $479,000.

With planning by Bader A. Chowdry, CPA, CA, LPA:

1. The $95,000 accrued salary was filed on a separate “rights or things” return under ITA s.70(2), with its own credits and brackets — saving about $22,000.
2. The estate was designated a GRE on the first T3 filing; the $55,000/year of administration income was taxed at graduated rates, saving about $17,000/year for 2.5 years — roughly $42,500.
3. One adult child was financially dependent (in full-time school); $85,000 of RRSP proceeds was rolled into a term annuity in the child’s name, deferring that amount out of the final T1.

Total tax saving: approximately $86,000. The executor obtained the clearance certificate before distributing — and carried no personal exposure.

Frequently Asked Questions

Q: How long does an executor have to file the final T1 return?
A: The final T1 is due by April 30 of the year following death (or June 15 if the deceased had self-employment income). If death occurs between November 1 and December 31, the executor gets 6 months from the date of death if that is later than April 30.

Q: Can a deceased person’s TFSA be transferred to a spouse tax-free?
A: Yes. A TFSA can pass to a surviving spouse’s TFSA as an “exempt contribution” — without using their own TFSA room — if done within the rollover period (generally 36 months after death). Income earned after death is taxable if left in the estate rather than transferred.

Q: Does the estate pay probate fees in Ontario?
A: Yes. The Estate Administration Tax applies to estates that must be probated. Since 2020 the first $50,000 is exempt, then $15 per $1,000 above $50,000, with no cap. On a $2 million estate, probate is approximately $29,250.

Q: What happens to capital losses the deceased did not use?
A: Net capital losses from the year of death can be claimed against any income on the final T1 — not just capital gains. Unused net capital losses from prior years can also be claimed in the year of death against any income, subject to an inclusion-rate adjustment.

Q: Can the estate hold a principal residence?
A: Yes. A GRE can claim the Principal Residence Exemption for a property that was the deceased’s principal residence, generally for up to one year after death while the estate continues to own it. This is one reason to administer the estate promptly.

Q: How do I get a CRA clearance certificate?
A: File Form TX19, listing all assets distributed or to be distributed. The CRA assesses outstanding taxes, confirms a nil balance, and issues the certificate — usually in 60 to 120 days. Do not distribute assets before receiving it.
