Testamentary Trust vs Outright Bequest in Ontario: How a $1.2M Estate Uses GRE Status to Defer $35,000 in Tax Over 36 Months

$1.2M Estate, $120,000 in Income, Two Beneficiaries — One Decision That Changes the Tax Bill by $35,000

A 74-year-old Ontario resident dies in 2026 leaving a $1.2 million estate to two adult children. The estate includes a rental property generating $18,000 per year in net rental income, a non-registered investment portfolio producing $14,000 per year in interest and dividends, and $200,000 in GICs earning approximately $8,000 per year. Combined, the estate generates roughly $40,000 per year in income.

Both children earn $80,000 or more in employment income. The executor faces a choice: distribute everything immediately — an outright bequest — and let each child report their share of the ongoing income on their personal tax returns, or retain the assets inside the estate as a Graduated Rate Estate for up to 36 months, letting the trust itself pay tax on the income at graduated rates.

Over three years, the estate will earn approximately $120,000 in total income. The tax treatment of that $120,000 differs dramatically depending on which path the executor chooses.

What Is a Graduated Rate Estate — and Why Does It Matter?

Since January 1, 2016, all trusts in Canada — including testamentary trusts — are taxed at the top combined marginal rate on every dollar of income. In Ontario, that rate is 53.53% in 2026. There is one exception: the Graduated Rate Estate.

A GRE is the estate of a deceased individual that meets four conditions under subsection 248(1) of the Income Tax Act:

• The trust arose on and as a consequence of the individual's death
• It is a testamentary trust (created by the will or intestacy)
• No more than 36 months have passed since the individual's death
• The estate designates itself as a GRE in its first T3 trust return

A GRE pays income tax at the same graduated rates as an individual. In Ontario, the first $55,867 of taxable income is taxed at a combined federal-provincial rate of approximately 20.05%. Income between $55,867 and $111,733 is taxed at approximately 29.65%. The rates continue to climb in brackets, reaching 53.53% only on income above $235,675. This progressive structure means a GRE earning $40,000 per year pays far less tax than a flat-rate trust — or a high-income beneficiary — would on the same amount.

Scenario A: Outright Bequest — Immediate Distribution

The executor distributes the entire $1.2M estate to the two children as quickly as possible. Each child receives their half: $100,000 in GICs, a 50% interest in the rental property, and half the investment portfolio. From the date of distribution onward, each child reports their share of the income on their personal T1 return.

Tax Impact on Each Beneficiary

Each child earns $80,000 in employment income. On top of that, they now receive approximately $20,000 per year in inherited investment and rental income ($40,000 total estate income ÷ 2). Their total income becomes $100,000.

At $100,000 in Ontario, the combined marginal rate on the last dollars of income is approximately 43.41% (the bracket from $98,040 to $111,733 in 2026). The blended effective rate on the $20,000 addition ranges from 37.91% to 43.41% depending on exactly where it falls in the brackets.

Using an average marginal rate of approximately 40% on the added $20,000 per beneficiary:

• Annual tax on each beneficiary's $20,000 share: ~$8,000
• Combined annual tax for both beneficiaries: ~$16,000
• Total tax over 3 years on $120,000 in estate income: ~$48,000

This is conservative. If either beneficiary earns more than $80,000, the marginal rate on the inherited income climbs further. At $110,000+ in employment income, the marginal rate on the additional $20,000 reaches 48.35% or higher, pushing the three-year total above $50,000.

Scenario B: Graduated Rate Estate — Retain Assets for 36 Months

The executor retains the estate assets — rental property, investment portfolio, GICs — inside the estate and files T3 trust returns annually, designating the estate as a GRE. The estate earns approximately $40,000 per year and pays graduated tax rates on that income.

Tax Paid by the GRE Each Year

On $40,000 of taxable income in Ontario, the GRE pays graduated rates:

• First $55,867: The entire $40,000 falls within the lowest combined bracket of approximately 20.05%
• Annual GRE tax on $40,000: ~$8,020
• Total GRE tax over 3 years on $120,000: ~$24,060

The estate can also claim deductions available to individuals — the basic personal amount ($16,129 federal for 2026) — though this is available only for the first taxation year that ends after death. In subsequent taxation years, the GRE does not get a personal amount but still benefits from graduated rates.

Three-Year Comparison

The raw tax savings from the GRE in this scenario range from approximately $27,000 to $35,000 depending on the beneficiaries' exact marginal rates. For beneficiaries earning $100,000+ each, the savings push toward the higher end. The $35,000 figure in the title assumes beneficiaries at the higher end of the range — a common scenario for adult professionals in Ontario.

The Costs That Eat Into the Savings

The GRE does not administer itself. Retaining assets in the estate for 36 months requires ongoing legal, accounting, and administrative work that an outright bequest avoids entirely.

Annual GRE Administration Costs

• T3 trust return preparation: $1,500 to $3,000 per year (depending on asset complexity — rental properties and investment portfolios require more detailed reporting than simple GICs)
• Legal compliance and trustee administration: $1,000 to $2,000 per year (executor correspondence with beneficiaries, record-keeping, CRA compliance)
• Rental property management: If the estate holds rental property, ongoing management costs continue — these exist under either scenario but may be higher with an estate as landlord rather than individual owners
• Executor compensation: Ontario allows up to 2.5% of estate value as executor compensation per year, though this is often negotiated. On a $1.2M estate, the maximum annual compensation is $30,000 — but most executors of family estates take less or nothing

When the Costs Exceed the Savings

For estates generating less than $15,000 per year in income — a $500,000 portfolio of GICs and bonds earning 3%, for example — the annual graduated rate advantage might save only $2,000 to $3,000 per year. Against $3,000 to $5,000 in annual administration costs, the GRE may not produce a net benefit. In these cases, the outright bequest is cleaner, cheaper, and gives the beneficiaries immediate access to their inheritance.

Similarly, estates with only short-duration income streams — where the income-generating assets will be liquidated within months of death — may not generate enough income during the GRE window to justify the setup and administration costs.

The 36-Month Cliff: What Happens When the GRE Expires

The GRE designation expires automatically 36 months after the date of death. There is no application for extension. There is no discretionary renewal. On the day the 36-month window closes, the estate becomes an ordinary testamentary trust taxed at the flat top combined marginal rate of 53.53% in Ontario.

What This Means in Practice

If the deceased died on March 15, 2026, the GRE status expires on March 15, 2029. Any income earned by the estate after that date — even one day after — is taxed at 53.53%. The executor must plan the wind-up timeline well in advance:

• 12 months before expiry: Begin marketing the rental property for sale, if the plan is to sell rather than distribute in-kind
• 6 months before expiry: Liquidate investments and GICs as they mature, prepare final distributions to beneficiaries
• 3 months before expiry: Complete all distributions, file the final T3 return, and apply for a clearance certificate from the CRA
• At expiry: The estate should be wound up. Any remaining assets face 53.53% taxation on income

The clearance certificate process itself can take 3 to 6 months, so prudent executors submit the request well before the 36-month deadline. The estate can still distribute assets while waiting for the certificate — the executor simply retains a reserve for any outstanding CRA assessments.

How to Draft the Will to Preserve GRE Flexibility

The most important planning step happens before death — in the will itself. A will that mandates immediate distribution removes the GRE option entirely. A will that mandates retaining assets in a testamentary trust may trap beneficiaries for years. The best approach is a flexible will that gives the executor discretion.

Key Will Provisions for GRE Flexibility

• Executor discretion clause: Grant the executor the power to retain estate assets for up to 36 months (or distribute earlier) based on tax considerations at the time of death. This preserves the GRE option without making it mandatory
• Income allocation powers: Allow the executor to allocate income to beneficiaries (making it taxable in their hands) or retain it in the estate (taxed at GRE rates), depending on which produces the better result
• Subsection 104(13.1) and (13.2) designations: The executor can use these provisions to designate income as payable to a beneficiary for tax purposes while physically retaining it in the estate. This provides flexibility to split income between the GRE and beneficiaries to optimize the overall tax bill
• Wind-up directive: Include a provision requiring the executor to distribute all remaining assets before the 36-month GRE deadline, preventing an accidental transition to flat-rate taxation

What Not to Do in the Will

Avoid language that mandates either immediate distribution ("my executor shall distribute my estate within 90 days of my death") or indefinite retention ("my executor shall hold my estate in trust for my children until they reach age 40"). Either approach eliminates flexibility. The will should be a framework that the executor can adapt to the tax environment at the time of death — not a rigid instruction written years or decades earlier.

GRE vs Outright Bequest: Sensitivity Analysis by Estate Income Level

The GRE advantage scales directly with the amount of income earned inside the estate and the beneficiaries' marginal tax rates. Here is how the three-year tax savings vary across different income levels, assuming two Ontario beneficiaries each earning $80,000+:

The breakeven point — where GRE administration costs equal the tax savings — falls at roughly $40,000 to $50,000 in total estate income over three years. Below that, the outright bequest is likely the better choice. Above that, the GRE advantage compounds quickly.

Income Types That Work Best Inside a GRE

Not all estate income benefits equally from GRE graduated rates. The type of income determines the magnitude of the advantage.

Interest Income

Interest income is fully taxable — 100% of interest earned is included in taxable income. This makes interest income the highest-value candidate for GRE retention. The difference between 20.05% (GRE lowest bracket) and 43–53% (beneficiary marginal rate) is largest on interest.

Rental Income

Net rental income (after deductible expenses like property tax, insurance, repairs, and CCA) is fully taxable. Rental properties also offer depreciation deductions that can reduce taxable income within the GRE, amplifying the graduated rate benefit. However, holding rental property in an estate creates administrative complexity — the estate becomes the landlord, responsible for tenant management, insurance, and maintenance.

Eligible Canadian Dividends

Eligible dividends benefit from the dividend tax credit, which reduces the effective tax rate. Inside a GRE at lower income levels, the dividend tax credit can actually produce a negative effective tax rate on the first tranche of dividend income. However, the gross-up mechanism (38% gross-up for eligible dividends) inflates the GRE's taxable income, which can push it into higher brackets faster. For estates with mostly dividend income, the GRE advantage is smaller than for interest-heavy estates but still meaningful.

Capital Gains

Capital gains realized inside the GRE (from selling estate assets like stocks or property) benefit from the 50% inclusion rate — only half the gain is taxable. Combined with graduated rates, a $100,000 capital gain inside a GRE could face an effective tax rate of roughly 10% on the first $55,867 of taxable capital gain, compared to 21–27% for a beneficiary at the $80,000+ income level.

Common Mistakes Executors Make with GRE Planning

1. Not Designating the GRE on the First T3 Return

The GRE designation must be made on the estate's first T3 trust return. If the executor files the first T3 without making the designation, the estate is treated as an ordinary trust from the start — no retroactive designation is possible. This is a clerical step that costs nothing but is easy to overlook, especially when an accountant unfamiliar with estate returns prepares the filing.

2. Having Multiple Estates

A deceased individual can have only one GRE. If the will creates multiple trusts (for example, a spousal trust and a residual trust), only one can be designated as the GRE. Complex wills that establish several testamentary trusts may inadvertently lose the graduated rate benefit on all but one of them.

3. Missing the 36-Month Deadline

The most expensive mistake. If the estate still holds income-producing assets past the 36-month mark, every dollar of income from that point forward is taxed at 53.53%. On $40,000 of annual income, this means approximately $21,400 in tax — compared to $8,020 under GRE rates. Executors who are slow to wind up the estate, distracted by family disputes, or waiting for real estate to sell at the right price can easily miss this deadline.

4. Distributing Too Early

Some executors distribute assets quickly to satisfy impatient beneficiaries, forfeiting years of graduated rate taxation. Once assets are distributed, the income shifts to the beneficiaries' returns at their marginal rates. The executor should explain the tax benefit of patience to beneficiaries — a $35,000 saving shared between two children is $17,500 each over three years.

Ontario Estate Administration Tax and the GRE

Ontario's estate administration tax (probate fee) of 1.5% on estate values above $50,000 is a one-time cost at death — it does not change based on whether the executor chooses the GRE or outright bequest route. On a $1.2M estate, the probate fee is approximately $17,250 regardless. The GRE decision affects only the ongoing income tax treatment, not the probate fee.

However, one interaction matters: assets that pass outside the estate — jointly held property, insurance proceeds, registered accounts with named beneficiaries — are not subject to probate and are not available for the GRE to earn income on. Estates that have been minimized through probate-avoidance strategies may not have enough income-producing assets remaining inside the estate to make the GRE worthwhile. The probate-avoidance strategy may conflict with the GRE income-splitting opportunity.

The Bottom Line: When to Use a GRE and When to Distribute

For a $1.2M Ontario estate generating $40,000 per year in income with beneficiaries earning $80,000+, the GRE saves approximately $27,000 to $35,000 in tax over 36 months. After $9,000 to $18,000 in administration costs, the net benefit is $9,000 to $26,000 — meaningful money that justifies the complexity.

Use the GRE when: the estate holds income-producing assets (rental property, interest-bearing investments, dividend portfolios), the beneficiaries have high personal marginal rates ($80,000+ income), and the total estate income over 36 months exceeds $50,000.

Skip the GRE when: the estate consists primarily of a principal residence and registered accounts (which pass outside the estate), the total estate income will be less than $40,000 over 36 months, or the beneficiaries have low marginal rates that are close to the GRE graduated rates anyway.

Most importantly, build the flexibility into the will now. An inheritance financial planner can draft GRE-ready will provisions, model the tax savings for your specific asset mix and beneficiary income levels, and plan the 36-month wind-up timeline to capture the full benefit without risking the cliff. On a $1.2M estate, the cost of this planning — typically $2,000 to $5,000 — is a fraction of the $35,000 in tax it can save.
