Leaving $800,000 to a Sibling in Alberta: No Spouse Rollover, Full Deemed Disposition, and the 2026 Tax Bill on a Mixed RRSP and Non-Registered Estate

The Scenario: $800,000 Alberta Estate, Single Deceased, Sibling Heir

Robert, 71, single (never married), Calgary resident. He dies in March 2026. No surviving spouse. No children. His only family: his sister Karen, 68, retired, living in Edmonton.

Robert's estate:

The question: how much of the $800,000 actually reaches Karen after CRA, Alberta surrogate court, and the executor are done?

What “Deemed Disposition” Means — and Why It Hits This Estate Twice

Canada does not have an estate tax or inheritance tax. Instead, the Income Tax Act treats the deceased as having sold all their assets at fair market value immediately before death. This is the deemed disposition under section 70(5) of the ITA. Any accrued capital gains become taxable on the deceased's final (terminal) T1 return.

For Robert's estate, deemed disposition triggers tax on two assets:

1. The RRSP ($400,000): Under section 146(8.8), the full RRSP balance is included as ordinary income on the terminal return. Not just the growth — the entire $400,000. This is the most heavily taxed Canadian asset at death.
2. The non-registered account ($300,000, with $90,000 gain): The $90,000 capital gain is realized through deemed disposition. At the 2026 inclusion rate of 50% (the gain is well under the $250,000 threshold), $45,000 is added to taxable income.

The principal residence is exempt under section 40(2)(b) — the principal residence exemption (PRE) eliminates the deemed disposition gain. One property per family unit per year qualifies.

The Terminal Return: $445,000 of Taxable Income

Robert had minimal other income in 2026 before his death in March. His terminal return is dominated by the RRSP inclusion and the capital gain:

At $445,000 of taxable income, Robert's terminal return is well into Alberta's top bracket. Alberta's top combined federal + provincial marginal rate is 48% on income above approximately $355,000.

The Alberta Tax Calculation: ~$178,000 Combined

Here is the approximate breakdown across federal and Alberta brackets:

On $445,000 of total taxable income, the combined federal + Alberta income tax is approximately $178,000. The blended effective rate across the entire terminal return is roughly 40% — but the top marginal rate on the last dollar is 48%.

Alberta Court Fees: $525 (Not a Typo)

Alberta does not charge percentage-based probate fees. The province uses flat surrogate court fees capped at $525 under the Alberta Surrogate Rules — regardless of whether the estate is $100,000 or $10 million.

Manitoba and Quebec (with a notarial will) beat Alberta on probate alone. But Alberta's combination of low income tax rates and negligible probate fees makes it one of the most tax-efficient provinces to die in.

Naming the Sibling on the RRSP vs. Leaving It to the Estate

Robert named Karen as the direct beneficiary of his RRSP. This matters for two reasons — and one common misconception:

What naming a beneficiary does NOT change

The income tax is identical. Under section 146(8.8), the $400,000 RRSP is included on Robert's terminal return whether Karen is named as beneficiary or the RRSP flows to the estate. The executor owes the same ~$178,000 either way.

What naming a beneficiary does change

• Bypasses probate: The RRSP proceeds flow directly from the custodian to Karen without going through the estate or surrogate court. In Alberta this saves little (fees are capped at $525 anyway), but in Ontario it would save $5,625 on a $400,000 RRSP.
• Creditor protection: If Robert had debts at death, the RRSP proceeds paid directly to Karen are generally protected from estate creditor claims. The non-registered account and home, which flow through the estate, are not.
• Speed: Karen receives the RRSP within weeks of providing the death certificate to the custodian. Estate assets distributed through probate can take 6–12 months.

Why Siblings Are Not “Qualified Beneficiaries”

The ITA defines who can receive an RRSP death benefit with tax deferral. The list is short:

• Surviving spouse or common-law partner: Full rollover to their own RRSP or RRIF. Tax deferred until they withdraw or die.
• Financially dependent child or grandchild under 18: “Refund of premiums” can be used to purchase a term annuity to age 18.
• Financially dependent child or grandchild with a disability: Rollover to an RDSP, RRSP, or life annuity.

That's it. Siblings, parents, adult children who are not financially dependent, nieces, nephews, friends, and charities are all excluded. For Karen, there is no mechanism to defer the RRSP income. It hits the terminal return in full.

This is the single most expensive rule in Canadian estate planning for unmarried or widowed people who leave their RRSP to anyone other than a spouse or dependent child. On a $400,000 RRSP at Alberta's rates, the tax is roughly $176,000. A spouse would defer that to zero.

The Capital Gains Inclusion Rate: Why $90,000 Is Taxed at 50%

The 2024 federal budget introduced tiered capital gains inclusion rates for individuals, effective June 25, 2024:

• 50% inclusion on the first $250,000 of annual net capital gains
• 66.67% inclusion (two-thirds) on gains above $250,000

Robert's $90,000 capital gain on the non-registered account is well below the $250,000 threshold, so the full gain is included at the lower 50% rate. The taxable capital gain: $45,000.

If the non-registered account had a larger unrealized gain — say $500,000 instead of $90,000 — the math changes significantly. The first $250,000 would be included at 50% ($125,000 taxable) and the remaining $250,000 at 66.67% ($166,675 taxable), for a total of $291,675 in taxable income from the deemed disposition alone. Combined with the $400,000 RRSP income, the terminal return would exceed $735,000 — pushing the tax bill well past $300,000.

Corporations and trusts face the 66.67% inclusion rate on all capital gains with no $250,000 threshold. If Robert had held his non-registered investments inside a holding company, the deemed disposition would trigger a higher taxable amount. For the full mechanics, see our inheritance tax Canada 2026 guide.

Net-to-Sibling Calculation: ~$621,000 of $800,000

Karen receives approximately 77% of the $800,000 estate. The other 23% goes to CRA and Alberta's surrogate court. The RRSP accounts for the vast majority of the tax: $400,000 of ordinary income at a blended rate of ~44% generates roughly $176,000 of the $178,000 total tax bill. The $90,000 capital gain on the non-registered account adds only ~$2,000 of marginal tax because it falls entirely within the 50% inclusion rate.

Executor Checklist: What Needs to Happen (and When)

1. Obtain the death certificate — required for the RRSP custodian, surrogate court, and CRA.
2. Notify the RRSP custodian — provide the death certificate and Karen's identification. The custodian issues a T4RSP to report the $400,000 as RRSP income of the deceased and pays Karen directly as named beneficiary.
3. Apply for a Grant of Probate in Alberta — required for the non-registered account and the condo. Fee: $525. File with the Alberta Court of King's Bench.
4. File the terminal T1 return — due by the later of April 30 of the following year or six months after the date of death. Include the $400,000 RRSP income and $45,000 taxable capital gain.
5. Consider a rights-or-things return — if Robert had accrued investment income (declared dividends, bond interest) at the date of death, a separate return under section 70(2) gets its own basic personal amount and can save $4,800+ in tax.
6. Request a clearance certificate from CRA under section 159 — do not distribute the estate to Karen until CRA confirms no further tax is owing. Without the certificate, the executor is personally liable.
7. Distribute the remaining assets to Karen once the clearance certificate is received and all taxes are paid.

What Could Robert Have Done Differently?

The $178,000 tax bill is large, but the options for a single person leaving everything to a sibling are limited:

• Gradual RRSP drawdown during lifetime: If Robert had withdrawn $30,000–$40,000 per year from his RRSP in his 60s (at a lower marginal rate of 30–36%) and moved the after-tax proceeds to his TFSA, he could have reduced the terminal return RRSP balance by $200,000+ and paid significantly less total tax. The RRSP meltdown strategy is the most powerful planning lever for anyone without a spouse to roll the RRSP to.
• Name a charity as partial RRSP beneficiary: A donation receipt from a charitable beneficiary designation offsets up to 100% of terminal-return income (the usual 75% net-income cap is lifted in the year of death and the preceding year under section 118.1(1)). If Robert had left $100,000 of his RRSP to a registered Canadian charity, the $100,000 donation tax credit would have reduced his terminal return tax by approximately $48,000.
• Life insurance payable to Karen: A term or permanent life insurance policy with Karen as beneficiary would have passed tax-free outside the estate, offsetting the tax bill. A $200,000 policy would have effectively restored most of the tax lost to CRA.

None of these strategies are available after death. The terminal return is the terminal return. The planning window is while you're alive — and most single Canadians with large RRSPs and no spouse don't realize their sibling will lose 20–40% of the estate to a tax bill that could have been substantially reduced.
