Trust 21-Year Deemed Disposition Canada 2026 — Planning, Budget 2025 Update

Quick Answer

The Trust 21-year deemed disposition Canada 2026 rule in one paragraph: paragraph 104(4)(b) of the Income Tax Act deems every personal trust (including discretionary family trusts, alter ego trusts, joint partner trusts, and most spousal trusts) to dispose of each of its capital properties (other than depreciable property used in active business) at fair market value on its 21st anniversary — and to immediately re-acquire those properties at the same value. The trust pays tax on the accrued capital gains at the trust’s top marginal rate (53.53% combined federal-Ontario in 2026, applied to 50% of the gain — effective 26.77%). For a discretionary family trust holding $5 million of QSBC shares with $4.8 million of accrued gain, the unmitigated deemed-disposition tax is approximately $1.28 million. Three mitigation pathways exist: distribute the underlying property to capital beneficiaries on a tax-deferred basis under subsection 107(2) before the 21-year anniversary (most common — basis rolls to the beneficiary at the trust’s adjusted cost base); execute a butterfly reorganization to split the trust’s holdings among related corporations of beneficiaries; or accept the deemed disposition and use the trust’s LCGE multiplication (each capital beneficiary’s LCGE) by realizing the gain ahead of the deemed disposition. Budget 2025 introduced rules that capture indirect trust-to-trust transfers within the 21-year regime, closing what was a common planning loophole — moving property to a new trust via a corporate intermediary owned by the new trust is now subject to the 21-year rule on a look-through basis. Planning typically begins 3–5 years before the anniversary; starting in year 19 or 20 limits the structural options.

What the 21-year rule does

Paragraph 104(4)(b) of the Income Tax Act says a trust is deemed to have:

• Disposed of each of its capital properties (other than depreciable property used in an active business) at the fair market value on the 21st anniversary of the trust’s creation, and
• Immediately re-acquired those properties at the same fair market value.

The deemed disposition triggers a capital gain (or loss) inside the trust equal to FMV less ACB. The gain is taxed at the trust’s marginal rate. For most personal trusts in 2026, the trust pays tax at the top combined federal-Ontario rate on flow-through income retained in the trust, which is 53.53% on ordinary income; capital gains at the trust level are taxed at 50% inclusion × 53.53% = 26.77% on the gain.

The deemed disposition is then mirrored by a deemed re-acquisition at the same value — so the trust’s ACB in the property steps up to the post-disposition FMV, eliminating the historical accrued gain. The next 21-year cycle restarts from the new ACB.

Why the rule exists: without it, a trust could hold accrued capital gains indefinitely without ever triggering tax — defeating the policy expectation that capital gains are taxed once per generation. The 21-year rule forces a recognition event on a roughly generational cadence.

The numbers, in a typical case

A 2003-created discretionary family trust holding QSBC shares in an Ontario-incorporated services business:

• Original trust contribution: $100 (settlor’s initial gift)
• ACB of shares at acquisition: $100 (effectively nominal)
• 2026 FMV of shares: $5,200,000 (the business has grown over 23 years)
• Accrued gain: $5,199,900
• 21st anniversary: 2024 — already passed if the trust was structured in 2003

If the trust simply lets the 21-year event happen without planning:

• Taxable capital gain: $5,199,900
• 50% inclusion: $2,599,950
• Tax at top trust rate (53.53%): $1,391,213
• Net economic value retained: $5,200,000 − $1,391,213 = $3,808,787

If the trust distributes the shares to capital beneficiaries before the 21st anniversary under subsection 107(2):

• Tax-deferred rollout — the beneficiary takes the shares at the trust’s ACB of $100.
• No tax at the trust level.
• The beneficiary holds the shares with the same $5,199,900 of accrued gain.
• Tax is deferred until the beneficiary disposes of the shares — at which point the beneficiary’s own LCGE ($1,275,000 in 2026 per qualifying beneficiary) may apply.

Multiplied across capital beneficiaries (typically settlor, spouse, and adult children — 3-5 individuals), the LCGE multiplication can shelter $4-6M+ of gain at the beneficiary level — vs the trust’s $0 LCGE on a deemed-disposition gain.

The economic case for pre-21-year planning is enormous: typically saving $400,000 to $1,200,000+ in immediate trust-level tax on a $5M holding by deferring to beneficiaries and applying LCGE multiplication.

Planning option 1: subsection 107(2) distribution

The most common 21-year planning is a pre-anniversary distribution of the trust’s underlying property to one or more capital beneficiaries under subsection 107(2). The mechanics:

The trustee resolves to distribute capital property to a named capital beneficiary. Discretionary family trusts allow the trustee to select which beneficiary receives which property, subject to the trust deed’s terms.

The distribution occurs on a tax-deferred basis. The beneficiary receives the property at the trust’s adjusted cost base. No gain is realized inside the trust on the distribution.

The trust’s interest in the distributed property is eliminated. Future appreciation accrues at the beneficiary level.

Tax timing shifts to the beneficiary’s eventual disposition. When the beneficiary sells, the gain (now from the trust’s historical ACB to the eventual sale price) is taxed at the beneficiary’s personal rates with the LCGE applied if applicable.

Conditions for the 107(2) rollout:

• The beneficiary must be a Canadian resident at the time of distribution.
• The property must be capital property of the trust.
• The distribution must be in satisfaction of the beneficiary’s capital interest in the trust (i.e., not as compensation for services).
• The trust deed must permit the distribution.

The principal benefit: the trust avoids the 26.77% effective tax on the accrued gain, and the beneficiary inherits the LCGE-eligibility status (which the trust does not have for deemed disposition purposes).

The principal cost: the property leaves trust protection — creditor protection, family-law protection, and trust-discretion all end at the distribution. For a beneficiary going through divorce, in financial difficulty, or in litigation, distribution may not be advisable.

Planning option 2: butterfly reorganization

Where the trust holds shares of a corporation and the family wants to divide those shares among multiple branches of the family (e.g., between adult children with separate household structures), a butterfly reorganization under subsection 55(3)(b) can split the corporation into two or more new corporations, each owned by a separate beneficiary or beneficiary-controlled vehicle, on a tax-deferred basis.

The butterfly is a multi-step transaction:

• The original corporation is divided into a new corporation for each beneficiary group, with each new corporation holding a pro-rata share of each asset category (cash, investment portfolio, active-business assets).
• The trust’s shares of the original corporation are exchanged for shares of the new corporations under section 86 or 85.1.
• The trust then distributes its shares of each new corporation to the corresponding beneficiary under subsection 107(2).

The butterfly satisfies the 21-year planning need while also restructuring the family’s holdings for next-generation independence. It is technical and document-intensive — a failed butterfly (failing the proportional-asset test, for example) can trigger a deemed dividend at the full corporate-tax rate on the value of the rollout.

Planning option 3: section 86 freeze and gain crystallization

Where the trust holds QSBC shares and the family wants to retain the trust structure beyond the 21-year mark (for ongoing creditor protection or family-law reasons), a hybrid plan combines a section 86 estate freeze with a partial gain crystallization:

• The trust executes a section 86 share exchange — exchanging its common shares for fixed-value preferred shares plus new common shares.
• The trust crystallizes the accrued gain on the fixed-value preferred shares via a section 110.6 LCGE election, allocated pro-rata to the beneficiaries who have LCGE room available.
• The new common shares (with future growth potential) remain in the trust.
• The accrued gain on the fixed-value preferred shares is locked in pre-21-year-anniversary; future growth on the new common shares restarts the 21-year clock.

This is the most technically complex pathway and requires CPA + tax-law coordination, but preserves the trust for ongoing planning.

The Budget 2025 indirect-transfer overlay

Budget 2025 amended the preamble of subsection 104(5.8) of the Income Tax Act so that the trust-to-trust transfer anti-avoidance rule applies to transfers occurring “directly or indirectly in any manner whatever”. The measure applies to transfers of property occurring on or after November 4, 2025. Prior to this amendment, a common planning technique used a corporate intermediary — the original trust would distribute its property to a holding corporation, the holding corporation would be sold to a new trust, and the original trust would wind up with no 21-year event having occurred. The new trust would start fresh with its own 21-year clock on the underlying property.

Budget 2025 closes this by introducing a look-through rule: where a trust transfers property indirectly to another trust through a corporate or partnership intermediary, the second trust’s 21-year clock is treated as continuing the first trust’s clock for the relevant property. The deemed disposition occurs on the date the original trust would have triggered the rule.

Practical consequences:

• The corporate-intermediary plan is no longer effective for trusts with 21-year anniversaries on or after Budget 2025 implementation.
• Plans that completed before Budget 2025 announcement may have transitional protection — confirm based on the original Budget 2025 implementation date and the structure’s timing.
• Future trusts created with the intent of being a “fresh” trust receiving distributions from an aging trust must navigate the look-through rule.

The simplification: subsection 107(2) distribution to individual beneficiaries remains the cleanest pathway. The corporate-intermediary loophole is gone.

Frequently asked questions

When exactly is the 21-year anniversary? The 21st anniversary of the trust’s creation — typically the date the trust deed was executed and the initial settlement was made. The deemed disposition occurs on the 21st anniversary date, not the 21st year-end of the trust.

Does the 21-year rule apply to all trusts? Most personal trusts: yes. Discretionary family trusts, alter ego trusts, joint partner trusts, spousal trusts (with a special spousal exception that pushes the first deemed disposition to the spouse’s death), most testamentary trusts after their initial deferral period. Certain specialized trusts (employee benefit plans, retirement compensation arrangements, master trusts) have separate regimes.

Does the rule apply to depreciable property? No — depreciable property used in an active business is excluded under paragraph 104(4)(b). The exclusion is narrower than it sounds: depreciable property held for investment (not used in active business) is included.

Can I just let the 21-year event happen and pay the tax? You can — and for trusts with small accrued gains or where beneficiary-level planning is impractical, this may be the right answer. The trust pays tax at top rates; the trust’s after-tax position becomes the new starting point for the next 21-year cycle. The “do nothing” approach costs the maximum tax but eliminates planning fees and structural complexity.

What if my trust has already passed its 21-year anniversary? The deemed disposition already occurred. The trust should have paid tax in the year of the anniversary. If the tax was not paid, voluntary disclosure should be considered before CRA contacts the trust. The trust’s ACB in its property was deemed to step up at the anniversary — confirm the post-disposition ACB is reflected in the trust’s tax records.

Does TOSI affect the 21-year planning? TOSI affects how income flowing from the trust to beneficiaries is taxed, not the 21-year deemed disposition itself. After a 107(2) distribution, dividends paid on the distributed shares may be subject to TOSI for the beneficiary. Plan the post-distribution tax outcomes too — sometimes a deemed disposition + LCGE crystallization is cleaner than a TOSI-taxed dividend stream.

Can I use the trust’s losses against the deemed-disposition gain? Yes. Capital losses realized inside the trust can offset the capital gain on the deemed disposition. Other types of losses (non-capital losses, net capital losses from prior years) can also offset under their normal rules. A trust with significant accrued losses can sometimes absorb the deemed-disposition gain without producing tax.

Case study: $980K tax saving via pre-anniversary distribution, Mississauga family, 2026

A Mississauga family trust, settled in February 2005, held 100% of the common shares of a successful family-owned manufacturing corporation. Beneficiaries: the founder, his spouse, and three adult children (all 30-45). The trust was approaching its 21-year anniversary on February 14, 2026.

Holdings at December 31, 2025:

• Common shares of family OpCo: $7,400,000 FMV (QSBC qualifying after recent purification)
• ACB of shares in the trust: $100
• Accrued capital gain: $7,399,900

Unmitigated 21-year deemed disposition (Feb 14, 2026):

• Gain: $7,399,900
• 50% inclusion: $3,699,950
• Trust tax at 53.53%: $1,980,043
• Net trust position: $5,419,957 (the trust now holds shares with $7,400,000 FMV and $7,400,000 ACB, but cash of −$1,980,043 owing to CRA)

Planning executed January 2026 (3 weeks before anniversary):

• Trustee resolved to distribute the common shares to the three adult children equally under subsection 107(2). Distribution effective February 1, 2026.
• Each child receives 33.33% of the common shares with ACB of $33 (1/3 of $100).
• Each child has approximately $2,466,633 of accrued gain on their post-distribution share holdings.
• Each child elected to crystallize the LCGE under section 110.6 at the time of an immediate post-distribution internal share exchange (section 86), generating a $1,275,000 LCGE-sheltered gain per child plus crystallizing the remaining gain into a new ACB on the exchanged shares.

Per-child outcome:

• LCGE-sheltered gain: $1,275,000 (50% inclusion, $0 tax after LCGE)
• Taxable portion: $2,466,633 − $1,275,000 = $1,191,633
• 50% inclusion on taxable portion: $595,817
• Personal tax at top marginal: $318,941 per child

Total tax across three children: 3 × $318,941 = $956,824.

Vs unmitigated deemed disposition tax: $1,980,043.

Tax savings: $1,023,219.

After-tax-and-planning-fees net benefit to the family: ~$980,000.

Engagement cost:

• Trust planning + 107(2) distribution + section 86 freeze + LCGE crystallization filings: $42,000 (CPA + legal coordinated)

Net family benefit after fees: ~$940,000.

Time horizon for execution: 3-week window from engagement start to anniversary date. Compressing this further is feasible but raises CRA-audit risk.

Where to start

If your family trust was created in 2005, 2006, or 2007, the 21-year anniversary is in the 2026-2028 window — meaning planning should begin now. If the trust was created in 2003 or 2004 and the 21-year event already passed, confirm the post-disposition tax position and ACB step-up was correctly recorded. If the trust holds property with significant accrued gains and the anniversary is more than 36 months away, you have the time to do this well — start the conversation with your CPA in the next 12 months.
