Family Trusts in Canada: What They Are, How They Work, and When They Make Sense

A family trust in Canada is a type of personal (inter vivos) trust created during the settlor’s lifetime, typically to hold assets for the benefit of family members. It is a separate taxpayer under ITA 104, files its own T3 return, and has a December 31 fiscal year-end. The trust itself is not a legal entity (unlike a corporation), but it is a relationship: a settlor transfers property to a trustee, who holds and manages it for the beneficiaries according to the terms of the trust deed. The primary tax uses are income splitting with lower-income family members, estate planning (avoiding probate and controlling asset distribution after death), protecting assets from creditors, and multiplying the lifetime capital gains exemption across family members who hold qualifying small business corporation shares.

What is a family trust and how is it created?

A family trust is created when a settlor (the person establishing the trust) transfers property to a trustee with instructions to hold and manage it for beneficiaries. The “family” part is informal: there is no special legal category of “family trust” in the Income Tax Act. It is simply an inter vivos (living) trust whose beneficiaries happen to be family members. The trust can hold any type of property: cash, investments, real estate, shares of a family corporation, life insurance policies, or other assets.

Creation requires three certainties under Canadian trust law: certainty of intention (the settlor intends to create a trust), certainty of subject matter (the property being transferred is identified), and certainty of objects (the beneficiaries are identified or identifiable). In practice, this means a written trust deed (also called a trust indenture or declaration of trust) prepared by a lawyer, signed by the settlor and trustee, with a schedule listing the initial trust property and identifying the beneficiaries.

The initial settlement is typically a nominal amount ($1 to $100). Substantial assets are then either loaned or gifted to the trust after creation. How the assets get into the trust matters enormously for tax purposes: a gift triggers a deemed disposition at fair market value to the settlor under ITA 69(1)(b), which means the settlor realizes any accrued capital gain at the time of the gift. A loan avoids the immediate gain but creates an ongoing obligation and triggers attribution rules if the loan is not at the CRA’s prescribed rate or higher.

How is a family trust taxed?

Inter vivos trusts are taxed at the highest marginal rate on any income they retain. For 2025, the top combined federal-provincial rate ranges from approximately 48% to 54% depending on the province. There are no graduated rates for inter vivos trusts (unlike testamentary trusts established on death, which got graduated rates restored in 2016 for “graduated rate estates” during the first 36 months).

The planning power comes from allocating income and capital gains to beneficiaries rather than retaining them in the trust. Under ITA 104(6), the trust can deduct amounts that become “payable” to beneficiaries in the year, and those amounts are included in the beneficiaries’ income under ITA 104(13). The character of the income flows through: dividends remain dividends, capital gains remain capital gains, and the beneficiaries report them at their marginal rates. If a beneficiary is in a lower tax bracket (an adult child, a retired parent, a spouse with lower income), the family’s overall tax bill drops.

Since 2018 (the “tax on split income” or TOSI rules under ITA 120.4), income splitting through trusts with minor children and certain family members is restricted. TOSI applies the top marginal rate to “split income” paid to specified individuals (generally family members under 18, and adults who are not actively engaged in the business). Income splitting with adult children over 24 who are actively involved in the family business, or with spouses on non-business income like capital gains on qualifying property, generally remains available. The TOSI rules have made family trust planning more nuanced than it was before 2018; the trust deed and allocation decisions must be designed with TOSI in mind.

What is the 21-year deemed disposition rule?

Every 21 years, a trust is deemed to dispose of all its capital property at fair market value under ITA 104(4). The trust is then deemed to reacquire the property at that same fair market value. This triggers any accrued capital gains at the 21-year mark, even if the trust has not actually sold anything.

The rule exists to prevent trusts from deferring capital gains indefinitely. Without it, property could sit inside a trust for generations, appreciating in value, with no capital gains tax ever paid (because the trust distributes income but never sells). The 21-year rule forces a reckoning.

The 21-year anniversary is measured from the date the trust was created. A trust created on March 1, 2010 faces its first deemed disposition on March 1, 2031. Planning for the 21-year event typically begins several years in advance, because the options for managing the tax hit include distributing property to beneficiaries before the anniversary (a rollout under ITA 107(2) at cost, if the beneficiary is a Canadian resident), selling assets and distributing proceeds, or paying the tax from trust funds.

For family trusts holding shares of a private corporation, the 21-year deemed disposition can be very large if the shares have appreciated significantly. This is one reason family trusts are often used in conjunction with an estate freeze: the freeze fixes the value of the existing shares and issues new growth shares to the trust, resetting the 21-year clock on the growth component.

When does a family trust make sense?

The common use cases, in order of how frequently they appear in practice:

Income splitting with adult family members. The trust earns investment income or receives dividends from a family corporation, and allocates them to beneficiaries in lower tax brackets. Post-TOSI, this works best for capital gains on qualifying small business corporation shares, income allocated to adults over 24 who are involved in the business, and non-business income where the excluded amounts under ITA 120.4(1) apply.

Multiplying the lifetime capital gains exemption (LCGE). Each individual Canadian resident can claim up to $1,250,000 (indexed, for 2025) in capital gains on qualifying small business corporation shares tax-free under ITA 110.6. If a family trust holds the shares and distributes the gain to multiple beneficiaries on a sale, each beneficiary can use their own LCGE. A family of four could shelter up to $5 million in capital gains, compared to $1.25 million for a single owner.

Estate planning and probate avoidance. Property held in a trust does not form part of the deceased’s estate for probate purposes (because the trust, not the individual, owns the property). In provinces with high probate fees (Ontario charges 1.5% of estate value over $50,000), a trust can save significant probate costs on high-value assets. The trust also avoids the delays and publicity of the probate process.

Creditor protection. Assets transferred to a properly structured irrevocable trust are generally beyond the reach of the settlor’s personal creditors (subject to fraudulent conveyance rules and timing). For business owners facing liability risk, a family trust can protect family assets from business creditors. The protection is not absolute: transfers made when the settlor was already insolvent or in contemplation of insolvency can be set aside.

Succession planning. The trust deed controls how and when beneficiaries receive assets. A trust can hold shares of a family business for children who are not yet ready to manage them, distribute income during their education, and release capital at specified ages. This provides control that a direct gift does not.

What are the filing and reporting obligations?

A family trust must file a T3 Trust Income Tax and Information Return annually with the CRA, even if it has no income in the year. The filing deadline is 90 days after the trust’s fiscal year-end (which is always December 31 for inter vivos trusts), so March 31 of the following year.

The trust must report all income, gains, and losses, and issue T3 slips to beneficiaries to whom income is allocated. The T3 slip is the trust equivalent of a T4 (employment) or T5 (investment): it tells the beneficiary and the CRA how much income of each type was allocated.

Since the 2023 tax year, enhanced trust reporting rules (the “bare trust” reporting expansion) require most trusts to file a T3, including trusts that previously were exempt from filing. The trust must also report the identity of all trustees, beneficiaries, and settlors (the “beneficial ownership” schedule). The first year of this expanded reporting was 2024 (for the 2023 tax year), and the CRA subsequently exempted bare trusts from filing for 2023 and deferred certain requirements, but the beneficial ownership reporting is now the ongoing standard.

What are the cross-border complications?

For families with US connections (a US-citizen beneficiary, a US-resident beneficiary, or a US-person settlor), a Canadian family trust creates significant US reporting obligations.

US-person beneficiaries. A US citizen or green card holder who is a beneficiary of a Canadian trust must report distributions on their US return as income (taxed at their marginal rate). They may also have an annual Form 3520 filing obligation to report transactions with foreign trusts (receipt of distributions) and may need to include the trust’s assets on their FBAR and Form 8938 if they have signature authority or a financial interest in trust accounts. The US may treat the Canadian trust as a “grantor trust” or a “non-grantor trust” for US tax purposes, each with different reporting and taxation rules.

US-person settlors or contributors. A US person who transfers property to a Canadian trust may trigger Form 3520 reporting in the year of the transfer, and the trust itself may need to file Form 3520-A annually as a foreign trust with a US owner. The penalties for non-compliance are severe: the greater of $10,000 or 5% of the value of the trust for Form 3520-A failures.

Planning around the cross-border issue. The safest approach for families with US connections is to structure the trust with US reporting in mind from inception. This often means excluding US persons as beneficiaries of certain trusts, or establishing a separate US-compliant trust structure. The cross-border trust interaction is one of the most complex areas in international tax, and generic domestic trust planning done without considering the US angle can create reporting nightmares for US-person family members.
