What is a family trust in Canada?

A family trust is a legal arrangement where a trustee holds assets for the benefit of family members (beneficiaries). It is commonly used for income splitting, estate planning, business succession, and asset protection. The trust itself is a separate legal entity for tax purposes.

How much does it cost to set up a family trust in Canada?

Setting up a family trust typically costs $3,000 to $10,000+ in legal fees. Additional costs include annual tax returns ($500–$2,000), potential accounting fees, and ongoing administration. Trusts only make financial sense when tax savings exceed these costs.

Can a family trust reduce taxes in Canada?

Yes, family trusts can reduce taxes through income splitting — distributing income to beneficiaries in lower tax brackets. However, the Tax on Split Income (TOSI) rules significantly limit this for minor children and many adult family members working in family businesses.

What is the 21-year rule for family trusts?

Every 21 years, a family trust has a "deemed disposition" where it is treated as having sold all capital property at fair market value. This can trigger significant capital gains tax. Planning for this event is crucial for trusts holding appreciated assets.

What Is a Family Trust?

A family trust is a legal arrangement with three parties:

Party	Role
Settlor	Creates the trust and transfers initial assets
Trustee(s)	Manages the trust and makes decisions
Beneficiaries	Family members who receive income or capital

The trust holds assets separately from the settlor’s estate, with income and capital distributed according to the trust agreement.

Types of Family Trusts

Inter Vivos (Living) Trust

Feature	Inter Vivos Trust
Created	During settlor’s lifetime
Tax rate	Top marginal rate (unless distributed)
Purpose	Income splitting, asset protection
21-year rule	Applies

Testamentary Trust

Feature	Testamentary Trust
Created	Through a will, upon death
Tax rate	Graduated rates (certain trusts)
Purpose	Estate planning, minor beneficiaries
21-year rule	Applies from date of creation

Benefits of Family Trusts

Tax Planning

Benefit	How It Works
Income splitting	Distribute income to lower-bracket family members
Capital gains planning	Multiply capital gains exemptions
Dividend splitting	Canadian dividend tax credit to beneficiaries
Tax deferral	Hold appreciated assets without triggering gains

Asset Protection

Benefit	How It Works
Creditor protection	Properly structured trusts can protect assets
Marital protection	Assets stay in family bloodline
Spendthrift protection	Control distributions to beneficiaries
Cottage succession	Avoid forced sale for estate taxes

Estate Planning

Benefit	How It Works
Avoid probate	Trust assets don’t go through probate
Privacy	Trust arrangements are not public
Controlled distribution	Specify timing and conditions
Multi-generational	Pass wealth across generations

Tax on Split Income (TOSI) Rules

The TOSI rules (nicknamed “kiddie tax”) significantly limit income splitting; related attribution mechanics are covered in attribution rules in Canada:

Who Is Subject to TOSI?

Category	TOSI Applies?
Minors (under 18)	Yes — almost all split income
Adults 18–24	Yes — unless excluded
Adults 25+	Yes — unless excluded
Spouse	Yes — unless excluded

TOSI Exclusions for Adults

Exclusion	Requirement
Excluded business	Not related to family business
Excluded shares	Prescribed amount of labour/capital
Arm’s length capital	Market-rate return on capital
Safe harbour capital return	5-year GIC rate

Impact of TOSI

Situation	Income Tax Rate
Income subject to TOSI	Top marginal rate (~50%)
Excluded income	Beneficiary’s own rate

TOSI makes income splitting through trusts much less effective than before 2018.

Setting Up a Family Trust

Steps

Determine objectives — Income splitting? Estate planning? Asset protection?
Choose trustees — Family members? Professional trustee?
Select beneficiaries — Who can receive income/capital?
Draft trust deed — Lawyer prepares legal document
Settle the trust — Transfer initial asset (often $1)
Fund the trust — Transfer assets or have trust subscribe for shares

Costs

Item	Cost Range
Trust deed (legal)	$3,000–$10,000+
Annual tax return	$500–$2,000
Accounting advice	$500–$2,000/year
Trustee fees (if professional)	0.5–1% of assets

21-Year Deemed Disposition

What Happens

Every 21 years from the trust’s creation, there’s a deemed disposition:

Effect	Impact
Capital property	Deemed sold at FMV
Capital gains	Triggered and taxable
Trust pays tax	At top marginal rate
Can’t defer further	Must address within 21 years

Example

Asset	Original Cost	FMV at 21 years	Gain
Family cottage	$200,000	$1,200,000	$1,000,000
Taxable (50% inclusion)	—	—	$500,000
Tax at top marginal rate (~50%)	—	—	~$250,000

Planning Strategies

Strategy	How It Works
Distribute to beneficiaries	Transfer assets before 21 years
Trigger gains strategically	Use beneficiaries’ exemptions
Purchase insurance	Fund tax liability
Roll out	Transfer to new trust (careful planning)

Family Trust for Business Owners

Holding Company Shares

Structure	Benefit
Trust owns holdco shares	Multiple shareholders for dividends
Income splitting	Distribute dividends to beneficiaries
LCGE multiplication	Each beneficiary uses their exemption
Succession	Transfer to next generation

Lifetime Capital Gains Exemption

2026 LCGE	Amount
Qualified small business shares	$1,120,000+
Multiplied by beneficiaries	Each eligible beneficiary gets exemption

Example: A family of 4 beneficiaries could shelter $4.5M+ in gains.

Restrictions

Rule	Impact
TOSI	Limits income splitting
Attribution rules	May attribute income back to settlor
Qualified shares	Must meet QSBC criteria
Trust as shareholder	Must structure carefully

Trust Taxation

Income Retained in Trust

Income Type	Tax Rate
Interest, regular income	Top marginal (~50%)
Canadian dividends	Top rate with dividend credit
Capital gains	Top marginal on 50% inclusion

Income Distributed to Beneficiaries

Income Type	Tax Rate
All income types	Beneficiary’s marginal rate
Character maintained	Dividends flow as dividends
Capital gains	Flow as capital gains

Trusts generally want to distribute income to avoid top-rate taxation.

Attribution Rules

Attribution Back to Settlor

Situation	Attribution?
Transfer to spouse’s trust	Yes — income attributes back
Transfer to minor’s trust	Yes — income attributes back
Loan at prescribed rate	May avoid if interest paid
Gift to adult non-spouse	Generally no

Avoiding Attribution

Strategy	Requirement
Prescribed rate loan	Charge at least CRA rate (5.00% for 2026)
Pay interest annually	By January 30 of following year
Business investment	May avoid if genuine business

Trust Return Filing

T3 Trust Income Tax Return

Requirement	Details
Filing deadline	90 days after year-end
When required	Tax owing, dispositions, distributions
Information slips	T3 slips to beneficiaries
Trustee responsibility	Must file accurate return

Penalties

Violation	Penalty
Late filing	5% plus 1%/month (max 12 months)
False statement	50% of tax evaded
Failure to file	$25/day (min $100)

When a Family Trust Makes Sense

Good Candidates

Situation	Benefit
Own a business	LCGE multiplica tion, succession
