My family trust is turning 21. What do the trustees need to do now?

What actually happens at the 21-year mark

On the trust's 21st anniversary, the Income Tax Act deems it to have sold and reacquired its capital property at fair market value. Every unrealized gain — most often on private company shares the trust has held since a long-ago estate freeze — becomes taxable in that year, and a trust pays tax on gains at the top personal rates. There is no grandfathering, no election to skip it, and no CRA discretion to extend it; the rule exists precisely so families cannot defer gains across generations forever.

The scale is what surprises trustees. A trust that received growth shares worth a nominal amount at a freeze twenty years ago may now hold shares worth several million dollars with essentially no cost base. Only half of a capital gain is taxable, but the tax is real money — and the trust often holds no cash to pay it, because its only asset is the shares themselves. That combination, a large paper gain inside an illiquid trust, is the whole reason this deadline gets planned for rather than absorbed.

The rule then repeats every 21 years for as long as the trust exists. If you are new to how these structures work, family trusts for business owners in Canada covers the architecture; this page is about the deadline.

The rule catches trusts generally, though the timing varies by type. An ordinary discretionary family trust, the kind created for an estate freeze or income planning, faces the deemed disposition on its 21st anniversary. Spousal, alter ego and joint partner trusts run on a different clock tied to the death of the relevant person, after which the 21-year cycle begins. What is caught is the trust's capital property: private company shares, real estate, investment portfolios — broadly, the assets carrying accrued gains.

First, establish your real date and what the deed allows

The first concrete task is to confirm the trust's actual 21st anniversary, because the clock runs from the trust's creation — the date it was settled — not from a tax year, a freeze date, or when assets arrived. Pull the trust deed and find the settlement date; the deemed disposition falls on the day of the anniversary, and everything else backs up from it. Trustees are sometimes a year off in either direction, and both errors are expensive.

Then read the deed like it is the rulebook, because it is. The questions that decide what is even possible:

• Who are the capital beneficiaries — the people entitled to receive trust property, as opposed to income only?
• Do trustees have discretion over who receives capital and in what shares, or is it fixed?
• Are there restrictions — ages, consents, classes of beneficiary that were never intended to receive shares?
• Where does everyone live? A beneficiary who has become a non-resident of Canada changes the plan materially.

At the same time, inventory the assets and their history: what the trust holds, each asset's cost base, and whether any property was ever subject to the attribution rule that applies when a contributor could get property back. That taint, where it exists, blocks the tax-deferred rollout for most beneficiaries, and you want to know it two years out, not two months out. This trust asset review, the deed review and the anniversary date are the foundation; every option below stands on them.

The trustees' realistic options before the anniversary

The standard answer is a rollout: distribute the trust's capital property to Canadian-resident capital beneficiaries before the anniversary, which subsection 107(2) lets happen at cost, with no tax to the trust or the beneficiary at that moment. The gain does not disappear — each beneficiary inherits the trust's low cost base and will pay tax when they eventually sell — but the 21-year tax is avoided and the clock stops mattering. The realistic menu looks like this:

What is not on the menu: rolling the property to a brand-new trust to restart the clock — the rules count the years of the old trust — and rolling out to a corporation, since the tax-deferred rollout is for beneficiaries who are individuals or certain trusts, not a holdco added for convenience. Where the family's real goal is a corporate structure, that is a different reorganization with its own tax analysis; family trust or holding company sets out which vehicle does which job.

If the family does decide to absorb the tax — sometimes right where gains are modest, beneficiaries live abroad, or the trust's protection is worth keeping — plan the funding as its own project. The trust usually has to be put in funds: a dividend from the company, a redemption of some of its shares, or a sale of part of the portfolio, each with its own tax cost layered on top of the deemed gain. The one mistake worse than paying the 21-year tax is paying it twice by funding it badly. There is a consolation, though: property that passes through the deemed disposition emerges with a stepped-up cost base for the future.

Combinations are common in practice. Trustees might roll operating-company shares out to the adult children who work in the business, accept the deemed disposition on a small marketable-securities portfolio the trust can afford to pay tax on, and redeem enough shares to fund the bill. The right mix is a valuation exercise plus a family-governance exercise, which is why it cannot be assembled in the final quarter.

The facts that change the answer

Six facts do most of the deciding, and trustees should establish all of them before choosing a route:

• Where every beneficiary lives. The rollout is effectively denied for non-resident beneficiaries — a distribution to them generally triggers tax as if sold. A child who moved abroad since the freeze reshapes the plan.
• Whether the attribution taint ever applied. If property could revert to a contributor, the rollout is blocked for most recipients, and specialist advice is needed early.
• Who should actually own the shares. A rollout puts company shares directly into beneficiaries' hands — into their marriages, their creditor exposure and their estates. Sometimes the family concludes the protection of the trust is worth more than the deferral and plans to pay some tax instead.
• Future dividends and the split-income rules. After a rollout, dividends to a beneficiary who does not work in the business roughly 20 hours a week can be taxed at the top rate under the tax on split income rules. Who receives shares should reflect who works.
• The exemption math. Shares rolled out to individuals can position each of them to claim the $1.25 million lifetime capital gains exemption on a future sale, where the company qualifies — often the biggest prize in the whole exercise, and covered in should a family trust own shares of my business.
• The asset mix. Marketable securities are easy to value and cheap to roll or tax; private company shares need a business valuation; farm property brings its own intergenerational rollover rules — relevant for the farm corporations we work with through farm business incorporation.

Notice that only two of the six are strictly tax facts. The 21-year decision is succession planning under a deadline, which is why it deserves the same care as the original freeze.

A working timeline from about two years out

Two years of runway is comfortable, one is workable, and a few months is triage — because the slowest steps sit with other people. A defensible business valuation takes months, especially with a fiscal year-end to wait for. Legal work — trustee resolutions, share transfers, deed interpretation, sometimes a court application if the deed is unclear — takes more. Beneficiary conversations take longest of all, and they are the step families defer.

A sensible sequence for trustees starting around year 19 or 20:

• Confirm the anniversary date and calendar it; brief all trustees on what the rule does.
• Complete the deed review and asset inventory, including residence checks on every beneficiary and any attribution history.
• Commission the valuation of private company shares and other hard-to-value property.
• Choose the route — rollout, pay, reorganize, or a mix — with the after-tax math for each beneficiary in front of you.
• Execute early: legal resolutions, share registers updated, transfers dated well before the anniversary, not the week of it.
• File properly. The trust's T3 returns, with the expanded beneficial-ownership disclosure now required of most trusts, must reflect the distributions; late or inconsistent filings invite exactly the review you do not want in a rollout year.

Trustees should also weigh what the trust costs to keep against what it still delivers, because the anniversary is a natural decision point. Annual T3 filings with beneficial-ownership disclosure, valuation refreshes, trustee meetings and professional fees are the running cost; creditor protection, control over immature beneficiaries and exemption multiplication are the running benefit. Where the benefits have expired because the children are grown and the succession is settled, the anniversary is the obvious moment to roll everything out and wind the trust up rather than buy another cycle of administration.

The personal stake for trustees is worth naming plainly. Trustees who let the anniversary pass unplanned have converted a manageable project into a tax bill at top rates, and beneficiaries have been known to ask, later and with lawyers, why. Diarizing the date, taking advice in good time and papering the decisions is not just good tax practice; it is how trustees discharge the duty they signed up for.

This is defined-scope work for a business estate planning CPA in Ontario working alongside the family's lawyer: we handle the valuation coordination, the option modelling, the tax filings and the after-tax math, and we run it as a Strategic Project with a written scope and fee through our estate and succession planning practice. If your trust was settled around twenty years ago, the honest advice is unglamorous: book the deed review this quarter, and give the anniversary the two years of respect it demands.
