Key takeaways
  • The tax law treats any trust that is not a testamentary trust as an inter vivos trust.
  • A testamentary trust is generally created on and as a result of a person's death.
  • Ordinary trusts of either kind pay tax at the top individual rate with no graduated brackets, though a graduated rate estate and a qualified disability trust are taxed differently.
  • Trusts are generally deemed to dispose of their non-exempt capital property at fair market value 21 years after the later of January 1, 1972 and the trust's creation, and every 21 years after that.

If you are comparing trusts, you will keep running into two Latin labels: inter vivos and testamentary. They sound technical, but the idea is simple. One kind of trust is set up while someone is alive, and the other comes into being because someone has died.

The label matters because it affects how the trust is taxed, what special rules it can qualify for, and what it can do for a family. This article explains the difference in plain terms. It is general information, and the right choice depends on your facts, so a lawyer or accountant should confirm how it applies to you.

What each label means

For income tax purposes, an inter vivos trust is any trust that is not a testamentary trust. In everyday terms, it is a trust created during a person's lifetime, which is what the Latin phrase means.

A testamentary trust is generally created on and as a result of an individual's death, for example under a will or an estate.

Side-by-side comparison

FeatureInter vivos trustTestamentary trust
How it is definedAny trust that is not testamentaryGenerally created on and as a result of death
Ordinary tax treatmentTax at the highest individual rate, no graduated bracketsOrdinary testamentary trusts also pay at the top rate
Special lower-rate statusNot available for the estate and disability categories, which must be testamentaryGraduated rate estate and qualified disability trust may be taxed at graduated rates
21-year deemed saleApplies to non-exempt capital propertyApplies to non-exempt capital property

The key point many people miss is that an ordinary trust of either type pays tax at the top individual rate, with no graduated brackets. Any lower-rate treatment comes from a specific category, not from the label alone.

Special testamentary categories that can lower tax

Two testamentary arrangements are taxed differently from an ordinary trust. A graduated rate estate is taxed at the same graduated rates as individuals while it qualifies, and it can last up to 36 months after death. To qualify it must be a testamentary trust and meet other conditions.

A qualified disability trust must, at year end, be a testamentary trust arising on a particular individual's death and resident in Canada, and its return must include an election made jointly with one or more beneficiaries. It is elected on Form T3QDT and is taxed at graduated rates, unlike an ordinary trust.

Inter vivos trusts used by older families

Some inter vivos trusts are built for people aged 65 or older. An alter ego trust is set up by a settlor aged 65 or older who is the only person entitled to income or capital during their lifetime. A joint spousal or common-law partner trust is created after 1999 by a settlor aged 65 or older, and the settlor and spouse or partner receive all the income until the later of their deaths.

These trusts have their own tax and property rules, and they can raise Ontario questions such as how real estate is transferred into them. Those details depend on the facts, so get advice before moving a home or investments into one.

Trusts generally face a deemed disposition of their non-exempt capital property at fair market value on the day 21 years after the later of January 1, 1972 and the trust's creation, and again every 21 years after that. Moving property between trusts does not simply postpone that date. Alter ego and joint partner trusts use the death of the settlor or last beneficiary instead.

Which suits which family situation?

There is no single better choice. The question is what you are trying to accomplish and when.

Be careful with disability-related trusts. Other inheritance trusts available for maintenance are subject to a $100,000 combined limit, but that limit does not apply to absolute discretionary trusts. Payments from the trust may still count as income in the month received unless an exemption applies. A person entitled to an inheritance cannot put that inheritance into an absolute discretionary trust to avoid the asset test.

What to do next

Frequently asked questions

Is an inter vivos trust taxed differently from a testamentary trust?

Not in the ordinary case. Both an ordinary inter vivos trust and an ordinary testamentary trust pay tax at the highest individual rate with no graduated brackets. Lower graduated rates are limited to categories such as a graduated rate estate and a qualified disability trust.

How long can an estate be taxed at graduated rates?

An estate can be a graduated rate estate for up to 36 months after death. If it still exists after that, it stops being a graduated rate estate.

Do trusts have to pay tax on their property every 21 years?

A trust is generally deemed to dispose of its non-exempt capital property at fair market value on the day 21 years after the later of January 1, 1972 and the trust's creation, and again every 21 years after, then to reacquire it at that value. Alter ego and joint partner trusts use a death-based date instead.

Can a trust protect a beneficiary on ODSP?

An absolute discretionary trust is treated differently from other trusts under ODSP policy, and it is not counted as an asset. The details of how payments are treated matter, so confirm the plan with a lawyer before relying on it.
