The Family Trust Nobody Told the Tax Filer About

A Markham couple held their daughter's home in a family trust for good reasons. Nobody realized the trust itself had a federal housing tax return due — until a routine check caught it in time.

The situation

Adaeze, a university professor, and Giulia, a professional engineer, had bought a house in Markham several years earlier for their daughter Lucia to live in. Lucia worked as a gig economy driver, piecing together rideshare and delivery jobs while she built up savings and credit history toward eventually owning a place of her own. Rather than putting the house directly in Lucia's name, Adaeze and Giulia's accountant at the time had suggested holding it in a family trust, with Adaeze and Giulia as trustees and Lucia as the beneficiary who would live there. The arrangement made sense for estate planning: it kept the property out of Lucia's name for creditor and matrimonial protection reasons while she was still early in her working life, and it let her parents control the timing of an eventual transfer.

The couple came to Treadstone Law after a friend mentioned a newer federal filing called the Underused Housing Tax, wondering aloud whether it might apply to a second property that wasn't their own primary residence. Adaeze and Giulia weren't sure the tax had anything to do with them — the house wasn't vacant, and Lucia lived there full time. They asked for a straightforward compliance review: did they need to file anything, and if so, what.

What the review found

The Underused Housing Tax was introduced to discourage foreign owners from leaving Canadian residential property vacant, and most Canadian homeowners never need to think about it. The tax applies annually, calculated as a small percentage of a property's value, unless the owner is exempt. But the filing obligation is broader than the tax itself. An individual Canadian citizen or permanent resident who owns a home directly in their own name is treated as an excluded owner and has no filing obligation at all, regardless of how the property is used.

Trustees are not excluded owners. Because the Markham property was registered in Adaeze and Giulia's names as trustees of a family trust rather than in their personal capacities, they fell into a separate category — affected owners — who must file an annual return for the property whether or not any tax ends up being owed. Their accountant's estate planning advice had been sound on its own terms; nobody along the way had connected it to this newer federal filing requirement, because the trust was set up before the tax existed and nothing about day-to-day life at the property had changed since.

The good news was that the review also found a solid basis for an exemption. The tax includes relief for a property occupied by a qualifying occupant — broadly, an individual who lives in the home for an extended period under an arrangement evidenced in writing, including an adult child of the owner. Lucia's residency fit that description, and the original trust deed itself, along with bank and utility records showing her living at the address year-round, supported the claim. The problem wasn't that the family owed the tax. The problem was that nobody had filed the paperwork proving they didn't — and the filing itself was already overdue for more than one prior tax year, with the deadline for the current year approaching fast.

What we did

  1. Confirmed the trust's filing status. We reviewed the trust deed and land registry documents to confirm that both Adaeze and Giulia, as registered trustees, were separately required to file — not just the trust as an abstract entity, but each named trustee individually for their share of the property.
  2. Identified every year requiring a return. The tax had applied since it came into force, and the family had not filed for any prior year. We mapped out which years were already late and which return was still due on time, so nothing was missed and nothing was filed twice.
  3. Assembled the exemption evidence. We gathered the documentation needed to support the qualifying occupant exemption for each year in question: the trust deed naming Lucia as beneficiary, records showing her address history at the property, and a written confirmation of the arrangement consistent with what the exemption requires.
  4. Filed the outstanding returns before the current deadline. We prepared and filed the late returns for the prior years alongside the current year's return, claiming the qualifying occupant exemption throughout, so that all of the family's obligations were brought current in a single coordinated filing rather than trickling in piecemeal.
  5. Set up an annual reminder. Because the filing obligation repeats every year as long as the trust holds the property, we flagged the recurring deadline for Adaeze and Giulia so a future year couldn't slip through the same way the earlier ones had.

The outcome

All of the outstanding returns were filed before the current year's deadline, each one claiming the qualifying occupant exemption. No tax was owed on the property for any year, and because the returns were filed before the Canada Revenue Agency identified the gap on its own, no penalty applied either. Had the family not caught the issue, the exposure would have been real: the failure-to-file penalty applies to each trustee separately, for each year missed, whether or not any tax was ultimately payable, and the property's value in Markham put the combined exposure for two trustees across multiple missed years somewhere in the range of roughly $150,000 to $400,000 once the value-based component of the penalty was added to the flat minimum for each owner and each year. That figure was never charged, because the returns went in before it could be assessed — but it is the number the family avoided, not one they paid.

Adaeze and Giulia now file the return every year as a routine matter, usually within an hour of pulling together the documents, since the underlying facts rarely change year to year. Lucia, for her part, still lives in the house and still hadn't heard of the tax at all until her parents mentioned it — which is exactly the kind of gap this case closed. The trust continues to serve its original estate planning purpose; it simply now also does the federal paperwork that comes with it.

What made the difference here was timing rather than any complicated legal argument. The exemption Adaeze and Giulia relied on was always available to them; the facts supporting it — Lucia's residency, the trust deed, the paper trail showing the arrangement was genuine — had existed since the day the trust was set up. What had been missing was simply the act of filing to claim it. Once the review flagged the gap, closing it was a matter of weeks, not months, because none of the underlying evidence had to be created after the fact. That is generally true of Underused Housing Tax exposure: the hard part is almost never proving the exemption applies, it is realizing in the first place that a return needs to be filed at all.

The couple also asked, reasonably, why their accountant hadn't flagged it originally. The honest answer was that the trust predated the tax by several years, and the accountant's engagement had never been renewed to include an annual look at new federal filing obligations tied to how title was held. It is a common gap: professionals are typically retained for a specific task at a specific moment, and a new tax that touches an old structure can fall into the space between engagements unless someone is specifically asked to look for it.

What you can learn from this

  • Owning residential property through a trust, a partnership, or most Canadian corporations removes the automatic exemption available to individual owners — a filing is required even when no tax is ultimately owed.
  • The Underused Housing Tax filing obligation attaches to each trustee or owner individually, not just to the property once, which means the penalty exposure multiplies with every owner and every missed year.
  • An exemption from the tax itself does not excuse the filing. The return still has to be submitted to claim it, and claiming it late after the CRA notices the gap is a very different position than filing on time.
  • Estate planning advice given years ago can quietly collide with newer tax rules. A structure that made sense when it was set up is worth revisiting whenever a new filing regime comes into effect.
  • If a property is held through any structure other than personal ownership, it is worth checking whether a Underused Housing Tax return is due — the filing deadline is annual, and it does not send a reminder.
