An investor client and a vacancy shock

Anonymised, illustrative composite. An investor client’s condo sat empty between tenants for a renovation — and came within days of a tax the investor did not know existed, on a technicality that had nothing to do with the renovation itself.

At a glance

  • • Toronto investment condo, Current Value Assessment $620,000, tenant moved out and the unit sat unrented for a cosmetic-plus-plumbing renovation.
  • • Toronto’s Vacant Home Tax is 3% of a property’s Current Value Assessment for any unit not occupied at least six months in the year — $18,600 on this unit, in full, if it applied.
  • • The renovation exemption requires occupancy to have been prevented for six months or more, all necessary permits to have been issued, and the city satisfied the work was actively underway without unnecessary delay — three tests, not one.
  • • The permits were still moving through the city’s approval queue when the annual declaration deadline of April 30 was days away.

The situation

An investor client bought a downtown Toronto condo as a rental two years earlier, through the same agent who had helped find the tenant. When that tenant moved out, the investor decided to use the vacancy to do a renovation before re-listing for rent — new flooring, paint, and relocating a bathroom fixture that required a permit.

The problem

The investor assumed “the unit is vacant because we’re renovating it” was self-evidently exempt from anything, and had never heard of Toronto’s Vacant Home Tax at all. The city’s own program requires every residential property owner to declare occupancy status annually, by April 30, whether or not the unit was occupied — and a property with no tenancy agreement of at least 30 days totalling six months or more in the year is, by default, a vacant property for the purposes of the tax. The renovation itself does not exempt anything on its own.

The numbers

Toronto’s Vacant Home Tax rate is 3% of a property’s Current Value Assessment, effective for the 2024 taxation year onward. On this unit’s $620,000 assessment, that is $18,600 — billed in three equal instalments, and if a declaration is never filed, the city simply assumes the property was vacant and issues a Notice of Assessment for the full amount, no benefit of the doubt included.

The rule that decided it

The agent caught this in March, ahead of the April 30 declaration deadline, during a spring check-in call about re-listing the unit for rent once the work wrapped up. The renovation exemption Toronto actually offers has three conditions, not one: occupancy must have been prevented by the work for at least six months of the taxation year; all necessary permits must have been issued, not merely applied for; and the city must be satisfied the repairs are being “actively carried out without unnecessary delay.” The investor’s permit for the plumbing relocation was still working its way through the city’s queue — applied for, not yet issued — with the April 30 deadline a few weeks away.

The distinction the agent flagged was blunt: an exemption claimed on permits that are pending, not issued, is not the exemption Toronto’s own criteria describe. The investor’s contractor expedited the application, and the permit came through with about ten days to spare before the declaration deadline.

The outcome

The investor declared by April 30 claiming the renovation exemption, with the issued permit number, contractor invoices, and dated photos of the work in progress attached as supporting documentation. No Vacant Home Tax bill was issued. The unit was re-listed and re-tenanted about six weeks later.

What it would have cost otherwise

Had the investor simply not declared — on the assumption that an obviously-under-renovation unit would be obviously exempt — the city would have defaulted to a Notice of Assessment for the full $18,600, due in three instalments, with a Notice of Complaint as the only route to dispute it. That dispute would have required the exact same documentation the investor ultimately gathered anyway, now filed reactively under audit scrutiny rather than proactively with the declaration, and with interest accruing at 1.25% per month on any unpaid balance while the dispute sat open.

The audit backstop

Even a clean declaration is not the end of the paper trail. Toronto’s program can select a filed declaration for audit and request supporting evidence, giving the owner 60 days from the date of the request to respond, and it requires records related to a property’s occupancy or any exemption claimed to be retained for no less than three years. The investor’s contractor invoices and permit paperwork now live in a labelled folder for exactly that reason, not just for this year’s declaration.

The tell

A rental unit that goes unrented across a filing year’s six-month occupancy test is a Vacant Home Tax event by default — “we’re renovating” is a reason, not the exemption itself. Any investor client whose unit sits empty for a stretch that straddles a calendar year-end should get an April 30 reminder on the calendar the same way a mortgage renewal date would, and any renovation-based exemption plan needs the word “issued,” not “applied for,” next to every permit before the declaration goes in.

Takeaways

  • • Toronto’s Vacant Home Tax is 3% of Current Value Assessment, billed by default on any property not declared, or not occupied at least six months in the year.
  • • The renovation exemption needs permits already issued by declaration time, evidence the work is genuinely underway, and at least six months of prevented occupancy — all three, not one.
  • • Missing the April 30 declaration does not mean missing the tax question; it means answering it later, under audit, with interest running.
  • • Keep exemption evidence — permits, invoices, dated photos — for at least three years, since a clean declaration can still be selected for a 60-day audit response.
