Underused Housing Tax Canada: Who Must File and Who Pays

The federal Underused Housing Tax (UHT) created significant confusion when it launched in 2022, primarily because the CRA's initial communication made it sound like a universal obligation. It is not — but the filing requirement extends further than the actual tax liability, which is where many property owners got caught.

Here is who owes the tax, who must still file a return without owing tax, what the exemptions look like, and how the UHT interacts with Ontario's other vacancy-related obligations.

What the UHT Is

The Underused Housing Tax is a federal 1% annual tax on the ownership of vacant or underused residential real estate in Canada. Unlike provincial programs, which target all owners (including Canadians) for filing purposes, the UHT was specifically designed to target foreign ownership of Canadian residential property.

The tax is levied annually on the property's fair market value — not the assessed value, not the purchase price. It is reported and paid to the Canada Revenue Agency using Form UHT-2900 (Underused Housing Tax Return and Election Form), filed by April 30 of the following year.

The first filing year was 2022, covering residential property ownership as of December 31, 2022. The program has been in effect since then, with minor adjustments to exemption categories and administrative guidance in subsequent years.

Who Must File a UHT Return

This is where the confusion originated. The UHT distinguishes between who is an "affected owner" (required to file) and who is an "excluded owner" (no filing required at all).

Excluded owners — no filing required:

• Canadian citizens
• Canadian Permanent Residents
• Public Canadian corporations
• Canadian municipalities, governments, and bodies established by provincial statute

If you are a Canadian citizen or Permanent Resident who owns residential property directly in your own name, you are an excluded owner. You do not need to file a UHT return, and the tax does not apply to you.

Affected owners — must file, but may qualify for exemption:

• Foreign nationals who own residential property in Canada
• Canadian private corporations where one or more foreign individuals or corporations hold 10% or more of the shares
• Partners in a partnership where a foreign national is a partner
• Trustees of trusts with foreign beneficiaries or trustees
• In some cases, certain Canadian private corporations even where all shareholders are Canadian

The category of "affected owner" is broader than most people expect. A Canadian-controlled private corporation — even one with all-Canadian shareholders — may be an affected owner and required to file, though it will typically qualify for an exemption from the actual tax. The filing obligation itself remains.

Exemptions From the Tax (But Not From Filing)

Affected owners who file but meet an exemption condition owe no tax. The exemptions cover several categories:

Occupancy exemptions:

• The property is occupied for at least 180 days in the calendar year by the owner or their spouse as a principal place of residence
• The property is occupied for at least 180 days by a qualifying tenant under a written rental agreement (a fixed-term lease of at least one month, or a month-to-month tenancy)
• The property is used by a specified Canadian or their spouse as a place of work for at least 180 days

Availability exemptions:

• The property was listed for sale and genuinely available to purchase for the majority of the year
• The property is newly constructed and was not occupied for the first time until the year in question

Ownership structure exemptions:

• The property is owned by a specified Canadian entity (certain categories of trust, partnership, or corporation)

Geographic exemptions:

• Properties in rural areas or small communities (below specified population thresholds) are in some cases exempt

For investment property owners in Ontario who are foreign nationals or who own through structures that make them "affected owners," the most relevant exemption is the qualified tenancy exemption: a property that is tenanted on a genuine fixed-term or month-to-month basis for at least 180 days in the year qualifies for the exemption, provided the lease is in writing and at arm's length.

This means that an investment property with a continuous, documented tenancy — the most common scenario for landlords operating compliant residential rentals — is exempt from the UHT tax liability. But the affected owner must still file the return and claim the exemption. Filing without claiming an exemption equals filing as a taxpayer owing 1% of fair market value.

Late Filing Penalties

The CRA imposes penalties for late filing of the UHT return that are disproportionately large relative to the underlying tax. For individuals, the minimum penalty for filing late is $5,000. For corporations, the minimum late-filing penalty is $10,000. These penalties apply even if the return would have shown $0 in tax owing.

This penalty structure produced substantial surprise billing in 2022 and 2023, when affected owners who owed nothing in UHT discovered that missing the April 30 filing deadline triggered a minimum $5,000 fine regardless.

How the UHT Differs From Toronto's Vacant Home Tax

The UHT and the Toronto Vacant Home Tax are separate programs with different administrators, different tax bases, different filing deadlines, and different exemption structures.

A foreign national who owns a vacant property in Toronto potentially faces both taxes simultaneously: the federal UHT at 1% of market value and the Toronto VHT at 3% of CVA. These are separate calculations with separate filing obligations.

Canadian citizens and Permanent Residents who own investment property in Toronto face only the VHT obligation (annual City declaration) — not the UHT, because they are excluded owners for federal purposes.

What This Means for Ontario Investment Property Owners

For the majority of Canadian investors — citizens and PRs owning residential rental property directly in their own names — the UHT is not a filing obligation and not a tax liability. You are an excluded owner.

For investors who own property through corporations (even Canadian-controlled ones), through trusts, or who are not Canadian citizens or PRs, the UHT filing obligation applies and careful attention to the exemption categories and filing deadline is required.

For foreign nationals or non-resident owners, the interaction of the UHT (federal, annual, 1%), the VHT if the property is in Toronto (municipal, annual, 3%), and the NRST that was paid at purchase (provincial, one-time, 25%) represents the full tax burden stack facing foreign-owned vacant residential property in Ontario.

If you own Ontario residential investment property through an entity structure or are a non-resident investor, confirm your UHT status with a Canadian tax professional before April 30 each year. The $5,000 minimum late-filing penalty is not recoverable.

For residents and citizens building investment portfolios in Ontario, the more directly relevant compliance framework is the standard rental income reporting on the T776, the annual Toronto VHT declaration if applicable, and the 2026 OSFI mortgage regulations. The Ontario Investment Property Guide covers these in detail alongside the transaction mechanics, financing structure, and tenant management rules.
