- Because a single property could be located in a municipality that runs a vacant home tax program and be owned by someone who fell within the federal underused housing tax’s scope, it was possible for both to apply to the same home for 2022 to 2024, or, just as easily, for neither to apply, or for only one to. No underused housing tax is payable, and no return is required, for 2025 and later years.
- A vacant home tax is a municipal charge, adopted city by city, aimed generally at encouraging owners of unoccupied homes to occupy, rent, or sell them.
- The federal underused housing tax operates on a different logic.
Ontario property owners increasingly hear two similar-sounding terms in the same breath: vacant home tax and underused housing tax. They both target empty or underused residential property, and both could apply to the same home for 2022 to 2024; no underused housing tax is payable for 2025 and later years. But they're administered by entirely different levels of government, target different owners, and have entirely separate filing processes — confusing the two, or assuming compliance with one covers the other, is a genuinely common and avoidable mistake.
This article lays out the distinction plainly.
The Short Version
| Vacant home tax | Underused housing tax (UHT) | |
|---|---|---|
| Level of government | Municipal (city-by-city) | Federal |
| Legal basis | Individual municipal bylaws | Federal statute (the Underused Housing Tax Act) |
| Who it generally targets | Broadly, owners of residential property within the participating municipality | Primarily non-resident, non-Canadian owners, though certain non-individual owners (such as some corporations, partnerships, and trustees) could have filing obligations for 2022 to 2024 regardless of residency |
| Who typically files | Most residential owners in a participating municipality, via an annual declaration | Owners who fell within the tax’s scope, via a separate federal filing, for 2022 to 2024 (no return is required for 2025 and later years) |
| Administered by | Each individual municipality | The Canada Revenue Agency |
Because a single property could be located in a municipality that runs a vacant home tax program and be owned by someone who fell within the federal underused housing tax’s scope, it was possible for both to apply to the same home for 2022 to 2024, or, just as easily, for neither to apply, or for only one to. No underused housing tax is payable, and no return is required, for 2025 and later years.
Vacant Home Tax: The Municipal Layer
A vacant home tax is a municipal charge, adopted city by city, aimed generally at encouraging owners of unoccupied homes to occupy, rent, or sell them. The obligation to file an annual occupancy declaration typically applies broadly across residential owners in a participating municipality — Canadian citizens and permanent residents included — regardless of where the owner lives or their citizenship status. It's about how the property is actually used, not who owns it.
Underused Housing Tax: The Federal Layer
The federal underused housing tax operates on a different logic. It's primarily aimed at non-resident, non-Canadian owners of residential property in Canada, on the theory that foreign-owned homes sitting vacant contribute to housing supply pressure in a way the federal government has chosen to specifically discourage through tax policy. Ordinary Canadian citizens and permanent residents who own property in their own name are generally outside the tax's core target, though for 2022 to 2024 the filing rules could still reach certain non-individual owners, such as some corporations, partnerships, or trustees, even when no tax ultimately ends up owing, depending on how the ownership is structured.
Because eligibility and exemption categories under the federal program are technical and depend on ownership structure, this article doesn't attempt to enumerate every exemption — confirm your specific situation against current CRA guidance or with a professional.
Why the Distinction Matters in Practice
- They're not interchangeable filings. Filing your municipal vacant home tax declaration does not satisfy any federal underused housing tax obligation, and vice versa. They're entirely separate systems with separate forms, separate portals, and separate deadlines.
- They target different risk profiles. A Canadian homeowner who simply doesn't live in a second Ontario property full-time may squarely face a municipal vacant home tax question, with little or no federal underused housing tax exposure. For 2022 to 2024, a non-resident owner of a Canadian investment property may have faced the opposite pattern, or both at once.
- Corporate and trust ownership needs particular attention. Ownership structures that are common in investment real estate — holding companies, trusts, certain partnerships — could trigger federal filing obligations for 2022 to 2024 that wouldn’t necessarily apply to the same property if owned by an individual outright.
- Neither substitutes for ordinary property tax. Both of these are charges layered on top of, and separate from, standard municipal property tax, which continues regardless.
A Practical Way to Think About It
Ask two separate questions about any Ontario property you own but don't live in full-time:
- Is the property located in a municipality that runs a vacant home tax program? If so, you likely have an annual municipal declaration obligation, regardless of your citizenship or residency.
- Does the ownership structure fall within the federal underused housing tax's scope? For 2022 to 2024, this turned on who or what owned the property, including whether an individual owner was a Canadian citizen or permanent resident, and on how the property was used; no tax is payable for 2025 and later years.
Answering "no" to one doesn't answer the other. Both need to be considered independently.
Frequently asked questions
If I already pay the municipal vacant home tax, do I still need to worry about the federal underused housing tax?
For 2022 to 2024, potentially yes, they’re assessed independently based on different criteria. No underused housing tax is payable, and no return is required, for 2025 and later years. Paying one doesn't exempt you from the other; you need to evaluate both separately for your specific property and ownership structure.
I'm a Canadian citizen who owns a rental property through a corporation — does the federal tax apply to me?
For 2022 to 2024, ownership through a corporation could trigger a federal filing obligation even where an individual Canadian owner wouldn’t have one, depending on the specifics; no return is required for 2025 and later years. This is worth confirming with a tax professional given how technical the ownership-structure rules are.
Does the underused housing tax apply only to residential property in cities with a vacant home tax?
No — the federal program's scope is based on the type of residential property and ownership structure, not on whether the local municipality happens to also run its own vacant home tax program. A property in a municipality with no vacant home tax at all could still have fallen within federal underused housing tax rules for 2022 to 2024.
Who do I contact if I'm not sure which of these applies to me?
For the municipal vacant home tax, start with your specific municipality. For the federal underused housing tax, CRA is the administering body. A real estate or tax lawyer can help you work through how both apply to your specific ownership situation.
