1% Underused Housing Tax (UHT)—Filing Deadline May 1, 2023

The Underused Housing Tax Act received royal assent on June 9, 2022, and was deemed to come into force on January 1, 2022. This act implements a 1% annual tax on underused or vacant housing.

While the act targets non-resident owners, it includes provisions that may require Canadian owners to file the UHT-2900 Underused Housing Tax Return and Election Form, even if they are exempt from paying the Underused Housing Tax (UHT). This includes many Canadian corporations (including CCPCs), trustees of a trust and partners in a partnership.

We have included the UHT-2900 in the TaxCycle Forms module.

UHT-2900 in TaxCycle

In TaxCycle, we have added an excluded owners work chart at the top of form UHT-2900 to help you determine whether the taxpayer generally meets the definition of:

  • an excluded owner who is not required to file a UHT return, or
  • an affected owner who must file a return for the 2022 calendar year, and annually thereafter, as long as they remain an affected owner.

The checklist does not cover all situations. It is a general guide only. Please refer to the Canada Revenue Agency’s Underused Housing Tax Notice UHTN1 for detailed definitions.

Filing and Payment Deadline

The deadline for filing and payment of any UHT owing is April 30 and is based on the property owned at December 31 of the calendar year. However, since that date falls on a Sunday this year, the deadline this year is May 1, 2023.

An affected owner may qualify for certain exemptions, in which case no tax would be payable on the property, but a return must still be filed.

Filing Requirements

  • Each affected owner or corporation must file a separate return.
  • If the affected owner (whether an individual or corporation) owns multiple residential properties, a separate return must be filed for each residential property.

For example, if three individuals jointly own three separate properties as partners of a partnership, each partner is required to file three returns, a total of nine returns.

Please refer to the Canada Revenue Agency’s technical guidance in the Underused Housing Tax Notice UHTN1 for detailed definitions of what qualifies as a residential property, and who is considered an owner, excluded owner or affected owner.


Significant penalties apply for failure to file a return, even if an exemption applies and no taxes are owing.

Penalties start at $5,000 for affected owners who are individuals, or $10,000 for affected owners that are not individuals (such as corporations).

There is also no limit for CRA to assess the penalties and interest with respect to the property for the calendar year.
