Real estate and property carry some of the most situation-specific tax rules in the Canadian system. Whether a sale is taxable for GST/HST, whether you have to file an Underused Housing Tax return, how a rental property is taxed, and how much of a gain the principal residence exemption can shelter all depend on details that are easy to get wrong. RN Canada Accounting and Advisory works with property owners, landlords, builders and real estate businesses across Alberta and British Columbia — from our Edmonton head office and Vancouver second office, and serving Calgary clients remotely — to get these calls right before a transaction closes, not after.
The accounting pain points unique to real estate
Property is where general tax assumptions break down. The same word — "sale" — can mean a taxable supply or an exempt one depending on whether the property is new, used or commercial. Rental properties have their own net-income rules and a specific limit on depreciation. And a single missed filing, like the Underused Housing Tax return, can carry consequences even when no tax is owed. The work that matters is identifying which rule applies to your specific property and transaction, and keeping records clean enough to support it.
Tax considerations: UHT, GST/HST and rental income
Underused Housing Tax
The Underused Housing Tax (UHT) was a 1% annual tax that applied for the 2022, 2023 and 2024 calendar years. For those years, an affected owner — as opposed to an excluded owner — had to file a UHT return for each residential property they owned on December 31, with the return due April 30 of the following year. The UHT has been eliminated for 2025 and later — no tax and no return going forward. Penalties for the 2022 to 2024 years remain, so a past filing obligation (for example, where property was held through a corporation, partnership or trust) should still be checked even though nothing is required for 2025 onward.

GST/HST on real property
GST/HST treatment turns on what is being sold. New or substantially renovated residential housing is generally taxable; a used, previously occupied residential resale is generally exempt; and commercial real property is generally taxable. A builder selling a new home and an owner reselling a used home are treated very differently, so the treatment should be confirmed before a deal closes.

Rental income and CCA
Rental income is taxed on a net basis — gross rent minus deductible expenses. You may claim Capital Cost Allowance (CCA) on the building, but CCA on a rental property cannot create or increase a rental loss. That limit catches landlords who expect depreciation to generate a loss for the year. Source: T4036, Rental Income — Canada.ca.
The principal residence exemption
The principal residence exemption can shelter the capital gain for the years a property was your principal residence — a major factor when a home has been part-rented, used for business, or owned across a move. The designation and calculation are detail-driven and worth getting right. Source: Principal residence and other real estate — Canada.ca.
The fractional-CFO angle: portfolios and structure
As a property business grows from one rental to a portfolio, the questions move from filing to strategy: How should new acquisitions be held? What is the after-tax return once CCA, GST/HST and financing are modelled? When does a hobby-landlord become a business that needs corporate structure? A fractional CFO brings that senior view part-time. Underneath it, our bookkeeping & tax filing service keeps rent, expenses and CCA tracked cleanly across every property.

Frequently asked questions
Not for 2025 onward — the Underused Housing Tax has been eliminated for the 2025 and later calendar years, with no tax and no return. The UHT was a 1% annual tax that applied for the 2022, 2023 and 2024 calendar years, when an affected owner had to file a UHT return for each residential property they owned on December 31, due April 30 of the following year. Penalties for those 2022 to 2024 years still stand, so if you owned residential property through a corporation, partnership or trust in any of those years, the past filing obligation should still be checked even though no return is required going forward.
It depends on the property. New or substantially renovated residential housing is generally taxable for GST/HST, while a used, previously occupied residential resale is generally exempt. Commercial real property is generally taxable. So a builder selling a new home and an owner reselling a used home are treated very differently, and the line between renovation and substantial renovation matters. We confirm the treatment before a transaction closes rather than after.
Rental income is taxed on a net basis: your gross rent minus your deductible expenses. You may claim Capital Cost Allowance on the building, but CCA on rental property cannot be used to create or increase a rental loss. That limit surprises a lot of landlords who expect depreciation to generate a loss. Keeping clean records of rent and deductible expenses, and applying CCA correctly, is the core of getting rental tax right.
