Navigating GST on real estate in Canada can be one of the more complex tax challenges that buyers, investors, and landlords face. Whether you are purchasing a brand-new condominium in Calgary, assigning a preconstruction contract, or renting out a basement suite, the GST rules differ significantly depending on the transaction type. This guide breaks down the 2025 rules clearly so you can make informed decisions and avoid costly surprises.
When you purchase a newly constructed or substantially renovated home in Canada, the federal Goods and Services Tax applies at the standard rate of 5% on the purchase price. This applies whether the buyer is an individual purchasing a primary residence, a second home buyer, or an investor. The GST obligation exists regardless of the buyer's purpose.
Builders typically handle the GST in one of two ways: either they include it within the advertised purchase price, or they show it as a separate line item on the agreement of purchase and sale. Either way, buyers should confirm how GST is treated in any new home contract before signing.
This tax applies equally to all forms of new residential construction, including detached homes, newly constructed condominiums, and townhouses. It also applies when a property has been substantially renovated, meaning it has undergone renovations so extensive that the CRA considers it equivalent to a new build.
To offset the burden of GST on qualifying new homes, the federal government provides the GST New Housing Rebate. The availability and amount of this rebate depends on the fair market value of the property at the time of purchase.
To qualify for the rebate, the property must be purchased as the buyer's primary place of residence, or as the primary residence of a close relation. Investment properties and secondary homes do not qualify. Buyers must apply for the rebate within two years of the closing date.
In practice, most builders credit the rebate amount directly at closing. In exchange, the buyer assigns their right to the rebate to the builder, who then claims it from the CRA. This arrangement simplifies the process for buyers but requires careful review to ensure the rebate has actually been applied and calculated correctly.
It is worth noting that many provinces, including Ontario and British Columbia, have their own provincial new housing rebates that may stack with the federal rebate. Alberta has no provincial sales tax, so Calgary buyers deal only with the federal GST component.
One of the most straightforward rules in Canadian real estate tax law is that the resale of a previously owned residential property between individual buyers and sellers is exempt from GST. If you are purchasing a used single-family home, townhouse, or condominium from an individual vendor who used it as a place of residence, no GST applies to the transaction.
This exemption is why the vast majority of real estate transactions in Canada — the typical MLS resales between homeowners — proceed without any GST consideration.
There is an important exception to this exemption. If a property has been substantially renovated, the CRA treats it as equivalent to a newly constructed home, and GST applies on the sale. The CRA defines substantial renovation as the removal and replacement of 90% or more of the interior of the building. Cosmetic updates, partial renovations, or even major kitchen and bathroom remodels typically do not meet this threshold. However, a full gut renovation almost certainly will, and sellers in this situation must collect and remit GST accordingly.
Assignment sales have become a heavily scrutinised area of Canadian real estate taxation. An assignment sale occurs when the original purchaser of a preconstruction unit sells their agreement of purchase and sale to a new buyer before the builder completes and transfers the unit.
Since January 13, 2023, all assignment sales of preconstruction residential properties are fully taxable at 5% GST. This applies regardless of whether the assignor is a professional builder or an individual investor who simply bought a single preconstruction unit. There are no exceptions based on the seller's intent or registration status.
The assignor is responsible for collecting and remitting GST on the proceeds of the assignment. Depending on how the transaction is structured, GST may apply to the assignment fee alone or to the full purchase price proceeds. The CRA scrutinises these transactions heavily, and many individual assignors have faced unexpected tax bills after failing to register for GST, collect the tax, or remit it properly.
If you are involved in an assignment sale — either as an assignor or an assignee — consulting with a qualified accounting professional before closing is essential. The team at Swift Accounting in Calgary works with real estate investors across Canada and can help you understand your obligations under these rules before they become a problem.
Long-term residential rentals are exempt from GST. If you are a landlord renting a property under a lease or tenancy agreement for 30 days or more, you do not charge GST on the monthly rent. As a consequence of this exemption, landlords also cannot claim Input Tax Credits (ITCs) on expenses related to the exempt rental activity.
Short-term rentals — defined as accommodation provided for periods of less than 30 consecutive days — are treated differently. If you operate a short-term rental through platforms such as Airbnb or VRBO and your annual revenues from these and other commercial activities exceed $30,000, you are required to register for GST, collect it from guests, and remit it to the CRA.
Canadian governments have also been moving to impose GST obligations directly on short-term rental platforms, shifting some compliance responsibility to the platforms themselves. Operators should monitor CRA guidance closely as this area continues to evolve. If you are unsure whether your short-term rental activity triggers GST registration, a conversation with a knowledgeable accountant will save you significant risk.
Builders who construct new residential complexes need to be aware of the self-supply rule. Under this rule, if a builder constructs a new residential property and, instead of selling it, decides to rent it out or use it personally, the CRA deems the builder to have sold and immediately repurchased the property at its fair market value on the date of first occupancy.
This means the builder must self-assess and remit GST on the fair market value of the property — even though no actual sale has taken place. Failing to apply this rule is a common and expensive mistake for developers and small builders who pivot from selling to renting.
The good news is that builders in this situation may qualify for the New Residential Rental Property Rebate (NRRPR), which can partially recover the GST remitted under the self-supply rule. The rebate applies where the units will be used for long-term residential rentals and certain other conditions are met. Proper documentation of fair market value and timely rebate applications are critical.
Swift Accounting Calgary has helped builders and developers navigate self-supply assessments and NRRPR applications, ensuring the correct amounts are remitted and recoverable rebates are not left on the table.
Whether you are a first-time new home buyer trying to understand your rebate, a real estate investor navigating assignment sales, or a builder managing self-supply obligations, the GST rules around Canadian real estate are detailed and unforgiving. Mistakes can result in CRA assessments, penalties, and interest that far exceed the cost of proper advice upfront.

Generally, no. The purchase of a used residential property from an individual who used it as a place of residence is exempt from GST. However, if the property was substantially renovated — meaning 90% or more of the interior was removed and replaced — the CRA treats it as a new home and GST applies at 5%.
If you purchase a new home as your primary residence and the fair market value is under $350,000, you may claim a rebate equal to 36% of the GST paid, up to a maximum of $6,300. For homes priced between $350,000 and $450,000, a partial rebate is available that phases out to zero at $450,000. Homes over $450,000 do not qualify for any federal rebate. The rebate must be applied for within two years of closing, and most builders credit it directly at the time of purchase.
Yes. Since January 13, 2023, all assignment sales of preconstruction residential properties are subject to 5% GST, regardless of whether the assignor is a developer or an individual investor. The assignor must collect and remit GST on the proceeds. The CRA actively audits these transactions, so professional advice before closing an assignment is strongly recommended.
No. Long-term residential rentals — defined as leases or tenancies for 30 or more consecutive days — are exempt from GST. Landlords do not charge GST on monthly rent and cannot claim ITCs on related expenses. Short-term rentals under 30 days, such as Airbnb properties, are taxable if the operator's revenues exceed the $30,000 registration threshold.
