Many Airbnb hosts in Canada may not realize that their rental activities could already be crossing a critical tax threshold.
A recent Canadian tax court case highlights this risk. An Ottawa condominium owner initially rented their unit on a long-term basis, but later transitioned to short-term rentals through Airbnb. The income appeared reasonable—approximately $10,000 in 2017 and over $40,000 in 2018—seemingly consistent with a typical side income strategy.
However, the issue arose when the property was sold.
The owner considered the unit to be their principal residence. The Canada Revenue Agency (CRA), however, took a different view. The property was deemed to be used for commercial purposes, and the owner was assessed 13% Harmonized Sales Tax (HST) on the full sale price—not just on the profit. This resulted in a tax liability of over $77,000.
Why Did This Happen?
Under Canadian tax principles, a property may be classified as a commercial operation if it is used in a manner similar to a business. This can include situations where the property is:
- Frequently rented on a short-term basis (e.g., Airbnb, VRBO)
- Leased by the day or week
- Operated with services or inclusions comparable to a hotel (e.g., utilities, furnished accommodations)
When these conditions are met, the CRA may determine that the property is not a residential asset, but rather a commercial one. As a result, the sale of the property may be subject to HST.
Is Occasional Short-Term Rental Safe?
A common question is whether occasional or limited short-term rental activity can avoid this classification. Unfortunately, Canadian tax law does not provide a clear threshold or “safe harbour.”
While some practitioners suggest that properties used predominantly (e.g., close to 90%) for short-term rentals are at higher risk, even a period of intensive short-term rental activity may be sufficient for the CRA to classify the use as commercial. Ultimately, the determination is fact-specific and subject to CRA interpretation.
The Overlooked Risk: Change in Use
Another important consideration is the concept of “change in use.” When a principal residence is converted into a short-term rental property, the CRA may deem that the use of the property has changed from personal to income-producing.
This can trigger several tax consequences:
- Deemed disposition, potentially resulting in capital gains tax
- Loss of eligibility for the principal residence exemption
- Increased exposure to HST upon sale
HST and the Hidden Cost to Sellers
In many real estate transactions, sale prices are negotiated without explicitly addressing HST. However, the CRA may treat the agreed-upon price as tax-inclusive. In practical terms, this means that if HST applies, the seller may be required to remit the tax out of the proceeds—effectively reducing their net return.
Practical Considerations for Property Owners
If you are currently operating a short-term rental or considering selling a property that has been used in this manner, it is important to take a proactive approach:
- Maintain detailed records of rental activity
- Clearly distinguish between short-term and long-term use
- Seek advice from a qualified accountant or tax professional
- Conduct tax planning before listing or selling the property
Final Thoughts
What many property owners view as a supplemental source of income may, from a tax perspective, already constitute a commercial operation. Understanding how your property use is classified is essential to avoiding unexpected tax liabilities.
