How GST/HST Could Surprise You: Real Estate Tax Tips Every Ontarian Should Know
When buying or selling real estate in Canada, the price tag isn’t always the full story. In many cases, GST/HST on real estate may apply, and the rules for when and why are anything but straightforward. Whether you’re a homeowner, investor, or entering into short-term rentals, arming yourself with the right real estate tax tips before you sign on the dotted line can help you avoid costly surprises down the line.
Let’s break down what you need to know about GST/HST on real estate, especially if you’re navigating the housing market in Ontario.
When Does GST/HST Apply to Real Estate Transactions?
Here’s the good news: most resale residential properties are exempt from GST/HST. But don’t let that lull you into thinking taxes aren’t an issue. Certain property types and uses trigger tax liabilities that can be significant. These include:
- Newly constructed or substantially renovated homes
New builds and homes with extensive renovations (90% or more interior work) typically incur GST/HST charges. Unless otherwise specified, the seller adds the tax to the sale price; therefore, your agreement must clarify whether GST/HST is included.
- Pre-construction condos and homes
Usually, sellers include GST/HST in the sale price, but verifying this in the purchase agreement is important. First-time homebuyer rebates may apply, but they don’t eliminate the tax.
- Short-term rental properties
If you’re converting your long-term rental into a short-term rental (such as Airbnb), you’re considered using the property for commercial purposes. This use change can trigger GST/HST liabilities even if you originally bought the home as a residential investment.
Real Estate Tax Tips: Avoiding Costly Surprises
Let’s break down a few practical real estate tax tips that could save you thousands—especially in a city like Toronto where pre-construction condos and short-term rentals are common.
Case Study: When a Condo Becomes a Hotel
A recent court case (1351231 Ontario Inc. v. The King) brought these rules into sharp focus. Two brothers owned a condo in Ottawa, renting it to long-term tenants for nearly a decade. However, in the final year before selling, they switched to short-term rentals through Airbnb. CRA later assessed them for $77,000 in GST/HST on the sale.
Why? Under the tax law treats short-term rentals (stays under 60 days) are treated like hotel accommodations. That made the property not a “residential complex” anymore, making the sale subject to GST/HST.
This case is a strong example of how a shift in how you use a property, even a small one, results in major tax consequences.
Key Triggers That Can Lead to GST/HST Owing
Even if you don’t think your property falls under taxable rules, here are common situations that might result in unexpected GST/HST:
- You’re buying a substantially renovated property (90 %+ interior redone)
- You’re selling a property that was used as a short-term rental
- You’re converting from residential to commercial use or vice versa
- You’re buying a new home, and the agreement doesn’t state that GST/HST is included
How GST/HST Affects Your Mortgage Plans
If GST/HST applies, it can increase your upfront costs or reduce your net proceeds if you’re the seller. For buyers, this might mean needing a larger mortgage or additional savings. For sellers, it may mean setting aside funds to cover tax owed to the CRA.
That’s why, when you’re exploring mortgage options, especially for new builds or investment properties, it’s important to work with experts who understand not just the financing, but the tax implications as well.
