GST & Real Estate: Explained

If you are buying real estate in Whistler, there is a good chance you will hear the word "GST" and feel a knot form in your stomach.
You are not alone.
GST on Whistler property is genuinely more nuanced than in most Canadian markets, and getting it wrong before your completion date can be costly.
This guide breaks it all down in plain language so you can walk into your purchase with clarity.
What Is GST, and When Does It Apply?
GST is Canada's Goods and Services Tax, currently set at 5%.
In real estate, it generally applies to new construction and to properties that have been “used commercially”, which includes properties that have been earning revenues from short term nightly rentals (aka AirBnB).
Used residential properties are typically GST-exempt.
That is the simple version.
Whistler, however, adds a layer of complexity because many properties here carry a Phase 1 rental covenant, which means they can be used residentially or commercially, or a Phase 2 rental covenant (commercial use).
Why Is Whistler Different?
Because the same suite can be sold as either GST-exempt (used residential) or GST-applicable (used commercial), depending entirely on how the current owner has been operating and reporting it.
This is what makes Whistler murkier than a straightforward Vancouver condo purchase.
The key question is: how has the seller been using the property?
If the seller's property is being sold as used commercial (and therefore GST-applicable on sale) if either of the following is true:
They earned $30,000 or more in gross short-term rental revenue in any 12-month period, or
They registered for a GST number and filed GST returns or claimed input tax credits.
If neither applies, the property is typically sold as used residential and GST does not apply to the purchase price.
Your 2 Options as a Buyer
If the property you are purchasing has been used commercially, you will need to make a decision before your completion date. The seller's lawyer will ask for either your GST Business Number or your GST payment in order to close the transaction. There is no middle ground at this stage.
Option 1 — Defer the GST: Register for a GST Business Number with the CRA before closing (which is mandatory to receive a Business Licence in order to actually do nightly rentals) and continue operating the property for short-term rentals. You pay little or nothing upfront and file GST returns annually.
Option 2 — Pay GST Upfront Pay the full 5% at closing, convert the property to residential use, and avoid ongoing annual GST filings altogether. A simpler path if you plan to use the property primarily for personal enjoyment.
If You Defer: Here’s How the Annual Calculations Work
Choosing to defer means you will file a GST return each year and true up your deferral based on your actual use of the property that year.
The CRA looks at commercial nights versus personal use nights - and importantly, **vacant days do not count as commercial use**.
This changed in 2007 when the CRA clarified that simply having a property available for rent is not the same as it being in commercial use.
The formula is:
Personal Use % = Personal Use Days ÷ (Rental Nights + Personal Use Days)
Here is how the thresholds break down:
| Commercial Use | Personal Use | GST Outcome | Status |
|---|---|---|---|
| Over 90% | Under 10% | Full deferral — you owe nothing for the year | Full deferral |
| 80% | 20% | Repay 20% of deferred GST for that year (one-time adjustment) | Partial remittance |
| 70% | 30% | Repay approximately 60% of the deferred GST | Partial remittance |
| Under 50% | Over 50% | Repay 100% of deferred GST — property treated as residential | Full remittance |
There is also an important wrinkle: the GST is calculated on whichever is higher — your purchase price or the BC assessed value at the relevant time.
If your assessed value rises between years, your remittance could increase accordingly.
A simple example
Suppose the GST on your purchase works out to $10,000.
Year 1: You intend less than 20% personal use — defer 100%, pay $0
Year 2 actuals: 20% personal use (80% rented) — remit approximately $4,000 (40%)
Year 3 actuals: 10% personal use — recover prior remittance, get approximately $4,000 back
If assessed value rose in Year 2, your 40% is applied to the higher value
What About GST on Nightly Operations?
Yes, nightly rental stays are also subject to GST. If you hold a GST number, your property manager can collect and remit GST under your number, and you may be able to claim input tax credits for related expenses. If you chose to pay GST upfront at closing and are not registered, the manager can remit under their own number — you do not need to file anything.
What If You Change Your Mind Later?
It is possible. If you paid GST upfront and later decide to register and operate commercially, you may be eligible for partial refunds depending on your use in those years — but you will also enter the annual filing and true-up system going forward. Your choice today also affects how the next buyer approaches the purchase, so it is worth thinking ahead.
What About Non-Residents of Canada?
Non-residency does not change the GST framework described above, but it can add additional tax and withholding considerations. Please coordinate with your accountant and reach out to us — we are happy to walk through your specific situation.
So How Do Most Buyers Decide?
There is no universally right answer, but here is how we tend to see it play out in practice:
Pay upfront: If you expect to use the property yourself for 20–50% of the time, or if you simply value simplicity and want to avoid annual filings and assessed-value surprises, many buyers choose to pay the 5% at closing and move on.
Defer and file annually: If you expect low personal use, steady rental income, and are comfortable maintaining a GST number and annual filings, deferring can be a smart cash-flow decision.
| Your Situation | Likely Best Path | Why |
|---|---|---|
| Expect 20–50%+ personal use | Pay GST upfront | Simplicity, no annual filings, no assessed-value surprises |
| Expect low personal use, steady rentals | Defer with GST number | Better cash flow at closing, true-up annually |
| Unsure of your use pattern | Speak to your accountant first | Your specific numbers will point to the right answer |
