GST in BC Real Estate: The Fundamentals
Canada's Goods and Services Tax (GST) is a 5% federal consumption tax administered by the Canada Revenue Agency (CRA). In real estate, GST applies selectively — it does not apply to every transaction. Understanding the scope is the first step to advising clients correctly.
What GST Applies To
| Transaction Type | GST Applies? | Notes |
|---|---|---|
| Resale home (used residential) | ❌ No | Exempt supply — no GST on purchase price |
| New home (first sale from builder) | ✅ Yes — 5% | On purchase price; rebate may apply |
| Substantially renovated home | ✅ Yes — 5% | 90%+ interior removed/replaced |
| Pre-sale condo (builder direct) | ✅ Yes — 5% | Usually included in contract price |
| Assignment of pre-sale contract | ⚠️ Conditional | GST on assignment fee if flipper intent |
| Commercial property | ✅ Yes — 5% | Full purchase price; no housing rebate |
| Commercial-to-residential conversion | ✅ Yes — 5% | On fair market value at time of first use |
| Vacant land (for residential use) | ⚠️ Conditional | GST if vendor is a builder or business |
| Farmland | ⚠️ Conditional | Exempt if buyer is farmer; taxable otherwise |
| Realtor commissions | ✅ Yes — 5% | Realtors charge GST on their commission |
Realtor tip:The most common client confusion is assuming GST applies to all property purchases. Clarify early: "If you're buying a resale home, there's no GST on the purchase price. If you're buying from a builder — new or pre-sale — GST applies, though it's often included in the listed price."
GST on New Homes: How It Works
When a builder sells a newly constructed home for the first time, GST at 5% applies to the purchase price. In practice, most builders in BC include GST in their advertised price — but this is not guaranteed. Your client's purchase contract must clearly state whether the price is GST-inclusive or GST-exclusive.
Reading the Contract of Purchase and Sale
BCREA's Contract of Purchase and Sale includes a GST clause specifying whether GST is included or added to the stated price. A client purchasing a $700,000 new home:
- GST included: $700,000 total (builder has already factored in 5%)
- GST extra: $700,000 + $35,000 GST = $735,000 total out of pocket
Never assume. If the CPS is ambiguous, ask the listing agent or builder's representative in writing before your client removes subjects.
GST New Housing Rebate
Buyers of new homes used as a primary residence may qualify for the federal GST New Housing Rebate. The rebate is calculated at 36% of the GST paid, subject to limits:
| Purchase Price (Before GST) | Maximum Rebate | Notes |
|---|---|---|
| $350,000 or less | $6,300 | Full rebate: 36% × $17,500 GST = $6,300 |
| $350,001 – $449,999 | Phases out proportionally | Rebate = $6,300 × (($450,000 − price) / $100,000) |
| $450,000 or more | $0 | No federal rebate available |
Eligibility conditions:
- Purchaser or a relation intends to use the home as primary place of residence
- Builder has not already assigned the rebate to another party
- Purchaser has not previously claimed the rebate on another property
- Application filed within 2 years of closing (Form GST190)
Builder assignment of rebate:In many new home contracts, especially in Metro Vancouver, the builder assigns the rebate to themselves and reduces the purchase price accordingly. The client still benefits from the rebate amount — it's baked into the price — but they cannot claim the rebate again through CRA. Check the contract for "assignment of rebate" language.
Pre-Sale Condos: GST in Practice
Pre-sale condo purchases are a staple of Metro Vancouver, Burnaby, Surrey, and Victoria markets. Several GST rules apply uniquely to pre-sale transactions.
GST Inclusion in Pre-Sale Contracts
Most Metro Vancouver pre-sale disclosure statements (filed under REDMA) state whether the purchase price includes GST. Verify in Section 15 (financial disclosure) of the developer's disclosure statement. If GST is additional, your client's true cost of acquisition increases by 5% at completion.
Timing of GST Payment
Unlike resale completions, pre-sale completions often occur 2-5 years after contract signing. GST is assessed at the time of completion, not at signing. This means:
- The GST rate at signing applies if it hasn't changed
- If the buyer sells their interest (assigns) before completion, different GST rules apply
- If the project is delayed, the GST obligation follows completion, not the original closing date
Using a Pre-Sale as Rental: Rental Rebate
Buyers purchasing a pre-sale condo for long-term rental (not personal use) do not qualify for the GST New Housing Rebate (which requires primary residence intent). Instead, they may qualify for the GST New Residential Rental Property Rebate:
- Rebate equals 36% of GST paid, capped at $6,300 (same as housing rebate)
- Property must be for long-term residential rental (not short-term/Airbnb)
- Filed using Form GST524 within 2 years of first being available for rent
- Buyer must enter into rental agreement before or shortly after completion
Assignment Sales and GST: The High-Risk Area
Assignment sales — where the original pre-sale purchaser transfers their purchase contract to a new buyer before completion — involve some of the most complex and contested GST rules in Canadian real estate law.
CRA's Position on Assignment GST
CRA applies a two-step analysis to assignment sales:
- Was the original purchase made for the purpose of assigning it? If yes, CRA may treat the original purchaser as a builder — making the full assignment price subject to GST.
- What was actually transferred? If the original purchaser did not have builder intent, GST applies only to the assignment profit (the amount received above the original contract price plus deposits paid).
| Scenario | GST Treatment | Practical Implication |
|---|---|---|
| Original buyer intended to live there, then assigns due to life change | GST on profit only (if any) | Assignment fee is taxable; document original intent |
| Original buyer was clearly flipping (multiple pre-sales) | GST on full assignment price | CRA audit risk; total GST liability significant |
| Assignment at a loss (below original price) | No GST on assignment (no profit) | Original deposits already paid; no additional GST |
| Assignment with large profit (hot market) | GST on profit amount | Assignor should collect and remit GST on profit |
Critical advisory: BC introduced mandatory assignment disclosure requirements — all assignment sale contracts must be reported to the BC government (Property Transfer Tax reporting). CRA cross-references PTT assignment data for GST compliance audits. Advise clients completing assignments to obtain a tax opinion from a lawyer or accountant before closing.
What the Assignee (New Buyer) Pays
At completion of the underlying pre-sale, the assignee (who purchased the assignment) pays GST to the original builder on the original purchase price — just as any new home buyer would. They may also qualify for the GST New Housing Rebate if they intend to use the unit as their primary residence. The assignment fee itself (what they paid the assignor) is a separate transaction.
Purpose-Built Rental Housing Rebate (2023)
The federal government's September 2023 announcement fundamentally changed the economics of purpose-built rental construction in Canada. The Purpose-Built Rental Housing Rebate eliminates GST entirely for qualifying rental building projects.
Qualifying Criteria
| Requirement | Details |
|---|---|
| Building type | New construction or substantial renovation; not existing buildings |
| Minimum units | 4 or more residential units |
| Rental commitment | Held for long-term residential rental (not short-term/vacation) |
| Rebate amount | 100% of the 5% GST — full elimination |
| Construction start | After September 14, 2023 (pre-announcement projects phased in) |
| Individual condo investors | ❌ Do NOT qualify — must be purpose-built rental building |
For BC realtors working with development clients or investors, this rebate has significantly improved the feasibility of purpose-built rental projects in Metro Vancouver, Victoria, and Kelowna — cities where land costs previously made rental development economically unviable without subsidy.
Substantially Renovated Homes
A home that has been substantially renovated is treated like a new home for GST purposes — GST applies to the fair market value at the time of first sale. Understanding the threshold is critical because many realtors incorrectly assume extensive renovations trigger GST.
The 90% Rule
CRA requires that 90% or more of the interior of the existing building be removed or replaced. The calculation excludes:
- Foundation
- Exterior walls
- Interior supporting walls
- Floors (structural slab)
- Roof structure
- Staircases
Everything else — electrical, plumbing, HVAC, interior walls, ceilings, insulation, windows — counts toward the 90% threshold.
| Renovation Scope | Substantially Renovated? | GST Applies? |
|---|---|---|
| Full gut renovation: new electrical, plumbing, HVAC, walls, windows | ⚠️ Possibly — depends on % calculation | Consult CRA or tax lawyer |
| Heritage building: full interior gutted, only exterior walls remain | ✅ Yes — classic case | Yes — on fair market value at first sale |
| New kitchen + bathrooms + flooring + paint | ❌ No | No — resale treatment |
| Full basement development in previously unfinished space | ❌ No | No — addition to existing structure |
| Warehouse-to-loft conversion (all new mechanical, partitions) | ✅ Yes — if 90%+ interior replaced | Yes — commercial conversion + substantial reno |
Realtor due diligence:When listing a significantly renovated older home, ask the seller: "Was the entire interior gutted and replaced?" If yes, they should have obtained a legal opinion on whether it qualifies as substantially renovated — because if it does and they didn't collect GST, the CRA may assess them for the unpaid GST.
Vacant Land and GST
Vacant land transactions carry their own GST complexity. The key question is whether the vendor is a "builder" or individual selling personal-use land.
When GST Applies to Vacant Land
| Vendor Type | Buyer Intent | GST Applies? |
|---|---|---|
| Developer/builder | Any | ✅ Yes — always |
| Individual (personal-use land) | Residential construction | ❌ No — exempt |
| Individual (personal-use land) | Investment/commercial | ✅ Yes — taxable |
| Corporation or business entity | Any | ✅ Yes — always |
| Individual selling part of residential lot (severed) | Residential construction | ❌ Usually exempt |
For ALR land, farmland, and rural vacant parcels, GST applicability often turns on the vendor's GST registration status and the intended use. Always have clients with vacant land transactions reviewed by a tax professional before completion.
Realtor Commissions and GST
This is straightforward but sometimes misunderstood: realtors are required to collect and remit 5% GST on their commission income. The GST is paid by the client (seller), not by the realtor from their commission.
Commission GST Example
On a $900,000 resale home with a 2% listing commission:
- Commission: $18,000
- GST on commission: $900
- Total paid by seller: $18,900
New realtors with annual taxable services under $30,000 may not be required to register for GST — but once they exceed this threshold, registration is mandatory. Most active realtors exceed $30,000 quickly and must register, collect, and file GST quarterly or annually.
Common new realtor mistake: Treating commissions as GST-inclusive rather than GST-extra. Your commission is $18,000; the GST of $900 is collected on top and remitted to CRA. If you fail to collect GST, you are personally liable to CRA for the unremitted amount.
GST and New Construction: Practical Timelines
Builder Holding a New Home: Self-Supply Rule
If a builder constructs a new home and instead of selling it, rents it out, CRA applies the "self-supply rule." The builder is deemed to have sold the home to themselves at fair market value — and is assessed GST on that deemed sale, even though no actual sale occurred. This is a significant GST exposure for builder-landlords.
The self-supply GST is due when the home is first rented out or when the builder (or their relation) first occupies the home. The builder may then claim the GST New Residential Rental Property Rebate if qualifying for long-term rental.
Completion vs. Possession
In BC, new home completions sometimes involve early possession (buyer moves in before title transfer). For GST purposes:
- GST is due at the earlier of: the date title transfers or the date possession is given
- Pre-sale buyers should have funds (including GST amount) available at possession, not just at title transfer
- Builders cannot waive or delay GST collection — it is a statutory obligation
4 Client Advisory Scripts
Script 1: Resale Buyer — No GST
"Good news for your budget: because you're purchasing a resale home, there's no GST on the purchase price. GST only applies to new construction or homes that have been substantially gutted and rebuilt from the inside out. You'll pay GST on my commission — that's standard — but the $850,000 purchase price is GST-free."
Script 2: New Home Buyer — GST Rebate Eligible
"The builder has quoted $480,000 including GST, which means GST is already factored in. Because the pre-GST price is effectively around $457,000, you're above the $450,000 threshold — so unfortunately no federal GST rebate applies. But if your budget allows you to look at projects under $450,000, the rebate of up to $6,300 can meaningfully offset your closing costs. Let me know if you want to see some options in that price range."
Script 3: Pre-Sale Assignment Seller
"Before we list this assignment, I need to flag something important. If you're selling your pre-sale contract at a profit, CRA considers the assignment fee taxable — meaning you may owe GST on that profit. In some cases, if CRA determines you bought the pre-sale intending to flip it, they can assess GST on the full assignment price, not just the profit. I can help you sell the assignment, but I strongly recommend you speak with a tax lawyer before we close — the GST exposure could be significant."
Script 4: Investor Buying Pre-Sale for Rental
"Since you're buying this pre-sale to rent it out long term, the regular GST New Housing Rebate doesn't apply — that one requires you to live in the unit. However, you may qualify for the GST New Residential Rental Property Rebate, which gives you back 36% of the GST you paid, up to $6,300. You'd need to have it rented out as a primary residence for your tenant — no short-term rentals like Airbnb. Worth discussing with your accountant before completion so you file the rebate application on time."
Common GST Mistakes in BC Real Estate
| Mistake | Impact | Prevention |
|---|---|---|
| Assuming all property purchases include GST | Client surprise on resale transactions | Clarify GST status for every transaction type upfront |
| Not verifying whether new home price includes GST | Client underfunds completion | Read GST clause in CPS before removing subjects |
| Advising assignment sellers no GST applies | Unexpected CRA assessment post-closing | Always refer to tax professional for assignments |
| New realtor not registering for GST when over $30K | CRA liability for unremitted GST | Register when approaching threshold; file quarterly |
| Missing 2-year deadline for housing rebate application | Client loses up to $6,300 rebate | Add rebate application deadline to closing checklist |
| Telling rental investors they qualify for the purpose-built rebate | False expectation; rebate for buildings not individual units | Clarify the purpose-built rebate requires 4+ unit buildings |
GST Due Diligence Checklist for BC Realtors
- Is this a new home or resale? New = GST applies. Resale = no GST on purchase price.
- Does the purchase price include or exclude GST? Read the contract and builder's disclosure statement.
- Is the buyer's intended use primary residence or rental? Determines which rebate applies (housing rebate vs. rental property rebate).
- Is the purchase price under $450,000 (pre-GST)? Below $350,000 = full $6,300 rebate; $350K–$450K = partial rebate; above $450K = no rebate.
- Is this an assignment sale? If yes, is the assignor collecting GST on the assignment fee? Tax lawyer required.
- Has the seller substantially renovated the property? If yes, get a legal opinion on whether GST was properly collected.
- Is vacant land involved? Is the vendor a builder or individual? Is the buyer using it for residential or commercial purposes?
- Are you (the realtor) registered for GST? If your annual commission income exceeds $30,000, registration is mandatory.
- Has the rebate application deadline been calendared? GST rebate applications must be filed within 2 years of closing.
