This article reflects the First-Time Home Buyers’ (FTHB) GST/HST Rebate as confirmed on canada.ca following Bill C-4’s Royal Assent on March 12, 2026.
If you’re a first-time buyer considering a newly built home over a resale, there’s now a federal tax measure that can meaningfully change the math: a rebate that eliminates up to 100% of the GST on a qualifying new home, worth as much as $50,000. It sounds like a straightforward win, and for many buyers it is — but the eligibility rules include a few strict conditions that have already disqualified real buyers who assumed they’d qualify. Understanding those conditions before you sign a purchase agreement matters just as much as knowing the rebate exists.
What This Rebate Actually Is
The First-Time Home Buyers’ GST/HST Rebate (FTHB rebate) is a federal measure that eliminates the GST — or the federal portion of the HST in provinces that use it — on qualifying newly constructed homes. It became law when Bill C-4 received Royal Assent on March 12, 2026, and it applies to purchase agreements signed with a builder on or after March 20, 2025, and before 2031, provided construction is substantially completed before 2036.
This is a top-up to the existing GST/HST New Housing Rebate that’s applied for decades — it doesn’t replace it, it adds to it for buyers who qualify as first-time buyers specifically.
How Much You Could Actually Save
The rebate works on a tiered scale based on the home’s price:
- $1 million or less: You recover 100% of the GST paid, up to the full $50,000 maximum.
- Between $1 million and $1.5 million: The rebate phases out on a straight-line basis. A home priced at $1.25 million — the midpoint of that range — qualifies for 50% of the maximum, or $25,000.
- $1.5 million or above: No rebate under this program.
To put a concrete number on it: a $900,000 newly built home would normally carry $45,000 in federal GST. Under this rebate, that entire amount is eliminated.
The “First-Time Buyer” Definition — Where People Get Tripped Up
This is the part worth reading carefully, because the definition is stricter than many buyers assume. To qualify as a first-time buyer, you generally need to meet all of the following:
- Be at least 18 years old
- Be a Canadian citizen or permanent resident
- Not have lived in a home that you or your spouse or common-law partner owned — anywhere in the world — as a primary residence, during the current calendar year or the four preceding calendar years
- Not have previously received this specific FTHB GST/HST rebate (this is a one-time claim per individual)
The detail that surprises the most buyers is the spousal condition. Even if you personally have never owned a home, you can be disqualified if your spouse or common-law partner owned and lived in one during that same window — regardless of whether you were part of that household at the time. This means two people who are both individually first-time buyers on paper can still run into eligibility problems once their combined history is considered.
Other Conditions That Must Be Met
Beyond the buyer’s personal eligibility, the home itself and the transaction need to meet specific conditions:
- The home must be newly constructed or substantially renovated — resale homes don’t qualify under this rebate
- You must be purchasing the home as your primary place of residence
- You (or another eligible purchaser on the same purchase) must be the first person to occupy the home after substantial completion
- The purchase agreement must have been signed with the builder on or after March 20, 2025
A Practical Note on Down Payments
The rebate doesn’t reduce how much down payment you need upfront. Your down payment is calculated based on the home’s pre-tax purchase price, so that requirement doesn’t change regardless of the rebate. It’s also worth knowing that because the rebate isn’t guaranteed until the CRA actually approves your application, mortgage lenders generally won’t count an unreceived rebate as verified funds for down payment purposes — so don’t plan your closing budget assuming the rebate will arrive in time to cover part of your down payment.
How the Rebate Is Actually Paid
There are two common paths:
- Builder credit at closing: Some builders will apply the rebate directly, reducing what you owe at closing. This is the simplest path if your builder offers it.
- Direct CRA application: If your builder didn’t credit the rebate, or if you took possession before the law’s Royal Assent, you can apply directly to the CRA for the rebate after closing.
If you’re unsure which path applies to your purchase, ask your builder directly whether they’re crediting the FTHB rebate at closing or expecting you to apply separately.
What NOT to Do
- Don’t assume you qualify as a first-time buyer just because you personally have never owned a home — check your spouse or common-law partner’s ownership history for the same period too
- Don’t apply this rebate expectation toward your down payment savings plan — lenders won’t count an unapproved rebate as verified funds
- Don’t assume a resale home qualifies — this rebate applies specifically to new builds, owner-built homes, and certain co-op shares
- Don’t skip confirming with your builder whether the rebate will be credited at closing or needs to be claimed separately afterward
- Don’t rely on provincial rebate figures (such as Ontario’s proposed enhanced HST rebate) as guaranteed savings until you’ve confirmed the specific provincial measure has actually passed into law, since proposed provincial programs can differ from what’s already confirmed federally
The Bottom Line
For a first-time buyer purchasing a newly built home priced at or under $1 million, this rebate can eliminate the entire GST bill — a real, meaningful difference in total cost. But the eligibility conditions, especially the spousal ownership-history rule and the new-build-only restriction, disqualify more buyers than the “up to $50,000” headline suggests. Before you factor this rebate into your budget, it’s worth confirming your specific eligibility — including your spouse or partner’s housing history — rather than assuming it applies simply because you’ve never personally owned a home.
FAQ Section
I’ve never owned a home, but my spouse has — do I still qualify? Generally, no. The eligibility rule considers whether you or your spouse/common-law partner owned and lived in a home as a primary residence during the current year or the four preceding years. If your spouse meets that condition, it can disqualify the household even if you personally have never owned property.
Does this rebate apply to resale homes? No. It applies specifically to newly constructed homes, substantially renovated homes, certain owner-built homes, and eligible co-operative housing shares — not resale purchases.
Can I use the expected rebate amount toward my down payment? No. Your down payment is calculated on the home’s pre-tax price regardless of the rebate, and since the rebate isn’t guaranteed until CRA approval, lenders won’t treat it as verified down payment funds.
How do I actually receive the rebate — is it automatic? It depends on your builder. Some builders credit the rebate directly at closing, reducing the amount you owe. If yours doesn’t, or if you took possession before the law’s March 12, 2026 Royal Assent, you can apply directly to the CRA afterward.
