GST Rebate on New Homes 2026: First-Time Buyer Rules

Imagine you and your partner are finally ready to buy your first home together — a brand-new townhouse priced at $850,000. There’s just one catch: your spouse owned a condo five years ago, before you even met. Does that disqualify you from the GST rebate first time home buyer Canada program? This question keeps thousands of couples up at night, and the answer changed significantly when Bill C-4 received Royal Assent on March 12, 2026. In this guide, you’ll learn exactly who qualifies for the enhanced GST rebate, how the new $1 million threshold works, what happens when one spouse previously owned property, and — critically — how a brand-new Ontario provincial rebate stacks on top of the federal savings.

Quick Answer:

• As of March 12, 2026 (Bill C-4’s Royal Assent), first-time buyers can claim a 100% GST rebate (federal portion) on new homes valued up to $1 million — potentially saving up to $50,000, and this applies retroactively to agreements entered into on or after May 27, 2025
• If your spouse owned a home before your relationship began but hasn’t owned or lived in a home (that they or you owned) within the current calendar year plus the four preceding calendar years, you may still qualify — but a relationship breakdown alone is not grounds for eligibility if a spouse previously claimed the rebate
• For homes between $1 million and $1.5 million, a partial rebate applies on a straight-line basis; homes over $1.5 million receive no federal first-time buyer GST relief
• New for 2026: Ontario introduced its own enhanced provincial rebate covering the full 8% provincial HST portion up to $1.5 million (with a phasing top-up to $1.85 million), stacking on top of the federal rebate for agreements signed between April 1, 2026 and March 31, 2027
• You can apply through your builder at closing or directly to the CRA within two years of purchase

What Is the GST Rebate First Time Home Buyer Canada Program in 2026?

The GST rebate first time home buyer Canada program is a federal initiative designed to reduce the upfront cost of purchasing a newly built home. When you buy a brand-new house, townhouse, or condo, you pay GST (or the federal portion of HST in provinces like Ontario) on the purchase price. For expensive properties, this tax can add tens of thousands of dollars to your costs.

On March 12, 2026, Bill C-4 (the “Making Life More Affordable for Canadians Act”) received Royal Assent, officially making the First-Time Home Buyers’ GST Rebate law. According to the Department of Finance, qualified first-time buyers purchasing new homes valued up to $1 million now receive a 100% rebate of the GST (or federal HST component) — a change expected to deliver approximately $3.9 billion in tax savings to Canadians over five years.

💡 Important detail many buyers miss: This rebate applies retroactively. If you signed a qualifying purchase agreement on or after May 27, 2025 (even though the law didn’t officially pass until March 2026), you can still claim the rebate. If you closed on an eligible home during this window and paid GST, don’t assume you missed out — you can still apply.

How Much Can You Actually Save?

The math is straightforward but powerful. GST is 5% of your home’s purchase price. On a $900,000 new build, that’s $45,000 in GST. Under the 2026 rules, a qualifying first-time buyer gets all $45,000 back. In HST provinces like Ontario, you’d recover the 5% federal portion first — and as we’ll cover below, a new Ontario-specific rebate can now return much of the remaining 8% provincial portion too.

For context, $45,000 is enough to cover a substantial down payment, fund six years of TFSA contributions at the $7,000 annual limit, or pay your property taxes for nearly a decade in many Canadian cities.

What Changed in March 2026?

Before this rebate, the standard GST/HST new housing rebate had complex phase-out thresholds. The maximum rebate was capped at a few thousand dollars, and it phased out completely for homes over approximately $450,000 — a price point that barely covers a one-bedroom condo in most major Canadian cities.

The new First-Time Home Buyers’ GST/HST Rebate effectively creates a parallel program specifically for first-time buyers. If you qualify, you get the full GST back on homes up to $1 million. Between $1 million and $1.5 million, the rebate decreases on a straight-line basis. Above $1.5 million, you receive no first-time buyer GST relief (though the standard new housing rebate may still apply). The program is legislated to apply to agreements signed before January 1, 2031.

Who Qualifies for the First Time Buyer GST Rebate Eligibility in 2026?

First time buyer GST rebate eligibility depends on several factors, and this is where many Canadians — especially couples — get confused. The CRA’s definition of “first-time buyer” differs slightly from other programs like the First Home Savings Account (FHSA) or the Home Buyers’ Plan.

The Basic Requirements

To qualify for the enhanced rebate, you must meet all of these criteria:

1. You’re buying a new or substantially renovated home. This rebate doesn’t apply to resale homes. The property must be newly constructed or renovated to the point where it’s essentially a new build (at least 90% of the interior removed and replaced).
2. You’re an individual (not a corporation or partnership). The rebate is for personal home purchases, not investment properties bought through a numbered company.
3. You’re at least 18 years old and a Canadian citizen or permanent resident. These baseline eligibility criteria apply to every claimant.
4. You or your spouse/common-law partner will live in the home as your primary residence. This isn’t for rental properties or vacation homes.
5. You haven’t owned and lived in a home in the current or four preceding calendar years. This is the crucial “first-time buyer” test. Specifically, you cannot have lived in a home — in or outside Canada — that you or your spouse/common-law partner owned during the calendar year of purchase or the four preceding calendar years.
6. Your home’s value falls within the eligible range. For the full 100% rebate, the purchase price must be $1 million or less.

The Spouse Ownership Question

Here’s where it gets complicated for couples — and this is one of the most misunderstood aspects of the new home GST rebate 2026 rules.

When you purchase a home with a spouse or common-law partner, both of you must qualify as first-time buyers for the full enhanced rebate. This means neither of you can have lived in a home you or they owned during the current calendar year or the four preceding calendar years.

There’s an important nuance that benefits many couples: the test looks at whether you lived in the home you owned. If your spouse owned an investment property they never lived in, that typically doesn’t disqualify you. Similarly, if your spouse owned a home years ago but has been renting for the past four-plus years, you could both qualify.

⚠️ A critical limit on this flexibility: The legislation explicitly states that the recent breakdown of a marriage or common-law partnership is not, by itself, sufficient grounds to be considered an eligible first-time buyer. In other words, if you or your spouse previously claimed this exact rebate on a home, or if a former partner’s ownership would otherwise disqualify you, simply separating or divorcing doesn’t reset your eligibility. This is a meaningful limitation that wasn’t well understood in early coverage of the program — consult a tax professional if your situation involves a recent separation.

Understanding the timing rules is crucial if you’re planning your home purchase. If your partner sold their previous home more than four years ago, you could both qualify now. This is exactly the kind of planning discussed in our guide on whether there’s a perfect time to buy a home in Canada.

New Home GST Rebate 2026: Comparing Your Rebate Scenarios

The amount you’ll receive depends on your home’s value and whether you meet the first-time buyer criteria. Here’s a comparison table showing what different buyers can expect under the confirmed 2026 rules (federal rebate only):

*The standard GST/HST new housing rebate (for non-first-time buyers) phases out completely for homes over approximately $450,000. Maximum standard rebate is $6,300 federally.

As the table shows, the new home GST rebate 2026 rules create a massive advantage for qualifying first-time buyers. Someone purchasing a $900,000 townhouse who qualifies as a first-time buyer saves $45,000 compared to previous rules, where they might have received zero rebate at that price point. And as covered below, buyers in Ontario can now stack a substantial provincial rebate on top of this.

GST Rebate Married Couples Canada: Special Rules You Need to Know

The GST rebate married couples Canada rules contain several nuances that can make or break your eligibility. Let’s address the scenarios that trip up the most buyers.

When One Spouse Previously Owned Property

If either spouse lived in a home they or you owned within the current calendar year or the four preceding calendar years, neither of you qualifies for the enhanced first-time buyer rebate. However, you may still qualify for the standard GST/HST new housing rebate (though that phases out at much lower home values).

There’s a planning opportunity here. If your spouse sold their home over four years ago and you’re not in a rush, that timing may already work in your favour. If it’s closer to the four-year mark, waiting until it passes could save you $30,000 to $50,000 in GST.

Common-Law Partners and the Definition of Spouse

The CRA considers you common-law partners if you’ve lived together in a conjugal relationship for at least 12 continuous months. Once you’re common-law, the same rules apply — both partners must be first-time buyers for the enhanced rebate.

Some couples mistakenly believe they can have just one person on title to qualify. This doesn’t work. The CRA looks at both you and your spouse/common-law partner, regardless of whose name is on the property title.

What If You’re Separated But Not Divorced?

Be cautious here. The legislation specifically states that a recent relationship breakdown alone does not make you eligible if you would otherwise be disqualified — for example, if your spouse previously claimed this exact rebate. Documentation of a genuine, longer-term separation may matter, but don’t assume separation resets the clock. Consult a tax professional before assuming you qualify in this situation.

How Do You Apply for the First-Time Home Buyer GST Rebate in 2026?

Applying for the rebate is relatively straightforward, though you have two main options depending on your situation.

Option 1: Apply Through Your Builder (Most Common)

Most first-time buyers apply through their builder at the time of purchase. Here’s how it works:

Step 1: When you sign your purchase agreement, tell your builder you’re a first-time buyer and intend to claim the enhanced GST rebate. They’ll include this in your paperwork.

Step 2: Complete Form GST190, GST/HST New Housing Rebate Application for Houses Purchased from a Builder. Your builder typically provides this form and may help you complete it.

Step 3: Sign the rebate assignment portion. This authorizes the builder to receive the rebate on your behalf and credit it toward your purchase price. Instead of paying the full GST and waiting for a refund, the rebate reduces what you owe at closing.

This method is faster and easier because you never actually pay the GST — it’s netted out before closing. Most major builders in Canada are set up to handle this automatically, though builders who closed sales between May 2025 and March 2026 (before the law passed) may not have been able to credit it at closing — if that’s your situation, you’ll need to apply directly to the CRA.

Option 2: Apply Directly to the CRA

If you don’t apply through your builder — or if you’re purchasing a substantially renovated home from a private seller, or you closed during the period before Royal Assent — you can apply directly to the CRA after closing.

Step 1: Pay the full GST/HST at the time of purchase (or confirm what you already paid if you closed before March 2026).

Step 2: Complete Form GST190 within two years of the property’s ownership transfer date. Include all supporting documentation: purchase agreement, proof of occupancy, identification, and evidence of your first-time buyer status.

Step 3: Mail your application to the appropriate CRA tax centre. You can find the address on the form. Processing typically takes 4–8 weeks, though complex or retroactive cases may take longer given the volume of claims following Royal Assent.

Step 4: Receive your rebate as a direct deposit or cheque. Ensure your CRA My Account information is up to date for fastest payment.

What Documents Do You Need?

Whether applying through your builder or directly, gather these documents:

• A copy of your purchase agreement showing the purchase price and GST/HST paid
• Proof that you’ve occupied the home as your primary residence (utility bills, driver’s licence change, etc.)
• Identification for all purchasers (both spouses if applicable), confirming citizenship or permanent residence status
• A signed statement declaring first-time buyer status

What About Provincial HST Rebates in Ontario and Other Provinces?

If you live in a province with HST (Ontario, New Brunswick, Newfoundland and Labrador, Nova Scotia, or Prince Edward Island), there’s both federal and provincial HST on your home. The enhanced first-time buyer rebate covers the federal portion (5%). Here’s the part that changed dramatically for 2026: Ontario has introduced its own enhanced provincial rebate that stacks on top.

Ontario’s New Enhanced Provincial Rebate (2026)

On October 28, 2025, Ontario announced it would offer a rebate of the full 8% provincial portion of the HST for first-time home buyers on new homes — a dramatic departure from the old rules. Before this change, Ontario’s provincial New Housing Rebate phased out entirely once a home’s price exceeded $450,000, capping at a maximum of $24,000. Because most new homes in the Greater Toronto Area are priced well above $450,000, most buyers received little to no meaningful provincial rebate.

Under the enhanced program, for agreements of purchase and sale signed between April 1, 2026 and March 31, 2027, eligible first-time buyers can recover the full 8% provincial HST on homes up to $1.5 million, with a top-up amount for homes between $1.5 million and $1.85 million that decreases on a straight-line basis to $0.

Revised Example: A $900,000 Home in Ontario

For a $900,000 home in Ontario, a first-time buyer purchasing under the new rules could receive:

• Federal first-time buyer rebate: $45,000 (100% of the 5% federal portion)
• Ontario provincial rebate (new enhanced program): Up to $72,000 (100% of the 8% provincial portion, since $900,000 is under the $1.5 million cap)
• Total HST paid: $117,000 (13% of $900,000)
• Total rebate: Potentially up to $117,000 — effectively eliminating the entire HST

This is dramatically more generous than the federal-only savings previously available. On a full $1 million home closed within the Ontario-eligible window, one accounting analysis calculated a combined rebate of approximately $130,000 — essentially the entire 13% HST eliminated.

💡 Timing matters enormously here. The enhanced Ontario rebate specifically applies to agreements signed between April 1, 2026 and March 31, 2027. If your agreement falls outside this window, confirm current Ontario rules directly, as this is a fast-moving and relatively new program.

British Columbia and Alberta

In BC and Alberta, there’s no provincial sales tax on new homes, so you only pay the 5% GST. This makes the federal first-time buyer rebate particularly valuable on its own — qualifying buyers pay $0 in GST on new homes up to $1 million, with no separate provincial HST layer to navigate.

Common Mistakes That Cost First-Time Buyers Thousands

After reviewing rebate rules and applications, certain errors appear repeatedly. Avoid these costly mistakes.

Mistake #1: Assuming Investment Property Ownership Disqualifies You

The first-time buyer test looks at homes you lived in as your principal residence. If you inherited a rental property and never lived in it, you may still qualify. Always consult a tax professional about your specific situation.

Mistake #2: Assuming a Separation Resets Your Eligibility

As covered above, the legislation specifically states that a relationship breakdown alone isn’t sufficient grounds for eligibility if you’d otherwise be disqualified. Don’t assume separating from a spouse who previously owned or claimed the rebate automatically clears you.

Mistake #3: Missing the Retroactive Application Window

If you closed on an eligible new home between May 27, 2025 and March 12, 2026 (before Royal Assent) and paid the full GST/HST without a builder credit, you may still be able to claim your rebate directly from the CRA. Don’t assume you missed out just because the law wasn’t finalized when you closed.

Mistake #4: Missing the Two-Year Application Deadline

If you don’t apply through your builder at closing, you have only two years from the ownership transfer date to submit your rebate application to the CRA. Miss this deadline, and you forfeit tens of thousands of dollars permanently. Set a calendar reminder immediately after closing.

Mistake #5: Not Coordinating With Your Mortgage Strategy and FHSA

Your GST rebate could affect your mortgage approval and down payment strategy. Some buyers use the expected rebate as part of their calculations (applying through the builder so it’s credited at closing). Others may need to arrange bridge financing if applying to the CRA after closing.

While the GST rebate and FHSA are separate programs, they work together well. The First Home Savings Account allows you to save $8,000 per year (up to $40,000 lifetime) tax-free for a home purchase, with contributions tax-deductible like an RRSP and withdrawals tax-free like a TFSA. Combined with the RRSP Home Buyers’ Plan (up to $60,000 per person), you have significant tax-advantaged tools working alongside your GST savings.

Key Takeaways

• First-time buyers can now claim a 100% GST rebate (up to $50,000) on new homes priced at $1 million or less — Bill C-4 received Royal Assent March 12, 2026, and the rebate applies retroactively to agreements signed on or after May 27, 2025
• Both spouses or common-law partners must meet the first-time buyer test (no lived-in home ownership in the current or four preceding calendar years) for a couple to qualify
• A relationship breakdown alone does not make you eligible if you’d otherwise be disqualified — this is a specific legislative limitation
• Owning an investment property you never lived in typically doesn’t disqualify you — the test focuses on homes you actually occupied
• Ontario buyers get a major bonus: a new provincial rebate covering the full 8% HST up to $1.5 million (for agreements signed April 1, 2026–March 31, 2027) can stack with the federal rebate, potentially eliminating the entire 13% HST
• Apply through your builder at closing for the simplest process; if applying directly to the CRA, submit within two years of ownership transfer
• The program applies to agreements signed before January 1, 2031

Frequently Asked Questions

Can I get the GST rebate if my spouse owned a home before we met?

It depends on timing. If your spouse lived in a home they owned at any point during the current calendar year or the four years before your purchase date, neither of you qualifies for the enhanced first-time buyer GST rebate. However, if your spouse sold their home and hasn’t lived in an owned home for more than four years, you may both qualify. The key is whether they lived in a home they owned within that lookback period — not whether they ever owned property in their lifetime.

What is the GST rebate on a $1.25 million new home in Canada?

For a $1.25 million new home, a first-time buyer receives a partial federal GST rebate of approximately $31,250. The enhanced first-time buyer rebate phases out on a straight-line basis between $1 million and $1.5 million. At $1.25 million, you’re halfway through the phase-out range, so you’d receive roughly 50% of what you’d get on a sub-$1 million home. On homes above $1.5 million, first-time buyers receive no enhanced federal rebate.

How do I apply for the first-time home buyer GST rebate in 2026?

The easiest method is to apply through your builder at closing. You’ll complete Form GST190 and assign the rebate to your builder, who credits it against your purchase price — so you never actually pay the GST. Alternatively, you can pay the full GST at closing and apply directly to the CRA within two years using Form GST190 and supporting documents (purchase agreement, proof of occupancy, identification). If you closed between May 2025 and March 2026, before the law’s Royal Assent, you’ll likely need to apply directly to the CRA since builders couldn’t credit the rebate during that period.

Does the Ontario HST rebate stack with the federal GST rebate in 2026?

Yes — for agreements signed between April 1, 2026 and March 31, 2027, Ontario’s newly enhanced provincial rebate covers the full 8% provincial portion of HST on new homes up to $1.5 million (with a phasing top-up to $1.85 million), stacking on top of the federal 5% rebate. On a $1 million home, this combination can eliminate the entire 13% HST — a total rebate that can reach approximately $130,000, far more than the federal rebate alone.

---

Understanding the GST rebate first time home buyer Canada rules could save you up to $50,000 federally — and potentially far more if you’re buying in Ontario — on your new home purchase in 2026. Whether you’re navigating the spouse ownership question, calculating your expected rebate on a higher-priced home, or deciding when to apply, the key is to verify your eligibility early, understand the retroactive rules, and gather your documentation before closing.
