Canada's First-Time Home Buyer GST Rebate: How to Save Up to $50,000 on a New Home (2026 Guide)

Last verified: May 11, 2026 — Reflecting Bill C-4 Royal Assent on March 12, 2026 and the 2026 Ontario Budget (March 26, 2026)

---

When Bill C-4 received Royal Assent on March 12, 2026, Canada quietly delivered one of the most consequential pieces of housing policy in recent memory. For a narrow slice of buyers—first-time purchasers of newly built homes—the federal government is now refunding up to $50,000 in GST.

That's not a typo. And it's not a future promise. As of March 12, 2026, the First-Time Home Buyers' (FTHB) GST/HST Rebate is law.

But here's what the headlines miss: the rules are surprisingly strict, the spousal trap disqualifies more buyers than you'd think, and a single date on a presale contract can wipe out your eligibility entirely. Before you build this rebate into your purchase budget, you need to understand exactly what qualifies—and what doesn't.

This guide walks through who qualifies, how much you can actually save, how to claim it, and the fine-print pitfalls that have already cost real buyers their rebate.

How Much Can You Actually Save?

The federal GST is 5%. On qualifying new homes, this rebate can refund all of it—up to a $50,000 cap. The savings work in three tiers based on the home's price:

Home Price	5% Federal GST	Rebate %	Rebate Amount	GST You Actually Pay
$500,000	$25,000	100%	$25,000	$0
$850,000	$42,500	100%	$42,500	$0
$1,000,000	$50,000	100%	$50,000	$0
$1,100,000	$55,000	80%	$40,000	$15,000
$1,250,000	$62,500	50%	$25,000	$37,500
$1,400,000	$70,000	20%	$10,000	$60,000
$1,500,000	$75,000	0%	$0	$75,000

The three thresholds in plain English

• At or below $1 million: You get 100% of the federal GST back (max $50,000).

• Between $1 million and $1.5 million: The rebate phases out linearly. Every $100,000 over $1 million cuts the rebate by 20%.

• At or above $1.5 million: No FTHB rebate. You may still qualify for the older, much smaller standard GST/HST New Housing Rebate, but that's a separate program.

The math is unforgiving at the $1.5 million line. A buyer at $1,499,000 still gets a small rebate; a buyer at $1,500,000 gets nothing under this program. If you're negotiating a new build near that threshold, the price you settle on matters more than it seems.

Who Qualifies as a First-Time Home Buyer?

This is where most buyers get tripped up. The eligibility rules are stricter than the standard "haven't owned in four years" definition many Canadians know from the Home Buyers' Plan.

To qualify, every one of these conditions must be met:

• You're at least 18 years old.

• You're a Canadian citizen or permanent resident.

• You're buying the home as your primary residence.

• You'll be the first person to occupy the home after construction or substantial renovation.

Then there are two additional tests that disqualify a surprising number of buyers.

The four-year ownership lookback (and it's global)

Neither you, nor your spouse or common-law partner, can have lived in a home you (or they) owned—anywhere in the world—during:

• The current calendar year, or

• Any of the four preceding calendar years.

This is broader than most people assume. Owned a condo in another country a decade ago? Probably fine. Owned one in 2022 and rented since? You're out.

The lifetime limit (the spousal trap)

This is the rule that catches people: the FTHB GST rebate is a once-in-a-lifetime benefit per couple.

If your spouse or common-law partner has ever claimed this rebate before—even on a property they bought before you met them—you are not eligible. It doesn't matter that this is your first home. The lifetime limit applies to both of you as a unit.

Joint buyers: the "at least one" rule

Buying with a friend, sibling, or family member? Only one co-purchaser needs to qualify as a first-time buyer for the rebate to apply. But every co-owner still has to satisfy the four-year ownership lookback. The qualifying first-time buyer must be the named claimant on the rebate form.

What Counts as an Eligible Home?

Not every new property qualifies. The rebate applies to:

• A newly built home purchased from a builder (detached, semi-detached, townhouse, or condo)

• A new home on leased land, where the lease is at least 20 years or includes an option to purchase the land

• An owner-built home, or one you hired a contractor to build, where construction began on or after March 20, 2025

• Co-op shares where the share confers the right to occupy a unit in a new or substantially renovated co-op

• New mobile homes, modular homes, and floating homes

What "substantially renovated" actually means

This is one of the most misunderstood corners of the policy. The CRA's definition of substantial renovation requires that 90% or more of the interior of an existing home be removed or replaced—the "90% test." The foundation, exterior walls, supporting walls, roof, floors, and staircases don't need to be replaced.

Only livable areas count toward the 90% threshold. Finished basements and finished attics qualify; garages, crawl spaces, and unfinished basements don't.

A gut renovation that re-does 70% of the interior won't qualify. Neither will a major refresh that leaves the existing kitchen and bathrooms intact.

What does NOT qualify

• Resale homes (anything previously occupied)

• Investment or rental properties

• Secondary residences and vacation homes

• Properties purchased through corporations or partnerships

The rebate is for individuals buying a primary residence. Period.

The Fine Print That Can Cost You the Entire Rebate

The CRA has built strong anti-avoidance provisions into this rebate. A few situations have already tripped up real buyers.

Pre-March 20, 2025 agreements can't be re-papered

If your purchase agreement was signed before March 20, 2025, you don't qualify. Cancelling that agreement and re-signing on a later date to fit the new rules will not unlock eligibility. The CRA can—and will—disallow rebates where the re-signing appears designed to manufacture qualification.

Assignments inherit the original date

Taking an assignment of a pre-construction contract? Eligibility depends on when the original agreement was signed, not when you assumed it. If the developer's first buyer signed in 2024, that assignment can't qualify you—no matter when you bought in.

The clawback risk: you must actually live there

The rebate requires the home to be your primary residence. Sell it or rent it out shortly after closing and the CRA can claw the rebate back. Plans to "move in for a few months and then turn it into a rental" are a fast path to losing the $50,000. If your circumstances might change post-closing, talk to a tax professional before relying on the rebate.

The 2-year filing deadline

You have two years to file your claim—measured from the date ownership transferred (for homes purchased from a builder) or from substantial completion (for owner-built homes). Miss it, and the rebate is gone for good.

How to Claim the Rebate

There are two pathways, and which one applies depends on your builder and your timing.

Option 1: The builder credits the rebate at closing

For agreements made after Royal Assent (March 12, 2026), eligible builders can credit the rebate directly against your purchase price at closing. You and the builder jointly complete Form GST190, the builder submits to the CRA, and you simply pay a reduced amount upfront. This is the cleanest path.

Option 2: You apply directly to the CRA after closing

If the builder doesn't credit the rebate—or if the closing happened before Royal Assent—you'll pay the full GST/HST at closing and apply to the CRA yourself afterward.

The forms you need

• Form GST190 — for new homes purchased from a builder (including condos and homes on leased land)

• Form GST191 — for owner-built homes

You can file online through your CRA account (fastest) or by mail. CRA Guide RC4028 has full instructions. Claims are subject to audit, and processing can take up to six months.

One important note: Some early commentary on this rebate referenced "Form GST524." That's the New Residential Rental Property Rebate form—a different program entirely. For the FTHB rebate, you want GST190 or GST191.

What This Means for BC Buyers

For Greater Vancouver buyers, there's good news worth understanding clearly. BC doesn't apply PST to new home purchases, which means the federal 5% GST is the entire sales-tax story on a new build. The full federal rebate flows through to BC buyers without a provincial tax owing on top.

Better still, BC has two separate provincial programs that stack with the federal rebate for eligible first-time buyers of new builds:

BC First-Time Home Buyers' Program (PTT exemption)

For properties registered on or after April 1, 2024, the first $500,000 of fair market value is exempt from Property Transfer Tax for homes valued up to $835,000, saving up to $8,000. A partial exemption phases out between $835,000 and $860,000. This applies to both new and resale homes.

One critical nuance buyers often miss: the BC FTHB PTT exemption has stricter eligibility than the federal GST rebate. To qualify, you must:

• Have never owned a registered interest in a property that was your principal residence anywhere in the world, at any time (this is a lifetime test, not a four-year lookback).

• Have lived in BC for at least one year immediately before registering the property.

• Have filed at least two income tax returns as a BC resident in the last six taxation years.

That means a buyer who owned a primary residence outside Canada a decade ago might qualify for the federal GST rebate (which only looks back four years) but be disqualified from the BC FTHB PTT exemption (which requires never having owned). Don't assume eligibility for one program means eligibility for the other.

BC Newly Built Home PTT Exemption

A separate provincial PTT exemption for newly built homes. Effective April 1, 2024, the full exemption applies to new homes valued up to $1,100,000, with a partial exemption between $1,100,000 and $1,150,000. Notably, this one isn't limited to first-time buyers—any qualifying purchaser of a new build using it as a principal residence may qualify.

Three programs, one buyer

For a qualifying BC first-time buyer purchasing a new build, all three programs—the federal GST rebate, the BC First-Time Home Buyers' PTT exemption, and the BC Newly Built Home PTT Exemption—can apply together. Each has its own thresholds, forms, and tests. Each one alone is meaningful; combined, they materially change the math on a Vancouver-area new build.

A Note for Ontario Buyers

Ontario buyers face a more complicated picture because Ontario charges 13% HST (5% federal + 8% provincial), and the federal rebate only covers the federal portion. But two Ontario-specific measures could change the math significantly.

Two separate Ontario rebates are in motion

1. The Ontario First-Time Home Buyer HST Rebate (announced October 28, 2025)

This measure would rebate the full 8% provincial portion of HST for eligible first-time buyers, providing up to $80,000 in additional savings on the provincial side. The 2026 Ontario Budget confirmed alignment with the federal rebate's effective date of March 20, 2025. Status: subject to federal Excise Tax Act amendments; not yet enacted.

2. The Ontario Enhanced HST Rebate (tabled in the 2026 Ontario Budget on March 26, 2026)

This is the bigger one—and it's open to all eligible new-home buyers, not just first-timers. That includes move-up buyers, downsizers, and even purchasers of new residential rental properties. The structure of the combined federal + provincial relief, as set out in the budget and confirmed by Aird & Berlis, Osler, and CBC News:

Home Price	Combined Federal + Provincial HST Relief
Up to $1,000,000	Full 13% HST rebated — up to $130,000
$1,000,000 – $1,500,000	Flat $130,000 rebate maintained
$1,500,000 – $1,850,000	Declining from $130,000 down to $24,000
Above $1,850,000	Existing $24,000 provincial rebate only

Key conditions:

• Agreement of purchase and sale must be signed between April 1, 2026 and March 31, 2027

• Construction must begin on or before December 31, 2028

• Substantial completion required on or before December 31, 2031

• The home must be acquired as a primary residence or as a new residential rental property

Status: Tabled in the 2026 Ontario Budget. As of early May 2026, CBC News reported the budget was at third reading. Federal Excise Tax Act amendments are also required to release the federal 5% portion. Not yet enacted.

Where buyers qualify for both programs

If a first-time buyer qualifies for both the Ontario FTHB rebate and the broader Ontario Enhanced rebate, the rebate is the greater of the two, not stacked.

Important caution for Ontario buyers

Until the Ontario legislation passes and the federal amendments are made, builders cannot reliably credit the provincial rebate at closing. Buyers who close during this gap may need to pay full HST upfront and apply for retroactive relief once the law is in force. Given the dollar amounts at stake and how close to the line the legislation is, consult a real estate lawyer before signing during this window.

Common Questions Buyers Are Asking

My partner owned a condo three years ago. Do I still qualify?

No. The four-year lookback applies to both of you. If your partner owned and lived in a home in the current calendar year or any of the four preceding calendar years, neither of you qualifies.

I signed a presale contract in 2024. Does the rebate apply?

No. Eligibility starts only for agreements signed on or after March 20, 2025. Cancelling and re-signing to qualify is explicitly prohibited under the anti-avoidance rules.

Can I combine this with the FHSA and Home Buyers' Plan?

Yes. The FHSA and HBP are income tax programs (a registered savings account and an RRSP withdrawal, respectively). The FTHB rebate is an excise tax measure. They operate independently—a qualifying buyer can use all three together.

My spouse claimed a first-time-buyer GST rebate years ago. Can I claim it now?

No. The lifetime limit applies to both of you. If either of you has previously received this rebate, neither can claim it again.

Will the builder definitely credit the rebate at closing?

Not always. Builders may credit at closing using Form GST190, but they're not required to. Confirm in writing before signing whether the builder will credit the rebate, or whether you'll need to apply to the CRA directly afterward.

What This Means for the Greater Vancouver Market

The federal rebate arrives at a notable moment in the Vancouver-area market. Inventory levels are elevated, the presale segment has been working through completed and unsold units, and borrowing costs—while not at 2021 lows—have stabilized. Combined with BC's stackable PTT exemptions, the effective discount for a qualifying first-time buyer on a new build can be substantial.

That said, market dynamics cut both ways. In a market where developers are working through inventory and managing carrying costs, the rebate may translate primarily into real buyer savings rather than higher list prices. In tighter segments, some of the value could be absorbed by pricing adjustments. The outcome depends on the project, the developer, and the local supply picture—which is why working with an agent who knows the specific presale inventory in your target area matters.

A presale-focused buyers' agent can help you identify which projects are pricing competitively, which developments offer the best value relative to comparable resale, and—critically—help you avoid the assignment and re-papering traps that disqualify the rebate. They can also help you understand exactly what compensation they're receiving from a builder, which is information every buyer should ask for upfront.

The Bottom Line

The First-Time Home Buyers' GST Rebate is real, it's law, and for a qualifying buyer it can mean up to $50,000 back. It's also genuinely narrow:

• The four-year lookback and the spousal lifetime limit disqualify more buyers than people assume.

• A single date on a presale contract can void eligibility entirely.

• The home must actually be your primary residence—clawbacks are real.

• The $1.5 million ceiling is a hard cliff, not a guideline.

If you're a first-time buyer considering a new build, this rebate can meaningfully change what you can afford. But it deserves the same careful diligence as any other major financial decision: verify your eligibility with a tax professional, confirm in writing how your builder will handle the rebate, and work with an agent who understands both the program and the local new-construction market.

Trust the headlines for the broad strokes. Verify the details before you sign.
