GST New Build Rebate for First-Time Buyers in Alberta: What You Need to Know in 2026

Buying a newly built home in Alberta just got significantly less expensive. A federal law that came into force on March 12, 2026 eliminates the GST entirely for eligible first-time buyers purchasing new homes valued up to $1 million. On a $700,000 new build, that's $35,000 back in your pocket. On a $900,000 home, it's $45,000. Most first-time buyers we work with had no idea this rebate existed — and some have already missed part of the deadline without knowing it.

Here is everything you need to know about the GST new build rebate for first-time buyers in Alberta.

What Is the First-Time Buyers' GST Rebate?

The First-Time Home Buyers' GST Rebate (FTHB GST Rebate) is a federal program that eliminates the 5% GST on newly built homes for eligible first-time buyers. It was introduced as part of the federal government's housing affordability measures and became law on March 12, 2026, when Bill C-4 — the Making Life More Affordable for Canadians Act — received Royal Assent.

Before this rebate existed, the standard GST/HST New Housing Rebate gave buyers a partial refund on new homes, but it was capped at roughly $6,300 — a number that made sense when new homes cost $300,000 but means very little today. The new FTHB rebate replaces that cap with something that actually reflects what new homes cost in Alberta.

In Alberta, there is no HST and no provincial sales tax. New home purchases are subject only to the federal 5% GST. So the FTHB rebate applies specifically to that 5%.

How Much Can You Save on a GST New Build Rebate in Alberta?

The savings scale with the purchase price:

• Home valued up to $1,000,000: Full rebate — 100% of the GST paid, up to a maximum of $50,000
• Home valued between $1,000,000 and $1,500,000: Partial rebate on a sliding scale
• Home valued above $1,500,000: No rebate

Here are practical examples for Alberta buyers:

For homes at or below $1 million — which covers the majority of new single-family homes in Calgary's suburbs and most new condos — the rebate eliminates the GST entirely.

Who Qualifies for the GST New Build Rebate in Alberta?

To qualify for the FTHB GST rebate, you need to meet all of the following conditions:

You must be a first-time home buyer. The CRA defines this as someone who has not lived in a home they owned — or that their spouse or common-law partner owned — at any time during the calendar year of purchase or the four preceding calendar years. If you owned a home five or more years ago and have been renting since, you may qualify again. This catches many people off guard in a good way.

Your purchase agreement must have been signed on or after March 20, 2025. The rebate applies retroactively to purchase agreements from Budget 2025 day forward. If you signed before that date, the old GST/HST New Housing Rebate rules apply instead. Confirm your specific eligibility date with a mortgage broker or tax professional.

The home must be newly built. This includes homes purchased directly from a builder, newly constructed condominiums, homes built on leased land, and substantially renovated homes (where at least 90% of the interior was removed or replaced). Resale homes do not qualify because resale transactions are not subject to GST. If you are still learning how new build mortgages work in Canada, our separate guide covers rate holds, deposit structures, and appraisal risks.

The home must be your primary residence. Investment properties, rental properties, and vacation homes are not eligible. The home must be occupied as the primary place of residence by you or a qualifying relation.

You must be an individual who is at least 18 years old. Corporations and partnerships cannot claim this rebate.

Construction must begin before 2031 and be substantially completed before 2036. This means the program covers purchases that happen over the next several years, not just immediate closings.

One important note: if you are purchasing with a spouse or partner who does not qualify as a first-time buyer, your eligibility may be affected. The qualification rules apply to all individuals on title. Discuss this with a broker before you sign anything.

How to Claim the GST Rebate — Two Ways It Gets Applied

Most buyers do not need to do anything extra. Here is how the two scenarios work:

Option 1 — Builder applies it at closing (most common)

In most cases, your builder will apply the FTHB rebate directly and reduce the purchase price accordingly. Your purchase agreement may read something like "price includes GST, net of applicable rebates." If that is the case, you do not need to file a separate rebate application — the builder handles it and applies directly to the CRA on your behalf using Form GST190.

Check your purchase agreement carefully. If it says you are paying GST and there is no mention of a rebate credit, or if the GST line shows a balance payable, move to Option 2.

Option 2 — You apply directly to the CRA

If you signed your purchase agreement on or after March 20, 2025, but took possession of the home before Royal Assent was granted on March 12, 2026, your builder could not have applied the new rebate at closing because the law was not yet in force. In that situation, you likely paid the full GST to the builder and will need to apply to the CRA directly to receive your rebate retroactively.

You submit your application through your CRA My Account online or by mail using Form GST190. The CRA will issue a refund directly to you.

One critical deadline: You have two years from the date you took ownership or finished construction to file your rebate claim. Missing that window means forfeiting the rebate entirely. If you are in this situation, act now — do not let the two-year clock run out.

How the GST Rebate Works With Your FHSA and Home Buyers' Plan

The FTHB GST rebate is a separate program from the First Home Savings Account (FHSA) and the RRSP Home Buyers' Plan (HBP). You can use all three at the same time, and doing so dramatically changes what you can afford as a first-time buyer in Alberta.

Here is how stacking these programs works:

• FHSA: Up to $40,000 per person, tax-deductible on the way in and tax-free on the way out. Couples can each open an FHSA, giving them up to $80,000 combined.
• Home Buyers' Plan: Withdraw up to $60,000 per person from your RRSP, interest-free. A couple can access up to $120,000 combined.
• FTHB GST Rebate: Saves up to $50,000 in GST on the new home itself.

Between these three programs, a couple buying a new build in Alberta could access up to $250,000+ in combined tax-advantaged savings and rebates. That is a material difference in what is achievable.

The "first-time buyer" definition is consistent across all three programs. If you qualify for the FHSA and HBP, you will almost certainly qualify for the GST rebate as well. For a deeper look at these programs, read our guide to first-time home buyer programs in Canada.

Frequently Asked Questions

Does the GST new build rebate apply to resale homes in Alberta?

No. The FTHB GST rebate applies only to newly built homes purchased directly from a builder, newly constructed condos, and substantially renovated homes. Resale homes are not subject to GST in the first place, so there is no rebate to claim on an existing home.

What if my spouse is not a first-time buyer — do I still qualify for the GST rebate?

If your spouse or common-law partner owned a home they lived in during the four calendar years before your purchase, your eligibility for the rebate may be affected. The rules require that all individuals on title meet the first-time buyer criteria. This is an important detail to clarify before signing a purchase agreement. A broker can help you understand your specific situation.

My builder says the price includes GST. Does that mean the rebate was already applied?

Not necessarily. "Price includes GST" can mean the builder calculated the purchase price to absorb the gross tax. It does not always mean the FTHB rebate was applied. Ask your builder specifically whether the FTHB rebate is included and whether they are filing Form GST190 on your behalf.

Can I claim the GST rebate myself if my builder didn't apply it?

Yes. If you are eligible and the builder did not credit the rebate, you can apply directly to the CRA through your CRA My Account. You will need your purchase agreement, proof of ownership, and evidence that you meet the first-time buyer criteria. The two-year deadline from taking ownership still applies.

How long does it take to receive the GST rebate from the CRA?

The CRA does not publish a fixed processing timeline for the FTHB rebate, as the program is newly in force. As a general reference, standard CRA rebate applications are typically processed within 8 to 16 weeks. Submitting your application promptly and correctly — with all required documentation — reduces delays.
