The New First-Time Home Buyers’ GST/HST Rebate: What Canadian Buyers Need to Know

If you’re planning to buy your first home in Canada, you need to know about a significant change that could save you tens of thousands of dollars.

In March 2026, Bill C-4 received Royal Assent, officially making the new First-Time Home Buyer GST Rebate law. This rebate is available to qualifying purchasers if the agreement of purchase and sale for the home was entered into with the builder on or after March 20, 2025 and before 2031.

The window of opportunity is open. Here’s what you need to understand.

What the Federal Rebate Actually Covers

The new rebate eliminates up to 100% of the GST (or federal portion of the HST) paid on qualifying new homes.

Here’s how it breaks down:

• For homes valued at $1 million or less: You can recover the full 5% GST, up to a maximum rebate of $50,000. This means zero federal GST on your new home purchase.
• For homes valued between $1 million and $1.5 million: The rebate phases out on a straight-line basis. If you purchase a home for $1.25 million (the midpoint), you’re eligible for 50% of the maximum rebate, which equals $25,000.
• For homes valued at $1.5 million or above: No rebate is available.

This represents real money back in your pocket at a time when every dollar counts.

Who Qualifies as a First-Time Buyer

The definition is stricter than you might think.

You qualify as a first-time home buyer if you have not lived in a residential unit (whether in or outside Canada) that you owned or that your spouse or common-law partner owned in the calendar year or in the four preceding calendar years.

That’s a five-year lookback period. If you or your spouse owned a home anytime in the past five years, you don’t qualify for this rebate.

The home must also be your primary place of residence. The Canada Revenue Agency defines this as the residence you live in on a permanent basis. You may have more than one residence, but you can only have one primary place of residence.

Investment properties don’t qualify. Corporations and partnerships are also excluded from claiming this rebate.

How Ontario Buyers Can Stack Rebates

If you’re buying in Ontario, the savings get even better, and the numbers are substantial.

On March 25, 2026, the Ontario government announced the most significant change to residential HST rules in the province’s history. For twelve months (covering Agreements of Purchase and Sale signed between April 1, 2026 and March 31, 2027), eligible buyers of newly constructed homes may claim a combined federal and provincial rebate of up to $130,000.

Here’s how it works:

Ontario’s temporary enhancement rebates the entire 8% provincial portion of the HST (up to $80,000) for eligible purchases of qualifying newly built homes valued at up to $1 million. The federal government agreed to partner with Ontario and provide funding that allows Ontario to also rebate the 5% federal portion (up to $50,000).

When you combine the Ontario rebate with the federal rebate, eligible first-time home buyers could qualify for up to $130,000 in savings when purchasing an eligible newly constructed (or substantially renovated) home valued at up to $1 million. For homes between $1 million and $1.5 million, the $130,000 rebate remains flat, providing maximum relief across this price range.

Important note: The Ontario rebate applies to all eligible buyers, not only first-time buyers, who sign an Agreement of Purchase and Sale between April 1, 2026 and March 31, 2027.

This represents a dramatic shift in policy. Before 2026, Ontario buyers had access to a New Housing Rebate that phased out entirely once a home’s purchase price exceeded $450,000, with a maximum provincial rebate of just $24,000. Because most new homes in the Greater Toronto Area are priced above $450,000, the majority of buyers received little to no meaningful rebate. The 2026 enhancement changes this completely, extending full HST relief to homes valued up to $1 million.

Pro Tip: Where you’re eligible for the federal first-time home buyers’ GST rebate, claim that rebate before claiming the Ontario Enhanced New Housing Rebate.

How to Actually Claim Your Rebate

The application process depends on how you acquired your home. There are two distinct pathways:

Option 1: Home Purchased from a Builder

This option applies if you purchased a newly constructed home from a builder or bought a share of the capital stock of a co-operative housing corporation.

Method A: Builder Credits the Rebate at Closing

Your builder can credit the First-Time Home Buyers’ GST/HST rebate directly against the purchase price when ownership transfers to you. This works the same way as the existing GST/HST new housing rebate, the builder reduces the total amount payable by the rebate amount.

This is the simplest approach. You pay less at closing, and the builder handles the paperwork with the CRA on your behalf.

Method B: Apply Directly to the CRA

If your builder doesn’t (or can’t) credit the rebate at closing, you’ll need to apply directly to the Canada Revenue Agency yourself.

This has been common for buyers who closed between March 20, 2025 (when the rebate took effect) and March 12, 2026 (when Royal Assent occurred). During this period, builders couldn’t credit the rebate because the legislation wasn’t yet finalized.

Time limit: You must submit your application within two years of the date ownership is transferred to you.

Option 2: Owner-Built or Substantially Renovated Home

This option applies if you built your own home on land you own or lease, or if you substantially renovated your existing home to the point where it qualifies as a “new” home under the rebate rules.

For owner-built homes, you must apply directly to the CRA. There’s no builder to credit the rebate for you.

Time limit: You must submit your application within two years of the date construction is substantially completed.

Ontario buyers: For Ontario’s enhanced rebate (available for agreements signed between April 1, 2026 and March 31, 2027), the CRA application forms are expected to be available by mid-July 2026. If you’ve already closed or completed construction, don’t worry, the rebate is retroactive, and you can claim it once the forms are released.

Real-World Examples of What You’ll Save

Let’s look at actual numbers.

Example 1: $900,000 Purchase

You purchase a newly constructed home for $900,000. GST at 5% would normally be $45,000. Under the new program, you recover the full amount. Your federal GST is eliminated.

Example 2: $1,250,000 Purchase

You purchase a new home for $1,250,000. The maximum rebate of $50,000 is gradually reduced at this price point. You receive approximately $25,000, meaning a portion of the GST remains payable.

Example 3: Ontario Buyer at $1,000,000

You purchase a newly built home in Ontario for $1,000,000 between April 1, 2026 and March 31, 2027. You qualify for both the federal and Ontario rebates. Your total rebate: $130,000. The full 13% HST is eliminated.

These are not small numbers. For many first-time buyers, GST/HST on newly constructed homes represents a significant additional cost during the purchase process.

Opportunities for Builders and Developers

The construction industry stands to benefit from increased demand for newly built homes. By reducing the effective purchase price for buyers, the government is creating an incentive that may stimulate new home sales and improve project viability.

Builders could see:

• Increased buyer interest in new developments.
• Faster absorption rates for inventory.
• Improved confidence to launch future projects.
• Greater certainty when planning long-term investments and workforce needs.

As Ontario continues to pursue ambitious housing supply targets, measures that encourage new construction are likely to play a critical role in supporting industry growth.

Impact on Real Estate Professionals

For real estate agents, brokers, and related professionals, the expanded rebate provides a compelling value proposition for clients considering new construction. Understanding the details of the rebate can help advisors identify opportunities for buyers and position new-build properties more competitively within the market.

The policy may also generate increased transaction activity, benefiting professionals across residential real estate, mortgage financing, legal services, and home inspection sectors.

Next Steps for Your Home Purchase

If you’re considering purchasing a new home as a first-time buyer, here’s what you should do:

1. Verify your eligibility. Confirm you meet the five-year ownership requirement and that the home will be your primary residence.

2. Understand the timeline. The rebate applies to agreements of purchase and sale entered into on or after March 20, 2025 and before 2031. If you’re in Ontario, the enhanced rebate window runs from April 1, 2026 to March 31, 2027.

3. Coordinate with your builder. Ask whether they will credit the rebate at closing or if you’ll need to apply directly to the CRA.

4. Get professional guidance. Tax planning around real estate purchases involves multiple layers of federal and provincial programs. Working with an experienced accountant ensures you maximize your savings and avoid costly mistakes.
