How to claim Canada’s $50,000 federal first-time homebuyer GST rebate

The Canada Revenue Agency (CRA) is now accepting applications for the first-time homebuyers GST rebate. Following Royal Assent of Bill C-4 on March 12, 2026, eligible Canadians can claim up to $50,000 on federal tax paid on new construction homes. 

This rebate specifically targets the high cost of newly built housing by offering substantial relief to those entering Canada’s property market. 

However, the rules are complex and can be confusing. For example, the property cannot be a traditional resale home, and the eligibility test looks back up to five years into your global homeownership history.  

“One of the biggest mistakes I see is people assuming they qualify without fully understanding the rules,” says Rasha Ingratta, a mortgage agent with Mortgage Intelligence. “They hear ‘first-time homebuyer’ or ‘new home rebate’ and naturally think it applies to them.” 

Furthermore, the exact timeline between signing your contract and when you take occupancy can determine whether your builder can credit this money upfront or you need to submit a manual claim.

How to receive your $50,000 GST rebate: Builder credits versus CRA direct claims

There are two ways to receive the GST rebate. 

1. Builder credit at closing: If you sign your purchase agreement today, most builders will simply deduct the rebate amount from your final statement of adjustments. The builder then claims the rebate from the government on the back end. You pay less money on your closing day and skip rebate paperwork.
2. Direct claim to CRA. Directly applying to CRA is your best option if you build your own home, complete a substantial renovation, or if your builder refuses to credit the rebate upfront. You’ll need to file Form GST190 and submit it to the tax authorities. There’s a strict two-year deadline from your closing date to submit your paperwork; otherwise, you’ll likely forfeit the money entirely.

Here are four rules to check your eligibility for the federal first-time homebuyer GST rebate:

What properties qualify for GST rebate?

The most common misconception about the $50,000 first-time homebuyer GST rebate is that it applies to any first home purchase. This is incorrect. A standard resale property isn’t eligible, regardless of your first-time buyer status.

The rebate is designed to spur new housing units. To qualify, your home must fit into one of three specific categories: 

1. A newly constructed home purchased directly from a builder 
2. An owner-built home, where you hire contractors or build the house yourself on a vacant lot 
3. A substantially renovated home 

For a renovation to qualify as substantial, the CRA requires that 90% or more of the existing interior be removed or replaced. The 90% test can exclude certain features like foundation, exterior walls, interior supporting walls, floors, roof, and staircases; it only applies to livable areas. 

Are you really a first-time buyer?

The government applies a very specific legal definition to the term ‘first-time homebuyer’ to qualify for the rebate. You must have the intention to use the property as your primary residence and—more importantly—you must pass the four-year rule.

The four-year rule dictates that neither you nor your spouse or common-law partner can have owned and lived in a primary residence during the current calendar year or the four preceding calendar years. This rule applies to property owned anywhere in the world, not just in Canada.

Example 1: A buyer previously owned a primary residence but sold it in 2022. If they purchase a new build in 2026, they likely won’t qualify. The CRA looks at the current year (2026) and the four preceding years (2025, 2024, 2023, and 2022). It fails the four-year rule test. 

Example 2: If that same buyer waits to take ownership of the property in 2027, then their status changes. In 2027, the four preceding years are 2026, 2025, 2024, and 2023, so their 2022 homeownership should pass the rule. 

How to calculate your refund

The rebate specifically refunds the 5% federal GST portion of your purchase price, up to a maximum of $50,000 on homes priced at $1 million. For homes priced above $1 million, the rebate enters a linear phase-out. It slowly decreases until it reaches zero at the $1.5 million mark.

Here is how much GST you can be refunded based on your first home purchase price:

For the $700,000 home, the total federal tax is $35,000. Because the home is under the $1 million threshold, you can apply for the entire $35,000. 

At $1 million, you hit the absolute maximum rebate of $50,000. 

At $1.25 million, the purchase price is exactly halfway through the phase-out zone. Therefore, the $50,000 maximum rebate is cut exactly in half, leaving you with $25,000.

If your home falls anywhere in this phase-out zone between $1 million and $1.5 million, you can calculate your exact refund by subtracting your purchase price from $1,500,000 and multiplying the result by 10 percent:

GST Rebate = ($1,500,000 - Purchase Price) × 0.10

Example: You purchase a newly built home for $1,150,000:

($1,500,000 - $1,150,000 = $350,000) × 0.10 = $35,000

In this scenario, your total GST rebate would be $35,000.

How the GST rebate affects your mortgage down payment

Some buyers might be hoping to use this tax refund to help secure their mortgage. Unfortunately, a lender won’t use this rebate during your mortgage approval process.

“When there are potentially thousands of dollars available through a government program, you want to understand exactly what you qualify for before making financial decisions based on receiving that money,” says Ingratta.

To get a mortgage in Canada, you must prove you have the required down payment in your own bank account. Because the government rebate arrives after your closing date, it cannot be used to satisfy your upfront down payment requirements. 

You must fund the entire closing cost first and use the eventual rebate to replenish your savings.

Ingratta adds that buyers should be careful “not to include a rebate in their budget until they have confirmed that they qualify for it. Know your numbers first and your qualifications and never make assumptions until the funds have entered your bank account. Government programs can be a wonderful opportunity, but you still need to do your homework.”

Checklist for retroactive applicants of first-time homebuyer GST rebate

The legislation includes an unusual retroactive quirk. The rebate bill (C-4) received Royal Assent on March 12, 2026. However, it applies to purchase agreements signed on or after March 20, 2025—almost a full year prior.

Anyone who bought a home and transferred ownership during that one-year gap wouldn’t have received a builder credit at closing because the law was not yet official. Many of these buyers may not realize they could have tens of thousands of dollars in available rebates. 

If you closed between March 2025 and March 2026, you must claim the funds directly from the CRA.

Here is your checklist for securing your retroactive refund:

• Verify your purchase agreement was signed on or after March 20, 2025
• Confirm the ownership transfer date fell before March 12, 2026
• Check your final statement of adjustments from your real estate lawyer to confirm no GST rebate was credited
• Gather your final closing documents and your official proof of occupancy
• Download and complete Form GST190 from the federal government website
• Submit the application before your two-year deadline expires

How to qualify for Ontario's $80,000 Enhanced New Housing Rebate

If you are buying a home in Ontario, there’s currently an option to stack benefits with an enhanced provincial window. 

Ontario’s Harmonized Sales Tax (HST) includes a federal 5% and 8% provincial tax. While the federal GST rebate program offers 5% back, the province has enhanced its own rebate for the 8% side. 

This enhanced provincial window applies strictly to homes that close between April 1, 2026, and March 31, 2027. During this one-year period, you can apply for both the maximum federal GST rebate and the enhanced provincial HST rebate simultaneously.

What are Ontario provincial first-time homebuyer rebate specifications

Under this temporary expansion, the enhanced provincial rebate covers the 8% provincial portion of the HST, capped at a maximum of $80,000. When stacked with the federal rebate (which covers up to $50,000 of the 5% federal portion), buyers can receive a combined total tax relief of up to $130,000. 

Homes priced between $1 million and $1.5 million may be eligible for the maximum $80,000 rebate, while homes under $1 million would apply for the exact provincial tax they paid. For homes priced above $1.5 million, the provincial rebate amount gradually phases down to $24,000 at the $1.85 million mark and beyond. 

Example: You purchase a newly built home for $1,000,000. The total 13% HST on the purchase is $130,000 ($50,000 for the 5% federal portion and $80,000 for the 8% provincial portion). By stacking both programs, it’s possible to recover the full $130,000, completely offsetting HST on your new home.

Frequently Asked Questions (FAQs)

Does my spouse's previous homeownership disqualify me from the GST rebate?

Yes—if your legal spouse or common-law partner owned and lived in a primary residence during the current calendar year or the four preceding years, neither of you can claim the rebate. It does not matter if your name was completely absent from their previous mortgage or property title.

What happens if I signed my purchase agreement before March 20, 2025?

If your builder contract was signed prior to March 20, 2025, you’re probably excluded from the new $50,000 maximum rebate. The government draws a hard line on the signature date. You may still qualify for the older, standard GST new housing rebate, but the financial benefit is significantly lower and it phases out on homes priced above $450,000.

How long does the CRA take to process the first-time homebuyer GST rebate claim?

If you are required to submit a direct claim via Form GST190 rather than receiving a builder credit at closing, you should expect a waiting period. The standard processing time is up to 120 days from the date the CRA receives your complete application. Ensuring all your legal documents and builder schedules are included can help prevent unnecessary delays.
