How to calculate gst hst new housing rebate: Multiply the GST/HST on the first $350,000 of your purchase by 36%, then add your provincial rebate. Missing the 365-day filing window on Form GST190 or underestimating your rebate could cost you up to $3,000 or delay your closing by weeks. We cover province-specific charts, an interactive calculator, and real-life examples to guide you through every step.
Key takeaways
- Confirm eligibility for new, owner-built or purchased primary residences.
- Calculate federal rebate: 36% of GST paid, capped at $6,300 for homes under $450,000.
- Provincial HST rebates vary; verify specific percentages and caps for your province.
- Apply within two years of the home’s occupancy date using the correct CRA form.
- Consider fair market value limits; they impact your total eligible rebate amount.
How to Calculate Your GST/HST New Housing Rebate
Buying a new home is exciting, but costs can be overwhelming. The GST/HST New Housing Rebate offers a silver lining, helping offset some of the federal Goods and Services Tax (GST) or the federal portion of the Harmonized Sales Tax (HST) on new residential properties. How do you figure out your potential rebate? Let’s break it down.
Who is Eligible for the New Housing Rebate?
To qualify, the rebate is primarily for:
- Individuals who bought a new or substantially renovated house from a builder.
- Individuals who built a house or hired someone to build a house on their own land.
- Individuals who bought a mobile home or a new floating home.
- Individuals who bought a share in a housing co-operative.
The home must be your primary residence or that of a relation. It must also be the first sale or occupancy after construction or substantial renovation.
Key Information You’ll Need on Hand
Gather these essential details to calculate your rebate:
- Purchase Price: The amount paid for the new home, excluding GST/HST.
- GST/HST Paid: The total federal and provincial tax shown on your purchase agreement.
- Fair Market Value (FMV): The value of your home at substantial completion. This isn’t always the same as the purchase price.
- Occupancy Date: The date you first moved into the home.
Understanding Provincial GST/HST Rates
The total tax rate depends on your province. The federal GST portion is 5% across Canada, which HST provinces combine with their provincial sales tax. Here are the rates:
| Province/Territory | GST/HST Rate | Federal Portion (GST) |
|---|---|---|
| Alberta | 5% GST | 5% |
| British Columbia | 5% GST + 7% PST | 5% |
| Manitoba | 5% GST + 7% PST | 5% |
| New Brunswick | 15% HST | 5% |
| Newfoundland and Labrador | 15% HST | 5% |
| Northwest Territories | 5% GST | 5% |
| Nova Scotia | 15% HST | 5% |
| Nunavut | 5% GST | 5% |
| Ontario | 13% HST | 5% |
| Prince Edward Island | 15% HST | 5% |
| Quebec | 5% GST + 9.975% QST | 5% |
| Saskatchewan | 5% GST + 6% PST | 5% |
| Yukon | 5% GST | 5% |
Remember, the federal New Housing Rebate applies only to the 5% federal portion of the GST or HST, not the entire HST amount. Many provinces also offer their own provincial new housing rebates, calculated separately.
The Core Calculation: A Step-by-Step Walkthrough
The calculation depends on the 5% federal tax portion and your home’s fair market value.
Step 1: Determine the Federal GST/HST Paid
First, isolate the 5% federal component of the tax you paid.
- If you paid only GST (e.g., Alberta, BC, Manitoba): Your federal GST paid is the total GST shown on your invoice (5% of purchase price).
- If you paid HST (e.g., Ontario, New Brunswick, Nova Scotia): Your federal GST portion is 5/HST_Rate of the total HST paid. For instance, if you paid 13% HST in Ontario, and total HST was $30,000, your federal portion is (5/13) x $30,000 = $11,538.46. Alternatively, use 5% of the pre-tax purchase price.
Step 2: Calculate Your Initial Rebate Amount
The rebate is 36% of the federal GST/HST you paid (from Step 1).
- Calculation: Federal GST/HST Paid x 0.36
Step 3: Apply the Maximum Rebate Cap
The maximum federal GST/HST new housing rebate is $6,300.
- Compare: Your initial rebate (from Step 2) vs. $6,300.
- Result: Use the lower figure. If your Step 2 calculation was $7,000, your rebate cap is $6,300.
Step 4: Apply the Fair Market Value (FMV) Cap and Phase-Out
The rebate is fully available for homes with an FMV of $350,000 or less. It phases out for homes between $350,000 and $450,000. If your home’s FMV is $450,000 or more, you’re generally not eligible.
- If FMV is $350,000 or less: Your rebate is the amount from Step 3.
- If FMV is between $350,000 and $450,000: Your rebate is reduced. This complex formula reduces the rebate for every dollar the FMV exceeds $350,000.
- If FMV is $450,000 or more: No rebate is available.
Real-Life Example: A New Homeowner’s Rebate
Consider this scenario for an Ontario home:
- Purchase Price: $400,000
- HST Paid (13%): $52,000
- Fair Market Value (FMV) at substantial completion: $420,000
Here’s the federal rebate calculation:
- Determine Federal GST Portion: For 13% HST, the federal portion is 5/13 of the total HST paid.
- Federal GST portion = ($52,000 x 5) / 13 = $20,000
- Calculate Initial Rebate Amount: 36% of the federal GST portion.
- Initial Rebate = $20,000 x 0.36 = $7,200
- Apply Maximum Rebate Cap: The maximum rebate is $6,300.
- Since $7,200 is greater than $6,300, we use $6,300.
- Apply Fair Market Value (FMV) Cap and Phase-Out: FMV is $420,000, between $350,000 and $450,000, so the $6,300 rebate is reduced.
- Excess FMV = $420,000 – $350,000 = $70,000
- Reduction Factor = ($450,000 – $420,000) / $100,000 = 0.3
- Adjusted Rebate = $6,300 x 0.3 = $1,890
In this example, the homeowner qualifies for a federal GST/HST New Housing Rebate of $1,890.
Important Considerations & Pro Tips
- Fair Market Value is Key: Don’t confuse purchase price with FMV; the CRA uses FMV for eligibility. Self-builders might need an appraisal.
- Timely Application: Apply within two years of occupying the new house. Don’t miss the deadline!
- Keep Records: Retain all supporting tax documents: purchase agreement, adjustments, proof of HST/GST paid, and invoices for self-built homes.
- Provincial Rebates: Many provinces offer separate rebates for the provincial portion of HST or PST. Don’t overlook these; they have distinct applications and criteria.
- Self-Built vs. Builder Purchases: Use the correct application form: Form GST191 for self-built homes, Form GST190 for builder purchases. You can also explore options for online GST, HST, and QST filing.
Calculating the GST/HST New Housing Rebate, especially with FMV rules and provincial variations, can be intricate. If you’re unsure or want to maximize your rebate, it’s wise to consult with a qualified tax professional for comprehensive tax planning strategies.

Province-Specific Rebate Details and Thresholds
Understanding the GST/HST New Housing Rebate involves more than just federal rules for refunds, payments, and credits; Canada’s provinces add unique complexities. Your location significantly impacts your eligible rebate when building a new home or renovating.
The Tale of Two Taxes: GST vs. HST
First, let’s distinguish between GST-only provinces and those using the Harmonized Sales Tax (HST).
- GST-Only Provinces: Alberta, British Columbia, Manitoba, Quebec, Saskatchewan, Yukon, Northwest Territories, and Nunavut. You pay 5% GST here. (Quebec also has QST; federal rebate applies only to GST.)
- HST Provinces: Ontario, New Brunswick, Newfoundland & Labrador, Nova Scotia, and Prince Edward Island. Here, federal 5% GST combines with provincial sales tax for a single, higher HST.
Rebate Details for GST-Only Provinces
In GST-only provinces, the federal new housing rebate is straightforward: 36% of the 5% GST paid, up to a maximum of $6,300. Full rebate applies up to $350,000. For homes between $350,000 and $450,000, the rebate decreases; over $450,000, homes generally don’t qualify. For example, a $300,000 new Alberta home would incur $15,000 in GST; your federal rebate would be 36% ($5,400).
HST Provinces: Double the Considerations
HST provinces are more complex, with federal and provincial rebate components. Rates vary by province:
| Province | HST Rate | Federal Rebate | Provincial Rebate Notes |
|---|---|---|---|
| Ontario | 13% | Up to 36% of 5% federal | 75% of 8% provincial, up to $24,000 (no property value cap for some purchases, consult CRA) |
| New Brunswick | 15% | Up to 36% of 5% federal | 36% of 10% provincial, up to $3,000 (property thresholds apply) |
| Nova Scotia | 15% | Up to 36% of 5% federal | 36% of 10% provincial, up to $3,000 (property thresholds apply) |
| Newfoundland & Labrador | 15% | Up to 36% of 5% federal | 36% of 10% provincial, up to $3,000 (property thresholds apply) |
| Prince Edward Island | 15% | Up to 36% of 5% federal | 36% of 10% provincial, up to $3,000 (property thresholds apply) |
The federal HST rebate follows GST-only thresholds: 36% of the 5% federal component, with full rebates up to $350,000 and partial up to $450,000.
Provincial portions vary. Ontario’s provincial new housing rebate is typically 75% of the 8% provincial HST portion, up to $24,000. Notably, for most new homes, its upper purchase price limit is waived, unlike the federal cap; higher-value homes may still qualify.
Other HST provinces (New Brunswick, Nova Scotia, Newfoundland & Labrador, Prince Edward Island) typically offer a provincial rebate of 36% of their HST portion. These often include property value thresholds similar to the federal rebate; homes over $450,000 may not qualify. Always verify specific provincial guidelines, as they can change. It’s wise to stay informed about tax compliance and filing guidance.
Navigating Rebate Thresholds: A Quick Look
Federal thresholds ($350,000 for full, $450,000 for partial/no) are crucial for the 5% GST component. Provincial rebates often have different caps. Consulting with a qualified tax professional is essential to claim all eligible amounts.
Nuanced federal and provincial rules mean predicting your exact rebate without expert guidance can lead to missed opportunities or errors. It’s about interpreting specific regulations for your unique situation.
