Bill C-4 became law on March 12, 2026. If you’re a first-time buyer purchasing a new build in Alberta, you may be eligible for up to $50,000 back in GST. The eligibility rules are strict and easy to misread — and one mistake costs you the entire rebate. This post explains exactly how it works, who qualifies, and what to do right now.
A lot of the information circulating right now about the new GST rebate is either out of date or missing key details. Some posts are still citing the wrong eligibility cutoff date. Others don’t mention that couples need to check both partners’ ownership history — not just the primary applicant.
I want to make sure Alberta buyers have the accurate picture. So let’s go through the whole thing clearly.
What Is the New GST Rebate — and Why Does It Matter?
On March 12, 2026, the federal government’s Bill C-4 — the Making Life More Affordable for Canadians Act — received Royal Assent and became law.
What it does: it eliminates 100% of the GST on new home purchases by eligible first-time buyers, on properties priced up to $1 million. That’s a significant change from the old partial GST/HST rebate, which was capped at homes under $450,000 and only returned a fraction of the tax paid.
For Alberta buyers, this is especially meaningful. Alberta has no provincial land transfer tax — already an advantage over Ontario and BC buyers. Now, with the GST eliminated on qualifying new builds, the cost gap between buying here versus other provinces widens further.
Illustrative Savings — How the Math Works
The table below shows how much GST a buyer would save under the rebate. These are illustrative calculations based on the 5% federal GST rate. They are not quotes, guarantees, or representations of any specific transaction.
| Home Price | 5% GST Payable | Rebate (Saving) |
| $500,000 | $25,000 | $25,000 |
| $700,000 | $35,000 | $35,000 |
| $900,000 | $45,000 | $45,000 |
| $1,000,000 | $50,000 | $50,000 |

Who Qualifies — And the Rules That Catch People Off Guard
The rebate is generous, but the eligibility criteria are strict. These are the three rules I see causing the most confusion right now.
Rule 1: The Four-Year Look-Back
You don’t qualify if you — or your spouse or common-law partner — owned and lived in a home at any point during the four calendar years before your purchase date. Renting for three years after selling a previous home may not be enough. The clock runs from the year of your purchase, not from today.
Your partner’s ownership history counts, even if you personally have never owned property. This is the rule that surprises people most.
Rule 2: Your Purchase Agreement Date Is the Eligibility Trigger
The cutoff date is March 20, 2025. Your purchase agreement must have been signed on or after that date. Possession date, closing date, and funding date don’t determine eligibility — the agreement date does.
Note: some earlier coverage of this rebate cited May 27, 2025, as the cutoff. That date has since been corrected by the CRA. The correct date is March 20, 2025. If your agreement was signed between those two dates, you may still qualify — but verify directly with the CRA or your mortgage professional.
Rule 3: If You Already Closed, You May Need to Claim It Yourself
Because the legislation wasn’t in force until March 12, 2026, builders closing deals before that date couldn’t apply the rebate on your Statement of Adjustments. If you paid full GST at closing and your agreement was signed after March 20, 2025, you will need to apply to the CRA directly for a retroactive refund. This is not automatic.
HYPOTHETICAL EXAMPLE — For illustration only. This is not based on a real client or transaction.
Scenario: Two people purchase a newly built townhome in Calgary. The purchase agreement is signed in June 2025. They take possession in February 2026 and pay full GST at closing.
Because the agreement was signed after March 20, 2025, they fall within the eligible window. However, because they closed before March 12, 2026 (the date Bill C-4 received Royal Assent), their builder could not apply the rebate at closing.
In this scenario, the buyers would need to apply to the CRA retroactively to claim the rebate. The amount would depend on the home’s purchase price and their individual eligibility — which must be verified against the four-year look-back rule for both partners. This is one reason why getting professional guidance before closing — not after — matters.
What This Means Specifically for Alberta Buyers
Alberta already has structural advantages that other provinces don’t. There’s no provincial land transfer tax here — buyers in Ontario purchasing at similar price points pay thousands in land transfer fees that Alberta buyers don’t. Add the GST elimination and first-time buyers here are working with a meaningfully different cost picture than their counterparts in other provinces.
New construction is active across Alberta right now. Communities like Mahogany and Cornerstone in Calgary, and Keswick and Glenridding in Edmonton, have had strong new build activity. If you’re considering new construction, confirm with the builder and your broker that current projects qualify — not all new builds are automatically eligible, and inventory and availability change.
One thing worth flagging: new construction comes with its own set of considerations beyond the rebate — builder contract terms, possession timelines, and deposit structures differ from resale purchases. Make sure you understand the full picture before making new construction your strategy just for the rebate.
What to Do Right Now
- Confirm your purchase agreement date. If it’s March 20, 2025 or later, you’re in the eligible window — but you still need to verify the other criteria.
- Check the four-year look-back for both you and your partner. Be honest. If either of you owned a principal residence in 2022, 2023, 2024, or 2025, that could affect eligibility.
- If you closed before March 12, 2026 and paid full GST: gather your closing documents and contact the CRA about a retroactive claim. Don’t assume it will happen automatically.
- If you’re still in the pre-purchase phase: factor the rebate into your financial plan carefully — but don’t count on it until eligibility is confirmed. The timing of when you receive the funds matters for your down payment and cash flow planning.
- Talk to your mortgage broker before the builder’s preferred lender. Builders often have in-house financing options, but those aren’t always the most favorable terms for you. A broker can compare lenders and factor the rebate into your overall mortgage structure.
What This Means for You
The GST rebate is real and it’s significant. But it only matters if you qualify — and qualifying requires checking a few things that aren’t obvious from the headlines.
Your situation is specific to you. The rebate might be a major part of your strategy, or it might not apply at all. Either way, it’s worth knowing where you actually stand before you build your plan around it.
Frequently Asked Questions
Does the rebate apply to homes over $1 million?
It depends on the price. Under Bill C-4, the full GST elimination applies to new builds priced at $1 million or under — saving up to $50,000. For homes priced between $1 million and $1.5 million, a partial rebate applies on a sliding scale. Above $1.5 million, no rebate is available. Verify current details at canada.ca, as program rules can change.
I sold a home in 2022 and have been renting since. Do I qualify?
Possibly not. The four-year look-back runs from the calendar year of your purchase. If you owned and lived in a home in 2022, and you’re purchasing in 2026, that’s within the four-year window. The exact dates matter and eligibility should be verified directly with the CRA or a licensed professional — don’t assume either way.
My partner has never owned a home but I have. Can we still get the rebate?
No. If either partner owned a principal residence within the four-year look-back window, the household does not qualify. The rule applies to both parties, not just the primary applicant.
I closed in February 2026. Is it too late?
Not necessarily. If your purchase agreement was signed on or after March 20, 2025, you may still be eligible. Because the legislation wasn’t yet in force at closing, the rebate won’t be on your closing documents — you’ll need to apply to the CRA retroactively. Speak with your accountant or mortgage professional about the process and confirm the steps directly with the CRA.
Ready to Know Where You Stand?
The GST rebate is one piece of a larger picture. If you’re buying a new build in Alberta, there are other programs — the FHSA, the Home Buyers’ Plan, Alberta’s 30-year amortization option, and the province’s no-land-transfer-tax advantage — that, layered together, could significantly change what’s possible for you.
