GST Rebate on New Homes in Alberta: The 2025 First-Time Buyer Exemption Explained

New construction in Alberta has always come with a cost that resale properties don't: the 5% federal Goods and Services Tax. On a $600,000 new build, that's $30,000 in additional cost that doesn't apply to a comparably priced resale home. For years, the GST rebate designed to offset this was so limited it was functionally useless for most Calgary and Edmonton buyers.

That changed with the 2025 reform. First-time buyers who signed purchase agreements on or after March 20, 2025 can now access a full GST rebate on new homes up to $1 million — eliminating the tax entirely for the vast majority of new construction transactions in Alberta.

The Old Rebate: Why It Stopped Working

The original GST New Housing Rebate was introduced decades ago with price thresholds that were never updated for inflation. Under that structure:

• Homes under $350,000: 36% of GST paid, capped at $6,300
• Homes between $350,000 and $450,000: a tapering rebate
• Homes at or above $450,000: zero rebate

In 2010, the $450,000 threshold made some sense. By 2024, the average new home in Calgary was well above $600,000 and most Edmonton new builds weren't far behind. The $450,000 ceiling had rendered the rebate inaccessible to virtually every buyer in either city's new construction market.

The 2025 Reform: Full Rebate Up to $1 Million

The federal First-Time Home Buyers' GST/HST Rebate, which took effect March 20, 2025, fundamentally restructured the program. For eligible first-time buyers:

• New homes valued up to $1,000,000: Full rebate of the 5% GST paid, up to a maximum of $50,000
• New homes valued between $1,000,000 and $1,500,000: Partial rebate that phases out proportionally
• New homes above $1,500,000: No rebate

In Alberta, where there is no Provincial Sales Tax or HST, the only consumption tax on new construction is the 5% GST. The rebate eliminates this entirely for most buyers.

The financial impact:

For the typical Alberta first-time buyer purchasing a new townhome or entry-level detached house in the $450,000 to $750,000 range, the reform means zero GST on the purchase.

Who Qualifies

The eligibility rules for the 2025 rebate are tied to the federal definition of first-time buyer, which is the same four-year lookback test used for the FHSA:

• You have not owned a home that you occupied as a principal residence at any time during the current calendar year or the preceding four calendar years
• If you have a spouse or common-law partner, the same test applies to them

Note: If you are purchasing with a co-buyer who is not a first-time buyer by this definition, the rebate is unavailable, even if you personally qualify. Both purchasers must meet the first-time buyer test.

Additional conditions:

• The home must be your primary residence — not a rental, cottage, or investment property
• You must be a Canadian resident for tax purposes
• The purchase agreement must have been signed on or after March 20, 2025

How the Rebate Is Applied

In most new construction purchases, the builder applies for the rebate on the buyer's behalf and assigns the rebate to the sale transaction. This means the purchase price you pay is already net of the GST rebate — the rebate is credited directly against your closing costs rather than received as a separate cheque after the fact.

Your purchase contract should specify whether the stated purchase price is GST-inclusive or GST-exclusive. New home builders typically advertise prices as "plus applicable taxes" — the rebate then comes off those taxes. Confirm with your builder's sales team exactly how the GST and rebate are reflected in your agreement of purchase and sale.

If you meet the eligibility criteria but the builder does not apply the rebate, you can claim it directly through the CRA using Form GST191 after closing. Keep all documentation of the purchase, your residency, and your first-time buyer status.

Alberta's Advantage Over Other Provinces

Alberta buyers receive a meaningfully larger benefit from this rebate than buyers in Ontario, BC, or the Maritime provinces — because Alberta has no Provincial Sales Tax. In provinces with HST (Ontario, Nova Scotia, etc.), the combined federal and provincial tax rate on new homes is 13% to 15%. While those provinces have their own rebate structures, the complexity of tracking federal versus provincial components adds complications.

In Alberta, the calculation is clean: 5% GST, rebated in full for eligible buyers on purchases up to $1 million. There is no provincial layer to navigate.

Stacking with CMHC Eco Plus

If your new home qualifies for energy efficiency certification (Built Green, ENERGY STAR, or a home with solar), you can also claim the CMHC Eco Plus premium refund on top of the GST rebate. The Eco Plus program refunds 25% of your CMHC mortgage insurance premium — on a $450,000 purchase with a $18,000 CMHC premium, that's $4,500 back.

The GST rebate and Eco Plus are separate programs with separate eligibility requirements, but both can be claimed on the same purchase. Combined, they can reduce your total cost of entry on an energy-efficient new build by more than $25,000.

What This Means for Your Purchase Decision

Before the 2025 reform, a first-time buyer comparing a $550,000 resale condo to a $550,000 new build faced a $27,500 GST penalty on the new build — effectively making it $577,500 in real terms. That gap distorted purchase decisions toward resale.

With the rebate in place, that distortion disappears for eligible buyers. The new build's warranty coverage (the 1-2-5-10 protection), modern building envelope performance, and lower expected maintenance costs in the first decade become genuine competitive advantages rather than factors offset by a tax penalty.
