GST on New Homes in Alberta: What You Actually Owe and How to Reduce It

GST adds thousands to the cost of a new home in Alberta — but a rebate program returns a significant portion for most buyers. Understanding how it works before you sign is essential for accurate budgeting.

Builder Prices Usually Include GST — But Not Always

Most Calgary builders advertise prices with GST included (and the rebate already applied). Always confirm in writing which format applies to your specific purchase agreement. A $700,000 listing price means something very different if GST is excluded.

How GST Applies to New Home Purchases

The federal Goods and Services Tax (GST) applies to all new residential construction in Canada, including Alberta. At 5%, this can add a significant amount to the purchase price of a new home. However, a federal rebate program significantly reduces the impact for most buyers — provided you understand the rules and qualify correctly.

This is not a tax that applies to resale homes. When you buy an existing property from an individual seller, GST does not apply. It only comes into play when purchasing from a builder or developer on new construction, substantially renovated homes, or assignment sales of new builds.

The GST/HST New Housing Rebate

To offset the burden of GST on new homes, the federal government created the New Housing Rebate program. Under this program, buyers can recover a portion of the GST paid — up to a maximum of 36% of the GST, capped at $6,300 for homes priced at $350,000 or below. The rebate phases out between $350,000 and $450,000, and disappears entirely above $450,000.

What "GST Included" Actually Means in Builder Pricing

Most Calgary builders advertise prices with GST included, having already applied the rebate. This means the advertised price reflects the net GST cost to you after the rebate. In practice, the transaction works like this:

The Common Builder Approach (Rebate Assigned to Builder)

The builder collects the full 5% GST from you at closing. They then apply for the rebate on your behalf and keep it as part of the purchase arrangement. The advertised price is the all-in price inclusive of this net GST cost. You pay one number and don't deal with the CRA directly for the rebate.

When You Claim the Rebate Yourself

If the builder's price is advertised as "plus GST," you pay full GST at closing and must apply for the rebate yourself through the CRA. This requires filing Form GST190 within two years of possession. Your lawyer should flag this at closing.

Calculating GST on a Real Calgary Purchase

Here is a practical example using a $650,000 new build townhome in SE Calgary:

Example: $650,000 Townhome

Base purchase price (before GST)$650,000
GST at 5%$32,500
Federal GST Rebate (homes over $450K)$0
Total price with GST$682,500

At this price point, the federal rebate does not apply. If the builder advertises $682,500 "all in including GST," the base price was $650,000 and the full $32,500 GST is baked into the price.

Example: $400,000 Condo

Base purchase price (before GST)$400,000
GST at 5%$20,000
Partial Federal GST Rebate (~$2,250 estimate)-$2,250
Net GST cost after rebate~$17,750

The exact rebate amount in the $350K-$450K range follows a linear phase-out formula. Your lawyer or mortgage broker can calculate the precise figure.

Eligibility Conditions for the Rebate

To qualify for the federal GST New Housing Rebate, several conditions must be met:

  • You or a family member must intend to use the home as your primary place of residence
  • The property must be a new or substantially renovated residential building
  • The home must be purchased from a builder, not from a private individual
  • For assignment sales, eligibility depends on the specific transaction structure
  • Investors who intend to rent do not qualify — the rebate is for owner-occupants

Rental Property Investors Do Not Qualify

If you are purchasing a new build as an investment property to rent out, you do not qualify for the standard New Housing Rebate. There is a separate "New Residential Rental Property Rebate" for landlords — the mechanics are similar but the form and process differ. Consult a tax professional before closing.

GST on Upgrades and Add-Ons

GST applies not just to the base price of your home, but also to any upgrades or optional features you purchase through the builder's design centre. This includes flooring upgrades, appliance packages, structural options, and any other items added to your purchase agreement.

This means that a $50,000 upgrade package adds $2,500 in GST to your costs. For homes already above the $450,000 threshold, there is no rebate on this amount. Budget accordingly.

GST on Assignment Sales

Assignment sales — where you buy the rights to a purchase agreement from the original buyer before the home is built — have complex GST treatment. In most cases:

  • The end buyer (assignee) pays GST to the builder at closing on the full purchase price
  • The profit paid to the original buyer (assignor) for assigning the contract may also be subject to GST
  • Whether the assignee can claim the New Housing Rebate depends on their intended use and occupancy
  • The CRA has increased scrutiny on assignment transactions — professional tax advice is strongly recommended

What to Ask Your Lawyer at Closing

When you are preparing for closing on a new build, confirm the following with your real estate lawyer:

1Is the purchase price inclusive or exclusive of GST?
2Has the builder assigned the rebate, or do I need to file for it with the CRA?
3If I need to file, will you prepare and submit Form GST190 on my behalf?
4Have all upgrades had GST applied correctly?
5If this is an assignment, what are the GST implications on both the original price and the assignment premium?

Common Misconceptions

Myth: The GST rebate means I don't pay GST
Fact: You still pay full 5% GST. The rebate is a partial refund — and only applies below $450,000.
Myth: GST doesn't apply if I negotiate it out of the price
Fact: GST is a federal obligation. Builders must collect it. What you can negotiate is whether the price is quoted gross or net of GST.
Myth: The builder handles my rebate automatically
Fact: Many builders assign the rebate to themselves. Confirm explicitly what happens to the rebate in your purchase agreement.
Myth: GST only applies to the base home price
Fact: GST applies to the full transaction: base price + all upgrades and optional add-ons in the purchase agreement.

How GST Fits Into Your Total Budget

For a $600,000 home, GST adds $30,000 to the cost with no federal rebate available. This is real money that must be funded — not included in your mortgage principal in most cases. Use our closing cost calculator to see how GST fits into your full closing cost picture.

Frequently Asked Questions

Do I pay GST when buying a new home in Alberta?+
Yes. All new residential construction in Canada is subject to 5% GST. A partial rebate is available for homes priced under $450,000 if you intend to occupy the home as your primary residence.
Is GST included in the price my builder quoted me?+
Most Calgary builders include GST in their advertised price and have already applied the applicable rebate. Always confirm this in writing — specifically, ask whether the price is "inclusive of all taxes" or "plus GST."
What is the maximum GST rebate on a new home?+
The maximum federal GST New Housing Rebate is $6,300, which applies to homes priced at $350,000 or below. The rebate phases out between $350,000 and $450,000 and is zero above $450,000.
Can I add the GST to my mortgage?+
No. GST must be paid at closing and cannot be rolled into your CMHC-insured or conventional mortgage. It must come from your own funds, similar to your down payment.
Does GST apply to the land portion of my home purchase?+
In most new home transactions, the land is bundled with the home in the total purchase price, and GST applies to the whole amount. However, if you are buying a lot separately to build on, different GST rules may apply.
What happens to GST if my builder goes bankrupt before completion?+
If a builder goes bankrupt, the GST situation depends on whether deposits were held in trust and what assets are available through the insolvency process. Alberta New Home Warranty provides deposit protection up to $100,000 in some circumstances. Always review warranty protection before signing.
