First-Time Home Buyers’ GST Rebate is Law: What Changed and Who Qualifies?
Canada’s first-time home buyers’ GST relief is no longer just a proposal. Bill C-4, the Making Life More Affordable for Canadians Act, received Royal Assent on March 12, 2026. Part 2 amends the Excise Tax Act to create a temporary first-time home buyers’ GST/HST rebate.
In practical terms, the new rebate eliminates the GST for eligible first-time home buyers on qualifying new homes valued at up to $1 million, and phases out relief for qualifying homes valued between $1 million and $1.5 million, to a maximum benefit of $50,000.
What changed from the earlier proposed legislation?
When we first wrote about Bill C-4, it had only passed first reading in the House of Commons. The obvious change is that the rebate is now law. More importantly, there was also a material change to the timing rules. The earlier proposal used May 27, 2025 as the operative start date, while the enacted legislation instead deems the new first-time home buyer provisions to have come into force retroactively on March 20, 2025. That change broadens the pool of potentially eligible transactions.
The final legislation also confirms features that were not fully addressed in our earlier post. It includes a one-rebate-only regime for the claimant and, in some cases, their spouse or common-law partner, and anti-avoidance rules targeting pre-March 20, 2025 agreements that are later varied, assigned, cancelled, or replaced mainly to access the rebate.
Who qualifies as a “first-time home buyer”?
Under the Excise Tax Act, a first-time home buyer must be at least 18 years old and a Canadian citizen or permanent resident at the relevant time. The buyer must also not have occupied, as their primary place of residence, a home they owned — in Canada or elsewhere — during the relevant calendar year or the previous four calendar years. The same general restriction applies where the buyer occupied a home owned by their spouse or common-law partner. Canada Revenue Agency (“CRA”) guidance also states that neither the individual nor their spouse or common-law partner may previously have received the first-time home buyers’ GST/HST rebate.
The relevant testing date for qualifying as a first-time home buyer depends on the transaction type. For a home purchased from a builder, the buyer must qualify when ownership is transferred. For a home on leased land from a builder, the test applies when possession is transferred. For an owner-built or substantially renovated home, the test applies at the earlier of first occupancy or substantial completion. For co-op purchases, it applies when ownership of the share is transferred.
What types of homes are covered?
The rebate is not limited to newly built homes purchased from a builder. The CRA confirms it may apply where an eligible first-time home buyer:
- purchases a newly built or substantially renovated home from a builder;
- purchases a home on leased land from a builder if the lease is at least 20 years or includes an option to buy the land;
- constructs or substantially renovates a home for use as their primary place of residence; or
- purchases a share in a co-operative housing corporation for the right to occupy a newly built or substantially renovated unit.
The CRA also states that certain newly built or substantially renovated mobile homes, modular homes, and floating homes may qualify.
Across all categories, two requirements consistently apply:
- the property must be intended for use as the buyer’s primary place of residence; and
- the buyer must generally be the first person to occupy the home after completion of construction or substantial renovation.
This is clearly a targeted owner-occupier measure, not a general GST break for investors or speculators.
What are the timing requirements?
For homes purchased from a builder, homes on leased land from a builder, and qualifying co-op shares, the agreement of purchase and sale must generally be entered into on or after March 20, 2025 and before 2031. Construction or substantial renovation must begin before 2031, be substantially completed before 2036, and ownership or possession — depending on the structure — must be transferred before 2036.
For owner-built homes, the rule is slightly different. Construction or substantial renovation must begin on or after March 20, 2025 and before 2031, be substantially completed before 2036, and the individual must first occupy the home as a place of residence before 2036. CRA guidance also clarifies that construction begins when actual construction work, such as excavation for the house, starts — not when land is acquired or permits are issued.
How much is the rebate?
For a qualifying new home purchased from a builder, the rebate is up to 100% of the GST (or federal part of the HST) paid, to a maximum of $50,000, where the purchase price is $1 million or less. Where the purchase price is more than $1 million but less than $1.5 million, the rebate is reduced on a straight-line basis. At $1.5 million or more, there is no rebate.
CRA’s example is straightforward: a $1.25 million qualifying home sits at the midpoint of the phase-out range, so the buyer may receive $25,000.
How does the new rebate fit within the existing GST/HST framework?
The new rebate does not replace the existing GST/HST new housing rebate. It operates as an additional rebate for first-time home buyers and, where both apply, functions as a top-up to the existing federal new housing rebate.
That matters because the existing federal new housing rebate phases out between $350,000 and $450,000 and is capped at $6,300, while the new first-time home buyers’ rebate can increase available federal relief to as much as $50,000 for eligible purchasers.
What does this mean in practice?
For Alberta buyers, the headline result is simple: on a qualifying newly built first home priced at up to $1 million, the federal GST can effectively be eliminated; however, the details matter — this is not a blanket rebate for every purchase. It is limited to qualifying new or substantially renovated housing, tied to primary-residence use, subject to first-time buyer rules, and unavailable for transactions that attempt to repackage older pre-March 20, 2025 deals without genuine commercial reasons.
Assessing eligibility requirements is key. The agreement date, construction start date, first occupancy facts, ownership history, and whether the builder will credit the rebate on closing all matter. Even where the new first-time home buyers’ rebate does not apply, purchasers should still consider whether the existing federal GST/HST new housing rebate remains available.
