The headline number is only the beginning
Canada Revenue Agency's October 2026 memorandum explains an important tax benefit for eligible first-time purchasers of newly constructed or substantially renovated homes. In combination with existing new-housing rebate rules where applicable, the First-time Home Buyers' GST/HST rebate can eliminate the GST or federal HST component on an eligible new home valued up to $1 million. Relief decreases when the value is between $1 million and $1.5 million, and no FTHB GST/HST rebate is available at or above $1.5 million. It is not a blanket refund on every Canadian property sale or an automatic grant to every purchaser.
New housing is not the same as any first home
A central eligibility issue is what is being purchased. The CRA's programme is directed at qualifying newly built or substantially renovated properties, including some builder purchases and owner-built situations. Buying an ordinary resale home does not automatically bring the purchase within the FTHB tax rebate scheme. Nor does putting a first-time buyer's name on a contract guarantee relief if the ownership, occupancy or construction rules are not satisfied. The property is generally required to be intended as a primary place of residence and the applicant must satisfy the relevant first-time buyer criteria.
The agreement date and build timeline matter
The CRA's eligibility guidance states that, for a qualifying purchase from a builder, the purchase-and-sale agreement generally must have been entered into on or after March 20, 2025, and before 2031. It also lists construction or substantial-renovation timing and transfer or occupancy deadlines, including completion before 2036 in specified cases. Different housing structures, such as owner-built homes or purchases involving leased land, follow distinct technical rules. A buyer should check the category that actually matches the transaction instead of copying dates from another type of deal or an online calculator.
What happens above $1 million
For an eligible property at or below $1 million, the CRA describes full relief on the federal GST/HST portion through the combined applicable rebate mechanism. Between $1 million and $1.5 million the first-time-buyer rebate phases down, rather than falling away at the first dollar above $1 million. At $1.5 million or higher that particular rebate is unavailable. This is a description of federal tax relief, not a promise to refund the entire purchase cost, land-transfer tax, mortgage interest, legal fees or provincial taxes in every jurisdiction. Ontario has an additional enhanced rebate framework with its own rules.
Who counts as a first-time buyer?
The CRA looks beyond a marketing label. The qualifying person's prior homeownership and occupancy circumstances, together with those of a spouse or common-law partner where applicable, can affect eligibility. Official conditions also restrict repeated use of the first-time-buyer GST/HST rebate. A person who qualifies for some other housing assistance is not necessarily eligible for this tax programme. Buyers should review the CRA's precise first-time buyer definition, intended principal-residence use, contract timing and documentation before signing a deal based on an assumed tax saving.
How to avoid a costly contract misunderstanding
Ask the builder or lawyer whether the advertised price includes GST/HST, whether a rebate is assigned to the builder in the sale agreement and which party is responsible if CRA later denies the application. Confirm the net purchase price and any tax collected with a written breakdown. If buying a new condominium, check whether the unit's construction and first-occupancy details meet the rules. Ask what documentation is required for the application. A responsible estimate uses the final eligible value, province and transaction type, and distinguishes federal relief from a separate provincial programme.
Frequently asked questions about the 2026 rules
Is an existing resale home automatically covered? No. Does the federal first-time-buyer rebate cover properties worth $2 million? No: the CRA's specified FTHB rebate ends at $1.5 million. Is it guaranteed to every buyer under $1 million? No, other eligibility criteria apply. Can some Ontario purchasers receive additional relief? Potentially, subject to the CRA's published provincial framework. The primary reference is the October 2026 memorandum, backed by the CRA's detailed eligibility guide.
