The First-Time Home Buyers' GST Rebate lets eligible first-time buyers recover up to $50,000 of the GST on a qualifying new home, with the full rebate on homes up to $1 million and a phased reduction between $1 million and $1.5 million. It became law when Bill C-4 received Royal Assent on March 12, 2026, and generally applies to agreements of purchase and sale with a builder entered into on or after May 27, 2025 and before 2031. In Alberta, where there is no provincial sales tax, the GST is the whole sales tax on a new home, so buyers ask about this rebate early and often.
This is an operational guide for builder teams. It is not tax advice. Eligibility is determined by the Canada Revenue Agency; buyers and builders should rely on CRA guidance and their own advisors.
Key takeaways
- Up to $50,000 of GST can be rebated on a qualifying new home for an eligible first-time buyer.
- Full rebate up to $1 million; the rebate phases out between $1 million and $1.5 million.
- It applies to new homes bought from a builder (and some owner-built homes and co-op shares), not resale homes.
- Agreement dates matter: generally on or after May 27, 2025 and before 2031, with construction starting before 2031 and substantially complete before 2036.
- Builders should give buyers consistent, approved information and route eligibility questions to the buyer's advisor or the CRA.
What does the rebate cover?
According to the Department of Finance announcement and the enacted legislation:
- Amount. Up to $50,000, the GST on a $1 million home.
- Price range. Full relief up to $1 million, reduced linearly to zero at $1.5 million.
- Home types. New homes purchased from a builder, owner-built homes, and shares in co-operative housing corporations.
- Dates. Agreement of purchase and sale on or after May 27, 2025 and before 2031; construction or substantial renovation must begin before 2031 and be substantially completed before 2036.
- Buyer. A first-time home buyer who meets the CRA definition and intends to use the home as a primary residence.
Bill C-4, the Making Life More Affordable for Canadians Act, received Royal Assent on March 12, 2026, which allows the CRA to process claims (Parliament of Canada; MNP).
Why does this matter for Alberta builders?
Alberta has no provincial sales tax, so on a $600,000 new home the federal GST is roughly $30,000 before any rebate. For a first-time buyer that is a material number, and it affects:
- Pricing conversations. Buyers compare homes "after rebate", and sales teams need approved language.
- Agreement dates. Whether an agreement falls on the right side of May 27, 2025 matters, so the signed date must be clear in the file.
- Paperwork. Depending on how the rebate is claimed, the builder may credit it at closing or the buyer may apply to the CRA, and the right forms and declarations must be in the file.
- Status questions. "Did my rebate get applied?" becomes a common question near possession.
How to handle it in buyer operations
- Approve the answers. Write approved answers to the five questions you get most: what the rebate is, the price limits, the date rule, how it is claimed, and who decides eligibility. See buyer status question governance.
- Capture first-time status early. Ask at onboarding whether the buyer believes they qualify, and record it as a buyer statement, not a determination. See the buyer onboarding workflow.
- Record the agreement date and price clearly. These two fields drive the rebate amount.
- Track the rebate documents per buyer. Know which forms and declarations are required for your process and whether each one is signed.
- Confirm treatment at possession. Finance and the lawyers confirm how the rebate appears on the statement of adjustments. Add it to the Alberta possession day checklist.
Which questions need human review and escalation?
- Whether a specific buyer qualifies as a first-time home buyer
- Co-buyers where one person has owned a home before
- Agreements signed near the date threshold, or assignments of an agreement
- Homes priced near or above $1.5 million, or price changes after signing
- Any request to guarantee the rebate amount
The builder can provide information and paperwork. Eligibility belongs to the CRA, and advice belongs to the buyer's lawyer or accountant.
Where Asterisko fits
