What is the Bill C-4 First-Time Home Buyers' GST Rebate?
Enacted as part of Bill C-4 (the Making Life More Affordable for Canadians Act) in March 2026, this program provides a full 100% rebate of the 5% federal Goods and Services Tax (GST) paid on the purchase of newly built or substantially renovated homes. The rebate is designed to make new-build housing more accessible to first-time buyers in high-cost urban markets.
Purchase Price Thresholds and Linear Phase-Out Rules?
The GST rebate is fully applicable for newly constructed homes with a purchase price of $1,000,000 or less, resulting in a maximum possible tax savings of $50,000. For homes priced between $1,000,000 and $1,500,000, the rebate phases out on a linear sliding scale (dropping by 10% for every $50,000 increase in price). Homes priced at $1,500,000 or more are completely ineligible for the rebate.
Stacking the GST Rebate with the Home Buyers' Plan (HBP)?
First-time buyers can amplify their purchasing power by combining the new GST rebate with the federal Home Buyers' Plan. Under the updated HBP rules, individuals can withdraw up to $60,000 (and couples up to $120,000) from their Registered Retirement Savings Plan (RRSP) tax-free. By avoiding immediate withholding taxes on these withdrawals, buyers can save thousands of additional dollars for their down payment.
