New homebuyers can benefit from enhanced GST/HST rebates reducing taxes on new homes. First-time buyers get a full GST refund on homes up to $1 million, with partial refunds up to $1.5 million, valid for contracts signed between March 2025 and 2031. Ontario plans to remove up to 100% of HST on homes up to $1 million for all buyers from April 2026 to March 2027. These rebates can save tens of thousands, but buyers must verify if rebates are included in the purchase price and ensure timely construction delivery to remain eligible.
