First, what is the HST on a new home?
In Ontario, 5% federal GST and 8% provincial sales tax = 13% HST
On every new primary home built in Canada, federal GST (Good and Services Tax) is charged to the buyer. In some provinces, an additional sales tax is also charged, with those funds going directly to the province.
Ontario is one province (there are others, such as New Brunswick and PEI) that combines the GST and the provincial sales tax into a Harmonized Sales Tax (HST). The entire HST is collected and managed by the federal government through the Canada Revenue Agency (CRA), which then remits the sales tax portion to the province.
In Ontario, the sales tax portion is 8%, which, added to the GST, gives a 13% HST charged on a new home.
First-time buyers could already get a full GST rebate on a newly built home.
Effective from March 2025, the federal Liberal government now allows eligible first-time buyers across Canada to apply for a GST rebate when buying brand-new homes.
Now, the Ontario government wants all buyers of new builds in their province, including first-timers, to save the full HST for a limited time.
How much can you save with the HST rebate?
The new rebate amount you can apply for depends on eligibility and the purchase price of your newly built home:
- Up to $1M – Full 13% HST rebate, maximum rebate of $130,000
- $1M to $1.5M – Flat $130,000 maximum
- $1.5M to $1.85M – Maximum rebate scales down from $130,000 to $24,000
- At or above $1.85M – $24,000 maximum rebate
Isn't there already a GST/HST New Housing Rebate?
Yes, there is a long-standing, pre-existing GST/HST rebate administered by the CRA — and if you've ever filed a GST return, it's a standard line item.
It consists of two components: a federal portion (5% GST) capped at approximately $6,000, and an Ontario portion (8% provincial component of HST) capped at $24,000. But that long-standing rebate also comes with a price cap, so homes above $450,000 receive no meaningful rebate at all.
Compared to the previous rebate, the 2026 rebate expansion, even for a short time, is considered a big deal — offering substantially more savings for buyers of newly built homes.
