How the two rebates work
Which rebate applies depends on when you signed your Agreement of Purchase and Sale.
1. Ontario Enhanced HST Rebate – up to $130,000 (Apr 1, 2026 – Mar 31, 2027)
This temporary program rebates both the 8% Ontario portion and the 5% federal portion of the HST. It applies to all buyers – not just first-time buyers – for a home used as a primary residence or a qualifying long-term rental. The agreement must be signed after March 31, 2026 and before April 1, 2027, construction must begin before January 1, 2029, and the home must be substantially completed before January 1, 2032.
2. Federal First-Time Home Buyers’ GST Rebate – up to $50,000
For agreements signed on or after March 20, 2025 and before 2031, a first-time buyer can recover 100% of the federal GST (the 5% portion) on a new home, up to $50,000:
- Home valued at or below $1,000,000: full rebate, up to $50,000
- Home valued $1.0M-$1.5M: rebate reduced on a straight line (a $1.25M home gets 50% of $50,000 = $25,000)
- Home valued at or above $1.5M: no federal first-time buyer rebate
To qualify you must be 18+, a Canadian citizen or permanent resident, buying your first home as your primary residence, and you (or your spouse/common-law partner) must not have owned and lived in a home in the current calendar year or the previous four. Construction must begin before 2031 and be substantially completed before 2036. This rebate stacks with the existing Ontario New Housing Rebate (75% of the 8% provincial portion, up to $24,000) – so a first-time buyer of a $1M home outside the enhanced window can still save up to about $74,000.
| Scenario | Home Value | Federal | Ontario | Max Total |
|---|---|---|---|---|
| Enhanced (Apr 2026-Mar 2027) | Up to $1.0M | Full 5% | Full 8% | $130,000 |
| Enhanced (Apr 2026-Mar 2027) | $1.0M-$1.5M | included | included | $130,000 max |
| Enhanced (Apr 2026-Mar 2027) | $1.5M-$1.85M | declining | declining | $130K to $24K |
| First-time buyer (standard) | Up to $1.0M | Up to $50,000 | Up to $24,000 | $74,000 |
| First-time buyer (standard) | $1.25M | $25,000 | $24,000 | $49,000 |
| Not first-time (standard) | Over $450K | $0 federal | Up to $24,000 | $24,000 |

Frequently asked questions
Can I claim both the $50,000 federal rebate and the $130,000 Ontario rebate?
Not stacked on the same home. If your agreement falls in the enhanced window (Apr 1, 2026 to Mar 31, 2027), Ontario’s enhanced rebate already covers the full 13% HST (both the 5% federal and 8% provincial), up to $130,000 – that’s the one to use. The federal First-Time Home Buyers’ GST Rebate is for agreements signed before April 1, 2026 (back to March 20, 2025), where it stacks with the standard Ontario rebate of up to $24,000.
Do I have to be a first-time buyer for the $130,000 Ontario rebate?
No. Ontario’s enhanced rebate applies to all buyers of a qualifying new home used as a primary residence or a qualifying long-term rental. The first-time buyer requirement only applies to the separate federal $50,000 GST rebate.
What date makes me eligible for the federal first-time buyer rebate?
Per the Canada Revenue Agency, the agreement of purchase and sale must be entered into on or after March 20, 2025 and before 2031 (for owner-built homes, construction must begin on or after March 20, 2025). The home must be substantially completed before 2036 and be your primary residence.
Does the rebate apply to ICF homes?
Yes – the construction method has no effect on HST rebate eligibility. An ICF home at the same value receives exactly the same rebate as a wood-frame home, and then keeps saving you money on energy for decades. See our ICF 25-Year Energy Savings Calculator.

Quick Facts
- On May 27, 2025, the federal government proposed eliminating the full federal portion of the HST on qualifying newly built and substantially renovated homes valued up to $1 million for first-time home buyers.
- Details of Ontario’s proposed new rebate are based on the federal government’s proposal as announced on May 27, 2025. Implementation of the new Ontario rebate is subject to passage of federal legislation and requires federal regulatory changes. Ontario will continue to monitor the status of the federal proposal as it progresses through the federal legislative process.
- Ontario will work with the federal government to propose that the new Ontario rebate be available if the agreement of purchase and sale for the home is entered into with the builder on or after May 27, 2025, and before 2031. Construction of the home must begin before 2031, and the home must be substantially completed before 2036.
- Other eligibility criteria for the new Ontario rebate would follow those set by the federal government, including that the individual must be acquiring the new home for use as their primary place of residence.
- The Protect Ontario by Building Faster and Smarter Act, 2025, helps speed up the construction of new homes and infrastructure by streamlining development processes and reducing costs, in partnership with municipalities.
