Ontario HST New Housing Rebate
Already in list priceIn Price
The provincial portion of HST (8%), refunded up to $24,000 on new homes priced above $400,000. Already deducted from the MLS list price by the builder.
Proposed 13% HST Rebate
Pending federal approvalAdditional
If the proposed 13% HST rebate passes, additional savings on top of the $24k Ontario rebate already in the list price.
Total Combined HST Relief
Existing + proposedCombined
The total HST relief available on a qualifying new build — what's already in the price plus what could be added if the FTHB rebate passes.
How HST rebates work on new builds
The existing $24,000 Ontario HST New Housing Rebate (provincial portion, capped at $24k for homes above $400k) is already deducted from the MLS list price by the builder. You don't claim it separately — it's baked in.
The proposed 13% HST Rebate would refund the FULL 13% HST on qualifying new builds under $1 million for eligible buyers — that figure includes the $24k Ontario portion plus the remaining federal portion.
The "Additional" amount above is the extra savings beyond what's already in your price — calculated as list price − (list + $24,000) ÷ 1.13. The rebate has not yet been passed into law. Final eligibility and effective date are subject to change.
Eligibility Logic
The proposed rebate applies to qualifying new builds under $1 million purchased as a primary residence. Final eligibility rules are still pending.
Filing Strategy
The Ontario portion is typically claimed by the builder and assigned at closing. For the proposed 13% rebate (if passed), expect a separate claim form at closing — your lawyer will guide the paperwork.
Real-World Impact
On a $650k new build, the proposed 13% HST rebate would save buyers an additional ~$53,500 beyond the $24k Ontario rebate. Combined relief approaches $77,500 — significant on any new home purchase.
