The GST/HST New Housing Rebate can apply in Ontario when you’re buying a newly built home from a builder, doing an owner‑built/custom build, or completing a substantial renovation that’s treated as “new housing.” Under the 2026 expansion window, eligibility is broader—this is no longer just for first‑time buyers.
Timing & Claiming: This rebate is typically credited at closing by the builder. If not, buyers can file a rebate application after purchase. RebateMax helps track deadlines to ensure your claim is submitted within allowable windows.
Eligibility Overview: This rebate is generally tied to Ontario new housing scenarios (builder purchase, owner‑built/custom build, or qualifying substantial renovation). For the 2026 expansion window, the rebate is not limited to first‑time buyers—it’s driven by the project/agreement timing and the property’s use (typically a principal residence for the owner‑occupied path). Rental-property claims are handled separately under NRRP.
Instant eligibility confirmation • Ontario new housing rebate expertise
Missed Primary Residence: Failing to occupy the home as your principal residence voids eligibility
Prior Ownership (legacy rules): Under the old program, previous ownership by you or your spouse could disqualify the claim. The enhanced 2026–2027 program is NOT limited to first-time buyers.
Incorrect Property Type: Non-qualifying renovations or property uses may reduce or deny rebates
Incomplete Claims: Missing proper documentation can delay or deny rebate processing
Whether you are taking advantage of the 2026-2027 expansion or filing a retroactive claim, RebateMax structures your file for maximum refund and zero upfront risk.

For a full $130,000 rebate, typical firms take nearly triple what RebateMax charges—while offering limited audit support.
| Feature | Typical Accounting Firms | RebateMax |
|---|---|---|
| Upfront Cost | $2,000 - $5,000 | $0 (Contingency Only) |
| Fee Structure | Flat 15% - 20% | $3,500 flat (Enhanced) or 15% (Legacy) — $0 upfront either way |
| Audit Support | Limited | Full End-to-End Audit Prep |
| Total Fee on $130k Rebate | ~$19,500 | ~$3,500 |
The CRA views major renovations as "New Construction" if you meet specific structural thresholds. We specialize in navigating the 70-90% interior rule and the $90/sqft benchmark. If you have spent over $125,000 on a renovation in Ontario, you are likely sitting on a massive tax refund that your builder or accountant has not fully quantified.


RebateMax is built specifically for Ontario custom homes, luxury builds, and substantial renovations. We are not a generalist accounting firm dabbling in rebates—we live and breathe HST housing legislation so you do not have to.
Result: You keep more of your rebate, file faster, and sleep better knowing your claim is built by specialists.
Q: Do I qualify?
A: If you built a new home, did a substantial renovation (near-total rebuild), or added a major addition in Ontario, you likely qualify. Use the calculator or book a free call and we'll confirm — no obligation.
Q: How much could I get?
A: Up to $130,000 under the enhanced 2026–2027 program (agreements signed Apr 1, 2026 – Mar 31, 2027). Older projects fall under the legacy program (up to $24,000 / $16,080 caps apply).
Q: What does it cost?
A: Nothing upfront. Enhanced program: $3,500 flat fee. Legacy program: 15% of the rebate. We only get paid when you do.
Q: How long does it take?
A: Most files are prepared in 1–2 weeks once we have your documents; CRA processing times vary.
Q: What if CRA audits me?
A: Every file includes full audit support. We handle CRA correspondence start to finish.
Q: Is the enhanced rebate really time-limited?
A: Yes. Agreements must be signed by March 31, 2027. After that, only the legacy program applies.
