How to Layer Ontario's $56,000 HST Rebate With Your Maxed-Out FHSA
A 29-year-old senior analyst in Kitchener just closed on a $615,000 pre-construction townhouse. Her actual out-of-pocket at closing? Roughly $38,000. She'd maxed her FHSA at $40,000, withdrew $60,000 from her RRSP via the Home Buyers' Plan, and claimed $56,000 in combined HST rebates. That last figure is new. As of 2024, the stacked federal and Ontario HST rebate on qualifying new builds has climbed to $56,000, $32,000 provincial, $24,000 federal, making new construction a structurally better deal than resale for buyers who know how to layer the programs.
Why the HST rebate changed the math
The provincial portion of Ontario's HST rebate jumped from $24,000 to $32,000 in late 2023, part of a short-term push to move new-build inventory. The federal portion stayed at $24,000. Together, they cover most of the 13% HST on homes priced up to roughly $500,000, with partial rebates extending to $650,000. Above that, the rebate phases out entirely by around $825,000.
This matters because the HST rebate is back-end capital. Builders almost always quote prices "net of rebate," meaning the sticker already reflects the $56,000 discount. But if you intend to rent the unit out instead of living in it as your primary residence, you lose the rebate and must pay that amount out-of-pocket at closing. The distinction between owner-occupied and rental intent is a $56,000 tripwire.
The stacking order
Start with the FHSA. Annual limit is $8,000 in 2026, lifetime cap $40,000. Contributions are tax-deductible, withdrawals for a qualifying home purchase are tax-free. That means you get the deduction upfront and pay no tax on the way out, a feature neither RRSPs nor TFSAs offer in combination.
Second layer: the Home Buyers' Plan. You can pull $60,000 from your RRSP tax-free, giving you access to $100,000 in sheltered capital as a single buyer or $200,000 as a couple. The HBP is a loan to yourself, you have five years before mandatory repayments start, then 15 years to pay it back. Miss a year, that portion gets added to your income.
Third: Ontario's Land Transfer Tax rebate, worth up to $4,475. Toronto buyers get an additional municipal LTT rebate of the same amount, stacking to $8,950. This rebate covers the tax on a $368,000 home provincially, higher if you're in Toronto.
Last: the HST rebate itself, which only applies to new construction or substantial renovations. If you're buying resale, this piece vanishes.
What the HST rebate actually covers
On a $600,000 new townhouse, the HST is $78,000. The combined rebate of $56,000 brings that down to $22,000. The builder folds the rebate into the contract price, so you're effectively paying $544,000 plus $22,000 in remaining HST. The $56,000 never appears as a line item you claim; it's embedded.
Where buyers stumble: they assume the builder has handled it, sign the paperwork without reading Schedule B, and discover at closing that they're ineligible because the unit was flagged as an investment property in the agreement. If the HST rebate gets clawed back, you owe the full $56,000.
Timing the tax refund cycle
The FHSA contribution generates a tax refund in the year you contribute. That refund can fund your RRSP, which then feeds your HBP withdrawal. If you're earning $95,000 and contribute $8,000 to your FHSA, you'll get roughly $3,400 back at tax time. Put that into your RRSP, and it becomes part of the $60,000 you can withdraw under the HBP.
This only works if you file on time and plan the contributions across two calendar years. Contribute in January 2026, get the refund in spring 2026, move it to your RRSP before year-end, withdraw under HBP in early 2027. Miss that sequence and the capital sits idle.
The new-build tradeoff
Resale homes don't qualify for the HST rebate, which makes them $56,000 more expensive on a tax-adjusted basis if you're comparing a $600,000 new build to a $600,000 resale. But new builds come with their own risks: construction delays, builder insolvency, occupancy fees before final closing, and Tarion warranty limitations that leave structural defects unaddressed.
The HST rebate tilts the scale toward new construction for buyers who can stomach the closing-date uncertainty. For buyers who need to move in by a fixed date, resale remains the safer bet despite the tax penalty.
