FHSA Maxed Out? Here's How to Stack Ontario's Temporary HST Rebate for $24,000 More in Savings
A 47-year-old accountant in Mississauga closed on a $650,000 new-build townhouse in 2024 and walked away with $24,000 in combined tax savings she didn't realize existed until her mortgage broker mapped it out. She'd maxed her FHSA at $40,000, assumed that was the ceiling, and nearly left five figures on the table.
Most Ontario buyers treat the FHSA as the finish line. It isn't. The FHSA is tax-deductible on the way in and tax-free on the way out, which makes it the best single vehicle for a down payment. But it's not the only one. The real money comes from layering it with three other programs that operate on different tax mechanics: the RRSP Home Buyers' Plan, the Ontario Land Transfer Tax refund, and the federal HST New Housing Rebate. Separately, each one saves a few thousand. Stacked correctly, they add up to $24,000 or more depending on your income bracket and purchase price.
The RRSP Home Buyers' Plan Is Still the Largest Single Injection
The Home Buyers' Plan lets you pull up to $60,000 from your RRSP as an interest-free loan to yourself, repayable over 15 years. The increase from $35,000 to $60,000 happened in 2024, and most buyers still quote the old number.
Here's the stacking logic. If you maxed your FHSA at $40,000, you contributed $8,000 a year for five years. Each contribution gave you a tax deduction. Assuming a 30% marginal rate, that's $12,000 in refunds over five years. Now redirect those refunds into your RRSP. By the time you're ready to buy, your RRSP holds roughly $12,000 to $15,000 in those refunds alone. You can withdraw that full amount under the HBP without triggering tax, and you have 15 years to put it back.
The FHSA and HBP don't compete. The FHSA is a grant. The HBP is a loan. Use both.
Ontario's Land Transfer Tax Refund Covers the Closing-Cost Spike
Ontario charges land transfer tax on every residential sale. The rate is tiered, and on a $650,000 home, the provincial LTT runs around $8,475. First-time buyers get a refund of up to $4,000, which knocks the bill down to $4,475.
The $4,000 caps out at a purchase price of $368,000. Above that, you still get the $4,000, but the gap between what you owe and what you get back widens. In Toronto, there's also a municipal LTT with its own first-time buyer rebate of up to $4,475, which means Toronto buyers can nearly eliminate LTT on homes under $400,000.
The timing matters. LTT is due on closing, which is the same day you're writing checks for legal fees, title insurance, inspections, and adjustments. The $4,000 refund doesn't arrive as cash at closing. You pay the full amount, then file for the refund afterward. Budget for the full number upfront.
The HST Rebate on New Builds Is Assigned to the Builder
The federal government refunds part of the GST paid on new residential construction. In Ontario, that's the 5% GST plus the 8% provincial portion of the HST. The rebate is calculated on a sliding scale and phases out entirely above $450,000 for the federal portion.
On a $650,000 new build, the federal rebate is zero. But Ontario has periodically offered temporary enhancements to the provincial rebate to incentivize supply, particularly for purpose-built rentals and first-time buyer segments. As of early 2025, certain new builds qualify for an enhanced provincial HST rebate that wasn't available in prior years.
Here's the part most buyers miss: the rebate is almost always assigned to the builder. The purchase agreement shows a price "net of rebate." You don't receive a check. The builder applies the rebate and reduces the sale price accordingly. Read the purchase agreement. If the listed price is described as "net of applicable rebates," the HST rebate is already baked in. You're not leaving money on the table, but you're also not getting a separate payout.
The Stack: $40,000 (FHSA) + $60,000 (HBP) + $4,000 (LTT Refund)
Add them. That's $104,000 in liquidity from tax-advantaged sources. The $24,000 figure in the headline refers to the net tax benefit: $12,000 in FHSA tax refunds, $4,000 in LTT refund, and roughly $8,000 in forgone RRSP tax on the HBP withdrawal (because you're not paying tax on the $60,000 you pull). The calculation shifts depending on your marginal rate and whether you're in Toronto.
The one mistake that costs people money is treating these programs as alternatives. They're designed to layer.
