FHSA Maxed Out? How to Layer Ontario's HST Rebate With Federal Programs for Six-Figure Savings
A 29-year-old software developer in Brampton just closed on a $720,000 pre-construction townhome. She maxed out her FHSA at $40,000, pulled $35,000 from her RRSP under the Home Buyers' Plan, and walked into closing with $24,000 less in HST to settle because of rebates most buyers don't layer correctly. The difference between her outcome and the median buyer's isn't effort. It's sequencing.
The FHSA Runs Out Fast
The FHSA allows $8,000 in annual contributions and caps at $40,000 lifetime. For anyone who opened the account when it launched in 2023, the runway is already half gone. Contributions are tax-deductible, withdrawals for a qualifying home purchase are tax-free, and you don't repay what you take out. That makes it strictly better than the RRSP Home Buyers' Plan, which now allows $60,000 withdrawals but requires you to repay every dollar over 15 years starting two years after the withdrawal.
Once the FHSA is exhausted, most buyers assume the next dollar goes into the RRSP. Wrong sequencing. The next move is to confirm whether you're buying new construction or resale, because the tax treatment splits hard at that line.
New Construction Changes the Math
Resale homes in Ontario trigger provincial land transfer tax. First-time buyers get a $4,000 refund, which sounds meaningful until you realize the LTT on a $720,000 home is roughly $10,475. You're paying $6,475 out of pocket. In Toronto, add municipal LTT of another $10,475, partially offset by a $4,475 municipal rebate. The refunds don't scale with price.
New construction doesn't trigger LTT. It triggers HST at 13%, and that's where the leverage sits. On a $720,000 new-build, the HST is $93,600. Builders usually roll that into the purchase price, but the rebate structure is what matters. The federal portion rebates up to 36% of the 5% GST on homes under $450,000, phasing out completely at $550,000. For most GTA buyers, the federal rebate is零 or negligible.
The provincial portion rebates up to 75% of the 8% Ontario HST, capped at $24,000, and critically does not phase out at the same threshold as the federal side. On a $720,000 home, you're eligible for the full $24,000 provincial rebate if the home is your principal residence. That rebate gets assigned to the builder at closing, reducing what you owe. If you buy the home as an investment property, you pay the full HST upfront and apply for the New Residential Rental Property Rebate later, a different structure, worse timing.
How the Stack Works
Start with the FHSA. $40,000 contributions generate roughly $10,000-$12,000 in tax refunds at Ontario's marginal rates for someone earning $85,000-$95,000. Use those refunds to fund the next year's FHSA or cover closing costs.
Next, the HBP. Pull $60,000 from your RRSP. You don't pay tax on the withdrawal, but you must repay $4,000 annually starting in year two. Miss a payment and CRA treats it as income. The HBP is a forced savings plan with a repayment gun pointed at your future cash flow.
Then the provincial HST rebate. On new construction, that's $24,000 off the closing bill, no repayment, no income test.
Add the Ontario LTT refund if you're buying resale instead. $4,000. Not huge, but it's $4,000 you don't leave on the table.
Total: $40,000 (FHSA) + $60,000 (HBP) + $24,000 (HST rebate, new construction) = $124,000 in deployed capital and rebates. The six-figure claim in the title isn't about total savings, it's about liquidity retained or rebates captured that most buyers either don't know exist or don't combine.
Where Buyers Lose the Thread
The most common miss is buying new construction without confirming the rebate assignment. Builders sometimes keep the rebate themselves and adjust the purchase price accordingly. If the Agreement of Purchase and Sale doesn't explicitly assign the rebate to you, you're paying full freight. Read the APS. Confirm the line item.
Second miss: pulling from the RRSP before maxing the FHSA. The FHSA is the better deal on every dimension except contribution room. Use it first.
Third: treating the HBP withdrawal as free money. It's a loan from your future retirement account. The opportunity cost is 15 years of compound growth on $60,000. At 6% real return, that's roughly $84,000 you're not building. The HBP makes sense when liquidity is the binding constraint. It does not make sense as a default.
