How to Generate a Tax Deduction Three Months Before You Buy a House
A signed offer on a house due to close in March doesn't mean you missed the FHSA window. The First Home Savings Account has no minimum hold period, you can contribute today and withdraw tomorrow if you have a purchase agreement in hand. Most first-time buyers assume the account is only worth opening if you start years ahead. Wrong.
Here's the structure you're arbitraging: FHSA contributions are tax-deductible like an RRSP, but withdrawals for a qualifying home purchase are tax-free like a TFSA. If you already have a down payment sitting in a non-registered account or a TFSA, routing that money through the FHSA first converts a tax-neutral asset into a tax deduction without losing access to the cash.
The Mechanics
You're allowed to contribute $8,000 per year to an FHSA, with a lifetime cap of $40,000. If you opened the account last year but didn't max it out, unused room carries forward, you can contribute up to $16,000 in a single year if you have $8,000 of carryover from the previous year.
Say you have $30,000 saved in a TFSA and you're closing on a $450,000 townhouse in April. You open an FHSA in November, contribute $8,000 before December 31, and then contribute another $8,000 in January. That's $16,000 total. Your marginal tax rate is 30%. The deduction generates a $4,800 refund when you file in March. You sign the purchase agreement in February, which makes you eligible to withdraw. The FHSA funds move to your lawyer's trust account for closing. The refund lands two weeks later and covers your first property tax installment or the cost of new appliances.
The money was always earmarked for the house. You just ran it through the FHSA on the way there and captured a refund equal to your tax bracket.
What the Carry-Forward Actually Means
The $8,000 annual room only carries forward if the account was open in the previous calendar year. You cannot open an FHSA in 2026 and retroactively claim carryover room from 2023 or 2024. The account has to exist.
If you opened the account in January 2025 but contributed nothing, you now have $16,000 of room available in 2026 ($8,000 from 2025 plus $8,000 for 2026). If you opened it in March 2026, you only have $8,000 of room for 2026. The clock started when the account opened, not when you decided buying a house was imminent.
The TFSA-to-FHSA Pivot
This move works best if you've been saving in a TFSA because withdrawals from a TFSA are always tax-free and don't affect your contribution room for future years. You pull the money out, deposit it into the FHSA, claim the deduction, and still have full access when you need it for the purchase.
It does not work if the money is in an RRSP. Moving RRSP funds into an FHSA counts as a withdrawal, which is taxable income. You'd pay tax on the way out and get a deduction on the way in, a wash at best, a loss if the withdrawal pushes you into a higher bracket.
Contribution Timing
FHSA contributions only count for the calendar year they're made. You cannot contribute in January 2026 and deduct it from your 2025 return. This is different from RRSP rules, which allow contributions in the first 60 days of the new year to count for the prior year.
If you're buying in Q1 of 2026, you need to contribute before December 31, 2025 to get the deduction on your 2025 return. Miss that window and the deduction shifts to 2026, which might still be useful but won't arrive in time to help with immediate post-purchase costs.
Stacking with the Home Buyers' Plan
You can use both the FHSA and the RRSP Home Buyers' Plan for the same purchase. The HBP allows you to withdraw up to $60,000 from your RRSP tax-free, though you must repay it over 15 years. The FHSA withdrawal has no repayment requirement.
A buyer with $20,000 in their FHSA and $40,000 in their RRSP can pull both and use $60,000 for the down payment. The FHSA portion is gone permanently. The RRSP portion has to go back.
The one most people miss is the contribution deadline. December 31. Not tax day.
