7 FHSA mistakes that cost first-time buyers real money

Mistake #1: Waiting to open the account

Unlike a TFSA, FHSA contribution room does not accumulate in the background before you have an account. Room only starts building the calendar year you open your first FHSA, based on the annual limit set when the program launched in 2023 (confirm the current-year figure with the CRA). Someone who waits three extra years to open an FHSA doesn't get to backdate that room — it's simply gone.

The fix is almost free: if you're even loosely thinking about owning a home someday, open an FHSA now, even with a token deposit. The clock starts the moment the account exists, not the moment you're ready to save seriously.

Mistake #2: Treating the contribution deadline like an RRSP

RRSPs give you a grace period into the first 60 days of the following year to make a contribution count for the prior tax year. The FHSA does not work that way — contributions only count for the calendar year they're actually made, so the real deadline is December 31.

Buyers who are used to the RRSP rhythm sometimes try to "catch up" for last year in February or March and find out the deposit only counts going forward. If you want a given tax year's deduction, the money needs to be in the account before the ball drops on New Year's Eve.

Mistake #3: Assuming any withdrawal is automatically tax-free

The tax-free treatment only applies to a "qualifying withdrawal," and the CRA's conditions are specific: you generally need a written agreement to buy or build a qualifying home, you must still meet the first-time buyer test at the time of withdrawal, and you must intend to use the home as your principal residence within about a year.

• Withdraw before you have an accepted offer, or for a home that doesn't qualify, and the money can come out fully taxable instead of tax-free. - "First-time buyer" for FHSA purposes generally means you (or your spouse/partner) haven't owned and lived in a home as a principal residence in the current year or the prior four calendar years — so someone who owned a home six years ago may still qualify. - Paperwork order matters: line up the purchase agreement before you touch the account.

Mistake #4: Not knowing what happens if the home purchase falls through

Plans change — deals collapse, life happens, someone decides to keep renting. If you never make a qualifying withdrawal, the FHSA doesn't just sit there as dead money. You can transfer the balance to an RRSP or RRIF tax-free without using up any RRSP contribution room, or take a regular withdrawal that gets added to your taxable income for the year.

The mistake is not planning for this branch at all, and either panic-withdrawing (creating a tax bill) or leaving the account open indefinitely without a decision as the account's time limit approaches.

Mistake #5: Ignoring the account's shelf life

An FHSA has to be collapsed within about 15 years of being opened, or by the end of the year you turn 71, whichever comes first (confirm exact mechanics with the CRA, since this is a structural rule worth double-checking against your own situation). That deadline can sneak up on someone who opened the account young, didn't buy for over a decade, and never revisited it.

Set a calendar reminder well before the deadline so you have time to either complete a qualifying withdrawal or move the balance to an RRSP/RRIF on your own terms rather than by default.

Mistake #6: Misusing the RRSP-to-FHSA transfer

You can move money from an existing RRSP into an FHSA without triggering immediate tax, and it counts against your FHSA lifetime limit. The mistake is expecting a second deduction for money that already got one inside the RRSP — a transfer isn't a new contribution, so it isn't deductible again, and it doesn't restore the RRSP room you used. Treat it as a repositioning move, not a way to double-dip.

Mistake #7: Forgetting each partner needs their own account

There's no joint FHSA. If you and a partner are both genuinely first-time buyers, you can each open an account and each get your own annual and lifetime limits — effectively doubling the tax-free pool toward one home. Couples who assume one account covers the household, or who let only one partner open an FHSA out of convenience, leave real contribution room and deduction value on the table.
