FHSA contribution room and growth.

How FHSA contribution room and carry-forward work

Each calendar year you hold an FHSA you earn $8,000 of participation room, starting with the year you open your first account. Unused room carries forward, but only up to $8,000. Your limit in a year is therefore this year’s $8,000 plus up to $8,000 carried forward, to a maximum of $16,000, and never more than the $40,000 lifetime limit in total.

Worked example

You open an FHSA in 2024 and contribute $3,000. You contribute nothing in 2025 or 2026.

In 2026 you can contribute up to $16,000. Lifetime room left is $40,000 − $3,000 = $37,000. The $5,000 that the cap trimmed in 2025 is lost for good, which is why leaving the account empty costs you.

FHSA vs RRSP vs Home Buyers’ Plan

The FHSA and HBP can be used on the same purchase. Sources: CRA, FHSA and CRA, Home Buyers’ Plan (both checked 2026-10-01).

When the account has to close

Your participation period ends on December 31 of the earliest of: the 15th anniversary of opening your first FHSA, the year you turn 71, or the year after your first qualifying withdrawal. Close or transfer the account before then, or the fair market value of what is left is added to your income. A direct transfer to an RRSP or RRIF is tax-deferred.

Contributing too much

Contributions over your room are taxed at 1% per month on the highest excess amount in the month, until you withdraw the excess or it is absorbed by new room. The calculator above flags any excess it finds.

About the FHSA

The First Home Savings Account combines the tax deduction of an RRSP with the tax-free withdrawals of a TFSA when used for a qualifying first home. The balance can be transferred to your RRSP or RRIF on a tax-deferred basis. The account must be closed by the end of the year of the 15th anniversary of opening or the year you turn 71, whichever comes first.

Why the FHSA is structurally better than either account it copies

Every registered account in Canada makes you choose which end of the transaction gets the tax break. An RRSP gives you a deduction going in and taxes the money coming out. A TFSA gives you nothing going in and takes nothing coming out. The FHSA is the only one that does both: deduction on the way in, and nothing owed on the way out when the money buys a qualifying first home.

That is not a marginal advantage, it is a different category of account. For a first-time buyer, a dollar of first-home saving belongs in an FHSA before it belongs anywhere else, and the ordering question (TFSA or RRSP?) that dominates most Canadian savings advice simply does not arise here. There is no version of the comparison in which an account taxed at neither end loses to one taxed at one end.

Open it before you need it. That is the whole trick.

The single most consequential FHSA rule is the one that costs nothing to comply with and cannot be fixed later: contribution room only begins accumulating once the account exists. It does not accrue from the day you turn eighteen the way TFSA room does, and it does not backfill.

So somebody who opens an account with a token deposit and forgets about it is quietly accumulating shelter every year, and somebody who waits until they are house-hunting to open one starts from zero on the day they open it. Given the annual cap and the tight carry-forward, that delay can permanently reduce the total you are ever able to shelter, no matter how much cash you eventually have. If there is a chance you will buy a first home within the next decade, opening the account is the highest-value five minutes in Canadian personal finance.

The deduction is a separate decision from the contribution

This is the most under-used feature of the account and the one that makes it genuinely powerful for someone early in their career. Contributing and claiming the deduction are two different acts, and they do not have to happen in the same year: an unclaimed FHSA deduction can be carried forward and applied against a later year’s income.

Why that matters: a deduction is worth your marginal tax rate, so the same contribution is worth far more against a higher income than a lower one. A student or early-career contributor in a low bracket who claims the deduction immediately converts it at their lowest-ever rate. Holding the claim until a year when income is materially higher can be worth a meaningful multiple of the same contribution: the money is invested and compounding the whole time either way, so the only thing being deferred is the refund, and it comes back larger.

The judgement call is how long to wait. Deferring is only worth it if you are confident income rises, and a refund in hand today has real option value if it is going straight back into the account. The general shape: claim now if you are already at or near your expected long-run bracket, and carry forward if you are clearly at the bottom of an earnings curve.

Two people, two accounts, one house

The FHSA is an individual account, and a couple buying together can each hold one and each make a qualifying withdrawal toward the same home. That doubles the sheltered amount, and it is worth planning around rather than discovering at the offer stage.

It also means the eligibility test is applied to each of you, so a couple where one person previously owned a home is in a different position from a couple where neither did. Check both sides of the test before assuming the plan works, because the answer determines how much of the down payment can come out untaxed.

What happens if you never buy

Nothing bad, which is the reason the account is close to risk-free to open. The balance including all growth can be moved into an RRSP or RRIF on a tax-deferred basis. In effect, money you deducted on the way in stays deducted and simply becomes retirement savings.

The alternative (taking the money out as cash for a non-qualifying purpose) makes the whole amount taxable as income and does not restore the room, so the transfer is almost always the right move if the house does not happen.

The one real constraint is time. The account cannot run indefinitely: the participation period is bounded, and once it ends the balance must be withdrawn or transferred. Diarise the deadline when you open the account, because letting it expire without transferring is the one way to turn a costless option into a taxable event.

How it fits with the rest of the down payment

• FHSA first for first-home money, because it is the only account with a tax break at both ends.
• RRSP Home Buyers’ Plan stacks on top for the same purchase, but it is a loan from yourself that must be repaid to your RRSP on a schedule or added to your income. Where you have a choice, spend the FHSA money first because it never has to be paid back. See the RRSP calculator.
• TFSA is the natural home for anything beyond the FHSA cap, and unlike the FHSA it stays useful if the plan changes. See the TFSA calculator.
• What you invest it in matters more than people think. If the purchase is two years away, market risk is a real problem: a 20% drawdown the quarter before you close is not recoverable on that timeline. A near-term FHSA usually belongs in something predictable; a five-to-ten-year one can carry equity risk.

Then budget for the costs the down payment does not cover: land transfer tax, which in Toronto is charged twice, and the rest of the closing costs. Those come out of cash on closing day and cannot be added to the mortgage. Test what you can actually carry with the affordability calculator before deciding how much of the FHSA to deploy.
