Every February, Canadians rush to make RRSP contributions that count for the year that just ended. Many assume the First Home Savings Account works the same way. It does not. The FHSA follows the calendar year, and its deadline is December 31.
This guide covers what the deadline controls, what happens if you miss it, and what to do before the end of the year. The authoritative source is the CRA page Tax deductions for FHSA contributions, which states the rule directly: the FHSA contribution period runs from January 1 to December 31 of the same year.
The short version
- Deadline: December 31. A contribution made by then uses that year's room.
- No 60-day rule. Contributions made in January or February count for the new year, not the previous one. This is the opposite of the RRSP.
- Missing it does not lose the room. Up to $8,000 of unused room carries forward to the next year.
- The deduction is flexible. You can claim it the same year or any later year.
- Room starts when you open the account. Opening before December 31 is the one move you cannot do later for this year.
Why the FHSA is different from the RRSP
The RRSP lets you contribute during the first 60 days of a year and deduct it on the previous year's return. That window exists so you can finish your tax planning once you know your income. The FHSA has no such window. The CRA says it explicitly: contributions made to an FHSA during the first 60 days of the year cannot be deducted on the return for the previous year, unlike contributions to an RRSP.
In practice, the two deadlines for 2026 look like this:
| RRSP | FHSA | |
|---|---|---|
| Last day to contribute for 2026 | March 1, 2027 (first 60 days of 2027) | December 31, 2026 |
| January 2027 contribution counts for | 2026 or 2027 (your choice) | 2027 only |
| Unused room | Carries forward without limit | Up to $8,000 carries forward |
| Deduction timing | Previous year (first 60 days), year of contribution, or later | Year of contribution or later |
The RRSP dates are covered in the RRSP contribution deadline guide.
What the deadline actually controls
The FHSA deadline decides which year's room a contribution uses. It does not decide when you deduct.
Room. Each year your account is open gives you $8,000 of participation room, up to $40,000 over your lifetime. A contribution made on December 30 uses this year's room. The same contribution on January 2 uses next year's.
Deduction. Separately, contributions are deductible in the year you make them or in any later year, and unused deductions can even be carried forward past the account's closure. So a December contribution can be deducted on this year's return, or saved for a year when your income, and therefore your tax rate, is higher.
That second point is why the deadline is less dramatic than it looks. If you contribute $8,000 on January 5, 2027 instead of December 28, 2026, you have not lost the deduction. You simply cannot claim it on your 2026 return. You can claim it on 2027's or later.
What happens if you miss it
If you could have contributed $8,000 in 2026 and did not, up to $8,000 of that unused room carries forward to 2027. In 2027 you could then contribute up to $16,000: the carried-forward $8,000 plus the new $8,000.
Two limits make missing more than one year expensive:
- The carry-forward is capped at $8,000. If you skip both 2026 and 2027, you do not get $24,000 in 2028. You get $16,000. Room above the cap is not lost from your $40,000 lifetime limit, but you can only catch up $8,000 at a time.
- The account has a clock. The FHSA stays open for a limited period (the FHSA rules guide covers the 15-year and age-71 limits). Each year you skip is one fewer year to reach $40,000.
Before December 31: the checklist
- Open the account if you have not yet. Room only starts the year you open your first FHSA. Opening on December 15 with no deposit still gives you $8,000 of room, which carries into next year if you cannot fund it now. Remember to report the opening on Schedule 15 of your return, even with no contribution, so the CRA knows the account exists.
- Count every contribution across every FHSA. Your room is shared across all your FHSAs, at every institution. Add up what you put in this year, plus any transfers from your RRSP to your FHSA, which also use participation room and are not deductible.
- Leave a margin for processing. A transfer initiated on December 31 at one bank may land in January at another. If the deposit is dated next year, it uses next year's room. Fund the account a few business days early.
- Do not overshoot. Going over your room costs 1% per month on the highest excess in the month, until you withdraw it or new room arrives on January 1. The FHSA contribution room calculator shows your room for this year from your opening year.
A note on deductions
Because you can carry the deduction forward, contributing before December 31 and deducting are two separate decisions. A common plan is to contribute every year to keep the room working, and deduct in the years your income is highest. Your FHSA participation room statement, on your notice of assessment or in your CRA account, shows the unused contributions you can still deduct.
Tracking it across accounts
The deadline is simple. The bookkeeping is not, when you hold an FHSA at one institution, an RRSP at another, and move money between them.
In Mozaic, the Contribution Room view (under Analytics) tracks your FHSA room from your opening year and the net amount you have deposited. FHSA contributions are not detected automatically from transactions, so you enter your net deposit and keep it up to date; the view then shows how much room you have left this year, with the $8,000 carry-forward cap applied. It is a tracking aid, not tax advice. Mozaic is free for manual tracking; automatic syncing of your bank and brokerage accounts is $99 CAD a year, and the pricing page has the details.
The bottom line
For the FHSA, think December, not February. Open the account before the year ends, fund it by December 31 if you can, and leave the deduction for whichever year it is worth the most. If you miss the date, the room waits, up to $8,000 at a time.
