How much can I contribute to my FHSA? You can put in $8,000 a year, up to $40,000 in your lifetime — but room only starts in the year you open the account, and only one year of unused room can be carried forward. Someone who opened an FHSA in 2023 and never contributed has $32,000 of room accrued by 2026, but can only contribute $16,000 in 2026.
If you have never opened an FHSA, you have $0 of room. The clock only starts once you open an account.
How much can I contribute to my FHSA?
Choose the year you opened your first FHSA, then press “Calculate my FHSA room”.
This calculator follows CRA’s participation-room formula and assumes no excess FHSA amounts, no withdrawals and no designated amounts. Confirm your exact room in CRA My Account or on your notice of assessment.
How FHSA room is calculated
Your FHSA participation room starts in the year you open your first FHSA. Each year you earn $8,000 of new room, up to a $40,000 lifetime limit. You can also carry forward unused room from the previous year — but only from one year, and at most $8,000.
That is why an FHSA opened in 2023 with no contributions has $32,000 accrued by 2026 (four years at $8,000), but only $16,000 can be contributed in 2026: the current year’s $8,000 plus at most $8,000 carried forward from 2025. An FHSA opened in 2026 has $8,000 of room. If you have never opened an FHSA, you have no room — the clock only starts once you open an account.
This calculator follows the CRA formula: your 2026 room is the smaller of $8,000 plus the room carried forward from 2025, and the lifetime limit of $40,000 minus everything you have already contributed. The room carried forward is the smaller of $8,000 and the unused room you had at the end of 2025.
Assumptions: This calculator assumes you have no excess FHSA amounts, no withdrawals and no designated amounts, and that contributions before 2025 were made in your earliest FHSA years. Confirm your exact room in CRA My Account or on your notice of assessment.
Frequently asked questions
How much can I contribute to my FHSA each year?
$8,000 a year, up to a $40,000 lifetime limit.
Does unused FHSA room carry forward?
Yes, but only from the previous year, and at most $8,000. Unused room from earlier years does not pile up — that is why four years of room accrued since 2023 is $32,000, but only $16,000 can be contributed in 2026.
When does my FHSA room start?
In the year you open your first FHSA. Before that you have no room at all, even if you were eligible earlier.
What is the FHSA lifetime limit?
$40,000. Once you have contributed $40,000 in total, you cannot contribute more, even if you have annual room left.
What if I already used my FHSA to buy a home?
Once you make a qualifying withdrawal to buy a qualifying home, you cannot open another FHSA. This calculator is for people planning their contributions before a purchase.
Methodology and sources
Methodology: Participation room, carry-forward and the $40,000 lifetime limit follow the Canada Revenue Agency (CRA) rules for participating in an FHSA. Room accrues only from the year the first FHSA is opened, at $8,000 a year, with at most $8,000 carried forward from the previous year. The worked examples were checked against CRA’s own examples on its participating in your FHSAs page.
