The Basics: Annual and Lifetime Limits
The FHSA has two key limits:
- Annual contribution limit: $8,000 per calendar year
- Lifetime contribution limit: $40,000 total
These limits apply from the moment you open your FHSA. You don't accumulate room before opening the account, so the sooner you open one, the sooner the clock starts.
How Carryforward Works
Unlike TFSAs (which accumulate unused room from age 18), FHSA carryforward only begins after you've opened your account. Here's the rule:
- If you contribute less than $8,000 in a given year, the unused room carries forward to the next year
- You can carry forward a maximum of $8,000 in unused room at any time
- This means the most you can ever contribute in a single year is $16,000 ($8,000 current year + $8,000 carried forward)
A Practical Example
Say you open your FHSA in 2025 but only contribute $3,000 that year.
- Unused room from 2025: $5,000
- 2026 contribution limit: $8,000 + $5,000 = $13,000
But if you didn't contribute at all in 2025 and 2026:
- Unused room cap is still $8,000. You can't stack more than one year's carryforward
- 2027 limit would still be $8,000 + $8,000 = $16,000 max
What Counts as a Contribution
Only cash deposits you make into the account count toward your limit. Transfers from another FHSA (between institutions) don't count. Investment growth inside the account doesn't count either. It's sheltered and doesn't eat into your room.
Over-Contributing Is Penalized
If you exceed your FHSA contribution limit, the CRA charges a 1% per month tax on the excess amount, the same penalty as TFSA over-contributions. Track your contributions carefully, especially if you have FHSA accounts at more than one institution.
When Room Stops Accumulating
Your FHSA closes (and stops accumulating room) when:
- You make a qualifying withdrawal to buy a home
- You reach the 15-year maximum account life
- You turn 71
After that, any unused balance can be transferred to your RRSP without affecting your RRSP contribution room.
Ottawa Context
With Ottawa's average home price in the $650,000+ range, most first-time buyers need every dollar they can get. Maximizing contributions from Day 1, even in smaller amounts, means more tax refunds and more tax-free growth compounding toward that down payment. If you're planning to buy within five years, contributing the full $8,000 each year gets you to the $40,000 lifetime cap exactly on schedule.
Bottom Line
Open your FHSA as early as possible to start accumulating carryforward room. Aim for $8,000 per year, and if you miss a year, use the carryforward the following year. Don't over-contribute, the 1% monthly penalty adds up fast.
