The RRSP’s “first 60 days” rule, which lets a contribution made early in the year be deducted on the previous year’s return, has no FHSA equivalent. An FHSA contribution made in January or February counts for the year it is made. What the FHSA does have is flexibility on the other side: you can hold the deduction and claim it in a later year. This page covers both. For the rest of the account’s rules, see the FHSA guide and the FHSA guides directory.
What the RRSP rule does
RRSP contributions made in the first 60 days of a calendar year can be deducted on either that year’s return or the previous year’s. That window lets a January or February RRSP contribution still lower the tax on the year just ended.
The FHSA has no lookback
FHSA contributions are tied to the calendar year in which they are made:
| Contribution made on | Can be deducted on |
|---|---|
| January 5 | That year’s return, or a later year’s |
| February 28 | That year’s return, or a later year’s |
| December 31 | That year’s return, or a later year’s |
| RRSP | FHSA | |
|---|---|---|
| Early-year contribution counts for the prior year | Yes, within the first 60 days | No |
| Contribution deadline for a year | About 60 days into the next year | December 31 |
| Deduction can be carried to a later year | Yes | Yes |
| New room | Based on the prior year’s earned income | $8,000 on January 1, after the year you open your first FHSA |
So if the goal is to lower the tax on a year that has already ended, only an RRSP contribution in the 60-day window does that. An FHSA contribution made in the same weeks lowers the current year’s tax instead, or a later year’s if you defer it.
Deferring the FHSA deduction
CRA’s rules for the deduction:
- A contribution can be deducted for the year it is made or a later year.
- Contributions you don't deduct carry forward, even after your FHSAs are closed.
- A contribution made in the first 60 days of a year can't be deducted for the year before, unlike an RRSP contribution.
- The deduction is limited to your annual FHSA limits for the year and earlier years, less deductions already claimed.
- Lifetime FHSA deductions can't exceed $40,000, and transfers from your RRSPs reduce that amount.
- Transfers from your RRSPs can't be deducted.
- Contributions made after your first qualifying withdrawal can't be deducted for any year.
- An excess amount you remove as a designated withdrawal can't be deducted for any year.
You don’t have to claim an FHSA contribution in the year you make it, which lets you contribute now, so the money starts growing tax-free, and claim the deduction when it is worth more.
Example.
| Year | Income | Contribution | Deduction claimed |
|---|---|---|---|
| 1 | Lower (26% marginal rate) | $8,000 | None; carried forward |
| 2 | Similar | None | None |
| 3 | Higher (33% marginal rate) | None | $8,000 from year 1 |
Claimed in year 3, the deduction saves about $2,640 instead of about $2,080 in year 1, a difference of about $560. The contribution itself still counts toward year 1’s room.
Deferral suits someone whose income is about to rise: a student, someone on parental leave, or a newcomer in a first partial year. Where the deduction and contributions are reported is summarised in the FHSA guide.
When to contribute during the year
With no prior-year window, the timing within the year is about investment growth and cash flow:
| Approach | Timing | Trade-off |
|---|---|---|
| Lump sum early | January, once new room is available | Longest time invested |
| Monthly | About $667 a month for the full $8,000 | Spreads the cash flow |
| Late in the year | By December 31 | Suits a year-end bonus; less time invested |
When new room arrives
In the year you open your first FHSA you get the full $8,000, with no proration by month. In each later year you get another $8,000, plus any unused room carried forward (capped at $8,000), subject to the $40,000 lifetime limit. How that cap plays out over several years is on FHSA carry-forward rules; the limits themselves are on FHSA contribution limit.
