Split retirement income between spouses to legally reduce your combined tax bill — one of Canada's best retirement planning strategies
A Spousal RRSP is one of the most powerful — and most underused — tax strategies available to Canadian couples. By directing RRSP contributions to a lower-income spouse's plan, you can equalize retirement income between two people, potentially saving thousands of dollars in taxes every year during retirement. The higher-earning contributor still claims the deduction; the lower-income spouse owns the account and pays tax on withdrawals at a lower rate.
A Spousal RRSP is simply an RRSP account owned by one spouse (the "annuitant") but contributed to by the other spouse (the "contributor"). Here are the key mechanics:
The most important rule in Spousal RRSP planning is the 3-year attribution rule. If the annuitant withdraws money from the Spousal RRSP within 3 calendar years of the last spousal contribution, the withdrawal is "attributed back" to the contributor and taxed in the contributor's hands — not the annuitant's.
The clock is based on calendar years, not 36 months. A contribution in December 2025 means the 3-year rule expires on January 1, 2029 (beginning of 2026 = year 1, 2027 = year 2, 2028 = year 3, 2029 = free).
The 3-year attribution rule does not apply in the following situations:
The Spousal RRSP strategy is most valuable in these situations:
| Situation | Benefit |
|---|---|
| One spouse earns significantly more than the other | High income difference = large marginal rate difference = large tax savings |
| One spouse is not working or has interrupted career | Stay-at-home parent builds retirement savings in their own name |
| One spouse has a defined benefit pension | Spouse with pension shifts RRSP savings to partner to equalize retirement income |
| Both spouses expect different retirement ages | Earlier-retiring spouse can draw from Spousal RRSP at lower rates while still young |
| Self-employed vs. employee couple | Self-employed spouse often has higher income variability; Spousal RRSP smooths income |
Since 2007, eligible pension income (including RRIF withdrawals from age 65+) can be split between spouses on the tax return. This raised the question: do you still need a Spousal RRSP?
The answer is yes, for several reasons:
The RRSP must be closed by December 31 of the year the annuitant turns 71 — not the contributor's age. This creates a planning opportunity:
If a 72-year-old high earner has a 65-year-old spouse, the older spouse can continue contributing to the younger spouse's Spousal RRSP until the younger spouse turns 71 — as long as the contributor has unused RRSP room and earned income. This can extend the RRSP contribution window by several years.
Opening a Spousal RRSP is straightforward:
Start building your retirement savings with KOHO's high-interest savings. New users get $100 with code 45ET55JSYA.
Get $100 with KOHO →Yes. Common-law partners (living together for 12+ months or with a child together) have the same Spousal RRSP rights as married couples.
In the event of separation, attribution rules stop applying. The Spousal RRSP is typically divided as part of the matrimonial property settlement using Form T2220 for a tax-free rollover between spouses.
Yes. You can split your RRSP room between your own RRSP and your spouse's RRSP in any combination. The total cannot exceed your personal contribution room.
No minimum age. A very young spouse can hold a Spousal RRSP and accumulate decades of tax-sheltered growth.
