Spousal RRSP
REER de conjoint in French
Quick definition
A spousal RRSP is a retirement account owned by your spouse or common-law partner but funded with your money and your contribution room. You claim the deduction now at your rate; your spouse pays the tax on withdrawals later, usually at a lower rate.
How a spousal RRSP works
A spousal RRSP flips the usual RRSP setup. You make the contribution and claim the deduction on your own return, at your own marginal tax rate. But the account belongs to your spouse or common-law partner: they own it, they control the investments, and when the money comes out in retirement it is taxed in their hands, at their rate.
That last part is the whole point. If you earn much more than your spouse, you get a deduction at a high rate today, and the eventual withdrawals are taxed at your spouse's lower rate. The gap between those two rates is pure tax savings, and it makes the spousal RRSP one of the few fully sanctioned retirement income-splitting tools in the Canadian tax system.
One rule people constantly get backwards: a spousal RRSP uses your contribution room, not your spouse's. Your combined contributions to your own RRSP and to any spousal RRSP cannot exceed your personal room. Your spouse's room is untouched, and they can still contribute fully to their own RRSP on top. You can open a spousal RRSP at any bank, credit union or brokerage that offers regular RRSPs; the paperwork simply names one spouse as the owner and the other as the contributor.
The 3-year attribution rule: the trap
Here is the rule that catches people. If your spouse withdraws from the spousal RRSP in the calendar year of any spousal contribution, or in either of the two following calendar years, the withdrawal is taxed in your hands, not theirs, up to the amount you contributed in that window. The CRA calls this attribution, and it exists precisely to stop couples from cycling money through the lower-income spouse for a quick tax break. The rule looks at your contributions to any spousal RRSP for that spouse, not just the specific account the withdrawal came from, and anything withdrawn above the recent contributions is still taxed to your spouse.
Two practical consequences follow. First, any new contribution restarts the clock on the amounts involved, so if withdrawals are coming, stop contributing well ahead of time. Second, because the rule counts calendar years rather than months, December contributions shorten the wait by nearly a year. Contribute in December 2026 and the money clears attribution on January 1, 2029, barely more than two years later. Contribute the same amount in January 2026 and you wait for the same date, almost three full years.
Who actually benefits
Spousal RRSPs shine for couples with a big income gap who plan to retire before 65. Since 2007, pension income splitting lets you shift up to 50% of RRIF and similar pension income to your spouse once you are 65, which does much of the same job automatically. Before 65, that tool is largely unavailable, and the spousal RRSP is the main way to get retirement income taxed in the lower-income spouse's hands. It also splits 100% of the money you direct to it, not just 50%. The end goal is two similar-sized retirement incomes taxed in two sets of low brackets instead of one large income taxed in high brackets.
A little-known planning point: contributions are allowed until the end of the year your spouse turns 71, even if you are already past 71 and your own RRSP has been converted or closed. An older contributor with leftover room, or new room from working income, can keep deducting contributions for years by directing them to a younger spouse's plan.
On separation or divorce, the attribution rule generally stops applying once you are living apart because of the breakdown, and the account simply stays with the spouse who owns it.
In Canada
Common-law partners who meet the tax definition (generally 12 months of continuous cohabitation, or a shared child) can use spousal RRSPs exactly like married couples, and the rules are the same in every province, including Quebec. Contributions made in the first 60 days of a year can be deducted on the previous year's return, just like regular RRSP contributions, but watch the interaction with attribution: the deduction year and the calendar year of the contribution are not the same thing, and attribution runs off the calendar year. Contribution receipts for spousal plans identify both the contributor and the owner, which is how the CRA applies the attribution rule, so keep the paperwork straight.
Worked example
Priya earns $120,000 in Ontario; her spouse Sam expects about $40,000 of retirement income. At those incomes (as of July 2026), Priya's marginal rate is about 43.4% and Sam's is about 19.05%. Priya contributes $10,000 to a spousal RRSP in Sam's name, using $10,000 of her own room, and saves about $4,341 in tax right away. Years later, past the attribution window, Sam withdraws that $10,000 and pays about $1,905. The same dollars taxed at Sam's rate instead of Priya's leave the couple roughly $2,436 ahead, before counting decades of tax-deferred growth on the full amount.
