How it works
A spousal RRSP is an ordinary RRSP owned by one spouse (the annuitant) that the other spouse (the contributor) pays into. Three rules define it:
- The contributor’s room is used. Contributions count against the contributor’s RRSP deduction limit, not the annuitant’s. A $10,000 spousal contribution leaves the contributor with $10,000 less room for their own plan.
- The contributor takes the deduction. The tax saving lands on the higher earner’s return at the higher marginal rate.
- The annuitant owns the money. Withdrawals are the annuitant’s income and are taxed at the annuitant’s rate, subject to the attribution rule below. The annuitant also controls the investments and can withdraw at any time.
The deadline, the 60-day rule and the $2,000 over-contribution cushion all apply exactly as for a personal RRSP, because they are the contributor’s limits.
Worked example
Priya earns $150,000 in Ontario and her partner Sam earns $30,000. Priya contributes $15,000 to a spousal RRSP for Sam and deducts it, saving about $6,500 at her 43.4% marginal rate. Decades later, Sam withdraws that money in retirement at roughly 20%, paying about $3,000 in tax on $15,000. Had Priya kept the money in her own RRSP and withdrawn it herself in a 30% retirement bracket, the tax would have been $4,500.
The three-year attribution rule
If the annuitant withdraws from any spousal RRSP and the contributor made a spousal contribution in the year of the withdrawal or either of the two preceding calendar years, the withdrawal is taxed to the contributor, up to the total of those contributions. The excess, if any, is taxed to the annuitant.
The rule is measured in calendar years, not months. A contribution made on December 31, 2026 blocks clean withdrawals in 2026, 2027 and 2028; a withdrawal on January 2, 2029 is fine. Contributing on January 1 instead of December 31 costs a full extra year of waiting.
Show the math
Attributed amount = min(withdrawal, spousal contributions made by the contributor in the withdrawal year and the two prior calendar years). The contributor reports it on their return; the annuitant reports only the remainder. The rule is applied on form T2205. Exceptions: RRIF minimum amounts, withdrawals while the spouses are living apart because of a breakdown of the relationship, withdrawals after the contributor’s death, and withdrawals while the annuitant is a non-resident. Withholding is still applied to the annuitant’s withdrawal regardless of attribution.
Where it still beats pension splitting
Since 2007, spouses aged 65 and over can allocate up to 50% of RRIF and pension income to each other on the tax return, which achieves most of what the spousal RRSP was invented for. Three cases remain where the spousal RRSP is better:
- Withdrawals before 65. Pension splitting of RRIF income only starts at 65. A couple retiring at 58 who want the low earner to draw first need a spousal RRSP.
- Uneven balances beyond 50%. Splitting caps at half; a spousal RRSP can put 100% of a contribution into the low earner’s hands.
- Age-71 planning. If the contributor is over 71 but the annuitant is younger, the contributor can keep contributing to the spousal plan (with their own room) until the end of the year the annuitant turns 71.
Common mistakes
- Withdrawing within the window. The most frequent error. Track the last contribution date and wait for the third January 1.
- Contributing from the annuitant’s own funds. Only the contributor may claim the deduction; the source of money does not matter, the deduction does.
- Confusing the plans. Contributions to the annuitant’s own RRSP are not spousal and do not trigger attribution; only plans flagged as spousal do.
- Forgetting the HBP. A spousal RRSP can be used for a Home Buyers’ Plan withdrawal, which is not subject to attribution, but the 90-day rule applies.
Key takeaways
- Contributor’s room, contributor’s deduction, annuitant’s plan and annuitant’s tax on withdrawal.
- Withdrawals within the contribution year or the next two calendar years are taxed back to the contributor.
- Contribute early in the year to shorten the wait.
- Most valuable for pre-65 withdrawals and for shifting more than half of retirement income.
