Spousal RRSP Tax Deduction: Limits, Claiming, and Attribution Rules

The spousal RRSP tax deduction is claimed by the contributing spouse, not the plan’s owner: you put money into an RRSP registered in your partner’s name, and you deduct the contribution on your own return against your own deduction room. For the 2026 tax year, that room is 18% of your 2025 earned income up to a ceiling of $33,810, plus any unused room carried forward from prior years.¹ The deduction goes on Line 20800 of your T1, and the long-term point is that withdrawals in retirement are taxed in your lower-earning spouse’s hands.

Who Can Claim the Deduction

You qualify as a contributor if you have a legally married spouse or a common-law partner you have lived with continuously for at least 12 months. A marriage certificate or proof of a shared address is enough to establish the relationship if the CRA asks.

The annuitant — the spouse who owns the plan — must be no older than 71 on December 31 of the contribution year. Once they reach that age, the plan has to be converted to a RRIF, used to buy an annuity, or collapsed, and no further contributions are allowed.² Your own age doesn’t restrict you: if you’re under 71 but your spouse is past it, you can still contribute to your own RRSP, just not to theirs.

Contributions made in the first 60 days of the following calendar year still count for the current tax year. For 2026, that means any spousal RRSP contribution made on or before March 1, 2027 is deductible on your 2026 return.³

How Much You Can Deduct for 2026

Every dollar you send to a spousal RRSP comes out of your own deduction room, not your spouse’s. The CRA calculates that room as 18% of your prior-year earned income, capped at the annual dollar limit: $32,490 for 2025 and $33,810 for 2026.⁴¹ Unused room from prior years stacks on top. Your exact figure appears on your most recent Notice of Assessment.

Your own RRSP and any spousal RRSPs share a single pool. If you have $25,000 of room and put $15,000 in your own plan, you have $10,000 left for the spousal plan. Split it however you like; the total is what matters.

The $2,000 Over-Contribution Buffer

The CRA permits a lifetime over-contribution of up to $2,000 above your deduction limit without penalty. You get no deduction for that extra $2,000, but you also don’t owe the monthly surcharge.⁵ Cross the buffer and the penalty is 1% per month on the excess until you withdraw it or grow into it with new room.⁴ The buffer covers your combined personal and spousal contributions. It doesn’t double because two accounts are involved.

How to Claim It on Your Tax Return

Your financial institution issues a contribution receipt for each deposit, naming your spouse as the annuitant and showing the amount and date. Keep the receipts. They’re your primary proof if the CRA follows up.

Report all RRSP contributions on Schedule 7, “RRSP, PRPP and SPP Contributions and Transfers and HBP and LLP Activities.” The form has separate sections for contributions to your own plan and contributions to your spouse’s plan, so complete both if you contributed to both.⁶ The deduction total from Schedule 7 carries to Line 20800 of your T1 General and reduces your taxable income.

NETFILE-certified software moves the number from Schedule 7 to Line 20800 for you.⁷ On paper, attach Schedule 7 to your return and mail it to your CRA tax centre. Either route, your next Notice of Assessment shows the deduction applied and your updated room for the following year.

Deferring the Deduction to a Higher-Bracket Year

The contribution and the deduction don’t have to happen in the same year. If you expect a higher tax bracket next year, contribute now, report the contribution on this year’s Schedule 7, and leave it off Line 20800. The CRA tracks the unused amount and you claim it on a future return when it saves more tax.⁶ The contribution still uses room in the year you make it; deferring the deduction doesn’t create extra room.

The Three-Year Attribution Rule

The rule that most often undoes the tax benefit works like this. If your spouse withdraws from a spousal RRSP, and you contributed to any of their spousal RRSPs in the current calendar year or either of the two preceding calendar years, the withdrawn amount is added to your income instead of theirs, up to the total of those recent contributions.⁸ You then pay at your higher marginal rate, which cancels the split.

Timing is strictly calendar-year based. A contribution made in January 2024 keeps the attribution window open through December 31, 2026. A withdrawal in January 2027 is taxed entirely in your spouse’s hands.⁹ Attribution also looks across plans: if your spouse has two spousal RRSPs and you contributed to one, a withdrawal from the other still triggers the rule. The CRA totals recent spousal contributions across every spousal plan.

When Attribution Doesn’t Apply

The Income Tax Act sets out situations where the three-year rule is switched off even when recent contributions exist:

You and your spouse are living separate and apart because of a breakdown in your marriage or common-law partnership at the time of the withdrawal.¹⁰
The contributing spouse died in the year of the withdrawal.
Either spouse is a non-resident of Canada at the time of the withdrawal.¹⁰
The plan has been converted to a RRIF and your spouse takes only the required minimum annual payment. Anything above the minimum is still subject to attribution if recent contributions were made.

Home Buyers’ Plan and Lifelong Learning Plan Withdrawals

HBP and LLP withdrawals are not treated as ordinary withdrawals for the attribution rule, but there is a separate timing trap that can strip you of a deduction.

Your spouse can withdraw up to $60,000 from a spousal RRSP under the Home Buyers’ Plan to buy or build a qualifying first home.¹¹ If you contributed to that plan within 89 days before the withdrawal and its value after the withdrawal falls below the amount of those recent contributions, part of the contribution becomes non-deductible based on the shortfall.¹² Stop contributing at least 90 days before your spouse makes an HBP withdrawal to protect the deduction.

Under the Lifelong Learning Plan, your spouse can withdraw up to $10,000 per year, and $20,000 in total, from their RRSP to fund qualifying full-time education or training, for themselves or for you. LLP amounts aren’t included in income at withdrawal, and no tax is withheld; the amounts must be repaid over 10 years, and any missed repayment is added to your spouse’s income for that year.¹³

A Note on Death and Separation

Two situations affect who can still claim the deduction. If the contributing spouse dies, no more contributions can go to their own RRSP, but the legal representative can contribute to the surviving spouse’s RRSP in the year of death or the first 60 days after, and claim the deduction on the deceased’s final return up to their remaining room.⁹ On relationship breakdown, funds can be transferred tax-free to the former spouse’s individual RRSP using CRA Form T2220, and, because attribution no longer applies once you are living apart due to the breakdown, the annuitant can withdraw and be taxed at their own rate.¹⁴
