What Is the Spousal RRSP Attribution Rule?
A spousal RRSP moves retirement income to a lower-taxed spouse, but only if the money stays put. Withdraw within the window after a contribution and the amount is taxed back to the contributor instead, which defeats the entire purpose of the arrangement.
- The answer:: If you contributed to a spousal RRSP in the year of a withdrawal or either of the two preceding calendar years, the withdrawal is attributed back to you.
- The trap:: Counting three years from the contribution date. The rule counts calendar years, so a December contribution can be caught by a withdrawal barely two years later.
- The recommendation:: Contribute in early January rather than late December where a withdrawal may be needed, because it moves the window a full year in your favour.
Where the AI summary above gets this wrong
"Contribute to a spousal RRSP and your spouse pays the tax when they withdraw."
That's surface-true. Here's what it misses:
- Only after the window — A withdrawal made within the attribution period is taxed to the contributor, so the transfer of tax does not happen at all.
- Calendar years, not anniversaries — The count is by calendar year, which means a December contribution and a January withdrawal two years later can still be caught.
- Converting changes the rules — Once converted to a spousal RRIF, minimum withdrawals are generally not subject to attribution, though amounts above the minimum can be.
01 What the rule does
A spousal RRSP is contributed to by one spouse and owned by the other, so that retirement withdrawals are taxed in the lower-income spouse's hands. The attribution rule stops that being used for short-term income shifting.
If you contributed to any spousal RRSP in the year of a withdrawal or in either of the two preceding calendar years, the withdrawal — up to the total of those contributions — is included in your income instead of your spouse's.

02 Why the calendar matters
The window is counted in calendar years, not from the contribution date. A contribution made in December 2026 is caught by withdrawals in 2026, 2027 and 2028, so a withdrawal in January 2029 is clear — barely two years and one month later.
Contributing in early January instead pushes the whole window forward by a year for one month of delay. Where a withdrawal might be needed, that is the single most valuable timing decision in the arrangement.
Shows: what a given amount of additional taxable income costs you in tax at your marginal rate, and what you keep. Ignores: provincial surtaxes, credits that phase out with income, and any effect on income-tested benefits.

03 After conversion
Once a spousal RRSP becomes a spousal RRIF, the prescribed minimum withdrawal is generally not attributed back to the contributor. Amounts taken above the minimum can still be caught by the same rule.
That distinction makes the conversion a natural point to stop contributing, and it interacts with how the RRIF minimum is calculated, since the minimum is the amount that escapes attribution.
Keeping spousal and personal plans in separate accounts is the administrative habit that makes all of this workable. Where contributions of both kinds sit in one plan, a withdrawal draws on both and the attribution calculation has to untangle them afterwards; two accounts make the question of which money is being withdrawn answerable straight from the statement.

The calendar-year detail is the one that catches people, because it sounds like a three-year rule and behaves like one that can be as short as two years and a month. Anyone contributing to a spousal plan in December for the deduction should know they have just extended the lock-in by a full year compared with waiting three weeks.
FAQ
Who pays tax on a spousal RRSP withdrawal?
Normally the annuitant spouse. But if the contributor made a spousal contribution in the year of the withdrawal or either of the two preceding calendar years, the withdrawal is attributed back and taxed to the contributor.
Is the window three years from the contribution date?
No, it is counted in calendar years. A December contribution is caught by withdrawals in that year and the next two, so contributing in early January instead shifts the window forward by a full year.
Does attribution apply to a spousal RRIF?
The prescribed minimum withdrawal is generally not attributed back to the contributor. Amounts withdrawn above the minimum can still be caught by the same rule.
