Spousal RRSP Decision Calculator
Should you contribute to a spousal RRSP, or use a regular RRSP and rely on T1032 pension splitting in retirement? This tool runs both strategies and flags the 3-year attribution trap that wipes out the spousal RRSP benefit if you withdraw too soon.
Your scenario
Recommended strategy
Spousal RRSP
Saves $530 in withdrawal-year tax vs the other strategy.
Strategy A — Spousal RRSP
You contribute; spouse is the annuitant and withdraws.
Strategy B — Regular RRSP + T1032 split
You contribute and withdraw; split up to 50% with spouse if 65+.
How the 3-year attribution rule works
Under ITA s.146(8.3), a withdrawal from a spousal RRSP is attributed back to the contributor's income if the contributor made any spousal contribution in:
- The year of withdrawal, OR
- Either of the two preceding calendar years
Effectively, a contribution is "locked" for three calendar years. A 2026 contribution is only fully safe from attribution from 1 January 2029 onward. Planning tip: stop spousal contributions at least 3 years before the spouse plans to withdraw, or route withdrawals through a spousal RRIF at minimum mandatory amounts only.
When spousal RRSP beats regular + T1032
| Scenario | Winner |
|---|---|
| Higher earner retires at 55, spouse has no pension | Spousal RRSP (T1032 unavailable under 65) |
| Both spouses retire at 65 with similar pensions | Roughly tied — either works |
| Higher earner has large DB pension, spouse has none | Spousal RRSP (50% T1032 split leaves contributor in top bracket) |
| Withdrawal planned within 3 years of contribution | Regular RRSP — spousal loses to attribution |
| Spouse has HIGHER retirement income than contributor | Regular RRSP + T1032 (reverse split) |
Frequently asked questions
What is the 3-year attribution rule?
If any spousal contribution was made in the current or previous 2 calendar years, a withdrawal from the spousal RRSP is taxed in the contributor's hands instead of the annuitant's. ITA s.146(8.3). A 2026 contribution is safe from attribution starting 2029.
Can I use T1032 pension splitting instead?
T1032 is available from age 65 and caps at 50% of eligible pension income. A spousal RRSP lets the lower-earning spouse withdraw 100% at their own rate, which is a bigger shift. T1032 is a better choice when retirement incomes are already similar.
Does RRIF conversion avoid attribution?
RRIF mandatory minimum withdrawals are not attributed to the contributor — only the portion above the minimum is. Converting a spousal RRSP to a spousal RRIF at age 65+ and drawing only the minimum is the standard workaround.
Do HBP/LLP withdrawals trigger attribution?
No. HBP and LLP withdrawals are specifically excluded from the attribution rule. If the HBP isn't repaid on time, the missed payment is included in the annuitant's income.
Whose RRSP contribution room is used?
The contributor's room — even though the account is in the spouse's name. The contributor claims the deduction at their marginal rate. The spouse's own RRSP room is untouched.
