Spousal RRSPs: Income Splitting Explained

A spousal RRSP is an RRSP in one spouse's name that the other spouse contributes to. The point is income splitting in retirement: the higher earner gets the deduction now, at their high rate, and the lower earner withdraws the money later, at their low rate. It works — but only if you respect the 3-year attribution rule. Withdraw too soon and the income is taxed back to the contributor.

How a spousal RRSP works

The annuitant is the spouse who owns the account. The contributor is the spouse who puts the money in. The contribution uses the contributor's RRSP room and gives the contributor the deduction — the annuitant's room is untouched. When the money comes out in retirement, it is normally taxed to the annuitant, who is usually in a lower bracket. That is the whole benefit: a deduction at a high rate, a withdrawal at a low rate.

The 3-year attribution rule

The attribution rule stops people from using a spousal RRSP as a short-term tax dodge. If the annuitant withdraws money and the contributor made a contribution to any spousal RRSP in the year of the withdrawal, or in either of the two preceding calendar years, the withdrawal is taxed to the contributor — up to the amount of those contributions. So a contribution made in 2024 can taint a withdrawal made in 2024, 2025, or 2026. The rule counts calendar years, not 36 months: a contribution on 31 December 2024 and a withdrawal on 1 January 2027 are in different three-year windows, even though only two years and a day have passed.

Exceptions

Attribution does not apply if the contributor has died, if either spouse was a non-resident at the time, or if the spouses are separated because the relationship has broken down. It also does not apply to the minimum withdrawals from a spousal RRIF — those are always taxed to the annuitant. The form for reporting an attributed withdrawal is T2205.

Why couples use them

The classic use is a couple where one spouse earns much more than the other. The higher earner contributes to the lower earner's spousal RRSP for years, the money grows, and in retirement the lower earner withdraws it at a low rate — splitting income that would otherwise all be taxed to the higher earner. Pension income splitting on the tax return does some of the same work, but a spousal RRSP lets a couple split income before age 65, when pension splitting is more limited. The key discipline is timing: stop contributing at least three calendar years before the withdrawals begin.
