Spousal RRSP: still useful after income splitting

When pension income splitting arrived, the common view was that spousal RRSPs had been made redundant. That is right for a large part of the problem and wrong for the parts that matter most to early retirees.

The mechanic

The room is shared with personal contributions rather than added to them. A spouse with a given deduction limit can split it between their own RRSP and a spousal RRSP in any proportion — but the total is still their limit.

The four gaps pension splitting leaves

  1. Splitting RRIF income requires the transferor to be 65. A couple retiring in their fifties has a decade of drawdown before it becomes available at all.
  2. The election covers at most half of eligible income. A very lopsided couple can still leave one spouse in a materially higher bracket after splitting everything they are allowed to.
  3. Withdrawals from an RRSP that has not been converted to a RRIF are not eligible income. A spousal RRSP works regardless of account type, because the money is genuinely the other spouse’s.
  4. Splitting needs two living spouses. Balances that were built in the right name stay in the right name; an election does not survive a death.

The first is the big one. Anyone planning to stop work before 65 is choosing between drawing down one spouse’s large registered balance at their full marginal rate, or having built a balance in the other spouse’s name years earlier.

The attribution rule

There is a guardrail, and it is worth knowing before contributing. If the annuitant spouse withdraws from a spousal RRSP within a defined window of the last contribution, the withdrawal is taxed back to the contributor rather than the annuitant. The rule exists to stop a contribution being made and immediately withdrawn at a lower rate.

In practice it means spousal contributions and spousal withdrawals want to be separated by time. A couple contributing through their working years and withdrawing after retirement is nowhere near the rule; a couple contributing in December and withdrawing in January is squarely inside it.

Where the imbalance came from

Dan & Marie — 58 and 56, Alberta. Dan retires at 62 with a defined-benefit pension; Marie retires at 60. Their RRSPs are very different sizes, which matters later.

Dan earns $132,000 and holds $540,000; Marie earns $74,000 and holds $165,000. Neither number is unusual — the higher earner had more room and contributed more, year after year, and the gap compounded.

Dan holds $540,000 in registered savings against Marie's $165,000, an imbalance built by decades of contributing from a $132,000 salary against a $74,000 one.
The imbalance is a by-product of the contribution years, not a decision anyone made.

Dan’s balance is what drives their large mandatory withdrawals after 71, and those withdrawals are concentrated on his return. Some of that can be split once he is 65; the years before that, and the half that cannot be transferred, cannot.

How it is modelled

A spousal RRSP is economically the annuitant’s RRSP: it grows with their account, converts on their timetable, produces their mandatory withdrawals and passes through their estate. The only thing that differs is where the contribution came from and whose room it consumed — which is exactly how a projection should treat it.

The accounts section supports a spousal RRSP in either direction, debiting the contributor’s room and crediting the annuitant’s balance, so the effect on both people’s retirement income is projected rather than assumed.
