Spousal RRSP Calculator — Reduce Your Family Tax Bill
Calculate tax savings from Spousal RRSP contributions. See how income splitting in retirement reduces your combined family tax burden.
A Spousal RRSP allows the higher-income spouse to contribute to the lower-income spouse RRSP using the contributor own contribution room. The contributor gets the tax deduction at their higher marginal rate while the spouse eventually withdraws at their lower rate in retirement. This income-splitting strategy can save Canadian couples thousands in taxes annually during retirement by equalizing both spouse incomes.

How much tax can Spousal RRSP save?
If one spouse earns $120000 (43.5% marginal rate) and the other earns $30000 (20.5%): contributing $20000 to Spousal RRSP saves $8700 in tax now. In retirement the spouse withdraws at 20.5% paying $4100 tax. Net family saving: $4600 per year. Over 20 years of retirement this saves $92000 in total family taxes — a massive benefit for unequal-income couples.
What is the 3-year attribution rule?
If the spouse withdraws Spousal RRSP contributions within 3 calendar years the withdrawal is attributed back to the contributor and taxed at their higher rate. This prevents short-term income splitting. Contributions made more than 3 calendar years ago are taxed in the spouse hands at their lower rate. Plan contributions well in advance of any anticipated withdrawals.
Can both spouses have RRSPs and Spousal RRSPs?
Yes. Each spouse can have their own RRSP plus a Spousal RRSP. The higher earner contribution room is shared between their own RRSP and the Spousal RRSP. For example if the higher earner has $27830 contribution room they could put $15000 in their own RRSP and $12830 in the Spousal RRSP. The lower earner own RRSP uses their own separate contribution room.
