If you and your partner earn very different incomes, the spousal RRSP is one of Canada's most effective, and underused, tax strategies. It's especially relevant for couples where one person took time off work, works part-time, or earns significantly less.
What Is a Spousal RRSP?
A spousal RRSP is an RRSP that you contribute to on behalf of your spouse or common-law partner. The account is registered in your spouse's name, but you use your own contribution room and get the tax deduction.
In retirement, your spouse withdraws the money and pays tax on it at their (lower) rate, not yours.
Why Does This Matter?
Canada taxes individuals, not households. If one partner has $80,000 in retirement income and the other has $20,000, the higher earner pays a much higher rate. If you could split that to $50,000/$50,000, you'd pay less total tax.
The spousal RRSP is one tool to achieve that balance, by building up the lower-income spouse's retirement savings now.
How It Works in Practice
You contribute to your spouse's RRSP using your own contribution room. The deduction is yours. The account grows in their name. When they withdraw in retirement, it's their income.
Important rule: if your spouse withdraws within three years of your contribution, the withdrawal is taxed as your income (not theirs). CRA calls this the attribution rule. So the spousal RRSP strategy works best when retirement is more than three years away.
Who Benefits Most
- Couples where one earns much more than the other
- Families where one partner paused their career for caregiving (common among newcomer families)
- Self-employed individuals with variable income
- Couples where one partner is significantly younger and will have a longer retirement
An Ottawa Example
Imagine a couple in Ottawa where one partner works as a software developer at Shopify's Ottawa office earning $130,000, and the other is a part-time ESL teacher earning $28,000. The developer contributes $10,000/year to the spouse's RRSP for 20 years. In retirement, the teacher withdraws that income at a much lower tax rate, saving the household thousands annually.
Setting One Up
Any major bank or brokerage can open a spousal RRSP. You'll need both partners' SINs. Contributions and deductions are tracked separately from your own RRSP.
If you're unsure whether a spousal RRSP fits your situation, a fee-only financial planner, many practise in Ottawa, can model out the long-term tax savings for your specific household.
