Spousal RRSP: How Income Splitting Works for Retirement
If you and your partner have a significant income gap, a Spousal RRSP is one of the most effective tools for reducing your household’s total tax bill in retirement. Here’s how it works.
What Is a Spousal RRSP?
A Spousal RRSP is an RRSP account owned by your spouse or common-law partner, but funded with your contributions. You get the tax deduction, but the money belongs to your spouse. When they withdraw in retirement, it’s taxed at their (presumably lower) rate.
How It Reduces Tax
Canada’s tax system is progressive. Equal incomes between two people produce less total tax than the same combined income concentrated in one person. By putting RRSP money in the lower-earner’s name, you equalize retirement income and reduce the household’s total tax.
Example
Without spousal RRSP: Partner A withdraws $80,000/year from RRSP. Partner B withdraws $20,000. Partner A pays significantly more tax due to higher marginal rates.
With spousal RRSP: Each partner withdraws ~$50,000. Total household tax is lower because both are in more moderate brackets.
Key Rules
Contribution room
Spousal RRSP contributions use the contributor’s (higher earner’s) RRSP deduction room. They do not create or use the spouse’s room.
The 3-year attribution rule
If the spouse withdraws from the spousal RRSP within 3 calendar years of the last contribution, the withdrawal is attributed back to the contributor and taxed at their rate. The clock resets with each new contribution.
This rule means spousal RRSP works best as a long-term strategy. Don’t contribute and withdraw in the same year or shortly after.
Age limit
You can contribute to a spousal RRSP until your spouse turns 71, even if you’re past 71 yourself (as long as you have contribution room).
Spousal RRSP vs Pension Splitting
After age 65, pension splitting allows you to allocate up to 50% of eligible pension income to your spouse without needing a spousal RRSP. RRIF withdrawals qualify after 65.
So when does spousal RRSP still matter?
- Before age 65 (pension splitting isn’t available yet)
- When you want to equalize capital between spouses for estate planning
- When one spouse has little or no RRSP savings of their own
5 Tips
- Start early. The 3-year attribution rule means early contributions have more flexibility.
- Stop contributing 3+ years before your spouse plans to withdraw.
- Don’t overlook CPP sharing. Combine with spousal RRSP for maximum income equalization.
- Consider OAS clawback. Equalizing income can keep both partners under the OAS clawback threshold.
- Track contribution room carefully. Spousal contributions reduce your room, not your spouse’s.
