Spousal RRSP and XEQT: The Income-Splitting Strategy Most Canadian Couples Miss

My partner and I have a pretty typical Canadian household income split: I earn about $110,000 per year, and she earns about $55,000 working part-time while raising our kids. For years, I was maxing out my own RRSP, feeling pretty good about the tax deduction, and not thinking much beyond that.

Then a friend who’s an accountant casually mentioned spousal RRSPs over dinner. “You’re leaving thousands on the table,” she said. I didn’t believe her at first. But after running the numbers, I realized she was right – and I was kicking myself for not starting sooner.

If you and your partner have different incomes, a spousal RRSP filled with XEQT might be the single most valuable tax strategy you’re not using. Let me explain why.

1. What Is a Spousal RRSP?

A spousal RRSP is a registered retirement savings plan that belongs to your spouse (or common-law partner), but where you make the contributions and get the tax deduction.

Here’s the key distinction:

• Regular RRSP: You contribute to your own RRSP. You get the deduction. When you withdraw in retirement, it’s taxed as your income.
• Spousal RRSP: You contribute to your spouse’s RRSP. You get the deduction. When your spouse withdraws in retirement, it’s taxed as their income.

Why does this matter? Because Canada has a progressive tax system. The more income you earn, the higher your marginal tax rate. If one spouse has a much higher income (and thus a higher tax rate), having both spouses withdraw similar amounts in retirement keeps more total money in the lower tax brackets.

This is income splitting, and it’s one of the most effective legal tax strategies available to Canadian couples.

2. How the Tax Savings Actually Work

Let’s make this concrete with numbers. These use approximate 2026 federal + Ontario combined marginal tax rates:

Scenario: No Spousal RRSP (All RRSP Savings in Higher Earner’s Name)

Scenario: With Spousal RRSP (Savings Split More Evenly)

Annual tax savings: approximately $1,500

Over a 25-year retirement, that’s $37,500 in tax savings – just from splitting where the money sits. And the savings can be even larger for couples with bigger income gaps or larger RRSP balances.

3. The Contribution Rules (It’s Simpler Than You Think)

Here are the most important rules for spousal RRSP contributions:

Who Has the Contribution Room?

The contributing spouse (the higher earner) uses their own RRSP contribution room. Contributing to a spousal RRSP does NOT create extra room. It comes from the same annual limit.

Example: If your RRSP deduction limit is $25,000, you can put:

• $25,000 into your own RRSP, or
• $25,000 into a spousal RRSP, or
• $15,000 into yours and $10,000 into the spousal RRSP, or
• Any other split that totals $25,000

Who Owns the Account?

The annuitant spouse (the lower earner) owns the account. It’s their money. They control it. They decide how it’s invested. And in retirement, they’re the ones who withdraw from it and pay tax on the withdrawals.

The Tax Deduction

The contributor claims the tax deduction, regardless of who owns the account. If you contribute $10,000 to your spouse’s spousal RRSP, that $10,000 comes off your taxable income.

Age Limits

The contributor can keep contributing until December 31 of the year the annuitant (account-holder spouse) turns 71. This can extend the contribution window if the lower-earning spouse is younger.

4. The 3-Year Attribution Rule: The One Rule You Must Follow

This is the most important rule to understand, and the one most people get wrong.

If the annuitant spouse withdraws from the spousal RRSP within 3 calendar years of the last contribution, the withdrawal is “attributed back” to the contributing spouse and taxed as the contributor’s income.

Let’s break that down:

• You contribute to the spousal RRSP in January 2026
• The 3-year window covers 2026, 2027, and 2028
• If your spouse withdraws any amount before January 1, 2029, that withdrawal (up to the amount of contributions made in the last 3 years) is taxed in your hands, not theirs

This completely defeats the purpose of income splitting.

How to Avoid the Attribution Trap

The rule is based on calendar years, not a rolling 36-month window. So:

• A contribution made on December 31, 2026 – must wait until January 1, 2029 to withdraw (only 2 years and 1 day!)
• A contribution made on January 1, 2026 – must also wait until January 1, 2029 (a full 3 years)

Strategic tip: If you know your spouse might need to withdraw within a few years, make contributions in December to minimize the effective waiting period.

For long-term XEQT investors aiming for retirement, this rule is rarely a problem. You’re not planning to withdraw for years or decades. But it’s critical to know in case life throws you a curveball.

5. Why XEQT Is the Perfect Spousal RRSP Investment

You could put anything in a spousal RRSP – GICs, mutual funds, individual stocks. But XEQT is uniquely well-suited for this account:

Set It and Forget It

A spousal RRSP is often a “secondary” account that doesn’t get as much attention as your primary RRSP or TFSA. XEQT requires zero maintenance. No rebalancing, no stock picking, no monitoring. You contribute, buy XEQT, and let it compound for decades.

Automatic Rebalancing

BlackRock rebalances XEQT across its four underlying funds automatically. Over 20-30 years, this ensures the portfolio stays properly diversified without any action from you or your spouse.

Low Fees for Maximum Compounding

At 0.20% MER, XEQT’s fees are a fraction of what most mutual funds charge. In a spousal RRSP where the money might compound for 25+ years before withdrawal, low fees make an enormous difference:

That $122,000 difference is money that stays in the spousal RRSP, compounding and growing, eventually providing more retirement income at a lower tax rate. It’s a double win.

Global Diversification in an RRSP

There’s actually a tax-specific reason XEQT works well inside an RRSP. Foreign withholding taxes on US dividends are recoverable inside an RRSP (thanks to the Canada-US tax treaty), but not inside a TFSA. Since about 45% of XEQT is US stocks, holding it in an RRSP (including a spousal RRSP) can be slightly more tax-efficient.

6. Who Should Use a Spousal RRSP?

Spousal RRSPs make the most sense for couples with a significant and lasting income difference. Here are the scenarios where they shine:

Great Candidates

• One spouse earns $100,000+ and the other earns under $50,000 – Maximum tax bracket arbitrage
• One spouse is a stay-at-home parent – Building their retirement savings with the working spouse’s contribution room
• Self-employed + employed couples – Self-employed spouse often has variable income; spousal RRSP provides stability
• Couples planning for one spouse to retire early – The early retiree can start withdrawing from the spousal RRSP at lower tax rates

Less Ideal Situations

• Both spouses earn similar incomes – Less benefit to splitting since they’re already in similar tax brackets
• Both spouses have maxed their own RRSP room – You can’t contribute more than your own room allows
• Very young couples with no kids yet – Income disparity might change; focus on TFSAs first

A Note on Pension Income Splitting at 65

After age 65, Canadian tax rules allow you to split up to 50% of “eligible pension income” with your spouse. RRSP/RRIF withdrawals count as eligible pension income after 65. This means that for many couples, pension splitting at 65 can accomplish some of the same income-evening that a spousal RRSP does.

However, a spousal RRSP still helps in several ways:

• Before age 65: No pension splitting is available. If one spouse retires early (say at 55), a spousal RRSP is the only way to split income.
• Beyond the 50% limit: Pension splitting maxes out at 50%. A spousal RRSP with its own balance can push the split further.
• Flexibility: Having two separate RRSP/RRIF accounts gives you more withdrawal strategy options.

7. How to Set Up a Spousal RRSP on Wealthsimple

Setting up a spousal RRSP on Wealthsimple is straightforward:

1. Both spouses need Wealthsimple accounts – If your spouse doesn’t have one yet, sign up using the link below.

2. The annuitant spouse (lower earner) opens the spousal RRSP – In the Wealthsimple app, go to Accounts and select “Add account.” Choose RRSP, then select “Spousal RRSP.”

3. Link the contributor – The system will ask for the contributing spouse’s information to link the accounts properly.

4. Fund the account – The contributing spouse transfers money into the spousal RRSP. This uses the contributor’s RRSP room.

5. Buy XEQT – Once funds settle, purchase XEQT in the spousal RRSP.

6. Set up recurring contributions – Automate monthly or bi-weekly contributions to make the strategy hands-off.

The whole process takes about 15 minutes. And because Wealthsimple has no commissions and no account fees, there’s zero cost to maintaining the extra account.

8. Spousal RRSP Strategy: How to Decide the Split

The big question: how much should go into your own RRSP vs. the spousal RRSP?

The Simple Rule of Thumb

Aim for roughly equal RRSP balances at retirement. If you expect to retire with $500,000 in total RRSP savings, try to have about $250,000 in each spouse’s name.

The More Precise Approach

Consider each spouse’s expected retirement income from all sources:

• CPP (will be different based on each person’s contribution history)
• OAS (same for both if both are Canadian residents for 40+ years)
• Workplace pensions (if any)
• RRSP/RRIF withdrawals
• Other income

Add up each spouse’s expected retirement income. If one spouse’s total is significantly higher, route more RRSP contributions to the lower-income spouse via the spousal RRSP.

My Approach

Since I earn roughly double what my partner earns, and she’ll have lower CPP benefits from working part-time, I split my RRSP contributions roughly 60/40 in favor of the spousal RRSP. This should result in roughly similar retirement income for both of us, keeping us both in the same (lower) tax bracket.

9. Common Mistakes with Spousal RRSPs

Mistake 1: Confusing Contribution Room

Remember: contributions to a spousal RRSP use the contributor’s room, not the annuitant’s. If you have $20,000 in RRSP room and your spouse has $8,000, you can put up to $20,000 into the spousal RRSP. Your spouse’s $8,000 room is for their own personal RRSP.

Mistake 2: Withdrawing Within 3 Years

As discussed above, this triggers attribution and defeats the purpose. Plan for at least a 3-year holding period after the last contribution.

Mistake 3: Not Coordinating with TFSA Strategy

A spousal RRSP should be part of your overall tax strategy, not a standalone decision. For many couples, the priority order is:

1. Max the higher earner’s employer RRSP match (if available)
2. Max both TFSAs ($7,000 each in 2026)
3. Contribute to the spousal RRSP with remaining RRSP room
4. Consider FHSAs if applicable
5. Non-registered accounts for anything left over

Mistake 4: Forgetting to Update Your Tax Return

When you contribute to a spousal RRSP, you claim the deduction, not your spouse. Make sure you’re entering the contribution on the correct person’s tax return. Your RRSP receipt will show it as a spousal contribution.

Mistake 5: Not Considering the Marriage Breakdown Scenario

I don’t like thinking about this either, but it’s practical: in a divorce, spousal RRSP assets are generally considered the annuitant spouse’s property (though marital assets are typically split). Consult a family lawyer or financial planner if this is a concern.

10. When a Spousal RRSP Might NOT Be the Best Choice

Spousal RRSPs aren’t for everyone. Consider alternatives in these situations:

• Both spouses have similar high incomes: Standard RRSP contributions with future pension splitting at 65 may be sufficient.
• Both spouses have workplace pensions: These pensions may already equalize retirement income.
• Short time horizon: If you’re close to retirement and both spouses will be 65+ soon, pension splitting may accomplish the same goal more simply.
• TFSA room available: If either spouse still has TFSA room, those contributions provide tax-free growth with no withdrawal restrictions. Max TFSAs first.

The Bottom Line

A spousal RRSP is one of those strategies that sounds complicated but is actually quite simple in practice. The higher-earning spouse contributes, gets the tax deduction today, and the lower-earning spouse withdraws at a lower tax rate in retirement. Fill it with XEQT and you have a low-cost, globally diversified, self-managing retirement account that could save your family tens of thousands of dollars in taxes over your lifetime.

My only regret is not starting sooner. Every year I contributed everything to my own RRSP instead of splitting with a spousal RRSP was a year of lost income-splitting potential.

If you and your partner have different incomes – even if the gap isn’t enormous – it’s worth running the numbers. The setup takes 15 minutes. The potential tax savings over a 25-year retirement can be life-changing.
