High Earner Spouse? Stop Contributing to Your Own RRSP. Why 'Spousal RRSP' is the Ultimate Income Splitting Hack

High Earner Spouse? Stop Contributing to Your Own RRSP.

Canada has a "progressive" tax system. This means if you earn $250,000, you pay a punishingly higher percentage of tax (over 53% in some provinces) compared to your spouse who earns $50,000 (approx. 20-25%).

As a family, this is painful. You look at your combined household income and wish you could just "average it out" to lower your total tax bill. Generally, the CRA does not allow this.

However, there is one powerful exception designed specifically for couples: The Spousal RRSP.

It is legally sanctioned "Income Splitting." It allows the higher-earning spouse to transfer future tax burdens to the lower-earning spouse, potentially saving the family tens of thousands of dollars.

How It Works: The "Tax Arbitrage"

A Spousal RRSP is an account registered in your spouse's name (the Annuitant), but you (the Contributor) put the money in.

• The Contribution (Today): You (the high earner) contribute money. You get the tax deduction immediately at your high marginal tax rate (e.g., 53%).
• The Withdrawal (Future): Years later, your spouse (the low earner) withdraws the money. They pay the income tax at their low marginal tax rate (e.g., 20%).

💰 The Math: Saving $16,500 instantly

Let's say Husband earns $250k (53% tax rate) and Wife earns $40k (20% tax rate).

Husband contributes $50,000 to a Spousal RRSP for his wife.

1. Today: Husband gets a $26,500 tax refund ($50k x 53%).
2. Future: Wife withdraws the $50,000 in retirement. She pays only $10,000 in tax ($50k x 20%).

Net Profit: The family saved $16,500 purely by shifting who pays the tax. If the husband had used his own RRSP, he would have paid the high tax rate upon withdrawal.

Whose Room Is Used? (Don't Mess This Up)

This is a common point of confusion.

Contributions to a Spousal RRSP use up the CONTRIBUTOR'S (High Earner's) room.

• 2026 RRSP Limit: The maximum is $33,810.
• If the husband puts $33,810 into the wife's Spousal RRSP, his personal RRSP limit drops to $0 for the year.
• The wife's RRSP room remains untouched (she can still contribute to her own plan if she wants).

The Trap: The "3-Year Attribution Rule"

The CRA isn't stupid. They know you want to do this to save tax immediately. So, they created a strict rule to prevent "churning."

The Rule: If the spouse withdraws money from the Spousal RRSP in the year of contribution OR the two preceding calendar years, the income "bounces back" (attributes) to the Contributor.

📅 The Safe Timeline Example

• Dec 2026: You contribute $10,000.
• 2027 & 2028: You contribute $0 to any Spousal RRSP. (You must wait 2 full calendar years).
• Jan 1, 2029: Your spouse withdraws the money.

Result: Since no contributions were made in 2029, 2028, or 2027, the income is taxed in the spouse's hands. You win.

The Exception: The "HBP" Loophole

Here is a massive secret for young couples buying a home in 2026.

If you use the Home Buyers' Plan (HBP) to withdraw funds (up to $60,000) for a down payment, the Attribution Rule does NOT apply.

You can contribute $60,000 to your spouse's Spousal RRSP today, get the massive tax refund, and she can withdraw it for a house purchase 90 days later tax-free (as a loan). The 3-year wait is waived!

Why Do This? (Beyond Age 65)

You might ask: "But the government allows Pension Splitting after age 65. Why bother?"

Pension splitting (RRIF splitting) indeed kicks in at age 65. But Spousal RRSPs are superior for:

1. Early Retirees (FIRE): If you retire at 55, you cannot split regular RRSP income yet. But you CAN withdraw from a Spousal RRSP at 55 and split the income immediately (assuming the 3-year rule is met).
2. The Age Gap Strategy: If you are 71 (must close your RRSP) but your spouse is only 55, you can keep contributing to a Spousal RRSP until she turns 71. This lets you generate tax deductions for an extra 16 years!

Balance the Scales

In Canada, the ideal retirement scenario is for both spouses to have equal nest eggs, so they both stay in the lowest possible tax brackets.

If one of you has a giant RRSP and the other has nothing, you will pay significantly more tax in retirement. Use the Spousal RRSP today to level the playing field and keep the CRA out of your pocket.

General Advice Warning: The information provided in this article is based on CRA rules for the 2026 tax year. The attribution rules are complex (e.g., if you contribute even $1 in the 3-year window, it triggers attribution on withdrawals up to the total contributed amount). Always consult a Certified Financial Planner (CFP) or tax accountant to plan your contribution and withdrawal schedule carefully.
