Income splitting is one of the most underused tax strategies for Canadian couples. Here's a plain-language breakdown of the strategies that actually work.
Spousal RRSP: The Foundation
A spousal RRSP is registered in your spouse's name but funded with your contribution room. You get the deduction; your spouse owns the account and is taxed on withdrawals in retirement at their lower marginal rate. Over decades of retirement, the combined tax saving can be significant. Key rule: withdrawals within three calendar years of a contribution trigger attribution back to the contributing spouse - plan the wind-down of spousal RRSP contributions in advance of retirement to avoid this.
Pension Income Splitting
After age 65, up to 50% of eligible pension income (RRIF withdrawals, life annuity, registered pension payments) can be reported by the lower-income spouse for tax purposes. This is one of the simplest and most valuable tax strategies available to retired Canadian couples - reducing the combined household tax bill by keeping both incomes in lower marginal rate brackets.
The Prescribed Rate Loan Strategy
If one spouse has significant non-registered investment assets and the other has a lower income, a prescribed rate loan allows the higher-income spouse to lend funds to the lower-income spouse at CRA's prescribed rate. The lower-income spouse invests the funds; income above the prescribed rate is taxed in their hands, not attributed back. The loan must be documented formally, and interest must be paid to the lender by January 30 each year without fail.
TFSA Contributions for the Lower-Income Spouse
Each Canadian resident 18 or older accumulates TFSA room regardless of income. The higher-income spouse can gift funds to the lower-income spouse for TFSA contribution - without the attribution rules applying to TFSA growth and withdrawals, since TFSA income is already tax-free. This is one of the cleanest income-shifting strategies available.
Salary to a Spouse in a Family Business
If one spouse operates a business, paying a reasonable salary to the other for work actually performed is legitimate income splitting and deductible against business income. CRA will scrutinize compensation that isn't reasonable for the work performed, so the amount must be defensible. Coordinating these strategies requires modelling the household tax position over time. Our Clarity Tools can help surface the most valuable opportunities for your specific situation.
