How Can Spouses Share Income Properly?

Spousal RRSPs, pension income splitting and the limits set by the attribution rules

Scott Tang, CPAUpdated 2026-11-052026 rules4 min read

In Canada, tax is filed by individual, and the rates are progressive. When one spouse earns a lot and the other earns little, the same total family income usually attracts less tax when it is split between two people than when it is all in one person's hands. But you can't simply transfer money to your spouse — under the attribution rules, the income earned on money you transfer is still taxed in the hands of the person who gave it.

Individual filing

Each spouse files their own return, and the rates are progressive

Attribution rules

If you simply give your spouse money to invest, the income is generally taxed back to the person who gave it

50%

Up to half of eligible pension income can be split with your spouse

This year + prior two

Spousal RRSP: if contributions were made in the year of withdrawal or in the two calendar years before, the withdrawal may be taxed back to the contributor

Common arrangements

One spends, one saves
The higher-earning spouse pays the household expenses and the taxes, and the lower-earning spouse saves and invests their own income — the simplest approach, with no loan to set up, but keep good records of each person's income, transfers and the money each puts into investments.
TFSA gifts are fine
Give your spouse money to fill up their own TFSA; the income earned inside it is not attributed.
Pension income splitting in retirement
Only eligible pension income can be split, and both spouses must be Canadian residents. Payments from an employer pension plan generally qualify at any age; RRIF payments and similar income generally from age 65. CPP can't be split on Form T1032, but you can apply separately to share your CPP pensions as a couple.
Spousal RRSP
The higher-earning spouse contributes and takes the deduction; later, the lower-income spouse withdraws the money, evening out retirement income between the two of you.
Prescribed rate loans
See "Lending to Family Members to Invest: Prescribed Rate Loans" in this series.

Points to watch

Keep the source of funds clear
Separate accounts, separate money and clear records for each of you. Investment income in a joint account is generally split according to how much each person put in.
Family corporations have their own rules
Dividends that a private corporation pays to a spouse or children are subject to the tax on split income (TOSI), so they may not be taxed at the lower rate.
Minor children
If you give a child under 18 money to invest, interest and dividends are also attributed back to you (capital gains generally are not).
Separation and divorce
The attribution rules change, and there are specific rules for dividing property.
