Income Attribution Rules: Why the CRA Claws Back Income You Tried to Shift

How the Income Attribution Rules Work

When you transfer or lend property (cash, shares, real estate, etc.) to your spouse or to a child under 18, and the transfer has the effect of reducing your taxable income, the CRA may attribute the income generated by that property back to you. In practice, those earnings appear on your return — not the recipient's. Attribution applies not only to outright gifts, but also to interest-free loans or loans made at a rate below the CRA's official prescribed rate, which is set each quarter. The underlying principle: the law presumes that if you "give" money to a related lower-income person, you're doing it to split income — and it neutralizes that advantage.

Spouses and Common-Law Partners: Both Income and Capital Gains Are Attributed

For a spouse or common-law partner, the attribution rules are the broadest:

• Investment income (interest, dividends, rent) earned on transferred property is attributed back to you.
• Capital gains realized when that property is sold are also attributed back to you.
• Attribution continues as long as you remain together. If you separate, attribution generally ceases for subsequent years.

Practical example: you gift $20,000 to your spouse and they invest it in an ETF. The dividends received and any capital gain on sale flow back to you for tax purposes — even though the money sits in their account. The hoped-for tax savings evaporate entirely.

Minor Children: Income Attributed, Capital Gains Generally Not

For a child under 18 (or a niece or nephew), the rules are partly different:

• Investment income (interest, dividends) earned on gifted or loaned property is attributed back to you.
• Capital gains realized by the child are generally NOT attributed — they remain taxable in the child's hands, often at a very low or zero rate.
• Attribution ends in the year the child turns 18.

This distinction creates a narrow planning window: if you set up an investment account for a minor child and target growth-oriented securities (with minimal dividends), future capital gains may stay in the child's hands. This is a permitted strategy, but it requires careful structuring — consult a tax professional.

Legitimate Strategies to Still Split Income in Your Family

The attribution rules close certain doors, but leave others open. Here are the main approaches that comply with the law:

• Spousal RRSP: you contribute to an RRSP registered in your spouse's name (and you claim the deduction). At retirement, withdrawals are taxed in their hands — provided you respect the three-year rule before withdrawals to avoid attribution.
• Prescribed-rate loan: you lend money to your spouse at the CRA's official prescribed rate, with a written agreement and interest paid annually by January 30. Investment income earned on those funds is then taxable in their hands, not yours. This strategy must be set up correctly from the start.
• Contributing to a spouse's or child's TFSA: gifting money for someone else's TFSA is allowed. Income earned inside a TFSA is tax-free for its holder — and the attribution rules don't apply to TFSA income because it isn't taxable in the first place.
• Paying household expenses: if you cover shared costs (groceries, rent, utilities), your lower-earning spouse can invest their own employment income — and any returns stay taxable in their hands, with no attribution, because the invested money originated with them.

What to Keep in Mind to Avoid Unpleasant Surprises

Attribution is automatic — the CRA doesn't need to prove intent. Once the conditions are met, the rules apply. Key points to remember:

• A simple interac transfer between spouses followed by an investment can be enough to trigger attribution.
• The rules apply to transfers of any property, not just cash — shares, real estate, and other assets are included.
• A prescribed-rate loan must be documented before the first interest payment — you can't fix the structure retroactively.
• For any complex income-splitting strategy, advice from a qualified accountant or tax professional is strongly recommended.

These rules aren't designed to punish families — they're designed to ensure tax is paid by the person who actually earned the income. Properly understood, they still leave room for effective planning, within the boundaries Parliament has set.
