What are attribution rules in Canada?

Attribution rules prevent income splitting by attributing income back to the transferor. If you give money to your spouse or minor child to invest, the investment income is taxed in your hands, not theirs — defeating the income splitting purpose.

Can I give money to my spouse to invest?

You can, but income (interest, dividends) is attributed back to you for tax purposes. Capital gains are NOT attributed for spouse transfers. To avoid attribution, use a prescribed rate loan or contribute to a spousal RRSP.

Do attribution rules apply to adult children?

Generally no. Attribution rules don''t apply to gifts to adult children (18+). You can give money to your adult child, and any income they earn is taxed in their hands. However, if a loan is involved, fair market interest should be charged.

Attribution Rules in Canada: What You Need to Know About Income Splitting (2026)

Attribution rules are CRA’s way of preventing high-income earners from shifting investment income to lower-taxed family members. If you give your spouse $100,000 to invest, the interest and dividends are taxed in your hands, not theirs — completely defeating the income-splitting purpose. But there are several legitimate strategies to work around attribution: prescribed-rate loans to your spouse, spousal RRSPs, investing the Canada Child Benefit in your child’s name, and the often-overlooked fact that capital gains on gifts to a spouse are not attributed back. Understanding these rules is essential for any family trying to minimize their overall tax burden.

How Attribution Works: Examples

Example 1: Gift to Spouse

Scenario	Tax Result
You give spouse $100,000	—
Spouse invests in GIC earning 4%	—
Annual interest: $4,000	—
Who pays tax?	YOU (the giver)

Example 2: Gift for Minor Child

Scenario	Tax Result
You give child $20,000	—
Invested, earns $1,000 interest	—
Invested earns $500 capital gain	—
Interest taxed to	YOU
Capital gain taxed to	CHILD

Example 3: Compound Growth (Second Generation)

Scenario	Tax Result
Year 1 interest: $4,000	Attributed to you
Year 2: $4,000 reinvested earns $160	$160 taxed to spouse
Why?	Income on income not attributed

Legitimate Income Splitting Strategies

Spousal Loan at Prescribed Rate

How It Works	Details
Loan money to spouse	Formal loan agreement
Charge prescribed rate	Currently 5% (set quarterly)
Spouse invests	Earns returns
Spouse pays interest	Annually
Spouse’s income	Net of interest paid = theirs

Example:

Factor	Amount
Loan to spouse	$200,000
Prescribed rate	5%
Interest owed annually	$10,000
Spouse’s investment return (8%)	$16,000
Spouse reports	$16,000 - $10,000 = $6,000
Your interest income	$10,000
Tax savings	Lower bracket spouse pays tax on $6,000

The prescribed-rate spousal loan is the most powerful legal income-splitting tool available to Canadian families, but it requires discipline. The loan must be a genuine, documented loan with interest paid by January 30 of the following year — miss even one annual interest payment and attribution kicks in permanently. At the current 5% prescribed rate, it works best when investments earn significantly more than 5% (equities averaging 7–10%), creating a meaningful spread that’s taxed at the lower-income spouse’s rate. Lock in the prescribed rate when it’s low, because the rate at loan inception applies for the life of the loan.

The Bottom Line

Attribution rules make straightforward income-splitting through gifts almost impossible, but CRA provides several legitimate alternatives. A prescribed-rate spousal loan, spousal RRSP contributions, investing CCB in your child’s name, and paying household expenses so your spouse can invest their own income are all CRA-approved strategies that can save families thousands per year. The critical detail is documentation — keep written loan agreements, track interest payments, and clearly record who owns which investments. Without a paper trail, CRA will attribute everything back to the higher earner.
