Grandparent Gifting Money to a Grandchild in Canada: Tax Attribution Rules

You want to help your grandchild financially — maybe set aside some savings, open an investment account, or simply give them money for their future. Canada doesn't tax gifts the way some countries do, but there's a catch that trips up many grandparents: the tax attribution rules under Section 74.1 of the Income Tax Act.

What Tax Attribution Means for Grandparents

When you give or lend money to a related minor (anyone under 18), the CRA doesn't let you shift investment income to the child's lower tax bracket. Instead, any investment income earned on that gift — interest, dividends, and certain other returns — is "attributed back" to you, the grandparent, and taxed on your return.

This is Section 74.1(2) of the Income Tax Act. It applies whenever a person transfers or lends property to a related minor, directly or through a trust. Since grandchildren are related minors, any investment income from money you give them gets added to your taxable income, not theirs.

The rule is designed to prevent income-splitting — the strategy of parking money in a child's name to pay tax at their lower rate. The CRA closes that door for family members.

What Gets Attributed and What Doesn't

Not all types of returns are treated the same:

Attributed back to you (taxed on your return):

• Interest income from savings accounts or GICs funded by your gift
• Dividend income from stocks or mutual funds purchased with your gift
• Rental income from property transferred to a minor

Not attributed (taxed in the child's hands or tax-free):

• Capital gains on investments purchased with your gift — these are taxed in the child's name, which often means little or no tax given their low income
• Income earned on reinvested income (second-generation income) — once the original gift generates income and that income is reinvested, the returns on the reinvested income belong to the child

This distinction matters. If you give your grandchild $5,000 and it earns $200 in interest, you pay tax on that $200. But if the $200 is reinvested and earns $10, the $10 is the child's income.

How This Affects RESPs and the Canada Learning Bond

Registered Education Savings Plans follow different rules, and this is where things work in your favour.

Money contributed to an RESP grows tax-sheltered inside the plan. When the beneficiary (your grandchild) eventually withdraws it for post-secondary education, the investment growth and government grants are taxed in the student's hands — typically at a very low rate because most full-time students have little income.

Section 74.1 attribution does not apply inside an RESP. The plan's tax-sheltered status overrides the general attribution rules. This makes an RESP one of the cleanest ways for a grandparent to help a grandchild financially without creating a tax headache.

If you're raising your grandchild and receiving the Canada Child Benefit, the Canada Learning Bond adds up to $2,000 to the RESP with zero contributions required from you. The CLB eligibility is based on the primary caregiver's income — and if you're the primary caregiver on a modest income, the child likely qualifies.

One structural note: grandparents can open an Individual RESP for a grandchild. A Family RESP can name multiple beneficiaries who are each related to the subscriber by blood or adoption, but a family plan can receive the Canada Learning Bond only when all beneficiaries are siblings. If you are saving for multiple grandchildren who are not siblings, separate Individual RESPs may be needed to receive the CLB for each child.

Cash Gifts With No Investment Component

If you're simply giving cash to help with day-to-day expenses — groceries, school supplies, clothing, sports fees — there's no investment income being generated, so attribution doesn't apply. Canada has no gift tax on cash transfers between family members.

The issue only arises when the money is invested and generates a return. Handing your grandchild $500 for their school trip doesn't trigger anything with the CRA.

Strategies That Work Within the Rules

If you want to give money that will grow for your grandchild's future, a few approaches minimize or eliminate attribution:

• RESP contributions — tax-sheltered, no attribution, plus government grants. Best option for education savings.
• Gifts invested in growth assets — because capital gains aren't attributed, investments that produce growth rather than interest or dividends shift the tax to the child's (typically nil) bracket.
• Canada Learning Bond — if you're the primary caregiver and qualify by income, the government deposits money into the RESP with no contribution needed from you.
• Informal trust with capital-gains-only investments — an in-trust account holding equity index funds can produce capital gains (not attributed) rather than interest (attributed). This requires careful record-keeping.

What This Means for Kinship Caregivers

If you're raising a grandchild on a pension or fixed income, the money you're spending on the child is already stretched. The last thing you need is an unexpected tax bill because the CRA attributed investment income from a well-intentioned gift.

The safest approach is to keep gifts for daily needs as cash (no tax implications) and route long-term savings through an RESP where attribution doesn't apply and government grants multiply your contributions.
