The Anatomy of CRA Attribution Rules (Why Direct Gifting Fails)
Under Canadian tax law, gifting investment funds to a spouse or minor child triggers automatic attribution. Any dividends, interest, or rental yields generated by the gifted capital are treated as if the high-income spouse earned them. While capital gains realized by a minor child are exempt from attribution, all corporate dividends and coupon interest remain legally tethered to the donor.
To eliminate this tax drag, Section 74.5 provides a formal statutory safe harbor: if capital is transferred as a formal loan bearing interest at the CRA’s quarterly prescribed rate at the time of execution, all attribution rules are permanently disengaged for the lifetime of the loan.

Forensic Comparative Matrix: Gifting vs. Prescribed Rate Loan vs. Family Trust
| Structure | CRA Attribution Trigger | Effective Tax on $100k Yield | Jan 30 Interest Deadline | Annual Tax Savings |
|---|---|---|---|---|
| Direct Spouse Gift | 100% Attributed to High Earner | $53,500 (Ontario top rate) | N/A | $0 (Full Penalty) |
| Spousal Prescribed Loan ($1M) | Completely Disengaged | $24,100 (Blended Lower Bracket) | Mandatory (1 day late kills loan) | $29,400 / year |
| Discretionary Family Trust Loan | Disengaged (Adult Beneficiaries) | $19,300 (Split across multiple adults) | Mandatory (Strict ledger required) | $34,200 / year |
The 4 Non-Negotiable CRA Rules of Prescribed Rate Loans
1. The Fatal January 30th Interest Payment Trap
The Income Tax Act contains a lethal tripwire: the interest on the prescribed rate loan for every calendar year must be paid to the lender on or before January 30 of the following year. If the borrower pays on January 31—even by a margin of 5 minutes—the entire loan arrangement is permanently tainted. The statutory exemption is irrevocably voided, and all subsequent investment returns are attributed back to the lending spouse for all future taxation years.
2. Formal Written Promissory Note & Commercial Terms
You cannot execute an informal handshake agreement. The CRA requires a legally binding promissory note signed by both spouses specifying the loan principal, demand repayment terms, and the exact prescribed interest rate applicable at the loan’s inception date.
3. Permanent Rate Lock-In Mechanics
One of the greatest mathematical advantages of Section 74.5 is that the prescribed rate locked in at the date of loan creation remains in effect for the entire duration of the loan, regardless of whether CRA commercial interest rates rise in subsequent quarters.

4. Deductibility of Interest for the Borrower
Because the borrowed capital is deployed directly into income-producing assets (such as dividend-paying Canadian equities, index funds, or corporate bonds), the borrower is entitled to claim an interest expense deduction on Line 22100 of their T1 return, directly offsetting their taxable income.
