Prescribed Rate Spousal Loans: Canadian Income Splitting Playbook
How high-earning Canadians legally shift taxable investment returns to a lower-earning spouse or family trust under CRA Income Tax Act Section 74.5(2).
Canadian married or common-law couples with a significant disparity in taxable income (e.g. one spouse in the 45%–53% bracket and the other in the 0%–25% bracket) and non-registered investable capital exceeding $100,000.
The CRA Attribution Trap (ITA Sections 74.1 & 74.2)
In Canada, unlike the United States where married couples can file joint tax returns, taxation is strictly individualized. Each spouse files an independent tax return with separate marginal tax brackets. Consequently, high-earning couples face a severe tax penalty: when the high-earner receives an annual bonus or sells assets, any investments purchased in non-registered accounts generate dividends, interest, and capital gains that are taxed at their top marginal tax rate—often exceeding 50% to 53.53%.
A natural instinct is for the high-earning spouse to simply give or transfer funds to the lower-earning spouse to invest in their name. The Canada Revenue Agency (CRA) explicitly outlaws this.
Under the anti-avoidance Attribution Rules in Sections 74.1 and 74.2 of the federal Income Tax Act (ITA):
CRA Statutory Rule: If an individual transfers or lends property (directly or indirectly) to their spouse or common-law partner, all income (dividends, interest) and all capital gains/losses derived from that property are attributed back to the transferor and taxed at the transferor's higher marginal rate as if they had earned it themselves.
Even if the brokerage account is titled exclusively in the lower-earning spouse's name, on audit the CRA traces the source of funds back to the high-earner's bank account, recalculates taxes, assesses interest, and slaps failure-to-report penalties.
The Statutory Safe Harbor: ITA Section 74.5(2)
Fortunately, Parliament provided an explicit statutory exemption in Section 74.5(2) of the Income Tax Act. Attribution rules do not apply to a loan made between spouses if two strict conditions are met:
- The Prescribed Rate Condition: The loan must bear interest at a rate at least equal to the CRA's prescribed interest rate in effect at the time the loan was executed.
- The Timely Payment Condition: The borrower must actually pay the annual interest to the lender no later than January 30th of the following calendar year.
A critical legal feature of Section 74.5(2) is that the prescribed rate in effect on the date the promissory note is signed remains locked in permanently for the entire life of the loan. Even if the CRA prescribed rate climbs to 6% or 7% in future years, your loan rate never increases as long as the original loan remains outstanding.
How the wealth arbitrage works:
- The high-earning spouse lends $300,000 to the lower-earning spouse at the CRA prescribed rate (e.g. 3%).
- The lower-earning spouse invests the $300,000 in a diversified global ETF portfolio yielding an expected 7% compound total return ($21,000/yr).
- The lower-earning spouse pays 3% annual interest ($9,000) to the high-earner before January 30th.
- The $9,000 interest paid is a tax-deductible investment expense for the lower-earning spouse (Line 22100 - Carrying charges), offsetting $9,000 of investment income.
- The high-earning spouse reports the $9,000 interest as taxable interest income (Line 12100).
- The remaining $12,000 in net investment growth ($21,000 − $9,000) is taxed 100% in the hands of the lower-earning spouse at their lower marginal tax bracket (or 0% if within their basic personal amount), completely bypassing attribution!
The Fatal January 30th Rule: Zero Grace Period
The single most dangerous trap in Canadian tax planning is the January 30th payment deadline. Under Section 74.5(2)(b), the annual interest for the preceding calendar year must be received by the lender on or before January 30th.
If the interest payment is made on January 31st or February 1st—even by accident, bank processing delay, or medical emergency—the Section 74.5(2) exemption is permanently and irreversibly broken. The attribution rules will apply for that year and every single future year that the loan exists. You cannot fix it by paying late with interest. The only remedy is to completely unwind the loan, liquidate the investments (triggering capital gains), return the capital, and execute an entirely new loan agreement at the prevailing prescribed rate.
CRA Audit Defense Protocol:
- Actual Cash Transfer: Never use a bookkeeping journal entry or promissory note offset. The lower-earning spouse must physically transfer funds from their personal bank account to the lender's personal bank account.
- Date Stamp: Execute the transfer on or before January 15th of each year to ensure the bank clears and records the funds before January 30th.
- Documentation: Keep a PDF copy of the interac e-Transfer confirmation or cleared cheque alongside the written promissory note in your permanent tax binder.
- Tax Reporting: The high-earner reports interest income on Line 12100. The low-earner claims the interest deduction on Line 22100 (Carrying charges and interest expenses) on Schedule 4.

Prescribed Rate Loans to Family Trusts (Funding Children's Expenses)
Beyond spousal loans, sophisticated Canadian families utilize prescribed rate loans made to a discretionary family trust for minor children or grandchildren:
- The Child Tax Exemption Arbitrage: Minor children pay $0 in income tax on their first ~$15,000 of taxable income each year due to the Basic Personal Amount.
- Bypassing the "Kiddie Tax" (TOSI): While the Tax on Split Income (TOSI) rules in ITA Section 120.4 shut down private corporate dividends to minor children, portfolio income (interest and foreign dividends) generated in a trust funded by a bona fide prescribed rate loan is exempt from TOSI.
- Eligible Direct Expenses: The trust can allocate taxable investment income to the minor children and use those funds directly to pay for their private school tuition, tutoring, summer camp fees, or sports academies—paying for living costs with 0% tax dollars instead of the parents' 53% after-tax income.
Promissory Note & Audit-Proof Execution Checklist
- Formal Written Promissory Note: Draft a formal, legally binding loan agreement specifying: date of issuance, principal sum, repayment on demand, and the exact CRA prescribed interest rate. Both spouses must sign in the presence of an independent witness.
- Sole Beneficiary Brokerage Account: The borrowed money must be deposited into a brand new, segregated non-registered investment account in the sole name of the borrowing spouse. Never co-mingle loan funds with joint or pre-existing assets.
- Automated Calendar Reminder (January 10): Set a recurring annual calendar notification on January 10th to initiate the inter-bank transfer before the January 30th cutoff.
- File Proper Tax Schedules: The lender reports interest received on Line 12100. The borrower completes Schedule 4, entering interest paid on Line 22100 (Carrying charges and interest expenses) referencing the lender's name and loan purpose.
- Permanent Retention: Retain the promissory note, bank transfer receipts, and annual statements indefinitely. Attribution audits can be initiated by the CRA years into the future.
