Prescribed Rate Loans in Canada: Income Splitting with a Lower-Income Spouse

A prescribed rate loan allows a high-earning spouse to lend money to a lower-earning spouse at the Canada Revenue Agency (CRA) official interest rate. This legally shifts investment income to the lower tax bracket, saving families thousands in taxes. You must pay the interest by January 30 every year to comply.

Navigating the Canadian tax system can feel overwhelming, especially when one spouse earns significantly more than the other. 📈 Families in Toronto, Ontario or Calgary, Alberta often find that the high-earning spouse is taxed at the highest marginal rate, sometimes exceeding 50%. If this high earner invests extra cash, the dividends and interest are also taxed at that top rate, leaving less money for the family’s future.

Generally, the CRA uses “attribution rules” to prevent you from simply giving money to your spouse to invest at their lower tax rate. If you give a gift of cash to your partner, the CRA will attribute the investment income back to you. However, establishing a prescribed rate loan is a legally approved method to bypass these attribution rules. By formally lending the money at the CRA’s prescribed interest rate, the lower-earning spouse can invest the funds, pay back the modest interest, and keep the remaining profits taxed at their much lower rate.

Step-by-Step Process in Canada

Whether you live in Vancouver, British Columbia or Halifax, Nova Scotia, the rules governing prescribed rate loans are strictly federal and managed by the CRA. 📝 Setting up this arrangement requires careful planning and strict adherence to specific steps to ensure the CRA respects the loan.

Step 1: Draft a Formal Promissory Note

You cannot simply transfer money and call it a loan; you must have a legally binding agreement. Most applicants choose to hire a local law firm to draft a Promissory Note. This document must state the principal loan amount, the exact CRA prescribed interest rate at the time the loan is made, and the repayment terms. The rate is locked in for the entire life of the loan, regardless of future CRA rate hikes.

Step 2: Transfer the Funds

Once the document is signed and witnessed, the higher-earning spouse must transfer the funds. 🏨 It is critical to maintain a clear paper trail. Transfer the money from an account solely in the high earner’s name to an investment account solely in the lower earner’s name. Avoid using joint accounts for this transfer, as it can confuse the CRA and trigger an audit.

Step 3: Invest the Loaned Funds

The lower-income spouse must use the loaned money strictly for the purpose of earning income. This usually means buying dividend-paying stocks, mutual funds, or rental properties. You cannot use a prescribed rate loan to pay off personal credit card debt or buy a personal vehicle, as these do not generate taxable investment income.

Step 4: Pay the Annual Interest by January 30

This is the most critical step of the entire process. 📅 The borrowing spouse must pay the interest owed to the lending spouse no later than January 30 of the following year. The payment must be made using the borrower’s own funds. If you miss this deadline by even a single day, the CRA attribution rules will permanently apply to this loan, ruining the tax strategy forever.

Step 5: File Your Tax Returns Correctly

When tax season arrives, both spouses must report the transaction properly. The high-earning spouse must report the interest received as taxable income. The lower-earning spouse can claim a deduction for the interest paid to carry an investment. Furthermore, the lower-earning spouse reports all the investment gains and dividends on their tax return, paying taxes at their lower marginal rate.

How Much Does it Cost in Canada?

Setting up this strategy involves some upfront and ongoing costs, but the long-term tax savings usually far outweigh the expenses. 💵 Here is a general breakdown of costs in Canadian dollars (CAD):

ServiceEstimated Cost (CAD)Description
Lawyer / Law Firm$500 – $1,500Legal fees to draft a legally binding Promissory Note that satisfies CRA requirements.
Accountant (CPA)$300 – $800Annual fees to properly calculate the interest, file the correct schedules, and optimize returns.
Annual Interest PaymentVariesDepends on the loan size and the locked-in CRA rate (e.g., a $100k loan at 5% requires $5,000 paid yearly).

How Long Does the Process Take?

Drafting the agreement and transferring the funds can usually be completed within 1 to 3 weeks. ⏳ However, the tax strategy itself is designed to be a long-term commitment. A prescribed rate loan has no mandatory end date; it can last for decades. The lower-earning spouse simply continues to pay the interest by January 30 each year. If the family decides to end the strategy, the borrower simply liquidates enough investments to repay the principal loan amount back to the lending spouse.

Frequently Asked Questions (FAQ)

What happens if the CRA prescribed interest rate changes?

The interest rate is locked in at the time the loan is executed. If the CRA rate goes up in the future, your loan remains at the lower original rate. If the CRA rate drops significantly, you may choose to repay the old loan and issue a new one at the lower rate.

Can I use a prescribed rate loan to buy a family home?

No. To deduct the interest on your taxes and make the strategy work, the CRA requires the funds to be used specifically for earning income, such as buying stocks, bonds, or a rental property. A primary residence does not generate taxable income.

What if I miss the January 30 interest payment deadline?

If the deadline is missed, the CRA attribution rules will apply for that year and all future years. The investment income will be taxed in the hands of the high-earning spouse, effectively destroying the purpose of the loan.

Can a prescribed rate loan be used for a trust?

Yes. Many high-net-worth families lend money at the prescribed rate to a family trust for the benefit of their children or grandchildren. This requires complex legal structuring and should be handled by a specialized tax lawyer.
