Maximize Your Tax Savings While Growing Your Wealth: A Guide to Investment Loan Interest Tax Deductibility

Posted in Taxation by Goran Ogar - December 13, 2024

What Makes Interest on Investment Loans Tax Deductible?

1. Interest Must Be Paid or Payable

To qualify for a deduction, there must be a legal obligation to pay the interest. This ensures the lender can enforce repayment of the loan principal and interest.

  • For Individuals (Cash Method): Deduct interest in the year it is paid.
  • For Businesses (Accrual Method): Deduct interest in the year it becomes payable, even if not yet paid.

đź’ˇ Pro Tip: Compound interest is only deductible when actually paid. Plan repayment schedules accordingly to maximize deductions.

2. Interest Costs Must Be Reasonable

Interest costs must reflect market conditions and should be comparable to rates offered to borrowers with similar credit risks. The Canada Revenue Agency (CRA) can deny deductions if the interest is deemed excessive.

Example: Avoid Overcharging Yourself

If you borrow funds from your own corporation at an inflated interest rate, the CRA may disallow the deduction. Always use market-aligned interest rates to ensure compliance.

3. Interest Must Be Incurred to Earn Income

The loan must be used for generating income, such as dividends or interest. Capital gains alone do not qualify as income for deductibility purposes. However, if your investment aims to produce income in addition to capital growth, you may still deduct the interest.

Example: Borrowing to Invest in Dividend Stocks

If you borrow $100,000 to purchase dividend-paying stocks, the expectation of earning dividends makes the interest deductible, even if the stock price appreciates.


Common Deductibility Limitations to Watch For

Non-Deductible Uses of Borrowed Funds

Interest is not deductible if funds are used to:

  • Earn exempt income.
  • Purchase life insurance policies.
  • Contribute to registered plans like RRSPs, TFSAs, or RESPs.

Exception: Segregated Funds

Interest on borrowed money used to purchase non-registered segregated fund contracts is deductible, as outlined in Subsection 20(2.2) of the Income Tax Act.


Advanced Strategies for Maximizing Interest Deductibility

1. Handling Return of Capital

When investments distribute a return of capital that is used for personal purposes, the CRA considers this a reduction in the loan’s income-generating purpose. Adjust your deductions proportionately.

Practical Advice

Reinvest distributions from your investments to maintain the link between the loan and income generation, preserving your interest deductibility.

2. Deducting Interest on Disappearing Investments

If your borrowed money no longer generates income because the investment is sold or loses value, you may still deduct the interest. Section 20.1 of the Income Tax Act allows this if the proceeds are applied to reduce the loan.

Example: Deducting Interest After a Stock Sale

Suppose you borrowed $50,000 to purchase shares that are sold for $30,000. You can still deduct interest on the remaining $20,000 loan balance if the proceeds were used to reduce the debt.

3. Importance of Tracing Funds

Accurate record-keeping is critical for maintaining interest deductibility. Borrowers must trace the use of borrowed funds to eligible purposes.

Tips for Clear Tracing:

  • Use separate accounts or dedicated credit lines for investment loans.
  • Avoid commingling borrowed funds with other sources of cash to ensure clarity.
