Borrowing to Invest: Is Your Interest Tax Deductible?
Borrowing to invest can help grow your portfolio and, in some cases, create a tax deduction. However, many Canadians incorrectly assume that all interest paid on investment loans is deductible. The reality is that the deductibility of interest depends on how the borrowed funds are used and whether you can support the claim with proper documentation.
The CRA Focuses on the Use of the Borrowed Funds
When determining whether interest is deductible, the Canada Revenue Agency (CRA) looks at the current use of the borrowed money. If the funds were borrowed to earn income from investments, such as dividends, interest, or rental income, the related interest may be deductible.
To support a deduction, taxpayers should generally be able to demonstrate that:
There is a genuine loan or line of credit.
They are legally required to pay the interest.
The interest rate is reasonable.
The borrowed funds were used to earn income.
The use of the funds can be clearly traced to the investment.
Why Proper Record Keeping Matters
One of the most common reasons investment interest deductions are challenged is inadequate documentation. The CRA expects taxpayers to be able to trace borrowed funds from the loan account directly to the investment.
Helpful records may include:
Loan and line of credit statements
Bank transfer records
Investment account statements
Trade confirmations
Records of dividends, interest, or rental income earned
Annual interest calculation schedules
Maintaining a separate account or line of credit for investment borrowing can make it much easier to establish this connection and defend the deduction if it is reviewed.
Mixed-Use Lines of Credit Require Extra Care
Many taxpayers use a single line of credit for both personal and investment purposes. In these situations, only the portion that relates to income-producing investments may qualify for an interest deduction.
As the balance changes through new borrowing, repayments, investment sales, and reinvestments, the deductible portion may also change. Proper tracking is essential to ensure the interest deduction remains accurate year after year.
Common Situations Where Interest May Not Be Deductible
Interest deductions are often denied when:
Borrowed funds are used for personal expenses.
The investment is intended solely to generate capital gains.
The investment earns tax-exempt income.
The interest charged is excessive or unreasonable.
Records do not clearly support the use of the borrowed funds.
It is important to remember that a loan secured against your home is not automatically deductible. The key factor is not what secures the loan, but how the borrowed money is actually used.
Be Prepared for a CRA Review
If the CRA reviews your claim, you may be asked to provide documentation showing how the borrowed money was used and how the interest deduction was calculated. Organized records can significantly reduce the time and stress involved in responding to a review.
The CRA generally recommends keeping supporting tax documentation for at least six years.
Final Thoughts
Interest on money borrowed to invest can provide valuable tax savings, but the rules are more complex than many taxpayers realize. The ability to trace the borrowed funds, maintain adequate records, and demonstrate a reasonable income-producing purpose are all critical factors in supporting the deduction.
If you are using a line of credit to invest, refinancing an existing investment loan, or have questions about the deductibility of your interest expense, professional advice can help ensure your claim is properly supported before filing your tax return.
