One of the most common questions Canadian homeowners have about HELOCs is whether the interest is tax deductible. The answer is nuanced and entirely depends on how you use the borrowed funds — not where the money comes from.
Under Section 20(1)(c) of the Income Tax Act, interest is deductible if the borrowed money is used for the purpose of earning income from a business or property. The CRA cares about what you do with the money, not what type of loan you used to get it.
The CRA requires that there be a reasonable expectation that the investment will generate income. This means purely speculative investments (like buying cryptocurrency with the intent only of capital gains) may not qualify, while dividend-paying stocks or rental properties clearly do.
Key CRA interpretation: the investment must have a potential for income, not just capital appreciation. Dividend stocks qualify. Growth-only stocks are a grey area. Consult a tax professional if you're unsure about your specific investments.
The Smith Manoeuvre is a Canadian tax strategy that converts non-deductible mortgage interest into deductible HELOC interest over time. Here's the basic loop:
Over 20–25 years, this strategy can save hundreds of thousands in taxes while building a substantial investment portfolio.
The CRA requires you to be able to trace borrowed funds directly to income-earning investments. This means:
If you mix funds — for example, withdrawing $50,000 from your HELOC and using $30,000 for investments and $20,000 for a vacation — only the investment portion is deductible, and you must prove the allocation.
Using a HELOC to purchase a rental property is one of the clearest cases for interest deductibility. The rental income clearly constitutes "income from property." You can deduct:
The deduction is claimed on your Schedule T776 (Statement of Real Estate Rentals) or as a carrying charge on Schedule 4.
You must prorate. Only the portion of interest attributable to income-earning use is deductible. Keep separate draws clearly documented. If you draw $100,000 and invest $70,000 while spending $30,000 personally, only 70% of the interest is deductible.
| Use of HELOC Funds | Interest Deductible? | Where to Claim |
|---|---|---|
| Dividend stocks | Yes | Schedule 4 (carrying charges) |
| Rental property | Yes | T776 (rental income) |
| Business investment | Yes | T2125 (business income) |
| Primary home renovation | No | Not deductible |
| Vacation/personal spending | No | Not deductible |
| RRSP/TFSA contributions | No | Not deductible |
Note: RRSP contributions are not deductible because the RRSP account shelters income — you can't claim the interest as a deduction when the investment income itself isn't taxable.
Stop paying monthly bank fees while you figure out your HELOC strategy. KOHO gives Canadian homeowners a no-fee account with cash back on spending. Use code 45ET55JSYA for a sign-up bonus.

No. TFSA contributions are personal savings, not income-earning investments in the CRA's view. Interest on funds used for TFSA contributions is not deductible.
Absolutely yes. The Smith Manoeuvre involves complex tax planning. An accountant or tax advisor familiar with the strategy can ensure you set it up correctly to maximize deductions and satisfy CRA tracing requirements.
