Overview
Mortgage interest is generally not tax-deductible for most Canadian homeowners occupying their principal residence. However, there are important exceptions and specific strategies that can allow certain homeowners and investors to deduct some or all mortgage interest from their taxable income.
Mortgage Interest Deductibility in Canada
1. Principal Residence
- Mortgage interest on a primary residence is not tax-deductible in Canada. Unlike in the United States, Canadian tax law does not allow homeowners to claim a deduction for mortgage interest on their personal home.
2. Rental and Income-Producing Properties
- Mortgage interest is fully tax-deductible on properties used to generate income, such as rental properties.
- If only a portion of the home is used to generate rental or business income (e.g., renting out a basement suite or operating a home office), you can deduct a proportional amount of interest related to the income-producing part.
- These deductions are claimed on Form T776 (Statement of Real Estate Rentals) for rental income, or Form T2125 for business or professional activities.
Table: Deductibility by Property Use
| Property Use | Mortgage Interest Deductible? |
|---|
| Principal residence (personal use) | No |
| Entirely rental property | Yes |
| Partial rental or home office use | Partially (pro-rata basis) |
3. Making Personal Mortgage Interest Deductible (“Smith Manoeuvre”)
- While not typical, Canadians can use strategies such as the Smith Manoeuvre to convert non-deductible mortgage debt into deductible investment loan interest.
- This involves borrowing against the equity in your home (often via a readvanceable mortgage or HELOC) and investing the borrowed funds in income-producing assets.
- Interest paid on funds borrowed to earn investment income (such as dividends or interest, but not capital gains) is tax-deductible.
- This strategy is complex and requires careful planning to comply with CRA requirements. Professional advice is highly recommended before implementing it.
4. Key CRA Requirements for Deductibility
To qualify for a deduction on interest paid, the following must apply:
- Funds must be borrowed with the intent to earn income from a business or property (not just capital gains).
- The interest must be reasonable relative to market rates.
- There must be a legal obligation to pay the interest.
- Interest must be paid or accrued in the year the deduction is claimed.
5. Provincial Variations
- Mortgage interest tax deductibility rules are set federally and do not vary by province. However, some provinces may offer additional property-related credits or rebates, but these are not related to mortgage interest specifically.
6. Recommendations and Next Steps
- Landlords and investors: Track mortgage interest payments and claim the deduction on your annual tax return (Form T776).
- Homeowners considering the Smith Manoeuvre: Consult a tax or financial advisor before proceeding.
- First-time homebuyers: While you cannot deduct mortgage interest, explore programs like the First-Time Home Buyer Incentive, RRSP Home Buyers’ Plan, and provincial rebates.
