Canada Rental Property Tax Guide: Deductions, CCA, and Reporting Rental Income

Yes — the interest portion of your rental property mortgage payments is fully deductible on Form T776 as a carrying charge. The principal repayment portion is not deductible. To maximize deductibility, keep your rental property mortgage separate from your personal mortgage. The Smith Manoeuvre is a strategy to convert personal mortgage debt (non-deductible) into investment debt (deductible) by using a readvanceable mortgage — but it requires careful structuring and carries risk. Note: if you have a HELOC secured against your primary home and use the proceeds to purchase or renovate a rental property, the HELOC interest is deductible as a rental expense (the purpose of the borrowing, not the security, determines deductibility). See the CRA rental expenses guide for full rules.

If you manage your rental properties from a dedicated office space in your home, you may be able to deduct a portion of home office expenses as a rental expense — but only for the management-related portion, and only if you meet CRA's criteria: (1) the space must be used exclusively and regularly for rental management; (2) you can deduct a pro-rated share of rent or property taxes, utilities, and maintenance based on office square footage as a percentage of total home area; (3) home office expenses for rental management cannot create a rental loss — they can only reduce income to zero. This is a gray area and is frequently scrutinized by CRA. Consult a tax professional before claiming. See the CRA T4036 Rental Income guide for the complete expense rules.

This distinction is critical for tax deductibility: (1) Current (deductible) expenses: restore the property to its original condition; incurred regularly; relatively small cost. Examples: patching a roof (not replacing it), fixing a broken appliance, repainting, replacing a broken window, cleaning. Fully deductible in the year incurred; (2) Capital expenses: add to the value of the property, extend its useful life, or convert it to a different use. Examples: adding a bathroom, replacing the entire roof, installing new HVAC, finishing a basement. Capital expenses are added to the adjusted cost base (ACB) of the property and eligible for CCA — not deducted immediately. The line between current and capital is often blurry. CRA considers cost, nature of the work, and whether the work creates a new asset or restores an existing one. The CRA current vs capital expenses guide provides the official test.

CRA focuses on rental income because under-reporting is common. Common audit triggers: (1) Rental losses every year: CRA may question whether the property has a reasonable expectation of profit; (2) Expenses significantly above industry norms: claiming 80%+ of gross rental income as expenses; (3) Mixed personal/rental use: renting a cottage seasonally while using it personally — only proportional rental use periods qualify; (4) Mortgage interest on a rental property higher than rental income alone could support: may indicate the property was not acquired for income purposes; (5) Short-term rentals (Airbnb): platform-reported income that doesn't match your return; (6) Principal residence exemption claims on former rental properties without proper documentation. Keep all records 6 years from the end of the related tax year. See the CRA rental property compliance page.

Short-term rental income (rentals under 30 days) is generally treated as rental income on T776, not active business income, unless you provide hotel-like services (daily cleaning, linen service, meals). Tax implications specific to short-term rentals: (1) GST/HST: short-term accommodation rentals under 30 days are taxable supplies subject to GST/HST — if your short-term rental income exceeds $30,000 in four consecutive calendar quarters, you must register for and collect GST/HST; (2) Platform reporting: Airbnb and Vrbo report income to CRA under digital platform reporting rules; (3) Municipal regulations: many cities (Toronto, Vancouver, Ottawa) require short-term rental permits and restrict STR to principal residences only — operating illegally can disqualify the property from principal residence protection; (4) Provincial sales tax: some provinces (BC, ON, QC) levy a provincial tax on short-term rentals collected by platforms. See the CRA GST/HST short-term accommodation guide.

In Canada, there is no estate tax or inheritance tax, but death triggers a deemed disposition at fair market value. Your estate is treated as if it sold all capital property at FMV on the date of death. For a rental property: (1) any unrealized capital gain (FMV minus adjusted cost base) is realized and taxed in the terminal return at the capital gains inclusion rate (currently 50% of the gain is included in income; 2024 budget proposed 2/3 inclusion rate for gains above $250,000 — verify current rules); (2) any recaptured CCA (UCC is less than original cost) is fully included in income; (3) property can be rolled over to a surviving spouse/common-law partner at cost — deferring the tax until the surviving spouse disposes of the property. Proper estate planning (insurance, holding corporations, spousal trusts) can minimize taxes on rental property at death. The CRA guide for legal representatives covers deemed dispositions at death.
