Owning a rental property in Canada can generate solid passive income — but it also creates a filing obligation that trips up landlords every year. Whether you rent out a basement suite, a condo, or a vacation property on Airbnb, the CRA expects you to report every dollar and document every deduction. This guide walks through everything you need to know about rental income tax in Canada for the 2025 tax year, including Form T776, allowable deductions, short-term rental rules, and the audit triggers that put landlords on the CRA's radar.
Rental income is broader than the monthly rent cheque. Under the Income Tax Act, you must report all amounts received from a rental property, including:
All of this flows onto Form T776, Statement of Real Estate Rentals, which you file with your personal T1 return. Each property is reported separately, and you must keep records for at least six years in case of a CRA review.
The tax advantage of owning rental property lies in the deductions. The CRA allows you to subtract reasonable expenses incurred to earn rental income. Here is the full list:
A common mistake is deducting the full mortgage payment. Only the interest qualifies. If your monthly payment is $2,400 and $900 of that is principal, you may only deduct $1,500.
The CRA draws a firm line between a current expense (deductible in full this year) and a capital expenditure (added to the property's cost base and depreciated over time).
A repair restores the property to its original working condition — patching a roof leak, replacing a broken furnace, repainting walls. These are deductible immediately.
An improvement upgrades the property beyond its original state — finishing a basement, adding a new bathroom, installing central air where none existed. These must be capitalised and depreciated, typically under CCA Class 1 at 4% per year on a declining balance.
Example: You replace ten worn-out windows with similar-sized standard windows — that is a repair. You replace those windows with triple-pane energy-efficient units and add skylights — that is an improvement.
Residential rental buildings fall under CCA Class 1, which allows a 4% deduction on the declining balance each year. Only the building qualifies — not the land. The half-year rule limits your claim to 2% in the first year of ownership.
While CCA can shelter rental income in profitable years, most landlords avoid claiming it for one important reason: recapture. When you eventually sell the property, any CCA you claimed is added back to your income in full in the year of sale. If you claimed $40,000 in CCA over the years and sell the property at a gain, that $40,000 is fully taxable as recaptured depreciation — on top of the capital gain. For a long-hold property in a rising Calgary market, this can create a significant and unexpected tax bill.
CCA also cannot be used to create or increase a net rental loss; it can only reduce net rental income to zero. This limits its usefulness as a loss-generating strategy.
When a property is jointly owned, each co-owner reports their share of income and expenses on a separate T776. The split follows the legal ownership percentage, not a chosen allocation. Spouses cannot arbitrarily assign 100% of the income to the lower-income earner to save tax.
The attribution rules under the Income Tax Act also apply. If you transfer or loan property to a spouse or minor child to shift income, the CRA attributes that income back to you. Proper planning — including loans at the CRA's prescribed rate — is required to avoid attribution.
Converting a property from personal use to rental (or vice versa) triggers a deemed disposition at fair market value on the date of change. This means you are treated as if you sold and immediately reacquired the property at its current value — creating a potential capital gain or recaptured CCA even though no actual sale occurred.
There is one important exception: the four-year principal residence election under subsection 45(2). If you move out and begin renting your home, you can elect to continue treating it as your principal residence for up to four years, deferring the deemed disposition. This election requires that you not claim CCA during that period and that you do not designate another property as your principal residence. This strategy is particularly valuable for Calgarians who relocate temporarily for work and intend to return to their home.
Short-term rentals come with two layers of additional tax complexity.
If your annual short-term rental revenue exceeds $30,000, you are required to register for and collect GST. This threshold applies across all your commercial activity combined — not just one property. Residential rentals of one month or longer are exempt from GST, but nightly or weekly rentals are taxable supplies. Failure to collect and remit GST can result in assessments, interest, and penalties.
Beginning with the 2024 tax year, a significant new rule applies to short-term rental operators. If your property is located in a province or municipality that prohibits or restricts short-term rentals and you are not compliant with those rules, you cannot deduct any expenses against your short-term rental income. You must report the gross revenue, but deductions — including mortgage interest and property taxes — are denied. This change was introduced by the federal government to discourage non-compliant short-term rentals in housing-constrained markets. Even if your rental generates a loss, that loss is not claimable if you are operating outside local licensing requirements.
Practical takeaway: If you operate an Airbnb in a city with short-term rental bylaws, obtain the required licence and keep proof of compliance with your tax records.
The CRA cross-references T776 data with land title registries, platform income reports, and mortgage records. Common triggers include:
Maintaining a dedicated folder — physical or digital — for each property with receipts, lease agreements, mortgage statements, and a mileage log is the simplest way to survive a review.
Rental income tax touches property law, income tax, GST, and estate planning all at once. Getting the T776 wrong costs money — either through missed deductions or avoidable penalties. The team at Swift Accounting Calgary works with landlords across Alberta to prepare accurate T776 filings, structure co-ownership arrangements, and navigate the short-term rental rules introduced in 2024. Whether you own one rental suite or a small portfolio, professional guidance pays for itself.

Yes. There is no minimum rental period that exempts income from reporting. If you rented your cottage for two weeks in July and collected $3,000, that amount must be reported on Form T776. You may deduct a proportionate share of expenses for the rental period.
No. Only the interest component of your mortgage payment is deductible. Principal repayment reduces your debt but is not a cost of earning rental income under the Income Tax Act. Review your annual mortgage statement from your lender — it breaks down interest paid for the calendar year.
Genuine net rental losses — where expenses legitimately exceed income — can generally be applied against other income such as employment earnings, reducing your overall tax bill. However, the CRA may question a property with chronic losses and no reasonable expectation of profit. If losses result from non-compliant short-term rental activity in a restricted municipality, they are now specifically denied under the 2024 rules.
Yes, but the calculation is proportional. You allocate expenses — mortgage interest, property taxes, utilities, insurance — based on the percentage of floor space rented. Renting a room that represents 20% of your home means you may deduct 20% of eligible expenses against that rental income. Note that claiming CCA on your principal residence can jeopardise your principal residence exemption, so most homeowners skip it.
