Key takeaways
  • Rental income is reported on Form T776, with net income or loss going to line 12600 of your T1 return.
  • Reasonable expenses to earn rental income are deductible, but mortgage principal repayments are not.
  • CCA cannot be used to create or increase a rental loss.
  • CCA claimed in earlier years can come back as recapture, taxed as ordinary income, when you sell.

If you rent out a unit, a basement apartment or a whole house in Ontario, the CRA expects you to report the income and lets you deduct the costs of earning it. The details matter, especially for repairs, shared homes and depreciation.

This article covers how rent is reported, which expenses can be deducted, how capital cost allowance (CCA) works, and why claiming it can affect your tax on a later sale. Your situation may involve facts not covered here, so a lawyer or accountant can confirm the details.

How rental income is reported

Rental income from real estate is reported on Form T776, Statement of Real Estate Rentals. Gross rents are on line 8299, and the net income or loss goes to line 12600 of your T1 return.

Reporting is on a calendar-year basis, from January 1 to December 31. The accrual method is the default, and the cash method is allowed only where the results would be almost the same.

The person who owns the property reports the income or loss. Co-owners report their share in proportion to their ownership.

Expenses you can and cannot deduct

A landlord can deduct any reasonable expenses incurred to earn rental income. These include interest on money borrowed to buy or improve the property, property taxes for the period it was available for rent, and insurance premiums for the current year. Multi-year premiums are spread over the years they cover.

ItemTreatment
Mortgage interest on money borrowed to buy or improveDeductible
Property taxes while available for rentDeductible
Insurance premiumsDeductible for the current year; multi-year premiums are spread out
Repair restoring original conditionGenerally a current, deductible expense
Capital improvement giving a lasting benefitNot deductible as a repair; CCA may be claimed instead
Mortgage principal repaymentsNot deductible
Land transfer taxesAdded to the property's cost, not deducted as a rental expense
Interest on refinanced funds used for personal purposesNot deductible against rental income

Renting part of your home or below market rent

If only part of a property is rented, you can claim only the expenses that relate to the rented area. The split can be based on square metres or number of rooms, for example 3 of 12 rooms is 25%. Expenses for renting part of a property cannot be claimed if there is no reasonable expectation of profit.

If you rent below fair market value, the arrangement is treated as cost-sharing, and a rental loss cannot be claimed. This can come up when renting to family members, so it is worth asking before you file.

Capital cost allowance and the tax that can follow

CCA is the tax version of depreciation. It can generally be claimed on a rental property only once the property has become available for use. It is calculated on the declining-balance method, and you do not have to claim the maximum in any year.

The catch comes when you sell. If the class's undepreciated capital cost is negative at year-end, the excess is included in your income as recapture, taxed as ordinary income rather than a capital gain. If no property remains in the class, there may be a terminal loss, and usually 100% of a terminal loss is deductible, while only 50% of a capital loss is.

On a sale, dispositions of rental property are listed on Schedule 3, with land and building reported separately. Capital gain is proceeds of disposition minus the adjusted cost base and the outlays and expenses of the sale. One-half of a capital gain is the taxable portion under section 38 of the Income Tax Act.

What to do next

Frequently asked questions

Which form do I use to report rent?

Use Form T776, Statement of Real Estate Rentals. Gross rents are on line 8299, and net income or loss goes to line 12600 of your T1 return.

Can I deduct my mortgage payments?

Only part of them. Interest on money borrowed to buy or improve the property is deductible, but mortgage principal repayments are not.

Do I have to claim CCA?

No. You do not have to claim the maximum in any year. CCA also cannot create or increase a rental loss, and it can lead to recapture when you sell.

What if I rent a room in my own home?

You can claim only the expenses that relate to the rented area, using a reasonable split such as square metres or number of rooms. Claiming CCA on the rented area also requires that you are not designating the building as your principal residence.
