Rental Property Expenses Canadians Forget to Claim (2026 Guide)
Published: April 2026 | Reading time: 9 min | Category: Real Estate, Tax Savings, Personal Finance
Owning a rental property in Canada comes with a surprisingly generous set of tax deductions — but most landlords only claim the obvious ones. Mortgage interest, property taxes, insurance. Done.
What they miss is often worth thousands of dollars in additional deductions every single year.
If you own a rental property in Ontario (or anywhere in Canada), this guide walks through every legitimate expense category the CRA allows — including the ones your accountant may not have mentioned.
Why This Matters More Than You Think
Rental income in Canada is taxed as regular income — meaning at your full marginal rate. At Ontario's combined federal and provincial rates, landlords earning $100,000–$150,000 total income are paying 43% on every dollar of net rental profit.
Every $1,000 in legitimate deductions you miss costs you approximately $430 in real taxes.
A landlord who forgets to claim vehicle expenses, home office costs, and a few other items commonly leaves $3,000–$8,000 in deductions on the table annually. That's $1,300–$3,440 in unnecessary tax.
The CRA allows landlords to deduct any expense that is reasonable and incurred for the purpose of earning rental income. The list is longer than most people realize.
The Basics (That Everyone Claims)
Before getting to the missed ones, here's a quick confirmation of what you should already be claiming:
- Mortgage interest — the interest portion of your mortgage payments only, not principal
- Property taxes — the full annual amount paid to the municipality
- Insurance premiums — landlord/rental property insurance
- Utilities — if you pay heat, hydro, or water on behalf of tenants
- Property management fees — if you use a management company
- Repairs and maintenance — patching, painting, fixing appliances
If you're not claiming all of these, start there. Then keep reading.
The Expenses Most Canadian Landlords Miss
1. Vehicle and Mileage Expenses
Every time you drive to your rental property — for inspections, repairs, meeting tenants, picking up supplies — those kilometres are deductible.
You can claim a proportional share of your total annual vehicle costs based on the percentage of kilometres driven for rental purposes versus total kilometres driven.
What counts toward your vehicle deduction:
- Gasoline and oil
- Car insurance
- Repairs and maintenance
- License and registration fees
- Loan interest on your vehicle (not principal)
- Capital Cost Allowance (depreciation) on the vehicle
Example: You drive 20,000 km per year total. 4,000 km relate to your rental property (trips to the property, hardware store runs, tenant meetings). That's 20% business use. If your total annual vehicle costs are $8,000, you can deduct $1,600.
What CRA requires: A mileage log. Date, destination, purpose, and kilometres for each trip. Without it, CRA will likely disallow the deduction on audit. Use a notes app, a spreadsheet, or a free mileage tracking app. If you forgot to track this year, reconstruct it now using your calendar and Google Maps history — better a reasonable estimate than nothing.
2. Home Office Expenses
If you manage your rental property yourself — handling tenant communications, bookkeeping, maintenance coordination, advertising — and you do this from a dedicated space in your home, you can deduct a proportional share of your home costs as a rental expense.
How to calculate your deduction:
- Measure the square footage of your home office
- Divide by the total square footage of your home
- Apply that percentage to eligible home costs
Eligible home costs for the deduction:
- Mortgage interest (not principal) or rent
- Property taxes on your primary residence
- Home insurance
- Utilities (heat, hydro, water)
- Internet (if not already claimed separately)
- Home maintenance and minor repairs proportional to the office
Example: Your home office is 120 sq ft in a 1,200 sq ft home — that's 10%. Your annual home costs (mortgage interest + property taxes + utilities + insurance) total $28,000. You can deduct $2,800 as a rental property expense.
The office must be used regularly and exclusively for rental administration work, not as a dual-purpose space.
3. Phone and Internet
If you use your cellphone and home internet to communicate with tenants, respond to maintenance requests, manage listings, and handle banking for the property, a reasonable portion of those bills is deductible.
There's no fixed rule on the percentage — CRA looks for "reasonable." For most landlords managing one or two properties, claiming 25–50% of your monthly phone and internet bills is defensible. Keep your monthly bills as receipts.
Annual deduction potential: At $150/month combined for phone and internet, claiming 40% yields $720/year in deductions — small individually, but it adds up across all the missed items.
4. Advertising and Tenant Acquisition Costs
Every dollar you spend finding tenants is deductible:
- Paid listings on Kijiji, Zumper, Facebook Marketplace, or rental platforms
- Professional photography for your listing
- Signage
- Credit check or tenant screening fees you pay
Keep receipts for all of these. The amounts are often small but they're 100% legitimate and 100% deductible.
5. Professional Services
Many landlords don't realize the full scope of professional fees they can deduct:
- Accounting and tax preparation fees — the portion of your annual accounting bill that relates to your rental income reporting. If your accountant charges $1,500 and roughly half the work relates to your rental, $750 is deductible.
- Legal fees — for drafting lease agreements, handling tenant disputes, eviction proceedings, or any legal matter related to the rental
- Property inspection fees — if you hire a professional inspector
- Appraisal fees — in certain circumstances related to the rental
6. Bank Charges and Interest
If you maintain a separate bank account for rental income and expenses (which is strongly recommended for bookkeeping clarity), monthly banking fees are deductible.
Additionally, any interest on loans taken out specifically to purchase or improve the rental property is deductible — not just your primary mortgage. If you took a line of credit to fund a renovation, the interest on that line is a rental expense.
7. Landscaping, Snow Removal, and Cleaning
If you pay for any of the following at the rental property, they're deductible:
- Lawn care and landscaping
- Snow plowing or snow removal
- Professional cleaning between tenants
- Pest control
These are often cash or e-transfer payments to local services. Keep records of every payment — even without a formal receipt, bank or e-transfer records are generally sufficient.
8. Condo Fees
If your rental property is a condominium, your monthly condo fees (maintenance fees) are fully deductible as a rental expense. This is one of the most consistently overlooked deductions among condo landlords.
The full annual condo fee amount goes on your T776 rental income form. On a $600/month condo, that's $7,200/year in deductions — worth over $3,000 in tax savings at a 43% marginal rate.
9. Repairs vs. Improvements — Getting This Right Saves You Money
This is the most important distinction in rental property taxation, and getting it wrong costs landlords money in both directions.
Current expenses (repairs): Fully deductible in the year they occur. These restore the property to its original working condition without adding lasting value.
Examples: fixing a leaking pipe, repainting walls, replacing a broken appliance with a similar one, patching drywall, replacing broken windows.
Capital expenses (improvements): Must be added to the adjusted cost base of the property and deducted over time through Capital Cost Allowance (CCA). These extend the life of the property or add value beyond what existed before.
Examples: adding a new bathroom, replacing all flooring throughout the unit, installing central air where there was none, building a deck, putting on a new roof.
The grey area: Replacing the entire roof after it fails — is that a repair or an improvement? CRA looks at whether you're restoring to original function (repair) or upgrading (improvement). A like-for-like roof replacement is generally treated as a current expense by many tax professionals, but this is an area worth discussing with your accountant.
Why it matters: Misclassifying a $15,000 renovation as a current expense when it should be capitalized can trigger reassessment. Misclassifying a $5,000 repair as capital means you defer a deduction you could take today.
10. Capital Cost Allowance (CCA) — Use With Caution
CCA is the depreciation you can claim on the building and eligible property assets (appliances, furnishings in furnished units, etc.). Class 1 (buildings) depreciates at 4% per year on a declining balance.
Why landlords skip it: When you eventually sell the property, CRA "recaptures" any CCA you've claimed, adding it back to your income in the year of sale. This means CCA defers tax rather than eliminating it — it's a timing benefit, not a permanent saving.
When CCA makes sense:
- You plan to hold the property indefinitely and don't anticipate selling
- You're in a high-income year and expect lower income in retirement when recapture would occur
- You have significant losses to offset and need the deduction now
When to skip CCA: If you plan to sell within 5–10 years, the recapture may hit you at an equally high or higher marginal rate, making the deferral less valuable.
Talk to a CPA before claiming CCA for the first time — the decision has long-term implications.
How to Claim Rental Expenses in Canada
All rental income and expenses are reported on Form T776 — Statement of Real Estate Rentals, filed with your personal T1 tax return.
The form asks you to list:
- Gross rental income received
- Each expense category (mortgage interest, taxes, insurance, repairs, etc.)
- Net rental income or loss
Net rental losses (when expenses exceed income) can generally be applied against your other income (employment, investment) to reduce your overall tax bill — though there are rules around properties that are consistently unprofitable, so consult a tax professional if you're regularly claiming losses.
Keeping Records CRA Will Accept
CRA can audit rental income claims up to four years after you file (or longer in cases of suspected fraud). Good recordkeeping protects you.
What to keep:
- All receipts for repairs, supplies, and services (physical or digital)
- Bank and credit card statements showing property-related payments
- Mileage log for vehicle use
- Mortgage statements showing interest paid
- Property tax bills
- Insurance renewal documents
- Lease agreements and tenant correspondence (to establish rental period)
Store these digitally — a folder in Google Drive or Dropbox organized by year works perfectly. You don't need to submit these with your return, but you must be able to produce them if CRA asks.

The Bottom Line
Rental income is taxed heavily in Canada — but the deduction framework is genuinely generous if you use it fully. The landlords who pay the least tax aren't doing anything aggressive or risky. They're just organized, they track their expenses throughout the year, and they claim everything the CRA allows.
At a 43% marginal rate in Ontario, every $5,000 in additional legitimate deductions you find is worth $2,150 in your pocket. That more than justifies spending a few hours getting your records in order — or hiring a CPA who specializes in real estate to review your return.
Recommended next step: Open a dedicated folder (physical or digital) for your rental property today. Every receipt goes in. Every km gets logged. Come tax time next year, you'll be in a completely different position.
