The Payoff: 7 Tax Deductions Most Canadian Landlords Miss
Canadian landlords leave $7,000-23,000 in deductions on the table every year. Here are 7 commonly missed deductions and what each one is worth.
You’re already paying mortgage interest, property taxes, and insurance on your rental properties. The question is: are you actually deducting everything you’re allowed to?
Most Canadian landlords aren’t. Not because they’re doing anything wrong, but because nobody told them what’s deductible, and their records aren’t organized enough to claim it all.
The result? You could be overpaying the CRA by $7,000-23,000 every year.
Here are the 7 deductions small landlords most commonly miss, what they’re worth, and how to start claiming them.
This is Part 3 of a 3-part series on surviving as a small Canadian landlord. Part 1: The Squeeze covers the financial pressures hitting landlords in 2026. Part 2: The Chaos explains how disorganized records cost you thousands.
The short version: The 7 most commonly missed deductions for Canadian landlords are Capital Cost Allowance (CCA), mileage, home office, small repairs, professional fees, insurance premiums, and advertising. Combined, they total $7,700 to $23,000 per year for a landlord with 5 properties, translating to $2,310 to $6,900 in actual tax savings at a 30% marginal rate.
Why most landlords overpay
Three reasons:
-
They don’t know what’s deductible. The CRA allows dozens of expense categories on the T776, but most landlords only claim the obvious ones: mortgage interest, property tax, insurance. They miss the rest.
-
They’re afraid of the CRA. Some landlords under-claim because they think aggressive deductions will trigger an audit. In reality, the CRA expects you to claim legitimate expenses. That’s what the T776 is for. Under-claiming doesn’t protect you; it just costs you money.
-
Their records are too messy to claim everything. If you can’t find the receipt, you can’t claim the deduction. Bad record-keeping is the #1 reason landlords leave money on the table.
Let’s fix all three.
Deduction #1: Capital Cost Allowance (CCA)
What it is: Depreciation on your rental building and capital assets.
Why landlords miss it: Most have never heard of it. It’s in a separate section of the T776 (Area A) that many landlords skip entirely.
What it’s worth:
Your rental building (not the land) depreciates at 4% per year on a declining balance. On a building with a cost basis of $350,000:
- Year 1: $7,000 (half-year rule applies)
- Year 2: $13,720
- Year 3: $13,171
- 5-year total: $58,674 in deductions
That’s real money. At a 30% marginal tax rate, CCA on the building alone saves you $3,500-4,000 per year in taxes.
Appliances (Class 8) depreciate at 20%. A $3,000 fridge/stove combo generates $600 in CCA the first full year.
The catch: CCA can’t create or increase a rental loss. And when you sell, you may face recapture (the CCA gets added back to income). But for most landlords holding long-term, the time value of money makes CCA very worthwhile.
For the full breakdown, see our Capital Cost Allowance guide.
Deduction #2: Mileage to your properties
What it is: The cost of driving to your rental properties for management, inspection, repair, or maintenance.
Why landlords miss it: They don’t keep a mileage log. No log = no deduction.
What it’s worth:
The CRA mileage rate is $0.73/km for the first 5,000 km and $0.67/km after that (2026 rates).
If you visit your properties twice a month and each round trip is 20 km:
- 24 trips x 20 km = 480 km/year per property
- 5 properties = 2,400 km/year
- 2,400 km x $0.73 = $1,752 deduction
If you self-manage and do your own maintenance, the mileage adds up fast. Some landlords drive 5,000+ km per year for their rental business.
How to claim it: Log every trip with the date, destination, distance, and purpose. The CRA requires a contemporaneous log, meaning you should record the trip when it happens, not reconstruct it at tax time.
Deduction #3: Home office expenses
What it is: A portion of your home expenses, if you use a dedicated space to manage your rental properties.
Why landlords miss it: They think it’s only for self-employed people or home businesses. It’s not. If you regularly use a room or area of your home for rental management (bookkeeping, tenant communication, property research), you can claim a proportional deduction.
What it’s worth:
Calculate the percentage of your home used for rental management. If your home is 1,500 sq ft and your office is 150 sq ft, that’s 10%.
Deductible home expenses (at 10%):
- Rent or mortgage interest: $2,000/month x 10% = $200/month = $2,400/year
- Utilities: $300/month x 10% = $360/year
- Internet: $80/month x 10% = $96/year
- Home insurance: $150/month x 10% = $180/year
- Total: $3,036/year
This deduction is often overlooked by landlords who manage their own properties from home.
The CRA expects the space to be used regularly for rental-management tasks, not just occasionally. Keep notes on the hours you spend in that space on bookkeeping, tenant communication, and property research, in case you need to justify the claim later.
Deduction #4: Repairs you forgot to claim
What it is: Any repair that restores your property to its original condition. Unlike capital improvements, repairs are 100% deductible in the year incurred.
Why landlords miss it: Small repairs feel too insignificant to track. But they add up.
What it’s worth:
Common repairs landlords forget to claim:
- Plumber call to fix a leak: $150-300
- Replacing door locks between tenants: $50-150
- Patching drywall: $100-200
- Fixing a leaky faucet: $75-150
- Replacing a broken window: $200-400
- Furnace service/tune-up: $100-200
- Electrical outlet repair: $100-250
- Pest control treatment: $200-400
Over a year across multiple properties, forgotten repairs easily total $500-2,000 in missed deductions.
The key rule: Repairs are deductible. Capital improvements are not (they go to CCA). A new furnace is a capital improvement. Fixing the old furnace is a repair. When in doubt, the CRA’s test is: did it restore the property to its original condition (repair) or make it better than before (capital improvement)?
Deduction #5: Professional fees
What it is: Fees you pay to professionals for services related to your rental business.
Why landlords miss it: They don’t connect their accountant bill to their rental properties.
What it’s worth:
Deductible professional fees:
- Accountant fees for preparing your T776: $300-800
- Legal fees for lease review or tenant disputes: $200-1,000
- Property management fees: varies (often 8-10% of rent)
- Fees paid to a bookkeeper: $100-500/year
- Total: $300-2,300/year
If you pay an accountant $600 to prepare your rental tax return, that $600 is itself a deduction on next year’s T776 (line 8860). Many landlords don’t realize this.
Deduction #6: Insurance premiums
What it is: Premiums you pay for insurance coverage on your rental property.
Why landlords miss it: They claim the basic property insurance but forget about other policies.
What it’s worth:
Deductible insurance premiums:
- Landlord property insurance: $1,200-3,000/year
- Landlord liability insurance: $300-800/year
- Mortgage default insurance premiums (CMHC): deductible over the term of the mortgage
- Total: $1,500-3,800/year
Most landlords claim their basic property insurance but forget about liability insurance and CMHC premiums. Check your mortgage agreement; if you paid a CMHC premium when you purchased, a portion is deductible each year over the term of the mortgage.
Deduction #7: Advertising for tenants
What it is: Costs you incur to advertise your rental vacancy and find tenants.
Why landlords miss it: The amounts seem too small to bother with. But they’re fully deductible under T776 line 8521.
What it’s worth:
Deductible advertising expenses:
- Rental listing fees (Kijiji, Facebook Marketplace premium): $20-100
- “For Rent” signs: $10-30
- Professional photography for listings: $100-300
- Online listing platform subscriptions: $50-200/year
- Tenant screening service fees: $25-50 per applicant
- Total: $100-700/year
Not huge individually, but if you have multiple properties with regular turnover, advertising costs add up. And every dollar is deductible.
How much are you leaving on the table?
Let’s add it all up for a landlord with 5 properties:
| Deduction | Low Estimate | High Estimate |
|---|---|---|
| CCA (building + appliances) | $5,000 | $14,000 |
| Mileage | $500 | $2,000 |
| Home office | $1,000 | $3,000 |
| Forgotten repairs | $500 | $2,000 |
| Professional fees | $300 | $800 |
| Insurance (missed policies) | $300 | $800 |
| Advertising | $100 | $400 |
| Total missed deductions | $7,700 | $23,000 |
At a 30% marginal tax rate, that’s $2,310 to $6,900 in extra tax you’re paying every year that you don’t have to.
Over 5 years, that’s $11,550 to $34,500. That’s a down payment on another property.
How to start claiming everything
The fix isn’t complicated. It’s three things:
-
Track every expense when it happens. Not at tax time. When it happens. A photo of the receipt, a quick note of what it was for, which property it relates to. Five minutes now saves five hours in April.
-
Categorize to T776 lines. Every expense maps to a specific line on the T776. If you don’t know which line, learn the main ones (repairs = 8960, insurance = 8690, property tax = 9180, interest = 8710) or use a tool that categorizes for you.
-
Claim CCA. Talk to your accountant about starting CCA claims on your building and appliances. It’s the single biggest deduction most landlords miss.
Stop leaving money on the CRA’s table
RentBase categorizes every expense to the correct T776 line automatically. Log an expense, and it’s mapped to the right deduction. Upload a receipt, and AI extracts the details for you. Log a trip to your property, and mileage is calculated at the current CRA rate.
CCA tracking calculates your building and appliance depreciation automatically with the half-year rule, rental loss restriction, and year-over-year UCC carry-forward built in.
Every dollar you track is a dollar you can deduct. Every dollar you miss is a dollar you’re giving to the CRA for free.
Start free and see how much you’ve been missing.
