Rental Income Tax in Canada: Every Deduction Landlords Can (and Can't) Claim

By Jordan Ellis · Published August 22, 2026

Quick Answer

Rental income in Canada is taxed as regular income at your marginal rate, but only on the net: deduct mortgage interest (never principal), property taxes, insurance, condo fees, repairs and maintenance, property management, advertising, utilities you pay, and accounting fees. The two audit traps: capital improvements (a renovation that adds lasting value) must be depreciated over years, not deducted at once — and claiming CCA (capital cost allowance, 4% declining on the building) reduces tax now but is fully recaptured as income when you sell if the property held its value, which is why many landlords skip it. Report everything on Form T776.

A rental property is a small business wearing a house costume — and CRA taxes it like one. The good news: nearly every dollar the property costs you is deductible. The bad news: two specific lines on the T776 trigger most audits. Here’s the map — then run your net position through the income tax calculator.

What’s deductible (the honest list)

Mortgage interest — never the principal portion; your annual statement splits them
Property taxes and insurance
Condo fees (for the rental unit)
Repairs & maintenance — the current-expense line
Property management and leasing fees, tenant advertising
Utilities you pay, accounting/legal for the rental, office supplies
Vehicle costs for rent collection/maintenance trips (limited for single-property landlords)
Prepaid expenses pro-rated to the year they belong to

On $30,000 of rent with $18,000 of expenses, you pay tax on $12,000 — at a 40% marginal rate, $4,800. The mortgage calculator shows exactly how much of each payment is interest as the amortization runs.

Trap #1: current expense vs capital improvement

The line CRA audits hardest. Repair = restore to original condition → deduct now. Improvement = better, longer-lasting, new use → capitalize, depreciate over years.

Repaint after a tenant: deduct now
Renovate the kitchen: capitalize
Patch the roof: deduct; replace the roof: capitalize

Same $20,000, completely different tax years. When in doubt, ask: did I fix it, or did I upgrade it?

Trap #2: CCA and the recapture boomerang

Capital Cost Allowance lets you depreciate the building (4% declining, class 1 — never the land) against rental income. It feels like free money until the sale: every dollar of CCA ever claimed is recaptured as full-rate income if the building held its value. In any appreciating market, that’s nearly guaranteed — so CCA usually just moves tax from now to the sale year, often at a worse bracket, and it can never create or increase a rental loss on a building anyway. Many long-term landlords skip it deliberately.

The exit math

Sell a $400,000 rental for $700,000:

Capital gain $300,000 → 50% taxable → $150,000 income (capital gains mechanics)
CCA recapture on top, if you claimed it
Any years it was your principal residence stay exempt, pro-rated

At top brackets the total bill can approach $75,000 — which is why sale years deserve tax planning: timing the sale to a low-income year, or spreading proceeds via a vendor take-back.

Keep the records like you mean it

CRA can reassess rentals years back; the file needs every receipt, the mortgage interest statement, and a log separating repair from reno. Software or a spreadsheet — pick one and be religious. And remember the asset side: the property is presumably your largest net worth line and its financing deserves the same rigor as the tax side — the investment property mortgage guide covers that half.

Frequently Asked Questions

How is rental income taxed in Canada?

Net rental income — rent minus deductible expenses — is added to your other income and taxed at your marginal rate. At a 40% marginal rate, $10,000 of net rental profit costs $4,000 in tax. Losses (expenses exceeding rent) can be deducted against your other income, but only when they are genuine — years of manufactured losses invite CRA scrutiny.

What expenses can landlords deduct?

Mortgage interest (not principal), property tax, insurance, condo fees, repairs and maintenance, property management fees, advertising for tenants, utilities you cover, legal and accounting fees related to the rental, office expenses, and motor vehicle costs for collecting rent or managing the property (with limits for a single property). Each must be reasonable, documented, and tied to earning rental income.

What is the difference between a repair and a capital improvement?

A repair restores something to its original condition — deductible in full this year. An improvement makes it better, longer-lasting, or adapted to a new use — capitalized and depreciated over years. Repainting: repair. Kitchen renovation: capital. Replacing a few boards on the deck: repair; rebuilding the whole deck: capital. This line is the number-one rental-audit issue.

Should I claim CCA on my rental property?

Usually not, unless you need losses now. CCA (typically 4% declining balance on the building) shelters rental income today, but when you sell, all CCA claimed is recaptured — added back as income — if the building sold for more than its depreciated cost. In appreciating markets that recapture is nearly certain, so CCA often just defers tax to a year when your income may be higher. Model both paths before claiming.

Do I pay capital gains tax when I sell a rental property?

Yes — the principal residence exemption does not cover rental years. On sale, 50% of the capital gain is taxable income, plus any CCA recapture in full. A property bought at $400,000 and sold at $700,000 creates a $300,000 gain: $150,000 taxable, costing roughly $45,000-$75,000 at top brackets. Years it was your principal residence remain exempt — the math pro-rates.
