Ontario Landlord Tax Deductions: The Complete T776 Guide

The Form That Saves You Thousands

If you own a rental property in Ontario and you're not filing Form T776(Statement of Real Estate Rentals) with your tax return, you're overpaying CRA. Full stop.

T776 is where you report your rental income and deduct every eligible expense against it. The result? Your taxable rental income drops. Sometimes to zero. Sometimes below zero, which means the loss offsets your other income too.

Every individual who earns rental income in Canada needs to file this form. It doesn't matter if you own one basement unit or twelve condos. One property, one T776. Multiple properties can go on the same form if you own them in the same capacity.

T776 is filed as part of your annual tax return. Same deadline: April 30 for most people, June 15 if you're self-employed (but any balance owing is still due April 30).

What You Can Deduct

Here's the full list of expenses CRA lets you deduct against rental income. Every dollar here reduces the tax you owe.

Mortgage Interest

The interest portion of your mortgage payment. Not the principal. If your monthly mortgage payment is $2,000 and $1,200is interest, you're deducting $14,400 per year. Your lender sends you an annual mortgage statement that breaks this down. Use it.

Property Tax

The full amount of property tax on a dedicated rental property. If you live in the property too (mixed-use), only the rental portion is deductible. More on that below.

Insurance Premiums

Landlord insurance, liability coverage, anything that protects the rental property. Only the portion for the current tax year counts. Paid a 2-year policy upfront? You deduct half this year, half next year. CRA doesn't let you front-load multi-year premiums.

Repairs and Maintenance

Fixing a broken furnace. Patching drywall. Replacing a leaky faucet. Unclogging a drain. Repainting walls between tenants. These are current expenses because they restore the property to its original condition without improving it.

This is one of the biggest categories and one of the most audited. Keep every receipt.

Utilities

If your lease makes you responsible for utilities, you deduct them: hydro, gas, water, internet. If the tenant pays utilities directly, you can't claim them (obviously).

Advertising

The cost of listing the unit. Kijiji ads, Facebook Marketplace boosts, Rentals.ca listings, photos, virtual tours. If you paid to find a tenant, it's deductible.

Legal and Accounting Fees

Paralegal fees for LTB hearings. Accountant fees for preparing your tax return. Lawyer fees for drafting or reviewing a lease. These are all deductible as professional fees.

Travel Expenses

Driving to the property for repairs, inspections, showing the unit to prospective tenants. Track your mileage. CRA's rate for 2026 is $0.72/km for the first 5,000 km and $0.66/km after that. A 30 km round trip to fix a leaky tap? That's $21.60 you can deduct.

Keep a mileage log: date, destination, purpose, kilometres. No log, no deduction.

Office Expenses

If you manage your rental properties from a home office, you can deduct a portion of your home expenses (internet, phone, office supplies) based on the percentage of your home used for property management.

Condo Fees

If your rental unit is a condo, monthly maintenance fees are fully deductible. This often adds up to $3,000 to $6,000+ per year depending on the building.

Landscaping and Property Care

Lawn care, snow removal, tree trimming, gutter cleaning. If you're paying someone to maintain the property grounds, deduct it.

The Big Ones

Three deductions do the heavy lifting on most landlord tax returns. If you're only going to track three things carefully, make it these.

Combined, these three categories alone can easily total $20,000+in deductions. That's $20,000 of rental income that CRA won't tax.

Repairs vs. Improvements: The Line That Trips Up Everyone

This distinction is where audits start. CRA draws a hard line between a repair (deductible this year) and a capital improvement (depreciated over many years via CCA).

The test is simple. Did the work restore the property to its previous condition? Or did it improve the property beyond what it was before?

Grey area? A lot of expenses fall in between. Replacing a furnace with the exact same model could go either way. Talk to your accountant. But the principle is clear: fixing something broken is a repair. Making something better is an improvement.

What You Cannot Deduct

Landlords try to deduct these every year. CRA denies them every year.

Capital Cost Allowance (CCA): Handle With Care

CCA is how you deduct the cost of capital improvements over time. Residential rental buildings fall under Class 1, which allows a 4% deduction per year on the declining balance.

Here's the catch. CCA is optional. You don't have to claim it. And many experienced accountants tell their landlord clients to skip it entirely.

Why? Because every dollar of CCA you claim reduces your adjusted cost base. When you eventually sell the property, your capital gain is calculated as the selling price minus your adjusted cost base. Lower cost base means a bigger capital gain. Bigger capital gain means more tax on the sale.

CCA doesn't eliminate the tax. It defers it. You get a small benefit now (4% per year) and pay a larger bill later (on the entire recaptured amount when you sell).

When does CCA make sense? If your rental income is high right now and you need to reduce your current tax burden. If you don't plan to sell for decades. If you're in a high tax bracket today and expect to be in a lower one later. Otherwise, most landlords are better off leaving CCA alone.

Mixed-Use Properties

You live upstairs and rent out the basement. You own a duplex and live in one unit. These are mixed-use properties, and you can only deduct the rental portion of shared expenses.

The simplest method is square footage. Measure the total livable area of the property. Measure the rental portion. Divide.

Your house is 2,000 sq ft. The basement suite is 800 sq ft. That's 40%. So 40% of your property tax, mortgage interest, insurance, utilities, and maintenance goes on the T776. The other 60% is personal and stays off your tax return.

Be consistent. Use the same percentage every year unless you change the rental area. CRA looks for sudden jumps in your rental percentage as a red flag.

The Records CRA Wants

No receipt? No deduction. CRA doesn't take your word for it.

Keep everything for 6 years from the end of the tax year. If you file your 2026 return in April 2027, keep those records until at least the end of 2032.

Digital copies are fine. CRA accepts scans and photos of receipts. But the original information must be legible: date, vendor, amount, description of what was purchased.

A shoebox full of faded receipts from three years ago won't save you in an audit. Scan them as you go. Store them in folders by year. Your future self will thank you.

Rental Losses Can Work in Your Favour

Here's something many Ontario landlords don't realize. If your rental expenses exceed your rental income, the loss reduces your other income. Your employment income. Your business income. All of it.

Say you earned $90,000 from your job and had a $5,000 rental loss. Your taxable income drops to $85,000. That's real money back in your pocket.

This is a major advantage in Canada compared to the US, where passive rental losses are heavily restricted. Here, as long as the expenses are legitimate and you have a reasonable expectation of profit, CRA allows the loss.

One caveat: if you claim CCA and it creates or increases your rental loss, CRA will deny the excess CCA. CCA can bring your rental income to zero, but it can't push it into a loss. Only real out-of-pocket expenses can create a deductible rental loss.
