Landlord Tax Deductions: The Complete Checklist for 2026

Why most landlords miss deductions

The average small landlord misses $3,800 in tax deductions every year. Not because they're careless — but because the system for capturing deductions throughout the year simply doesn't exist for most people.

Here's what typically happens: you fix a leaky faucet in March, pay the plumber in cash, and mentally note that it was deductible. By April of the following year, you can't find the receipt, you don't remember the exact amount, and you're not sure if it was this property or the other one.

Multiply that across a year of repairs, insurance renewals, property management software, mileage to the property, and professional fees — and the missed deductions add up fast. The landlords who maximize their deductions aren't doing anything complicated. They have a system that captures expenses automatically throughout the year.

Every deductible expense category

As a landlord, you can deduct any ordinary and necessary expense for managing, conserving, or maintaining your rental property. Here's the complete list:

What Schedule E is and how to use it

In the United States, rental income and expenses are reported on Schedule E (Supplemental Income and Loss), which is filed with your Form 1040. Each rental property gets its own column on Schedule E.

Schedule E asks you to list your total rental income, then subtract each category of expense: advertising, auto and travel, cleaning and maintenance, commissions, insurance, legal and professional fees, management fees, mortgage interest, repairs, supplies, taxes, utilities, depreciation, and other expenses.

The result — income minus expenses — is your net rental income or loss, which flows to your main tax return. If you have a net loss, it may offset other income depending on your situation and passive activity rules.

In Canada, rental income and expenses are reported on Form T776 (Statement of Real Estate Rentals), which works similarly. The same categories apply.

The difference between repairs and improvements

This is one of the most common mistakes landlords make — and it can result in either missed deductions or errors that trigger an audit.

Repairs (fully deductible in the current year)

A repair restores something to its original condition without adding value or significantly extending its useful life. Examples: fixing a broken window, repairing a leaking roof, replacing a broken lock, patching drywall, repainting a unit.

Improvements (must be depreciated over multiple years)

An improvement adds value, adapts the property to a new use, or substantially extends its useful life. Examples: replacing all windows with triple-pane, adding a deck, renovating a kitchen, installing central air conditioning.

The practical test: if it makes the property meaningfully better than it was, it's an improvement. If it just brings it back to what it was, it's a repair. When in doubt, ask your accountant.

How to track deductions automatically all year

The landlords who capture all their deductions don't do it by being more organised — they do it by building a system that captures expenses as they happen, rather than trying to reconstruct them in April.

The most effective approach combines two things: a bank connection that imports expenses automatically, and a habit of logging non-bank expenses (cash receipts, mileage) in the moment.

RentDesk connects to your bank via Plaid and imports every transaction automatically. When you pay an insurance premium, it lands in RentDesk. When you hire a plumber, that transaction is imported and you can tag it as a maintenance expense with one tap. Every tagged expense goes directly into your Schedule E summary, ready to export at any time.

The result: when April arrives, you don't spend a week reconstructing records. You spend an hour reviewing what's already there.
