Landlord Tax Deductions Checklist: What Self-Managers Miss

Self-managing landlords tend to capture the obvious deductions — mortgage interest, property taxes, insurance — because the bank and the county send paperwork about them. The deductions that get missed are the ones nobody mails you a form for. As a CPA who self-manages rentals, here's the checklist I'd run through before filing, organized from "everyone catches these" to "most people don't."

The ones you probably have

• Mortgage interest — from Form 1098. Interest only, never principal.
• Property taxes — often paid through escrow, so pull the actual amount from your 1098 or county statement rather than guessing from your payment.
• Insurance premiums — landlord/dwelling policy, plus the rental's share of an umbrella policy.
• Repairs and maintenance — fixes that keep the property in operating condition. (Improvements are different — see the depreciation section below.)
• Utilities you pay — water, trash, gas, electric between tenants or by agreement.

The ones self-managers miss

• Mileage. Driving to the property for showings, inspections, repairs, or to the hardware store for the property is deductible at the IRS standard mileage rate (or actual costs). The catch is documentation — keep a log with dates, destinations, and purpose. A year of routine visits adds up to a real number.
• Home office. If you regularly and exclusively use part of your home to manage your rentals, a home office deduction may be available. The rules are strict — "exclusively" means the desk isn't also the family computer — so run this one past your CPA.
• Software and subscriptions. Property management software, accounting tools, listing fees, e-signature services, even the rental's share of cloud storage. Small monthly amounts that are fully deductible and routinely forgotten.
• Professional fees. Attorney fees for leases or evictions, CPA fees for the rental portion of your return, notary and filing fees.
• Loan costs and points. Points and certain closing costs on a rental mortgage are generally deducted over the life of the loan — not all at once, but not never. Refinanced? The remaining balance of old points is often deductible in the year of the refi.
• Travel for the property. An out-of-town trip whose primary purpose is the rental (inspecting, repairing, meeting contractors) can be deductible. Mixed-purpose trips get allocated — document the business purpose contemporaneously.
• Education. Books, courses, and seminars that maintain or improve your skills as a landlord (not ones that qualify you for a new trade).
• Bank and payment fees. Account fees on the rental's bank account, wire fees, payment processing costs.
• HOA dues. Fully deductible for a rental — frequently miscategorized or lost in autopay.
• Bad debt timing (cash basis). Unpaid rent isn't deductible if you never reported it as income — but the flip side is that you shouldn't be reporting rent you never received. Cash-basis landlords sometimes do both wrong.

Depreciation: the biggest deduction most landlords underuse

Depreciation lets you deduct the cost of the building (not the land) over 27.5 years for residential rentals. Allocate your purchase price between land and building — county assessments are a common starting point — and the building portion divided by 27.5 is your annual deduction. A $275,000 building portion means a $10,000 deduction every year, no cash outlay required.

Three things landlords get wrong here:

1. Skipping it. Depreciation recapture at sale is calculated on what you were allowed to deduct, whether or not you deducted it. Skipping depreciation is paying tax twice. Missed years can usually be caught up with a CPA's help (Form 3115).
2. Expensing improvements. A new roof, remodel, or full-system replacement is an improvement: it gets capitalized and depreciated, not deducted as a repair. Calling a $14,000 roof a "repair" is a classic audit flag.
3. Forgetting appliances and components. Appliances, carpets, and certain fixtures depreciate on shorter schedules than the building. If you bought a new fridge for the unit, it has its own (faster) deduction.

The meta-deduction: records that hold up

Every item above survives scrutiny only as well as its documentation. The pattern that works: a dedicated bank account per property, every transaction categorized when it clears (not in March), receipts attached to anything unusual, and a mileage log kept as you drive. The pattern that fails: one personal account, a shoebox, and a memory.

This is the part software should do for you. Keystead connects to your bank through Plaid and categorizes rental transactions into Schedule E-aligned categories automatically using QuickBooks-style rules — so the checklist above is mostly a review, not a reconstruction. For a quick estimate of your rental's taxable income this year, the free Schedule E calculator takes about two minutes. And for the line-by-line walkthrough of the form itself, see our Schedule E guide.
