Rental property tax deductions: what landlords can write off

Owning a rental comes with more moving parts at tax time than most owners expect, and a surprising number of landlords leave real money on the table simply because they don't know what qualifies. The tax code is genuinely generous to rental property owners — but only if you know where to look. Here's a straightforward walk-through of what you can typically deduct, the distinctions that matter, and where owners most often trip up.

The core operating expenses you can deduct

Most of what you spend keeping a rental running is deductible against your rental income in the year you pay it. That includes mortgage interest — usually the single largest deduction for a leveraged rental — along with property taxes, the rental portion of your insurance, and any utilities you pay on the tenant's behalf. It also covers the everyday costs of finding and keeping good tenants: advertising and marketing to fill a vacancy, cleaning, yard care, and pest control, and routine HOA dues and supplies. None of this is exotic — it's simply the ordinary cost of running a rental business, and the IRS treats it that way.

Property management fees are fully deductible

If you use a property manager, the fees you pay are a fully deductible ordinary business expense — the same as any other cost of operating the rental. That includes the ongoing management fee, leasing fees, and any bookkeeping or reporting services included in your agreement. It's one of the more overlooked deductions, and one more reason the real cost of professional management — see our breakdown of what management costs in the Denver metro — is often lower than the sticker number suggests. If you're still weighing whether to hire out management at all, our guide on whether a property manager is worth it covers the full trade-off. The same goes for professional, legal, and accounting fees — a CPA's bill, an attorney's advice on a lease, or the subscription for your bookkeeping software are all deductible costs of doing business.

Repairs vs. improvements: the distinction that trips people up

This is where most landlords get tangled up, and it's worth slowing down for. A repair keeps the property in the ordinary working condition it was already in — fixing a leaking faucet, patching drywall, replacing a broken window. Repairs are deductible in full in the year you pay for them. An improvement, on the other hand, adds value to the property or extends its useful life — a new roof, a remodeled kitchen, a room addition. Improvements can't be deducted all at once; instead, they're capitalized and depreciated over time. Confusing the two — deducting a new roof as if it were a repair — is one of the most common (and most easily flagged) errors on a landlord's return, so keep clear records of which category each project falls into.

Depreciation: the deduction that doesn't cost you a dime

Depreciation is the deduction that surprises new owners most, because it doesn't correspond to any cash actually leaving your pocket that year. The IRS allows you to depreciate the value of a residential rental building over 27.5 years — roughly 3.636% of the building's value each year. Land itself isn't depreciable, so only the structure's value counts toward the calculation. Spread out over nearly three decades, depreciation quietly lowers your taxable rental income year after year, which is part of why rental real estate can show a paper loss even when the property is cash-flowing just fine.

Travel, mileage, and the paper trail

If you drive to inspect the property, meet a contractor, or handle management tasks yourself, that travel and mileage is generally deductible. As with every deduction on this list, documentation is what makes it hold up — a mileage log, dated receipts, and separate accounts for rental income and expenses. Keep your rental finances out of your personal checking account. Good records aren't just good practice; they're what stands between a smooth tax filing and a stressful one if you're ever asked to substantiate a deduction. One line worth remembering, too: purely personal-use expenses aren't deductible — only the portion of a cost that's genuinely tied to the rental business qualifies.

The $25,000 active participation loss allowance

If you actively participate in managing your rental — reviewing tenant applications, approving repairs, setting rental terms — you may be able to deduct up to $25,000 of rental losses against your other income in a given year. This is a meaningful benefit for owners whose rentals run at a paper loss after depreciation and other deductions, but it isn't unlimited: the allowance phases out at higher income levels, so whether it applies to your situation depends on your full financial picture.

That's the general landscape — but every owner's situation is different, and tax law changes. This article is meant as an overview, not a substitute for professional advice, so talk to a CPA or tax professional about how these deductions apply to your specific rental before you file.
