The Biggest Tax Deductions for Rental Property Owners

Almost everything you spend to own and operate a rental is deductible against the rent, and depreciation adds a large deduction you never write a check for. The biggest items for most landlords are mortgage interest, property taxes, depreciation, repairs and management. The parts that trip people up are the line between a repair and an improvement, and the passive loss rules that decide whether a loss helps you this year or later.

How rental deductions work

Most individual landlords report rental income and expenses on Schedule E. An expense is deductible when it is ordinary and necessary for managing, conserving or maintaining the rental. The IRS reference for all of this is Publication 527, Residential Rental Property.

A few ground rules apply to every category below:

• The property has to be held out for rent. Expenses during a vacancy are still deductible while you are actively trying to rent it.
• Costs to acquire the property, such as title fees, recording fees and transfer taxes, are added to your basis and depreciated. They are not deducted in the year of purchase.
• Loan costs and points on a rental mortgage are spread over the life of the loan.
• Mortgage principal is never deductible. Only the interest is.
• Personal use changes the math. If you live in part of the building or use a vacation rental yourself, expenses have to be split.

Interest, property taxes and insurance

Mortgage interest. Interest on a loan used to buy or improve the rental is generally deductible in full against rental income, and in the early years it is often your largest cash expense. Your lender reports it on Form 1098. What matters is how the loan proceeds were used. If you do a cash-out refinance on a rental and spend the cash on a personal purchase, the interest on that portion is not a rental expense.

Property taxes. Deductible on Schedule E in the year paid. The cap on state and local tax deductions applies to personal itemized deductions, not to taxes paid on a rental held for investment or business. Assessments for local improvements that raise the property's value, such as new sidewalks or a sewer line, are added to basis instead. Taxes often jump after a sale in states that reassess at the purchase price, so do not assume the seller's bill will be yours.

Insurance. Landlord policy premiums, flood coverage, umbrella coverage attributable to the rentals and similar policies are deductible. If you prepay more than one year, deduct only the part that applies to each year.

Repairs vs improvements

This is the distinction with the most money riding on it. A repair keeps the property in ordinary working condition and is deducted this year. An improvement is capitalized and depreciated, usually over 27.5 years for building components. The IRS tests whether the work is a betterment, a restoration, or an adaptation to a new use. If it is any of those, it is an improvement.

Work done before the property is first placed in service as a rental is generally capitalized, even if the same work would be a repair later.

Three safe harbors worth knowing

De minimis safe harbor. If you do not have an applicable financial statement (most small landlords do not), you can elect to expense items costing $2,500 or less per invoice or per item. A $900 refrigerator or a $1,800 water heater can be deducted in full instead of depreciated. You make the election every year by attaching a statement to a timely filed return, and you need to treat those items as expenses consistently in your own books.

Safe harbor for small taxpayers. For a building with an unadjusted basis of $1 million or less, an owner with average gross receipts of $10 million or less can elect to deduct repairs, maintenance and improvements for that building if the year's total is no more than the lesser of $10,000 or 2% of the building's unadjusted basis. On a $240,000 building, 2% is $4,800, so that is the ceiling.

Routine maintenance safe harbor. Recurring work you reasonably expect to do more than once in a 10 year period to keep a building system running can be treated as a repair.

These elections are made on the return, so tell your preparer you want them considered.

Depreciation

Depreciation is the deduction that turns a rental with positive cash flow into a rental with little or no taxable income. You deduct the cost of the building, not the land, over 27.5 years for a residential rental (39 years for nonresidential property). On a $300,000 purchase with 20% land, the building basis is $240,000, and $240,000 / 27.5 = $8,727 per full year. The first year is prorated under the mid-month convention, based on the month you place the property in service. The depreciation calculator shows the full-year figure and the recapture you would owe at sale.

Two ways to speed it up:

• A cost segregation study reclassifies part of the building into 5, 7 and 15 year property. You can estimate the effect with the cost segregation calculator.
• Bonus depreciation lets you deduct that shorter life property right away. The July 2025 tax law made 100% bonus permanent for qualified property acquired after January 19, 2025. Property acquired on or before that date and placed in service in 2025 gets 40%. The bonus depreciation calculator and the 2026 bonus depreciation post cover the dates.

Depreciation comes back at sale. Gain from depreciation on the structure is unrecaptured Section 1250 gain, taxed at a maximum 25%, and depreciation on the 5 and 7 year components is recaptured at ordinary rates, with the accelerated part of 15 year land improvements generally taxed at ordinary rates too. Recapture applies to depreciation allowed or allowable, so failing to claim depreciation does not spare you the tax at sale. It only costs you the deduction. The depreciation recapture post explains the sale side, and a 1031 exchange can defer it.

Operating costs: management, fees, utilities, travel and home office

Property management. Management fees, leasing fees and tenant placement fees are deductible. If you are deciding whether to hire one, the self-managing vs property manager analysis runs the numbers.

Professional fees. Tax preparation for the rental, bookkeeping, legal fees for leases and evictions, and landlord software are deductible. Legal and inspection fees tied to buying the property go into basis.

Utilities and services. Water, sewer, trash, gas, electric, lawn care, snow removal and pest control are deductible when you pay them. HOA dues, advertising, tenant screening, licenses and rental registration fees also count.

Travel and mileage. Local trips to show the unit, collect rent, meet contractors or buy supplies are deductible. You can use actual vehicle expenses or the IRS standard mileage rate, which changes every year, so look up the rate for the tax year. Keep a log with the date, miles and purpose. Overnight travel to an out of state rental is deductible when the primary purpose of the trip is the rental, and you should be ready to show that. If the main purpose of a trip is to make improvements, the travel cost is added to the improvement and depreciated.

Home office. A home office deduction is possible if your rental activity rises to the level of a trade or business and you use the space regularly and exclusively for it. The simplified method allows $5 per square foot, up to 300 square feet. Whether one or two rentals count as a business depends on your facts, so ask your CPA before claiming it.

Worked example: one rental, one tax year

This is an example with round numbers. You bought a house for $300,000 (land $60,000, building $240,000) with a $225,000 loan at 6.5% for 30 years. It rents for $2,400 a month and was occupied all year. Depreciation is shown for a full year.

The math: $28,800 x 0.08 = $2,304. The expenses add to $25,155, and $28,800 minus $25,155 = $3,645. Then $3,645 minus $8,727 is a loss of $5,082.

Now compare that to cash. The loan payments for the year total $17,066, of which $2,515 is principal. Principal is not deductible, so your actual cash flow is $3,645 minus $2,515 = $1,130. You put $1,130 in your pocket and reported a $5,082 loss. If you can use that loss and you are in the 22% bracket, it reduces tax on your other income by $5,082 x 0.22 = $1,118.

Passive loss limits and the QBI deduction

Passive losses. Rental activity is passive by default, and passive losses can generally only offset passive income. There is a special allowance: if you actively participate (you own at least 10% and make the management decisions, even through a manager), you can deduct up to $25,000 of rental losses against wages and other income. The allowance phases out between $100,000 and $150,000 of modified adjusted gross income and is gone above that. Different limits apply if you are married filing separately.

Losses you cannot use are suspended, not lost. They carry forward and are released against future passive income or when you sell the property in a fully taxable sale. IRS Publication 925 has the details. The two common ways around the limits are real estate professional status and the short-term rental exception (an average stay of 7 days or less plus material participation). Both have strict tests.

In the example above, an owner with $90,000 of income uses the full $5,082 loss this year. An owner with $200,000 of W-2 income carries it forward.

QBI deduction. Section 199A allows a deduction of up to 20% of qualified business income, and the July 2025 tax law made it permanent. A rental only qualifies if it rises to the level of a trade or business, which depends on facts such as how many properties you have and how involved you are. The IRS offers a safe harbor that requires, among other things, 250 or more hours of rental services a year with separate books and records, and it excludes some arrangements such as triple net leases. There is also nothing to deduct in a year when the rental shows a tax loss. Treat QBI as a question for your CPA, not a given.

Common mistakes

• Not claiming depreciation. You owe recapture on depreciation you were allowed to take whether or not you took it.
• Depreciating the full purchase price, including land.
• Deducting a new roof or a full renovation as a repair.
• Depreciating a $700 appliance over five years because nobody made the de minimis election.
• Deducting the whole mortgage payment instead of only the interest.
• Expensing closing costs that belong in basis.
• No mileage log. Reconstructed estimates do not hold up well.
• Assuming a large paper loss will reduce this year's tax when your income is above the passive loss phase-out.
• Forgetting suspended losses when you sell. They should be released in the year of a fully taxable sale.

Bottom line

Track every expense by category, get the repair vs improvement call right, make the safe harbor elections, and always claim depreciation. Then check whether the passive loss rules let you use a loss now or later, because that changes how much faster write-offs are worth to you. The investor tax tools will size the big items, and the real estate tax strategy guide shows how they fit together.
