Landlords may reduce taxable rental income by claiming ordinary and necessary expenses directly tied to property rental, but specific rules determine what counts and when costs must be capitalized. Authoritative guidance appears in Publication 527 by the Internal Revenue Service, which explains allowable deductions, recordkeeping expectations, and limits.
Common deductible expenses
Typical deductible items include mortgage interest, property taxes, insurance premiums, advertising, professional fees for accountants and attorneys, and management or leasing costs. Costs for routine upkeep such as painting, fixing a leaking pipe, or replacing a broken window are generally deductible as repairs, while larger expenditures that add value or prolong useful life are capital improvements and must be recovered through depreciation rather than immediate deduction. Utilities paid by the owner, tenant screening costs, and ordinary supplies used to operate the rental are also commonly deductible. Guidance on classification of repairs versus improvements appears in Publication 527 and Publication 946 by the Internal Revenue Service.
Limits, depreciation, and broader consequences
Depreciation allows owners to recover the cost of the building (but not the land) over time; for residential rental property the recovery period is described in Publication 946 by the Internal Revenue Service and is commonly treated over a multi-decade schedule. Special rules can limit loss deductions: passive activity loss rules restrict deducting rental losses against nonrental income unless the taxpayer qualifies as an active participant or real estate professional, as explained in Publication 925 by the Internal Revenue Service. When a property is sold, depreciation previously claimed can lead to depreciation recapture, which affects after-tax proceeds.
These tax rules have practical and social consequences. Favorable deductions for maintenance can encourage landlords to keep properties safe and habitable, while complex capitalization rules may influence decisions about renovations versus ongoing repairs. Smaller landlords without professional tax help face higher audit risk if records are incomplete, so meticulous receipts and consistent accounting methods are important. Energy-efficiency upgrades may offer different tax treatments, including credits or accelerated cost recovery, creating environmental and economic incentives that vary with local policy. For reliable application to specific situations, consult the cited Internal Revenue Service publications and consider professional tax advice.
