Rental Property Deductions: Every Expense Landlords Can Write Off

Rental property income is reported on Schedule E (Supplemental Income and Loss). The net income (or loss) flows to the tax return after deducting all ordinary and necessary expenses of owning and operating the rental. The goal is to report every legitimate deduction, which often produces a paper loss even when the property generates positive cash flow (because depreciation is a non-cash deduction).

What’s the difference between a repair and an improvement?

This distinction is the most common audit issue for rental property owners. For current guidance, see IRS Publication 535 (Business Expenses). Repairs are currently deductible. Improvements must be capitalized and depreciated over their useful life (27.5 years for residential property improvements, or shorter lives for specific components).

The IRS uses the “betterment, adaptation, or restoration” test from Treas. Reg. 1.263(a)-3:

• Betterment: Makes the property better than it was before (not just returning it to its original state). Example: upgrading a kitchen with granite countertops and stainless appliances when the original had laminate and basic appliances.
• Adaptation: Changes the property to a new or different use. Example: converting a garage into a rental apartment.
• Restoration: Replaces a major component or structural part of the property. Example: replacing the entire roof (vs. patching a section, which is a repair).

How does depreciation create a paper loss?

Depreciation is the most valuable rental property deduction because it represents a non-cash expense. The landlord doesn’t write a check for depreciation, but it reduces taxable rental income (and can create a tax loss).

A rental property generating $2,000/month in rent ($24,000/year) with $14,000 in cash expenses (mortgage interest, taxes, insurance, repairs, management) produces $10,000 in positive cash flow. But if the building (excluding land) is worth $275,000, the annual depreciation deduction is $10,000. That wipes out the $10,000 cash flow, resulting in zero taxable income, even though the landlord pocketed $10,000 in cash.

With a cost segregation study that accelerates depreciation on specific components (appliances, flooring, fixtures), the depreciation deduction can exceed the cash flow, creating a paper loss that offsets other income (subject to passive activity rules).

What is the difference between an above-the-line and below-the-line deduction?

Above-the-line deductions (adjustments to income on Schedule 1) reduce your adjusted gross income (AGI), which lowers the threshold for AGI-based limitations on other deductions and credits. Common above-the-line deductions include self-employed health insurance, half of self-employment tax, student loan interest, and IRA contributions. Below-the-line deductions reduce taxable income after AGI is calculated, either through itemizing (Schedule A) or the standard deduction. Business deductions on Schedule C are neither above nor below the line; they reduce gross income to arrive at net profit, which then flows into AGI. For self-employed taxpayers, maximizing above-the-line deductions is particularly valuable because they reduce both income tax and the AGI thresholds that gate other tax benefits.

Can a landlord deduct a rental loss against a paycheck?

Up to $25,000 a year, if you actively participate in the rental, own at least 10% of it, and your modified AGI is $100,000 or less. Active participation is a low bar: approving tenants, setting rental terms, and approving expenses all count. Above $100,000 of modified AGI, the allowance drops 50 cents for every dollar over and is gone at $150,000.

Modified AGI is your AGI figured without taxable Social Security, IRA deductions, the student loan interest deduction, or the passive loss itself. Married filing separately? You get nothing if you lived with your spouse at any point in the year, and $12,500 if you lived apart all year. None of these dollar amounts are indexed, so they’re the same for 2025 and 2026.

Whatever the allowance doesn’t absorb carries forward to next year. Keep that in mind before a cost segregation study: a bigger paper loss only helps now if you have room under the allowance, passive income to absorb it, or real estate professional status plus material participation in the rental.
