IRS rental expense rules every investor needs to know

The IRS allows landlords to deduct ordinary and necessary expenses incurred in managing, maintaining, and operating a rental property. This includes mortgage interest, property taxes, insurance premiums, property management fees, repairs, advertising, and legal or professional services related to the rental.

Travel expenses related to your rental are also deductible if you drive to the property for maintenance, tenant showings, or inspections. You can deduct the actual cost of gas, tolls, and parking or use the standard mileage rate. Keep a mileage log either way — the IRS is strict about substantiation for vehicle expenses.

Home office deductions are available if you use a dedicated space in your home exclusively for managing your rental business. This can include a portion of your rent or mortgage, utilities, and internet. The simplified method allows 5 dollars per square foot up to 300 square feet.

Not everything you spend on a rental property is deductible in the year you spend it. Capital improvements must be depreciated over time, which is a critical distinction covered in the next section. Misclassifying an improvement as a repair can trigger an IRS audit flag.

Depreciation allows you to deduct a portion of the property's cost each year, even though you haven't actually spent that money. Residential rental property is depreciated over 27.5 years. If you buy a property for 275k and the land is worth 55k, you depreciate the remaining 220k over 27.5 years — that's 8,000 dollars per year in non-cash deductions.

This phantom expense reduces your taxable income without reducing your actual cash flow. In many cases, depreciation alone can make a profitable rental property show a loss on paper, which may offset other income depending on your filing status and participation level.

Cost segregation is an advanced strategy that accelerates depreciation by identifying components of the property — appliances, carpeting, landscaping, certain fixtures — that can be depreciated over 5, 7, or 15 years instead of 27.5. This front-loads your deductions and is especially powerful for higher-value properties.

When you sell a rental property, the IRS recaptures the depreciation you've taken by taxing it at up to 25 percent. This is called depreciation recapture and catches many investors off guard. A 1031 exchange can defer this tax, but you should plan for it as part of your exit strategy.

Schedule E (Supplemental Income and Loss) is the form where you report rental income and expenses. Each property gets its own column, and you can list up to three properties per form. If you have more than three, you attach additional Schedule E pages.

Line 3 is gross rents received. Lines 5 through 19 cover your deductible expenses: advertising, auto and travel, cleaning and maintenance, commissions, insurance, legal and professional fees, management fees, mortgage interest, other interest, repairs, supplies, taxes, utilities, and depreciation. Line 21 is your net rental income or loss.

If your Schedule E shows a loss, the passive activity rules determine whether you can deduct it against other income. Most taxpayers can deduct up to 25k in rental losses if their modified adjusted gross income is below 100k and they actively participate in managing the property. Above 150k, the deduction phases out entirely.

Real estate professionals — those who spend more than 750 hours per year in real estate activities and more time in real estate than any other profession — can deduct unlimited rental losses against other income. This is a powerful tax position, but it requires meticulous time tracking and documentation.

The IRS draws a hard line between repairs and improvements, and the classification directly affects your tax bill. A repair maintains the property in its current condition — fixing a leaky faucet, replacing a broken window pane, or patching drywall. Repairs are fully deductible in the year they occur.

An improvement adds value, extends the property's useful life, or adapts it to a new use — replacing the roof, installing a new HVAC system, or adding a deck. Improvements must be capitalized and depreciated, which spreads the deduction over multiple years instead of taking it all at once.

The distinction can be nuanced. Replacing a single damaged kitchen cabinet is a repair. Replacing all the cabinets as part of a kitchen renovation is an improvement. When in doubt, lean toward the improvement classification because the IRS treats aggressive repair deductions as audit triggers.

Keep detailed records for every expenditure. Save invoices, take before-and-after photos, and note whether the work was done to fix an existing problem (repair) or to enhance the property (improvement). Your CPA will need this documentation to classify expenses correctly on your return.

The IRS can audit your return up to three years after filing, or six years if they suspect you underreported income by more than 25 percent. Your records need to survive that entire window. That means keeping every receipt, bank statement, lease agreement, and tax document for at least seven years.

Digital records are acceptable and in many ways preferable. Scan or photograph paper receipts and store them in a cloud-based system organized by year and property. If a receipt fades before the audit window closes, the scan is your backup proof.

Keep a property file for each rental that includes the purchase closing statement, loan documents, insurance policies, lease agreements, move-in and move-out inspection reports, and all correspondence with tenants. This file is your single source of truth during an audit.
