Landlord Tax Guide: Mortgage Interest, Depreciation, Property Taxes & More

Rental income is taxable, but smart landlords can meaningfully lower their tax bill by claiming major deductions such as mortgage interest, property taxes, depreciation, ordinary repairs, and a range of operating expenses. Understanding what counts as rental income, how to differentiate repairs from improvements, and which costs are deductible versus capitalized helps you report accurately and avoid red flags.

Summary

😊 Rental income basics

All money and certain benefits you receive from a rental—monthly rent, fees for breaking a lease, non-refunded portions of a security deposit kept to cover damage, and other payments related to the tenancy—are generally included in your gross income and taxed at your ordinary income tax rates. Rental income is reported on your tax return, and most small landlords use Schedule E to list income and expenses for each property. Remember that “income” is broader than just the check you get each month; charges you assess for rule violations or damages can also be taxable, while truly refundable security deposits that you return in full typically are not counted as income. Tracking these inflows carefully ensures you don’t underreport—and that you line up the right deductions against that income.

Takeaways:

• Rental income includes more than base rent (e.g., lease-break fees, certain non-refundable deposits).
• Report rental income and expenses on Schedule E for most residential rentals.
• Your marginal tax bracket determines how that net rental income is taxed.

Key Terms

• Gross income: Total taxable receipts from the rental, including certain fees and retained deposits.
• Schedule E: IRS form used by many landlords to report rental income and deductible expenses.
• Marginal tax rate: The percentage at which your last dollar of income is taxed.

🧾 Mortgage interest deduction

Interest you pay on a rental property mortgage is usually deductible because the property is an income-producing business asset. Your lender should provide Form 1098 each January or early February showing interest paid during the year—use that figure when preparing your return. You’ll typically claim the deduction on Schedule E for the specific property. Since this is one of the largest ongoing costs for many landlords, capturing the full interest amount can significantly reduce taxable rental income. Keep statements and your 1098 for your records, and separate interest from principal—only interest is deductible as a current expense.

Takeaways:

• Mortgage interest on rental property is a business expense and commonly deductible on Schedule E.
• Use Form 1098 to verify the annual interest paid; principal isn’t deductible.

Key Terms

• Form 1098: Annual statement from your lender showing mortgage interest paid.
• Business expense: An ordinary and necessary cost of operating your rental activity.

🧱 Depreciation deduction

Unlike a personal residence, a rental is treated as a business asset that wears out over time, so you can deduct its cost gradually through depreciation. For residential real estate, the IRS generally assigns a 27.5-year recovery period, meaning you write off the building’s value (not land) over 27.5 years using an approved method. Depreciation can create a sizable annual deduction that often turns positive cash flow into little or no taxable income. The rules can get technical—co-ops and condos may have special considerations; the basis you depreciate excludes land; and improvements increase basis and therefore future depreciation—so many landlords lean on a tax pro to set up the schedules correctly. You can begin depreciating when the property is ready and available for rent, even if it isn’t occupied yet.

Takeaways:

• Residential rental buildings are typically depreciated over 27.5 years; land is not depreciable.
• Start depreciation when the property is placed in service (ready to rent).
• Capital improvements increase your basis and future depreciation.

Key Terms

• Depreciation: A yearly deduction that spreads the building’s cost over its useful life.
• Basis: Generally your cost in the property (plus certain costs and improvements, excluding land) used to compute depreciation.
• Placed in service: The date the property is ready and available for rent.

🏡 Property tax deduction

Property taxes are typically deductible for rental properties as operating expenses. While personal tax rules cap the itemized deduction for state and local taxes at $10,000 ($5,000 if married filing separately), that SALT limit does not apply to business activities such as rentals. That means landlords can usually deduct the full amount of property taxes they pay on their rentals on Schedule E. Because this is easy to overlook, confirm your annual payments to the county or municipality and include any amounts paid through escrow with your lender.

Takeaways:

• Property taxes on rentals are generally fully deductible for the business, not subject to the personal SALT cap.
• Gather tax bills and escrow statements to capture the full deduction.

Key Terms

• SALT cap: The $10,000 ($5,000 MFS) limit on itemized state and local tax deductions for individuals—doesn’t apply to rental business expenses.
• Escrow: Funds your lender collects to pay property taxes and insurance on your behalf.

🔧 Repairs vs. improvements (and why it matters)

Ordinary repairs—fixing a leaky faucet, replacing broken light fixtures, patching drywall, servicing a garbage disposal—are generally deductible in the year you pay them because they keep the property in efficient operating condition. By contrast, improvements that add value, prolong useful life, or adapt the property to a new use (for example, adding a bedroom, installing a new roof, upgrading HVAC, putting in storm windows, new water heater, major landscaping, flooring, insulation, or a security system) are typically capitalized. Capitalized costs aren’t deducted all at once; instead, they increase your basis and are recovered over time, often via depreciation. Classifying these correctly is critical: deducting large capital projects as “repairs” can invite IRS scrutiny. When in doubt, document the purpose of the work, keep invoices, and consider guidance in IRS materials for examples of costs that must be capitalized.

Takeaways:

• Repairs are usually currently deductible; improvements are capitalized and recovered over time.
• Examples of capitalized items often include additions, new roofs, HVAC systems, water heaters, security systems, major landscaping, flooring, and insulation.
• Misclassifying big projects as repairs can raise audit flags.

Key Terms

• Repair: An expenditure that keeps the property in ordinary efficient operating condition.
• Improvement: A cost that betters, restores, or adapts the property—generally capitalized and depreciated.
• Capitalization: Treating a cost as part of the asset’s basis rather than deducting it immediately.

🧰 Other deductible expenses

Beyond the “big three” (interest, depreciation, property taxes) and routine repairs, landlords often deduct a variety of operating costs that keep the rental running. Common examples include advertising the vacancy, landlord insurance premiums, utilities you pay for the unit, property management fees, postage and office supplies tied to the rental, and local business license fees. Transportation for rental activities—such as driving to the property to show it, perform maintenance, or pick up supplies—may also be deductible, using either the standard mileage rate (if allowed) or actual expenses. Keep contemporaneous mileage logs and receipts. Note that commuting between your personal residence and the rental is typically not deductible unless your home qualifies as your principal place of business for the rental activity under applicable rules.

Takeaways:

• Deductible operating costs can include advertising, insurance, utilities you pay, supplies, and mileage for rental-related trips.
• Maintain good records—logs, receipts, and invoices—to substantiate deductions.

Key Terms

• Operating expenses: Ordinary and necessary costs to manage, conserve, and maintain a rental.
• Standard mileage rate: A per-mile deduction method for business vehicle use when permitted.
• Principal place of business: A test to determine whether home-based administrative work qualifies for certain deductions.

🚫 Common nondeductible items to watch

Some costs feel “loss-like” but aren’t deductible against rental income. Two common examples: uncollected rent (depending on your accounting method, many small landlords use cash basis and never recognized it as income to begin with) and lost income from vacancies. Personal commuting to and from the property is also generally nondeductible. Understanding these boundaries helps you focus on deductions you can legitimately claim while avoiding adjustments later.

Takeaways:

• Uncollected rent and vacancy losses typically aren’t deductible.
• Commuting mileage is usually nondeductible; rental-purpose trips may qualify.

Key Terms

• Cash method: Accounting that recognizes income when received and expenses when paid.
• Vacancy loss: The opportunity cost of an unoccupied unit—generally not deductible.

Conclusion

Landlords can substantially reduce taxable rental income by correctly capturing mortgage interest, property taxes, depreciation, repair costs, and everyday operating expenses—while capitalizing true improvements and avoiding nondeductible pitfalls. Careful record-keeping and a clear repair-versus-improvement framework go a long way toward clean, confident filing.
