Step1
1. Interest. Interest is often a landlord's single biggest deductible expense. Common examples of interest that landlords can deduct include mortgage interest payments on loans used to acquire or improve rental property and interest on credit cards for goods or services used in a rental activity.
Step2
Depreciation. The actual cost of a house, apartment building, or other rental property is not fully deductible in the year in which you pay for it. Instead, landlords get back the cost of real estate through depreciation. This involves deducting a portion of the cost of the property over several years. Residential rental property must be depreciated over 27.5 years. However, if done properly, the depreciable life can be shorted to 15 or 5 years.
Step3
Repairs. The cost of repairs to rental property (provided the repairs are ordinary, necessary, and reasonable in amount) are fully deductible in the year in which they are incurred. Good examples of deductible repairs include repainting, fixing gutters or floors, fixing leaks, plastering, and replacing broken windows.
Step4
Local travel. Landlords are entitled to a tax deduction whenever they drive anywhere for their rental activity. For example, when you drive to your rental building to deal with a tenant complaint or go to the hardware store to purchase a part for a repair, you can deduct your travel expenses. If you drive a car, SUV, van, pickup, or panel truck for your rental activity (as most landlords do), you have two options for deducting your vehicle expenses: You can use the standard mileage rate or you can deduct your actual expenses (gasoline, upkeep, repairs).
Step5
Long Distance Travel. If you travel overnight for your rental activity, you can deduct your airfare, hotel bills, meals, and other expenses. If you plan your trip carefully, you can even mix landlord business with pleasure and still take a deduction. However, IRS auditors closely scrutinize deductions for overnight travel -- and many taxpayers get caught claiming these deductions without proper records to back them up. To stay within the law (and avoid unwanted attention from the IRS), you need to properly document your long distance travel expenses.
Step6
Home Office. Provided they meet certain minimal requirements, landlords may deduct their home office expenses from their taxable income. This deduction applies not only to space devoted to office work, but also to a workshop or any other home workspace you use for your rental business. This is true whether you own your home or apartment or are a renter.
Step7
Employees and Independent Contractors. Whenever you hire anyone to perform services for your rental activity, you can deduct their wages as a rental business expense. This is so whether the worker is an employee (for example, a resident manager) or an independent contractor (for example, a repair person).
Step8
Casualty and Theft Losses. If your rental property is damaged or destroyed from a sudden event like a fire or flood, you may be able to obtain a tax deduction for all or part of your loss. These types of losses are called "casualty" losses. You usually won't be able to deduct the entire cost of property damaged or destroyed by a casualty. How much you may deduct depends on how much of your property was destroyed and whether the loss was covered by insurance.
Step9
Insurance. You can deduct the premiums you pay for almost any insurance for your rental activity. This includes fire, theft, and flood insurance for rental property, as well as landlord liability insurance. And if you have employees, you can deduct the cost of their health and workers' compensation insurance.
Step10
Legal and Professional Services. Finally, you can deduct fees that you pay to attorneys, accountants, property management companies, real estate investment advisors, and other professionals. You can deduct these fees as operating expenses as long as the fees are paid for work related to your rental activity.
