5. Personal Use of Dwelling Unit (Including Vacation Home)

If you have any personal use of a dwelling unit (including a vacation home) that you rent, you must divide your expenses between rental use and personal use. In general, your rental expenses will be no more than your total expenses multiplied by a fraction, the denominator of which is the total number of days the dwelling unit is used and the numerator of which is the total number of days actually rented at a fair rental price. Only your rental expenses may be deducted on Schedule E (Form 1040). Some of your personal expenses may be deductible on Schedule A (Form 1040) if you itemize your deductions.

You must also determine if the dwelling unit is considered a home. The amount of rental expenses that you can deduct may be limited if the dwelling unit is considered a home. Whether a dwelling unit is considered a home depends on how many days during the year are considered to be days of personal use. There is a special rule if you used the dwelling unit as a home and you rented it for less than 15 days during the year.

Dwelling unit. A dwelling unit includes a house, apartment, condominium, mobile home, boat, vacation home, or similar property. It also includes all structures or other property belonging to the dwelling unit. A dwelling unit has basic living accommodations, such as sleeping space, a toilet, and cooking facilities.

A dwelling unit doesn’t include property (or part of the property) used solely as a hotel, motel, inn, or similar establishment. Property is used solely as a hotel, motel, inn, or similar establishment if it is regularly available for occupancy by paying customers and isn’t used by an owner as a home during the year.

Example. You rent a room in your home that is always available for short-term occupancy by paying customers. You don’t use the room yourself and you allow only paying customers to use the room. This room is used solely as a hotel, motel, inn, or similar establishment and isn’t a dwelling unit.
