If you have any personal use of a vacation home or other dwelling unit that you rent out, you must divide your expenses between the rental use and the personal use. See Figuring Days of Personal Use and How To Divide Expenses, later.

If your expenses for rental use are more than your rental income, you may not be able to deduct all of the rental expenses. See How To Figure Rental Income and Deductions, later.

Exception for minimal rental use. If you use the dwelling unit as a home and you rent it for fewer than 15 days during the year, do not include any of the rent in your income and do not deduct any of the rental expenses. See Dwelling Unit Used as Home, later.

Dwelling unit. The rules in this section apply to vacation homes and other dwelling units. A dwelling unit includes a house, apartment, condominium, mobile home, boat, or similar property. A dwelling unit has basic living accommodations, such as sleeping space, a toilet, and cooking facilities. A dwelling unit does not include 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 is not used by an owner as a home during the year.

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

Dwelling Unit Used as Home

The tax treatment of rental income and expenses for a dwelling unit that you also use for personal purposes depends on whether you use it as a home. (See How To Figure Rental Income and Deductions, later.)

You use a dwelling unit as a home during the tax year if you use it for personal purposes more than the greater of:

1. 14 days, or
2. 10% of the total days it is rented to others at a fair rental price.

See Figuring Days of Personal Use, later.

If a dwelling unit is used for personal purposes on a day it is rented at a fair rental price, do not count that day as a day of rental in applying (2) above. Instead, count it as a day of personal use in applying both (1) and (2) above. This rule does not apply when dividing expenses between rental and personal use.

Fair rental price. A fair rental price for your property generally is an amount that a person who is not related to you would be willing to pay. The rent you charge is not a fair rental price if it is substantially less than the rents charged for other properties that are similar to your property.

Examples

The following examples show how to determine whether you used your rental property as a home.

Example 1. You converted the basement of your home into an apartment with a bedroom, a bathroom, and a small kitchen. You rented the basement apartment at a fair rental price to college students during the regular school year. You rent to them on a 9-month lease (273 days).

During June, your brothers stayed with you and lived in the basement apartment rent free.

Your basement apartment was used as a home because you used it for personal purposes for 30 days. Rent-free use by your brother is considered personal use. Your personal use (30 days) is more than the greater of 14 days or 10% of the total days it is rented (27 days).

Example 2. You rented out the guest bedroom in your home at a fair rental price during the local college’s homecoming, commencement, and football weekends (a total of 27 days). Your sister-in-law stayed in the room, rent free, for the last 3 weeks (21 days) in July.

The room was used as a home because you used it for personal purposes for 21 days. That is more than the greater of 14 days or 10% of the 27 days it is rented (3 days).

Example 3. You own a cottage in a resort area. You rented it out at a fair rental price for a total of 170 days during the year. For 12 of these days, the tenant was not able to use the cottage and allowed you to use it even though you did not refund any of the rent. Your family actually used the cottage for 10 of those days. Therefore, the cottage is treated as having been rented for 160 (170 − 10) days. Your family also used the cottage for 7 other days during the year.

You used the cottage as a home because you used it for personal purposes for 17 days. That is more than the greater of 14 days or 10% of the 160 days it was rented (16 days).

Use As Main Home Before or After Renting

Do not count as days of personal use the days you used the property as your main home before or after renting it or offering it for rent in either of the following circumstances.

1. You rented or tried to rent the property for 12 or more consecutive months.
2. You rented or tried to rent the property for a period of less than 12 consecutive months and the period ended because you sold or exchanged the property.

This special rule does not apply when dividing expenses between rental and personal use.

Figuring Days of Personal Use

A day of personal use of a dwelling unit is any day that it is used by any of the following persons.

1. You or any other person who has an interest in it, unless you rent it to another owner as his or her main home under a shared equity financing agreement (defined later).
2. A member of your family or a member of the family of any other person who has a financial interest in it, unless the family member uses the dwelling unit as his or her main home and pays a fair rental price. Family includes only brothers and sisters, half-brothers and half-sisters, spouses, ancestors (parents, grandparents, etc.) and lineal descendants (children, grandchildren, etc.).
3. Anyone under an arrangement that lets you use some other dwelling unit.
4. Anyone at less than a fair rental price.

Main home. If the other person or member of the family in (1) or (2) above has more than one home, his or her main home is the one lived in most of the time.

Shared equity financing agreement. This is an agreement under which two or more persons acquire undivided interests for more than 50 years in an entire dwelling unit, including the land, and one or more of the co-owners is entitled to occupy the unit as his or her main home upon payment of rent to the other co-owner or owners.

Donation of use of property. You use a dwelling unit for personal purposes if:

• You donate the use of the unit to a charitable organization,
• The organization sells the use of the unit at a fund-raising event, and
• The "purchaser" uses the unit.

Examples

The following examples show how to determine days of personal use.

Example 1. You and your neighbor are co-owners of a condominium at the beach. You rent the unit out to vacationers whenever possible. The unit is not used as a main home by anyone. Your neighbor uses the unit for two weeks every year.

Because your neighbor has an interest in the unit, both of you are considered to have used the unit for personal purposes during those 2 weeks.

Example 2. You and your neighbors are co-owners of a house under a shared equity financing agreement. Your neighbors live in the house and pay you a fair rental price.

Even though your neighbors have an interest in the house, the days your neighbors live there are not counted as days of personal use by you. This is because your neighbors rent the house as their main home under a shared equity financing agreement.

Example 3. You own a rental property that you rent to your son. Your son has no interest in this dwelling unit. He uses it as his main home. He pays you a fair rental price for the property.

Your son’s use of the property is not personal use by you because your son is using it as his main home, he has no interest in the property, and he is paying you a fair rental price.

Example 4. You rent your beach house to Joshua. Joshua rents his house in the mountains to you. You each pay a fair rental price.

You are using your house for personal purposes on the days that Joshua uses it because your house is used by Joshua under an arrangement that allows you to use his house.

Days Not Counted as Personal Use

Some days you spend at the dwelling unit are not counted as days of personal use.

Repairs and maintenance. Any day that you spend working substantially full time repairing and maintaining your property is not counted as a day of personal use. Do not count such a day as a day of personal use even if family members use the property for recreational purposes on the same day.

How To Divide Expenses

If you use a dwelling unit for both rental and personal purposes, divide your expenses between the rental use and the personal use based on the number of days used for each purpose. Expenses for the rental use of the unit are deductible under the rules explained in How To Figure Rental Income and Deductions, next.

When dividing your expenses follow these rules.

• Any day that the unit is rented at a fair rental price is a day of rental use even if you used the unit for personal purposes that day. This rule does not apply when determining whether you used the unit as a home.
• Any day that the unit is available for rent but not actually rented is not a day of rental use.

Example. You offer your beach cottage for rent from June 1 through August 31 (92 days). Your family uses the cottage during the last 2 weeks in May (14 days). You were unable to find a renter for the first week in August (7 days). The person who rented the cottage for July allowed you to use it over a weekend (2 days) without any reduction in or refund of rent. The cottage was not used at all before May 17 or after August 31.

You figure the part of the cottage expenses to treat as rental expenses as follows.

1. The cottage was used for rental a total of 85 days (92 − 7). The days it was available for rent but not rented (7 days) are not days of rental use. The July weekend (2 days) you used it is rental use because you received a fair rental price for the weekend.
2. You used the cottage for personal purposes for 14 days (the last 2 weeks in May).
3. The total use of the cottage was 99 days (14 days personal use + 85 days rental use).
4. Your rental expenses are 85/99 (86%) of the cottage expenses.

When determining whether you used the cottage as a home, the July weekend (2 days) you used it is personal use even though you received a fair rental price for the weekend. Therefore, you had 16 days of personal use and 83 days of rental use for this purpose. Because you used the cottage for personal purposes more than 14 days and more than 10% of the days of rental use, you used it as a home. If you have a net loss, you may not be able to deduct all of the rental expenses. See Property Used as a Home in the following discussion.

How To Figure Rental Income and Deductions

How you figure your rental income and deductions depends on whether the dwelling unit was used as a home and, if used as a home, how many days the property was rented.

Property Not Used As a Home

If you do not use a dwelling unit as a home, report all the rental income and deduct all the rental expenses. See How To Report Rental Income and Expenses, later.

Your deductible rental expenses can be more than your gross rental income. However, see Limits on Rental Losses, later. Table 10-1 Worksheet for figuring limit on rental deductions

Property Used As a Home

If you use a dwelling unit as a home during the year (see Dwelling Unit Used as Home, earlier), how you figure your rental income and deductions depends on how many days the unit was rented.

Rented fewer than 15 days. If you use a dwelling unit as a home and you rent it for fewer than 15 days during the year, do not include in income any of the rental income. Also, you cannot deduct any expenses as rental expenses.

Rented 15 days or more. If you use a dwelling unit as a home and rent it for 15 days or more during the year, you include all your rental income in your gross income. See How To Report Rental Income and Expenses, later. If you had a net profit from the rental property for the year (that is, if your rental income is more than the total of your rental expenses, including depreciation), deduct all of your rental expenses. However, if you had a net loss, you may not be able to deduct all of your rental expenses.

Use Table 10-1 to figure your deductible expenses.
