1220.1 How is rental income calculated for more than one property?
Rental income from two or more property operations is treated separately in figuring net earnings from self-employment. Your rental income does not count for Social Security purposes even if you have income from another property, such as a boardinghouse, which is included in earnings from self-employment.
1220.2 If part of the property is rented with services and part is rented without services, how is income calculated?
If you rent part of your property and provide significant services and part without such services, consider each separately. Income from the property rented with services is counted while the income from the other property is not counted. You should charge the expenses attributable to each type of operation accordingly.
