(a) General definition. Gross income means all income from whatever source derived, unless excluded by law. Gross income includes income realized in any form, whether in money, property, or services. Income may be realized, therefore, in the form of services, meals, accommodations, stock, or other property, as well as in cash. Section 61 lists the more common items of gross income for purposes of illustration. For purposes of further illustration, § 1.61-14 mentions several miscellaneous items of gross income not listed specifically in section 61. Gross income, however, is not limited to the items so enumerated.
