Sec. 1.513-2 Definition of unrelated trade or business applicable to taxable years beginning before December 13, 1967.

(1) As used in section 512(a), the term unrelated business taxable income includes only income from an unrelated trade or business regularly carried on, and the term trade or business has the same meaning as it has in section 162.

(2) The income of an exempt organization is subject to the tax on unrelated business income only if two conditions are present with respect to such income. The first condition is that the income must be from a trade or business which is regularly carried on by the organization. The second condition is that the trade or business must not be substantially related (aside from the need of the organization for income or funds or the use it makes of the profits derived) to the exercise or performance by such organization of its charitable, educational, or other purpose or function constituting the basis for its exemption under section 501, or in the case of an organization described in section 511(a)(2)(B) (governmental colleges, etc.) to the exercise or performance of any purpose or function described in section 501(c)(3). Whether or not an organization is subject to the tax imposed by section 511 shall be determined by the application of these tests to the particular circumstances involved in each individual case. For certain exceptions from the term unrelated trade or business, see paragraph (b) of this section.

(3) A trade or business is regularly carried on when the activity is conducted with sufficient consistency to indicate a continuing purpose of the organization to derive some of its income from such activity. An activity may be regularly carried on even though its performance is infrequent or seasonal.

(4) Ordinarily, a trade or business is substantially related to the activities for which an organization is granted exemption if the principal purpose of such trade or business is to further (other than through the production of income) the purpose for which the organization is granted exemption. In the usual case the nature and size of the trade or business must be compared with the nature and extent of the activities for which the organization is granted exemption in order to determine whether the principal purpose of such trade or business is to further (other than through the production of income) the purpose for which the organization is granted exemption. For example, the operation of a wheat farm is substantially related to the exempt activity of an agricultural college if the wheat farm is operated as a part of the educational program of the college, and is not operated on a scale disproportionately large when compared with the educational program of the college. Similarly, a university radio station or press is considered a related trade or business if operated primarily as an integral part of the educational program of the university, but is considered an unrelated trade or business if operated in substantially the same manner as a commercial radio station or publishing house. A trade or business not otherwise related does not become substantially related to an organization's exempt purpose merely because incidental use is made of the trade or business in order to further the exempt purpose. For example, the manufacture and sale of a product by an exempt college would not become substantially related merely because students as part of their educational program perform clerical or bookkeeping functions in the business. In some cases, the business may be substantially related because it is a necessary part of the exempt activity. For example, in the case of an organization described in section 501(c)(3) and engaged in the rehabilitation of handicapped persons, the business of selling articles made by such persons as a part of their rehabilitation training would not be considered an unrelated business since such business is a necessary part of the rehabilitation program.

(5) If an organization receives a payment pursuant to a contract or agreement under which such organization is to perform research which constitutes an unrelated trade or business, the entire amount of such payment is income from an unrelated trade or business. See, however, section 512(b), (7), (8), and (9), relating to the exclusion from unrelated business taxable income of income derived from research for the United States, or any State, and of income derived from research performed for any person by a college, university, hospital, or organization operated primarily for the purpose of carrying on fundamental research the results of which are freely available to the general public.

(1) Any trade or business in which substantially all the work in carrying on such trade or business is performed for the organization without compensation; or

(2) Any trade or business carried on by an organization described in section 501(c)(3) or by a governmental college or university described in section 511(a)(2)(B), primarily for the convenience of its members, students, patients, officers, or employees; or

(3) Any trade or business which consists of selling merchandise, substantially all of which has been received by the organization as gifts or contributions.
