Reg. § 1.501(c)(5)-1 Labor, agricultural, and horticultural organizations.
(a) The organizations contemplated by section as entitled to exemption from income taxation are those which:
(1) Have no net earnings inuring to the benefit of any member, and
(2) Have as their objects the betterment of the conditions of those engaged in such pursuits, the improvement of the grade of their products, and the development of a higher degree of efficiency in their respective occupations.
(b)
(1) General rule An organization is not an organization described in section if the principal activity of the organization is to receive, hold, invest, disburse or otherwise manage funds associated with savings or investment plans or programs, including pension or other retirement savings plans or programs.
(2) Exception of this section shall not apply to an organization which—
(i) Is established and maintained by another labor organization described in section (determined without regard to this );
(ii) Is not directly or indirectly established or maintained in whole or in part by one or more—
(A) Employers;
(B) Governments or agencies or instrumentalities thereof; or
(C) Government controlled entities;
(iii) Is funded by membership dues from members of the labor organization described in this and earnings thereon; and
(iv) Has not at any time after September 2, 1974 (the date of enactment of the Employee Retirement Income Security Act of 1974, Pub. L. 93-406, 88 Stat. 829) provided for, permitted or accepted employer contributions.
(3) Example The principles of this are illustrated by the following example:
Example. Trust A is organized in accordance with a collective bargaining agreement between labor union K and multiple employers. Trust A forms part of a plan that is established and maintained pursuant to the agreement and which covers employees of the signatory employers who are members of K. Representatives of both the employers and K serve as trustees. A receives contributions from the employers who are subject to the agreement. Retirement benefits paid to K's members as specified in the agreement are funded exclusively by the employers' contributions and accumulated earnings. A also provides information to union members about their retirement benefits and assists them with administrative tasks associated with the benefits. Most of A's activities are devoted to these functions. From time to time, A also participates in the renegotiation of the collective bargaining agreement. A's principal activity is to receive, hold, invest, disburse, or otherwise manage funds associated with a retirement savings plan. In addition, A does not satisfy all the requirements of the exception described in of this section. (For example, A accepts contributions from employers.) Therefore, A is not a labor organization described in section .
(c) Organizations described in section and otherwise exempt from tax under section are taxable upon their unrelated business taxable income. See part II (section and following), subchapter F, chapter 1 of the Code, and the regulations thereunder.
