Employees of partnerships, proprietorships, etc., which are under common control

(A) General rule Except as provided in subparagraphs (B) and (C), for purposes of this subsection and subsection (m), an organization that is otherwise eligible to participate in a church plan shall not be aggregated with another such organization and treated as a single employer with such other organization for a plan year beginning in a taxable year unless— (i) one such organization provides (directly or indirectly) at least 80 percent of the operating funds for the other organization during the preceding taxable year of the recipient organization, and (ii) there is a degree of common management or supervision between the organizations such that the organization providing the operating funds is directly involved in the day-to-day operations of the other organization.

(B) Nonqualified church-controlled organizations Notwithstanding subparagraph (A), for purposes of this subsection and subsection (m), an organization that is a nonqualified church-controlled organization shall be aggregated with 1 or more other nonqualified church-controlled organizations, or with an organization that is not exempt from tax under section 501, and treated as a single employer with such other organization, if at least 80 percent of the directors or trustees of such other organization are either representatives of, or directly or indirectly controlled by, such nonqualified church-controlled organization. For purposes of this subparagraph, the term “nonqualified church-controlled organization” means a church-controlled tax-exempt organization described in section 501(c)(3) that is not a qualified church-controlled organization (as defined in section 3121(w)(3)(B)).

(C) Permissive aggregation among church-related organizations The church or convention or association of churches with which an organization described in subparagraph (A) is associated (within the meaning of subsection (e)(3)(D)), or an organization designated by such church or convention or association of churches, may elect to treat such organizations as a single employer for a plan year. Such election, once made, shall apply to all succeeding plan years unless revoked with notice provided to the Secretary in such manner as the Secretary shall prescribe.

(D) Permissive disaggregation of church-related organizations For purposes of subparagraph (A), in the case of a church plan, an employer may elect to treat churches (as defined in section 403(b)(12)(B)) separately from entities that are not churches (as so defined), without regard to whether such entities maintain separate church plans. Such election, once made, shall apply to all succeeding plan years unless revoked with notice provided to the Secretary in such manner as the Secretary shall prescribe.
