An affiliated service group is one type of group of related employers and refers to two or more organizations that have a service relationship and, in some cases, an ownership relationship, described in IRC section 414(m). An affiliated service group can fall into one of three categories:
- A-Organization groups (referred to as “A-Org”), consists of an organization designated as a First Service Organization (FSO) and at least one “A organization”,
- B-Organization groups (referred to as “B-Org”), consists of a FSO and at least one “B organization”, or
- Management groups.
If businesses that are part of a controlled group do not meet the percentage requirements that would result in common control, they may still need to be treated as one employer for retirement plan purposes, because of the affiliation resulting in an ASG between the businesses.
To obtain some assurance whether they are part of an affiliated service group, employers/plan sponsors may obtain a determination from the IRS by filing IRS Form 5300- Application for Determination for Employee Benefit Plan.
The general rule of section 414(m) is that employees of employers that are members of an affiliated service group are considered to be employed by a single employer for purposes of certain provisions of section 401(a), and sections 408(k), 408(p), 410, 411, 415 and 416.

An attorney experienced in the area of ERISA should be consulted to determine whether an affiliated service group exists
If there is common ownership for both businesses, it could be determined that the businesses are part of a controlled group. However, determining whether an affiliated service group exists is a very complex process.
Section 414(m) was enacted to prevent circumvention of the controlled group rules by expanding the idea of control to separate, but affiliated, entities. Proposed Treas. Reg. § 1.414(m) provides that all employees of the members of an affiliated service group shall be treated as if a single employer employed them.
