Recently, the Department of Labor (DOL) published final rules clarifying the circumstances under which “bona fide” groups or associations of employers and professional employer organizations (PEOs) may be permitted to sponsor single defined contribution multiple employer plans (MEPs). Concurrently, the Internal Revenue Service (IRS) published proposed rules detailing an exception to the “one bad apple” rule for defined contribution MEPs, which rule provides that the failure of one employer to meet established qualification requirements results in the disqualification of the MEP for all participating employers.
