The retirement plan landscape for small and mid-sized employers has changed dramatically in the wake of the SECURE Act, ushering in a new era of collaborative savings vehicles. For years, employers looked to Multiple Employer Plans (MEPs) to achieve economies of scale and reduce administrative burden. Yet MEPs carried drawbacks—most notably the “one bad apple” rule and complex eligibility constraints—that limited their appeal. Enter the Pooled Employer Plan (PEP), a new structure designed to broaden access, streamline execution, and sharpen fiduciary oversight. This article explores the pivotal differences between MEPs and PEPs, what the evolution means for plan sponsors, and how Pooled Plan Providers (PPPs) are reshaping the 401(k) plan structure through consolidated plan administration.
At their core, both MEPs and PEPs seek to deliver scale, lower costs, and improved Retirement plan administration for employers who would otherwise find a standalone 401(k) plan daunting. But the SECURE Act removed critical barriers to make PEPs both more accessible and more resilient, offering employers a clearer path to ERISA compliance without bearing the entire weight of plan governance individually.
What changed under the SECURE Act? Historically, MEPs required a common nexus or shared interest among participating employers, such as operating within the same industry or association. This limitation, combined with the “one bad apple” problem—where a compliance failure by one employer could jeopardize the entire plan—deterred many from participating. The SECURE Act introduced PEPs, which do not require a commonality of interest, while also establishing rules to isolate compliance issues to the offending employer, significantly reducing systemic risk. The result is a broader, more inclusive option for employers across industries who want to outsource much of the operational risk and complexity that come with a qualified plan.
Central to the PEP model is the Pooled Plan Provider. The PPP serves as the primary named fiduciary and plan administrator for the PEP, taking on responsibilities that individual employers would normally shoulder in a single-employer 401(k). This includes critical functions like vendor selection and monitoring, oversight of service providers, coordination of audit requirements, and ongoing Plan governance under ERISA. For many employers, this shift is transformative: instead of managing a full suite of fiduciary duties internally, they can rely on a PPP with dedicated expertise and systems designed for scalable, Consolidated plan administration.
Still, PEPs are not a complete set-it-and-forget-it solution. Employers participating in a PEP remain responsible for certain fiduciary obligations, such as prudently selecting the PEP and PPP, monitoring ongoing performance, and ensuring timely and accurate payroll data. But the day-to-day Retirement plan administration and Fiduciary oversight that typically strain in-house teams can be materially reduced. This “divide and conquer” approach often results in fewer administrative errors, more consistent ERISA compliance, and a clearer accountability framework.
From a cost standpoint, PEPs can unlock efficiencies that are hard to achieve with standalone plans. Pooling assets and standardizing the 401(k) plan structure gives PPPs leverage in vendor negotiations, potentially delivering lower investment and recordkeeping fees. In addition, consolidated audits and standardized documentation can simplify annual filings and reduce duplicative expenses. While fee outcomes vary by market and plan size, the trend line is favorable: when operational processes and oversight are centralized, both costs and risks tend to decrease.
Investment oversight is another area where PEPs aim to add value. Depending on the PEP design, the PPP or a designated investment fiduciary may assume the role of ERISA section 3(38) investment manager or 3(21) co-fiduciary, providing a robust framework for manager selection, monitoring, and replacement. For employers that lack in-house investment committees, this can be a meaningful improvement in Fiduciary oversight and documentation. However, employers should review the specific delegation model and confirm where the buck stops—especially around investment policy, default options, and fee benchmarking.
Plan design flexibility is a key consideration. MEPs often suffered from rigid terms to maintain uniformity, while standalone plans offered broader customization. PEPs typically strike a middle ground: standardized core features for operational efficiency, with selectable options for things like eligibility, employer match, auto-enrollment, and auto-escalation. The degree of flexibility varies from one PEP to another, so employers should assess whether a candidate PEP can accommodate their workforce needs without introducing undue complexity. The best PEPs balance efficiency with enough configurability to support real-world HR and talent strategies.
Compliance and audit processes also improve under the PEP framework. The PPP is generally responsible for coordinating filings like the Form 5500 for the plan as a whole, along with any required audits. Employers may still have employer-specific data or testing requirements, but the heavy lifting is centralized. That consolidated oversight reduces the risk of missed deadlines and disjointed processes—longstanding pain points in the Retirement plan administration of smaller employers.
Not all PPPs are created equal, and due diligence is essential. Employers should https://pep-structural-insights-workforce-trends-field-guide.iamarrows.com/employee-benefits-enhancement-attract-talent-with-a-pep evaluate the PPP’s experience, financial stability, service model, technology integration, and history with ERISA compliance. Ask how the PPP handles operational errors, participant communications, cybersecurity, and payroll integration. Understanding service-level agreements and indemnification terms is critical, as is clarity on who is named as the plan’s fiduciaries and administrators in the governing documents. A strong PPP will provide transparent fee structures, performance reporting, and an escalation path for issues.
For professional service firms, franchises, and distributed workforces, PEPs can be particularly attractive. They offer a path to on-board multiple related entities or new offices without reinventing the 401(k) plan structure each time. In mergers or roll-ups, PEPs can streamline integration, standardized governance, and consolidate vendors quickly, reducing distraction and risk during corporate change.
That said, MEPs still have a role. Trade associations and industry groups may continue to sponsor MEPs to serve a defined community with a shared mission. Some employers prefer the tighter affinity and shared governance model that a MEP can provide. Additionally, employers with highly customized plan features or unique compensation structures may still find standalone plans more suitable than either a MEP or a PEP.
Looking ahead, market adoption of PEPs is likely to accelerate as more PPPs demonstrate successful track records and as employers prioritize risk transfer and operational efficiency. The industry is also maturing around data exchange standards and payroll integrations that reduce errors and exceptions. As these plumbing improvements take hold, the promise of Consolidated plan administration—cleaner processes, consistent ERISA compliance, and improved participant outcomes—becomes easier to realize.
In short, the evolution from MEPs to PEPs under the SECURE Act marks a thoughtful modernization of retirement plan policy. By enabling credible third parties to shoulder more of the responsibility, the legislation strengthens Plan governance and expands access to high-quality, cost-effective retirement solutions. Employers considering their next move should map their objectives—cost, flexibility, risk tolerance, and HR strategy—against the capabilities of specific PEPs and PPPs. With careful selection and ongoing oversight, PEPs can deliver the right balance of control and convenience, freeing teams to focus on their core business while elevating the retirement benefits experience for employees.
Questions and answers:
- What is the main difference between a MEP and a PEP? A Multiple Employer Plan generally required a commonality of interest and historically exposed all participating employers to the “one bad apple” risk. A Pooled Employer Plan, enabled by the SECURE Act, removes the commonality requirement and isolates compliance issues to the responsible employer, with a Pooled Plan Provider taking primary administrative and fiduciary roles. What responsibilities does a PPP typically handle? The Pooled Plan Provider usually serves as the named fiduciary and plan administrator, overseeing vendor selection, investment oversight (directly or via a designated fiduciary), filings and audits, participant communications, and day-to-day Retirement plan administration under ERISA. Do employers still have fiduciary duties in a PEP? Yes. Employers must prudently select and monitor the PEP and PPP, ensure accurate and timely payroll data and contributions, and oversee any retained functions. PEPs reduce, but do not eliminate, employer fiduciary responsibilities. Are PEPs always cheaper than standalone plans? Not always. PEPs often leverage scale for better pricing and Consolidated plan administration, but actual costs depend on plan size, design options, vendor mix, and service levels. A side-by-side fee and service comparison is essential. How should an employer evaluate a potential PEP? Review the 401(k) plan structure, fiduciary designations, ERISA compliance history, technology and payroll integrations, investment oversight model, fee transparency, service-level commitments, and the PPP’s financial strength and experience.
