The Legal Framework of PEPs: Key ERISA and IRS Considerations
The introduction of the Pooled Employer Plan (PEP) under the SECURE Act marked a pivotal evolution in the retirement plan landscape, enabling unrelated employers to band together under a single, consolidated plan administration. By leveraging a Pooled Plan Provider (PPP), employers—particularly small and mid-sized businesses—can access scalable retirement plan administration, streamline fiduciary oversight, and reduce the complexity traditionally associated with a 401(k) plan structure. Yet, a PEP is not simply a repackaged Multiple Employer Plan (MEP); it carries its own legal architecture, fiduciary roles, and compliance obligations under ERISA and the Internal Revenue Code. Understanding these dimensions is essential for any employer considering adoption or for advisors guiding plan governance decisions.
PEPs vs. MEPs: What Changed Under the SECURE Act Before the SECURE Act, the open MEP—allowing unrelated employers to participate—was hampered by the “one bad apple” rule and association requirements. The SECURE Act explicitly authorized PEPs and appointed the PPP as a central fiduciary for plan operations, addressing historical barriers to entry. Critically, the law also introduced relief from the unified disqualification risk by permitting the IRS to apply disqualification or sanctions on a participating employer’s portion without collapsing the entire plan if procedures are followed. While PEPs share the collective scale of a MEP, their operational design and role of the PPP make them distinct.
Role and Responsibilities of the Pooled Plan Provider The PPP is the linchpin of a PEP. To function legally, a PPP must register with the Department of Labor (DOL) and the Treasury, typically by filing the appropriate registration forms and maintaining ongoing eligibility. The PPP is named as a plan fiduciary and plan administrator under ERISA, tasked with ensuring that the PEP’s plan document is compliant, service providers are prudently selected and monitored, and that required filings—such as the Form 5500 for the consolidated plan administration—are completed accurately and on time.
However, the PPP’s responsibilities do not absolve participating employers of all duties. Employers still retain fiduciary responsibility for prudently selecting and monitoring the PPP and any other delegated fiduciaries, and for ensuring accurate and timely remittance of employee deferrals. Employers may also maintain certain discretionary functions depending on how the plan governance is structured, such as eligibility determinations tied to workforce practices.
Plan Governance and Fiduciary Oversight Effective plan governance in a PEP environment hinges on clearly articulated roles in the plan document and service agreements. The PPP commonly assumes 3(16) plan administrator responsibilities, and an investment fiduciary (e.g., an ERISA 3(38) or 3(21) advisor) may be engaged to manage plan investments. Some PEPs incorporate a discretionary 3(38) manager to centralize investment menu decisions for the entire plan, harmonizing the 401(k) plan structure across adopting employers.
From a fiduciary oversight perspective, there are several best practices:
- Maintain a documented process for selecting and monitoring the PPP and investment fiduciaries. Review service agreements for indemnification limits, fee transparency, cybersecurity representations, and performance standards. Ensure payroll integration processes are robust to avoid late deposits and operational defects. Periodically review fee reasonableness at both the plan level and employer-specific level, especially if there are employer-specific services. Validate that employee communications and disclosures are timely and compliant under ERISA and the DOL’s e-disclosure framework.
ERISA Compliance Considerations ERISA compliance in a PEP includes all familiar responsibilities—such as adherence to plan document terms, disclosure obligations, claims procedures, and prohibited transaction rules—applied in a consolidated structure. The PPP’s oversight of operational processes is especially critical for:
- Timely deposit of employee contributions and loan repayments. Accurate application of eligibility, deferral elections, and employer contributions. Monitoring of service provider relationships, including recordkeeping, trust/custody, and advisory services. Managing corrections through the DOL’s Voluntary Fiduciary Correction Program or IRS correction programs when necessary.
A unique compliance advantage of the PEP model is consolidated plan administration, which can reduce duplicative filings and audits. Typically, the PEP files a single Form 5500 with an audit based on the plan’s overall size, not each adopting employer separately. Still, employers may need to provide employer-level data to support the PPP’s filings and audits.
IRS and Qualification Rules: Testing, Document Maintenance, and the “Bad Apple” Fix PEPs must meet the qualification requirements of the Internal Revenue Code, including coverage and nondiscrimination testing, contribution limits, and distribution rules. Depending on the PEP’s design, testing may occur at the aggregated plan level or on an employer-by-employer basis to prevent cross-subsidization and ensure fairness. The SECURE Act’s “bad apple” relief allows the IRS to isolate failures attributable to a noncompliant employer, provided the PEP follows mandated procedures to correct or eject that employer. This structure protects other participating employers from cascading qualification risks.
Document maintenance is another cornerstone. The PPP is responsible for maintaining a pre-approved or individually designed plan document and ensuring timely interim and remedial amendments to reflect legal changes. Employers must adopt a participation agreement that aligns their workforce policies with the PEP’s terms, specifying eligibility, match formulas, and other employer-level choices.
Operational Risk Management and Cybersecurity Centralization does not eliminate operational risk; it shifts and concentrates it. Payroll integration, data integrity, and secure data exchanges between employers, payroll providers, and recordkeepers are essential. The DOL has issued cybersecurity guidance applicable to retirement plan administration, and PPPs should demonstrate robust policies, incident response plans, third-party oversight, and participant education regarding account security. Employers, as fiduciaries, should request and evaluate this documentation.
Fee Structures and Benchmarking PEPs often feature tiered pricing that benefits from economies of scale. The PPP may bundle certain fiduciary services, recordkeeping, and investment oversight. Employers should evaluate total plan cost, including the PPP fee, recordkeeping charges, investment expense ratios, and any employer-specific add-ons. Fee benchmarking at regular intervals remains an ERISA best practice, even with a consolidated plan administration model delivering scale.
Participant Experience and 401(k) Plan Structure From the participant’s perspective, a well-run PEP should deliver a consistent 401(k) plan structure with a clear investment menu, target-date funds or managed accounts, and intuitive tools. Auto-features—auto-enrollment, auto-escalation, and re-enrollment—can be implemented plan-wide, though employers may have limited tailoring options depending on the PEP’s governance framework. Clarity in communications about plan features, vesting, eligibility, and employer contributions is critical to avoid confusion across a diverse set of adopting employers.
Transitioning Into a PEP Employers moving from a standalone plan or from a MEP to a PEP should follow a structured transition:
- Conduct fiduciary due diligence on the PPP and investment fiduciaries. Map investments and loans, and reconcile payroll and eligibility data. Review plan design elections in the participation agreement to align with workforce strategy. Establish an internal control matrix for payroll remittance and data quality. Set a communication plan for employees regarding blackout periods, changes in providers, and new features.
Looking Ahead: Regulatory Developments PEPs continue to evolve as the DOL and IRS refine guidance on reporting, disclosure, and operational compliance. Future enhancements may streamline employer onboarding, sharpen the mechanics of the “bad apple” relief, and expand electronic disclosure frameworks.

Questions and Answers
Q1: How does a PEP reduce employer fiduciary burden compared to a standalone plan? A: The PPP assumes key fiduciary and administrative responsibilities—such as ERISA plan administration, vendor monitoring, and consolidated filings—while the employer focuses on selecting and monitoring the PPP and ensuring accurate payroll remittances.
Q2: Is the “one bad apple” rule eliminated for PEPs? A: The SECURE Act provides relief that allows the IRS to isolate compliance failures to the responsible employer if the PEP follows prescribed correction or ejection procedures, protecting other employers in the plan.
Q3: Do employers still need an audit under a PEP? A: The PEP typically files a single Form 5500 with an audit at the plan level. Individual employers generally do not undergo separate plan audits, though they must supply data to support the consolidated audit.
Q4: Can employers customize plan design in a PEP? A: Yes, within the limits of the PEP’s framework. Employers make elections in a participation agreement (e.g., match formula, eligibility), but some elements are standardized to maintain operational efficiency.
Q5: What should employers review when selecting a PPP? A: Evaluate the PPP’s registration status, fiduciary experience, fee structure, cybersecurity program, service model, investment oversight framework, compliance track record, and references, and document the selection process for ERISA compliance.
