For many employers, the appeal of joining a Pooled Employer Plan (PEP) lies in simplifying retirement plan administration, accessing institutional pricing, and reducing fiduciary burden. But while PEPs streamline much of the operational complexity, ERISA compliance remains a central responsibility that cannot be ignored. Understanding how PEPs, introduced by the SECURE Act, change the landscape—especially when compared with a Multiple Employer Plan (MEP) or a standalone 401(k) plan structure—helps employers make informed, defensible decisions.
Below is a practical guide to ERISA expectations in a PEP, how fiduciary oversight really works, and what employers should evaluate when selecting a Pooled Plan Provider (PPP).
Body
1) What a PEP Is—and Is Not
- A PEP is a single, consolidated plan administration framework that allows unrelated employers to participate in one retirement plan overseen by a registered Pooled Plan Provider (PPP). Unlike legacy MEPs, PEPs do not require a common nexus among employers and were designed by the SECURE Act to remove historical barriers like the “one bad apple” rule, which had previously threatened disqualification of the entire plan due to one employer’s compliance failure. A PEP does not eliminate ERISA compliance obligations. Rather, it reallocates many duties from the employer to the PPP and other named fiduciaries. Employers retain fiduciary responsibility for prudently selecting and monitoring the PEP and the PPP.
2) Key ERISA Roles in a PEP
- Pooled Plan Provider (PPP): The PPP is the plan’s ERISA-designated fiduciary responsible for plan governance, day-to-day oversight, and ensuring the plan is administered in accordance with ERISA and the plan document. The PPP must register with the Department of Labor (DOL) and the Treasury and is typically responsible for filing the Form 5500 on behalf of the PEP. Named Fiduciaries and 3(16)/3(38) Providers: Many PEPs engage an ERISA 3(16) administrator to handle operational fiduciary functions and a 3(38) investment manager to assume discretionary control over the investment lineup. This can meaningfully reduce employer fiduciary exposure, though not eliminate it. Participating Employers: Employers retain fiduciary oversight for selecting and monitoring the PEP, the PPP, and the investment/administrative providers. They also remain responsible for accurate and timely payroll data, eligibility determinations as required by the plan, and remittance of employee deferrals.
3) ERISA Compliance Priorities for Employers in a PEP
- Prudence in Selection and Monitoring: Document the due diligence process used to select the PEP. Review PPP registrations, experience, fee structures, service-level agreements, audit results, and participant outcomes. Establish a monitoring calendar—at least annually—to review performance, fees, operational errors, and any litigation or DOL inquiries. Fee Reasonableness: Even in a consolidated plan administration model, employers must ensure fees are reasonable relative to services. Compare the PEP’s all-in cost (administration, recordkeeping, audit, investment, advisory) against benchmarks and similar solutions. Investment Oversight (via Delegation): If the PEP uses a 3(38) investment manager, confirm the investment policy statement (IPS) and replacement criteria. Request periodic reporting on investment performance, fees, and share classes. Ensure revenue-sharing is accounted for and that any float or ancillary compensation is disclosed. Payroll and Data Integrity: Most PEP operational issues—late deferrals, incorrect eligibility, payroll file errors—originate at the employer. Build controls for timely remittance, coordinate with payroll vendors, and validate participant-level data. This is core to ERISA compliance and cannot be fully outsourced. Participant Communications: Confirm that the PEP’s notices—QDIAs, fee disclosures, safe harbor notices, automatic enrollment/escallation disclosures—are sent timely and accurately. Employers should track delivery schedules and maintain evidence of distribution. Corrective Procedures: Understand how the PPP handles errors, including the use of the IRS’s EPCRS and the DOL’s VFCP programs. Ask for written processes, turnaround times, and examples of past corrections.
4) Comparing PEPs to MEPs and Single-Employer 401(k) Plans
- Versus MEPs: The modern PEP structure resolves the historical commonality requirement and mitigates the “one bad apple” risk. Administration is centralized, and fiduciary roles are clearer. Some closed MEPs may still offer competitive pricing, but PEPs are generally more accessible. Versus a Standalone 401(k) Plan Structure: A PEP can reduce employer burden by outsourcing plan governance and investment discretion, streamline audits through aggregated filings, and potentially lower costs through pooled purchasing. However, standalone plans may offer more customization and direct control over plan features. Suitability: Employers with limited internal resources for retirement plan administration or those seeking to reduce committee workload often favor PEPs. Employers that require bespoke plan design, custom eligibility rules, or unique investment menus may lean toward a single-employer plan.
5) Plan Governance Under a PEP
- Governance Documentation: Request the PEP’s plan document, trust agreement, IPS, service agreements, SOC 1/SOC 2 reports (if applicable), and fiduciary committee charters. Confirm who is the named fiduciary, trustee, 3(16), and 3(38). Meeting Cadence: Even with consolidated plan administration, employers should conduct at least annual reviews with the PPP and recordkeeper. Keep minutes showing you evaluated fees, services, participant outcomes, operational errors, and plan design. Cybersecurity and Data Privacy: Evaluate the PEP’s cybersecurity program following DOL guidance—vendor management, access controls, encryption, incident response, and cyber insurance. Payroll data integration amplifies risk; make sure controls are tested. Audit Readiness: Most large PEPs undergo a single plan audit, which can reduce employer audit burden. Still, employers should retain payroll and remittance documentation and cooperate with auditor data requests routed through the PPP.
6) Practical Steps to Implement and Monitor a PEP
- Pre-Adoption Checklist: Compare proposals from at least two PEPs and a standalone 401(k) plan. Map responsibilities: who does eligibility, loans, QDROs, hardship reviews, corrections, and Form 5500? Review fee schedules and revenue-sharing offsets; confirm share classes and managed account pricing. Validate the PPP’s fiduciary insurance and bonding. Post-Adoption Controls: Calendar key dates: payroll remittances, compliance testing cycles, and notice deadlines. Reconcile census and hours data quarterly to reduce testing errors. Conduct an annual fiduciary review with the PPP; document decisions and any changes. Test payroll system changes in a nonproduction environment before go-live.
7) Common Pitfalls and How to Avoid Them
- Assuming All Risk Is Transferred: Delegation reduces but does not eliminate fiduciary responsibility. Maintain an oversight process. Incomplete Payroll Integration: Establish file specs, test files, and monitor confirmations to avoid contribution errors and late deposits. Neglecting Plan Design Reviews: PEPs often offer standardized features. Reassess auto-enrollment rates, employer match formulas, and eligibility to align with workforce objectives. Overlooking Operational Errors: Use periodic quality checks—loans, hardship distributions, and reinstatement after leaves of absence—to prevent small mistakes from compounding.
8) The Bottom Line PEPs, enabled by the SECURE Act, can offer significant advantages: consolidated plan administration, professional fiduciary oversight, and potentially lower costs. But ERISA compliance still hinges on prudent selection and ongoing monitoring of the PEP, the PPP, and related service providers. Employers that establish disciplined governance, validate payroll processes, and document oversight will be well positioned to capture the benefits of a PEP while managing risk effectively.
Questions and Answers
Q1: Does joining a PEP eliminate my fiduciary responsibilities under ERISA? A: No. A PEP shifts many duties to the PPP and other named fiduciaries, but employers retain fiduciary oversight for selecting and monitoring the PEP and ensuring payroll and participant data are accurate and timely.
Q2: How do PEP fees compare to a standalone 401(k) plan? A: PEPs may offer lower all-in costs due to scale https://rentry.co/qtw6w5rg and consolidated services, but you must benchmark fees against comparable options and verify that investment share classes and revenue-sharing are optimized.
Q3: What should I look for in a Pooled Plan Provider (PPP)? A: Confirm registration status, experience, service model, SOC reports, error correction procedures, cybersecurity controls, fiduciary insurance, and transparent fee disclosures. Ask for references and sample reporting.
Q4: Can I customize plan design within a PEP? A: Many PEPs offer standardized plan features with limited customization. Evaluate whether the available options align with your workforce needs; if not, a standalone 401(k) plan structure may be preferable.
Q5: How are audits handled in a PEP? A: Large PEPs typically undergo a single plan audit, which can reduce employer burden. Employers still need to maintain accurate records and coordinate with the PPP on auditor requests.
