The Future of Retirement Plans: Will PEPs Become the New Standard?

The Future of Retirement Plans: Will PEPs Become the New Standard?

The retirement landscape in the United States is undergoing quiet but significant change. For decades, employers—especially small and mid-sized businesses—have faced steep barriers to offering competitive plans: high fees, administrative complexity, and daunting fiduciary risk. But the introduction of the Pooled Employer Plan (PEP) under the SECURE Act created a new path: join a consolidated plan structure managed by a Pooled Plan Provider (PPP) and offload much of the operational and fiduciary burden. As employers seek more efficient ways to deliver benefits, many are asking whether PEPs are poised to become the default model.

To understand the potential, it helps to situate PEPs in the broader history of employer-sponsored retirement plans. Traditional single-employer 401(k) plan structure gives employers maximum flexibility—but at the cost of significant plan governance responsibilities, ERISA compliance obligations, investment oversight, and ongoing retirement plan administration. Multiple Employer Plans (MEPs) tried to offer scale by grouping employers together, but often required a “commonality” of interest and came with the “one bad apple” risk—where a failure by one employer could disqualify the entire plan. The SECURE Act modernized this terrain by enabling PEPs, which allow unrelated employers to join a single plan overseen by a registered PPP and avoid the commonality requirement and “bad apple” complications (provided certain compliance standards are met).

What makes PEPs compelling is their promise of consolidated plan administration. Employers that join a PEP typically delegate day-to-day tasks—eligibility tracking, payroll integration, loan processing, distributions, audit preparation, and annual filings—to the PPP or its affiliates. Many PPPs also assume key fiduciary functions, such as serving as the 3(16) plan administrator and engaging a 3(38) investment manager. This fiduciary oversight can materially reduce an employer’s exposure to claims related to operational failures or imprudent investment processes, which are increasingly the subject of class-action litigation in the ERISA space.

The potential advantages of a PEP extend across cost, risk, and participant outcomes:

Scale economics: By pooling assets and operations, PEPs can negotiate lower recordkeeping fees, investment expenses, and advisory costs. While savings vary, the structural leverage is real, especially for smaller plans that struggle to access institutional pricing. Streamlined operations: Consolidated plan administration reduces vendor management headaches and lowers the incidence of errors across payroll files, eligibility determination, and compliance testing. Enhanced governance: Delegating to specialists can improve plan governance discipline. A PPP, with formal processes and documentation, can more consistently manage ERISA compliance, investment monitoring, and annual reviews compared with ad hoc single-employer approaches. Audit simplification: Many PEPs centralize the annual audit process, potentially easing the administrative burden and cost for adopting employers.

However, PEPs are not a cure-all, and trade-offs matter. Employers considering a move must assess:

Loss of customization: A pooled structure necessarily standardizes plan design features. While many PEPs offer flexible options—auto-enrollment, match formulas, Roth features—there are limits. Complex eligibility groups, niche compensation definitions, or bespoke vesting may not fit. Vendor lock-in and transparency: While the PPP coordinates providers, employers should evaluate fee transparency, revenue-sharing practices, and the governance framework used to select and monitor service providers and investment options. Fiduciary clarity: PEPs can shift significant fiduciary responsibility to the PPP and affiliated fiduciaries, but employers remain responsible for prudently selecting and monitoring the PPP itself. Understanding precisely which fiduciary roles are delegated is essential. Transition complexity: Moving from a standalone 401(k) plan structure into a PEP involves document amendments, asset mapping, blackout periods, and employee communications. Careful planning minimizes disruption.

From a regulatory vantage point, PEPs are designed to be ERISA-compliant pooled arrangements with clear accountability. The PPP must register with the Department of Labor and is obligated to maintain documented processes for plan governance and ERISA compliance. This codified structure addresses many of the historical barriers that limited adoption of MEPs. Furthermore, evolving legislation—such as subsequent SECURE Act enhancements—continues to encourage small-business coverage and auto-enrollment features, suggesting policymakers favor models that expand participation and reduce administrative friction.

Will PEPs become the new standard? The answer likely depends on employer size and benefits philosophy:

Micro and small employers: For organizations with limited HR bandwidth and under $10–$20 million in plan assets, PEPs can be especially attractive. They offer turnkey retirement plan administration and scale-based pricing previously out of reach. As PPP offerings mature, adoption in this segment could become mainstream. Mid-market employers: Companies with more complex workforces often value flexibility. Many will weigh a PEP against enhanced bundled 401(k) arrangements that include 3(16)/3(38) support without sacrificing design control. PEPs that strike the right balance—offering modular features within a consolidated plan administration framework—can gain ground here. Large employers: With internal benefits teams and purchasing power, large plans already capture scale and may prefer bespoke governance and investment structures. For them, PEPs are less likely to become standard, though select divisions or acquired entities might onboard to a PEP for transition periods.

One underappreciated dimension is how PEPs could reshape the advisor and recordkeeper ecosystem. Advisors may pivot from custom, plan-by-plan design toward consultative selection and monitoring of PPPs, fee benchmarking within pooled programs, and participant outcomes strategies. Recordkeepers and asset managers may prioritize PEP-friendly technology and share classes that maximize scale benefits. If this realignment accelerates, PEPs could catalyze a more standardized, outcome-oriented market.

Another factor is litigation risk. The trend of fee and investment lawsuits has pushed employers to formalize fiduciary oversight. PEPs, with their embedded governance and defined roles, can reduce exposure—though not eliminate it. The market will closely watch how courts treat PPP decision-making and whether consolidated governance translates into fewer adverse outcomes.

Finally, employee experience remains paramount. Participants judge plans by ease of use, investment access, advice tools, and communication. PEPs that integrate high-quality managed accounts, intuitive digital experiences, and transparent fee structures can drive higher deferral rates and better outcomes. Conversely, a pooled plan with clunky service undermines the very advantages it claims.

So, will PEPs become the new standard? They are unlikely to fully displace single-employer 401(k) plan structures, especially among large and highly customized sponsors. But for a broad swath of small and mid-sized employers, PEPs are well-positioned to become a default pathway—delivering cost efficiency, robust fiduciary oversight, and simplified operations through consolidated plan administration. As PPP competition intensifies and best practices mature, the Pooled Employer Plan could quietly redefine how retirement benefits are delivered in the U.S.

Questions and Answers

1) What is the key difference between a PEP and a MEP?

A PEP allows unrelated employers to join a single plan without a commonality requirement, overseen by a registered PPP. Traditional MEPs often require commonality and historically carried “one bad apple” risk that could affect all employers if one failed compliance.

2) Does joining a PEP eliminate an employer’s fiduciary responsibilities?

No. A PEP can shift substantial fiduciary duties to the PPP and designated fiduciaries (e.g., 3(16) and 3(38)). However, the employer retains responsibility for prudently selecting and monitoring the PPP and understanding the scope of delegated duties.

3) Are PEPs more cost-effective than standalone plans?

Often, yes—especially for smaller employers—because pooled assets and operations can reduce recordkeeping, investment, and advisory fees. Actual savings depend on the PPP’s pricing, investment menu, and service model.

4) Can employers customize plan design within a PEP?

To a degree. Many PEPs offer options like match formulas, automatic enrollment, Roth contributions, and loans. Highly specialized eligibility rules or complex compensation definitions may be constrained by the pooled framework.

5) What should employers evaluate when selecting a PPP?

Review fee transparency, governance processes, ERISA compliance rigor, investment oversight approach, service levels, data integration with payroll, and the track record of the PPP and its providers.
