What Nonprofit Boards Should Know About 403(b) Pooled Employer Plans

By Nikki Hamblin, on November 2nd, 2026

Offering a competitive retirement benefit has never been more important…or more complicated. As fiduciary and compliance obligations continue to grow, many nonprofit organizations are tasked with managing increasingly complex retirement plans with limited internal resources.

The problems are real, but one solution is gaining significant attention: the 403(b) Pooled Employer Plan (PEP). While PEPs have gained considerable traction in the 401(k) marketplace, they can be equally compelling for nonprofit organizations seeking to streamline retirement plan administration, reduce fiduciary risk, and enhance the retirement plan experience for employees.

What Is a 403(b) Pooled Employer Plan (PEP)?

A PEP is a retirement plan structure in which multiple unrelated employers participate in a single retirement plan overseen by a professional Pooled Plan Provider (PPP).

Instead of each organization maintaining its own standalone plan and assuming full responsibility for many administrative, compliance, and fiduciary functions, participating employers join a larger arrangement that delegates numerous plan management responsibilities to retirement plan professionals.

The employer’s primary fiduciary responsibility in a PEP is to prudently select and monitor the PPP, which serves as the plan sponsor and is responsible for appointing and overseeing many of the plan’s key service providers and fiduciaries.

These may include a 3(38) investment manager responsible for investment oversight, and a 3(16) fiduciary handling plan administration. Supporting these fiduciary roles are providers such as the recordkeeper, which manages participant accounts, and the third-party administrator (TPA), which oversees compliance and testing requirements.

Key Benefits of 403(b) Pooled Employer Plans for Nonprofits

PEPs can help nonprofits reduce administrative and fiduciary burdens, allowing them to focus more time and resources on advancing their mission while continuing to provide a valuable retirement benefit.

Reduce Retirement Plan Administrative Burden

Many day-to-day administrative responsibilities are centralized within the PEP, reducing the time internal staff spend managing the retirement plan. Participating employers may also avoid the need for a standalone plan audit and Form 5500 filing, helping lower costs and complexity.

Reduce Fiduciary Risk & Responsibilities

Nonprofit boards should understand that they may be fiduciaries for their organization’s retirement plan. A PEP can transfer key duties such as plan administration, provider due diligence and investment oversight to professional fiduciaries, significantly reducing risk and governance demands.

Enhance the Retirement Plan Participant Experience

Participants may benefit from enhanced education resources, planning tools, and institutional-quality investment options that can be difficult for smaller plans to provide on their own.

Gain Cost Efficiencies Through Economies of Scale

By joining a larger pooled arrangement, organizations can often access services, resources, and pricing that may not be available through a standalone plan.

Transition Existing 403(b) Plans to a PEP

Organizations with existing plans and legacy assets can often transition to a PEP. In many cases, prior plan balances can remain intact, making the move more seamless than nonprofit boards and management may expect.

What Nonprofits Should Consider When Evaluating a 403(b) PEP

Boards should recognize that not all PEPs are created equal. It is essential to understand which responsibilities remain with your organization and whether that structure makes sense for your board, staff, and participants.

When evaluating potential providers, boards should consider:

  • Who serves as the PPP? Does the PPP have any conflicts of interest?
  • Who is accepting 3(16) fiduciary responsibility?
  • Is the 3(38) investment manager experienced? Who selects and monitors the 3(38)?
  • Which responsibilities remain with the employer?

The answers to these questions can help determine whether a particular PEP is aligned with best practices to support an organization’s needs and employee outcomes.

Is a 403(b) Pooled Employer Plan Right for Your Nonprofit?

For many nonprofit organizations, 403(b) Pooled Employer Plans represent a compelling opportunity to modernize retirement plan administration while strengthening fiduciary governance.

Although a PEP is not the right solution for every organization, boards and nonprofit leadership teams should understand how these arrangements can reduce administrative strain, enhance oversight, and support employees’ long-term retirement readiness.

As retirement plan responsibilities continue to evolve, proactive evaluation of available options can help ensure your organization’s benefit strategy remains aligned with both its mission and its fiduciary obligations.
