What Responsibilities Does an Employer Keep After Joining a Pooled Employer Plan?
Joining a PEP can significantly reduce administrative and fiduciary burden—but it doesn’t eliminate it. Here’s what every retirement plan committee should continue monitoring.
Joining a Pooled Employer Plan (PEP) is often described as a way to reduce fiduciary burden. That’s true—but it’s also one of the easiest places for retirement plan committees to develop a false sense of security.
Many employers hear phrases like “outsource fiduciary responsibility” or “the pooled plan provider handles everything,” and understandably assume their work is largely finished. After all, that’s one of the biggest selling points of a PEP.
But under ERISA, delegation and elimination are two very different things.
While a PEP can significantly reduce day-to-day fiduciary responsibilities, it does not eliminate an employer’s fiduciary obligations altogether. In fact, the decision to join a PEP is itself a fiduciary act—and so is the ongoing responsibility to monitor whether the arrangement continues to serve participants’ best interests.
Understanding where those responsibilities begin and end is one of the most important governance conversations a retirement plan committee can have.
What Is a Pooled Employer Plan?
A Pooled Employer Plan allows multiple unrelated employers to participate in a single retirement plan administered by a Pooled Plan Provider (PPP or “P3”).
The structure was created under the SECURE Act to simplify retirement plan administration by centralizing many fiduciary and administrative responsibilities.
Depending on how the PEP is structured, the Pooled Plan Provider may assume responsibility for areas such as:
- Selecting and monitoring investment managers
- Hiring and overseeing service providers
- Plan administration
- Fiduciary governance
- Operational compliance
- Certain ERISA reporting requirements
For many employers, that’s a significant improvement over managing every responsibility internally.
But there’s an important distinction:
The employer is delegating responsibilities—not abandoning them.
If you’re still comparing a traditional retirement plan to a PEP, our guide to Pooled Employer Plans explains how the structure works and when it may be appropriate for employers.
The Biggest Misconception About PEPs
One of the most common misunderstandings we hear is:
“We’re in a PEP now, so we don’t really have fiduciary liability anymore.”
That’s rarely true.
Even the best-designed PEPs leave certain responsibilities with the adopting employer. Those retained duties vary depending on the governing agreements, which is why reading the actual contracts—not just the proposal—is so important.
Marketing materials explain the benefits.
Contracts define the liability.
And those two documents don’t always say exactly the same thing.
We’ve also discussed this topic in greater depth on The Wise Fiduciary Podcast, where we explore why delegation doesn’t eliminate fiduciary responsibility.
Your First Fiduciary Duty Happens Before You Join
Many employers focus on what happens after they’re in the PEP.
The first fiduciary decision actually happens much earlier.
Selecting a PEP provider requires the same prudent process expected of any significant fiduciary decision.
Questions retirement plan committees should ask include:
- Why are we considering a PEP?
- Does this structure improve participant outcomes?
- How does this compare with remaining in a standalone plan?
- What services are actually included?
- Who is making discretionary decisions?
- How are fees structured?
- Who hired each service provider?
- How will conflicts of interest be managed?
The goal isn’t simply choosing a PEP.
The goal is demonstrating that joining this particular PEP was a prudent decision based on the information available at the time.
That documentation becomes part of your fiduciary process.
Read the Contract—Not Just the Proposal
This may be the single most important takeaway for retirement plan committees.
Proposals are marketing documents.
Contracts allocate ERISA fiduciary responsibilities.
We’ve seen situations where employers assumed certain fiduciary responsibilities had been transferred, only to discover later that the governing agreement placed those obligations squarely back on the employer.
Every committee should understand:
- Who is the named fiduciary?
- Who has discretionary authority?
- Which responsibilities remain with the employer?
- Who hires and monitors service providers?
- What happens if the employer decides to leave the PEP?
If your committee cannot explain how those responsibilities are divided, it will be difficult to defend that process later.
What Responsibilities Usually Stay With the Employer?
Every PEP is different, but employers commonly retain several important fiduciary responsibilities.
Selecting the Pooled Plan Provider
The decision to join a PEP belongs to the employer.
That means the employer is responsible for evaluating available options and documenting why one arrangement was chosen over another.
Simply accepting a recommendation isn’t enough.
Committees should understand why the chosen structure serves participants’ best interests.
Our ERISA Fiduciary Checklist can help committees evaluate whether they’re documenting key fiduciary decisions consistently.
Monitoring the PEP
Delegation doesn’t eliminate oversight.
Even after joining a PEP, employers should continue asking questions such as:
- Are services being delivered as expected?
- Are participants receiving appropriate support?
- Are investments being monitored?
- Are fees still reasonable?
- Have service levels changed?
Monitoring doesn’t require recreating the work already being performed by the Pooled Plan Provider.
It does require paying attention.
At Fiduciary Wise, we’ve worked with employers evaluating both standalone plans and Pooled Employer Plans, and one of the most common misconceptions we encounter is that joining a PEP eliminates the need for ongoing governance. In reality, the strongest committees continue asking questions—they simply ask different ones.
Providing Accurate Employee Data
Many PEPs rely on payroll integration.
That automation helps improve efficiency, but it doesn’t eliminate responsibility.
Employers still need to ensure payroll information is accurate, including:
- Employee eligibility
- Compensation
- Employment status
- Deferral elections
- Payroll changes
Automation is only as reliable as the information feeding it.
Timely Deposit of Contributions
Even in highly automated environments, employers remain responsible for ensuring employee deferrals are deposited timely.
Payroll integration reduces manual work.
It does not remove fiduciary accountability.
Monitoring Service Quality
Many employers assume someone else is evaluating the service providers.
Sometimes that’s true.
Sometimes it isn’t.
Committees should periodically ask:
- Are participant issues being resolved?
- Are service requests handled promptly?
- Are promised deliverables actually being delivered?
- Has service quality improved or declined?
Good governance includes verifying—not simply assuming—that services remain appropriate.
Monitoring Doesn’t Mean Micromanaging
Some committees worry that monitoring a PEP means reviewing every investment decision or operational process.
It doesn’t.
Think about hiring a general contractor to remodel your home.
You don’t expect to supervise every plumber, electrician, and roofer.
But you probably aren’t disappearing for six months either.
You still:
- Check progress
- Ask questions
- Review milestones
- Raise concerns
- Confirm work is being completed
The same principle applies to retirement plans.
Delegating work doesn’t eliminate oversight.
Watch for False Confidence
One of the biggest fiduciary risks isn’t poor administration.
It’s becoming too comfortable.
We’ve seen employers gradually stop asking questions because the plan appears to be running smoothly.
Committee meetings become shorter.
Reports receive less discussion.
Benchmarking becomes less frequent.
Documentation becomes lighter.
None of those changes happen overnight.
They happen slowly.
That’s often where the fiduciary red line begins.
Red Flags Every Committee Should Notice
Even within a PEP, certain warning signs deserve attention.
For example:
- You haven’t reviewed fees in years.
- Nobody can explain who monitors service providers.
- Participant complaints continue without resolution.
- Committee meetings no longer discuss retirement plan governance.
- Nobody knows what responsibilities remain with the employer.
- Reports are received but never reviewed.
- Decisions aren’t documented.
None of these automatically indicate a fiduciary breach.
But they should prompt discussion.
What Should a Retirement Plan Committee Review Each Year?
Annual reviews don’t have to be complicated. Many committees find it helpful to create an annual fiduciary calendar to ensure reviews happen consistently throughout the year.
A practical governance discussion might include questions like:
Is the PEP still meeting our organization’s needs?
Business goals change.
Workforces change.
Retirement plans should evolve as well.
Are fees still reasonable?
Benchmarking remains an important part of fiduciary oversight.
Even when another fiduciary is performing much of the work, committees should understand whether plan costs remain appropriate.
Are participants benefiting?
Ultimately, retirement plans exist to serve participants.
Ask questions such as:
- Are participation rates improving?
- Are employees engaging with educational resources?
- Are distributions being processed efficiently?
- Are participant concerns being addressed?
Good governance always comes back to participant outcomes.
Are we receiving meaningful reporting?
Committees should receive enough information to understand how the plan is performing.
That may include:
- Fiduciary reports
- Investment summaries
- Benchmarking analyses
- Service updates
- Operational metrics
Reports aren’t valuable if nobody discusses them.
A PEP Makes Governance Easier—Not Optional
One of the greatest advantages of a PEP is reducing complexity.
Committees spend less time managing vendors, coordinating service providers, and overseeing day-to-day administration.
That’s exactly what many organizations need.
But reducing work is different from eliminating governance.
ERISA still expects fiduciaries to exercise prudence.
Prudence requires process.
And process requires oversight.
The Right Question Isn’t “Can We Outsource?”
A better question is:
“How do we continue fulfilling our fiduciary responsibilities after we outsource?”
That’s the mindset that separates effective retirement plan governance from simple delegation.
Strong fiduciaries understand that outsourcing isn’t about doing less.
It’s about ensuring the right people are responsible for the right decisions while maintaining an appropriate level of oversight.
The Bottom Line
Joining a Pooled Employer Plan can be an excellent fiduciary decision. If you’re evaluating whether a PEP is right for your organization—or simply want a second opinion on your current arrangement—you can schedule a conversation with Fiduciary Wise.
For many employers, it reduces administrative complexity, strengthens governance, and provides access to expertise that would be difficult to build internally.
But no retirement plan committee should assume that joining a PEP ends its fiduciary responsibilities.
It changes them.
The employers that benefit most from a PEP aren’t the ones who stop paying attention.
They’re the ones who understand exactly what they’ve delegated, what they’ve retained, and how they’ll continue monitoring the arrangement year after year.
That’s where prudent governance lives—and where committees stay on the right side of the fiduciary red line.
Frequently Asked Questions
Google loves FAQ content.
Can employers completely eliminate fiduciary liability by joining a PEP?
No. Employers can delegate many responsibilities, but they still retain important fiduciary duties, including selecting and monitoring the Pooled Plan Provider and ensuring the arrangement continues serving participants’ best interests.
Who is responsible for monitoring a Pooled Employer Plan?
The Pooled Plan Provider performs many fiduciary functions, but employers still have an ongoing responsibility to prudently monitor the provider and document that oversight.
How often should a retirement plan committee review its PEP?
Most committees should formally evaluate their PEP at least annually, including reviewing fees, service quality, participant outcomes, and whether the arrangement continues to meet the organization’s needs.
What should employers review before joining a PEP?
Committees should carefully review the governing agreements, understand which fiduciary responsibilities are delegated versus retained, evaluate fees and services, and document the decision-making process.
