Running a 401(k) plan puts business owners and executives on the hook for ERISA fiduciary duties that carry real legal consequences. Pooled Employer Plans (PEPs) offer a structural solution by shifting many plan-level administrative and investment responsibilities to a professional Pooled Plan Provider (PPP) and other designated fiduciaries, leaving the employer with a narrower, more manageable set of obligations.
This article breaks down which fiduciary duties shift, which responsibilities remain with the Adopting Employer, and how to evaluate whether a PEP is the right move for your organization.
Key Takeaways
Pooled Employer Plans centralize many plan-level fiduciary duties with a professional Pooled Plan Provider and designated fiduciaries, reducing the day-to-day fiduciary burden an employer carries for its retirement plan. The PEP structure can shift responsibility for plan administration, investment management, compliance filings, and participant disclosures away from the Adopting Employer.
Adopting Employers still retain important responsibilities, including prudently selecting and monitoring the Pooled Plan Provider and providing accurate payroll and participant data. These responsibilities are substantially narrower than running a standalone plan in which the employer or an internal committee must oversee investments, administration, vendors, filings, and ongoing compliance.
The SECURE Act established Pooled Employer Plans in December 2019, allowing multiple unrelated employers to participate in a pooled retirement plan structure. This gave small and mid-sized businesses another way to access professional plan governance, investment fiduciary oversight, and compliance support.
Quintes and the Quintes 401(k) Pooled Employer Plan provide a useful example of how a well-structured PEP can reduce fiduciary risk and simplify plan administration. Quintes has provided retirement plan administration services since 1986 and now serves as the Pooled Plan Provider, named fiduciary, and plan administrator for the Quintes 401(k) PEP. The sections below explain which fiduciary duties shift to Quintes and other designated fiduciaries, what remains with each Adopting Employer, and how the structure can reduce employer burden.
Understanding Employer Fiduciary Liability Under ERISA
Under ERISA, anyone who exercises discretion over a retirement plan’s management, investments, or administration is a fiduciary. That often includes business owners, CFOs, HR directors, and members of internal plan committees. Under 29 USC § 1104(a), a fiduciary who breaches these duties can be held personally liable to restore any losses to the plan. This is not hypothetical: the Department of Labor’s Employee Benefits Security Administration (EBSA) actively investigates plan fiduciaries, and participant class actions have targeted prior litigation involving excessive fees, underperforming funds, and misuse of forfeitures.
The core fiduciary duties under ERISA include:
- Duty of loyalty: act solely in the financial interest of plan participants and beneficiaries, avoiding conflicts of interest
- Duty of prudence: use a careful, documented process when selecting and monitoring investments, plan providers, and other plan services
- Duty to diversify: spread the plan’s investments to reduce concentration risk
- Duty to follow plan documents: operate consistent with the written terms of the plan
- Duty of reasonableness on fees: ensure all the fees and expenses charged to the plan are reasonable relative to market alternatives
In a traditional single-employer 401(k), the employer is typically the plan sponsor and may also serve as the named fiduciary or appoint an internal committee. Even when outside providers perform certain functions, the employer retains responsibility for prudently selecting and monitoring those providers. A 2026 federal court ruling allowed a fiduciary breach claim to proceed against Illinois Tool Works for failure to monitor investment and recordkeeping fees, illustrating the legal exposure that can arise when fiduciary monitoring is challenged.
Pooled Employer Plans are designed to preserve ERISA protections for participants while shifting many operational and investment fiduciary duties away from the employer and to professional fiduciaries that specialize in retirement plan management.
What Is a Pooled Employer Plan and How Does It Work?
A Pooled Employer Plan is a 401(k) arrangement in which multiple unrelated employers participate under a pooled structure for ERISA purposes. Each Adopting Employer executes its own adoption agreement and can select plan provisions that apply to its workforce, rather than being limited to a single set of employer-specific provisions.
The SECURE Act established PEPs for plan years beginning January 1, 2021. SECURE 2.0, passed in 2022, further expanded the framework, including eligibility for certain 403(b) arrangements and additional startup tax credit opportunities for qualifying small employers.
The Pooled Plan Provider is the entity designated to operate the PEP. The PPP serves as the named fiduciary, plan sponsor, and plan administrator and coordinates key providers such as the recordkeeper and designated 3(38) Investment Manager. In the Quintes 401(k) PEP, each Adopting Employer has its own adoption agreement and can choose significant plan design features, including matching formulas, vesting schedules, eligibility provisions, and automatic enrollment options. Quintes also provides hands-on plan design consulting to help employers select provisions that align with their goals and budget.
The PEP structure also helps isolate one Adopting Employer from the compliance failures of another, subject to the applicable PEP rules. This is an important distinction from older multiple-employer arrangements in which one employer’s failure could create broader plan-level consequences.
Accurate payroll integration is essential. The PEP structure relies on each Adopting Employer providing clean, timely payroll and participant data to the plan’s recordkeeping and administrative systems. Even a well-structured PEP depends on accurate employer-supplied information.
How Pooled Employer Plans Shift Key Fiduciary Duties
The main way Pooled Employer Plans reduce fiduciary liability is by allocating specific fiduciary roles to professional providers within the PEP structure. The Pooled Plan Provider assumes major plan-level responsibilities and coordinates the administrative and investment functions that would otherwise require substantial employer oversight.
Three major categories of responsibility typically shift:
- Plan administration (ERISA 3(16)): The 3(16) fiduciary handles functions such as eligibility determinations, participant notices, compliance testing, Form 5500 filings, and loan and distribution processing. In the Quintes 401(k) PEP, the Pooled Plan Provider performs these administrative functions, significantly reducing the Adopting Employer’s day-to-day administrative burden.
- Investment management (ERISA 3(38)): A designated 3(38) Investment Manager has discretionary authority to select, monitor, and replace plan investments. This shifts the investment-selection function away from the Adopting Employer while providing disciplined professional oversight of the investment lineup.
- Plan-level fiduciary governance: The Pooled Plan Provider serves as the named fiduciary and plan sponsor for the pooled arrangement and coordinates the recordkeeper, Investment Manager, and other plan-level functions. Clearly documenting these roles helps reduce ambiguity about which party is responsible for each fiduciary duty.
In a traditional single-employer 401(k), an HR leader, CFO, or internal committee may be responsible for many administrative and oversight decisions, even when outside vendors perform portions of the work. That creates fiduciary burden and potential exposure for duties the internal team may not have specialized expertise to manage.
By joining a PEP, an Adopting Employer’s fiduciary role narrows to a smaller set of decisions and ongoing responsibilities. The Pooled Plan Provider and designated fiduciaries take on much of the plan-level administration and investment oversight, while the employer focuses on prudent provider monitoring, accurate data, and its selected plan provisions.
Fiduciary Responsibilities in Traditional 401(k) vs PEP
Table 1 below compares who holds major fiduciary responsibilities in a traditional standalone 401(k) versus a Pooled Employer Plan. The comparison shows how the PEP structure can reduce direct employer fiduciary and administrative burden.
Fiduciary Responsibilities in a Traditional 401(k) vs. a Pooled Employer Plan
| Fiduciary Duty | Traditional Single-Employer 401(k): Primary Responsible Party | Pooled Employer Plan (PEP): Primary Responsible Party | Residual Role of Adopting Employer |
| Named fiduciary / plan governance | Employer or internal committee | Pooled Plan Provider | Prudently select and monitor the Pooled Plan Provider. |
| Investment menu selection and monitoring | Employer or investment committee | Designated 3(38) Investment Manager | Monitor the Pooled Plan Provider and review fiduciary reporting; the Adopting Employer does not select individual investments when discretion is assigned to the 3(38) Investment Manager. |
| Plan document maintenance | Employer, counsel, or TPA | Pooled Plan Provider maintains the PEP governing documents | Execute its own adoption agreement, select available plan provisions, and review changes affecting those provisions. |
| Form 5500 and audit coordination | Employer is responsible for arranging or delegating filings and audit work | Pooled Plan Provider coordinates filings and the pooled-plan audit | Provide accurate employer data and respond to information requests. |
| Participant disclosures | Employer is responsible for required notices and delivery processes | Pooled Plan Provider manages required plan-level disclosure processes | Maintain accurate workforce information and help ensure employees can access plan communications. |
| Payroll contribution remittance and eligibility data | Employer supplies payroll and participant data and transmits contributions | Adopting Employer, supported by the Pooled Plan Provider and recordkeeper | Provide accurate payroll files and timely contribution information. |
In a PEP, the Pooled Plan Provider assumes primary responsibility for many operational and plan-level fiduciary functions, while the Adopting Employer focuses on provider oversight, plan-design decisions available under its adoption agreement, and data quality. The sections below explain why those shifts matter.
How PEPs Reduce Employer Exposure to Fiduciary Liability
Fewer discretionary plan-level decisions by the employer mean fewer opportunities for an ERISA breach to arise from the employer’s own actions. A PEP can shift responsibility for investment selection, compliance filings, and participant disclosures to the Pooled Plan Provider and designated fiduciaries, reducing the Adopting Employer’s direct exposure associated with those functions.
Centralizing investment selection with a 3(38) Investment Manager reduces the employer’s direct responsibility for selecting and replacing individual investment options. Professional investment oversight can also provide a disciplined process for fund selection, monitoring, benchmarking, and documentation.
Having a professional 3(16) administrative fiduciary inside the Pooled Employer Plan can reduce risk around eligibility errors, disclosure failures, loan and distribution processing, and other administrative functions. Standardized processes and specialized expertise can be difficult for a small internal HR team to replicate.
Recent years have seen continued scrutiny of plan fees and investment oversight. By the end of 2024, PEPs had accumulated more than $20 billion in assets across roughly 51,000 Adopting Employers and 1.6 million participants. That growing scale can strengthen negotiating leverage and support more institutionalized administrative and investment processes.
Employers cannot eliminate fiduciary liability entirely, but they can materially narrow its scope. In a PEP, the Adopting Employer’s ongoing fiduciary responsibilities primarily center on prudently selecting and monitoring the Pooled Plan Provider, providing accurate data, and fulfilling any responsibilities specifically reserved to the employer in the plan documents.
What Responsibilities Employers Still Retain in a PEP
Pooled Employer Plans reduce but do not erase fiduciary responsibilities. Understanding what remains with the Adopting Employer is essential to maintaining a prudent process after joining the plan.
- Prudent selection of the Pooled Plan Provider: An Adopting Employer should assess the PPP’s qualifications, experience, fee structure, conflicts, service model, and scope of fiduciary responsibility. The employer should document why it selected the provider and the information considered during that process.
- Ongoing monitoring: The Adopting Employer remains responsible for monitoring the Pooled Plan Provider. That can include reviewing service reports, fees, audit findings, fiduciary reporting, and performance against the provider’s stated responsibilities. If material concerns arise, the employer should evaluate and document an appropriate response.
- Accurate payroll and eligibility data: Adopting Employers remain responsible for providing accurate payroll, hire dates, compensation data, hours worked, and other information needed to administer the plan correctly. The Pooled Plan Provider and recordkeeper depend on that information to perform their responsibilities.
- Employee communication and enrollment support: The Quintes 401(k) PEP includes robust participant education services and plan communications. The Adopting Employer still needs to make sure employees have access to the information and systems they need, and it may choose to supplement participant education with an Advisor if desired.
Employer Duties Before and After Joining a PEP
Table 2 shows how a typical business owner’s and HR team’s responsibilities change when moving from a standalone 401(k) to a Pooled Employer Plan such as the Quintes 401(k) PEP.
Employer Duties Before and After Joining a Pooled Employer Plan
| Task / Decision Area | Traditional Single-Employer Plan: Employer Role | In the Quintes 401(k) PEP: Adopting Employer Role |
| Drafting and updating plan documents | Employer hires counsel or a TPA and retains responsibility for plan-document decisions | Quintes maintains the PEP documents; each Adopting Employer has its own adoption agreement and selects available plan provisions. |
| Selecting and replacing investment options | Employer or committee selects and monitors investments | A designated 3(38) Investment Manager selects and monitors investments; the Adopting Employer monitors the Pooled Plan Provider. |
| Coordinating the annual audit | Employer arranges the audit, prepares records, and coordinates the process | Quintes coordinates the pooled-plan audit; the Adopting Employer provides requested employer data. |
| Handling plan corrections and restatements | Employer coordinates corrections with its providers and remains responsible for employer-level issues | Quintes manages plan-level correction and restatement processes; the Adopting Employer assists with data or employer-specific action when needed. |
| Interpreting plan provisions | Employer or committee works with its advisors to interpret plan terms | Quintes administers the PEP documents and the Adopting Employer’s adoption agreement, with plan design consulting available when provisions need to be reviewed. |
| Monitoring service providers | Employer monitors the recordkeeper, Investment Manager, and other providers | The Adopting Employer monitors Quintes as the Pooled Plan Provider; Quintes coordinates the recordkeeper, Investment Manager, and other plan-level providers. |
| Submitting accurate payroll files | Employer runs payroll and transmits data | Same core employer responsibility: the Adopting Employer runs payroll and provides timely, accurate data. |
The PEP shifts many tasks from hands-on employer execution to professional plan administration and higher-level employer oversight. Plan document maintenance, compliance filings, audit coordination, and investment management move largely to the Pooled Plan Provider and designated fiduciaries, while the Adopting Employer continues to choose its available plan provisions and remains responsible for accurate payroll and participant data.
Operational Benefits: Reducing Administrative and Compliance Burdens
Fiduciary risk and administrative workload are closely linked. Every missed deadline, late notice, or operational error can create a compliance problem and potentially increase fiduciary exposure. Joining a PEP centralizes many plan administration and operational functions with the Pooled Plan Provider, significantly reducing the internal time, expertise, and oversight required from business owners and HR teams.
Specific areas where a Pooled Employer Plan can streamline work include:
- Plan document maintenance and regulatory updates, while each Adopting Employer continues to select the provisions available under its own adoption agreement
- Form 5500 filing and audit coordination for the pooled plan
- Service provider coordination, including recordkeeping and investment management relationships
- Day-to-day operations such as loan processing, hardship distributions, and required minimum distributions
- Recordkeeping services and participant account maintenance
Standardized processes, automated data flows, and consolidated reporting inside a PEP can reduce employer-specific administrative errors. The DOL’s 2026 PEP Bulletin reflects a growing infrastructure of registered Pooled Plan Providers operating these arrangements.
Businesses with limited internal benefits staff often benefit most from this structure. Functions that might otherwise require substantial internal expertise can be handled by the Pooled Plan Provider’s experienced team, allowing the employer to focus on its business while maintaining a clearer, more manageable fiduciary role.
Key Risk Areas for Plan Sponsors and How PEPs Address Them
Table 3 maps common ERISA risk areas to the way a Pooled Employer Plan can address them. The emphasis is not on eliminating fiduciary responsibility, but on assigning specialized functions to professional fiduciaries and reducing the concentration of risk at the employer level.
Key ERISA Risk Areas and How a Pooled Employer Plan Addresses Them
| Risk Area | Risk in Traditional Employer Plan | How a Pooled Employer Plan Addresses the Risk |
| Investment underperformance or excessive fees | Employer committee is responsible for selecting and monitoring investments and may have less negotiating leverage at smaller scale | A designated 3(38) Investment Manager selects and monitors investments, while pooled scale can improve access to institutional-quality options and fee arrangements. |
| Late or incorrect participant contributions | Employer must manage payroll transmission and contribution timing; errors can create compliance and fiduciary concerns | The Pooled Plan Provider and recordkeeper can standardize payroll processes and monitor data, while the Adopting Employer remains responsible for timely and accurate payroll submissions. |
| Faulty eligibility tracking | Employer must interpret and administer eligibility provisions correctly | The Pooled Plan Provider administers eligibility using the provisions selected by each Adopting Employer in its adoption agreement. |
| Incomplete or late participant disclosures | Employer must manage required notice preparation and delivery | The Pooled Plan Provider manages required plan-level notice processes, while the Adopting Employer supports accurate employee data and access to communications. |
| Plan document not updated for law changes | Employer must coordinate updates with counsel or a TPA | The Pooled Plan Provider maintains and updates the PEP governing documents; each Adopting Employer reviews changes affecting its adoption agreement and selected provisions. |
Adopting Employers still need to do their part, especially around accurate payroll data, timely contribution remittance, and monitoring the Pooled Plan Provider. Even so, a well-governed Pooled Employer Plan can materially reduce the number of plan-level fiduciary functions the employer must perform directly.
Why Accurate Payroll and Participant Data Still Matter
Even in a well-structured Pooled Employer Plan, inaccurate or late payroll data can undermine plan administration. Adopting Employers must ensure timely remittance of employee contributions and accurate payroll data because errors can affect participant accounts and trigger corrective action.
Errors in compensation definitions, hours worked, or hire dates can lead to missed eligibility or incorrect employer contributions. These employer-supplied data responsibilities remain with the Adopting Employer after joining a PEP.
Best practices for maintaining accurate payroll for plan purposes include:
- Standardized data fields aligned with the Pooled Plan Provider’s requirements
- Automated contribution calculations tied to payroll cycles
- Timely submission schedules with clearly defined deadlines
- Regular reconciliation of payroll reports against plan records
Quintes uses standardized data templates, validation processes, and structured coordination with payroll providers to help Adopting Employers identify issues early. These practices can reduce administrative errors while making the employer’s remaining responsibilities clearer and easier to manage.
PEPs Versus Traditional Employer Plans on Liability and Governance
Table 4 focuses on fiduciary liability, governance complexity, and oversight obligations for employers evaluating retirement plan structures. It compares a traditional single-employer 401(k), a generic Pooled Employer Plan, and the Quintes 401(k) PEP.
Liability, Governance, and Plan Design Comparison
| Feature | Traditional Single-Employer Plan | Pooled Employer Plan (Generic) | Quintes 401(k) PEP |
| Named fiduciary responsibility | Employer executives or committee retain plan-level named fiduciary responsibilities unless appropriately delegated | Pooled Plan Provider holds the named fiduciary role | Quintes serves as Pooled Plan Provider, named fiduciary, plan sponsor, and plan administrator; its retirement plan administration experience dates to 1986. |
| Investment fiduciary (3(38)) support | Employer appoints and monitors an Investment Manager and retains responsibility for prudent selection and monitoring | Pooled Plan Provider coordinates or appoints the 3(38) Investment Manager | Quintes coordinates 3(38) investment management with documented selection, monitoring, and benchmarking processes aligned with institutional best practices. |
| Administrative fiduciary (3(16)) support | Employer or delegated provider performs administrative functions; employer retains oversight obligations | Pooled Plan Provider or delegated 3(16) fiduciary handles administration | Quintes performs comprehensive 3(16) administrative functions within its PEP structure. |
| Level of employer governance complexity | Higher; employer must coordinate multiple providers and governance functions | Reduced; Adopting Employer primarily monitors the Pooled Plan Provider | Reduced; Quintes centralizes plan-level governance, reporting, and compliance while the Adopting Employer monitors Quintes and fulfills payroll/data responsibilities. |
| Audit and Form 5500 oversight | Employer coordinates filings and audit work | Pooled Plan Provider coordinates filings for the pooled plan | Quintes manages Form 5500 filing, audit coordination, and regulatory reporting for the PEP. |
| Transparency of fees and service model | Employer must evaluate and benchmark multiple provider arrangements | Depends on the Pooled Plan Provider | Quintes emphasizes clear reporting and an understandable service model to support the Adopting Employer’s monitoring process. |
| Plan design flexibility | Employer has direct control over plan-design provisions | Varies by PEP and provider | Each Adopting Employer has its own adoption agreement and significant flexibility over features such as match, vesting, and eligibility; Quintes provides hands-on plan design consulting. |
A well-structured PEP can reduce fiduciary duties compared with a standalone plan. Quintes differentiates its approach through hands-on plan design consulting, clearly documented fiduciary responsibilities, institutional-style investment oversight, structured onboarding, and sophisticated plan administration backed by decades of experience.
- Hands-on plan design consulting: Quintes works with each Adopting Employer to align plan features with business goals and budget.
- Clearly documented fiduciary responsibilities: Each party’s role is mapped in writing to reduce ambiguity and clarify the employer’s remaining responsibilities.
- Investment oversight aligned with institutional best practices: Fund selection, monitoring, and benchmarking are handled through a disciplined professional process.
- Structured onboarding: Standardized documents, close coordination with payroll providers, and clear timelines are designed to minimize disruption. When a standalone 401(k) is merged into the Quintes 401(k) PEP, a realistic transition range is approximately 90 to 120 days, depending on recordkeeper cooperation, payroll complexity, and the employer’s internal capacity.
- Sophisticated and experienced plan administration: Quintes uses an administrative structure built on decades of retirement-plan experience to deliver a streamlined compliance solution.
Why Partner With Quintes for Your Pooled Employer Plan
Quintes has provided retirement plan administration services since 1986, building decades of experience in plan design, compliance, and day-to-day operations. As the sponsor of the Quintes 401(k) Pooled Employer Plan, Quintes serves as the Pooled Plan Provider, named fiduciary, and plan administrator. That experience is central to the value of the structure for employers that do not want to build the same level of retirement-plan expertise internally.
What sets Quintes apart is not simply the PEP structure, but the way the team defines, documents, and executes each responsibility for the Adopting Employer.
Quintes also emphasizes transparent, easy-to-understand fee structures and clear reporting, which support the Adopting Employer’s ongoing monitoring obligations. The goal is to give employers a retirement plan structure that reduces internal administrative effort and fiduciary complexity without requiring them to give up the plan design features that matter to their workforce and business goals.

Conclusion: Using Pooled Employer Plans to Manage Fiduciary Risk
Pooled Employer Plans are not about eliminating all fiduciary liability. They are about shifting significant plan-level responsibilities to professional fiduciaries that are better equipped to manage ERISA administration, investment oversight, and compliance at scale.
The practical shift for the Adopting Employer is from active plan-level administration and investment decision-making to focused oversight. The employer continues to select and monitor the Pooled Plan Provider, choose available plan provisions, and maintain accurate payroll and participant data, but it no longer has to perform many of the specialized fiduciary functions required in a standalone 401(k).
For many small and mid-sized organizations, particularly those without a dedicated benefits department, that reduction in administrative effort, internal expertise requirements, and oversight complexity can be one of the strongest reasons to consider a PEP.

Frequently Asked Questions
These FAQs address common questions employers have when deciding whether to move from a traditional single-employer 401(k) to a Pooled Employer Plan structure.
Does joining a pooled employer plan completely eliminate my fiduciary liability?
No. A Pooled Employer Plan does not eliminate all fiduciary liability. The Adopting Employer retains responsibility for prudently selecting and monitoring the Pooled Plan Provider and for providing accurate payroll and participant data. What changes is the scope of responsibility: many discretionary decisions about plan administration and investments move to professional fiduciaries inside the PEP, reducing the employer’s direct fiduciary burden.
How do PEPs affect my ability to customize plan design for my workforce?
The Quintes 401(k) PEP is designed to offer the same types of plan design features employers expect from an employer-sponsored 401(k), and each Adopting Employer has its own adoption agreement. Employers can choose significant features such as matching formulas, vesting schedules, eligibility provisions, and automatic enrollment options. Quintes provides hands-on plan design consulting to help each Adopting Employer select provisions that align with its specific goals and budget, so adopting the PEP does not require a significant loss of plan design flexibility.
What happens if I am not satisfied with my PEP provider in the future?
If an Adopting Employer decides to leave the Quintes 401(k) PEP, the transition is not necessarily more complex than terminating or transitioning a single-employer 401(k) plan. The steps depend on the employer’s chosen path and may include adopting a new arrangement, transferring assets, and coordinating participant communications. Reviewing the applicable transition provisions in advance and working with an experienced team can help keep the process orderly.
Are PEPs only suitable for very small employers, or do larger organizations benefit too?
Pooled Employer Plans can work for small, mid-sized, and larger organizations that want to simplify plan governance and reduce internal administrative workload. Growing companies, organizations with multiple entities, and employers going through corporate transactions may also benefit from a structure that centralizes plan-level fiduciary oversight while allowing each Adopting Employer to select plan provisions that fit its needs.
