401(k) Fiduciary Responsibilities: A Spring Cleaning Checklist for Plan Sponsors

By Chris Johnson

Maybe you’re a bit behind on your spring cleaning at home? Spring is a natural time to review what’s working, refresh what isn’t, and prepare for the months ahead. For employers who offer a retirement plan, it can also be an ideal opportunity to revisit core 401(k) fiduciary responsibilities and confirm that plan oversight practices remain current and well-documented.

Fiduciary oversight is an ongoing process, not a one-time event. Taking time each year to review plan operations, investments, fees, and participant engagement can help plan sponsors support employees’ retirement readiness while maintaining strong governance practices.

Quick Checklist: Spring Clean Your 401(k)

Use this high‑level 401(k) fiduciary checklist to guide an annual plan review:

☐ Review the plan’s investment lineup and benchmarks

☐ Assess participant participation and savings trends

☐ Ensure fiduciary review activities are documented

Each item represents a broader area of fiduciary oversight that deserves periodic attention.

Review of the Plan’s Investment Lineup

Monitoring plan investments is one of a fiduciary’s core responsibilities. Plan sponsors often review the investment lineup to confirm that options available to participants remain consistent with the plan’s established investment framework.

A typical review may include:

  • Comparing investment performance against relevant benchmarks
  • Reviewing expense ratios and investment characteristics
  • Confirming consistency with stated investment objectives

Target-date strategies are commonly reviewed with particular care, especially when they serve as the plan’s default investment option.

Evaluate Plan Fees and Service Arrangements

Understanding how plan fees relate to services provided is another important component of fiduciary oversight. Periodic review of plan costs, such as recordkeeping, administrative services, and investment‑related fees, can help plan sponsors remain informed about how their plan compares with others of similar size and complexity.

This process may involve:

  • Reviewing required fee disclosures
  • Examining service provider agreements
  • Considering available fee benchmarking information

Maintaining awareness of plan expenses supports transparency and sound governance.

Confirm Plan Documentation and Operational Alignment

Retirement plans are governed by formal documents that describe how the plan is intended to operate. Periodic review helps sponsors confirm that plan operations remain aligned with those written provisions.

Key considerations often include:

  • Verifying required document updates have been completed
  • Confirming plan operations align with documented terms
  • Reviewing participant communications for accuracy and timeliness

Consistency between documentation and operation is an important aspect of plan oversight.

Assess Participant Engagement and Savings Trends

Participant behavior plays a meaningful role in retirement outcomes. Reviewing plan‑level data can help sponsors understand how employees are engaging with the plan.

Common metrics reviewed include:

  • Participation rates
  • Contribution levels
  • Loan or hardship withdrawal activity

When engagement trends suggest opportunities for improvement, sponsors may consider additional education tools, communication strategies, or plan design features to support participant understanding.

Maintain Fiduciary Oversight Documentation

Documenting fiduciary activities is an important part of a well‑structured governance process. Records of investment reviews, fee evaluations, and service-provider discussions help demonstrate thoughtful, consistent oversight.

Clear documentation also supports continuity as committee members, roles, or vendors change over time.
