For mid-sized employers, changing a 401(k) provider is a decision that requires careful consideration. In today’s retirement plan market, with more than 710,000 401(k) plans and notable fee disparities between small and large plans, employers are under increasing pressure to evaluate providers for cost, compliance, service quality, and responding to new regulatory requirements like the SECURE 2.0 Act.

A 2023 survey found that 40% of advisors expect significant growth in the small plan 401(k) market, highlighting ongoing activity and potential for provider changes. For additional guidance on all aspects of plan administration, visit our 401(k) resources.

The stakes are high: uninterrupted 401(k) support continuity protects compliance and employee trust during any transition. Here’s how HR and Finance teams can proactively plan for continuity and minimize risk during a provider change.

The Short Answer: Four Essentials for 401(k) Support Continuity

When planning a 401(k) provider transition, employers should focus on four core areas:

• Audit your current support model: Evaluate who currently handles employer and participant questions, compliance, and issues. Avoid switching providers solely based on cost, as that can often lead to unforeseen challenges.

• Document what matters: Clearly record responsibilities, contacts, and escalation paths.

• Create escalation paths: Define how urgent issues are handled and who owns each step.

• Set review triggers: Identify the red flags that should prompt a provider or support model review.

Industry best practices emphasize that regular internal assessments and benchmarking are essential for achieving optimal outcomes during provider transitions (J.P. Morgan, 2025).

What to Verify About Your Support Model (Today)

It’s a question nearly every HR or Finance team faces: What should we confirm about our current 401(k) support structure before considering changes?

The real answer is often not what most expect. Employers must verify:

• Who answers employer administrative questions? Is it an in-house team or the provider?

• Who handles participant questions? Are employees routed to dedicated support or general hotlines?

• Who owns compliance tasks and filings? Is accountability clear, or are there gaps between roles?

• Where does the escalation path live? Is there a documented process for urgent issues, and is it clear who takes ownership at each step?

Industry guidance advises that employers should thoroughly assess the new provider’s support structure, including response times, escalation procedures, and the availability of dedicated account managers (J.P. Morgan, 2025).

Build a Continuity Plan: Owners and Artifacts

A clear continuity plan helps make every responsibility transparent during a 401(k) provider transition.

How to Build Your Plan:

1. Create a support map: List roles, contacts, and points of handoff for all key support functions.

2. Define response expectations: Clarify which issues are urgent versus routine, and set target response times.

3. Use an issue log template: Track issues by category, impact, owner, and resolution status.

4. Establish an escalation ladder: Document escalation steps and decision-makers for complex or urgent problems. Incomplete or outdated documentation is a top compliance red flag during transitions.

Case studies cited by J.P. Morgan highlight that assigning a dedicated transition manager and holding weekly meetings with both providers can help complete transitions on time and avoid service disruptions (J.P. Morgan, 2025).

Operational Areas to Audit: Your 401(k) Checklist

A successful transition depends on auditing key operational areas to prevent errors and compliance risks.

Key Areas to Audit:

• Payroll mapping: Validate integration and data flow between payroll and the new recordkeeper. Increasingly, this includes evaluating cybersecurity practices and technology integration to protect plan data.

• Contribution tracking: Confirm that deductions and deposits are accurate during and after the transition.

• Eligibility and distributions/loans: Confirm participant eligibility and loan/distribution processes are migrated correctly.

• Required notices and reporting: Verify blackout period notifications and compliance filings are handled on time.

EisnerAmper recommends testing payroll integration and verifying data accuracy to prevent errors during the transition (EisnerAmper, 2025).

Triggers That Justify a Provider Review

Too many employers ignore the warning signs that signal a need for a provider review, until it’s too late.

Key takeaway: Common triggers include persistent service issues, high or rising fees, outdated investment options, or lack of technological capability. Other factors like mergers, acquisitions, and rapid organizational growth can also warrant a fresh provider evaluation. Regulatory changes, such as the SECURE 2.0 Act, can also prompt a review (Charles Schwab Pressroom, 2024).

Employers should regularly assess whether their provider still fits their organization’s needs.

If You Decide to Switch: High-Level Steps

Switching 401(k) providers can be complex, but a clear plan helps avoid compliance pitfalls.

Key Steps:

1. Develop a transition timeline and assign roles.

2. Notify employees of the upcoming blackout period at least 30 days, but not more than 60 days, in advance.

3. Coordinate data transfer and test system integrations. Employers may benefit from leveraging automated tools or support from third-party administrators to help maintain accuracy.

4. Communicate with employees about new features, actions required, and support channels.

5. Monitor post-transition for errors and feedback.

Industry experts emphasize providing timely blackout notifications and clear employee communications to avoid confusion (J.P. Morgan, 2025).

Next Steps for Employers

Plan ahead. Regularly review your provider, document support structures, and create clear escalation paths. If you’re considering a change, start with an audit and a documented plan, your team and employees will thank you.

Schedule ongoing plan document reviews to stay compliant with regulatory changes.
