As the year comes to a close, employers face critical deadlines and responsibilities related to their 401(k) plans. From ensuring compliance to maximizing employee contributions, year-end planning is essential for both fiduciary protection and employee satisfaction.

Top 401(k) providers emphasize a proactive approach to year-end planning, helping employers navigate tasks efficiently and confidently. Here’s how the experts prepare companies for a smooth year-end.

Conduct a Comprehensive Plan Review

Check Contributions and Participation

Top providers start with a thorough review of employee and employer contributions:

  • Ensure employees are maximizing their deferrals within IRS limits

  • Confirm employer matching contributions are accurate

  • Identify employees who may need reminders or guidance

Reviewing contributions early helps avoid surprises and ensures employees can take full advantage of their retirement savings opportunities.

Evaluate Investment Options

Providers also review plan investment menus for performance and suitability:

  • Compare fund performance against benchmarks

  • Assess target-date funds and diversified options

  • Identify underperforming or high-fee investments

A well-reviewed investment lineup supports employees in meeting their retirement goals.

Ensure Compliance and Fiduciary Oversight

Conduct Year-End Testing

Compliance testing is a key focus at year-end. Top 401(k) providers guide employers through:

  • Nondiscrimination testing (ADP/ACP)

  • Top-heavy testing

  • Eligibility and coverage verifications

Early identification of potential compliance issues allows time for corrective action, reducing penalties and administrative headaches.

Maintain Proper Documentation

Providers emphasize maintaining thorough records of:

  • Investment committee decisions

  • Plan design updates

  • Employee communications

Proper documentation protects fiduciaries and demonstrates adherence to ERISA requirements.

Optimize Communication With Employees

Remind Employees About Contribution Limits

Employers often receive support from providers in communicating:

  • Maximum 401(k) deferral amounts

  • Catch-up contributions for those over 50

  • Deadlines for making adjustments before year-end

Clear communication ensures employees maximize their benefits and avoid missed opportunities.

Provide Education on Investments

Providers also help educate employees about:

  • Fund options and performance

  • Risk diversification

  • Resources like retirement calculators or one-on-one counseling

Education increases engagement and helps employees make informed decisions about their retirement.

Review Fees and Expenses

Examine Administrative and Investment Costs

High fees can reduce retirement savings over time. Top 401(k) providers help employers:

  • Compare recordkeeping and administrative fees to industry benchmarks

  • Review investment management costs

  • Explore opportunities for cost savings

This review ensures the plan remains cost-effective and aligns with fiduciary responsibilities.

Make Adjustments Before Year-End

If fees are high or services can be improved, providers advise on changes that can be implemented immediately, maximizing benefits for both employees and the company.

Plan Ahead for the Next Year

Consider Plan Design Changes

Providers encourage employers to assess:

  • Matching formulas

  • Profit-sharing contributions

  • Eligibility requirements

Making design changes at year-end ensures a smooth implementation for the next plan year.

Stay Informed About Regulatory Updates

Top providers keep employers updated on:

  • IRS contribution limits

  • DOL guidance

  • Plan design best practices

This proactive approach reduces risk and positions the plan for success in the coming year.
