Plan Amendment

A Plan Amendment, in the context of an employer-sponsored 401(k) retirement plan, refers to any modification or change made to the plan's provisions or features. These amendments can be made by the plan sponsor, which is typically the employer, and are governed by the regulations set forth by the Employee Retirement Income Security Act (ERISA) and the Internal Revenue Service (IRS). The primary purpose of a plan amendment is to enhance or adjust the retirement plan's terms, benefits, or operational aspects to better suit the needs of both the employer and plan participants.

 

Examples of Plan Amendments:

 

  • Contribution Structure Modification: An employer may choose to implement a plan amendment to change the contribution structure of the 401(k) plan. For instance, they might decide to increase the employer match percentage or alter the employee contribution limits.

  • Vesting Schedule Adjustment: In certain cases, an employer might choose to amend the vesting schedule of the 401(k) plan. This amendment could alter the timeline that determines when employees become fully entitled to employer contributions.

 

  • Investment Options Update: A plan amendment can also involve updating the investment options available within the 401(k) plan. Employers might add or remove investment choices to provide participants with a more diverse and suitable range of investment opportunities.

 

It is crucial for employers to communicate plan amendments effectively to all plan participants, ensuring transparency and understanding of the changes. Additionally, the employer must comply with all legal requirements and provide sufficient notice to employees about the upcoming amendments to maintain compliance with applicable laws and regulations.

According to Mployer Insights’ 2026 analysis of 76,000+ employer benefit plans, basic group life insurance achieves near-universal participation with an 83% employer offer rate and a 97% employee enrollment rate, driven by the fact that 96% of basic plans are noncontributory (100% employer-paid). While 47% of employers structure life insurance as a variable multiple of earnings—with 1x salary serving as the dominant national standard (62% of multiple-based plans)—flat-dollar benefit options vary widely from $8,500 (10th percentile) to $48,793 (90th percentile). Additionally, 92% of employers offer employee-paid voluntary life insurance to allow workers to bridge the gap toward the recommended 10–12x salary coverage target.
