401(k) Compliance Check #4: Required Participant Notices


In last month’s 401(k) Compliance Check, we discussed what to do if you inadvertently failed to enroll someone in your 401(k) plan. In this month’s Compliance Check, we focus on the variety of typical notices that are required for 401(k) retirement plans. We do not discuss every single notice, however; for example, we don’t discuss certain individualized notices, such as notices about whether a qualified domestic relations order is acceptable to the plan, nor the requirements to distribute summary plan descriptions or summary annual reports.

Why is This Topic Important?

Failing to provide required notices can subject the plan, and its fiduciaries, to liability. Notice failures can result in penalties imposed by the Internal Revenue Service or U.S. Department of Labor, or lawsuits from participants who were not informed about important information that affected their decision-making. For many safe harbor plans, providing the safe harbor notice is a pre-condition for qualifying for the safe harbor. And ensuring that all of your plan’s required notices have been timely provided makes for a smoother audit process, whether it be the plan audit for your Form 5500 or a governmental audit of your plan.

401(k) Safe Harbor Notice

Automatic Enrollment Notice (Non-QACA)
