Forfeitures are one of those things in a 401(k) plan that everyone thinks they understand—until they don’t. It’s a small line item, often buried in reports, but it has a way of creating outsized problems when it’s ignored.
Most providers treat forfeitures like an administrative afterthought. They sit there, they accumulate, and eventually someone decides what to do with them. Reduce employer contributions, pay plan expenses, maybe allocate them. Simple enough, right? Except it isn’t.
The issue isn’t what forfeitures are—it’s how they’re used and when. I’ve seen plans carry large forfeiture balances for years with no clear policy. I’ve seen inconsistent application from year to year. I’ve seen providers who don’t raise the issue at all unless the auditor does. That’s not administration—that’s negligence dressed up as routine.
From a fiduciary standpoint, inconsistency is where the trouble begins. If the plan document allows multiple uses, that doesn’t mean anything goes. There needs to be a process, a rationale, and documentation to support it. Otherwise, you’re opening the door to questions you don’t want to answer.
Good providers don’t wait for forfeitures to become a problem. They track them, they communicate about them, and they push plan sponsors to make decisions in real time—not three years later when the number gets uncomfortable.
It’s not a complicated issue. But like most problems in this space, it becomes complicated the moment you stop paying attention.
