Left in 2025? Worth asking about employer money
- In plan year 2025, active participants fell from 969 to 760 (22%), and 118 people left before they were fully vested. When a plan loses about 20% or more of its participants in a year, the IRS presumes a partial plan termination (Revenue Ruling 2007-43). Everyone who left in that period must then be fully vested in the employer's contributions. Filing
This is a reason to ask the plan, not a finding. The plan decides, and it may show the drop was routine.
