Left in 2020? You may be owed employer money
- In plan year 2020, active participants fell from 227 to 180 (21%), and 35 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. A 2021 law (Consolidated Appropriations Act, section 209) can excuse a drop between March 2020 and March 2021 if the plan had rehired enough people by March 31, 2021. Filing
This is a reason to ask the plan, not a finding. The plan decides, and it may show the drop was routine.
