Left in 2013, 2021? Worth asking about employer money

  • In plan year 2013, 113 people (27% of active participants) left before they were fully vested. Turnover that high can count as a partial plan termination (Revenue Ruling 2007-43), which requires full vesting of employer money for those who left. The plan may argue it was routine turnover. Filing
  • In plan year 2021, active participants fell from 871 to 656 (25%), and 172 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.
