Left in 2020, 2024? You may be owed employer money

  • In plan year 2020, active participants fell from 1,619 to 1,055 (35%), and 127 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
  • In plan year 2024, active participants fell from 1,208 to 966 (20%), and 72 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.
