A partial plan termination triggered by layoffs allowed a 61-year-old engineer to retain unvested 401(k) contributions, delaying Social Security claims.
A 61-year-old engineer retained tens of thousands in unvested 401(k) employer contributions after his wind-energy job was eliminated. The layoffs triggered an IRS partial plan termination, fully vesting affected employees in retirement funds they would have otherwise forfeited.
The engineer had expected to lose both his paycheck and unvested retirement contributions. Instead, the IRS rule allowed him to delay claiming Social Security, avoiding a 30% permanent reduction in benefits by waiting until age 67 or later. Benefits increase to roughly 124% of the full amount if claimed at age 70.
Traditional 401(k) withdrawals are taxable and may reduce Marketplace insurance subsidies before Medicare eligibility at 65, complicating retirement planning. The engineer’s case highlights how IRS rules can unexpectedly extend financial runways for older workers facing layoffs.
