Susan Muffley Act of 2025

This bill would restore full pension payments to certain Delphi retirees whose plans were cut when General Motors went bankrupt in 2009. The federal pension agency would recalculate monthly checks to the full amount workers earned and send back pay for past underpayments with 6% interest, with those back payments made within 180 days after the bill becomes law .

It also sets up a special Treasury fund to cover these costs and explains how taxes work on the back pay, letting most people spread the tax over three years unless they choose otherwise .

Key points

• Who is affected: People in these Delphi-related pension plans (and their beneficiaries), unless they were covered by a 1999 GM “top‑up” deal: Delphi Hourly-Rate Employees Pension Plan; Delphi Retirement Program for Salaried Employees; PHI Non‑Bargaining Retirement Plan; ASEC Manufacturing Retirement Program; PHI Bargaining Retirement Plan; Delphi Mechatronic Systems Retirement Program.
• What changes: Monthly benefits go up to the full amount earned under the plan. Past underpayments are paid back with 6% interest, and future checks are adjusted.
• How it’s paid for: A new “Delphi Full Vested Plan Benefit Trust Fund” in the U.S. Treasury will pay these benefits, with money provided as needed.
• Taxes on back pay: By default, the lump-sum back pay is taxed evenly over three years; there are special rules if the person dies and for surviving spouses who receive benefits.
• When: Back-pay lump sums must be issued within 180 days after the bill takes effect.
