General Motors Pension: What You Need to Know

The GM Salaried Retirement Program covers automotive workers with specific eligibility requirements based on years of service and, in some cases, collective bargaining agreements. Benefits vary significantly by hire date, plan tier, and whether you are in a union or management track.

Plan status: Frozen

GM operates separate pension plans for salaried and hourly (UAW) employees. The salaried plan uses a traditional defined benefit formula based on final average salary and years of service. Hourly employees receive a flat dollar monthly benefit per year of service negotiated in UAW contracts, currently around $56-$60 per month per year. GM froze the salaried plan for new participants in 2012.

Buyout history

GM executed a landmark $26 billion pension transfer in 2012, the largest in U.S. history, offering lump sums to 42,000 salaried retirees and annuitizing remaining obligations through Prudential. A second round targeted salaried non-retirees in 2013. These windows permanently reduced GM's pension liability and closed the plan to future lump sum elections.

Understanding your lump sum offer

If General Motors has offered you a lump sum, that number was calculated using the IRS 417(e) formula with the applicable segment rates for your plan year. The minimum lump sum the plan must offer is the present value of your accrued benefit discounted at those segment rates.

Plans can offer more than the minimum, but rarely do. If the lump sum offer is close to what this calculator produces using the current segment rates, the offer is actuarially fair. If it's significantly lower, it's worth asking your plan administrator which lookback month they used and confirming the mortality table.

For 2026 plan years, the segment rates from November 2025 are 5.03% for years 1-5, 5.35% for years 6-20, and 5.57% for years 21 and beyond. Compare these against the rates in your lump sum election notice, which should appear in the offer paperwork.

Tax considerations

The lump sum is taxable in the year you receive it unless you roll it directly to a traditional IRA or your new employer's 401(k). A direct rollover (plan to IRA) is not a taxable event. Taking the cash is. If you take cash, the plan is required to withhold 20% for federal taxes, and you'll owe the remaining taxes when you file.

A $400,000 lump sum taken as cash with $80,000 withheld still results in tax at ordinary income rates on the full $400,000. For most retirees in that range, the total federal and state tax bill on a cash distribution runs $100,000 to $140,000 in the year of receipt. The rollover avoids all of that until you take distributions later.

When the lump sum makes sense

For General Motors retirees specifically, the lump sum can make sense when: you have serious health concerns and don't expect to reach the break-even age, you have other guaranteed income sources (Social Security, spouse's pension) that cover your baseline expenses, or you're a disciplined investor comfortable managing a seven-figure portfolio.

The annuity is typically the right answer for people who don't have other guaranteed income, whose spouse is younger and may outlive them significantly, or who simply don't want to manage a large portfolio in retirement. The guaranteed payment doesn't fluctuate with markets. It shows up every month regardless of what the S&P did.
