Based on new inflation readings, the IRS and the Social Security Administration have released their 2023 cost-of-living adjustment values for tax-qualified retirement plans and Social Security benefits. The Pension Benefit Guaranty Corporation also published its 2023 single-employer and multiemployer defined benefit pension plan premium rates. The new IRS limits represent the highest annual increase in both dollars and percentage—a key change as we compare next year’s values with those from 2022 and 2021.
