Description: This article discusses adjusting IRC 415 limits for prior distributions. The proposed IRC 415 regulations issued last May contained guidance regarding how to adjust the benefit limits for prior distributions. This is commendable on the part of the IRS. How to adjust the IRC 415 limits for prior distributions has long been a source of confusion even for experienced pension actuaries. The best methodology is not immediately clear, and some methods have become common practice even if they can lead to inconsistent or unreasonable results.
