This document contains final revisions to the instructions for the Form 5500 Annual Return/Report of Employee Benefit Plan and Form 5500-SF Short Form Annual Return/Report of Small Employee Benefit Plan effective for plan years beginning on or after January 1, 2021. These final revisions to the instructions were included in a broader proposal of form and instruction changes published on September 15, 2021. The limited number of instruction changes in this document implement annual reporting changes for multiple-employer plans (including pooled employer plans) that result from statutory provisions in section 101 of the Setting Every Community Up for Retirement Enhancement Act of 2019 (SECURE Act). The other changes to the Form 5500 Annual Return/Report included in the September 2021 proposal will be the subject of one or more separate and later final notices.
