Multiple-employer defined contribution pension plans to report aggregate account balance information by employer

Does anyone have any idea about the following change?

'' Defined Contribution Multiple-Employer Pension Plans: The instructions have been revised to implement an amendment to ERISA section 103(g) in the Setting Every Community Up for Retirement Enhancement Act of 2019 by requiring multiple-employer defined contribution pension plans to report aggregate account balance information by employer on the existing Form 5500/Form 5500-SF attachment for reporting participating employer information.

Thanks for your insights.

Form 5500 and 5500-SF have required, for a number of years now, an attachment when filing as a DC multiple-employer plan. For years before 2021, the attachment was required to list each participating employer in the MEP, the employer's EIN, and the percentage of the total contributions for that employer. Starting in 2021, the attachment now requires a fourth data element, which is the aggregate account balance attributable to each employer in the MEP.

See the 2021 Form 5500/5500-SF instructions under Line A – Box for Multiple-Employer Plan for more information (and compare to 2020).
