Regulators submitted a proposal to implement sweeping changes to the forms and regulations that govern annual employee benefit plan reporting on Form 5500. Form 5500 is the primary source of information about the operation, funding, assets and investments of these plans. Regulators are increasingly relying on the Form 5500 as a key component of their enforcement efforts. On July 21, 2016, the Department of Labor (DOL), Internal Revenue Service (IRS) and the Pension Benefit Guaranty Corporation (PBGC) published proposed reporting updates for employee benefit plans subject to the Employee Retirement Income Security Act of 1974 (ERISA). The extent of the changes is under debate.
