Reportable Events & Large Unpaid Contributions

Recent Changes to Reportable Events

On February 1, 2024, PBGC launched a new and improved e-Filing Portal. The new portal is used to prepare and submit certain documents and filings to PBGC, including reportable events. Key changes include a new, more secure, login process and a streamlined look and feel across all applications. For more information about how the revised login procedure affects PBGC’s e-Filing Portal, see Login.gov FAQs. The e-Filing Portal User Guide also contains useful information.

Overview

Section 4043 of ERISA requires that plan administrators and sponsors notify PBGC of the occurrence of certain events that may present a risk to a plan sponsor’s ability to continue a pension plan. PBGC's regulation on reportable events and large cumulative funding underpayments describes the events and notice requirements in detail (see 29 CFR Part 4043).

In most cases, reporting is due 30 days after the event occurs (i.e., "post-event" reporting). However, in certain cases involving nonpublic companies with large underfunding, advance notice of certain events must be given to PBGC (See 29 CFR §4043.61 for more information on advanced reporting).

Each event is listed below. For more information about an event, click on the applicable link below.

e-Filing Portal

PBGC's e-Filing Portal provides a secure application for submitting Form 10, Form 10-Advance and Form 200 information. The application will review filings and generate a list of omissions and inconsistencies prior to submission to ensure that filings are complete.

The web-based application walks the filer through various screens, prompting the filer to answer questions and enter required information. The application identifies whether a question needs to be answered based on the answers to previous questions and skips any unnecessary questions. The application allows filers to, among other things:

Save a partially completed filing;
Modify information any time prior to submission;
Pre-populate a filing with data from a previously submitted filing;
Route the filing as needed to facilitate e-certifications; and
Review prior filings submitted via the e-Filing Portal.

A user guide includes step-by-step instructions on how to create and manage your e-Filing Portal account.
