A Form 5500 is used to report information regarding certain ERISA plans. For purposes of health and welfare plans, when participation is 100 or more participants on the 1st day of the plan year, the employer is required to complete and file the Form 5500 by the last day of the seventh month following the end of the plan year.
An employer can file for a one time 2.5 month extension to file Form 5500, Form 5500-SF, Form 5500-EZ, and/or Form 8955-SSA by completing and filing Form 5558 on or before the normal due date, which for health and welfare plans is the last day of the seventh month following the end of the plan year. These extensions will automatically be approved if filed timely.
Note: If the filing date falls on a Saturday, Sunday, or a legal holiday, the return may be filed on the next day that is not a Saturday, Sunday, or a legal holiday
