Filing and Notice Deadlines for Qualified Retirement and Health and Welfare Plans


Author, Ryan Gorman, Atlanta, +1 404 572 4609,

Employers and plan sponsors must comply with numerous filing and notice deadlines for their retirement and health and welfare plans. Failure to comply with these deadlines can result in costly penalties and excise taxes.  To avoid such penalties and excise taxes, employers must remain informed with respect to the filing and notice deadlines associated with their plans.

The filing and notice deadline table below provides key filing and notice deadlines common to calendar year plans for the next two months. Please note that the deadlines will be different if your plan year is not the calendar year. Please also note that the table does not include all applicable filing and notice deadlines, just the most common ones. King & Spalding is happy to assist you with any questions you may have regarding compliance with the filing and notice requirements for your employee benefit plans.
