The Required Amendments List is an annual list of changes in retirement plan qualification requirements (see Revenue Procedure 2016-37). It also establishes amendment deadlines for individually designed plans. Generally, the Required Amendments List will include an item after guidance for the item (including any model amendment) is issued. At the IRS’s discretion, however, the List may also include an item in other circumstances, such as when a statutory change is enacted and no additional guidance is anticipated. Plan amendment deadline The plan amendment deadline for most items on each list will be the end of the second calendar year following the year in which the list is issued unless noted otherwise.

See New Determination Program Rev. Proc. 2016-37 for a summary of this change. However, the IRS intends to publish cumulative lists for pre-approved plans submitted for an opinion or advisory letter.
