We have a Plan that would like to remove the Auto Enroll provision EACA . None of the employees have ever been auto enrolled since they've always elected yes or no. The Plan year-end is 12/31. An Auto. Contribution Notice was provided in November of 2016 for the 2017 Plan Year. Can the Plan be amended to remove the EACA now or do we have to wait until November 2017 to make effective for January of 2018?
