The Plan was amended in mid-2015 to allow one employee to enter the Plan early. The employee was described as a newly employed employee and not a Highly -Compensated Employee. Now in 2016 it is discovered the new employee is a spouse of a Key Employee (they have different last names).. We need to correct as the new employee made 401k and received matching contributions during 2015. I believe this is a Demographic Failure requiring VCP, not SCP. Has anyone had a similar problem?
