A safe harbor match 401(k) plan currently has a six month eligibility (no hours per month requirement).
Due to some part time students who work on an as needed basis, the Employer would like to amend their plan to require 200 hours per month as part of their 6 month eligibility. They would like this amendment effective date 1/1/2019.
I believe the amendment is permissible, but only PROSPECTIVELY with a 30 day notice.
A coworker believes the amendment can be effective retroactively to 01/01/2019 because it will only apply to those hired on/after 01/01/2019.
I'd appreciate some input.
