Eligibility in a New Safe Harbor 401k Plan

[Pammie57]

Client set up a Safe harbor 401 (k) Plan effective 3/1/2019.  They initially wanted a 3 month eligibility with entry dates monthly-following.  Now we are in June, and they are wanting to amend their document to say only 60 days  wait - (to agree with the wait for health benefits with their company).  No one so far has been made to wait 3 months to start deferring.  Thoughts?? Any IRS problems that they could run into?

I believe expanding/liberalizing eligibility is one of the permissible mid-year amendments for safe harbor plans.
