The 401(k) plan is aggregated with a DB plan for meeting the coverage test. The 401(k) is safe harbor match and NHCEs get an additional 7.5% contribution to satisfy the minimum gateway for testing the DB and DC plans together.
Question: Can the 401(k) plan amend the safe harbor formula mid-year to become a 3% nonelective and then make a 4.5% additional contribution to satisfy the gateway? I think it would be OK to do this as of the beginning of a plan year, but I am uncertain about whether it can be done mid-year.
Thank you!
