    In general, Safe Harbor 401(k) plans automatically satisfy Top Heavy requirements. One exception is for plan years in which the employer makes discretionary contributions (such as profit sharing contributions) in addition to Safe Harbor contributions. Removing Safe Harbor contributions mid-year will also require plans be subject to all compliance testing.
