along similar lines, Q and A #37 and #39 from the 2012 ASPPA Conference Q: A safe harbor 401(k) plan covers only salaried employees of Company X. The plan passes the ratio test under IRC §410(b). The plan year ends December 31. In June, X decides it would like to open up the 401(k) plan to the hourly paid employees, effective on July 1. Would this amendment be a violation of IRC §401(k)(12)? Proposed Answer
No. Although certain amendments to a safe harbor 401(k) plan are not permitted to be made effective on a date other than the first day of the plan year, this is not one of those types of amendments. The amendment solely applies to employees who are not otherwise covered by the plan. The safe harbor rules simply treats these individuals as newly eligible, and the safe harbor notice provided prior to the beginning of the plan year would not have had to be distributed to these employees before July 1. IRS Response: The IRS agrees with the proposed answer as long as there is no effect on the already-eligible employees. .............
Q: A safe harbor 401(k) plan fails the §410(b) coverage with respect to its profit sharing plan component. Within 9-1/2 months after the close of the plan year, the employer adopts a corrective amendment, pursuant to Treas. Reg. §1.401(a)(4)-11(g). Does this amendment cause the 401(k) component to lose its safe harbor for the plan year in which the corrective amendment is adopted?
Proposed Answer: No. Regardless of the position taken by the IRS with respect to amendments made to a safe harbor 401(k) plan, an implied exception exists for any amendments that are necessary to correct a violation of the nondiscrimination testing rules, which is a fundamental requirement for a qualified plan.
