I have a 401(k) plan which utilizes a safe harbor matching contribution. Prior to 1/1/2018, the eligibility for all contribution sources was date of hire. The plan's entry dates prior to 1/1/2018 were date of hire. Highly compensated employees are excluded from receiving a safe harbor matching contribution.
Effective 1/1/2018, the eligibility for safe harbor match was amended to 1 Year of Service. The entry dates were amended to 1/1 and 7/1.
Unfortunately, it has been discovered the client has continued to use date of hire for eligibility and entry date purposes for the safe harbor matching contribution.
My question, can an amendment be done now to take the safe harbor matching contribution eligibility back to date of hire and the entry date back to date of hire for 2018? For 2019, the plan would move forward with the 1 Year of Service requirement and dual entry dates.
The plan does have a discretionary profit sharing contribution component. The eligibility is date of hire and the entry date is date of hire. Vesting is 100% immediate for all contribution types. The ineligible safe harbor matching contributions could be characterized.
Any thoughts would be appreciated.
Thank you.
