My initial impression was that a mid-year increase of matching contributions would cause the plan to no longer comply with the safe harbor requirements for that plan, instead necessitating that the plan be subject to ADP / ACP testing. However, upon closer inspection (and following discussion with legal counsel), the ramifications might be even worse. Treas. Reg. 1.401(k)-3(e)(1)(2nd sentence) states:
In addition, except as provided in paragraph (g) of this section, a plan which includes provisions that satisfy the rules of this section will not satisfy the requirements of § 1.401(k)-1(b) if it is amended to change such provisions for that plan year.
In other words, if one amends the plan to change the provisions of the plan that satisfy the safe harbor rules effective for that plan year and if the change is an increase, not a suspension or reduction of the match permitted by 1.401(k)-3(g), then the ADP test is not satisfied.
I had read the preambles to both the proposed and final versions of the 401(k) / 401(m) regulations and do not see anything that addresses mid-plan year increases in matching contributions. I also found nothing relevant in recent IRS gray books. We can't avoid dealing with the regulations as they are written.
Help me decide between two possible interpretations:
(1) Employer cannot increase the matching contribution in the middle of the plan year. There are some other possible solutions described below.
(2) Amend the plan to add in the additional layer of match (50% on deferrals in excess of 3% of pay but not exceeding 5% of pay) but don't amend any of the plan provisions describing the safe harbor match already in the plan. Now, the sentence in the regulation I quoted doesn't apply, right? [Query: might this interpretation go too far? Does the plan still meet the safe harbor rules so that ADP / ACP testing isn't required? Although it would be prudent to notify employees, is that technically required?]
Other work-around solutions:
- Wait until the beginning of the next plan year obviously.
- Change the plan year in compliance with the rules in the safe harbor portions of the 401(k) / 401(m) regulations.
- If one anticipates this happening in advance, use the discretionary match rules in the safe harbor portions of the 401(k) / 401(m) regulations, although to avoid having a higher rate of match available to an HCE than is available to any NHCE, the discretionary match probably has to be made for the whole plan year or exclude HCEs from the discretionary match.
FYI, I searched and found some prior threads on related topics, but none that addressed my question exactly:
