NUA lump-sum distribution treatment with §404(k) dividends

Quick answer: No — based on the documents provided, § 404(k) cash dividends paid on employer stock held in a 401(k) are treated as a separate contract distribution under a special statutory carve-out, so they do not count toward, and do not disqualify, a later distribution of the participant's remaining account balance as a "lump-sum distribution" under IRC § 402(e)(4)(D). This answer assumes 2025 tax-year rules; the regulation supporting this analysis is decades old and should be confirmed still valid.

What the lump-sum rule requires

IRC § 402(e)(4)(D)(i) defines a lump-sum distribution as "the distribution or payment within one taxable year of the recipient of the balance to the credit of an employee which becomes payable to the recipient" on account of death, attaining age 59½, separation from service, or disability, from a qualifying trust or plan.¹ The key phrase is "balance to the credit of the employee" — this is what must be paid out in full, within one tax year, to qualify.

Why periodic § 404(k) dividends don't count against that balance

Treasury Regulation § 1.404(k)-1T (a temporary regulation, last amended February 4, 1986 — so it substantially predates modern 401(k) practice, though nothing in the current Code excerpts provided contradicts its mechanics) directly addresses this exact fact pattern. It asks whether dividends paid in cash to plan participants under § 404(k) are treated as ordinary plan distributions for purposes of §§ 72, 401 and 402, and answers: generally, yes, dividends paid in cash directly to plan participants by the corporation or paid to the plan and then distributed in cash under section 404(k) are treated as distributions under the plan. However, a deductible dividend under section 404(k) is treated for purposes of section 72 as paid under a contract separate from any other contract that is part of the plan. Thus, a deductible dividend is treated as a plan distribution and as paid under a separate contract providing only for payment of deductible dividends. Therefore, a deductible dividend under section 404(k) is a taxable plan distribution even though an employee has unrecovered employee contributions or basis in the plan.²

Because the dividend is legally deemed paid under a separate contract from the rest of the participant's plan interest, it is not part of the "balance to the credit of the employee" that must be exhausted in one taxable year to satisfy the lump-sum definition. The dividend stream and the account-balance distribution are analyzed as two distinct contracts under § 72, so periodic dividend payouts do not interrupt or contaminate the single-tax-year, full-balance requirement that applies to the separate lump-sum distribution of the remaining account.

Supporting statutory signal

This reading is consistent with how Congress otherwise carved dividend distributions out of ordinary distribution restrictions elsewhere in the Code. In the 401(k) context, the regulations note that a plan does not fail to satisfy the requirements of this paragraph merely by reason of a dividend distribution described in section 404(k)(2)³ — confirming that dividend pass-throughs are treated as an exception to normal distribution-timing rules generally, reinforcing that they operate on a separate track.

Risks and limits / what to confirm

• The regulation is a temporary regulation from 1986; confirm it has not been superseded or finalized differently, and that no later Code amendment to § 404(k) or § 402(e)(4) has altered this treatment — the Code excerpts given here do not show amendment history.
• If the "periodic cash dividend" in your facts is not actually a § 404(k)(2) deductible ESOP dividend (e.g., it's just a partial in-service withdrawal mislabeled as a dividend), this separate-contract exception would not apply, and it could count against the balance-to-credit requirement.
• Confirm the separation-from-service or other qualifying event, and that the remaining balance is fully distributed within one recipient tax year, per § 402(e)(4)(D)(i).

Given the age of the regulation and the stakes of lump-sum tax treatment (10-year averaging/NUA eligibility hinges on it), this is a good fact pattern to have reviewed by a CPA or ERISA counsel with the specific plan document and distribution history in hand.
