ESOP Diversification Requirements and Tax Treatment: Rollovers and NUA

ESOP diversification requirements and tax treatment come down to two questions: when the plan has to let you move money out of employer stock, and how the IRS treats the money once it leaves. Eligibility depends on your age, years of participation, and whether the employer’s stock is publicly traded. The tax result depends almost entirely on where the money lands next—inside a qualified plan, in an IRA, or in your checking account.

Who Can Diversify and When

For most private-company ESOPs, the diversification right comes from Internal Revenue Code Section 401(a)(28)(B). You qualify once you are at least 55 years old and have completed at least 10 years of participation in the plan. Meeting both thresholds makes you a “qualified participant” and opens a six-year qualified election period. The window starts in the first plan year you satisfy both requirements, or the first plan year after December 31, 1986, whichever is later.¹ The right covers shares the plan acquired after 1986.

The Pension Protection Act of 2006 added a separate, much broader rule under Section 401(a)(35) for plans holding publicly traded employer securities.² If your ESOP holds public stock, the portion of your account funded by your own contributions or elective deferrals can be diversified at any time, with no age or service test. The portion funded by employer contributions becomes eligible after three years of service. There is no percentage cap, divestment must be offered at least quarterly, and the plan has to provide at least three diversified alternatives with meaningfully different risk and return profiles.³ A plan subject to Section 401(a)(35) also cannot satisfy the requirement by cashing you out—it has to offer in-plan alternatives.

Most private-company ESOPs fall under the older rules only. If you are unsure which set applies, the plan’s summary plan description says so.

How Much and How Often

Under the older rules, the percentages are fixed by statute. In each of the first five years of the six-year window, you can elect to diversify up to 25% of your total eligible employer stock balance. In the sixth year, the ceiling rises to 50%.¹ The percentages are cumulative, so the plan subtracts what you have already diversified when it calculates the current year’s cap.

You have to make each election within 90 days after the close of the plan year, and the plan then has 90 days after that election period ends to complete the diversification.¹ The plan administrator has to notify you of the election each year. Skip a year and you lose the ability to diversify that year’s slice; skip the whole window and the statutory right expires.

Where the Money Goes Drives the Tax Bill

An ESOP can handle a diversification election in one of two ways, and this choice is where all the tax consequences live.

The first is an in-plan transfer. The plan sells or reclassifies your employer stock and moves the proceeds into another investment option inside the ESOP itself, or into a paired 401(k) if one exists. The statute requires at least three non-employer-stock alternatives.¹ Nothing is taxable. The money keeps growing tax-deferred, and no tax event happens until you eventually take a distribution.

The second is a direct distribution. The plan liquidates the shares and pays out the cash. That forces an immediate choice: roll it into an IRA or another employer plan to preserve the tax deferral, or keep the cash and owe income tax on it in the current year. Not every ESOP offers this route, and plans under Section 401(a)(35) cannot use distributions to satisfy the diversification requirement at all.²

Direct Rollovers vs. Indirect Rollovers

If the plan sends the funds straight to an IRA or another qualified plan, no withholding is taken out and no tax is due. The check is written to the receiving custodian, not to you.

If the plan sends the cash to you personally instead, the administrator must withhold 20% for federal income tax. You cannot waive it.⁴ You then have 60 days to roll the full gross amount into an IRA or another plan to avoid tax on the distribution. The catch: you only received 80%. To complete a full rollover you have to come up with the missing 20% from other savings and deposit it along with what you got. Roll over only the 80% you received, and the withheld 20% is treated as a taxable distribution. You recover the withheld amount when you file, but only if you funded the full rollover in the meantime. Miss the 60 days and the entire amount becomes taxable.⁵

The 10% Early Distribution Penalty

Take a taxable cash distribution before age 59½ and you generally owe an additional 10% tax on top of ordinary income tax.⁶ Because many ESOP participants start diversifying at 55, the penalty is a live issue for anyone taking cash rather than rolling over or staying in the plan.

One exception matters here. If you separate from service during or after the year you turn 55, distributions from a qualified employer plan, including an ESOP, are exempt from the 10% penalty. The exception does not travel with the money. Roll it into an IRA and then withdraw before 59½, and the penalty applies. Keeping funds in the employer plan can therefore be worth more than it looks. ESOP dividend pass-throughs on allocated shares are separately exempt from the 10% penalty regardless of age.⁷

Net Unrealized Appreciation When Shares Come Out In Kind

If the ESOP distributes actual shares of employer stock rather than cash, a rule called Net Unrealized Appreciation can substantially cut your tax bill. NUA is the difference between the plan’s cost basis in the stock and its market value on the date of distribution.⁸

Ordinarily, a retirement plan distribution is taxed as ordinary income at its full value. With NUA, only the cost basis is taxed as ordinary income when the shares come out. The appreciation portion is not taxed until you sell, and when you do, it qualifies for long-term capital gains rates no matter how long you held the shares after distribution.⁹ The gap between ordinary rates and long-term capital gains rates is often 15 to 20 percentage points, so on low-basis, high-appreciation stock the savings can be significant.

To claim NUA on shares attributable to employer contributions, the distribution must qualify as a lump-sum distribution: the entire balance to your credit in the plan has to come out within a single tax year, and the distribution has to follow one of four triggering events:

Separation from service (common-law employees only, not the self-employed)
Reaching age 59½
Death
Disability (self-employed individuals only)

You do not have to take every dollar as taxable cash. You can elect NUA on the employer stock and simultaneously roll the non-stock portion of the account into an IRA. Nothing can stay behind in the plan past the end of the tax year.⁸

Gain on the shares after distribution is treated separately. Sell within a year and the post-distribution gain is short-term; hold longer than a year and it is long-term. The NUA portion itself always gets long-term treatment.

NUA is not a default choice. If the cost basis is high relative to current value, rolling into an IRA and deferring all tax may produce a better result. NUA works best when the basis is low, the appreciation is large, and you are in a bracket where capital gains rates are meaningfully lower than ordinary rates. Because the lump-sum requirement empties the plan, you cannot undo the decision once the distribution is complete. Model the numbers with a tax professional first.

Medicare Premium Surcharges on Large Distributions

If you are near Medicare age, a large taxable distribution can raise your Part B and Part D premiums two years later through the income-related surcharge. Medicare uses your modified adjusted gross income from two years prior to set the premium, so a big 2026 distribution would show up in 2028 premiums.

For 2026, the standard monthly Part B premium is $202.90. Income above $109,000 (single) or $218,000 (joint) triggers a monthly surcharge that starts at $81.20 and rises to $487.00 at the top tier ($500,000 single, $750,000 joint).¹⁰ Part D carries a separate surcharge at the same thresholds. At the top tier, a single filer could pay an additional $6,936 per year in combined surcharges. Spreading distributions across tax years, or leaning on in-plan transfers rather than cash, keeps income under the surcharge lines.

1099-R Reporting

The plan administrator files Form 1099-R with the IRS and sends you a copy for any taxable distribution and for NUA transactions.¹¹ Box 1 shows the gross distribution, Box 2a the taxable amount, and Box 6 the NUA when employer securities were distributed in kind.¹² The plan files the form; you report the income on your return using what it shows.
