Distributions in Excess of AAA: AEP Ordering, Basis, and Elections

When an S corporation distribution exceeds the Accumulated Adjustments Account, the excess is not automatically tax-free. Its treatment depends on whether the corporation carries accumulated earnings and profits (AEP) from a prior C corporation period and how much stock basis the shareholder still has. Depending on those two facts, the excess can be a qualified dividend, a tax-free return of capital, a capital gain, or some combination running through all three.

Two Different Paths Depending on AEP

The single fact that controls the outcome is whether the S corporation has any accumulated earnings and profits left over from a C corporation past. Corporations that have always been S corporations have no AEP, and the analysis is short. Corporations that converted from C status often do, and the analysis becomes a multi-tier waterfall.

If the corporation has no AEP, a distribution in excess of the AAA is a tax-free return of capital to the extent of the shareholder’s remaining stock basis. Anything beyond basis is treated as gain from the sale of the stock — capital gain, long-term if the stock has been held more than a year.

If the corporation does carry AEP, the excess runs through a mandatory ordering under IRC Section 1368(c) before any of it reaches stock basis. That’s where dividend treatment enters the picture, and where an unexpected tax bill usually shows up.

The Ordering When AEP Is Present

Once a distribution passes the AAA and the corporation has AEP, the remaining amount is sourced in this fixed order:

Accumulated earnings and profits, taxed to the shareholder as a dividend.
The Other Adjustments Account (OAA), which holds tax-exempt income earned during S years — distributed tax-free.
The shareholder’s remaining stock basis, reducing basis dollar-for-dollar as a tax-free return of capital.
Any amount left over, taxed as gain from the sale or exchange of the stock.

A small subset of corporations that elected S status before the Subchapter S Revision Act of 1982 also carry a Previously Taxed Income account under IRC Section 1379(c), which slots in between AAA and AEP. This is rare.

The shareholder and the corporation cannot pick a different order. The ordering is set by statute, and each tier must be fully consumed before the next tier is reached.

Dividend Treatment When the Excess Hits AEP

The portion of a distribution sourced from AEP is the only situation in which an S corporation distribution produces dividend income. The AEP pool represents profits the company earned and paid corporate-level tax on during its C years but never distributed. When those earnings finally leave the company under S status, they carry their old dividend character because shareholders never included them in pass-through income.

Two features of the AEP tier catch shareholders off guard. First, an AEP distribution does not reduce stock basis. The money comes from a corporate-level pool independent of any shareholder’s investment. Second, the corporation reports the amount on Form 1099-DIV, and the shareholder picks it up as dividend income on Form 1040.

Qualified Dividend Rates

AEP distributions generally qualify for the preferential rates that apply to qualified dividends rather than ordinary income rates. The shareholder must have held the stock for more than 60 days during the 121-day period beginning 60 days before the ex-dividend date, a requirement most long-time S corporation owners meet easily.¹

For 2026, qualified dividend rates track the long-term capital gains brackets:

0% on taxable income up to $49,450 (single), $98,900 (married filing jointly), or $66,200 (head of household).
15% on taxable income above the 0% threshold up to $545,500 (single), $613,700 (married filing jointly), or $579,600 (head of household).
20% on taxable income above those levels.¹

Most shareholders receiving AEP distributions land in the 15% bracket. That’s a real tax cost compared to zero tax on the AAA portion, but well below ordinary rates.

The Net Investment Income Tax

Shareholders above certain income thresholds face an additional 3.8% Net Investment Income Tax on AEP distributions. The NIIT applies to the lesser of net investment income or the amount by which modified adjusted gross income exceeds $250,000 (married filing jointly), $200,000 (single or head of household), or $125,000 (married filing separately).² Those thresholds do not adjust for inflation.

Dividend income from AEP counts as investment income for NIIT purposes even if the shareholder materially participates in the S corporation’s business. Material participation shields pass-through operating income from the NIIT; it does not shield AEP dividends. A shareholder in the 15% qualified dividend bracket who also owes NIIT faces an effective 18.8% on the AEP portion.

When the Excess Reaches Basis and Then Capital Gain

After AEP is fully distributed (and OAA, if any), the next dollars come out of the shareholder’s remaining stock basis. This is a tax-free return of capital, and basis drops dollar-for-dollar.³

If the distribution is large enough to push basis to zero with money still to go, the excess is treated as gain from the sale or exchange of the stock. For shareholders who have held their stock more than a year, that gain is long-term capital gain, taxed at the same 0%, 15%, or 20% brackets that govern qualified dividends.⁴¹ Short-term gains face ordinary rates. The NIIT can apply here too, pushing the effective rate to 18.8% or 23.8% on the final tier.

By the time a distribution has run this far, every pool has been consumed: previously taxed S corporation income (AAA), old C corporation earnings (AEP), tax-exempt income (OAA), and the shareholder’s invested capital (basis). What comes next is pure economic profit.

Tracing a Distribution Through the Tiers

Say an S corporation with a C corporation history distributes $100,000 to a shareholder. The AAA is $60,000, AEP is $20,000, and the shareholder’s stock basis before the distribution is $75,000.

The first $60,000 comes from the AAA, tax-free, and drops the shareholder’s stock basis from $75,000 to $15,000. The next $20,000 comes from AEP and is taxed as a qualified dividend, without touching stock basis. The next $15,000 is a tax-free return of the shareholder’s remaining stock basis, bringing basis to zero. The final $5,000 is capital gain.

The shareholder walks away with $75,000 of tax-free cash, a $20,000 qualified dividend, and a $5,000 capital gain — from a single $100,000 check.

When Multiple Distributions Share One AAA

If the corporation makes more than one distribution during a year and total distributions exceed the AAA balance, the AAA is allocated proportionally across all distributions for the year. Two equal distributions with an AAA that covers only half the combined total each get half sourced from AAA and half from the next tier. The corporation cannot assign all of the AAA to one distribution and none to another.

This matters for planning. Shareholders sometimes assume the first distribution of the year clears the AAA first and later distributions absorb the AEP hit. That is not how the allocation works.

Property Distributions Change the Math

When the distribution is property rather than cash and its fair market value exceeds the corporation’s adjusted tax basis in it, the corporation recognizes gain as if it had sold the property to the shareholder at fair market value.⁵ That gain passes through to shareholders on their K-1s and increases their stock basis. Only then is the distribution itself measured, at fair market value, and run through the same ordering tiers.

The gain recognition can create room in the AAA and in stock basis that wasn’t there before the distribution. It also creates immediate pass-through income the shareholders owe tax on, even in cases where the property distribution itself would fall entirely within the AAA. Running the math before the distribution is the only way to see the actual result.

Elections to Eliminate the AEP Problem

Because AEP is what triggers dividend treatment on distributions past the AAA, corporations that want to end this problem can use one of two elections to clear it out.

Distribute AEP First

Under IRC Section 1368(e)(3), an S corporation can elect to reverse the normal ordering and distribute AEP before the AAA. Shareholders accept dividend treatment on the distribution in exchange for permanently reducing or eliminating the AEP balance. This is most useful in a year when shareholders sit in low brackets or when the corporation is close to the excess passive investment income tax trigger under IRC Section 1375. The election is made by attaching a statement to a timely filed Form 1120-S (with extensions) identifying the election and stating that each affected shareholder consents.⁶ It applies for that tax year only.

The Deemed Dividend Election

Treasury Regulation Section 1.1368-1(f)(3) allows the corporation to eliminate some or all of its AEP without moving any cash or property. The corporation is treated as distributing the elected amount to shareholders in proportion to their ownership, and the shareholders are treated as contributing it back to the corporation, all on the last day of the tax year.⁶

The deemed dividend cannot exceed AEP remaining on the last day of the tax year, reduced by any actual AEP distributions made during the year. It automatically carries the AEP-first election with it. Every affected shareholder must consent, and the corporation attaches a statement to its timely filed return specifying each shareholder’s share.⁶

The shareholders still owe tax on dividend income they never received in cash. But once the election is made, the AEP is gone, and future distributions run under the simpler rules that apply to corporations without AEP.

How the Excess Gets Reported

The corporation communicates each tier of the distribution to shareholders on Schedule K-1 (Form 1120-S), separately identifying amounts sourced from AAA, AEP, and OAA. Any AEP portion also lands on Form 1099-DIV as dividend income.⁷

The AAA, AEP, and OAA balances themselves live on Schedule M-2 of Form 1120-S.⁸ Errors at the corporate level flow directly into every shareholder’s return.

Shareholders track their own stock basis and file Form 7203 whenever they receive a non-dividend distribution, claim a share of loss, dispose of stock, or receive a loan repayment.⁹ The form is what proves how much of a distribution in excess of AAA was tax-free basis recovery and where capital gain began.

Penalties for Getting the Characterization Wrong

Treating an AEP dividend as a tax-free AAA distribution, or missing a capital gain when basis has hit zero, produces an underpayment. The IRS imposes a 20% accuracy-related penalty on the portion of any underpayment attributable to negligence or a substantial understatement. For individuals, a substantial understatement means the understated amount exceeds the greater of 10% of the tax that should have been reported or $5,000.¹⁰

A shareholder who treats a $50,000 AEP distribution as tax-free and later gets audited owes tax on the dividend income plus 20% of that underpayment, plus interest from the original due date. Estimated tax penalties may add to that if quarterly payments weren’t adjusted. Accurate AAA and AEP tracking at the corporate level, together with honest basis calculations at the shareholder level, is what keeps a distribution in excess of AAA from becoming an audit event years later.
