S-Corp Distributions Over Basis: The 23.8% Surprise

#What the distribution trap actually is

Every S-corp owner has two numbers that matter at tax time. One is the income or loss on the K-1. The other is the adjusted basis of their stock. Most owners know the K-1 number. Most do not know their basis.

That gap has a cost.

When your S-corp sends you a distribution, the IRS runs a simple test under IRC §1368. Does the distribution go above your adjusted stock basis? If not, the cash is a tax-free return of capital. You already paid tax on that money when it flowed through as income. Now you are just pulling it back out. If the distribution does go above your basis, the IRS treats the extra as gain from the sale of stock.

That extra is a capital gain. It is usually long-term. You have almost certainly held your S-corp stock for more than one year. It is taxed at 0%, 15%, or 20%, depending on your income. Add 3.8% Net Investment Income Tax (NIIT) on top if your modified adjusted gross income (MAGI) tops $200,000 single or $250,000 MFJ.

In 2026, the top combined rate on that gain is 23.8% for owners above the NIIT threshold. On a $100,000 excess distribution, that is $23,800 of tax. And it falls on cash you thought you had already paid for.

Two different rules can apply, depending on your S-corp’s history:

• §1368(b), no accumulated earnings and profits (E&P): This is the case for most pure S-corps set up directly as an S-corp. Distributions reduce your basis dollar for dollar. Anything over basis becomes capital gain.
• §1368(c), with accumulated E&P: This applies when an S-corp was previously a C-corp. Here, distributions come out in order. First from the Accumulated Adjustments Account (AAA). Then from accumulated E&P, taxed as dividends at qualified dividend rates. Then as return of basis. Then as capital gain for anything left over. If your S-corp was ever a C-corp, this matters a lot. Your tax advisor needs to track AAA and accumulated E&P as two separate accounts.

For most founders who set up directly as an S-corp, §1368(b) is your rule.

#How your S-corp stock basis is built and adjusted

IRC §1367 governs your basis in S-corp stock. It starts with what you paid for the stock, or what you contributed to the corporation. Then it changes every year based on the corporation’s activity.

Basis increases under §1367(a)(1) for:

• Your pro-rata share of ordinary business income (Schedule K-1, Box 1)
• Your pro-rata share of separately stated income items (capital gains, Section 1231 gains, royalties, interest)
• Tax-exempt income that flows through to you
• The excess of depletion deductions over the basis of the depleted property (a niche item for oil and gas owners)

Basis decreases under §1367(a)(2) for:

• Distributions not included in your gross income (the return-of-capital distributions we are discussing)
• Your share of separately stated losses and deductions (capital losses, Section 1231 losses)
• Your share of non-separately stated loss (ordinary business loss, Schedule K-1, Box 1 when negative)
• Nondeductible, non-capital expenses (the 50% disallowed portion of meals, certain fines, penalties)
• The depletion deduction for oil and gas to the extent it exceeds the property’s basis

Here is the critical rule: your stock basis cannot go below zero. If losses would push it below zero, those losses are suspended instead. They carry forward to a future year. There, they wait for basis to come back, through income or a fresh capital contribution. This sounds like a relief. But it hides a danger. We cover that danger in the ordering rules below.

For the full walk-through of the annual calculation, see our guide on S-corp shareholder basis tracking. It also covers the schedule your CPA should hand you every year alongside your K-1.

#The ordering rules that determine your safety margin

This is the part most owners skip. It is the exact source of the tax surprise.

Your basis adjustments are not applied at random. Treasury Regulation §1.1367-1(f) sets a specific four-step order for each tax year. That order decides whether your distributions clear the basis floor or trigger a gain.

The four-step ordering:

1. First, increase basis for items of income (ordinary income, separately stated income items, tax-exempt income flowing through for the year)
2. Second, decrease basis for distributions that are not taxable under §1368 (the return-of-capital check)
3. Third, decrease basis for nondeductible, non-capital expenses and oil/gas depletion
4. Fourth, decrease basis for items of loss and deduction (ordinary losses, capital losses, separately stated deductions)

Read that order carefully. Income goes in first. A strong profit year lifts your basis before distributions chip away at it. Losses hit last, after distributions have already reduced your basis.

This order is why so many owners get surprised. In a loss year, taking a large distribution is extra dangerous. Your basis gets no lift from income, because there was none. The distribution reduces it directly. Then the loss cannot deduct, because there is no basis left. You end up with a capital gain from the distribution, plus suspended losses you cannot use yet.

Our S-corp loss limitation guide covers one key difference in depth. Losses that exceed your basis are suspended. They wait for future basis. A distribution that exceeds your basis works differently. It does not suspend. It triggers a gain right away. There is no carryforward and no deferral. The tax is due.

#The capital-gain cost: what you actually owe when you exceed basis

When a distribution goes above your stock basis under §1368(b)(2), you recognize long-term capital gain on the extra. This assumes you have held the stock more than one year, which is almost always true for operating S-corps. Here is what that costs in 2026:

• 0% rate: taxable income up to $49,450 (single) or $98,900 (married filing jointly)
• 15% rate: above those amounts up to $545,500 (single) or $613,700 (MFJ)
• 20% rate: above those amounts
• NIIT (3.8%): on net investment income for MAGI above $200,000 (single) / $250,000 (MFJ) under IRC §1411

The sting is real, but often misunderstood. An S-corp owner in the 15% capital gains bracket pays less tax on an excess distribution than they would on ordinary income. But they expected to pay nothing on distributions. That gap causes real cash-flow problems, especially when the owner already spent the money.

Here is one more thing to know. Once you recognize capital gain under §1368(b)(2), your stock basis hits zero. You have spent your basis. Every future distribution now triggers more capital gain right away, until fresh income lifts your basis again. This is why letting your basis erode to zero is not a one-time event. It compounds.

#Two worked examples: the trap and the plan

#Example 1: Sarah walks into a $65,000 capital gain

Sarah owns 100% of her S-corp. At the start of the year, her stock basis is $15,000. The corporation has a rough year. A net ordinary loss of $20,000 flows through to her K-1. During the year, Sarah takes $80,000 in distributions to cover personal expenses. She does not realize her basis is thin.

Here is the §1.1367-1(f) order applied at year-end:

Sarah owes capital gains tax on $65,000. At the 15% federal rate, that is $9,750 of federal tax on money she pulled from her own business. Add her state’s capital gains rate and the bill grows more. She also carries a $20,000 suspended loss forward to a future year, waiting for basis to come back. Her tax preparer files the return showing a Schedule D gain. Sarah is shocked. She assumed distributions were always tax-free.

#Example 2: Marcus plans ahead and lands with $50,000 of remaining basis

Marcus also owns 100% of his S-corp. At the start of the year, his stock basis is $10,000. The business has a strong year. $120,000 of net ordinary income flows through on his K-1. Marcus takes $80,000 in distributions, after checking with his CPA that the year’s income will be enough.

Here is the §1.1367-1(f) order applied at year-end:

Marcus owes zero capital gains tax on his distributions. The $80,000 is a tax-free return of capital, fully covered by his basis. He ends the year with $50,000 of remaining basis, ready to absorb future distributions or losses.

The only difference between Sarah and Marcus is this: Marcus tracked his basis before wiring himself money. He knew the year’s income would lift his basis to $130,000 before distributions reduced it. Sarah did not know her basis, and she did not run the numbers.

#Distribution planning: four moves to stay above the line

Planning around IRC §1368 is not complicated. You just need to know your number before you act on it.

#Know your basis before you wire

Before taking any big distribution, pull your current basis schedule. Your CPA should produce this every year as its own document, separate from the K-1. If your accountant hands you only the S-corp return and a K-1, ask them directly for your shareholder basis schedule. If they say they do not track it, fix that before your next distribution.

Our S-corp basis tracking guide covers how the annual schedule is built, and what it should show you each year.

#Time large distributions to income years

The §1367 order can work for you when you use it on purpose. Income raises your basis before distributions reduce it. A strong profit year lifts your basis first. Then distributions taken after that land on a cushioned floor.

Here is the practical rule. Before wiring yourself any distribution above $20,000, estimate your year-end K-1 income. If current-year income plus your opening basis will not cover the distribution with a modest buffer left over, scale back. A delayed distribution costs you nothing. A capital gain triggered by bad timing costs real money.

#Spread large distributions across tax years

If you have co-owners, pay every owner the same amount per share. Uneven or off-timed payouts can put your S election at risk, so fix that fast. Say you need a lot of cash and your basis is thin. Consider a smaller distribution this year, then a larger one next year. Wait until the business earns fresh income. Spreading the cash over two years gives income more time to build basis. A single large lump sum can punch straight through a low basis floor.

This helps most right after a loss year. Taking distributions right after a loss year means you start with basis already squeezed by the loss, since losses hit last at year-end. Waiting for the recovery year lets income restore basis first, before you pull cash.

#Make additional capital contributions to restore basis

Say you already took distributions above your basis. Or you expect to need distributions from a low-basis spot. An extra capital contribution to the S-corp raises your stock basis dollar for dollar. The trade-off is that cash goes in before it comes back out. For owners with other liquid assets, that trade is often worth it to avoid a capital gain.

One thing to know: this must be a real contribution. Money actually wired into the corporate bank account, and recorded as paid-in capital on the books, raises your basis as of that date. Contributing before the distribution is clean. Trying to claim a basis credit after the fact, without an actual contribution, is not.

#Common questions

Does the capital gain apply to all S-corp distributions, or only part of them? Only the part that goes above your adjusted stock basis is capital gain under §1368(b)(2). Distributions within your basis are tax-free returns of capital. Only the excess over zero triggers the tax. If your basis is $80,000 and you take a $90,000 distribution, only $10,000 is taxable as capital gain.

If my S-corp was previously a C-corp and has accumulated E&P, does that change the analysis? Yes, a lot. Under §1368(c), distributions from an S-corp with accumulated E&P come out in a different order. First the Accumulated Adjustments Account (AAA). Then accumulated E&P, taxed as a dividend at qualified dividend rates, not as capital gain. Then return of basis. Then capital gain for anything left over. If your S-corp converted from a C-corp, your advisor needs to track both the AAA and accumulated E&P on their own. The §1368(b) rule covered in this article applies to pure S-corps with no accumulated E&P.

Can I take distributions equal to my entire stock basis each year? Yes. Distributions up to your basis are fully tax-free. The rule is that the excess over basis triggers gain. Staying at or below your basis means zero capital gain. Many owners plan their distributions to land exactly at the basis limit. They leave anything above that in the corporation for next year, after income rebuilds the floor.

How does this work if I own less than 100% of the S-corp? Basis adjustments apply pro-rata to your ownership share. Say you own 40% of the S-corp and the corporation earns $200,000 in net income. Your basis grows by $80,000. If the corporation makes $300,000 of total distributions and your share is $120,000, your basis drops by $120,000. The excess-over-basis test looks only at your allocable share, not the corporation’s total distributions.

What happens to suspended losses if I trigger a capital gain from an excess distribution? Suspended losses do not offset a capital gain from an excess distribution. Say your basis was zero going into the year, because prior losses already ate it. A loss suspended last year still sits in your carryforward. That suspended loss does not reduce this year’s gain. Both the gain and the suspended loss exist at the same time. The suspended loss becomes deductible in a future year, once basis comes back through income or a new contribution.

Is the capital gain from an excess distribution subject to self-employment tax? No. Gain under §1368(b)(2) is capital gain, not self-employment income. It does not owe SE tax or FICA. The 3.8% Net Investment Income Tax can still apply if your income is over $200,000 (single) or $250,000 (joint). If you work in the business, part or all of the gain may sit outside this tax. Ask your tax pro to run the numbers. The NIIT is separate from self-employment tax, and it applies to net investment income, which includes capital gains.

Does the AAA account track the same thing as my stock basis? No. The Accumulated Adjustments Account and your personal stock basis are entirely separate numbers. The AAA is a corporate-level account that tracks undistributed S-corp income since the S election. Your stock basis is a shareholder-level number. It includes what you paid for the stock, your later contributions, and income less distributions and losses. Loans you make to the company create a separate debt basis. Debt basis does not protect a distribution from gain. If the company has no accumulated E&P, the AAA does not decide how your distribution is taxed. Your stock basis does. The AAA matters only when the company has accumulated E&P from C-corp years.

My S-corp had a profitable year but I still got a capital gain notice. How? The most common reason: prior-year losses or distributions had already pushed your basis down to near zero before this year started. Even a profitable year may not fully replace what was lost in earlier years. So current-year income lifts basis some, but not enough to cover the full distribution. The second most common reason is a timing mismatch mid-year. The owner wired themselves a large distribution before year-end income was fully estimated, and actual income came in lower than projected. The ordering rules apply at year-end, so the math still works out on paper. But if income came in below expectations, your basis protection is smaller than you thought.

#Ready to track your basis before it surprises you?

Look, the distribution trap is entirely avoidable. You need one thing: your basis number, updated every year, before you take cash out of the business. Most owners find out their basis is low after the tax return is filed, when the damage is already done.

We track shareholder basis as standard practice for every S-corp client on our tax planning and advisory service. We run the basis schedule and flag your distribution limit before you hit it. We coordinate timing with your year-end income, so a distribution never turns into a surprise capital gain.
