IRC Section 356: Boot, Gain Recognition, and Basis Rules

Under IRC Section 356, when you receive cash or other non-stock property (boot) along with qualifying stock in a corporate reorganization, you recognize gain equal to the lesser of your realized gain on the exchange or the value of the boot. The rest of your gain stays deferred inside the basis of the new stock. Whether the recognized gain is taxed as capital gain or as a dividend depends on how the exchange looks when you test it under the stock redemption rules.

That is the whole mechanic. The details below tell you what counts as boot, how to run the math, how the character of the gain is decided, and where the rules shift against you.

What Counts as Boot

Boot is anything you receive in a reorganization exchange that is not stock of the acquiring or distributing corporation. Cash is the obvious case. Short-term notes and tangible property also count. Two less obvious categories catch people off guard.

Securities above the principal you surrendered. Securities are not automatically tax-free. Under Section 356(d), the term “other property” generally includes securities, and they escape boot treatment only to the extent Sections 354 or 355 would permit.¹ In practice, two situations create boot: if the principal amount of securities you receive exceeds the principal amount you surrendered, the excess is boot;² and if you receive securities but surrendered none, the entire principal amount is boot.

Nonqualified preferred stock. Section 356(e) treats nonqualified preferred stock as boot even though it is technically equity.³ Preferred stock is “nonqualified” when it has features that make it look more like debt: the holder can force the issuer to buy it back, the issuer is required to redeem it, the issuer has a right to redeem and is more likely than not to exercise it, or the dividend rate floats with interest rates or similar benchmarks.⁴ The first three triggers apply only if the right or obligation can be exercised within 20 years of issue.

One point worth being clear about: receiving boot does not blow up the reorganization. If the transaction otherwise qualifies under Section 368, shareholders who receive only stock still pay no tax. Section 356 only governs the shareholders who received something extra.

How Much Gain You Recognize

The calculation runs in two steps.

Step one: realized gain. Add the fair market value of the stock you received to the fair market value of the boot. Subtract your adjusted basis in the stock you surrendered. That number is your realized gain, which is the full economic profit on the exchange.

Step two: apply the cap. You recognize gain equal to the lesser of your realized gain or the value of the boot.¹ The cap keeps the boot from pulling more gain into current tax than you actually made.

Say you surrender stock with a $100,000 basis and receive new stock worth $150,000 plus $20,000 in cash. Realized gain is $70,000. Recognized gain is the lesser of $70,000 or $20,000, so you report $20,000. The remaining $50,000 of gain rides inside the basis of your new stock.

Now flip the facts. Same transaction, but your basis in the old stock was $160,000. Realized gain is only $10,000 ($170,000 received minus $160,000 basis). Even though you got $20,000 in cash, recognized gain is capped at $10,000, because realized gain is the lower number.

Losses Stay Deferred

Section 356 never lets you recognize a loss. If your basis in the old stock is higher than everything you received, the loss is deferred.¹ Boot does not unlock it. The loss gets built into the basis of your new stock and comes out only when you sell.

Capital Gain or Dividend

Knowing the amount of recognized gain is only half the answer. The character of the gain decides the rate. Section 356(a)(2) says that if the exchange “has the effect of the distribution of a dividend,” the recognized gain is dividend income to the extent of your share of the corporation’s accumulated earnings and profits. Anything above that is capital gain.¹

The earnings-and-profits ceiling is a hard limit. If the corporation has only $5,000 of accumulated E&P and you recognize $20,000 of gain, at most $5,000 is taxed as a dividend. The other $15,000 is capital gain, period.

The Clark Hypothetical Redemption Test

The Supreme Court set the dividend-equivalence test in Commissioner v. Clark. You imagine the exchange in two steps: first, you receive only stock of the acquiring corporation; second, the acquirer immediately redeems enough of that stock to match the boot you actually got.⁵ You then test that hypothetical redemption under Section 302 to see if it qualifies for exchange treatment or looks like a dividend.

In Clark, the taxpayer’s interest in the acquiring corporation dropped from 1.3% to 0.9% after accounting for the boot. The roughly 29% reduction easily cleared the “substantially disproportionate” safe harbor under Section 302(b)(2), which requires the shareholder to give up more than 20% of voting control and hold less than 50% afterward.⁵

Section 302(b) gives four paths to exchange (capital-gain) treatment for the hypothetical redemption:

Substantially disproportionate under 302(b)(2): voting percentage drops more than 20% and you hold less than 50% afterward.⁶
Complete termination under 302(b)(3): your entire interest is eliminated.
Not essentially equivalent to a dividend under 302(b)(1): a “meaningful” reduction in interest even if the numerical tests are missed.⁷
Partial liquidation under 302(b)(4): the distribution reflects a genuine contraction of the business.

Clear any one test and the boot is capital gain. Fail all four and the boot is a dividend up to your ratable share of earnings and profits.

Why Most Shareholders Get Capital Gain

The Clark test measures your interest in the acquiring corporation after the deal. Because the acquirer is usually much larger than the target, a target shareholder’s percentage in the combined entity is small. A 10% owner of a small target may end up with less than 1% of the acquirer. That kind of dilution clears Section 302 easily. The math only tightens for controlling shareholders of the acquiring corporation, where the boot may not shift the ownership percentage enough.

Why Corporate Shareholders May Prefer Dividend Treatment

Individual shareholders pay the same preferential rate on qualified dividends and long-term capital gains, so the character distinction often doesn’t change the bill. Corporate shareholders are different. A corporation receiving boot characterized as a dividend can claim the dividends received deduction, which excludes 50% of most dividends from tax, 65% if the corporate shareholder owns at least 20% of the payer, or 100% for members of the same affiliated group.⁸ Capital gain is fully taxable at the corporate rate. Dividend treatment can be the better outcome for a corporate holder.

Spin-Offs Are Treated Harsher Than Split-Offs

Section 356 treats boot differently depending on whether you actually gave up any stock. The split matters most in corporate separations under Section 355.

In a split-off, you surrender parent stock in exchange for subsidiary stock, and boot may come along. Because stock is actually exchanged, Section 356(a) governs: the lesser-of rule caps your gain, and the Clark test decides character.¹

In a spin-off, the parent distributes subsidiary stock pro rata and nobody surrenders anything. When boot shows up here, Section 356(b) applies, and the result is harsher: the entire value of the boot is treated as a property distribution under Section 301.¹ Section 301 taxes the boot first as a dividend up to the corporation’s earnings and profits, then as a tax-free return of capital against stock basis, then as capital gain once basis hits zero.⁹ There is no cap at realized gain here. A shareholder with little or no economic gain can still face full dividend treatment on the whole boot amount if the corporation has sufficient E&P.

Basis and Holding Period After the Exchange

Once the dust settles, you need to get the basis and holding period of the new stock right. If you don’t, the deferred gain gets taxed twice when you eventually sell.

Basis of the New Stock

Start with the adjusted basis of the old stock. Subtract the fair market value of any boot (cash included). Add back the gain you recognized on the exchange.¹⁰ The formula keeps the deferred gain inside the new stock and lets it come out on a future sale.

Walking the first example through: $100,000 old basis, minus $20,000 cash boot, plus $20,000 recognized gain, equals $100,000 basis in the new stock. The $50,000 of deferred gain is still there, embedded in shares you now hold at a $100,000 basis against $150,000 of value.

Basis of Boot Property

If the boot is property rather than cash, its basis is its fair market value on the exchange date.¹⁰ You already paid tax on gain attributable to that property, so a fair-market-value basis stops the same gain from being taxed again.

Holding Period

Your holding period in the new stock includes the time you held the old stock, as long as the old stock was a capital asset and the new stock takes a substituted basis. This “tacking” rule under Section 1223 means you can qualify for long-term capital gain rates on an immediate sale of the new stock if you held the old shares for more than a year.¹¹ Boot property does not get a tacked holding period. Because it takes a fair-market-value basis instead of a substituted basis, its holding period starts fresh on the exchange date.

Reporting

Shareholders over certain ownership thresholds have to file a statement with their return for the year of the reorganization. For acquisitive reorganizations under Section 354, a “significant holder” is someone who owned at least 1% of the corporation’s stock by vote or value immediately before the exchange (5% if the stock was publicly traded), or who held securities with a basis of $1 million or more. These holders report the names and EINs of the parties, the date of the transaction, the fair market value of all stock or securities transferred, and the basis in the surrendered shares. Similar rules apply to “significant distributees” in Section 355 separations.

Everyone else just reports the recognized gain on their individual return: capital gain on Schedule D, dividend income on the dividend lines. In a public-company deal, the acquiring or distributing corporation typically sends a statement or Form 1099 that spells out the allocation of what you received, which makes the filing straightforward.
