An owner who sells for $20 million does not take home $20 million. Depending on entity type, deal structure, state of residence, and the planning done (or skipped) in the years before the sale, the cash that finally lands can range from just over half the headline to something much closer to it. That spread is routinely worth more than the last quarter turn of multiple everyone fought over, and unlike the multiple, much of it is controllable. This chapter is about the spread.
The organizing idea is a waterfall. Enterprise value sits at the top. Debt payoff, transaction fees, escrows and holdbacks, and taxes each take their cut on the way down, and what reaches the bottom is the only number that funds the rest of your life. Owners who think in waterfall terms make better structural decisions at every stage of a process. Owners who think in headline terms meet the waterfall at the closing table.
One necessary paragraph before the substance. This chapter is education, not advice. It describes general US federal rules as they stand in mid-2026, in simplified form; the law changes, the states differ, and your facts are your own. Nothing here accounts for your basis, your entity history, or your state. Every structure named in this chapter should be modeled by a qualified transaction tax advisor before you commit to anything, and the modeling should start long before a letter of intent exists.
Asset Sale or Stock Sale: Where the Tax Outcome Is Mostly Decided
Chapter 12 covered asset and stock (equity) structures as deal mechanics. The tax difference between them is usually the real fight.
In a stock or equity sale, the acquirer buys your shares or membership interests. You generally recognize capital gain equal to the price minus your basis: loosely, what you have invested in the stock over the years. As of 2026, the top federal long-term capital gains rate remains 20%, plus the 3.8% net investment income tax for higher earners (23.8% combined federal), and the corporate rate remains 21%; none of this was changed by the 2025 tax legislation. A founder with nominal basis who sells equity therefore pays roughly 23.8% federal on nearly the entire price, plus whatever their state takes. Single layer, capital-gain character: this is why owners’ advisors start from equity sales.
In an asset sale, your company sells its assets, and the purchase price is allocated across them in categories both sides must agree on and report consistently: the purchase price allocation. Each category has its own tax character. Inventory sold above basis produces ordinary income. Gain on equipment and vehicles is taxed as ordinary income up to the amount of depreciation you previously deducted; this is depreciation recapture, and after years of bonus depreciation many companies have fully written-off fleets and shops, so the recapture number can be large. Goodwill and going-concern value, usually the biggest allocation for a profitable services business, is capital gain. For asset-light companies the blended result often lands closer to capital-gain treatment than owners fear. For equipment-heavy companies, the ordinary-income slice deserves real modeling before pricing, not after.
The C corporation problem: one price, two taxes
For pass-through owners, asset versus stock is a question of character and degree. For a C corporation owner, it can be a question of keeping or losing an eighth of the deal.
Consider a C corporation whose assets an acquirer will buy for $10 million, with $2 million of remaining tax basis in those assets and an owner whose stock basis is nominal. The corporation recognizes $8 million of gain and pays roughly $1.7 million of federal tax at the 21% corporate rate. When the remaining $8.3 million is distributed to the owner in liquidation, the owner pays capital gains tax again: roughly $2 million more at 23.8%. Net to the owner, about $6.3 million. The same company sold as a stock sale at the same $10 million faces one layer of tax, roughly $2.4 million, and nets about $7.6 million. Same business, same headline, a $1.3 million difference, purely from structure. This is the double-tax problem, and it is why a C corporation owner should treat any asset-deal LOI as an unpriced document until a tax advisor has modeled it.
S corporations and LLCs taxed as partnerships avoid the corporate layer: gains flow through to the owners once, keeping their character (capital or ordinary) on the way. One honest caveat: an S corporation that converted from C status within the past five years can, under current rules, still face a corporate-level built-in gains tax on appreciation from its C years. If that describes you, your tax advisor needs to know before the process starts, not during it.
The step-up tug-of-war: the same dollars, claimed twice
Why do acquirers push for asset treatment at all? Basis step-up. Buy stock and the acquirer inherits the company’s old, low inside basis: no new deductions. Buy assets (or obtain asset treatment through the elections below) and the acquirer’s basis resets to the purchase price, with goodwill and most intangibles amortizable, under current federal rules, over 15 years.
The numbers are not subtle. Take a $12 million asset sale of an S corporation in which $9 million of the price is allocated to goodwill. The acquirer amortizes that goodwill at $600,000 a year for 15 years; at an illustrative 25% blended tax rate, that is roughly $150,000 a year of real cash-tax savings, more than $2 million over the amortization period and still well into seven figures on any reasonable discounted basis.
Now the owner’s side of the same deal. Suppose the allocation also puts $1.5 million on fully depreciated equipment. That $1.5 million is recapture, taxed as ordinary income; at an illustrative top ordinary federal rate in the high thirties, it costs roughly $200,000 more than the same dollars taxed at 23.8%. So asset treatment costs this owner about $200,000 and hands the acquirer a benefit worth several times that.
That gap is the tug-of-war, and it is also the resolution. The step-up is a single pool of value both sides want, and it can be shared through price. A sophisticated owner does not simply refuse asset treatment; a sophisticated owner prices it.
Illustrative example. An acquirer requests asset treatment on a $12M deal. The owner’s tax advisor models the incremental cost at roughly $200,000; the acquirer’s model values the step-up at well over $1 million. The owner agrees to asset treatment in exchange for a $400,000 price increase, a gross-up. The owner nets more than under a stock sale, the acquirer keeps most of the step-up value, and the only party unrepresented at the table is the tax code. Some version of this negotiation happens in most lower-middle-market processes.
The Named Structures, in Plain English
Two mechanisms let the parties choose their tax shape somewhat independently of the legal shape. Both appear constantly in the lower-middle market. Both are one-paragraph ideas with hundred-page execution details.
A 338(h)(10) election (and its close cousin, the 336(e) election) turns a legal stock sale into a deemed asset sale for tax purposes. The acquirer buys shares, so contracts, licenses, and the entity itself carry over, but both parties jointly elect to have the transaction taxed as if the company had sold its assets. The acquirer gets the step-up; the owner is taxed as in an asset sale, which usually costs something and is usually compensated through a gross-up in price. It is available only for certain targets, S corporations chiefly among them at this scale, and the election is all-or-nothing once made. Your tax advisor will model whether it helps you, hurts you, or should simply be priced.
The F reorganization is the lower-middle market’s workhorse for S corporation sales. In outline: before closing, the owner forms a new holding company, the existing S corporation becomes its subsidiary, and the operating company converts to a limited liability company that is disregarded for tax purposes. The acquirer then buys the LLC interests. The result is asset-sale tax treatment and a full step-up for the acquirer, with the legal continuity of an equity purchase. Unlike a 338(h)(10), the structure comfortably accommodates rollover equity, and it does not depend on the historical validity of the S election, something acquirers have learned to distrust. If you run an S corporation and expect to roll equity, expect to hear about an F reorg early. Your tax advisor will model it, and should be the one to paper it.
Key point. Engage transaction tax counsel at least 12 months before going to market. F reorganizations take time, QSBS runs on a multi-year clock, pre-sale gifting must precede the deal that fixes the value, and a C corporation’s structural problem cannot be repaired at LOI. The cheapest tax advice you will ever buy is the advice you buy early.
QSBS: Section 1202 After the 2025 Law Change
For qualified small business stock issued after July 4, 2025, the One Big Beautiful Bill Act created a tiered exclusion (50% of gain after a three-year hold, 75% after four years, 100% after five), raised the per-issuer cap to the greater of $15 million or 10x basis, and lifted the qualifying gross-asset ceiling to $75 million. Stock acquired on or before July 4, 2025 remains under the prior rules: a five-year holding period and a $10 million (or 10x basis) cap.
On paper, this is the most generous provision in the code for company owners: exclusion of gain, not deferral. The real question is who in the lower-middle market it actually helps. The answer is owners of C corporations who received their stock at original issuance and held it for years. In practice that means technology and other founders who took the C form early, often for investors, plus owners who converted well before a sale. For them, the raised ceilings matter: the $75 million gross-asset limit comfortably covers most companies at this scale when stock is issued, and a $15 million exclusion is real money.
But most lower-middle-market companies are S corporations or LLCs, and for their owners QSBS at sale time is usually a mirage. The statute requires stock issued by a C corporation, acquired at original issue, and held through the applicable period. Existing S corporation shares cannot be turned into QSBS by revoking the election, and there is no fix available at LOI. What does exist is forward planning: an LLC that incorporates starts the clock at conversion, and only appreciation after that point can qualify. If your likely exit is four or more years away, your company fits the asset limits, and you can live with C corporation status in the meantime (a real cost with real tradeoffs), the question is worth asking now rather than never. Know also that some states do not follow the federal exclusion. This is a years-ahead decision with a heavy modeling burden: your tax advisor will model it against the pass-through status quo before you change anything.
Getting Paid Over Time: Installment Sales and Earnouts
Seller notes and other deferred payments generally qualify for installment treatment: you recognize gain as payments arrive rather than all at close, spreading the tax across the life of the note. Three practical wrinkles. Depreciation recapture does not wait; it is generally taxed in the year of sale even if the cash comes later. Interest on the note is ordinary income as received. And deferral is not automatically desirable: an owner can elect out of installment treatment and pay tax up front, which occasionally makes sense when rates are expected to rise or offsetting losses are available. Remember the risk stacking, too: a deferred dollar is both a credit exposure to the acquirer and a tax obligation whose neat schedule assumes you actually collect. Have the note modeled against cash at close on an after-tax, risk-adjusted basis.
Earnout taxation is its own thicket and depends on structure. Contingent payments can be taxed under installment-sale principles with imputed interest carved out of each payment, and payments tied to the owner’s continued employment risk being recharacterized as compensation, taxed at ordinary rates plus payroll taxes instead of as capital gain. The drafting decides, not the intent. If an earnout is a meaningful slice of your consideration, the tax model belongs inside the LOI negotiation, not after it.
Common pitfall. The LOI signed before the tax model. An owner agrees to price, an asset structure, a seller note, and an employment-linked earnout in a three-page LOI, then brings it to a tax advisor, who calculates that the agreed structure costs several hundred thousand dollars more than an alternative the acquirer would readily have accepted. Renegotiating structure inside exclusivity means asking for concessions with no competitive pressure left. The model costs a few thousand dollars. Run it first.
Rollover Equity and the Deferred Second Bite
Rollover equity, keeping a stake in the recapitalized company (Chapter 12 covers the economics), can usually be structured so the rolled portion is not taxed at close. Where the acquirer’s vehicle is a partnership for tax purposes, contributing equity in exchange for partnership interests can qualify for nonrecognition under the partnership rules. Where it is a corporation, an exchange into acquirer stock can qualify under the corporate nonrecognition rules. The word doing all the work is “structured”: handled casually, a rollover is just a taxable sale followed by a stock purchase; handled properly, often via the F reorganization above, you pay tax only on the cash portion and defer the rest until the second bite. Deferred, not forgiven: the rolled equity carries your old basis forward, and the tax comes due when the platform sells. The rollover’s tax treatment and its investment merits are separate questions; have both modeled.
State Taxes, Residency, and the Florida Question
Federal tax is half the story. State tax on a large gain can run to seven figures, and this is where the folklore lives. Yes, owners really do move from high-tax states to Florida or Texas before a sale, and yes, it can work. It works when the move is real, established well before the gain, and survivable under a residency audit, which high-tax states pursue aggressively around large transactions; domicile is a facts-and-circumstances question about where your life actually is, not where your mail goes. It fails when the move is a lease signed the quarter before closing. And it does not always matter even when done well: several states tax nonresidents on gain sourced to businesses operating there, particularly in asset sales and deemed asset sales, so the company’s footprint can keep a state’s hand in the deal after yours has left. Residency planning is legitimate, slow, and intensely personal. Your tax advisor, ideally one fluent in your departure state’s audit practice, will model it.
A Note on Estate Planning
One flag, planted early because the opportunity expires early. The most powerful estate planning around a sale happens before the deal prices the company. Gifting or selling stock to trusts for your family while the company’s value rests on an appraisal, rather than a signed purchase agreement, can move future appreciation out of your estate on far better terms than anything available after LOI. This is specialist territory with its own multi-year rhythms. If your net worth is concentrated in the business and a sale is plausible within five years, talk to estate counsel now; the option quietly disappears the day a deal fixes your number.
The Waterfall: A Worked Example
Time to put the whole chapter into one column of numbers. Consider a $20 million enterprise value equity sale of an S corporation on cash-free, debt-free terms. The company carries $3.0 million of debt, paid off at close. Transaction fees, covering advisory, legal, and accounting, total $0.9 million. The purchase agreement holds back $1.6 million in escrow for 18 months against indemnity claims. Taxes at illustrative blended rates come to $3.2 million: here, roughly the 23.8% combined federal rate applied to the owner’s gain after basis and selling costs, assuming a no-income-tax state. A resident of a high-tax state would owe meaningfully more, and your own blended rate depends on basis, allocation, and structure.
The same walk in table form (all figures illustrative):
| Step | Amount | Running total |
|---|---|---|
| Enterprise value (equity sale) | $20.0M | $20.0M |
| Debt payoff | ($3.0M) | $17.0M |
| Transaction fees | ($0.9M) | $16.1M |
| Escrow (held back 18 months) | ($1.6M) | $14.5M |
| Taxes (illustrative blended rates) | ($3.2M) | $11.3M net cash at close |
Net cash at close: $11.3 million on a $20 million headline, about 56 cents on the dollar the day the wire hits. If the escrow comes home intact at month 18, as it commonly does when disclosure and diligence were done well, the total rises to $12.9 million.
Two simplifications keep this walk honest. First, the example taxes the full gain at close; whether escrowed dollars are taxed at close or on release depends on how the agreement is drafted, one more line for the tax model. Second, it ignores the working capital true-up, which can move the number in either direction (Chapter 12). The lesson is not the specific figures, which are illustrative from top to bottom. The lesson is that every line except the first is negotiable, plannable, or both, and that owners who see the waterfall a year early keep more of the top line than owners who first see it at close.
The Bottom Line
- The only number that matters is after-debt, after-fee, after-tax proceeds; manage the waterfall, not the headline.
- Asset versus stock treatment, and the elections that bridge them, decide most of the tax outcome, and the acquirer’s step-up is value to be priced, not conceded.
- C corporation owners face a double-tax problem that no LOI-stage cleverness can fully fix; know your structural shape years before you sell.
- QSBS is a genuine prize for qualifying C corporation founders and, without multi-year planning, out of reach for the S corporation and LLC owners who make up most of this market.
- Deferral tools such as installment notes and rollover equity spread tax rather than erase it, and every deferred dollar carries counterparty risk alongside its tax profile.
- Engage a transaction tax advisor at least 12 months before going to market, and never sign a letter of intent before the tax model is built.
