Chapter 4 of 6Deal Structure and Transaction Tax
How the Deal Is Structured, and What You Keep
Two identical headline prices can produce very different amounts of money in your account. This is the chapter where that difference gets decided.

The short versionIf you read nothing else on this page, read these three.
- 1Buyer and seller want opposite structures for structural reasons, not adversarial ones — which makes the gap priceable. A seller who has quantified what an asset sale costs can ask to be paid for accepting it.
- 2Deferred consideration is not the same money later. An earnout is a bet on management you no longer control, and an installment note is a loan to the person now holding your collateral.
- 3Every term in a purchase agreement has a dollar value, and most of them are set at the letter of intent. Sellers lose money not by negotiating badly but by not knowing which clauses were the expensive ones.
Selling the assets or selling the company
The buyer wants an asset sale for the basis step-up and the liabilities left behind, you want a stock sale, and the gap between them is priceable.
Structure decides how much of the price you keep, and every piece of it is negotiated — most of it at the letter of intent. By the time the definitive agreement is marked up, the expensive decisions are already made.
The specific application belongs to your CPA and your deal attorney. What follows is the map — what to ask, and what a concession is likely to cost.
In an asset sale the buyer purchases the assets and assumes specified liabilities, leaving your entity behind as a shell holding the proceeds. In a stock sale the buyer purchases your equity and the company continues with everything in it — contracts, permits, and every liability, known and unknown.
| Issue | What the buyer gets in an asset sale | What the seller gets in a stock sale |
|---|---|---|
| Tax basis | Stepped-up basis in the acquired assets, generating future depreciation and amortization deductions — worth real money, which is why they will pay for it. | No allocation exercise. The gain is generally treated as sale of a capital asset — usually a better character of income. |
| Liabilities | Only the liabilities they agree to assume. Unknown claims generally stay behind with the seller. | Liabilities transfer with the entity, so the buyer demands broader representations, a larger escrow, and longer indemnity survival. |
| Contracts and permits | Must be assigned, which can require third-party consent — and every consent lets a customer or landlord renegotiate. | Generally continue undisturbed. Change-of-control clauses are the exception and need to be found early. |
| Ordinary income exposure | Not their problem. | Avoids depreciation recapture and other ordinary-income allocations an asset sale can produce. |
Price is what resolves it. A seller accepting an asset sale is accepting a worse tax outcome and should be paid for it — the gap is quantifiable, which is why your CPA belongs in the conversation before the LOI. There are also hybrid mechanisms that let a stock purchase be treated as an asset purchase for tax purposes, so ask whether one applies.
How the price gets divided up
Allocation across asset classes sets the character of your income, and both sides must report it the same way, so it is a real negotiation.
Once an asset sale is agreed, the negotiation moves to allocation — how the total price is divided across categories of assets. This is not paperwork: each category carries a different character of income for you and a different recovery period for the buyer, so your preferences are opposed almost everywhere.
What kind of company you own
A C corporation selling assets can be taxed twice where a pass-through is taxed once, and fixing that takes lead time because the rules carry look-back periods.
A pass-through — S corporation, partnership, or LLC taxed as either — generally produces one layer of tax, at the owner level, on a sale of assets. A C corporation selling assets is taxed at the corporate level and again when proceeds are distributed — the double-tax problem, and the reason a C-corp owner’s preference is usually a stock sale.
Converting entity type is possible; converting and then selling shortly afterward can trigger rules built to prevent that, and those rules have look-back periods. An owner who learns their entity is wrong during LOI negotiation has learned it too late — which is why entity structure belongs in When to Start, not on the closing checklist.
Money you do not get at closing
Installment notes, earnouts, and rollover equity each solve a problem for the buyer and hand you a different risk — none of it is the same money later.
Installment sales let you recognize gain as payments arrive rather than all at once, which can keep proceeds from bunching into one year and smooth the rate on them. The obligation is a receivable from the buyer, often unsecured or secured only by the business you just handed over. If the buyer falters you have a credit problem and a tax problem at once — the gain you already reported does not un-report itself. Mechanics around interest and, for larger obligations, additional charges all need current verification.
Earnouts tie part of the price to post-closing performance — risk transfer dressed as upside, and a bet on someone else’s management. You will not control pricing, capital spending, overhead allocation, or the accounting policies behind the metric you are paid on. If the metric is EBITDA, the buyer’s allocations can reduce it for reasons unrelated to performance; if it is revenue, they can hit it while destroying margin. Earnouts are sometimes necessary, but treat that portion as worth materially less than face value, insist on defined accounting methods and audit rights, and never plan your retirement around it.
Rollover equity makes part of your consideration a stake in the acquirer rather than cash — it aligns you with the buyer and can defer tax on that portion. It also leaves a slice of your net worth in an illiquid minority interest you no longer control, governed by an operating agreement whose terms on distributions, capital calls, drag-along rights, and exit timing you should read personally.
What the buyer holds back
Escrow and a negotiated working capital peg both move real money after closing, and the term that matters most is whether the escrow caps your liability.
Escrow and indemnity holdbacks give the buyer a source of recovery if your representations turn out to be wrong — an undisclosed liability, a tax exposure, a customer dispute that predates closing. The negotiation is about size, duration, and what claims can reach it.
The working capital adjustment surprises almost every first-time seller. Buyers price the business assuming it comes with a normal amount of working capital — receivables, inventory, and payables in their usual balance — so the agreement sets a target, often called a peg, and the price adjusts against the actual number at closing. Both the peg and the definition of what counts are negotiated, long after the headline number is set.
Owner dependence lowers your price and creates the factual basis for a personal goodwill argument at the same time. The analysis is contested enough to need a deal attorney and CPA who have done it before, and it generally requires that you not have already assigned those relationships to the company by contract.
Tax rules to ask about by name
QSBS and the other provisions in play turn on facts and figures that change, so name them to your CPA and get answers in writing before the LOI.
Section 1202 — qualified small business stock, or QSBS — can exclude a portion of the gain on the sale of eligible C corporation stock from federal tax, which makes it one of the most valuable provisions available to a seller when it applies. It carries a long list of requirements: entity type, how and when the stock was acquired, asset thresholds, holding periods, and per-issuer limits. Every one has numbers attached, several have changed, and I am stating none here. If you ever held C corporation stock, put QSBS on the list your CPA confirms in writing, early — some tests depend on facts from the year it was issued.
The same discipline applies to the other provisions: installment method rules, Section 1031 for any real estate in the transaction, opportunity zone reinvestment for the gain, and state-level treatment, which can differ from federal in ways that make residency and apportionment worth real analysis. Ask by name, and get answers before the LOI.
A seller who does not know what a term costs gives it away for free — usually late, when everyone is tired and the clause sounds administrative. Decide in advance which terms you will trade, and treat the tax structure as part of the price rather than paperwork that follows it. For the tax consequences on their own, capital gains and the tax mitigation book carry the rest.
Common questions
- Why does the buyer care so much about an asset sale?
- Two reasons: a stepped-up basis in the assets that generates future depreciation and amortization deductions, and the ability to leave unknown liabilities behind. Both are worth real money to them, which is why the structure is negotiable rather than fixed. Your CPA can quantify what accepting it costs you, and that number becomes a price adjustment you ask for.
- Should I ever accept an earnout?
- Sometimes — an earnout can bridge a genuine disagreement about the value of recent growth, and refusing all contingent consideration can cost you a deal. Accept it assuming it is worth less than face value, with defined accounting methods and audit rights in the agreement, and with your own financial plan built as if it will not pay. If the plan only works when the earnout pays, the deal is worse than it looks.
- Does Main Street Alternatives give tax advice on the deal?
- No. Structuring and the tax positions taken on your return belong to your CPA and deal attorney. We model the after-tax outcome of the structures under discussion so you can see what each one delivers net and on what timeline, and we coordinate so that conversation happens before the letter of intent instead of after.
- What is the single most overlooked term for a first-time seller?
- The working capital adjustment, by a wide margin. It arrives after closing, it is computed from negotiated definitions most sellers never read closely, and it can move a large amount of money in either direction. Second place goes to whether the escrow caps your indemnity exposure or merely delays it.
