In almost every sale of a closely held business, the first real disagreement is not about the price. It is about what is being sold. The buyer's letter of intent says it will purchase the assets of the business. The seller's advisor responds that the owners will sell their stock. Each side treats its position as standard, and each is right that it is standard for its side, because the two structures move tax and liability in opposite directions.
My view, after a lot of these negotiations, is that the form of the deal is a price term and should be negotiated as one. A buyer who insists on an asset purchase is asking the seller for something that has a measurable cost to the seller and a measurable value to the buyer, and the right answer is almost never decided by who digs in harder. It is decided by running the numbers for both sides and then pricing the difference. For a C corporation that difference can be enormous; for an S corporation or an LLC it is often small enough to bridge with the right election or structure. And in California, several of the issues that matter most (employees, sales tax, noncompetes, licenses) do not care about the tax answer at all.
The two deals, in plain terms
In a stock sale (or, for an LLC, a sale of membership interests), the owners sell their ownership of the company to the buyer. The company itself does not change. It keeps its contracts, its employees, its licenses, its bank accounts, its tax history, and every liability it has ever incurred, known or unknown. The buyer now owns all of that.
In an asset sale, the company sells its assets (equipment, inventory, customer lists, contracts, intellectual property, goodwill) to the buyer, usually a new entity the buyer has formed for the purpose. The selling company keeps whatever the buyer does not agree to take, which typically includes its historic liabilities, and then pays its own debts and distributes what is left to its owners.
Those two descriptions explain most of the negotiation. A buyer in an asset deal chooses what it takes. A buyer in a stock deal takes everything and relies on the purchase agreement to protect it from what it does not want.
Why buyers want assets
Buyers prefer asset purchases for two reasons, and the tax reason is usually the bigger one.
The tax reason is basis. When a buyer purchases assets, it takes a new tax basis in them equal to what it paid. The part of the price allocated to equipment can be depreciated, often quickly. The part allocated to goodwill and other intangibles (which in a service business is most of the price) is amortized over fifteen years. Every dollar of that deduction reduces the buyer's taxable income. In a stock purchase, the buyer gets none of it: the company keeps its old, usually low, basis in its assets, and the buyer's basis in its stock produces no deductions at all until the buyer sells again.
On a $10,000,000 purchase where most of the price is goodwill, the present value of those deductions to a buyer paying combined federal and California tax can easily run into the high six figures or more. Buyers know this, and their financial models assume it.
The liability reason is selection. In an asset deal, the buyer can leave behind the lawsuit that has not been filed yet, the employee claim from three years ago, the sales tax audit nobody saw coming, and the contract it does not want. In a stock deal, all of that comes along, and the buyer's protection is only as good as the seller's representations and its ability to collect on the indemnity.
Why sellers want stock
Sellers prefer stock sales for the mirror-image reasons. A stock sale is usually taxed once, at capital gain rates for federal purposes. The liabilities leave with the company. And the mechanics are simpler: the owners sign one agreement and transfer their shares, instead of the company assigning dozens of contracts, re-papering employees, and transferring licenses one at a time.
How much the tax difference matters depends almost entirely on what kind of entity is being sold.
The C corporation problem
For a C corporation, the gap between the two structures is large enough to change the deal.
In an asset sale, the corporation sells its assets and pays corporate tax on the gain: 21% federal and 8.84% California. Then the corporation distributes the after-tax proceeds to its shareholders in liquidation, and the shareholders pay tax again on what they receive. California taxes that second gain as ordinary income at rates up to 13.3%, and the federal rate on the capital gain is 20%, plus the 3.8% net investment income tax.
Consider a corporation with assets that have a tax basis of $1,000,000, owned by a shareholder whose basis in the stock is $500,000, selling for $10,000,000. In an asset sale, the corporation's $9,000,000 gain produces roughly $2,520,000 in combined corporate tax. The shareholder receives about $7,480,000 in liquidation and pays roughly $2,590,000 on that, netting about $4,890,000. In a stock sale of the same business at the same price, the shareholder pays tax once, roughly $3,525,000 on a $9,500,000 gain, and nets about $6,475,000.
That is a difference of roughly $1,585,000 to the seller, on the same headline price. No seller should agree to an asset structure for a C corporation without either a price increase that covers a meaningful part of that gap or a specific reason the buyer cannot do the deal any other way.
There is one significant tool for C corporation sellers who are stuck with an asset deal. If the value of the business is really attributable to the owner personally (his or her relationships, reputation and skill, rather than the company's systems and contracts), part of the price can sometimes be paid directly to the owner for that personal goodwill, which is taxed once. It only works when the facts support it: the owner cannot already have an employment agreement or noncompete that gave the goodwill to the company, and the allocation has to be defensible on audit. When it fits, it can recover a substantial part of the double tax.
S corporations: closer than they look
For an S corporation, the gap is usually much smaller, because an S corporation's gain passes through to its shareholders and is taxed once whether the deal is structured as assets or stock. The differences that remain are about character and a few California costs.
In an asset sale, part of the gain may be ordinary income rather than capital gain, most often depreciation recapture on equipment that has been written off. For federal purposes that can cost the seller the difference between a 37% ordinary rate and a 20% capital gain rate on that portion. California also imposes its 1.5% S corporation franchise tax on the corporation's income, including the gain on an asset sale, so a $9,000,000 gain produces roughly $135,000 of entity-level California tax that a stock sale would avoid. And an S corporation that converted from a C corporation within the last five years may still owe corporate-level tax on built-in gains.
Because the remaining gap is modest, S corporation deals are often resolved with an election rather than a fight. Under Section 338(h)(10) or Section 336(e) (where the buyer and the deal qualify), the parties can treat a stock sale as an asset sale for tax purposes: the buyer gets its stepped-up basis, the seller is taxed as if the company had sold its assets, and legally the buyer still acquires the company with its contracts and licenses intact. The seller should be compensated for whatever additional tax the election costs, and the seller's CPA should calculate that number before the letter of intent is signed, not after.
The structure that has become most common for S corporation sales is a pre-sale F reorganization. The shareholders form a new holding corporation, contribute their stock in the old corporation to it, elect to treat the old corporation as a subsidiary, and convert the old corporation into an LLC. The buyer then purchases the LLC interests. For tax purposes, that is an asset purchase, so the buyer gets its step-up; legally, the operating company (with its contracts, employees and permits) continues without interruption; and the S election is preserved through the holding company. It also makes it easy for the sellers to roll over part of their equity into the buyer's structure on a tax-deferred basis, which buyers increasingly ask for.
LLCs and partnerships
For an LLC taxed as a partnership, the distinction between assets and interests mostly collapses for tax purposes. When the buyer purchases the LLC interests, the LLC can make an election that gives the buyer a stepped-up basis in its share of the LLC's assets, so the buyer gets substantially what it would have gotten in an asset deal. The seller is taxed on a sale of a partnership interest, which is capital gain except to the extent of the LLC's "hot assets" (receivables and recapture items), which produce ordinary income in either structure.
A single-member LLC that is disregarded for tax purposes is even simpler: a sale of 100% of its interests is treated as a sale of its assets. In both cases, the negotiation can focus on liability and mechanics, because the tax answer is roughly the same either way.
How the price is allocated
In any deal taxed as an asset sale, the price has to be allocated among the assets, and the buyer and seller report that allocation to the IRS on matching forms. The allocation is a negotiation in its own right, because each category is taxed differently to each side.
The seller wants as much of the price as possible in goodwill, which is capital gain, and as little as possible in equipment recapture, a noncompete, or a consulting agreement, all of which are ordinary income. The buyer wants as much as possible in equipment it can depreciate quickly, and is indifferent between goodwill and a noncompete, since both are amortized over fifteen years. Payments to the owner under a post-closing employment or consulting agreement are deductible to the buyer immediately and fully taxable to the owner as compensation, which is why buyers like to move price into them and sellers should resist.
California adds a wrinkle that makes the federal allocation more important, not less. California has no preferential rate for capital gains; it taxes all of the gain at ordinary rates. So for a California seller, the character of the gain matters at the federal level only, and the allocation fight is really about the federal spread between 20% and 37%.
Qualified small business stock, and California's exception
Owners of C corporations should ask one more question before agreeing to anything: does the stock qualify as qualified small business stock under Section 1202? For qualifying stock, federal law excludes some or all of the gain on a stock sale. For stock issued after July 4, 2025, the exclusion is 50% after three years, 75% after four, and 100% after five, up to a cap of $15,000,000 of gain per issuer (or ten times the shareholder's basis, if greater), for companies whose gross assets did not exceed $75,000,000 when the stock was issued. Older stock follows the earlier rules, which generally require a five-year holding period.
When it applies, it is the strongest argument a seller has for a stock deal, because an asset sale forfeits it entirely. But California does not conform. A California resident who excludes the entire gain federally still pays California tax on all of it at up to 13.3%. That does not make the exclusion less valuable federally, but it does mean California sellers should not model a "tax-free" sale.
The California issues that do not care about tax
Whatever the tax answer, several California rules apply differently depending on the structure, and some of them can drive the decision on their own.
Sales tax and successor liability. In an asset sale, the sale of furniture, fixtures and equipment by a business that holds a seller's permit is generally subject to California sales tax, which someone has to pay. More important, a buyer of a business is required to withhold enough of the purchase price to cover the seller's unpaid sales tax until the seller produces a clearance from the California Department of Tax and Fee Administration. A buyer who does not withhold becomes personally liable for that tax, up to the purchase price. Holding the money in escrow is not enough by itself; the buyer needs the clearance or the withholding. Similar successor rules apply to unpaid payroll taxes owed to the EDD.
Bulk sale rules. California is one of the few states that still has a bulk sale law. For a business whose principal business is selling inventory (retail, wholesale, restaurants and bars), an asset sale outside the ordinary course of business generally requires a recorded and published notice to the seller's creditors before closing, and in many of those deals the price must be paid through an escrow that is responsible for paying creditors' claims. Skipping the notice exposes the buyer to the seller's creditors. Service businesses are generally outside the statute, but the sales tax and payroll tax successor rules above still apply.
Employees. In an asset sale, the seller's employees are terminated by the seller and hired by the buyer. California requires that final wages, including all accrued and unused vacation (which California does not allow to be forfeited), be paid on the last day of employment, which in an asset sale is usually the closing date. A business with seventy-five or more employees may also trigger California's WARN Act notice requirements. In a stock sale, the employer does not change and none of that happens.
Contracts, leases and licenses. An asset sale requires the seller to assign its contracts, and many contracts (commercial leases above all) require the landlord's or counterparty's consent. Some licenses and permits cannot be assigned at all and must be reissued to the buyer, which for an alcoholic beverage license or a health care license can take months. A stock sale avoids assignment, but many contracts contain change-of-control clauses that require consent anyway, so the diligence has to be done either way.
Real property. If the business owns real estate, an asset sale reassesses it for property tax. A stock sale reassesses it too if the buyer acquires more than 50% of the company, which in a sale of the business it almost always does, and the change in control has to be reported to the State Board of Equalization within 90 days. (We covered those rules in more detail in our article on holding California rental property.) The structure rarely saves property tax, but forgetting the filing in a stock deal is an expensive mistake.
The noncompete
California law voids almost every agreement that restrains anyone from engaging in a lawful business, and in recent years the Legislature has made the prohibition stronger and given employees the right to sue over unlawful noncompetes. The one significant exception is for the sale of a business. A person who sells the goodwill of a business, or who sells all of his or her ownership interest in a company, or who is an owner of a company that sells substantially all of its operating assets together with its goodwill, may agree not to compete within the area where the business was carried on, for as long as the buyer carries on a like business there.
The structure of the deal determines who qualifies. In a stock sale, an owner who sells only part of his or her interest (for example, because the buyer requires a rollover) needs to fit within the statute's language, and the drafting has to track it. Key employees who are not selling owners cannot be bound by a noncompete at all, no matter how much the buyer would like that, so the buyer's protection for those relationships has to come from retention arrangements, trade secret protections and a reasonable non-solicitation of customers rather than a covenant California will not enforce. Buyers coming from other states are frequently surprised by this, and it is better to address it in the letter of intent than at the closing table.
Protecting a buyer in a stock deal
When a seller wins the argument for a stock sale, the buyer's protection moves into the purchase agreement. The usual tools are detailed representations and warranties about the company's taxes, employees, contracts, litigation and compliance; an indemnity for breaches of those representations and for specified known issues; and a portion of the price held back in escrow for twelve to twenty-four months to secure the indemnity. In larger deals, representations and warranties insurance can replace much of the escrow, which sellers prefer because they receive more of the price at closing.
From the seller's side, the negotiation is about limits: a cap on the indemnity (often a percentage of the price), a deductible or threshold before claims can be made, a survival period after which claims expire, and a narrow definition of the losses covered. A seller who wins the stock sale and then gives an uncapped indemnity has not won very much.
Bridging the gap
Once both sides have run the numbers, most deals resolve with one or more of a short list of tools. The buyer can pay a higher price for an asset deal, sized to the seller's additional tax, which still leaves the buyer ahead when the value of its tax deductions exceeds the increase. For S corporations, a Section 338(h)(10) or 336(e) election, or a pre-sale F reorganization, can give the buyer its step-up while the seller keeps a clean legal exit. For C corporations, a personal goodwill sale can recover part of the double tax when the facts support it. And deferred consideration (an earnout tied to post-closing performance, or seller financing reported on the installment method) can spread the seller's tax and close a valuation gap at the same time, at the cost of leaving the seller dependent on the buyer's performance.
How I approach it
When a client is selling a business, I want the structure analysis done before the letter of intent is signed, because the letter of intent is where the structure is usually agreed and the leverage to change it later is limited.
That means confirming how the company is taxed and whether there is any built-in gain or qualified small business stock history; having the client's CPA run the after-tax proceeds under each structure the buyer might propose; identifying the California issues that will apply regardless (employees, sales tax clearance, bulk sale notice, licenses, leases, real property); and deciding in advance what the seller needs to be paid to accept an asset deal. When we represent a buyer, we do the same analysis from the other side, because a buyer who understands the seller's tax position can often offer a structure that costs the seller less and still gives the buyer most of what it wants.
The form of the deal is not a formality. It is often worth more than the last round of price negotiation, and it should be settled with the same care.
If you are thinking about selling your business in the next few years, or you have a letter of intent in front of you now, it is worth an hour to see what each structure would actually put in your pocket. We would be glad to schedule a consultation.
