When a buyer acquires a business, there are two fundamental ways the transaction can be structured: the buyer can purchase the assets of your company, or the buyer can purchase the equity — the stock or membership interests — of the company itself. This structural choice is not a technicality. It determines what the buyer takes legal ownership of, what liabilities they assume, who bears the risk of unknown historical problems, and, perhaps most significantly, how much of the purchase price you actually keep after the government takes its share. Buyers and sellers often have directly opposing interests on this question, and the negotiation over deal structure is one of the most consequential that takes place in any M&A transaction.

This article explains both structures in plain terms, describes why buyers typically prefer one and sellers the other, and walks through the specific ways that the choice between an asset deal and a stock deal affects taxes, liabilities, and your ultimate financial outcome.

What Is an Asset Sale?

In an asset sale, the buyer purchases specific assets of your company rather than purchasing the company itself. The buyer acquires the things your business owns and uses — equipment, inventory, receivables, intellectual property, customer contracts, trade names, goodwill — and assumes specific, identified liabilities that the parties agree to include in the transaction. Your legal entity — the corporation or LLC that has been operating the business — remains yours after the transaction. It no longer has the business assets or operations inside it, but the legal shell continues to exist, at least until you wind it down.

One of the defining features of an asset sale is that the buyer gets to choose what it buys and what it does not buy. The purchase agreement will contain detailed schedules listing the specific assets being transferred and the specific liabilities being assumed. Everything not listed on those schedules stays with the seller. This selectivity is one of the primary reasons buyers prefer asset deals: they can acquire the productive assets of the business while leaving behind unwanted liabilities, contingent obligations, and historical baggage.

After an asset sale closes, the seller’s legal entity holds the cash proceeds from the sale. If the seller is a C corporation, the corporation must pay corporate income tax on the gain from the sale of the assets. The after-tax proceeds then sit inside the corporation until the shareholders take a distribution, at which point they pay tax again at the individual level on that distribution. This double layer of tax is the central reason founders of C corporations find asset deals unattractive. If the seller is an S corporation or an LLC taxed as a pass-through entity, only one level of tax applies — the gain flows through to the individual owners — which makes the structure less penalizing, though still generally less favorable than a stock sale.

What Is a Stock Sale?

In a stock sale — or a membership interest sale, if the entity is an LLC — the buyer purchases the equity of the company directly from the owners. Rather than buying the assets inside the company, the buyer buys the vehicle that holds those assets. You sell your shares; the buyer becomes the new owner of the same legal entity that has been operating the business all along, with all of its assets, contracts, employees, rights, and liabilities intact.

From the seller’s perspective, a stock sale is clean and direct. You own shares. You sell those shares. The proceeds come to you as an individual, and you pay capital gains tax on the difference between your sale price and your basis in the shares. If you have held the shares for more than one year, the gain qualifies as long-term capital gain and is taxed at rates that are significantly lower than ordinary income rates. For most sellers, this is the most tax-efficient outcome available.

From the buyer’s perspective, a stock sale is far less attractive from a tax standpoint. When a buyer purchases stock, it takes the company’s tax basis in its assets as-is — it does not get to step up the basis of those assets to the purchase price paid. This matters because depreciation and amortization deductions, which generate tax savings over time, are calculated based on the tax basis of the assets. In an asset sale, the buyer gets a stepped-up basis equal to the purchase price allocated to each asset, which means it can depreciate those assets from their full fair market value going forward. In a stock deal, the buyer inherits the company’s historical (often very low) basis in its assets and cannot depreciate them from the purchase price.

Why Buyers Prefer Asset Deals

Buyers prefer asset deals for two primary reasons: liability protection and tax benefits. On the liability side, the ability to cherry-pick assets and exclude liabilities is enormously valuable. When a buyer purchases stock, it acquires everything inside the legal entity — including liabilities that the seller did not disclose, did not know about, or actively concealed. Those might include unpaid taxes, environmental contamination, product liability claims, employment disputes, breaches of contract, or any other obligation that attached to the company during its operating history. In an asset deal, those unknown liabilities stay with the seller’s entity, not the buyer.

On the tax side, the step-up in basis available in an asset deal can generate very significant tax savings for the buyer over the years following the acquisition. When a buyer pays $20 million for a company whose assets have a historical tax basis of $2 million, an asset deal gives the buyer a $20 million basis in those assets — meaning it can depreciate or amortize $20 million over the applicable recovery periods. A stock deal leaves the buyer with only a $2 million basis. The present value of those additional depreciation deductions can be in the millions of dollars, particularly for deals involving significant intangible assets, which under current tax law are amortized over fifteen years.

These advantages explain why, in the absence of any offsetting considerations, most buyers will prefer an asset deal and will price an asset deal higher than a stock deal. Many buyers will explicitly offer a purchase price premium if the seller agrees to structure the transaction as an asset deal, to compensate for the additional taxes the seller will bear. Understanding the magnitude of your tax disadvantage in an asset deal is therefore essential to evaluating whether any premium offered is actually sufficient to make you whole.

Why Sellers Prefer Stock Sales

Sellers prefer stock sales primarily because of tax efficiency, but also because of a cleaner break from historical liability. On the tax side, a stock sale allows individual shareholders to pay tax at long-term capital gains rates on the full gain from the transaction. As of 2024, the federal long-term capital gains rate for most taxpayers is either fifteen or twenty percent, with a 3.8 percent net investment income tax potentially applying as well, for a maximum federal rate of 23.8 percent. This compares favorably to the ordinary income tax rate, which reaches 37 percent at the federal level, and to the double-tax scenario in a C corporation asset deal.

On the liability side, selling your stock means that you transfer the legal entity — and all of its historical obligations — to the buyer. You are no longer the owner of that entity, and in general, historical liabilities that surface after closing are the buyer’s problem as the new owner. Of course, in practice, the purchase agreement will contain representations and warranties under which you promise the buyer that there are no undisclosed liabilities, and you will be obligated to indemnify the buyer if those representations turn out to be false. But the structural liability protection of a stock sale is still meaningfully greater than in an asset deal, where the seller’s entity retains whatever liabilities the buyer declines to assume.

Section 338(h)(10) and F Reorganizations: Bridging the Gap

Because buyers and sellers have opposing preferences, deal structures have evolved to bridge the gap — specifically, to allow the buyer to get the tax benefits of an asset deal while giving the seller the tax treatment of a stock deal. The most important of these mechanisms is the Section 338(h)(10) election, available when the seller is an S corporation and the buyer is a corporation. Under this election, the parties agree to treat a stock sale as if it were an asset sale for tax purposes — the buyer gets a stepped-up basis in the assets, while the tax is calculated at the S corporation’s entity level rather than the C corporation double-tax level. Because S corporation income flows through to individual shareholders, the seller avoids the double-tax problem while the buyer gets the benefit of a step-up.

A similar result can be achieved through a Section 336(e) election in certain other corporate structures, and through the standard tax treatment of an asset deal when the seller is a single-member LLC disregarded for tax purposes. When the seller is a multi-member LLC taxed as a partnership, the sale of membership interests is generally treated as an asset sale for tax purposes under the default rules, which means sellers of partnership interests often face tax treatment that looks more like an asset deal than a stock deal regardless of how the transaction is structured legally.

These nuances make pre-transaction tax planning not merely useful but essential. The optimal structure for any given deal depends on the seller’s entity type, the buyer’s entity type, the respective tax positions of each, and the specific assets involved. Tax counsel should be engaged early in the process — ideally before the LOI is signed — so that structure can be negotiated as part of the commercial deal rather than after the purchase price has already been agreed.

How Structure Affects What You Walk Away With: A Concrete Example

Consider a simple example. A C corporation is being sold for $10 million. The corporation’s tax basis in its assets is approximately $1 million. In an asset deal, the corporation recognizes a $9 million gain on the sale of the assets. After paying federal and state corporate income tax — at, say, a combined rate of approximately 30 percent — the corporation has roughly $7.3 million remaining. The shareholders then take a distribution of those proceeds. If they pay a combined federal and state rate of approximately 25 percent on the distribution (treating it as a qualified dividend), they net approximately $5.5 million. The government has taken almost half the proceeds.

In a stock deal with the same $10 million price, the shareholders pay capital gains tax directly on their gain. Assuming a basis in the stock of approximately zero (as is common for founders) and a combined federal and state capital gains rate of approximately 25 percent, the shareholders net $7.5 million — almost $2 million more than in the asset deal scenario. This is why the choice of structure matters so profoundly, and why founders of C corporations are willing to fight hard for a stock deal structure.

For buyers who insist on an asset deal, the question becomes: what premium is necessary to compensate the seller for the additional tax cost? Computing this number requires a detailed analysis of the specific tax positions involved, which is why transaction tax counsel is indispensable in any serious deal. The answer varies significantly depending on the seller’s entity type, the seller’s basis in their equity, the applicable state tax rates, and the exact allocation of purchase price among asset classes.

Purchase Price Allocation in Asset Deals

In an asset deal, the purchase price must be allocated among the various categories of assets being sold. This allocation — which is reported to the IRS by both buyer and seller on Form 8594 — matters enormously because different asset classes carry different tax consequences. Assets such as inventory and accounts receivable generate ordinary income to the seller upon sale. Equipment and real property may trigger ordinary income to the extent of prior depreciation claimed. Goodwill and going-concern value generate capital gain. The buyer and seller have different incentives in this allocation: sellers want to maximize the portion allocated to capital gain assets like goodwill, while buyers want to maximize the portion allocated to assets with the fastest depreciation schedules. Negotiating the purchase price allocation is a significant part of any asset deal negotiation, and the parties must ultimately agree on a single allocation that both will report consistently to the IRS.

In summary, the choice between an asset sale and a stock sale is one of the most consequential decisions in any M&A transaction. It affects the buyer’s tax position, the seller’s after-tax proceeds, the allocation of historical liabilities, and the complexity of the post-closing relationship. Understanding the trade-offs, securing skilled tax counsel early in the process, and approaching the structure question as an integral part of the price negotiation rather than a downstream detail will give you the best chance of a structure that you can live with and proceeds that reflect the full value of what you have built.
