Asset Sale vs. Stock Sale: A Plain-English Guide for Small Business Owners (and Why 338(h)(10) Matters)

If you are talking to a buyer about selling your business, you have probably already heard the words "asset deal" and "stock deal." One of those structures will be in your purchase agreement. Most owners do not realize that the choice is one of the most consequential tax decisions in the entire transaction, often worth more than the price negotiation that gets all the attention.

This article walks through what these two structures actually are, why buyers and sellers want different things, and where Section 338(h)(10) fits in. It is written for the owner who is hearing these terms for the first time, not for the tax professional. There are some Code section names along the way, but the goal is to leave you understanding what is happening to your money.

The Box and the Stuff Inside the Box

Every business is two things at once. There is the legal entity (the LLC, the S-corp, the corporation) and there are the assets the entity owns (the equipment, the inventory, the customer list, the goodwill, the lease, the contracts).

Picture the entity as a box. Picture the assets as the stuff inside the box. When a buyer offers to buy your business, the buyer can either buy the box (everything inside, plus the box itself, plus everything that came along with the box over the years) or just buy the stuff inside the box and leave the box behind.

Buying the box is a stock sale (or in an LLC, a sale of membership interests). Buying just the stuff is an asset sale. That single choice determines who pays what kind of tax, who inherits the history of the business, and who gets the future depreciation deductions.

Who Pays the Tax

In a stock sale, you sell your shares in the entity. You recognize gain on the difference between what you paid for the shares (your basis) and what the buyer pays you. That gain is generally long-term capital gain at federal rates of 20 percent plus 3.8 percent net investment income tax for high earners. One transaction. One tax.

In an asset sale, the entity sells each asset, one by one. Each asset has its own tax basis and its own character. Equipment that was depreciated triggers depreciation recapture, which is taxed as ordinary income (up to 37 percent federally) rather than capital gain. Inventory is ordinary income. Accounts receivable, if you are on the cash basis, are ordinary income. Goodwill that you built yourself over the years is generally capital gain. Real estate has its own recapture rules. The asset-by-asset breakdown matters because the blended tax rate is almost always higher than the clean 23.8 percent capital gains rate of a stock sale.

The headline result: for the seller, a stock sale almost always produces a lower tax bill than an asset sale on the same dollar amount. That is why sellers usually want stock deals.

Who Inherits the Liabilities

When the buyer buys the box, the buyer inherits everything that came inside the box. The lawsuits the company has, or the lawsuits the company does not know it has yet. The unpaid sales tax in three states the company never registered in. The misclassified contractor who is going to file a wage claim two years from now. The IRS audit that has not been scheduled but is coming.

When the buyer buys just the stuff inside the box, the buyer typically takes on only the liabilities they specifically agreed to assume. Everything else stays in the box, and the box (with all of its history) stays with the seller.

This is the single biggest reason buyers want asset deals. They are not buying a clean operating business. They are buying a clean operating business and a black hole of unknown legacy exposure. Asset structure lets them filter the box.

The Basis Step-Up: The Buyer's Real Prize

The other reason buyers prefer asset deals is even more valuable than the liability filter, but it is the part most owners do not see coming.

When the buyer pays $5 million for your assets, the buyer's tax basis in those assets resets to $5 million. The buyer can then depreciate equipment, amortize goodwill (over 15 years under Section 197), and write off other purchased assets against future income for years. That is real money. On a $5 million purchase price, the present-value tax savings of a step-up can easily be $700,000 to $1,200,000 over the depreciation life.

In a plain stock sale, the buyer steps into the entity at the entity's existing basis, which after years of depreciation is usually a small fraction of fair value. The buyer pays $5 million but gets to depreciate $400,000. Most of the tax shield is lost.

Buyers value the step-up so highly that they will often pay a higher price to get it. That is the lever that makes Section 338(h)(10) work, which we will get to in a minute.

The C-Corp Double-Tax Trap

If your business is a C-corp (not an S-corp, not an LLC, but a regular C-corp filing Form 1120), an asset sale gets brutal in a way that does not apply to other entity types.

When a C-corp sells assets, the corporation pays tax at 21 percent on the gain. Then, when the corporation distributes the after-tax proceeds to the owner, the owner pays tax again, this time at dividend or capital gain rates plus 3.8 percent NIIT. Run the math: a $10 million asset sale by a C-corp can leave the owner with about $5 million in their pocket. The same $10 million sold as stock would leave the owner with about $7.6 million.

This is why C-corp owners almost always want stock deals, and why C-corp buyers almost always want asset deals. The conflict is structural, not negotiable. If you own a C-corp and you are thinking about selling, this is the conversation to have with a tax advisor years before market, not weeks before signing.

Section 338(h)(10): The Compromise That Often Works

If the seller wants the stock-sale tax treatment and the buyer wants the asset-sale basis step-up, there is a way to give each side what they want. It is called a Section 338(h)(10) election.

A 338(h)(10) election is a joint tax election the buyer and seller file. Legally, the deal is a stock purchase. The buyer buys the shares of the company, the legal title to assets stays in the company, contracts and leases do not need to be reassigned. But for federal tax purposes, the IRS treats the transaction as if the buyer had bought the assets. The buyer gets the asset-sale basis step-up. The seller is taxed as if they had sold assets.

The election only works in specific situations. The target generally has to be an S-corporation or a corporate subsidiary in a consolidated group. The buyer has to be a corporation. The buyer has to acquire at least 80 percent of the vote and value within twelve months. Both sides have to consent on Form 8023.

Here is the part owners usually miss. The seller's tax bill goes up under a 338(h)(10) election. Recapture flips ordinary, state tax sourcing changes, and the blended rate climbs. So sellers do not agree to a 338(h)(10) for free. They demand a "gross-up," which is extra purchase price designed to cover the additional tax cost so the seller's after-tax outcome matches what they would have netted on a clean stock sale.

When everyone runs the math, the gross-up is usually smaller than the value of the buyer's basis step-up. That is why the election is so common. Both sides end up better than they would have on a pure stock sale or a pure asset sale.

A Concrete Example

To make this less abstract, here is the same $10 million sale of an S-corporation under three different structures. The numbers are illustrative and round, not legal advice for any specific situation.

Structure A, asset sale. Sale price $10 million. Asset tax basis $2 million, of which $1 million is recapture (ordinary income) and $1 million is goodwill the seller built (capital gain). The seller's federal tax comes to roughly $2 million ($370,000 ordinary plus $1.66 million capital). Net to seller after federal tax: about $8.0 million.

Structure B, stock sale, no election. Sale price $10 million. Stock basis $2 million. The full $8 million of gain is long-term capital, taxed at about 23.8 percent federally. Federal tax: roughly $1.9 million. Net to seller: about $8.1 million. The buyer hates this structure because they get no step-up and inherit all of the company's history.

Structure C, stock sale with 338(h)(10) election and gross-up. The buyer wants the step-up and offers $10.3 million instead of $10 million to cover the seller's extra tax cost. The seller's tax math now mirrors Structure A but on $10.3 million, leaving roughly the same $8.1 million net. The buyer gets a $10.3 million stepped-up basis to depreciate and amortize, worth roughly $2 million in present-value tax savings. Both sides end up better than they would have under Structure B.

The lesson is not that 338(h)(10) is always the right answer. The lesson is that the structure of the deal determines who captures the value of the basis step-up, and that value is real, often worth more than the headline price negotiation.

F-Reorganization: The Modern Alternative

If you have been selling an S-corporation in the past few years, you may also have heard the term "F-reorg." An F-reorganization (named after subsection (a)(1)(F) of Section 368) achieves a similar tax result to a 338(h)(10) but with more flexibility.

In an F-reorg, the existing S-corp owners drop their company into a newly formed S-corp holding company before closing. The operating business is then converted to an LLC. The buyer purchases the LLC interests, which is treated as an asset purchase for tax purposes. Same result as a 338(h)(10) for both sides, with several advantages: it works when the buyer is an LLC or a private equity fund (which most are), it allows tax-deferred rollover equity for the seller, and it sidesteps the risk that an old defective S-election will blow up the basis step-up.

If your buyer is a private equity firm, the F-reorg is usually the structure you will end up in. It has quietly displaced the 338(h)(10) as the default in middle-market deals. If you do not know which one applies to your situation, that is a sign to talk to a tax advisor before you sign a letter of intent.

Common Misconceptions Owners Bring to These Deals

Selling LLC interests is not automatically clean. If you own a single-member LLC and you sell your interests, the IRS treats that as a deemed asset sale (Revenue Ruling 99-5). Owners assume that selling "the LLC" is a stock-style transaction. It is not.

Capital gains rates do not cover everything. Recapture is ordinary income. Inventory is ordinary income. Receivables are often ordinary income. Saying "I will pay 20 percent" on the sale is a planning error that I see regularly.

338(h)(10) is not free for the buyer. The buyer pays for the basis step-up through the price gross-up. The negotiation is over how much, not whether.

An S-election made years ago is not always still valid. If the company added a shareholder who was not eligible (a corporation, a partnership, a non-resident alien), if the company has a buy-sell agreement that creates a second class of stock, or if the trust elections were not properly maintained, the S-election may have been silently invalid for years. That problem surfaces in diligence and can void the entire 338(h)(10) step-up. Sellers should pressure-test the S-election before going to market.

A stock sale is not a clean exit. Buyer indemnification provisions, escrow holds, and representations and warranties insurance can claw money back from the seller for a year or longer after closing. The deal is not over when the wire hits.

What to Do Before You Sign Anything

If you are six months or more from going to market, model the after-tax outcome under each structure now, before a buyer is on the table. The numbers tell you what you should be willing to negotiate for and what you can give away.

If you have a letter of intent or term sheet in front of you, do not sign it before a tax advisor reads it. The structure and the price interact, and the LOI usually locks in the structure even if it does not feel like a binding document.

If your buyer is a private equity firm, an LLC, or a fund of any kind, ask whether an F-reorganization makes sense for your situation. If the buyer's lawyer brushes the question aside, that is a reason to slow down, not to speed up.

If your business is a C-corp, you have planning to do that takes years, not months. Conversion to an S-corporation, restructuring, or specific buyer-side concessions may all be on the table, but they take time to set up and benefit from.

Closing Thought

The price you accept and the structure you accept are not the same decision. A buyer who wins the structure negotiation can pay a higher headline price and still come out ahead, while the seller can end up with less in their pocket than they would have at a lower price under a different structure. Owners who only negotiate the price and not the structure are leaving real money on the table.
