Nearly every private-company acquisition contains the same built-in conflict: the buyer wants an asset sale and the seller wants a stock sale, and both are right from where they sit. The buyer wants a stepped-up basis it can depreciate and amortize, plus the ability to leave unknown liabilities behind. The seller wants to be taxed once at capital-gain rates instead of absorbing the double tax that hits a C-corporation asset sale. This isn't a personality clash — it's structural, baked into the tax code, and it drives more deal negotiation than almost any other single issue.
The good news is that the tension is quantifiable. The difference between the two structures can be modeled to the dollar, which means it can be priced. When a seller insists on a stock sale, the buyer can calculate the value of the basis step-up it's giving up and demand a lower price to compensate. When a buyer needs asset treatment on a target that's really a stock deal, the Section 338(h)(10) election can bridge the gap. Knowing the mechanics is what turns an impasse into a negotiated number.
The core tradeoff, side by side
Everything about the asset-vs-stock decision flows from two levers: whether the buyer gets a basis step-up, and how many layers of tax the seller faces. Lay them next to each other and the negotiation writes itself.
Asset sale — buyer's preference
- Buyer gets a stepped-up, depreciable/amortizable basis
- Buyer picks which assets and liabilities to assume
- Unknown and contingent liabilities can be left behind
- Seller may face double tax if it's a C-corporation
- More paperwork — assets and contracts must be retitled/reassigned
Stock sale — seller's preference
- Seller taxed once, generally at capital-gain rates
- Whole entity transfers — contracts, licenses, EIN intact
- Buyer inherits carryover basis — no step-up
- Buyer inherits all liabilities, known and unknown
- Cleaner mechanically, riskier for the buyer on liabilities
Notice the symmetry: almost every point that favors one party costs the other. That's why the structure is rarely a standalone fight — it's really a fight over price, because the tax cost of either structure can be shifted through the purchase price.
Why the basis step-up is worth real money
A stepped-up basis isn't an accounting nicety — it's a stream of future tax deductions. When the buyer's basis equals the price paid, it depreciates the tangible assets and amortizes the intangibles from that higher number, cutting taxable income for years.
| Asset class | Buyer's treatment after a step-up | Recovery period |
|---|---|---|
| Equipment & machinery | Depreciated (often accelerated / bonus-eligible) | Typically 5–7 years |
| Buildings / real property | Depreciated (straight line) | 27.5 or 39 years |
| Goodwill & most intangibles | Amortized under Section 197 | 15 years |
| Inventory | Recovered as cost of goods sold | As sold |
In a carryover-basis stock deal, the buyer gets none of this fresh depreciation and amortization — it inherits the seller's already-depreciated basis. That lost future deduction is exactly what a buyer quantifies when it asks a seller to accept a lower price in exchange for a stock structure.
The double-tax trap that drives sellers to stock deals
The seller's aversion to asset sales is almost entirely about the C-corporation double tax. Sell the assets, and the corporation pays tax on the gain; distribute the proceeds, and shareholders pay again. That second layer can consume a large slice of the seller's proceeds.
The two-layer tax hits C-corporations. Pass-through entities — S-corporations and partnerships/LLCs taxed as partnerships — generally face only one layer even on an asset sale, because the gain flows straight through to the owners. So the seller's structure preference is largely a function of entity type: a C-corp seller fights hard for a stock deal to avoid the double tax, while a pass-through seller can often accept an asset deal without the same penalty. Always confirm the target's tax classification before assuming which structure the seller will demand.
This is why the first question in any deal-structure conversation is "what is the target for tax purposes?" A pass-through target opens the door to an asset deal both sides can live with. A C-corp target usually forces a stock sale — or the election that mimics an asset sale without triggering the double tax the same way.
Section 338(h)(10): getting asset treatment inside a stock deal
When the buyer needs a step-up but the deal must be a stock transfer — often because the target is an S-corporation or a subsidiary with contracts and licenses that shouldn't be disturbed — the Section 338(h)(10) election delivers both.
Verify the target qualifies
The target must generally be an S-corporation or a corporate subsidiary in a consolidated group, and the buyer must be a corporation making a qualified stock purchase.
Elect jointly on Form 8023
Both buyer and seller must sign — neither can make the election alone. The election treats the stock purchase as a deemed sale of the target's assets.
Buyer gets the step-up
The buyer takes a fair-market-value basis in the deemed-acquired assets, unlocking future depreciation and amortization just like a true asset deal.
Model and price the seller's tax
The election taxes the seller as an asset sale, which can be more or less than a plain stock sale. The parties price that delta into the deal so the after-tax economics stay balanced.
Run the 338(h)(10) numbers on both sides before you commit to it. For an S-corporation target with few appreciated ordinary-income assets, the election is often close to tax-neutral for the seller and a clear win for the buyer — an easy yes. But if the deemed asset sale converts a chunk of the seller's gain from capital to ordinary, the seller's extra tax can exceed the buyer's benefit. When it does, the election isn't worth making, and no amount of price adjustment fixes a net loss to the parties combined.
Beyond tax: liabilities and diligence follow the structure
The structure also decides who owns the target's history. In a stock sale, the buyer steps into the entity and inherits everything — including liabilities it hasn't discovered yet. In an asset sale, the buyer can generally cherry-pick, though successor-liability rules mean "generally" is not "always."
- Stock sale — buyer inherits all liabilities, including unknown tax exposure, pending litigation, and warranty claims, making thorough due diligence essential
- Asset sale — buyer typically assumes only the liabilities it names, but successor-liability doctrines can still attach certain obligations (some tax, some employment, some environmental)
- Stock sale — existing contracts, permits, and licenses usually stay in place without reassignment; anti-assignment clauses are avoided
- Asset sale — contracts and licenses may need consent to transfer; anti-assignment clauses can complicate closing
- Either structure — reps, warranties, and indemnities (and often escrow or rep-and-warranty insurance) allocate residual risk the structure doesn't resolve
The asset-vs-stock decision is a solvable equation, not a standoff. Start by confirming the target's tax classification — a C-corp's double-tax exposure usually pushes toward a stock deal, while a pass-through can accept an asset deal. Quantify the buyer's basis step-up as a stream of future deductions and price it into the negotiation. Where the buyer needs asset treatment on a stock deal, model a Section 338(h)(10) election on both sides before electing. And never let the tax structure obscure the liability tradeoff — a stock buyer inherits the entity's whole history, so diligence has to match.

Frequently asked questions
Two reasons. First, the buyer gets a stepped-up basis equal to what it paid, so it can depreciate the equipment and amortize the intangibles going forward — real future tax deductions. Second, in an asset sale the buyer generally chooses which assets and liabilities to take, leaving unknown or contingent liabilities behind with the old entity. Basis step-up plus liability protection is why buyers push for asset deals.
A stock sale is typically taxed once, at long-term capital-gain rates on the gain over the seller's stock basis. A C-corporation asset sale, by contrast, is taxed twice — at the corporate level on the gain and again when proceeds reach shareholders. Sellers also like that a stock sale transfers the whole entity, contracts and licenses included, without retitling every asset.
Stepped-up basis means the buyer's tax basis in the acquired assets equals the price it paid, rather than the seller's old (usually lower, depreciated) basis. A higher basis produces larger depreciation and amortization deductions in future years, lowering the buyer's taxable income. In an asset sale the buyer gets this step-up; in a plain stock sale it does not — it inherits carryover basis.
It lets the parties legally transact in stock while being taxed as if they sold assets. The buyer gets the stepped-up basis it wants, and the seller is taxed as an asset sale. It requires a qualifying target (generally an S-corporation or a corporate subsidiary), a corporate buyer, and a joint election on Form 8023. Because it changes the seller's tax, the parties usually price the difference into the deal.
