Most M&A conversations focus on valuation multiples. The structure conversation — asset sale versus stock sale — often arrives late, gets compressed into a single advisor meeting, and then quietly determines how much of the purchase price the seller actually keeps. The delta is not marginal. On a $10M transaction, structural choice alone can shift after-tax proceeds by $1.5M to $2.5M, sometimes more, depending on entity type and asset composition.

Why Buyers Default to Asset Sales

The buyer’s preference for an asset purchase is straightforward: they receive a stepped-up cost basis on acquired assets, which generates depreciation and amortization deductions against future income. On a deal with significant goodwill or equipment, that tax shield has real present value — often enough that sophisticated buyers will price it explicitly into their offer. The buyer is not being generous when they agree to pay a slight premium in an asset deal; they are often recovering that premium through post-close tax benefit within three to five years.

For the seller, the asset sale structure typically triggers ordinary income rates on certain asset categories — inventory, receivables, and depreciation recapture on fixed assets under IRC Section 1245 and 1250. Only the portion allocated to goodwill benefits from long-term capital gains treatment, and allocation negotiations between buyer and seller on Form 8594 can become their own sub-negotiation entirely.

The Stock Sale Argument and Its Friction

In a stock sale, the seller transfers equity rather than underlying assets. The entire gain is generally treated as a capital gain, which at current federal rates represents a meaningful structural advantage for sellers who have held their interest longer than twelve months. For S-corp and C-corp sellers, the distinction is particularly pronounced. C-corp sellers face double taxation in an asset sale — tax at the corporate level on asset gains, then again at the shareholder level on distribution — making stock sale structure significantly more defensible on pure economics.

Buyers resist stock sales for two reasons: inherited liabilities and the loss of that stepped-up basis. Unknown liabilities — pending litigation, tax exposures, employee claims — transfer with the stock. Buyers price that uncertainty into their offers, often demanding representations, escrow holdbacks, or rep-and-warranty insurance, all of which compress net proceeds in their own ways.

Where Advisors Diverge

The disagreement among deal advisors is less about the economics — those are largely calculable — and more about negotiating sequencing. Transaction attorneys often push to resolve structure early, before LOI, because it affects every downstream term. M&A brokers and intermediaries sometimes defer it, preferring to secure headline price agreement first and treat structure as a secondary negotiation. Neither approach is categorically wrong, but deferring the structural conversation does create risk that buyer and seller have anchored to a price that doesn’t survive the after-tax modeling.

• 338(h)(10) and 336(e) elections allow certain acquisitions of S-corps and subsidiaries to be treated as asset sales for tax purposes while maintaining the legal form of a stock sale — a partial bridge between buyer and seller interests.
• Allocation of purchase price across asset classes under IRC Section 1060 follows a prescribed ordering that neither party fully controls once structure is set.
• State tax treatment adds another layer; several states do not conform to federal capital gains rates, narrowing the stock sale advantage in certain jurisdictions.

The Operator Read

Sellers who engage their CPA and transaction counsel before the LOI — not after — tend to enter the structure negotiation with modeled scenarios rather than instincts. The structural choice is not a formality appended to the deal; it is a deal term with direct, calculable impact on net proceeds. Buyers know this. The structural setup consistently favors whichever party arrives to that conversation better prepared.
