Buying a Business: Asset Purchase vs. Stock Purchase and Why the Tax Treatment Is Different

A business acquisition can be structured as a purchase of assets, corporate stock, or an ownership interest in an LLC or partnership. Those labels affect tax basis, tax character, liabilities, contracts, elections, and future deductions. The legal and tax classification of the target must be confirmed before comparing structures.

Asset Purchase: The Buyer Acquires Identified Assets and Liabilities

In an asset purchase, the agreement identifies the assets transferred and liabilities assumed. Buyers often prefer this structure because it can limit contractual assumption of unwanted liabilities and provide new tax basis in acquired assets.

An asset purchase does not guarantee that every historical liability remains with the seller. Successor-liability, bulk-sale, fraudulent-transfer, employment, environmental, tax, licensing, and state-law rules can impose obligations despite the contract. Legal due diligence remains necessary.

Purchase-Price Allocation and the Buyer's Basis

In an applicable asset acquisition, the consideration is generally allocated under the Section 1060 residual method. The allocation determines the buyer's basis in inventory, receivables, equipment, land, buildings, identifiable intangibles, goodwill, and going-concern value.

Different classes recover cost differently. Inventory is generally recovered through cost of goods sold. Depreciable assets follow their applicable recovery rules and limitations. Goodwill and many other Section 197 intangibles are generally amortized ratably over 15 years. Land is not depreciable.

The Seller's Tax Character Varies by Asset

An asset sale can produce a mixture of ordinary income, Section 1231 gain or loss, depreciation recapture, unrecaptured Section 1250 gain, and capital gain. The result depends on the asset, holding period, prior depreciation, entity type, accounting method, and allocation.

For a C corporation, an asset sale followed by a distribution or liquidation can create tax at both the corporate and shareholder levels. Pass-through and disregarded sellers generally have different structures, although S corporations can face built-in gains tax and other entity-level issues.

Stock Purchase: The Buyer Acquires the Corporation

In a corporate stock purchase, the corporation continues to own its assets and generally retains their existing tax bases. The buyer receives basis in the acquired stock, not an automatic inside basis step-up in the corporation's assets.

The premium paid above the corporation's inside asset basis is not necessarily “lost.” It is reflected in the buyer's stock basis and may affect gain or loss on a later stock disposition. However, it generally does not create current depreciation or amortization inside the target absent an applicable election or restructuring.

Because the legal entity continues, its contracts, permits, employees, liabilities, tax history, and attributes generally remain with it, subject to change-of-control terms and other restrictions. That continuity can be helpful operationally but increases diligence risk.

The Seller's Stock-Sale Result

A shareholder generally recognizes gain or loss equal to the difference between the amount realized and stock basis. Long-term capital-gain treatment may apply when the holding-period and other requirements are met. Special rules can affect qualified small business stock, collapsible corporations, installment sales, related parties, dealer status, and other transactions.

LLC and Partnership Interest Sales Are Not Automatically Stock Sales

A sale of an interest in a disregarded LLC may be treated as a sale of underlying assets for federal income-tax purposes. A partnership-interest sale generally produces gain or loss on the interest, but Section 751 can recharacterize part of the gain as ordinary income, and a Section 754 election may create an inside basis adjustment for the buyer. A corporate-taxed LLC follows corporate rules.

Deemed Asset-Sale Elections

A qualifying stock acquisition may be treated as an asset acquisition for federal tax purposes through a Section 338 election. A joint Section 338(h)(10) election is available only for specified targets and sellers, generally including certain S corporation targets and subsidiaries sold by qualifying corporate groups. Section 336(e) may provide another deemed-asset-sale election in qualifying transactions.

These elections can give the buyer stepped-up inside asset basis while imposing asset-sale tax consequences on the seller or target. The parties often negotiate price, indemnification, and allocation terms to address the additional tax cost.

Form 8594 and Consistent Reporting

Buyer and seller generally file Form 8594 for an applicable asset acquisition and report the consideration by asset class. The parties should use consistent allocations unless a recognized exception applies and should disclose later changes to consideration when required.

A defensible allocation should reflect the negotiated agreement and supportable fair market values, not merely the tax preference of one party. Tax, legal, valuation, licensing, and financial diligence should occur before the structure and price are finalized.
