Asset purchase or stock purchase: where the federal tax consequences actually diverge

Reviewed 2026-09-15 · AI-assisted draft and editing; sources and limitations remain visible for independent review.

Answer: Deal form changes fewer federal issues than deal summaries suggest, but the ones it changes are structural. Buying assets that constitute a trade or business is usually an applicable asset acquisition under section 1060(c), which forces the buyer's cost and the seller's amount realized through the residual method and onto an asset-by-asset statement. Buying the shares of a corporation instead leaves the corporation's own basis in its assets untouched and puts the buyer's cost into the shares. The second divergence is attributes. Section 381(a) lets an acquiring corporation succeed to the items listed in section 381(c), including net operating loss carryovers, only in a distribution to which section 332 applies or a transfer to which section 361 applies in connection with a reorganization described in subparagraph (A), (C), (D), (F) or (G) of section 368(a)(1). An ordinary taxable purchase of assets is not on that list, while a share purchase leaves the attributes inside the corporation, where section 382 may limit them after an ownership change. The third is documentary: section 1060(a) makes a written allocation agreement binding on the parties unless the Secretary determines it is inappropriate, and Regulations section 1.1060-1(e) puts both sides on Form 8594. Code text read as in effect September 14, 2026; regulations from the edition revised April 1, 2025; Form 8594 instructions revised November 2021.

Assumptions

• The target business is held in a domestic corporation and the buyer pays cash or assumes liabilities rather than issuing its own stock.
• The purchase is taxable; a transaction intended to qualify as a reorganization is analyzed elsewhere.
• The comparison is of federal income tax consequences of the two forms, not of price, risk allocation, or non-tax deal terms.

Exclusions

• State and local tax treatment, successor liability, bulk sale rules, and transfer taxes, all of which are state law.
• A conclusion for any actual transaction, allocation schedule, or filing position.
• Elections under section 338 that recast a share purchase as a deemed asset acquisition, which the sibling page covers.
• Purchases of partnership interests, which have their own reporting rules, and acquisitions of foreign targets.

1. Decide first whether section 1060 is engaged

Section 1060(c) defines an applicable asset acquisition as any transfer, direct or indirect, of assets constituting a trade or business with respect to which the transferee's basis is determined wholly by reference to the consideration paid. Regulations section 1.1060-1(b)(1) adds the detail that matters in practice: the assets need only constitute a trade or business in the hands of either the seller or the purchaser, not both.

Regulations section 1.1060-1(b)(2)(i) supplies two alternative tests for that threshold. A group of assets constitutes a trade or business if the use of the assets would constitute an active trade or business under section 355, or if its character is such that goodwill or going concern value could under any circumstances attach to the group. The second test is deliberately wide, and the Instructions for Form 8594 list the indicators used to apply it, including the presence of section 197 or other intangibles, an excess of total consideration over the aggregate book value of assets other than goodwill and going concern value, and the presence of a license, lease, covenant not to compete, management contract, or employment contract between the parties.

A share purchase does not engage section 1060 at all, because the buyer acquires an interest in an entity rather than a group of assets. That single difference is the source of most of what follows, and it is worth stating explicitly in the file rather than assuming it.

2. The residual-method workpaper an asset deal requires

Section 1060(a) directs that consideration be allocated among the assets in the same manner as amounts are allocated under section 338(b)(5). Regulations section 1.1060-1(c)(2) implements that by sending both parties to the residual method of sections 1.338-6 and 1.338-7, substituting consideration for the aggregate deemed sale price on the seller's side and for the adjusted grossed-up basis on the purchaser's side: the seller uses it to determine the amount realized on each asset, the purchaser to determine basis in each asset.

The Instructions for Form 8594 set out the seven classes the method uses. Class I is cash and general deposit accounts. Class II is actively traded personal property together with certificates of deposit and foreign currency. Class III is assets marked to market at least annually and debt instruments including accounts receivable. Class IV is stock in trade and inventory-type property. Class V is everything not in another class, which is where furniture, fixtures, buildings, land, vehicles, and equipment generally fall. Class VI is section 197 intangibles other than goodwill and going concern value. Class VII is goodwill and going concern value.

Two mechanical rules control the arithmetic. Consideration is reduced by Class I, then allocated to Class II, then III, IV, V and VI in order, within each class in proportion to fair market values on the purchase date, with anything left going to Class VII. The amount allocated to an asset other than a Class VII asset cannot exceed its fair market value on the purchase date, and where an asset could sit in two classes the lower-numbered class controls. The instructions also note that fair market value for this purpose is gross fair market value, unreduced by mortgages, liens, pledges, or other liabilities.

A workpaper that survives review therefore has a row per asset with its class, an independent value support, a column for the running residual, and a note wherever the fair market value cap bites. Building it after the agreement is signed is usually how a disagreement between the parties becomes visible.

3. Test whether the tax attributes travel

Section 381(a) is a closed list. An acquiring corporation succeeds to and takes into account the items described in section 381(c) only in the acquisition of assets of another corporation in a distribution to which section 332 applies, or in a transfer to which section 361 applies but only if the transfer is in connection with a reorganization described in subparagraph (A), (C), (D), (F) or (G) of section 368(a)(1). Section 381(c)(1) is where net operating loss carryovers appear.

An ordinary taxable purchase of assets is not one of those transactions, so the buyer of assets is not taking over the seller's carryovers by operation of section 381. A purchase of shares does not move attributes either, for the opposite reason: nothing leaves the corporation, so its attributes stay where they are, attached to the same taxpayer under new ownership.

That is the hinge that sends a share purchase into a separate analysis. Attributes that remain inside an acquired corporation can be limited after an ownership change, which is the subject of the sibling page titled Corporate NOLs after an ownership change: a section 382 testing checklist. Section 381(b)(1) adds a timing point worth capturing where section 381 does apply: except in the case of a reorganization described in section 368(a)(1)(F), the taxable year of the distributor or transferor corporation ends on the date of the distribution or transfer.

4. What the written allocation agreement actually binds

Section 1060(a) provides that where the transferor and transferee agree in writing as to the allocation of any consideration, or as to the fair market value of any of the assets, that agreement is binding on both of them unless the Secretary determines that it is not appropriate. Regulations section 1.1060-1(c)(4) restates that in regulatory form and then qualifies it twice. First, nothing in the paragraph restricts the Commissioner's authority to challenge the allocations or values arrived at in an allocation agreement. Second, the paragraph does not apply at all if the parties are able to refute the allocation or valuation under the standards set out in the 1967 Third Circuit decision the regulation names, which the regulation summarizes as requiring a party challenging the tax consequences of an agreement, as construed by the Commissioner, to offer proof that would be admissible in an action between the parties to alter that construction or show the agreement unenforceable for reasons such as mistake, undue influence, fraud or duress.

So the agreement binds the parties to each other far more firmly than it binds the government, and the route out of it that the regulation recognizes is an evidentiary standard rather than a change of mind. A buyer who signs a schedule loaded toward Class VII and later takes a different position on its own return is arguing against its own agreement under that standard, while the same schedule gives neither party protection if the values cannot be supported.

A hypothetical that shows the fork rather than predicting a result: a schedule assigns most of the price to a covenant not to compete, and the seller later treats the same amount differently. Before anyone argues about the tax outcome, the questions are whether there is a written agreement within section 1060(a), what exactly it allocates, and whether the values behind it can be supported independently of the parties' tax preferences.

5. Reporting, and what a later price change does

Regulations section 1.1060-1(e)(1)(i) requires the seller and the purchaser in an applicable asset acquisition each to report the amount of consideration and its allocation among the assets transferred, and to report information about subsequent adjustments to consideration. Section 1.1060-1(e)(1)(ii)(A) specifies the mechanism: each files an asset acquisition statement on Form 8594 with its income tax return for the taxable year that includes the first date assets are sold pursuant to the acquisition.

A price that moves later does not simply overwrite the original schedule. Regulations section 1.1060-1(e)(1)(ii)(B) provides that where an increase or decrease in consideration is taken into account after the close of the first taxable year that includes the first date assets are sold, the seller and the purchaser each must file a supplemental asset acquisition statement on Form 8594 with the return for the taxable year in which the increase or decrease is properly taken into account. The Instructions for Form 8594 then set out how an increase is allocated forward and how a decrease is unwound from Class VII backwards, and note that an amount allocated to an asset cannot be decreased below zero.

The instructions list exceptions from filing, including a group of assets exchanged for like-kind property in a transaction to which section 1031 applies and a transfer of a partnership interest, and they state that a party who does not file a correct Form 8594 by the due date of its return and cannot show reasonable cause may be subject to penalties under sections 6721 through 6724. State the rule and the conditions; whether it reaches a particular filer depends on the transaction and the return involved.

6. What does not turn on deal form

Several issues that deal summaries file under form are really about facts. Whether goodwill exists is a character question under Regulations section 1.1060-1(b)(2), not a drafting choice. Whether a covenant not to compete is a separate section 197 intangible depends on what was bargained for. And liabilities do not vanish in either structure: the Instructions for Form 8594 treat the purchaser's consideration as the cost of the assets and the seller's as the amount realized, and value assets gross of the liabilities to which they are subject.

Successor liability, bulk sale rules, and transfer taxes are the substance of most asset-versus-share debates in practice, and they are state law, outside the scope of this federal page. The sibling page titled Section 338(g) or 338(h)(10): an election issue map for a qualified stock purchase handles the case where a share purchase is elected into asset treatment, and does not repeat the allocation mechanics given here.

With the asset schedule drafted, ask Taxterity for the authorities behind each class determination in your own fact pattern, or run a Federal Tax Memo on the allocation, and check every citation against the current Code, regulations and form instructions before filing anything.

• The biggest practical differences between asset and share deals for many buyers are successor liability and transfer taxes, which are state law and are excluded here.
• Whether a group of assets constitutes a trade or business, and what any asset is worth, are fact questions this page frames but does not answer.
• Regulations section 1.1060-1(c)(4) incorporates a judicial standard by naming a 1967 court of appeals decision. This page reports what the regulation says about that standard; the decision itself was not opened and its later treatment was not researched.
