How Is a Business Acquisition Taxed?
Tax enters a business acquisition at four points: the structure of the deal decides who is treated as selling what; the allocation of the purchase price decides how each dollar is characterized; the buyer’s side of that allocation decides what the buyer deducts in the years after closing; and the seller’s side decides how much of the gain is ordinary income, how much is capital gain, and when it is recognized. None of these is a filing-season question. All four are set by decisions made between the LOI and the purchase agreement, which is why the tax analysis belongs before the price is agreed, not after.
This article maps the four points, cites the rule that governs each, and shows how they connect on a typical lower-middle-market deal.
Where does tax enter a business acquisition?
At four decision points, each governed by its own part of the Code. The table maps them; the sections below take each in turn.
| Decision point | What it determines | Governing authority |
|---|---|---|
| Structure: asset, stock, or stock with an election | Whose basis survives; what the seller is treated as selling; which liabilities and attributes move | IRC 1012, 338, 336(e); Rev. Rul. 99-6 for LLC interests |
| Purchase price allocation | How each dollar of price is characterized for both sides | IRC 1060; Treas. Reg. 1.338-6; Form 8594 |
| Buyer's cost recovery | What the buyer deducts after closing, and over what period | IRC 168 (tangible property), IRC 197 (intangibles), Treas. Reg. 1.263(a)-5 (transaction costs) |
| Seller's gain: character and timing | Ordinary versus capital, one tax layer versus two, this year versus over the note | IRC 1245, 336(a), 331(a), 453 |
This is general information about federal tax rules, not advice for your specific transaction. Structure, allocation, and elections should be confirmed with your own tax advisor and counsel.
How does the structure determine who is taxed on what?
The structure is the master switch, and it is covered in full in asset sale vs. stock sale: which is better for buyers. The short version for this framework: in an asset purchase the buyer takes a cost basis in each asset under IRC section 1012 and the seller recognizes gain asset by asset. In a stock purchase without an election, the corporation’s basis in its assets continues unchanged, the buyer’s cost basis attaches to the stock instead, and the seller’s gain is measured on the stock. A section 338(h)(10) or 336(e) election keeps the legal form of a stock deal while taxing it as an asset sale. And for the many small businesses held as LLCs taxed as partnerships, buying all the interests is treated for the buyer as buying the assets, with a cost basis under section 1012. (Source: IRC section 1012(a); IRC section 338(h)(10); IRC section 336(e); Rev. Rul. 99-6, Situation 2.)
Everything that follows in this article applies in an actual asset purchase, and equally in a deemed one produced by an election.
How is the purchase price allocated, and why does it bind both sides?
When the assets transferred constitute a trade or business, IRC section 1060 requires the consideration to be allocated among the acquired assets under the residual method: through the asset classes of the regulations in order, with each asset capped at fair market value, and the residual landing in goodwill and going concern value. Both buyer and seller report the allocation to the IRS on Form 8594, and a written allocation the parties agree on is binding on both unless the IRS determines it is inappropriate. (Source: IRC section 1060(a) through (c); Treas. Reg. section 1.338-6(b).)
Two practical consequences follow. First, the allocation is adverse in interest: dollars allocated to equipment give the buyer faster deductions but give the seller ordinary recapture income, while dollars allocated to goodwill amortize slowly for the buyer and are generally capital gain for the seller. That tension makes the allocation a negotiated term, not an accounting formality, and it belongs in the purchase agreement. Second, because both sides file Form 8594, allocations that do not match invite scrutiny. Framed as practitioner judgment: agree the allocation in the deal documents, not after closing. The allocation classes and Form 8594 mechanics are worked in detail in purchase price allocation in a business sale.
What does the buyer deduct after closing?
Three streams, on three different clocks.
Depreciation on tangible property. Basis allocated to equipment, vehicles, furniture, and similar property is depreciated under IRC section 168 from the buyer’s cost, on recovery periods set by property class. Depending on the class of property and the rules in force at closing, expensing under section 179 or the special allowance under section 168(k) may accelerate some of it. (Source: IRC section 168; sections 179 and 168(k) referenced without stating current limits.)
Amortization of intangibles. Basis allocated to goodwill, going concern value, customer relationships, workforce, licenses, trade names, and a covenant not to compete entered in connection with the acquisition is amortized ratably over 15 years beginning with the month of acquisition, under IRC section 197. One consequence surprises buyers: a covenant not to compete acquired with a business is a section 197 intangible, so it amortizes over 15 years even if the covenant itself runs only three. (Source: IRC section 197(a), (c), (d)(1).)
Transaction costs, mostly capitalized. Amounts paid to facilitate the acquisition of a trade or business (investment banking and advisory fees, legal fees for the transaction documents, diligence performed in pursuing the deal) must generally be capitalized rather than deducted. For a taxable asset or stock acquisition, the regulation draws a bright line: amounts relating to activities on or after the earlier of the letter of intent or board approval of the transaction facilitate the deal, and certain inherently facilitative costs (appraisals, structuring the transaction, preparing the documents) are capitalized whenever incurred. (Source: Treas. Reg. section 1.263(a)-5(a), (b), (e).) Framed as practitioner judgment: keep advisor invoices itemized between investigation-stage and transaction-stage work, because the paperwork you keep during the deal determines what your CPA can support after it.
How is the seller taxed on the sale?
Not at one rate on one number. Four rules divide the seller’s proceeds.
Character: recapture first. In an asset sale, gain on depreciable personal property is ordinary income to the extent of depreciation previously taken, under IRC section 1245; prior amortization on section 197 intangibles is recaptured the same way. The remaining gain on the business’s capital and section 1231 assets, and gain on a stock sale, is generally capital. (Source: IRC section 1245(a); IRC section 197(f)(7).)
Entity: one layer or two. An S corporation or partnership seller generally has one level of tax, with gain passing through to the owners. A C corporation that sells assets recognizes corporate-level gain, and its shareholders recognize gain again when the proceeds come out in liquidation. (Source: IRC section 336(a); IRC section 331(a).) This is the single largest seller-side driver of deal structure, and it is why the structure article treats the C corporation case separately.
Timing: the installment method. When part of the price is a seller note, so that at least one payment arrives after the year of sale, the sale is an installment sale and the seller reports gain under the installment method: each year’s payments carry gain in proportion to the gross profit ratio on the contract. The important exception cuts the other way: recapture income under section 1245 is recognized in full in the year of disposition, even if the cash arrives later. A seller carrying a large note against a heavily depreciated asset base can owe ordinary-income tax in year one on money not yet received. (Source: IRC section 453(a), (b), (c), (i).) How a seller note interacts with SBA coverage on the buyer’s side is a separate question, covered in how does a seller note affect DSCR.
Payments for services or covenants. Amounts the seller receives under a genuine consulting agreement are ordinary compensation income to the seller when earned, and payments allocated to a covenant not to compete are ordinary income to the seller as received, even though the buyer amortizes the covenant over 15 years. Framed as practitioner judgment: sellers should price these components with their character in mind, because a dollar moved from goodwill to a covenant or consulting fee is usually a dollar moved from capital gain to ordinary income.
Illustrative example: one deal, both sides
All figures are illustrative and round. They are not typical results, no tax rates are stated, and every deal’s numbers differ. A buyer pays $1,500,000 for the assets of an S corporation: $100,000 inventory, $400,000 equipment (fully depreciated by the seller), $50,000 covenant not to compete, and $950,000 goodwill (self-created, so the seller has no basis in it).
| Deal element | Buyer's treatment | Seller's treatment |
|---|---|---|
| Inventory, $100,000 | Recovered through cost of goods sold as sold | Ordinary income to the extent of any margin over its basis |
| Equipment, $400,000 | Depreciated from $400,000 under IRC 168 | $400,000 ordinary income: gain to the extent of prior depreciation (IRC 1245) |
| Covenant, $50,000 | Amortized over 15 years (IRC 197), about $3,333 per year | Ordinary income as received |
| Goodwill, $950,000 | Amortized over 15 years (IRC 197), about $63,333 per year | Generally capital gain (no prior amortization to recapture) |
| Deal costs, say $60,000 | Capitalized under Reg. 1.263(a)-5, not deducted currently | Seller's own transaction costs generally reduce the amount realized |
If $500,000 of the price is a seller note, the capital gain spreads over the note’s payments under the installment method, but the $400,000 of equipment recapture is recognized in the year of sale regardless. That single interaction, recapture now and cash later, is the most common unpleasant surprise in seller-financed asset deals, and it is discoverable months before the LOI.
When should the tax analysis happen, and who does what?
Framed as practitioner judgment: the tax analysis belongs in the pre-LOI window, alongside the coverage math in the pre-LOI acquisition checklist. The structure and the allocation drive both sides’ after-tax results, and both harden quickly: the LOI often names the structure, the purchase agreement fixes the allocation, and the bright-line date in the transaction-cost regulation makes even the LOI’s signing date a tax event of sorts. Modeling structure, allocation, recapture, and installment timing before terms lock costs a few hours; reopening any of them after signing costs negotiating leverage, and sometimes the deal.
The division of labor matters too. The modeling described here is financial and tax analysis. The purchase agreement, the entity filings, and any formal tax opinion remain with your attorney, and this article is not a substitute for either advisor on a specific transaction.
