Cash consideration is the money a buyer pays a seller in exchange for a business, its assets, or its stock. It is the most straightforward form of payment in a merger or acquisition because the value is fixed at the moment of transfer, with no fluctuating share price or promissory note between the parties. The headline purchase price, though, rarely equals the cash that reaches the seller’s account. Working capital adjustments, escrow holdbacks, earn-outs, and tax obligations all reshape the final payout, sometimes by a wide margin.
What Cash Consideration Actually Is
Cash consideration satisfies the requirement that each side to a contract give up something of value. In a business sale it means liquid currency flowing to the seller in return for stock or assets. Because the amount is known at closing, cash carries none of the price-movement risk of stock consideration and none of the collection risk of a seller-financed note. That certainty is why sellers generally prefer cash and why a clean cash offer tends to move faster from letter of intent to signed agreement.
Where the cash lands depends on deal structure. In a stock acquisition, the buyer pays the selling shareholders directly. In an asset purchase, the cash goes to the target company itself, which then distributes proceeds to its owners. That routing looks like a technicality, but it drives most of the tax differences discussed below.
Why the Headline Price Isn’t What the Seller Receives
The purchase price printed in the agreement is a starting number. Several mechanisms adjust the actual cash changing hands, because a business isn’t static between signing and closing, and because the buyer needs recourse if the seller’s representations turn out to be wrong.
Working Capital Adjustments
Most agreements set a “working capital peg,” an agreed level of current assets minus current liabilities the business should carry at closing. If actual working capital falls below the peg, the purchase price drops dollar-for-dollar. If it exceeds the peg, the seller gets more. A post-closing true-up, typically completed within 60 to 90 days after closing, finalizes the calculation once both sides review the numbers.
Escrow and Holdbacks
Buyers commonly hold back 5% to 15% of the deal value in an escrow account managed by a third-party agent. The escrow secures the buyer against breaches of the seller’s representations and warranties: an overstated revenue figure, an undisclosed lawsuit, an environmental problem. Escrow periods typically run 12 to 24 months, and whatever remains unclaimed is released to the seller at the end.1Bloomberg Law. M&A Overview – Escrow Accounts in M&A
Holdbacks work similarly but sit with the buyer instead of a neutral third party. They tend to be tied to specific anticipated liabilities such as a known environmental cleanup or a pending tax audit. Both mechanisms reduce the seller’s immediate cash and give the buyer a pool to draw from if problems surface.
Earn-Outs and Deferred Payments
When the parties disagree on what the business is worth, an earn-out can bridge the gap. Part of the purchase price becomes contingent on the acquired business hitting specified financial targets (revenue, EBITDA, or another agreed metric) over a defined post-closing period. Hit the targets and the seller earns the additional payment; miss them and the buyer keeps the difference.
Earn-outs are among the most litigated provisions in deal-making. The seller no longer runs the business, yet the payout depends on how it performs. Disputes over accounting methods, capital investments that suppress short-term earnings, and operational changes are common. Metrics, measurement periods, and accounting standards need to be pinned down precisely in the purchase agreement.
Deferred payments differ from earn-outs. They are simple installments paid on a fixed schedule regardless of performance. They manage the buyer’s immediate cash outlay without linking payments to future results, and the tax reporting rules diverge from earn-out rules.
Resolving Post-Closing Disputes
Purchase agreements typically build in a dispute-resolution process for working capital adjustments, earn-out calculations, and other true-ups. Each side gets a window to review and object. If they cannot agree, the dispute goes to an independent accounting firm acting as a neutral referee, whose determination on the specific items in dispute is binding.
Tax Consequences for the Seller
Receiving cash is almost always a fully taxable event. Unlike a stock-for-stock reorganization, where tax can sometimes be deferred, a cash sale forces the seller to recognize gain or loss in the year of closing. The size of the bill depends on structure, what’s being sold, and how long the assets were held.
Stock Sales
When shareholders sell stock for cash, gain equals total cash received minus the shareholder’s adjusted tax basis. Stock held more than one year qualifies for long-term capital gains rates, which top out at 20% for the highest earners. Stock held a year or less is taxed at ordinary income rates up to 37%.2Internal Revenue Service. Topic no. 409 – Capital Gains and Losses A stock sale is simpler for the seller because there is one asset and one tax character, which is a big reason sellers push for stock deals.
Asset Sales and Allocation
An asset sale forces the seller to allocate the total cash across every individual asset transferred: equipment, inventory, real estate, customer lists, goodwill, and the rest. Both sides must agree on the allocation and report it consistently to the IRS using Form 8594.3Internal Revenue Service. Instructions for Form 8594 Federal law requires a residual method that distributes the price across seven asset classes, from cash and securities at the top down to goodwill and going concern value at the bottom.4Office of the Law Revision Counsel. 26 USC 1060 – Special Allocation Rules for Certain Asset Acquisitions
Each class carries its own tax treatment. Inventory is taxed as ordinary income. Depreciated equipment triggers Section 1245 recapture, so the portion of gain attributable to prior depreciation deductions is taxed at ordinary income rates rather than capital gains rates.5Office of the Law Revision Counsel. 26 US Code 1245 – Gain From Dispositions of Certain Depreciable Property Depreciated real property triggers a similar recapture under Section 1250, with unrecaptured gain taxed at a maximum 25% rate.2Internal Revenue Service. Topic no. 409 – Capital Gains and Losses Only the portion allocated to goodwill and long-held capital assets gets the favorable long-term rate.
The allocation negotiation gets intense for a reason. The seller wants more of the price sitting in goodwill and capital assets for lower rates. The buyer wants more in short-lived depreciable assets for faster write-offs. The final price often implicitly reflects the pull of those competing preferences.
The 3.8% Net Investment Income Tax
Sellers with modified adjusted gross income above $200,000 (single) or $250,000 (married filing jointly) face an additional 3.8% net investment income tax on capital gains from the sale. The surtax applies to the lesser of net investment income or the amount by which income exceeds the threshold.6Internal Revenue Service. Net Investment Income Tax On a multimillion-dollar sale, it effectively lifts the top capital gains rate from 20% to 23.8%, and it is easy to miss in early deal modeling.
Installment Reporting for Payments Received Later
When part of the cash arrives after the year of sale, whether through an earn-out, seller financing, or scheduled installments, the seller can generally report gain as payments come in rather than all at once. The installment method under Section 453 applies automatically to qualifying sales unless the seller elects out of it.7Office of the Law Revision Counsel. 26 US Code 453 – Installment Method It does not apply to inventory sales or dealer dispositions. Each payment breaks into return of basis (tax-free), capital gain, and interest, and the gain proportion stays constant across the payout period.
One trap: if a deferred payment arrangement lacks adequate stated interest, the IRS imputes interest at the applicable federal rate and recharacterizes part of each payment as ordinary interest income rather than capital gain.8Office of the Law Revision Counsel. 26 US Code 1274 – Determination of Issue Price in the Case of Certain Debt Instruments Issued for Property Deal counsel should confirm that all deferred payment terms carry interest at or above the applicable federal rate.
When Escrowed Cash Is Taxed
Cash sitting in escrow generally is not taxed until it is released to the seller, provided the seller cannot direct or access the funds during the escrow period. That defers the tax on the escrowed portion, which matters when 10% or more of the price sits in escrow for a year or two. Earn-out payments are taxed in the year received, spreading the liability across multiple tax years.
Qualified Small Business Stock
Sellers of qualifying C corporation stock may exclude a substantial portion of their gain from federal tax under Section 1202. The corporation must be a domestic C corporation with gross assets that never exceeded $75 million, and the stock must have been acquired at original issue in exchange for money, property, or services.9Office of the Law Revision Counsel. 26 US Code 1202 – Partial Exclusion for Gain From Certain Small Business Stock
The exclusion depends on holding period. For stock acquired after the applicable date under current law, holders who have owned the stock at least five years can exclude 100% of the gain, up to the greater of $15 million or ten times the stock’s adjusted basis. Shorter holding periods yield partial exclusions: 75% at four years and 50% at three years.9Office of the Law Revision Counsel. 26 US Code 1202 – Partial Exclusion for Gain From Certain Small Business Stock The corporation must meet an active business requirement throughout the holding period, and several industries are excluded, including financial services, hospitality, farming, and mining. For founders and early investors, Section 1202 can wipe out the federal tax on a cash sale entirely.
Tax Consequences for the Buyer
The buyer’s tax position mirrors the seller’s, which is why the two sides usually push in opposite directions on structure.
Stock Purchase: Carryover Basis
When a buyer purchases stock, the buyer’s basis in the shares equals the cash paid, but the tax basis of the company’s underlying assets stays exactly where it was. If the target bought equipment five years ago and has been depreciating it since, the buyer inherits the remaining schedule. No fresh start. This carryover basis is the main reason buyers resist stock deals: premium price, used-up deductions.
Asset Purchase: Step-Up in Basis
In an asset purchase, the buyer allocates total cash paid (plus liabilities assumed) across the acquired assets using the same residual method and Form 8594 classes the seller uses.10Internal Revenue Service. About Form 8594, Asset Acquisition Statement Under Section 1060 The result is a new, stepped-up basis in every asset, often much higher than the target’s old book value. The buyer depreciates tangible assets from the new basis and amortizes intangible assets, including goodwill and customer lists, over 15 years under Section 197.11Office of the Law Revision Counsel. 26 US Code 197 – Amortization of Goodwill and Certain Other Intangibles
Those amortization deductions are a real tax shield. A buyer that pays $10 million and allocates $4 million to goodwill can deduct roughly $267,000 per year for 15 years against future income. The present value of that shield often shows up in what a buyer is willing to pay for an asset structure.
The Section 338(h)(10) Hybrid
In limited cases the parties can have it both ways. A Section 338(h)(10) election treats a qualified stock purchase as an asset purchase for federal tax purposes while it remains a stock purchase for every other legal purpose, so contracts, licenses, and permits transfer with the stock but the buyer gets a stepped-up basis in the assets. Both sides must agree, and the election works only for acquisitions of S corporations or members of a consolidated group. When it fits, it is often the most tax-efficient path for both sides.
Section 1031 and Its Narrow Scope
Sellers sometimes ask about rolling cash proceeds into a like-kind exchange under Section 1031. Since the Tax Cuts and Jobs Act took effect in 2018, Section 1031 applies only to real property. Machinery, equipment, vehicles, intellectual property, and other business personal property no longer qualify.12Internal Revenue Service. Like-Kind Exchanges – Real Estate Tax Tips If the sale includes commercial real estate, that portion may still qualify, but a qualified intermediary has to hold the proceeds. Taking direct control of the cash disqualifies the exchange.
Cash Compared to Stock and Seller Notes
Cash gives the seller a known, final value at closing. The tradeoff is immediate taxation. Stock consideration ties the payout to the buyer’s share price, and a 30% drop in that stock after closing is effectively a 30% price cut for the seller. Lock-ups that restrict resale for months or years amplify that risk.
Stock has one meaningful advantage. In a qualifying corporate reorganization under Section 368, the seller can defer capital gains tax until the received stock is eventually sold.13Office of the Law Revision Counsel. 26 US Code 368 – Definitions Relating to Corporate Reorganizations A seller planning to hold the buyer’s stock long-term may value that deferral more than the certainty of cash, but the transaction must satisfy strict requirements, generally an acquisition made solely or primarily for voting stock, and many deals do not qualify.
A seller-financed promissory note introduces credit risk. The seller is lending money to the buyer, backed by a promise to pay principal and interest over time. If the buyer’s business deteriorates, the seller may not collect the full amount. Cash carries no counterparty risk once it clears. Many large transactions blend the three: a fixed cash component for certainty, a stock component for alignment, and sometimes a note to bridge remaining gaps.
HSR Filing Thresholds for Large Cash Deals
Cash transactions above a certain size trigger federal antitrust review. Under the Hart-Scott-Rodino Act, buyer and seller both file a premerger notification with the Federal Trade Commission and the Department of Justice and observe a waiting period, typically 30 days, before closing. For 2026, the minimum transaction value that triggers the filing requirement is $133.9 million.14Federal Trade Commission. New HSR Thresholds and Filing Fees for 2026
Filing fees scale with deal size and are paid by the acquiring party:
- Under $189.6 million: $35,000
- $189.6 million to $586.9 million: $110,000
- $586.9 million to $1.174 billion: $275,000
- $1.174 billion to $2.347 billion: $440,000
- $2.347 billion to $5.869 billion: $875,000
- $5.869 billion and above: $2,460,000
Thresholds adjust annually with changes in gross national product.14Federal Trade Commission. New HSR Thresholds and Filing Fees for 2026 Failing to file when required can bring penalties of over $50,000 per day, so deal teams in the middle market and above should confirm HSR applicability early rather than at signing.
