Asset sale vs stock sale at a glance
| At a glance | Asset sale | Stock sale |
|---|---|---|
| What is sold | The company sells its individual assets. The seller usually keeps the legal entity. | The owners sell their shares or interests. The buyer takes the entity, history and liabilities included [2]. |
| How the gain is taxed | Each asset is treated as sold separately, so one sale can produce ordinary income, depreciation recapture and capital gain at the same time [2]. | Usually treated as the sale of a single capital asset, so gain is usually capital gain [2]. |
| Who usually prefers it | Buyers. They get a new tax basis and can depreciate or amortize it again, including goodwill [7]. | Sellers, especially C corporation owners: usually one level of tax and capital gain treatment. |
| C corporation | Two layers: the corporation is taxed on its gain, then shareholders are taxed again when the proceeds are distributed in liquidation [15] [16]. | One layer, at the shareholder level. |
| S corporation, partnership or LLC | Gain generally passes through to the owners' personal returns, keeping its character asset by asset [13]. | Selling an S corporation's stock is usually capital gain. Selling a partnership interest is capital gain except the part tied to receivables and inventory, which is ordinary [18]. |
| Paperwork | Buyer and seller each file Form 8594 with the price allocated across seven asset classes [3]. Business property sales go on Form 4797 [4]. | Reported as a sale of stock or of a partnership interest. Publication 550 covers sales of stock [20]. |
Form 8594 asset classes and the typical character of gain
| Class | What it includes | Typical character of the seller's gain |
|---|---|---|
| Class I | Cash and general deposit accounts. | Usually no gain. Cash is cash. |
| Class II | Actively traded personal property, certificates of deposit, foreign currency. | Usually little gain. |
| Class III | Accounts receivable and other assets marked to market, plus certain debt instruments. | Receivables not yet taxed (common for cash-basis businesses) usually produce ordinary income. |
| Class IV | Inventory and property held mainly for sale to customers. | Ordinary income. Inventory is not a capital asset [2]. |
| Class V | Everything not in another class: equipment, vehicles, furniture, buildings, land. | Gain up to prior depreciation on equipment is recaptured as ordinary income [5]. Buildings follow section 1250 [6]. Remaining gain is usually section 1231 gain [2]. |
| Class VI | Section 197 intangibles other than goodwill: customer lists, licenses, trademarks, workforce, non-compete covenants. | Mixed. Self-created intangibles usually follow section 1231; ask how a non-compete payment is taxed to you. |
| Class VII | Goodwill and going concern value: whatever price is left after Classes I to VI. | For an owner who built the business, usually section 1231 gain, which can be taxed like long-term capital gain [2]. |
What actually determines your tax bill
There is no single tax rate on selling a business. The sale is not one transaction for tax purposes but a bundle of them, and each piece can be taxed differently. Two owners selling for the same price can owe very different amounts. These are the levers:
- Deal structure: whether the buyer purchases the company's assets or your shares. Usually the biggest factor.
- Purchase price allocation: in an asset sale, how the price is split among inventory, equipment, real estate, intangibles and goodwill.
- Your tax basis: what you invested in each asset, less depreciation already deducted.
- Holding period: how long you have owned the asset or the shares.
- Entity type: C corporation, S corporation, partnership or LLC, or sole proprietorship.
- Timing of payment: cash at close, a seller note, an earn-out or an installment schedule.
- Your other income that year, which affects the rates that apply.
- Your state, since state rules on capital gains differ widely.
Gain is what you receive minus your basis, asset by asset
For each asset, gain is the amount you realize minus your adjusted basis. The IRS describes the seller's consideration as the amount realized: money plus the fair market value of property received [2]. Ask your CPA how debts the buyer takes over, seller financing and contingent payments are counted in your case, because those details move both the total and the timing.
Basis is usually what you paid for an asset plus improvements, minus depreciation and amortization you have deducted over the years. Years of depreciation lowered your taxes while you ran the business; the sale is where some of that benefit is paid back. Self-created assets like goodwill often have a basis of zero, so nearly everything allocated to them is gain.
Holding period matters too. The IRS treats gain on property held more than one year as long-term and gain on property held one year or less as short-term [1].
Asset sale vs stock sale: why buyers and sellers disagree
In a stock sale, the IRS says the sale of corporate stock or a controlling interest in a corporation is treated as the sale of a single asset, and selling stock usually produces capital gain or loss [2]. That is why sellers, especially owners of C corporations, often prefer stock deals.
In an asset sale, the IRS says a sale of a business is usually not a sale of one asset; each asset is treated as being sold separately to determine the treatment of gain or loss [2]. Buyers prefer this because they get a fresh basis to deduct again. Goodwill and most other acquired intangibles are amortized over a 15-year period under section 197 [7], and equipment can be depreciated again. They can also leave unknown liabilities behind with the old entity.
Many small business sales are structured as asset sales, so this is often a negotiation over price and terms, not over structure. If an asset deal is expensive for you, the honest conversation is about price: what is your after-tax result under each structure, and will the buyer pay part of the difference? In some cases buyer and seller can make an election under section 338 so that a stock purchase is treated as an asset acquisition for tax purposes [17]. Ask your tax advisor early whether that is available.
How your entity type changes the answer
C corporation. If a C corporation sells its assets and then distributes the proceeds, the corporation generally recognizes gain on the sale, and on liquidating distributions as if it sold the property at fair market value [15]. Shareholders then treat amounts received in a complete liquidation as payment in exchange for their stock [16]. That is the double tax, and it is the reason C corporation owners resist asset sales.
S corporation. S corporations pass corporate income, losses, deductions and credits through to their shareholders, who report them on their personal returns [13]. In an asset sale, gain flows through with its character intact. One trap: an S corporation that used to be a C corporation can owe a corporate-level tax on built-in gains under section 1374 [14]. If your company ever converted, tell your CPA on day one.
Partnership or multi-member LLC. A partnership interest is treated as a capital asset when sold, but the part of the gain tied to unrealized receivables or inventory items is treated as ordinary [2] [18].
Sole proprietorship or single-member LLC taxed as one. There are no shares to sell, so the sale is an asset sale by definition. Allocation is the whole game.
Purchase price allocation: the part most owners overlook
In an asset sale, buyer and seller must both use the residual method to allocate the price to each business asset [2], and both must file Form 8594 with their returns when they transfer a group of assets that makes up a trade or business [3]. The price is allocated through seven classes in order. Each class is filled up to fair market value in order, and whatever is left lands in Class VII, goodwill.
The buyer and seller may agree in writing on the allocation or on the fair market value of assets, and that agreement is binding on both parties unless the IRS determines the amounts are not appropriate [2]. That makes the allocation schedule a real negotiating point, not a formality your accountant fills in after closing.
The incentives usually point in opposite directions. A buyer wants more of the price on assets it can deduct quickly, like equipment and inventory. A seller usually wants more on goodwill, where gain is often taxed more favorably, and less on equipment, where gain up to prior depreciation is recaptured as ordinary income. Values must be defensible, so neither side can assign whatever it likes.
Practical advice: agree the allocation schedule before the purchase agreement is final, and have your CPA compare the after-tax result of the buyer's schedule with a counterproposal. A higher offer can be worse after tax if the allocation is unfavorable.
Depreciation recapture: why equipment-heavy businesses owe more than they expect
When you sell depreciable personal property such as machinery, vehicles or computers, section 1245 treats gain up to the depreciation you previously deducted as ordinary income [5]. Only gain above the original cost, which is rare for used equipment, gets better treatment. Businesses with fleets or heavy machinery feel this most in an asset sale.
Buildings follow a different rule. Section 1250 governs gain on depreciable real property [6], and IRS Topic 409 notes that unrecaptured section 1250 gain from selling section 1250 real property is taxed at a maximum 25% rate [1]. If the business owns its building, decide early whether the real estate is part of the sale, sold separately, or kept and leased to the buyer. Each path is taxed differently.
Gain on business property that is not recaptured is generally section 1231 gain. Its treatment as ordinary or capital depends on whether you have a net gain or a net loss from all section 1231 transactions for the year, and the IRS instructs taxpayers to first determine whether any of the gain is ordinary income under the recapture rules [2]. These sales are reported on Form 4797, Sales of Business Property [4].
What the IRS says about rates, and why we don't estimate yours
IRS Topic 409, last reviewed September 24, 2026, says that for taxable years beginning in 2025 the tax rate on most net capital gain is no higher than 15% for most individuals, that a 0% rate applies below certain taxable income levels, and that a 20% rate applies above the 15% thresholds [1]. The thresholds change every year, so check the current page and the year you will actually close.
The net investment income tax can also apply. The IRS page, last reviewed July 1, 2026, gives the rate as 3.8 percent on net investment income for individuals whose modified adjusted gross income is above statutory threshold amounts [11]. For a sale of an interest in a partnership or S corporation, section 1411 counts gain only to the extent it would have been taken into account if the entity had sold all its property at fair market value [12], which can leave out gain tied to an active business. Whether that helps you depends on your involvement, so ask your CPA.
Ordinary income from inventory, receivables and recapture is taxed at your ordinary income tax rates, which depend on your total taxable income for the year. Payments for consulting or employment after closing are compensation, taxed as wages or self-employment income rather than sale proceeds.
We stop there on purpose. A useful estimate needs your entity, basis by asset, allocation, other income, state and closing year. Any blended rate on a website would be a guess.
Seller notes, earn-outs and installment sales change the timing
If you receive at least one payment after the tax year of the sale, you have an installment sale [8]. The installment method lets you generally recognize gain as payments come in rather than all at once, which can spread income across years. See earn-outs and seller notes for how those terms work commercially.
Depreciation recapture is recognized in the year of the sale even if no payment is received that year [9], and Publication 537 says you must report any depreciation recapture income in the year of sale, whether or not an installment payment was received [8]. That can create a tax bill before the cash arrives. Publication 537 also notes that the price is still allocated among asset classes, and that interest on deferred tax can apply to large installment obligations [8].
Deal terms carry their own tax questions. Ask your advisors about these before you agree to them:
- Earn-outs: when is the contingent amount taxed, and what if it pays less than expected?
- Seller notes: how is the interest taxed separately from the gain?
- Escrows and holdbacks: taxed when funded or when released?
- Consulting agreements: compensation for services, not purchase price, so taxed differently.
- Non-compete payments: how are they taxed to you compared with goodwill?
- Rollover equity: can the stake you keep be structured to defer tax on that portion?
Qualified small business stock (section 1202)
Section 1202 allows a partial or full exclusion of gain on qualified small business stock: stock in a C corporation, acquired at original issue, held for the required period, in a company that met the gross assets and active business requirements [10]. The statute excludes businesses involving the performance of services in fields including health, law, engineering, architecture, accounting, consulting, financial services and brokerage, or where the principal asset is the reputation or skill of employees [10].
Section 1202 was amended by Pub. L. 119-21 on July 4, 2025, which changed some of the rules for stock issued after that date [10]. If your company is a C corporation and you received stock at formation or in an early funding round, ask a tax attorney whether any of your gain qualifies. The benefit applies only in a stock sale.
Related-party sales and state taxes
Selling to a family member or to an entity you control has its own rules. Under section 1239, gain on the sale of depreciable property between related persons can be treated as ordinary income [19].
State taxes vary widely. Some states tax capital gains as ordinary income, some have no personal income tax, some impose taxes on the entity itself, and the state where the business operates may tax the gain even if you live elsewhere. If you plan to move, talk to an advisor before closing. We don't list state rates because they change and depend on your facts.
Questions to bring to your CPA or tax attorney
Hire your tax advisor before you sign a letter of intent, while structure and allocation are still open. Bring these questions to the first meeting:
- What is my after-tax result in an asset sale versus a stock sale at the same price?
- What is my basis in each major asset, and how much depreciation will be recaptured?
- What allocation should I propose, and what does the buyer's allocation cost me?
- Does the net investment income tax apply, given how involved I am?
- Would an installment structure help, and what will I owe in the closing year regardless?
- Was my company ever a C corporation, and does a built-in gains tax apply?
- Could any of my stock qualify under section 1202?
- Which states can tax this gain?
- What estimated tax payments will I owe after closing?
Where taxes show up in due diligence
Buyers review your tax returns, payroll and sales tax filings and any open audits, more closely in a stock sale because they inherit the entity's history. Clean returns and depreciation schedules make allocation and diligence faster. See business sale due diligence for what buyers typically request, and how to sell a business for the full process.
Where Axia fits, and where it doesn't
Axia Growth introduces buyers to owners whose businesses fit the buyer's acquisition criteria. It is engaged and paid by the buyer, and owners pay Axia nothing [21]. See who pays for how that works.
Axia does not represent sellers, value businesses, negotiate terms, structure deals, or take part in due diligence or closing, and it holds no business-broker, real estate or securities license [21]. Axia does not give tax advice. If a buyer conversation turns serious, bring in your own CPA, tax attorney and deal attorney. See also should I use a business broker.
Start with a realistic value, then model the tax
Tax is a share of the gain, and the gain starts with the price. The multiples index shows median EBITDA and SDE multiples by sector and size band [22], and the business value calculator applies them to your earnings in about a minute. See also SDE vs EBITDA and asking price vs sale price.
A value range is not an appraisal, an offer or a tax estimate, but it gives your CPA a starting price to model. You can also read more on the owner valuation page.
