Selling a business is the largest financial transaction most business owners will ever undertake, and the tax treatment of the sale can vary by $50,000-$500,000 depending on how the sale is structured. The two primary structures are: (1) an asset sale, where the buyer purchases the individual assets of the business (equipment, inventory, goodwill, customer lists), and (2) a stock/interest sale, where the buyer purchases the owner’s equity (shares of a corporation or membership interest in an LLC). Each structure has different tax consequences for the buyer and seller.

✓Key takeaway

Asset sale vs stock/interest sale:

Asset sale:

Seller: Each asset is sold separately. Gain on each asset is characterized differently: equipment (Section 1245 recapture, ordinary income), real property (unrecaptured Section 1250 gain taxed at a maximum 25%), goodwill (capital gain), inventory (ordinary income), covenant not to compete (ordinary income). The mix of asset classes determines the effective tax rate.
Buyer: Gets a stepped-up basis in all assets purchased. Can depreciate/amortize the purchase price (equipment over 5-7 years, goodwill over 15 years, buildings over 39 years). This produces tax deductions that reduce the after-tax cost of the acquisition.
Most common for: Sole proprietorships, single-member LLCs, S-Corps (where the buyer wants a basis step-up)

Stock/interest sale:

Seller: Sells equity at capital gains rates (0/15/20%, plus 3.8% NIIT unless an exclusion applies, such as the look-through for an S-Corp owner who is active in the business). No ordinary income recapture on individual assets for corporate stock (an LLC interest taxed as a partnership can still carry ordinary recapture income). One simple calculation: sale price minus basis in the stock/interest = capital gain.
Buyer: Gets NO stepped-up basis in the underlying assets (the buyer takes over the existing depreciation schedules). No new depreciation deductions on the purchase price. This makes the acquisition more expensive on an after-tax basis.
Most common for: C-Corps (where the seller wants to avoid double taxation at the corporate and shareholder level)

IRC 338(h)(10) election: Available for S-Corps. The buyer and seller jointly elect to treat a stock sale as if it were an asset sale for tax purposes. The buyer gets the stepped-up basis, and the seller reports the gain as if each asset were sold individually (mix of ordinary and capital gain). This is a negotiation point: the buyer pays a lower effective price (due to future depreciation), and the seller may accept a slightly higher purchase price to compensate for the ordinary income component.

How does the structure affect total tax?

Hypothetical example

Round numbers. An S-Corp is sold for $1,000,000. The owner’s stock basis is $200,000. The figures assume the owner is not active in the business, so the 3.8% NIIT applies; an active owner may owe little or none of it. The business assets have the following values and bases:

Assets:

Equipment (FMV $200,000, basis $50,000): depreciation recapture
Inventory (FMV $100,000, basis $80,000): ordinary income
Goodwill (FMV $600,000, basis $0): capital gain
Covenant not to compete (FMV $100,000): ordinary income

Stock sale:

Capital gain: $1,000,000 - $200,000 = $800,000
Tax (20% + 3.8% NIIT): $800,000 x 23.8% = $190,400
Net proceeds: $809,600

Asset sale (with IRC 338(h)(10) or actual asset sale):

Equipment gain: $150,000 ordinary (Section 1245) x 37% = $55,500
Inventory gain: $20,000 ordinary x 37% = $7,400
Goodwill: $600,000 capital x 23.8% = $142,800
Covenant: $100,000 ordinary x 37% = $37,000
Total tax: $242,700
Net proceeds: $757,300

Difference: $52,300 more tax on asset sale.

However, the buyer saves approximately $180,000 in future tax deductions (depreciation and amortization of the stepped-up basis). This value is used in negotiation: the buyer may pay a higher purchase price ($1,050,000-$1,100,000) to account for the seller’s higher tax burden on an asset sale, because the buyer’s tax savings from the step-up more than cover the price increase.

Illustrative numbers only, not a real client and not advice for your facts.

Can I spread the gain from a business sale over multiple years?

If the buyer pays in installments, you can report the gain proportionally under IRC 453 as you receive each payment. The installment method applies automatically to any sale where at least one payment is received after the tax year of the sale. Each payment consists of three components: return of basis (tax-free), gain (taxed at capital gains rates), and interest income (taxed as ordinary income). Dealer dispositions, sales of inventory, and sales of depreciable property to a related party don’t qualify for installment treatment. If you elect out of the installment method (by reporting the full gain in the year of sale), you cannot reverse that election without IRS consent.

How are long-term and short-term capital gains taxed differently?

Short-term capital gains (assets held one year or less) are taxed at ordinary income rates, which can be as high as 37%. Long-term capital gains (assets held more than one year) are taxed at preferential rates: 0%, 15%, or 20% depending on your taxable income. The 3.8% net investment income tax (NIIT) applies on top of both rates for taxpayers with modified AGI above $200,000 ($250,000 married filing jointly). The holding period is critical for tax planning: selling an asset one day before the one-year mark costs you the rate differential, which can be 20+ percentage points. Installment sales under IRC 453 can spread the recognition of gain over multiple years.

How do capital gains rates differ in an asset vs stock sale?

If you sell S corporation stock you’ve held more than one year, the gain is generally a single long-term capital gain, taxed for 2025 at 0%, 15% or 20%, with 20% starting above $600,050 of taxable income for joint filers ($613,700 for 2026). An asset sale splits the price across the assets, and depreciation recapture on equipment is ordinary income taxed at up to 37%.

Buildings sold in an asset sale carry unrecaptured section 1250 gain, taxed at a maximum 25%. The 3.8% net investment income tax isn’t automatic in either structure. Gain on property used in a business you actively run is excluded, and when you sell S corporation or partnership interests the gain counts only as far as it would if the entity sold all its assets at fair market value.
