Asset Sale vs. Stock Sale: Why How You Sell Changes the Tax Bill

Two business owners sell identical companies for the same price — and one keeps far more after tax than the other. The difference isn't the number on the contract. It's how the sale was structured: as an asset sale or a stock sale, and how the price was allocated. This is where business-tax knowledge is worth real money.

Asset sale vs. stock sale — who prefers which

In a stock sale, the buyer purchases your ownership interest; your gain is generally a single capital gain — clean and seller-friendly. In an asset sale, the company sells its individual assets; the buyer usually prefers this (they get a stepped-up basis to depreciate), but it can convert a chunk of your proceeds into higher-taxed ordinary income.

The hidden driver: purchase-price allocation (§1060)

In an asset sale, the price is allocated across asset classes — cash, receivables, inventory, equipment, §197 intangibles, and goodwill. Each class has its own tax character:

• Goodwill → capital gain (the seller's friend)
• Equipment with prior depreciation → ordinary income via recapture
• Inventory → ordinary income

How the contract allocates the price literally determines your tax rate. Buyer and seller have opposite incentives here — and both must report the same allocation on Form 8594.

Why an installment structure changes the math

Whichever form the sale takes, taking the proceeds over time rather than in one lump sum can spread the capital-gain portion across years — lowering the bracket, softening the 3.8% NIIT, and avoiding the income cliffs a lump-sum sale triggers.

The bottom line

Selling a business is not one decision — it's a series of tax choices (entity, sale form, allocation, timing) that together can swing your after-tax result by a fortune. Have those conversations before the letter of intent, not after.
