Asset Sale vs Stock Sale
Work this with the Deal Structure Explorer.
Two Ways to Sell the Same Company
The same business can be sold two ways. In an asset sale, the buyer purchases the assets and takes on only the liabilities they agree to, leaving the legal entity with you. In a stock or equity sale, the buyer purchases the entity itself and everything inside it, known and unknown. The choice is not a formality; it changes who carries which risks and who pays which taxes, which is why it surfaces early in every negotiation. Which two you get depends on what you own. A corporation or an LLC can be sold either way, because there are shares or membership units to hand over. A sole proprietorship has neither, so there is nothing to buy but the assets. A partnership is different, because a partner can sell their interest in it, and so is a single-member LLC, whose owner can sell the membership even though its income goes on the owner's own tax return. If the business was never formed as an entity at all, the choice below has already been made for you.
Why Buyers Prefer Assets
Buyers, and the lenders financing them, usually push for an asset sale for two reasons. It draws a line under most old liabilities, so a lawsuit the buyer never saw usually stays with the seller. The exception is the one this site holds as data: unpaid state sales tax can follow the assets to the buyer, in most states up to the purchase price, unless a clearance certificate is obtained. Expect a buyer to hold back part of the price until yours arrives. And it gives the buyer a step-up in basis on what they bought, which they then depreciate, a real cash benefit over the years that follow. For most acquisition-financed deals, an asset structure is the buyer's default expectation.
Why Sellers Often Prefer Stock
Sellers frequently lean the other way. A stock sale can be simpler, can leave contracts and licenses attached to the entity so they need no reassignment, and can produce a cleaner single layer of tax rather than a mix. But because buyers resist it, a stock sale is usually a point of leverage to trade, not a default you can assume. What you give up elsewhere to get it should be priced deliberately.
Where the Tax Lives
Inside an asset sale, the purchase price is allocated across categories of assets, and that allocation drives how much of your proceeds are taxed as favorable capital gains versus ordinary income, and how much the buyer can depreciate. Buyer and seller have opposite incentives on that split, so it is negotiated and then reported consistently by both sides. It can move your after-tax result as much as a meaningful change in the headline price, which is why the tax page on this wing treats it as its own decision.
License and Contract Transfer
Assignability often decides the structure in practice. Where key contracts, leases, or a hard-to-transfer license sit inside the entity and cannot easily be reassigned, that can push a deal toward a stock sale or a carefully engineered workaround, whatever the tax preference. In regulated and licensed trades especially, mapping what transfers with the assets and what stays stuck to the entity belongs in your diligence file before the structure is set.
What the Data Says
An asset sale is not finished when the money moves. Both the buyer and the seller generally must file Form 8594 with their returns when a group of assets making up a trade or business changes hands and goodwill could attach to it. The price is then spread across seven asset classes by the residual method, with goodwill and going concern value taking whatever is left in the last class. Both returns report that allocation, which is why it belongs in the purchase agreement and not in an accountant's inbox in April.
