What's the difference between a taxable acquisition and a tax-free reorganization?

In a taxable acquisition, the seller recognizes gain immediately and pays tax now; the buyer usually gets a cost basis in what it acquired. In a tax-free reorganization under IRC Section 368, the seller receives mostly acquirer stock and defers gain until those shares are sold — but the buyer inherits the seller's old (carryover) basis instead of a stepped-up one. Neither is universally better; it depends on whether cash or stock is changing hands and which party values basis more.

Why do buyers and sellers fight over asset vs. stock deals?

A buyer generally prefers an asset deal because it gets a stepped-up, depreciable/amortizable basis and can leave unknown liabilities behind. A seller usually prefers a stock deal because it's taxed once at capital-gain rates rather than facing the double tax that hits a C-corporation asset sale. That structural tension is the core of most M&A tax negotiation.

Does a tax-free reorganization mean nobody ever pays tax?

No — 'tax-free' really means 'tax-deferred.' The seller postpones gain by taking acquirer stock and carrying over its old basis into those shares. When the shareholder eventually sells the stock, the deferred gain is recognized. Any cash or non-stock consideration ('boot') received in the deal is taxable in the year of the transaction.

How does entity type affect acquisition tax?

Entity type is decisive. A C-corporation asset sale is taxed twice — once at the corporate level on the gain, again when proceeds are distributed to shareholders. S-corporations and partnerships are generally pass-through, so an asset sale is taxed once at the owner level. That single difference frequently determines whether a deal is structured as an asset sale, a stock sale, or an election like Section 338(h)(10).
