Why Buyers Request an F Reorganization Before Closing

The tension the F reorg solves

In almost every acquisition of a closely held company, the buyer and seller want opposite things structurally. The seller generally prefers a stock sale: it's simpler, it avoids re-titling contracts and licenses, and if the target is an S corporation, a stock sale can qualify the seller's gain for capital gains treatment cleanly. The buyer generally prefers an asset purchase, because it gets a stepped-up tax basis in the acquired assets, meaning larger depreciation and amortization deductions going forward, and it leaves unknown liabilities behind in the old entity.

An F reorganization, paired with a Section 338(h)(10) or Section 336(e) election, lets both sides get what they want. The deal is legally structured as a stock purchase, but it's taxed as if the buyer purchased the target's assets.

How the sequence actually works

• Before closing, the seller's shareholders form a new holding corporation and contribute their target company stock to it, in an F reorganization.
• The target (now a wholly owned subsidiary of the new holding company) converts into a disregarded entity, typically a single-member LLC or a QSub if the structure involves an S corporation.
• At closing, the buyer purchases all of the stock of the new holding company, not the underlying operating entity directly.
• Because the acquired entity is disregarded for tax purposes, the stock purchase is treated, for federal income tax purposes, as if the buyer bought the target's assets directly.

Legally, it's a stock sale: one set of shares changes hands, existing contracts and licenses generally don't need to be assigned, and the corporate entity itself doesn't need to be dissolved. For tax purposes, it's treated as an asset sale, giving the buyer the basis step-up it wants.

Why this often shows up specifically with S corporations

This structure is especially common when the target is an S corporation, because a Section 338(h)(10) election is available for S corp stock sales without needing a corporate buyer group, and because converting the target into a QSub inside the F reorg preserves the practical benefits of the S election right up until closing. See F reorganizations for S corporations for how this plays out in rollup and private equity transactions specifically.

What it means for the seller

Done correctly, the F reorganization itself doesn't change the seller's tax outcome. The gain on the sale is still computed the same way; what changes is that the buyer typically pays a modestly higher purchase price in exchange for the step-up, since it's worth real money to the buyer going forward. Sellers should expect this to come up in negotiation, and should have their own tax counsel review the specific mechanics rather than relying solely on the buyer's proposed structure.
