The F Reorganization: Why a Private Equity Buyer Will Ask Your S Corp to Do One First

What Is an F Reorganization, Actually?

An F reorganization is one of seven types of tax-free corporate reorganization, and the statute is unusually short. Section 368(a)(1)(F) defines the transaction as "a mere change in identity, form, or place of organization of one corporation, however effected."

Read that phrase carefully, because the whole benefit sits inside it. A mere change in form is not a sale, so there is nothing to tax. The words "however effected" are what give practitioners room to accomplish the change through the holding-company mechanics described below rather than through a single prescribed set of steps. In a deal context, it means your S corporation is reorganized into a new holding-company structure without triggering tax, so the operating business can then be sold as an LLC interest rather than as corporate stock.

The mechanics run in a specific order. The shareholders form a new corporation. They contribute their existing S corporation stock to it. The new corporation elects to treat the old one as a qualified subchapter S subsidiary, a QSub. The old corporation then converts to a single-member LLC. When the dust settles, you have a holding company that is still an S corporation, and beneath it a disregarded LLC that holds the operating business. This is exactly the structure the IRS validated in Rev. Rul. 2008-18, where the original S election continues for the new holding company and the old entity becomes a QSub.

The buyer then purchases LLC units from the holding company. That last step is what the whole exercise exists to enable: for tax purposes, buying units of a disregarded LLC is treated as buying the underlying assets directly.

Why Does the Buyer Want It?

A buyer who purchases corporate stock inherits your tax basis in the assets. If you have been depreciating equipment for eight years, the buyer inherits eight years of depreciation already taken and gets very little going forward. A buyer who purchases assets gets to write the purchase price onto the assets at their new value and depreciate or amortize from there.

The IRS states the principle directly. In its guidance on the sale of a business, it says the sale of a trade or business for a lump sum is considered a sale of each individual asset rather than of a single asset. That difference is worth real money. Goodwill in an asset purchase is amortizable over fifteen years; goodwill inherited in a stock purchase is not amortizable at all. On a deal where goodwill is the largest component of the price, and in service businesses it usually is, the buyer is looking at a deduction stream worth a meaningful fraction of the purchase price.

So the buyer wants an asset purchase. You, as an S corporation shareholder, face one level of tax either way, but that does not make you indifferent. In an asset sale, actual or deemed, part of the gain can be ordinary income from inventory and depreciation recapture, while a straight stock sale generally produces capital gain at the shareholder level. The aggregate tax on the same price can differ meaningfully between the two, which is why the seller models both before agreeing to the structure. The F reorganization is what lets both sides get most of what they want, priced correctly. This is the same asset-versus-stock tension covered in our guide on asset sales versus stock sales.

Why Did Buyers Move on From the 338(h)(10)?

There is an older route to the same outcome: a Section 338(h)(10) election, where both parties jointly elect to treat a stock purchase as an asset purchase for tax purposes. It works. It is also fragile in ways that matter when the target is a closely held S corporation.

The middle rows are the ones that ended the argument for most private equity buyers. An S election can be invalid for reasons nobody noticed for a decade: a second class of stock created by an unequal distribution, a trust that was never a permitted shareholder, a missing consent on the original Form 2553. The IRS is explicit that to become an S corporation, the corporation must submit Form 2553 signed by all the shareholders.

If the election turns out to be defective, a 338(h)(10) collapses. The F reorganization reduces the buyer's side of that risk, because the buyer ends up holding LLC interests rather than the historical corporation, but it does not make the defect irrelevant. Rev. Rul. 2008-18 describes an S corporation whose operating company becomes a QSub of a new S holding company; if the purported S election was never valid, the entity may actually be a C corporation, the QSub treatment may not work as assumed, and the corporate-to-LLC conversion can itself have tax consequences. A defective election can still materially change the seller's tax treatment and the restructuring steps, and it has to be resolved during diligence rather than assumed away.

This is the part most articles skip. The F reorg is not just tax-efficient. It reallocates risk. The buyer is reducing the S-election risk on their side of the table, while the seller keeps the consequences of any historical defect, which is why the diligence still has to be done.

Where Does This Go Wrong?

In the deals we have worked on, the F reorganization itself is rarely the problem. The problem is what nobody modeled. Three places, specifically:

• The step-up gets negotiated after it is already assumed. The buyer prices the deal knowing they get amortizable goodwill. That benefit is worth something specific and calculable. Sellers almost never ask to share it, because by the time they learn what an F reorg is, the price is already agreed. Ask earlier.
• State taxes do not follow federal treatment automatically. New Jersey and New York do not always treat a restructuring the way the federal rules do, and a multi-state business can create filings in states nobody considered. This is the most common surprise in the deals we see across the Hackensack and New York City corridor.
• The timeline collides with exclusivity. An F reorganization involves entity formation, a QSub election, an LLC conversion, and state filings. None of it is slow in isolation. All of it is slow when it starts three weeks before a closing date that is already in the purchase agreement.

What Does It Cost, and What Is It Worth?

We are not going to publish a fee for this, because the honest answer is that the cost scales with how complicated your entity history already is. What we will do is tell you what drives it. The cost drivers, in rough order of impact: entity history (one corporation, one state, the same shareholders throughout is straightforward; a partial redemption, a shareholder death, and a state redomestication is not), number of states with nexus, legal drafting (contribution agreements, the QSub election, the LLC conversion documents), tax modeling (quantifying the step-up, allocating the price, modeling the rollover), and timeline pressure (work compressed into an exclusivity window costs more).

The one number worth internalizing is the comparison, not the fee. On a deal of any size, the value of the amortizable goodwill the buyer receives is materially larger than the cost of the restructuring that creates it. That asymmetry is exactly why it is worth negotiating over.

Our view, stated plainly: that is negotiable, and sellers almost never negotiate it. Not because the ask is unreasonable, but because the term arrives late, sounds procedural, and gets waved through with the other closing mechanics. Raise it while price is still open.

How Does the Rollover Fit In?

Most private equity buyers in the lower middle market ask the seller to roll a portion of their proceeds into the new company rather than take all cash. Ten to thirty percent is the common range. Here is where the structure earns its keep a second time.

If you try to roll equity while the target is still an S corporation, you can create problems fast. The new investor may not be an eligible S corporation shareholder. The rolled interest may carry different economic rights, which can be treated as a second class of stock. Either one terminates the S election, and terminating it mid-transaction is an expensive way to learn the rule. Rolling at the LLC level avoids that entirely, because an LLC has none of those shareholder-eligibility constraints. That is why the F reorganization and the rollover almost always appear in the same deal: one makes the other clean. The tax treatment of the rollover itself is a separate question with real consequences, covered in our guide on how rollover equity is actually taxed, and it is worth understanding before you agree to a percentage rather than after.

How Does the Purchase Price Get Allocated?

Once the transaction closes as an asset purchase for tax purposes, both sides have to agree how the price is spread across asset classes and report it consistently. The IRS requires the residual method: except for assets exchanged under nontaxable exchange rules, both the buyer and seller must use it to allocate the consideration to each business asset transferred.

That allocation is reported on Form 8594, filed by both parties. It is not a formality. The split between equipment, intangibles, non-compete, and goodwill changes the tax outcome for each side in opposite directions, which is why it gets negotiated rather than calculated. Sellers generally want more of the price allocated to goodwill, which is capital gain; buyers generally want more allocated to assets they can depreciate quickly. Each side files its own Form 8594, and the two filings generally need to be consistent, because an inconsistency between them is visible to the IRS. The mechanics are covered in depth in our guide on the basis step-up and purchase price allocation.
