F Reorganizations in a Medical Practice Sale: A Plain-English Guide for Physicians

Team meeting around a conference table at McCormick Law & Consulting in black and white
Quick answer: An F reorganization is a restructuring often used when a buyer acquires a medical practice organized as an S corporation. Before closing, the owners form a new holding company, the existing practice entity becomes its subsidiary and is converted to an LLC, and the buyer then purchases interests in that LLC. For tax purposes, the buyer can generally be treated as buying assets, which it prefers, while the sellers can preserve S corporation treatment and often roll equity on a tax-deferred basis.

This article is part of our complete legal guide to selling a medical practice.

Our firm represented the selling physician in a medical practice sale with a $9 million purchase price that included an F reorganization, an equity rollover, and a management services agreement. Whether these features are appropriate for a particular practice depends on its facts. The structure is common in private equity practice acquisitions, but it is unfamiliar to most physicians the first time they see it.

Why do buyers want an F reorganization?

Buyers generally prefer to buy assets because they receive a stepped-up tax basis they can depreciate or amortize. Buying stock of an S corporation does not provide that step-up on its own. An F reorganization lets the buyer acquire interests in an entity that is disregarded for tax purposes, which is generally treated as an asset purchase, without a direct asset sale by the practice.

How do the steps work?

  1. The practice owners form a new holding corporation, owned in the same proportions as the existing S corporation.
  2. The owners transfer all of their shares of the existing S corporation to the holding corporation. The holding corporation makes its own S election and elects to treat the old company as a qualified subchapter S subsidiary, with the effective dates coordinated so there is no gap in S corporation status.
  3. The old company converts to a limited liability company under state law. In a medical practice, the resulting entity must still satisfy applicable licensing and professional-ownership rules, which differ by state and entity type.
  4. In a separate, taxable transaction, the buyer purchases membership interests in the LLC, and any rollover is structured at the holding company or platform level. The F reorganization itself is complete before this step.

The exact sequence and elections depend on the transaction and must be planned with tax advisors. Where state professional-ownership or corporate practice rules apply, a lay buyer generally cannot own the converted medical entity, so the structure is adapted, for example by moving the non-clinical business into the MSO.

What should physicians review?

IssueWhy it matters
Tax resultThe allocation of price and treatment of any rollover should be modeled by your CPA before you agree
Entity historyPre-closing liabilities of the practice usually stay with the entity the buyer acquires, so indemnities and escrows matter
Contracts and enrollmentPayer contracts, Medicare enrollment, and licenses may require notices or updates even when the legal entity continues. A physician organization generally must report a Medicare change of ownership within 30 days, depending on the enrolled entity and the ownership changes involved.
TimingThe reorganization steps must be completed in order before closing, often on a tight schedule
Rollover documentsEquity issued as part of the deal carries its own terms, covered in our guide to rollover equity

Is an F reorganization right for every practice?

No. It is primarily a solution for S corporation sellers and buyers who want asset-purchase tax treatment. Practices organized as partnerships, LLCs taxed as partnerships, or C corporations face different structuring choices. The decision should be made with your tax advisor before the letter of intent is final.

Attorney insight: Physicians do not need to master the tax mechanics, but they do need to understand what they own at each step and what they are giving the buyer in exchange. We walk clients through the structure chart before the documents arrive, so the reorganization steps are not a surprise in the week before closing.
