Engagement note: Tax treatment, §1202 eligibility, capital-gain treatment, accumulated-earnings considerations, and management-fee defensibility depend on the specific transaction terms, entity structure, documentation, implementation, and applicable law in effect at the time. Not every platform partner is engaged in every matter; partner involvement depends on the client’s facts, scope, advisor environment, and engagement needs. Clients may use their existing CPA, counsel, investment advisor, and family office; GTC™ coordinates the MSO-specific workstream with those advisors. Legal, tax, investment, insurance, and compliance conclusions remain with the applicable independent advisor.

Investment bankers, PE sponsors, and M&A counsel structure the deal. GTC™ structures the MSO workstream and coordinates the shareholder architecture around it.

Deal counsel structures the operating MSO at closing. The structure may pass legal review and may require separate annual documentation and examination-readiness support as facts evolve. And for SSTB shareholders — lawyers, physicians, dental and veterinary practice owners — professional-service income flows through with potential limits on §199A QBI treatment and high individual-rate exposure depending on the facts.

GTC™’s overlays are designed to address two gaps the deal alone may not fully address: the §482 substantiation framework on the management fee, engineered at formation and recalibrated annually, and an entity architecture calibrated to the shareholder’s ongoing rate exposure and exit horizon.

THREE STRUCTURAL MOMENTS WHERE THE OVERLAY MATTERS

First deal — recap proceeds and rollover equity structured at closing.

Operating years — ongoing EBITDA flowing through the structure.

Round two — exit mechanics evaluated at formation with the objective of improving exit flexibility and potential capital-gain treatment where the facts, documents, and applicable law support it.

Where supported by services, arm’s-length pricing, and advisor review, the structure may coordinate business economics through documented operating arrangements rather than relying only on traditional gift-transfer planning.

For sell-side bankers and M&A counsel: embedding the overlay pre-LOI strengthens the seller’s post-deal economics, supports cleaner diligence, and positions the round-two recap as an asset the deal team brings back to the same client.

Boundary: GTC™ supports the seller-side advisory team with a documented MSO workstream. It does not replace banker-led process control, buyer negotiations, or transaction counsel.

Entity form calibrated to estate, exit, and post-deal economics

The deal team structures the operating MSO; GTC™ is in those conversations because the MSO form drives whether the overlay can function. How the shareholder’s retained interest is then held is where GTC™’s overlay carries through. Entity form — LLC, LP, partnership, or C-corporation — is selected against the shareholder’s estate plan, exit horizon, and post-deal economic objectives.

Converting post-deal capital into wealth, EV growth, and audit-ready governance

Post-deal capital can sit idle, leak to inefficiency, or be deployed deliberately. The overlay converts post-deal economics into compounding wealth for the shareholder, EV growth at the operating business, and tax-efficient deployment — coordinated with documentation and governance calibrated to the regulatory environment (CPOM, bar rules, professional-practice ownership).

The standard structure supports the deal. GTC™’s overlay supports the deal — and the §482 substantiation through to exit — and the round-two architecture engineered at formation.

What the standard deal-level structure handles. What GTC™’s overlay adds.

The deal mechanics look similar at closing. The structural defensibility diverges over the operating years through the next recap.

✓   §482 substantiation discipline at deal, recalibrated annually through to exit

✓   Shareholder entity architecture calibrated to estate, exit, and post-deal economics

✓   Round-two design embedded at formation, not retrofitted at recap

Six points in the deal lifecycle. GTC™ is in the room at each one.

GTC™ enters before the structure is malleable and supports the structure annually thereafter. The product is the relationship from pre-LOI through to the next recap.

Year 5–7

Common recap or exit window. The structure is designed to support the next event.

MSO structures are often built at the deal and engaged only intermittently after close. GTC™’s model is annual.

GTC™ coordinates annually with the shareholder’s accounting firm, the operating business, and deal counsel — running annual §482 recalibration, governance discipline, audit-readiness review, and coordination across the broader plan. The structure remains designed to be defensible only when maintained. That is the moat.

An active wave. A significant under-addressed planning gap in middle-market.

Law firms are the most active wave right now. Approximately a dozen law firm MSO transactions closed in 2025 (per industry reporting), with Holland & Knight leading much of the top-of-market advisory work.

The middle-market firm — $5M to $50M in firm value — has not been touched yet. That is where the wave is going next, and where the structuring gap on the shareholder side is widest. The same framework applies wherever PE operates within regulatory constraints on professional ownership.

The shareholder’s post-deal income and retained-interest planning often aren’t coordinated with a wealth, tax, and exit architecture. SSTB rules limit §199A QBI relief on professional-service income. GTC™ coordinates the shareholder’s architecture alongside the deal — pre-deal and post-deal, where the facts and entity form support it.

— Law firms — the most active wave of 2025–26; bar rules force the MSO operating layer

— Medical practices and physician groups — PE-backed roll-ups since 2010; corporate-practice-of-medicine statutes create the same structural pattern

— Dental support organizations (DSOs) — continued PE consolidation

— Veterinary practice networks — regional roll-ups continuing

— Engineering, architecture, and consulting practices — earlier-stage PE interest

One hypothetical. Mechanics accurate to GTC™’s methodology.

A representative structuring pattern for a professional-services PE recapitalization — hypothetical client, real mechanics. Actual structuring reflects the specific transaction terms and shareholder facts; what follows illustrates how the overlays sit inside the broader deal architecture.

The structure above is an illustrative model based on a hypothetical transaction. Actual structuring reflects the specific transaction terms negotiated and the shareholder’s facts. Not a representation of any specific GTC™ engagement. §1202 qualification, capital-gain treatment, and any specific tax outcomes require proper structuring from inception, are subject to multiple conditions and limitations, and depend on fact-specific application of applicable law in effect at the time. Implementation in coordination with the client’s independent legal and tax counsel.

What GTC™ does not do.

Defining the lane matters. Below: the boundaries of GTC™’s engagement so that advisors, deal teams, and family offices understand exactly what GTC™ provides and what stays with the client’s independent counsel and tax advisors.

×   GTC™ does not provide legal opinions.

×   GTC™ does not prepare tax returns.

×   GTC™ does not replace the client’s CPA, legal counsel, investment advisor, or family office.

×   GTC™ does not guarantee tax outcomes, audit results, §1202 eligibility, capital-gain treatment, estate-tax results, or investment performance.

×   GTC™ does not implement structures without coordination with the client’s independent legal and tax advisors.

No outcome promises. No pre-packaged structures. Each engagement is evaluated against the client’s facts, advisor environment, documentation, implementation, and applicable law. The platform provides the architecture and the coordination; the conclusions remain with the client’s independent advisors.

Calibrated to where you are.

A single ask doesn’t fit every reader. Below: three entry points calibrated to where PE firms and M&A advisors are in evaluating MSO architecture for an active transaction or a recurring deal practice.
