Holding company after company buyout: 150-0 B ter case study

Updated May 12, 2026 — reviewed by Samuel HAYOT, chartered accountant. You have just bought a company directly (acquisition of a business, a firm or shares) and several advisers are now suggesting you set up a holding company after the fact: to upstream dividends more efficiently, to prepare another buyout, to anticipate a sale in 3 to 5 years. This article does not revisit the definition of a holding company — see holding company: advantages and disadvantages for the upstream decision. It documents the typical post-buyout case we handle in the firm: timing, conditions of the 150-0 B ter regime (capital gain deferral on a securities contribution), tax consolidation, and the points of vigilance that change the quality of a file in front of the French tax authority (DGFiP).

Client situation. A manager buys 80% of an operating SARL for EUR 1.2M, financed half equity, half bank debt. Six months later, he is considering a second acquisition and wants to avoid mixing the flows of the two targets. The question is no longer "is the holding company relevant" (it is — two companies justify a group parent) — the question is when to interpose it, through which mechanism and with what documentation.

Three possible trajectories (and their tax implications)#

Our reading. In 8 out of 10 files of this kind, we recommend trajectory A — but only if the manager is ready to comply with the 60% reinvestment within 24 months in case of a partial sale. Without that projected commitment, the deferral becomes a trap rather than an advantage. Trajectory C is the easiest to defend but does not address the company already bought.

The schedule of the operation#

The moment when the holding company is created changes the way flows, financing and any tax deferrals are read. A holding interposed before the buyout, at the buyout or several months later does not produce the same effects, nor the same evidence requirements.

The contribution of shares or reorganisation#

Article 150-0 B ter CGI and its BOFiP doctrine govern contributions of shares to a company controlled by the contributor, with strict monitoring of the deferral and the reinvestment obligations that may follow. The doctrinal framework is rich and case-by-case: each contribution must be documented on the date, the perimeter and the projected use of the proceeds.

The economic function of the holding company#

A useful holding company must have a readable role: to hold, finance, animate, organise a group or prepare a transmission. When that role is absent, the structure looks artificial — and the tax administration tends to follow that perception.

• Setting up a holding company after the fact without clear economic logic;
• Forgetting the deadlines and conditions of the 60% reinvestment;
• Underestimating the documentation requirements (minutes, contribution report, intragroup agreements);
• Treating the subject as a simple cash optimisation;
• Failing to plan the bank refinancing of the buyout loan inside the holding architecture;
• Mixing professional and personal flows in the same vehicle once the holding is set up.

Hayot Expertise advice: a post-buyout holding company is not absurd if it answers a genuine group logic. It becomes fragile if it is created only to capture a poorly managed tax advantage.

Setting up a holding company after a buyout only makes sense if it solves a concrete situation. For instance, it can isolate the holding of the shares, prepare a new investment cycle, organise a transmission or make it easier to upstream cash between several assets. Without that need, the post-buyout creation looks more like a legal repainting than a real strategy.

The right reasoning starts from the overall project. If the buyout was financed directly, you need to ask what the holding company will actually add: a clearer view of flows, leverage to reinvest, a steering structure or a framework for further acquisitions. If the answer remains vague, it is wiser to slow down. A holding created out of pure imitation rarely survives its first audit.

Let us imagine a manager who buys an operating company and, a few months later, wants to launch a new activity, keep part of the profits inside an intermediate vehicle and prepare for possible external growth. In that case, the holding company can act as a group parent — but only if the flows are clearly organised and the contribution mechanism is properly documented.

Timing is the critical point. If the holding is set up too late, it may be more difficult to justify certain tax choices or to reorganise the relationship between the bought company and the parent company. If it is set up too early without a documented project, it risks being useless. The right timing sits between inertia and haste, and depends heavily on the buyout financing structure and on the maturity of the second project.

A useful intermediate step is to model the next three years: projected dividends, debt service of the buyout loan, capacity to refinance, and reinvestment scenarios. Once those numbers are on the table, the right calendar usually becomes self-evident.

Before building the scheme, you have to verify:

• who owns what, and at which date;
• which flows will be upstreamed to the holding company;
• whether there is a clear reinvestment logic identified for the next 24 months;
• whether a service or management agreement is needed (and at what price);
• whether the operation belongs to a wealth-management logic or a group logic;
• how the existing buyout debt fits with the new holding architecture;
• whether tax consolidation (integration) is a realistic option, given the 95% ownership threshold.

These questions look technical, but they condition the strength of the file. A post-buyout holding company must show its economic function in a simple and defensible way. Only after this reading can taxation be discussed seriously.

Article 150-0 B ter of the French General Tax Code (CGI) and the BOFiP doctrine govern contributions of shares in specific configurations. That means you cannot reason only in terms of convenience. The creation date, the contribution terms, the control exercised over the holding, any reinvestment obligations and the documentation must be reviewed together.

In a real file, the advice is often to verify future flows before restructuring. If the holding company receives no identifiable flow, it brings little. If it is meant to capture group income, finance a future acquisition or organise a transmission, it becomes much more credible. The same goes for the parent-subsidiary regime (régime mère-fille), which only delivers its full value when the dividend flows are real, regular and properly traced.

When a partial sale of the contributed shares is contemplated within 3 years, the 60% reinvestment obligation becomes the heart of the analysis. Eligible reinvestments are strictly defined by the BOFiP doctrine (operational acquisitions, qualifying funds, financing of operational activities). Failing to reinvest properly triggers the loss of the deferral and the immediate taxation of the latent capital gain — usually with late interest.

This table helps sort the strong cases from the weak ones quickly. The more precise the answers, the more defensible the post-buyout creation becomes. In our experience, the files that hold up to a later tax review are always those where the table can be filled in writing, not orally.

It is often better to wait if the buyout has just been finalised, if the flows are not yet stable or if the project does not yet have a clear direction. In those cases, the manager should first observe the real flows, the target's profitability and the reinvestment capacity before freezing the structure.

Waiting does not mean giving up. It simply means the holding company should come at the right time. A structure built too fast can block future options, whereas a structure built after analysis can become a much more robust steering tool. In several files we have followed, postponing the holding by 6 to 9 months allowed us to integrate a second acquisition under far cleaner conditions — both legally and bank-wise.

Before freezing the scheme, it is often useful to run a simple test: if you remove the tax argument, does the holding company still have an economic purpose? If the answer is yes, the project is probably solid. If the answer is no, the calendar, the target and the function of the structure should be reviewed.

In post-buyout files, that test avoids building a "paper" holding company. It also forces you to clarify three points: the need for steering, the reinvestment path and the place of the holding company in the future organisation. When those three elements are clear, the scheme becomes much more robust — and much easier to defend in the event of a control by the DGFiP.

We model the flows, the ownership, the tax effects and the reorganisation scenarios to validate whether a post-buyout holding company makes sense. Our approach combines a chartered accountant's reading (accounts, financial projections, dividend capacity) with a legal review of the bylaws, intragroup agreements and reinvestment plan. When the file requires it, we work with a partner law firm on the 150-0 B ter documentation.

In 2026, creating a holding company after a buyout can be relevant, but only if the reorganisation serves a clear patrimonial and economic objective. The right scheme depends on the calendar, the flows and the documentation. The 150-0 B ter regime, the parent-subsidiary regime and the tax consolidation regime are powerful — provided they are used in a real group logic, not as an after-the-fact tax wrapper.
