What is an internal capital gain?
An internal capital gain arises when an individual contributes or sells the shares of their company to another company they also control, usually a holding company set up for the purpose. The gain is internal because it is realised within the same economic estate: the seller remains, indirectly, the owner.
The aim is twofold: to move value up into an asset-holding structure, and to turn a shareholding into a receivable or capital that can be drawn on. It is precisely this absence of any real economic change that draws the tax authorities' attention.
The tax regime and how it has changed
The principle remains that a capital gain on shares realised by a private individual as part of the normal management of their private assets is not taxable. It is on this basis that contribution-and-sale transactions long flourished.
The tax authorities now take the view that a transaction with no economic substance of its own falls outside this normal management. The gain can then be requalified as miscellaneous income and taxed at 33%, plus municipal surcharges, or even treated under other regimes depending on the structure.
The framework has also evolved with recent discussions on taxing capital gains on financial assets. Any analysis must be based on the law applicable on the date of the transaction, not on a scheme seen elsewhere a few years earlier.
What the tax authorities examine
The central criterion is substance: does the transaction serve a genuine economic or estate-planning purpose, separate from the tax advantage it brings?
- A documented non-tax reason: succession, a new partner coming in, a reorganisation, financing an acquisition.
- The valuation used, which must come from a defensible method and not from a comfortable figure.
- How the transaction is financed and what actually happens to the price or the receivable.
- The holding company's real activity after the transaction, as opposed to a dormant shell.
- The timeline, since a sale closely followed by a large distribution is scrutinised particularly closely.
Why go through a ruling
The Advance Rulings Service (Service des Décisions Anticipées, SDA) issues, before the transaction, a decision that binds the tax authorities on the intended tax treatment. It is the only way to obtain real legal certainty on an internal capital gain.
The process requires a well-supported file and time, and it means accepting that the answer may be negative or conditional. That is the price of certainty: going ahead without a ruling amounts to betting on how a future audit will interpret the transaction, with back taxes and surcharges if you get it wrong.
Not to be confused with
The terms close to Internal capital gain and what sets them apart.
- Internal capital gain and a sale to a third party
- A sale to an independent buyer takes the shareholding out of the seller's estate and does not raise the question of substance. An internal capital gain is characterised by continued control.
- Internal capital gain and the liquidation reserve
- The liquidation reserve is an explicit statutory regime for taking profit out at a reduced rate. An internal capital gain is not a regime: it is a transaction whose treatment depends on its substance.

Internal capital gain: frequently asked questions
The gain realised by selling or contributing the shares of your company to a holding company you control yourself. It is called internal because the seller remains indirectly the owner: the transaction does not change economic control.
It can be. The principle that capital gains arising from the normal management of private assets are not taxed still stands, but a transaction with no economic substance of its own can be requalified as miscellaneous income taxed at 33%, plus municipal surcharges.
It is an advance decision from the Advance Rulings Service, issued before the transaction and binding on the tax authorities. It is the only way to obtain real certainty about the tax treatment of an internal capital gain.
The transaction is not prohibited, it is regulated. It requires genuine economic substance and, in practice, an advance ruling. Copying a structure seen a few years ago without re-examining the applicable law is the main risk.
Payment of the tax avoided, plus surcharges and late-payment interest. The cost then far exceeds the saving sought, which explains why a ruling is the norm for this type of file.
