Introduction to the 150-0 B ter Contribution-Transfer Mechanism
The contribution-transfer scheme, codified in Article 150-0 B ter of the French General Tax Code (CGI), is a preferred tax technique for entrepreneurs wishing to sell their company shares while deferring the taxation of capital gains realized. This mechanism allows for deferral of taxation by first contributing the shares to a holding company, before proceeding with the sale of the latter. The objective is to optimize the tax treatment of the business transfer or exit by avoiding immediate taxation at the time of sale.
The Contribution-Transfer Mechanism: Operation and Conditions
The 150-0 B ter contribution-transfer is based on the contribution of shares of an operating company (the target company) to a holding company created or already legally existing, followed by the sale of the holding company’s shares. This operation allows deferral of the capital gain tax on the contribution, subject to compliance with several strict legal conditions.
Key Steps of the Mechanism
Contribution of shares: The entrepreneur contributes their shares to a holding company, which in return issues shares in their favor.
Sale of the holding company’s shares: The entrepreneur then sells the holding company’s shares to a third-party buyer.
Tax deferral: The capital gain realized on the contribution is not immediately taxed but deferred until the subsequent sale of the holding company’s shares.

Reinvestment of proceeds

Engagement in economic activity
The holding company must carry out a genuine economic activity or hold a stake in an operating company.

Control of the Holding Company: A Strategic Lever
Effective control of the holding company over the target company is a sine qua non condition to benefit from the tax deferral. This means the holding company must hold at least 50% of the voting rights and financial rights in the operating company. This requirement ensures that the holding is not a mere shell, but an intermediate entity integrated into the control chain.
This control also allows the entrepreneur to retain strategic influence over the operating company, facilitating asset management and preparation for the final sale. Control is verified at the date of contribution and must be maintained for a minimum period, generally 3 years, to avoid challenge of the tax deferral.
Conditions for Reinvestment of Funds and Their Implications
The tax deferral provided by Article 150-0 B ter is conditional on reinvestment of the proceeds from the sale of the holding company’s shares within 2 years. Reinvestment consists of injecting these funds into an economic activity, either by subscribing to the capital of an operating company or financing a genuine entrepreneurial project.
If this condition is not met, for example if the funds are distributed as dividends or placed in financial products unrelated to an economic activity, the tax deferral is revoked. The tax authorities may then require immediate payment of the initially deferred capital gains tax, plus late payment interest.
Potential Tax Savings for Entrepreneurs
The main advantage of the contribution-transfer mechanism is the deferral, or even reduction, of capital gains tax realized upon sale. Indeed, without this scheme, a direct sale of shares would trigger immediate taxation at the flat tax rate (PFU) of 30% (12.8% income tax + 17.2% social contributions).
By deferring taxation, the entrepreneur has greater cash flow to finance new projects, enhance the holding company’s valuation, or optimize wealth transfer. Moreover, if the holding reinvests in operating companies, the entrepreneur can benefit from significant fiscal and patrimonial leverage.

Concrete Examples and Numerical Data
According to a study by the Banque de France (2023), nearly 35% of French entrepreneurs using company sales employ legal structures including an intermediate holding to optimize their taxation.
For an entrepreneur selling shares valued at 5 million euros, the taxable capital gain could amount to 3 million euros. Without contribution-transfer, immediate tax at 30% would represent 900,000 euros. With a structure complying with Article 150-0 B ter, taxation can be deferred, allowing retention of this amount in cash to finance new investments.
Risks and Points of Vigilance
Tax audit: The tax authorities are vigilant regarding compliance with conditions, notably effective control and the genuine economic activity of the holding company.
Holding period: Failure to respect minimum holding periods may result in revocation of the deferral.
Mandatory reinvestment: Absence of reinvestment within the prescribed deadlines triggers immediate taxation with potential penalties.
Legal complexity: Implementation requires precise legal and tax advice, often from specialized firms.
Conclusion: A Powerful Tool Under Strict Conditions
The contribution-transfer mechanism provided by Article 150-0 B ter CGI offers French entrepreneurs an effective solution to defer capital gains tax on sales. By contributing their shares to a controlled holding and respecting reinvestment conditions, they can optimize cash management and finance new projects.
However, this tax optimization is framed by precise conditions: effective control of the holding, minimum holding period, reinvestment of funds in genuine economic activities. Failure to meet these criteria exposes to significant tax reassessment.
Verdict: For entrepreneurs with significant capital gains, the 150-0 B ter contribution-transfer is an essential tax lever, provided it is managed with rigor and expertise. Consulting a specialized tax advisor before any operation is strongly recommended.
