For business owners selling their company, the apport-cession mechanism under article 150-0 B ter of the French Tax Code has been, since 2012, one of the most powerful wealth structuring tools available in French tax law. By contributing shares to a holding company prior to the sale, the business owner defers tax on the capital gain — avoiding the immediate flat tax (PFU) of 30%. France’s 2026 Finance Act, adopted on 2 February under article 49.3 of the Constitution, did not dismantle this fundamental mechanism, but significantly hardened its conditions, with effect for disposals from 21 February 2026.

As the spring 2026 M&A season gets underway, understanding the impact of these new rules — and planning the reinvestment strategy accordingly — has become an absolute priority for any business owner engaged in a sale or succession process.

The Apport-Cession Mechanism: A Brief Overview

Article 150-0 B ter of the French Tax Code organises the deferral of capital gain taxation on the contribution of shares to an IS-paying company controlled by the contributor. The mechanism operates in two stages.

In the first stage, the business owner contributes operating shares to a holding company. The contribution gain is recognised but its taxation is deferred — it only becomes payable upon triggering events (sale of shares received in exchange, dissolution of the holding company, or relocation abroad without justification). In the second stage, the holding company sells the contributed shares to the final acquirer: this sale generates the cash available for reinvestment.

The liquidity advantage is considerable. For a business owner realising a gain of €3 million, immediate PFU taxation represents approximately €900,000 in tax. Under the apport-cession structure, this sum remains available within the holding company for investment, generating returns on full capital throughout the deferral period.

What Has Changed Since 21 February 2026

The Reinvestment Ratio Raised to 70%

Under the previous regime, when the holding company sold the contributed shares within three years of the contribution, it was required to reinvest at least 60% of the sale proceeds in eligible operating activities. The 2026 Finance Act raises this threshold to 70%.

The impact is immediate and mechanical. For a holding company receiving €5 million on disposal, the reinvestment obligation rises from €3 million to €3.5 million. The remaining 30% — i.e. €1.5 million — can be freely managed by the holding company (cash, financial investments, distribution), but the gain deferral only covers the 70% reinvested fraction.

The Reinvestment Window Extended to 3 Years; Holding Period Extended to 5 Years

The 2026 Finance Act introduces two simultaneous changes with opposing effects. On one hand, the deadline to reinvest the 70% is extended from two to three years from the date of disposal. This additional flexibility is welcome for identifying and structuring quality investments — owners are no longer forced to invest in haste.

On the other hand, the minimum holding period for reinvested assets is drastically extended: from 12 months to 5 years. In other words, SME shares or fund units subscribed as reinvestment must be held for five years, or the gain deferral is reversed. For a disposal completed in 2026, reinvestment assets must be held until at least 2031.

Eligible Activity Scope Narrowed

The 2026 Finance Act now explicitly excludes certain activities from eligible reinvestment targets. Those targeted include real estate development and property trading — sectors that had absorbed a growing proportion of reinvestments in recent years, drifting away from the original objective of supporting productive economic activity.

Eligible targets remain: subscriptions to the capital of operating companies (SMEs, mid-caps), investments via FCPR, FPCI or SLP funds meeting legal requirements, as well as certain direct co-investments in industrial or technology projects. The selection of reinvestment vehicles now demands careful legal and tax analysis.

A Worked Example: The Impact of the Reform on a Real Case

Consider a business owner selling an industrial group for proceeds of €8 million, with a contribution gain of €6 million.

Under the old regime (disposal before 21 February 2026): the holding company had to reinvest €4.8 million (60%) within two years, with a minimum 12-month holding period. The €4.8m could be spread across direct SME investments, FCPR funds and real estate co-investments.

Under the new regime (disposal from 21 February 2026): the holding company must reinvest €5.6 million (70%) within three years, with a minimum 5-year holding period. The additional reinvestment effort amounts to €800,000, and eligible investment options are restricted to non-real estate operating assets with a long-term horizon. In practice, this requires access to private equity managers, venture capital advisors or privileged deal flow — something that only professionally accompanied wealth structures can realistically orchestrate.

Adaptation Strategies: Navigating the New Framework

Plan the Reinvestment Strategy Before Signing

The most demanding constraint of the new regime is not the 70% ratio per se — it is the five-year holding period combined with the exclusion of real estate. Reinvesting 70% of disposal proceeds in non-listed, illiquid assets held for five years requires a pre-built portfolio construction plan, not a decision made under post-closing pressure.

Best practice is to initiate the reinvestment strategy six to twelve months before the sale: identifying compatible private equity funds (FCPR, FPCI, SLP), evaluating direct co-investment opportunities in industrial or technology SMEs, and structuring a binding subscription letter synchronised with the closing of the disposal.

Diversify Reinvestment Vehicles Over Time

The extended three-year window opens a gradual diversification opportunity. Rather than concentrating all reinvestment in a single vehicle at closing, it is now possible to adopt a phased approach:

• First tranche (year 1): subscription to a diversified SME-focused FCPR for 40-50% of the mandatory reinvestment amount
• Second tranche (years 2-3): targeted direct co-investments — equity stakes in regional operating SMEs, or sector-specific funds (deep tech, industrial, healthcare)

This approach allows for optimised asset selection while fully respecting the legal deadlines. It requires rigorous documentary tracking — each reinvestment must be traced, dated and legally qualified.

Do Not Neglect the 30% Free Fraction

The portion not subject to reinvestment obligation — 30% of sale proceeds — is not negligible. Within the holding company, these liquid assets can be invested in securities (equity funds, bonds, structured products), Luxembourg capitalisation contracts, or held as remunerated cash. Managing this liquid pocket is straightforward wealth management, free from holding constraints, and typically represents the first short-term yield driver for the holding company.

Frequently Asked Questions on Apport-Cession in 2026

Is my reinvestment commitment signed before 21 February 2026 affected?

No. The new rules apply to disposals of contributed shares carried out from 21 February 2026 onwards. If the disposal occurred before that date, the old regime (60%, 2-year window, 12-month holding) continues to apply. The tax administration has not applied any retroactive effect.

Can I reinvest in my own new operating company?

Yes, under conditions. Reinvestment in a newly created operating company is eligible, provided the company carries on a commercial, industrial, craft, liberal or agricultural activity and is not predominantly real estate. The holding company must ensure that the subscription is made to share capital — not a shareholder loan — and that the five-year holding period is observed.

Does the three-year window run from the contribution or the disposal?

The window runs from the disposal of the contributed shares by the holding company (not from the contribution date). It is the proceeds of the holding company’s disposal that must be 70% reinvested within three years of that disposal.

What happens if the holding company fails to meet the 70% threshold within the deadline?

A breach of the deferral conditions triggers immediate taxation of the deferred gain, plus late payment interest (0.20% per month). In the case of deliberate non-compliance, a 40% surcharge may also apply. The tax exposure is therefore substantial, which justifies a contractualised reinvestment tracking plan.
