Merger-absorption: procedure, taxation and vigilance

Updated March 2026 - Merger-absorption allows one company to absorb another with universal transfer of assets and disappearance of the absorbed company. Behind this fairly well-known definition, the operation remains technical. It involves corporate law, taxation, accounting, legal documentation and a strict timetable. A poorly prepared merger-absorption can weaken the balance between partners, delay the operation or produce unanticipated tax effects.

In a merger-absorption:

• ▸one company absorbs another;
• ▸the assets are transmitted to the absorbing party;
• ▸the absorbed disappears;
• ▸securities or compensation are allocated according to the chosen scheme.

The legal framework is mainly based on the Commercial Code, with precise formalities and special cases depending on the structure of the operation.

A merger-absorption operation supposes in practice:

• ▸a preliminary analysis of the objectives;
• ▸verification of the scope and impacts;
• ▸preparation of the merger project;
• ▸compliance with formalities and deadlines;
• ▸management of accounting, tax and social effects.

Taxation: a subject to be dealt with very early

The transaction may fall, under conditions, under the special merger regime referred to in particular in article 210 A of the CGI. This aspect must never be treated downstream, because it conditions:

• ▸the desired fiscal neutrality;
• ▸the treatment of certain assets and capital gains;
• ▸carryovers and commitments;
• ▸the necessary documentation.

Hayot Expertise Advice: a merger-absorption is first prepared as a global project. Legal, tax and accounting must be aligned from the design phase.

• ▸economic and logical value of the operation;
• ▸calendar of decisions;
• ▸debt, cash and off-balance sheet commitments;
• ▸compatibility with the target organization;
• ▸securing tax effects.

A merger-absorption may concern:

• ▸group simplification;
• ▸a reorganization;
• ▸a transmission;
• ▸rationalization of activities.

But the challenge is not only to “do” the merger. It must produce the desired result, without any documentary or fiscal blind spots.
