Tax neutrality in partial demergers: the importance of the line of business

The application of the special tax neutrality regime in demerger operations is a critical point for corporate planning. The Dirección General de Tributos (DGT) has analyzed whether a partial demerger operation can benefit from the tax incentives provided in Law 27/2014 on Corporate Income Tax (LIS).

What the DGT has ruled

The central issue focuses on determining whether the described demerger structure meets the requirements of Chapter VII of Title VII of the LIS. The core of the analysis lies in the nature of the assets and rights that the segregating company transfers to the beneficiary company.

For the operation to remain within the neutrality regime, the regulations require that the segregated assets are not merely isolated assets, but rather constitute a coherent economic unit. The DGT focuses on the need for the segregation to affect a line of business that possesses its own autonomous organization.

What this means for you

If your company is considering a partial demerger, you must keep in mind that tax neutrality is not automatic. The main risk is that the Administration may consider that the segregation does not correspond to the division of a real line of business, which would result in the taxation of the capital gains generated in the operation.

The key to avoiding this tax impact lies in the ability to prove that what is detached from the parent company has an independent operational, technical, and human structure. The transfer of assets is not enough; the transfer of an organization that can function by itself is necessary.

What should be done

Before executing an operation of this type, it is necessary to perform a technical analysis of the structure intended to be segregated. It is fundamental to document the existence of a line of business with its own organization to support the application of the tax neutrality regime in the event of a possible inspection. Each corporate scenario requires a technical assessment of the assets and the organizational structure involved.
