Tax neutrality in partial demergers: the requirement of a business line

The application of the tax neutrality regime in partial demerger operations is a critical aspect of corporate planning. The Dirección General de Tributos (DGT) has specified the requirements necessary for these operations to avoid incurring Corporate Income Tax (IS) on the transfer of capital gains.

What the DGT has ruled

According to the Corporate Income Tax Law (LIS Law 27/2014), for a partial demerger to be considered tax-neutral, the mere transfer of assets and liabilities is not enough. The criteria establish that the segregated elements must constitute a business line with its own organization. This requirement is decisive to prevent the operation from being classified as an ordinary transfer of assets, which would trigger taxation on the capital gains generated during the process.

What it means for you

For companies considering restructuring processes through partial demergers, this criterion implies a technical compliance burden. Neutrality is not automatic simply by performing the operation under the legal form of a demerger. If the assets and liabilities being transferred do not have an organizational structure capable of operating autonomously, the Tax Administration could consider that the business line condition has not been met, demanding the payment of the corresponding tax on the market value of the transferred elements.

What should be done

In the event of such an operation, it is necessary to conduct a technical analysis of the structure of the elements intended to be segregated. It must be verified that the transferred economic unit possesses sufficient human, material, and organizational resources to function independently. Assessing each case individually is fundamental to ensure that the operation strictly adheres to the requirements of the Corporate Income Tax Law and to avoid future tax contingencies.
