Merging companies may subrogate negative tax bases

Business concentration operations require a rigorous analysis of their tax treatment to avoid unforeseen impacts on the tax burden of the entities involved. A recent resolution from the Directorate General of Taxes (DGT) clarifies the conditions under which mergers can benefit from tax neutrality and the management of accumulated tax losses.

What the DGT has ruled

The DGT establishes that, if a merger meets the requirements demanded by Article 76.1 of the Corporate Income Tax Law (LIS) and is carried out for valid economic reasons, the tax neutrality regime will apply. This treatment entails two fundamental consequences:

• Integration of income: The absorbed company will not have to integrate income derived from the transfer of its assets.
• Continuity of values: The absorbing company will maintain the acquisition values and the holding period of the transferred assets.

Regarding tax losses, the tax authority confirms that negative tax bases may be offset in the absorbing company in accordance with Article 84 of the LIS, provided that the offsetting of said bases does not constitute the primary objective of the merger operation.

What this means for you

For companies planning reorganization processes, this criterion confirms the feasibility of maintaining the tax efficiency of assets and accumulated losses. Tax neutrality prevents the mere transfer of assets through a merger from generating an immediate taxable event, protecting the entity's cash flow. Likewise, the possibility of subrogating negative tax bases allows the new business structure to leverage previous negative balances to reduce its future tax burden, provided that the operation has a real economic justification beyond tax savings.

What should be done

In the event of a merger operation, it is necessary to document the existence of valid economic reasons that justify the transaction. This is crucial to prevent the Administration from considering that the merger's sole purpose is the offsetting of negative tax bases. It is recommended to perform a prior analysis of the requirements of Article 76.1 of the LIS and Article 84 of the same law to ensure that the structure of the operation complies with current regulations and allows for the subrogation of negative balances.
