How the DGT's position has evolved
Current position
Financial expenses from debt intended to acquire entities that join a tax group are subject to an additional limit of 30% of the acquirer's operating profit, excluding the profit of the acquired entity. This special limit applies prior to the general limit of 30% of the group's operating profit or the one million euro threshold. Tax late-payment interest is considered a deductible financial expense due to its compensatory rather than punitive nature.
The DGT's position remains stable regarding the classification of late-payment interest as deductible financial expenses. However, the doctrine has incorporated clarifications on the application of specific limits for debts related to the acquisition of entities within tax groups, establishing an order of application for these limits.
