How the DGT's position has evolved
Current position
Operating profit for the application of the financial expense deductibility limit under Article 16 of the LIS (Corporate Income Tax Law) must not include financial components. Results derived from joint account contracts are assimilated to financial income or expenses and are excluded from operating profit. Interest from participating loans is considered a deductible financial expense subject to the 30% limit of operating profit.
The DGT's position remains constant in defining operating profit as a concept that excludes financial elements. Rulings confirm that both results from joint accounts and interest from participating loans must be treated as financial income or expenses, remaining outside the calculation of operating profit for the Article 16 limit.
Turning points
-
Establishes that operating profit must include the operating result of discontinued operations, applying the same adjustments as to the general result.
-
Clarifies that results from joint account contracts are assimilated to financial income or expenses and do not form part of the operating profit.
