How the DGT's position has evolved
Current position
The excess of tax paid abroad that is not deductible from the gross tax liability due to exceeding the limit thereof shall only be a deductible expense if it corresponds to the performance of economic activities in the source State. For economic activity to exist, the entity must have personnel or fixed establishments in said country.
The DGT's position remains constant regarding the deductibility of excess foreign tax. The rulings of 2022 and 2023 confirm that the excess over the Convention limit does not allow for the application of article 31 of the LIS (Corporate Income Tax Law) and that deductibility as an expense requires real economic activity abroad.
