How the DGT's position has evolved
Current position
The exercise of stock options constitutes employment income that accrues at the time the right is exercised. To apply the 30% reduction provided for in article 18.2 of the LIRPF (Personal Income Tax Law), the generation period between the grant and the exercise must exceed two years. Furthermore, this reduction must not have been applied to other income with a generation period exceeding two years in the five previous tax periods.
The DGT's position remains constant regarding the classification of this income as employment income and the requirements for the 30% reduction. The application of the twenty-fifth transitional provision for options granted before 2015 has been maintained, but the general criterion regarding the generation period and the five-year limit on prior application is uniform across all rulings.
Turning points
-
Clarifies the application of the twenty-fifth transitional provision for options granted before 2015, allowing the 30% reduction without the limit of the five previous tax periods.
