How the DGT's position has evolved
Current position
The value of production for the tax profit under article 98.f) of the LIE is calculated by adding the turnover of the industrial activity plus the change in inventories of work in progress and finished goods. Industrial activity is identified through divisions 1, 2, 3, or 4 of the IAE. The turnover must include the cost of raw materials when they are acquired to be transformed and subsequently resold.
The DGT's position has remained constant since 2015. The criterion repeatedly defines the composition of the value of production and the use of divisions 1 to 4 of the IAE to identify industrial activity. No changes are observed in the calculation methodology or in the delimitation of the activity throughout the sequence.
