How the DGT's position has evolved
Current position
To apply the tax relief, the entity must carry out an industrial activity of producing tangible goods through a manufacturing process that transforms raw materials into products with different characteristics. In the case of meat butchery, the activity must be registered under the heading for industries of utilization and transformation. If the packaging includes sterilization or pasteurization, it is considered the manufacturing of preserves.
The sequence of rulings does not show a doctrinal evolution on a single concept, but rather addresses tax relief in entirely different regulatory areas (procedural, Corporate Income Tax (IS), Property Tax (IBI), Transfer Tax and Stamp Duty (IIVTNU), SOCIMI, and industrial activity). There is no trajectory of change or refinement applicable to the general topic of 'tax relief' due to the heterogeneity of the cases.
