How the DGT's position has evolved
Current position
When taxable and exempt operations are carried out jointly, a separate deduction regime must be applied for each differentiated sector if they exist. In the absence of differentiated sectors, the pro rata rule applies, which may be general or special according to the IVA (Value Added Tax) Law. The determination of the tax base for the calculation of the deduction must be limited to the consideration that actually constitutes the basis of the operation.
The DGT's position remains stable regarding the technical application of differentiated sectors versus the pro rata rule. The analyzed rulings do not show a doctrinal change, but rather apply the concept to diverse scenarios such as non-profit entities, parapharmacy, subsidies, or loans. The doctrine is limited to confirming the deduction mechanics according to the nature of the activities.
