How the DGT's position has evolved
Current position
The right to deduction is based on the foreseeable use of the goods, which must be justified by objective elements. If the use is altered before the investment good enters operation, the adjustment is carried out at once through Articles 99.Two and 114 of the IVA (Value Added Tax) Law. If the change occurs when the good is already in use, the adjustment is staggered according to Article 107. In the case of housing intended for sale that transitions to exempt leasing, a self-consumption of goods subject to IVA occurs.
The DGT's position remains constant in the application of adjustment mechanisms according to the timing of the change of use. The rulings have clarified the distinction between direct adjustment (before use) and staggered adjustment (during use), in addition to integrating the factual nature of the accreditation of use. No doctrinal shifts are observed, but rather a systematic application of the IVA Law to different factual scenarios.
Turning points
-
Establishes that the foreseeable use must be justified by objective elements and warns that a lack of evidence leads to the impropriety of the deduction.
-
Clarifies that in the case of works, the staggered adjustment only applies if they are considered improvement works that increase the value of the good.
