How the DGT's position has evolved
Current position
For the application of housing reductions or disability exemptions, exclusive use must pertain to an identified and accredited natural person. In the scope of economic activity, the deductibility of vehicle expenses (passenger cars or SUVs) requires their exclusive use for professional purposes, without admitting incidental private use. This exclusivity must be proven through legally admissible means of evidence and the corresponding accounting records.
The DGT's position is heterogeneous because the rulings address different matters (IVA, IRPF, and Economic Activity). There is no single doctrinal evolution, but rather a constant application of the concept of exclusivity to prevent the application of tax benefits in cases of mixed or unidentified use. Regarding vehicles, the requirement of professional exclusivity is maintained to allow the deductibility of expenses.
Turning points
-
Specifies that use by a spouse does not nullify the disability exemption if it is proven that said spouse could have met the registration requirements.
-
Establishes that for SUVs, the exception for incidental private use does not apply, requiring exclusive use for the activity.
