How the DGT's position has evolved
Current position
The deductibility of passenger vehicle expenses requires their exclusive use for the economic activity, prohibiting partial use for private purposes. In renting contracts, the deductibility of installments is conditional upon compliance with the requirements of article 106 of the LIS (Corporate Income Tax Law). For sponsorship expenses, exclusive use allows for full deduction, whereas mixed use requires the application of a pro rata.
The DGT's position remains constant in requiring exclusive use for passenger vehicles, rejecting private use as an accessory. The doctrine has remained stable since 2015, limited to integrating the operation of renting contracts and the application of pro rata in cases of mixed use in sponsorship activities.
