How the DGT's position has evolved
Current position
For the deductibility of renting in Corporate Tax (IS), the vehicle must be used for the activity, recorded in the accounts, and documentarily justified. Regarding VAT (IVA), after proving its use for the activity, a 50% degree of use is presumed for passenger vehicles, although a different percentage may be proven. The insurance integrated into the contract forms part of the lease tax base if the client does not have the authority to negotiate its conditions.
The DGT's position remains constant regarding the requirement of exclusive use for the deductibility of expenses in Corporate Tax (IS). However, the doctrine has specified the VAT (IVA) treatment, moving from the requirement of exclusive use to the application of a 50% presumption of use for passenger vehicles. It has also been clarified that insurance is part of the single lease service when the client lacks autonomy.
Turning points
-
Introduces a presumption of a 50% degree of use for passenger vehicles in VAT (IVA) once the use for the activity has been proven.
-
Establishes that insurance forms part of the lease tax base if the client cannot choose or negotiate its conditions.
