How the DGT's position has evolved
Current position
Mortis causa donation is classified as a succession title and not as an inter vivos transaction, applying the rules for acquisitions by reason of death. In Personal Income Tax (IRPF), it is considered a lucrative transfer by reason of death, which prevents estimating the existence of a capital gain or loss pursuant to Article 33.3.b). The tax accrues at the moment of the signing of the contract, but the reduction of Article 20.2.c of the Law on Inheritance and Gift Tax (LISD) is not applicable because the deceased has not passed away.
The DGT's position remains constant in classifying mortis causa donation as a succession title. Throughout the rulings, the application of Article 33.3.b) of the IRPF Law has been specified to exclude capital gains, and it has been clarified that accrual occurs upon signing, without this allowing access to reductions due to death.
Turning points
-
Distinguishes between mortis causa donation (succession title) and inter vivos donation with post mortem effectiveness (subject to a suspensive condition).
-
Links the non-existence of capital gains to the subjection of the transfer to a suspensive or resolutory condition.
