How the DGT's position has evolved

Settled doctrine High confidence 59 rulings · 2017–2026

Current position

To apply the 95% reduction under article 20.2.c) of the LISD (Inheritance and Gift Tax Law), assets must be exempt from Wealth Tax as they are necessary for the habitual activity and the main source of income of the deceased. The acquisition must be mortis causa by a spouse, descendants, or adoptees, consolidating full ownership and maintaining the acquisition for ten years. Present succession agreements do not meet this requirement as the death does not occur at the time of the transfer.

The DGT's position remains constant in the interpretation of the requirements for the reduction under article 20.2.c) of the LISD. It has been reaffirmed that present succession agreements, although they are mortis causa acquisitions, do not access said reduction due to the lack of death of the deceased at the time of the transfer. The doctrine focuses on the necessity of death being the triggering event for the application of tax benefits.

Turning points

  1. V1132-21

    Establishes that present succession agreements do not meet the requirement for the reduction under article 20.2.c) as death does not occur at the time of the transfer.

  2. V0593-24

    Reiterates that succession agreements are succession titles but excludes the application of the reduction under article 20.2.c) and the reduction for inter vivos acquisition under article 20.6 of the LISD.
