Article 20.2.c) of Ley 29/1987 del ISD grants a 95% reduction (often increased to 99% by autonomous community legislation) on the value of qualifying family business participations transferred by inheritance or donation, subject to specific holding and activity conditions. The reduction applies to participations in operating entities meeting the family-business test of Article 4.Ocho LIP.
In cross-border situations — non-resident heirs, foreign-located business operations, multi-jurisdictional family groups — applying the reduction requires careful work. The DGT has issued substantial 2023–2026 doctrine on these issues, which we summarise here.
The Article 20.2 LISD family-business exemption is the most valuable single item in Spanish ISD planning — and the most factually intensive to qualify for.
The family-business exemption requires (i) the participation to be in an entity carrying on an economic activity (not a patrimonial entity, where 50%+ of assets are not affected to economic activity); (ii) the deceased or donor to have held at least 5% individually or 20% as a family group; and (iii) the deceased or donor (or a family member) to have performed management functions deriving more than 50% of total earnings from the activity. For inheritances, the heir must hold the participations for at least 5 years post-acquisition.
For cross-border situations, the conditions look to substantive economic facts regardless of where the entity is incorporated. A foreign operating entity meeting the conditions qualifies for the reduction. A foreign holding entity below an operating entity is analysed via consolidation under Article 4.Ocho.dos LIP. The autonomous community connection-point determines the applicable reduction percentage (typically 95% or 99%).

Notes from real cases · International Inheritance Spain
The exemption requires substantive operating activity (not patrimonial entity status), family-aggregate ownership thresholds, and management functions deriving 50%+ of total earnings from the activity. For cross-border family groups with foreign operating entities, each condition needs documentation in a form that survives a Spanish inspection — typically apostilled and translated.
Common pitfall: Pre-mortem structuring of the family business to qualify for the exemption is materially easier than post-mortem regularisation. Once the death occurs, the structure is frozen and the qualifying conditions are tested as they then stand.
If you advise a Spanish-connected family business, build the qualifying-conditions documentation into the annual operational running. Board minutes, payroll evidence, share registers — they should all be readily producible at any point in time.
