How the DGT's position has evolved

Settled doctrine High confidence 53 rulings · 2014–2026

Current position

Contributions to the protected assets of a person with a disability allow for a reduction of the taxable base of up to 10,000 euros annually per contributor, with a joint limit of 24,250 euros annually per asset pool. The establishment and subsequent contributions mandatory require a public document before a notary or a judicial resolution. Non-monetary contributions do not generate capital gains or losses for the contributor.

The DGT's position on the reduction for protected assets remains constant regarding limits and formality. Recent rulings reaffirm the need for a public document or judicial resolution for the validity of the contributions. No changes are observed in the applicable reduction thresholds.

Analysis based on 48 of 53 rulings with a stated position. Updated 23 September 2026.
