How the DGT's position has evolved
Current position
The tax neutrality regime allows capital gains not to be integrated into corporations or partners, maintaining the values and seniority of the assets. For its application, the transaction must have a commercial scope and comply with the requirements of the LIS (Corporate Income Tax Law), such as proportionality in the allocation of shares. In spin-offs, the transfer of a business line that constitutes an autonomous economic unit is required. The regime is denied if the main objective is fraud, tax evasion, or a spurious tax advantage.
The DGT's position has moved from treating the exemption of capital gains in the context of foreign holdings (V2528-14) to focusing on tax neutrality in business reorganization transactions. Recent rulings (V0003-26, V0906-26, V5244-26) have consolidated the requirements for economic substance, especially the need to transfer a business line with its own autonomy in spin-offs.
