How the DGT's position has evolved
Current position
SICAV mergers may benefit from the tax neutrality regime under Chapter VII of Title VII of the LIS if they are carried out for commercial purposes, comply with article 76.1, and respond to valid economic reasons without seeking fraud. Regarding Personal Income Tax (IRPF), shareholders may apply the income deferral if the requirements of article 94.1.a) of the LIRPF are met, considering for the 5% limit the accumulated participation in both the absorbing and the absorbed entity during the previous 12 months.
The DGT's position remains constant regarding the applicability of the special merger regime provided that valid economic reasons exist. Technical aspects have been specified concerning the integration of income in non-resident entities and the calculation of participation for IRPF deferral. No change in criterion is observed, but rather an application of the rule to scenarios of greater technical detail.
Turning points
-
Establishes that the dissolution of a SICAV compartment does not constitute a merger or a spin-off, as the compartment is not considered an entity under the LIS.
-
Specifies that for the 5% participation limit in the IRPF deferral, the participation in the absorbing SICAV and that of the absorbed entity must be computed for the previous 12 months.
