How the DGT's position has evolved
Current position
SOCIMIs must include in their tax base the real estate income obtained through permanent establishments of entities under income attribution regimes, such as French SCI or SNC, for the calculation of the income ratio. The contribution of assets and liabilities may be carried out through the non-monetary contribution of a business line if it constitutes an autonomous economic unit. For this operation to be valid, it is not necessary to contribute all properties or the management company, provided that the activity is maintained under analogous conditions.
The DGT's position remains stable regarding the application of special regimes and the validity of exchange operations or contributions. Clarifications have been added concerning the integration of income from income attribution entities for the calculation of ratios and the definition of an autonomous economic unit in the contribution of business lines.
