However, the same rules do not apply to foreign non-profit entities that derive comparable income from Spain, but which are established in another EU/European Economic Area state without a branch in Spain. These entities cannot benefit from such tax exemptions and their financial contributors from Spain are also denied access to similar tax incentives. The Commission considers this to be discriminatory and a restriction of the free movement of capital as interpreted by the Court of Justice (cases "Centro di Musicologia Walter Stauffer" C-386/04 and Persche - C-318/07). A Spanish individual making a financial gift to a comparable foundation established in another Member State should be allowed to deduct the same amount from his tax base as if the same gift had been made to a Spanish foundation. A foreign foundation deriving income, e.g. rent, from Spain should be exempt from taxation on that income, in the same way that a Spanish foundation would be. The Commission has, therefore, asked Spain to amend its rules to bring them into line with EU law. The request takes the form of a reasoned opinion. In the absence of a satisfactory response within two months, the Commission may refer Spain to the Court of Justice of the EU.
