The German Investment Tax Reform will enter into force on 1 January 2018. Meanwhile, the German Fiscal Authorities are working on a comprehensive circular to address and clarify important questions arising in connection with the interpretation of the new law before the end of the year. In advance of this circular, the German Federal Ministry of Finance issued a letter to the relevant fund industry associations in which the Ministry explains its view of the determination of the partial tax exemption regime applicable to real estate funds, equity funds and mixed funds.
