The participation of a limited liability company (GmbH) as general partner in a limited (non-trading) real estate managing partnership (KG) does not entitle the GmbH to an extended deduction of the part of income from the administration and use of own real estate within the meaning of Sec. 9 No. 1 2nd Sentence Trade Tax Act if the GmbH does not have a share in the assets of the KG. The Supreme Tax Court held that the general partner GmbH uses and manages third-party property rather than managing own real estate as presupposed by the statutes.
