On 16 October 2015, the Bundesrat (German Federal Council) approved the 2015 Tax Amendment Act (Steueränderungsgesetz 2015), which includes the amendments previously proposed and approved by the Bundestag (German Parliament). This new Act amends, inter alia, the German Real Estate Transfer Tax Act and is based mainly on the German federal states' initiatives, which were not implemented as part of the tax amending acts in 2014. The following Newsletter will analyze these amendments to the German Real Estate Transfer Tax Act, which include an adjustment in computational basis for the substitute assessment basis (Ersatzbemessungsgrundlage) for the purpose of the real estate transfer tax as well as the clarification of when the transfer of an indirect interest holder in a real estate holding partnership would result in a taxable event.
