After the German Bundestag (lower house of German legislature) has passed the 2020 Annual Tax Act (JStG 2020, in the version of the resolution recommendation of the Finance Committee of the German Bundestag) on 16 December 2020, the German Bundesrat (upper house of German legislature) also approved the bill in its last session of the year on 18 December 2020. The JStG 2020 considers amendments of various parts of German tax law: on the one hand these changes are to adapt to European law and to react to case law of the German Federal Fiscal Court, and on the other hand to implement fiscal policy decisions. In the following we highlight the main changes per area of tax law. With a few exceptions, the amendments apply from the date following the publication of the JStG 2020 in the Federal Law Gazette.
