Umwandlungssteuergesetz

Umwandlungssteuergesetz (UmwStG) is a German federal law that regulates the tax treatment of corporate reorganizations. Its central aim is to enable tax-neutral restructuring by allowing certain transactions to occur without triggering immediate capital gains taxation for the involved entities and shareholders, provided specific conditions are met. The law applies to corporations and other tax subjects under German corporate income tax and interacts with the trade tax regime.

The scope covers common forms of corporate reorganization, including mergers (Verschmelzung), demergers (Spaltung), asset transfers to another entity, and transformations of legal form. Eligible reorganizations typically require continuity of economic substance and, in many cases, retention of ownership or business continuity. The UmwStG sets the conditions under which tax deferral may be granted, how assets and liabilities are valued for tax purposes, and how tax attributes such as loss carryforwards are treated in the reorganized structure.

Key features include deferral of capital gains recognition, continuation of existing tax bases, and rules governing the treatment of equity interests received in exchange or as consideration. The regime also covers administrative procedures, documentation requirements, and compliance rules to prevent abuse. It interacts with other major German tax statutes, notably the Körperschaftsteuergesetz (corporate income tax) and the Gewerbesteuer (trade tax), and is influenced by European Union guidelines on state aid and freedom of establishment.

History and status: the UmwStG was enacted to standardize and modernize the tax treatment of corporate reorganizations in Germany and has undergone revisions to reflect changing economic and legal contexts. See also: Verschmelzung, Spaltung, Umwandlung.
