Der Solidaritätszuschlag ist verfassungsgemäß. Mit einem entsprechenden Urteil hat das Bundesverfassungsgericht eine Klage von sechs FDP-Politikern abgewiesen. Sie hatten argumentiert, der Zweck der Abgabe sei weggefallen.
The German Federal Constitutional Court rejected a lawsuit filed by FDP politicians against the "Solidaritätszuschlag" (Solidarity Surcharge). The court ruled that the surcharge, even in its reduced form since 2021, is constitutional, as the federal government still has additional financial needs due to German reunification. The court noted that such a supplementary tax cannot be levied indefinitely and could become unconstitutional if the additional financial need ceases to exist.
