Tax joined
Wacker Vienna in 1927, and spent three and a half seasons there, before joining
First Vienna halfway through the
1930–31 season. In the summer of 1931, he joined former teammate
Karl Rappan at
Servette, where Rappan was the
player-manager. He helped Servette win two
Swiss Nationalliga titles, and finish runners-up in the
1933–34 Swiss Cup. Tax joined
Saint-Étienne for a transfer fee 50,000
francs. While at Saint-Étienne, he would form a duo with former Yugoslav international
Ivan Bek. In 1943, Tax was appointed as the manager of Saint-Étienne. Around the same time, Saint-Étienne president registered four players, including Tax, as employees of his company to circumvent
Vichy France's ban on both professionalism and foreign players. Because of this, they were banned by the
French Football Federation, but were pardoned following the
liberation of France. In July 1950, after Guichard return to the club as president following the ban, Tax was dismissed and replaced by former teammate
Jean Snella. ==Legacy==
