At its meeting on September 19, 2017, the Council of States discussed the interpellation "Corporate Tax Reform Zero".
Andrea Caroni's interpellation "Unternehmenssteuerreform Zero" (17.3426) requested that questions concerning the Corporate Tax Reform Zero, i.e. the general replacement of corporate taxes by a better tax system, be answered. The Federal Council's written reply partially satisfied the interpellation, which was settled with a brief discussion in the Council of States at its meeting on 19 September 2017.
