With the adoption of the referendum on the Federal Law on Tax Reform and OASI Financing (STAF) of 19 May 2019, the tax-free repayment and use of reserves from capital contributions in the event of a direct partial liquidation of legal entities listed in Switzerland was restricted. The new provisions on the capital contribution principle in the DBG and the VStG come into force on 1 January 2020. Circular letter No. 29b also comes into force on 1 January 2020, replacing the previous circular letters No. 29 and 29a.
