The eastern Swiss cantons of St. Gallen (SG), Thurgau (TG), Appenzell Ausserrhoden (AR) and Appenzell Innerrhoden (AI) have implemented a number of changes in the taxation of profits and capital as part of the STAF as of 1 January 2020.

Implementation of the STAF in the Canton of Zurich
Although the Canton of Zurich dealt with the implementation of the Federal Law on Tax Reform and OASI Financing ("STAF") at an early stage and issued various practice notes, various implementation issues still arose in the months following its entry into force.

Implementation of the STAF in the Canton of Ticino
On 1 January 2020, the Federal Act on Tax Reform and Financing of the OASI (STAF) (Riforma fiscale e finanziamento dell'AVS, RFFA) entered into force. Among other things, the federal law modified certain provisions of the Federal Direct Tax Act (DBG) and the Direct Tax Harmonisation Act (StHG). In doing so, the Confederation leaves the cantons some leeway in implementing the STAF in their own tax legislation. This article analyses the implementation of the STAF by the Canton of Ticino.
Implementation of the Federal Law on Tax Reform and OASI Financing (STAF) in the Canton of Berne
Based on the Corporate Tax Reform Act III (USR III) passed by the Federal Parliament on 17 June 2016, the Berne Cantonal Government Council expressed its views on the content of USR III at the end of November 2016, as well as the possible effects on the Canton of Berne and the preliminary positioning of the Canton of Berne in intercantonal tax competition. In the interests of Berne as a business location, the Government Council intended to cushion the abolition of cantonal tax privileges and the associated transition to ordinary taxation with replacement measures as part of the revision of the tax law in 2019. It was planned to reduce the maximum tax burden on profits from 21.64% in two steps; namely to 20.20% in 2019 and then to 18.71% in 2020. Further reductions in the profit tax rate should then have taken place with the 2021 tax law revision. In addition, the 2019 tax law revision also provided for the reduction of the applicable capital tax rate.
