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.

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.
