Swiss voters approved tax reform in a public vote on 19 May 2019, enabling the new legislation to become effective on 1 January 2020. The legal process to implement the new federal tax law into the cantonal tax laws has already been completed in five cantons (e.g. Basel-Stadt, Geneva, Glarus, Neuchâtel, and St.Gallen). The remaining cantons are expected to implement or, if a public vote is required, to vote about the implementation in the cantonal tax laws later this year.
