On 16 June 2021, the Finance Directorate of the Canton of Zurich announced that the rates and deductions for income and wealth tax will not be adjusted for inflation, as this has been negative since 2012.
The national consumer price index is decisive in each case; only when the negative inflation has been made up for and is higher, will the next equalisation of the two-year tax base period take place.
