Quotités of the canton and 50 communes
Jura first calculates a simple tax. The canton and the communes then apply their quotité to it: in tax year 2025, the canton levies 2.85 times this amount, the communes between 1.30 times (Les Breuleux) and 2.35 times (including Fontenais); Delémont is at 1.90, Porrentruy at 2.05.
On top of this comes church tax (impôt ecclésiastique) as a percentage of the cantonal tax – depending on the parish. What counts for your tax return is the commune of residence at the end of the year; the canton has 50 communes in the three districts of Delémont, Porrentruy and Franches-Montagnes.
