Total income tax (federal, cantonal, municipal and personal tax) for a single person without children, no church affiliation, on CHF 100'000 gross employment income, tax year 2026. Because the same household is computed everywhere, the franc amounts are comparable across Switzerland — the tax multiplier is not.

The solar figure sums the BFE modelled roof potential of the 196 municipalities with a model — what roofs could generate, not what is installed.
