Tax notes

ESTV
  • The tax figures compare a concrete household scenario and do not replace an official individual calculation.
  • These figures are useful for comparison, but they still need confirmation in the official ESTV calculator before a final decision.
  • The exact address, deductions, and municipality assignment can materially change the final outcome.

Demographic notes

BFS
  • Population and age values come from BFS sources or postcode-level weighting.
  • Because the postcode mostly follows one municipality, demographic interpretation is cleaner here than on a split postcode.
  • For binding administrative or statistical figures, go back to BFS or municipal sources.
