Tax notes

ESTV
  • The tax figures compare a concrete household scenario and do not replace an official individual calculation.
  • For this postcode, the comparison can rely on a canton-median estimate. The ESTV calculator remains mandatory for the final number.
  • The exact address, deductions, and municipality assignment can materially change the final outcome.

Demographic notes

BFS
