How this directory is maintained

Untaxed currently covers tax years 2024–2026 and all 26 cantons, with municipality comparisons across more than 2,100 current municipalities. This directory follows the same published sources used by the app. “Last checked” records our latest review; a publisher may revise a source later. If a current-year cantonal source is not yet available, Untaxed may use the closest supported year and shows that fallback in the calculation result.
