Moving: what to do, and when
The date that decides a whole tax year
When you move to another canton, the canton you live in on 31 December taxes the entire year (Art. 68 para. 1 StHG). Moving in December rather than January therefore shifts a full year of tax to the new canton. For a move between municipalities inside one canton the rule is usually the same; cantonal law decides.
