Basis: unweighted average of all municipalities per canton; single person, aged 35, no children, no confession, no wealth; 3-room flat; adult basic insurance, CHF 2'500 deductible. Rent (FSO 2020) and premium (FOPH 2026) are cantonal values, identical for every municipality of the canton. Between the reference incomes 60'000/80'000/100'000/120'000 the curve is read linearly — the resulting break-even differs by at most CHF 2'000 from the directly computed one across the 26 canton capitals.

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 from Basel-Stadt to Zürich on 20 December rather than 5 January therefore shifts a full year of tax — at a gross salary of CHF 80,000, about CHF 1'929.
Checklist and deadlines
- Deregistering and registeringusually 14 days
Deregister at the old municipality, register at the new one — with your certificate of origin and the tenancy agreement. The municipality sets the deadline; 14 days is common, some require 8.
- Health insuranceimmediately
Report the address: the basic-insurance premium depends on where you live, and it almost always changes when you change canton.
- Vehicle and driving licenceusually 14 days
Change of address at the road traffic office. Changing canton also means new number plates and a new vehicle registration document.
- Give notice on the flatusually 3 months
The local notice period, to the next local moving date. It is in the tenancy agreement — and the later you look, the more the double rent costs.
- Mail forwarding orderbefore the move
Covers the time it takes authorities, insurers and your employer to record the new address.
- Tax returnthe following year
After a change of canton it comes from the new canton — for the whole year, including the months spent in the old one.

Work out taxes, rent and health insurance for the destination before the moving date is fixed.
