Before moving abroad permanently, deregister with the municipality according to the cantonal procedure; after deregistration, Swiss citizens must generally register with the competent Swiss representation abroad within 90 days.

Municipality/canton of residence and, depending on status, tax/insurance bodies; for Swiss citizens abroad, subsequently the Swiss representation.

Identity, confirmation of deregistration and the new foreign address, where required.

Check health insurance, tax, vehicle, pension provision and residence status separately.

As a rule, the insurance obligation ends when you move away from Switzerland. Exceptions include certain pensioners, cross-border commuters and posted workers.

Contact your own health insurer first; for cross-border exceptions use the competent bodies identified by the Federal Office of Public Health.

Have proof of deregistration/new residence and evidence of employment, pension, posting or cross-border status ready where relevant.

A temporary stay abroad without moving your residence generally does not end the Swiss insurance obligation.

Unlimited tax liability generally ends when you move away from Switzerland. Special rules apply to a tax liability that ends during the tax year.

The tax administration of the canton you leave is particularly relevant; limited tax liability may remain if you continue to hold taxable assets in Switzerland.

Have the departure date, new address, and information on income, assets and any taxable values remaining in Switzerland ready.

Property or other economic connections in Switzerland can continue to create limited tax liability despite moving abroad.
