Switzerland Tax Residence and Income

Residence creates broad liability

The FTA describes unlimited liability through personal tax residence. A stay can establish residence after at least 30 days with gainful work or 90 days without it, ignoring temporary interruptions. These are not substitutes for assessing domicile.

Swiss economic links can remain taxable

Without Swiss domicile or residence, Swiss business operations, a permanent establishment or real estate can still create limited tax liability. Non-residence is not a blanket exemption.

Income and wealth at different levels

Federal tax covers individual income, not individual wealth. Cantons and communes also levy income and wealth taxes. Wealth assessments generally use net assets, with deductions and thresholds varying by canton.

Cross-border allocation matters

Foreign property and business income require allocation rather than assuming every foreign receipt is exempt or fully taxable. Zurich's current guidance distinguishes personal and corporate cases and applies worldwide-income rate progression to individuals under the cited federal rules.

Individual-tax reform is a future change

The Federal Council announced in August 2026 that individual taxation will start in 2032. The announced reform must not be treated as a current replacement of household-assessment rules; canton-level implementation remains necessary.
