Swiss tax returns for expats, handled in English

If your gross salary is CHF 120,000 or more a year, yes: you are automatically moved to a full tax return (subsequent ordinary taxation, TOU). Below that amount, filing is optional, but it often pays off if you pay into pillar 3a, buy back pension (LPP) years, pay childcare or have high professional costs. The request must reach the tax office by 31 March of the following year, and the choice cannot be undone. Our free TOU check tells you in 2 minutes whether it is worth it.

Yes. Once you file a full Swiss return, you declare your worldwide income and assets. Foreign real estate is not taxed in Switzerland, but it is taken into account to set your tax rate. Foreign accounts are also covered by the automatic exchange of information between tax authorities, so leaving them out is a real risk.

The main levers are pillar 3a contributions (up to CHF 7,258 in 2026 for employees with a pension fund), voluntary pension fund (LPP) buy-backs, and professional, childcare and mortgage interest deductions. LPP buy-backs can save a lot in high-income years, but the timing matters: a capital withdrawal within three years cancels the deduction.
