Living in Triesen (Liechtenstein) and working in Switzerland: taxed in your state of residence
Triesen is one of Liechtenstein's 11 municipalities: residents who work in Switzerland as genuine daily commuters are taxed exclusively in their state of residence (art. 15 para 4 CH-LI treaty), provided they don't exceed 45 non-return working days per year. Note: this corridor's dominant flow runs the other way — in 2023, 14'891 people commuted Switzerland → Liechtenstein versus 2'426 in this direction (~6.1:1 (CH->LI is the dominant direction)); this guide covers the minority flow, consistent with this site's audience.

No — and this matters: in 2023 the dominant flow was the opposite, Switzerland → Liechtenstein (14'891 people versus 2'426, a ratio of ~6.1:1 (CH->LI is the dominant direction)). This guide covers the minority flow because it matches this site’s audience, not because it is the corridor’s majority pattern.

FAQ
How is a Liechtenstein resident working in Switzerland taxed?
Under the CH-LI double-taxation treaty (SR 0.672.951.43, art. 15 para 4), genuine daily commuters are taxed exclusively in their state of residence — structurally different from the arrangements with Italy, France or Germany.
What happens if I do not return home every day?
The treaty’s protocol (point 4 lit. c) sets a 45-working-day/year non-return threshold beyond which frontaliere status is lost. The source consulted does not specify what changes fiscally after that status is lost — do not assume an analogy with Germany’s 60-day rule.
Do I need to clear customs every day to get to work?
No: Liechtenstein and Switzerland have formed a customs union since 1923 (SR 0.631.112.514), share a monetary treaty (1980/1981, SR 0.951.951.4) and the same VAT territory — no customs formalities, no currency change, no VAT-rate difference.
Where are AVS/AI (old-age and disability) social-security contributions paid?
The place-of-work principle applies (1989 bilateral agreement, art. 5, with exceptions under art. 6): contributions are normally paid where you work, i.e. in Switzerland.
Is the Liechtenstein → Switzerland flow the most common on this corridor?
No — and this matters: in 2023 the dominant flow was the opposite, Switzerland → Liechtenstein (14'891 people versus 2'426, a ratio of ~6.1:1 (CH->LI is the dominant direction)). This guide covers the minority flow because it matches this site’s audience, not because it is the corridor’s majority pattern.
