What is the A1 certificate for Switzerland?
The A1 certificate for Switzerland confirms which social security law applies when posting staff between Germany (or the EU) and Switzerland. The legal basis is the Swiss–EU Free Movement Agreement, which extends EU Regulation (EC) 883/2004 to the bilateral relationship – Switzerland is neither an EU nor EEA member, but formally uses the same A1 form as EU states.
The key difference from a "normal" EU posting: Switzerland has its own, separate authorities. Employers posting a German employee to Switzerland apply for the A1 with the German statutory health insurer or the German Pension Insurance (DRV) as usual. Conversely, Swiss employers posting staff to the EU apply through the responsible Ausgleichskasse (compensation office) via the Swiss ALPS portal (Federal Social Insurance Office) – not via the German SV-Meldeportal.
Two directions: posting to and from Switzerland
Companies with staff in both countries benefit from keeping the two cases clearly separate:
| Direction | Responsible authority | Application portal | Legal basis |
|---|---|---|---|
| Germany → Switzerland (German employer posts staff) | German statutory health insurer / DRV Bund (privately insured) / GKV-Spitzenverband (DVKA) for multi-state activity | SV-Meldeportal (mandatory since 1 Jan 2025, electronic) | EU Reg. 883/2004 combined with the Swiss–EU Free Movement Agreement |
| Switzerland → Germany/EU (Swiss employer posts staff) | Responsible cantonal Ausgleichskasse | ALPS portal (Federal Social Insurance Office, BSV) | Swiss–EU Free Movement Agreement, Reg. 883/2004 / 987/2009 |
The A1 covers postings for up to 24 months; for habitual activity in multiple states (e.g. regular meetings, field work), a certificate can be issued for up to 5 years.
Personal scope: not every nationality qualifies
A frequently overlooked point: an A1 certificate for a posting to Switzerland can only be issued if the "personal scope" is met – meaning the posted person must hold EU, EEA or Swiss nationality.
Two real examples from German Pension Insurance practice where the application is rejected:
- A German-employed worker with Norwegian nationality is to be posted to Switzerland – rejected, because Norway as an EEA state falls under its own, narrower rule.
- An employee with Turkish nationality is to be posted to Switzerland for two months – rejected: "personal scope not met (nationality)".
For third-country nationals outside the EU/EEA/Switzerland, no A1 certificate is available under the Free Movement Agreement – other proofs or permits are required instead (see Swiss work permit).
Application, deadlines and short business trips
Since 1 January 2025, the A1 certificate must be applied for exclusively electronically in Germany – a paper application is no longer permitted. Applications run through payroll software or the fill-in aid on the SV-Meldeportal; multi-state activity or DVKA jurisdiction follow their own forms.
For short or one-off business trips (meetings, trade fairs, conferences), an exception applies: according to EAK Switzerland, for very short, one-off assignments abroad, applying in advance can be waived on proportionality grounds – the certificate can be requested retroactively if needed. For trips of up to seven days, Germany's Federal Ministry of Labour (BMAS) likewise confirms, citing ECJ case law, that a retroactive application is permitted.
Nonetheless: alongside France and Austria, Switzerland is one of the states with stricter enforcement. For business trips to these countries, both the DRV and EAK Switzerland explicitly recommend applying for the A1 certificate in advance rather than retroactively, to avoid delays or sanctions during checks.
FAQ
Does a German employee need an A1 certificate for a one-day business trip to Switzerland?
Formally yes, but for very short, one-off assignments (e.g. a meeting or trade fair), EAK Switzerland allows waiving the advance application on proportionality grounds; it can be submitted retroactively if needed. Since Switzerland enforces checks more strictly, applying in advance is still recommended.
Does a German A1 certificate automatically apply to Switzerland too?
Yes, provided the personal scope is met (EU, EEA or Swiss nationality) and the posting does not exceed 24 months. No A1 is possible for third-country nationals – other proofs are required.
Where does a Swiss company apply for an A1 certificate for an assignment in Germany?
Through the responsible cantonal Ausgleichskasse, preferably electronically via the Federal Social Insurance Office's (BSV) ALPS portal – not via the German SV-Meldeportal.
What happens if the A1 certificate is missing during a check in Switzerland?
Administrative sanctions may apply; EAK lists Switzerland among the states with strict enforcement. Proof of application (e.g. a previous A1 or a social security filing) may help in doubtful cases but does not replace a valid certificate.
Does an accompanying, non-working spouse also need a certificate?
No, but non-working spouses accompanying a person posted to Switzerland can voluntarily join the mandatory AHV (old-age insurance) within six months.
