On 22 September 2026 the Federal Compensation Office (Eidgenössische Ausgleichskasse, EAK) quietly released a 22-page guidance note entitled “Grenzüberschreitende Telearbeit, Workation”. The document is the first comprehensive federal interpretation of how Switzerland will apply EU social-security coordination rules and the July 2023 multilateral telework framework to Swiss-based staff who work temporarily from another country. The handbook confirms that Swiss employees may work up to 49.9 % of their time from their EU/EFTA/UK country of residence without triggering a switch of social-insurance legislation, provided both the home state and Switzerland have signed the framework agreement. Employers must file the case through the ALPS (Applicable Legislation Portal Switzerland) platform to obtain an A1 certificate or Certificate of Coverage. Above the 50 % threshold, or in non-signatory countries, the ordinary “place-of-work” principle applies and Swiss coverage ends unless a formal posting or voluntary continued insurance is approved. For non-EU treaty states such as the United States or India, the EAK reiterates that only a time-limited posting (up to 24 months) or a five-year insurance continuation is possible, and it explicitly excludes leisure-driven workations from the definition of “compelling personal reasons”. The note also reminds HR departments that visa, labour-law and tax obligations in the host country remain their responsibility even when Swiss social insurance continues. The clarification comes as Swiss multinationals scramble to finalise 2027 remote-work policies before annual budget cycles close. Legal advisers say the ALPS requirement will add administrative overhead but finally gives companies legal certainty after three years of provisional practices. Global mobility managers should review existing remote-work agreements, update employee communications, and ensure payroll systems can cope with split-tax and split-social-security scenarios. Failing to register could expose both company and employee to retroactive foreign social-security charges and fines. Smaller exporters who frequently send engineers abroad for ad-hoc telework assignments are advised to build an internal pre-trip approval process that checks ALPS eligibility, A1 timelines and export-control implications. The EAK announcement also signals that cantonal authorities will step up audits in 2027 as part of Switzerland’s commitment to EU free-movement enforcement.
