Hiring a foreign employee—whether a cross-border worker residing in neighboring France (G Permit) or an expatriate settling in the Lake Geneva region (B Permit)—involves strict compliance with the Swiss occupational pension system (LPP, or 2nd pillar). The principle of territoriality prevails: any employee subject to OASI (AVS) and employed in Switzerland must, under certain income and age conditions, be compulsorily affiliated, regardless of their passport or tax residence.
The Swiss labor market is deeply interconnected. In border cantons like Geneva, Vaud, Basel, or Neuchâtel, cross-border workers and expatriates make up an essential part of the workforce for SMEs and large companies alike. Given this volume of international talent, affiliation to the 2nd pillar (LPP) regularly raises complex questions for human resources departments and fiduciaries.
What are the employer's legal obligations during onboarding? Can a seconded European worker be exempted? How should the vested benefits of a cross-border worker permanently leaving Switzerland be managed? This practical 2026 guide decodes your obligations.
Before looking at the specific status of the foreign workforce, it is worth recalling the foundations of the Federal Law on Occupational Old-age, Survivors' and Invalidity Pension Provision (LPP). The affiliation of your employee, whether Swiss or foreign, becomes legal and mandatory as soon as three cumulative criteria are met:
The employer has a legal obligation to report any employee meeting these criteria to their pension fund from the first day of employment. An omission can result in the direct financial liability of the company in the event of a claim (disability/death).
With thousands of talents recruited every month in Greater Geneva, the Annecy basin, Thonon, the Ain region (Pays de Gex, Valserhône), or the Doubs region (Pontarlier, Morteau), managing G Permits is a daily task for HR departments in French-speaking Switzerland.
There is no distinction for cross-border workers: Swiss legislation applies by the principle of territoriality. A cross-border worker whose salary exceeds the threshold is compulsorily affiliated with your pension fund, regardless of whether they choose to be insured under the cross-border LAMal or CMU scheme (right of option).
HR departments are often highly solicited when a cross-border worker who decides never to work in Switzerland again is dismissed or resigns. It is crucial to inform them correctly about the destiny of their 2nd pillar to avoid post-contract disputes:
Beyond daily cross-border labor, Swiss companies massively recruit specialists internationally who physically settle in Switzerland.
If you recruit a developer, an engineer, or a senior executive in Europe and offer them a contract under Swiss law along with establishing their residence in Switzerland (obtaining a standard B Permit), they are treated exactly like a Swiss citizen. They are fully subject and contribute to the LPP.
One of the rare legal exceptions to LPP liability concerns "seconded" workers. These are employees sent by a foreign company to work temporarily in a branch or subsidiary based in Switzerland (intra-group employment contracts, or specific assignments).
Thanks to the Agreement on the Free Movement of Persons (AFMP), a worker seconded to Switzerland by an EU/EFTA company can remain insured exclusively in their home country's pension system for a maximum duration of 24 months (sometimes extendable up to 6 years depending on state exceptions). In this case, they are exempt from LPP affiliation.
The HR Obligation: To prove this exemption in the event of an audit, your company must mandatorily obtain Form A1, issued by the home country's social security fund, justifying that the seconded employee remains affiliated there.
Once the LPP affiliation obligations have been settled, the physical payment of the net salary poses a final technical and financial challenge for Swiss companies hiring numerous cross-border workers.
To retain a cross-border worker who lives and spends in euros (French mortgage, daily bills), more and more Swiss SMEs and fiduciaries propose paying the salary directly in euros, to guarantee them income stability against the foreign exchange market.
However, if the company's accounting and payslip (including AVS and LPP contributions) are established in CHF, paying its cross-border employee into their French (FR) IBAN via the traditional SWIFT banking system will generate massive costs for both parties:
