Note to HR Managers, Fiduciaries, and Executives
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.
1. The Basics of Mandatory LPP Affiliation in Switzerland
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:
- OASI (AVS) Liability: The employee must already be subject to the Old-Age and Survivors' Insurance (1st pillar), which is automatically the case when signing a local Swiss employment contract.
- The Relevant Salary (Entry Threshold): For the year 2026, the employee must earn an annual gross salary of at least 22,050 CHF (if the contract is for less than a year, this amount is prorated).
- Age Conditions: From January 1st following their 17th birthday, the worker is covered by the LPP for death and disability risks. From January 1st following their 24th birthday, they must begin contributing to retirement savings (old-age component).
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).
2. The Specific Case of Cross-Border Workers (G Permit)
With thousands of talents recruited every month in Greater Geneva, the Annecy basin, Thonon, the Ain region (Pays de Gex, ValserhĂ´ne), or the Doubs region (Pontarlier, Morteau), managing G Permits is a daily task for HR departments in French-speaking Switzerland.
Cross-border workers are 100% subject to the LPP
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).
Employer's Obligation During Onboarding:
When a cross-border worker is hired, the employer (or the fiduciary responsible for personnel administration) must mandatorily request a statement of their vested benefits. If they have previously worked in Switzerland, they have funds in their former employer's fund, or on a vested benefits account, which must be transferred to your company's fund.
Leaving Switzerland: Informing the Cross-Border Worker
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:
- Withdrawal of the mandatory part is impossible: As Switzerland has signed bilateral agreements with the EU/EFTA, a cross-border worker returning to work in France remains compulsorily subject to state social insurance. Therefore, they cannot request the cash withdrawal of the "mandatory LPP" part of their assets, unless they use these funds to purchase their main residence in France.
- Freezing of assets: Your former employee's mandatory funds will be transferred to a "Vested Benefits Account" opened in their name in a Swiss bank, where they will grow until retirement age (65).
- The extra-mandatory part: Only the so-called excess (extra-mandatory) part of the accumulated savings can, if applicable, be paid to them in cash into a bank account if they permanently leave Switzerland.
