What is it?

Understand your rights according to your status

OASI, occupational pension, pillar 3a, vested benefits and leaving Switzerland: the rules change depending on whether you are a resident, cross-border worker or in transition.

Mandatory?

OASI and occupational pension according to activity

If you work in Switzerland, you in principle contribute to OASI. Occupational pension applies from CHF 22,680 of annual salary in 2026.

Key point

Anticipate before departure

Not everything can be withdrawn automatically. Destination EU/EFTA or outside the EU, mandatory or supplementary part: the timing of the choice matters.

Cross-border / expat pension priorities

Coordinate Swiss rights with the country of residence.

  1. Top-up 3a / 3b By tax and project
  2. If employed in CH LPP Swiss 2nd pillar
  3. Base AHV / coordination Acquired rights and portability

Contributing without understanding future payouts is the classic trap.

The Swiss system in three pillars

Swiss pension provision is based on three levels: AVS/AI for vital needs, LPP to supplement retirement income, and private pension 3a/3b to fill the gaps and optimize taxation. Voir aussi comprendre les trois piliers.

For an expat or cross-border worker, the difficulty is not only understanding the pillars. You also need to know what happens if you leave Switzerland, work in several countries, change status or want to deduct a 3rd pillar.

Pillar
Role
Point of attention
1st pillar OASIState
Vital needs, international coordination of insurance periods.
No capital recoverable on exit; the pension is claimed later.
2nd pillar occupational pensionEmployer
Retirement, disability, death; vested benefits in case of change or departure.
EU/EFTA: mandatory part often blocked; outside EU: total withdrawal more frequent.
3rd pillar 3aPrivate
Tied savings, 2026 limit CHF 7,258 with occupational pension, or up to CHF 36,288 without occupational pension.
For a cross-border worker, the real tax deduction depends on status and subsequent ordinary taxation.

The logic for expats and cross-border workers

Clear status + Located assets + Verified taxation = Clear decision

The best solution is not always immediate withdrawal. It depends on the country of residence, family and timing of departure.

1st pillar: OASI and international coordination

If you work in Switzerland, you in principle contribute to OASI/DI. Swiss contribution years will count towards your future Swiss pension. In a career across several countries, coordination agreements generally allow insurance periods in each country to be taken into account, but each state calculates its share according to its rules.

OASI contributions are generally not recovered as capital on departure. The pension is claimed at the applicable retirement age, often via the organisation in the country of residence that coordinates with Switzerland.

2nd pillar: occupational pension and vested benefits

Employees in Switzerland are affiliated to occupational pension from CHF 22,680 of annual salary in 2026, according to age and employment conditions. For cross-border workers, occupational pension works as for resident employees if affiliation conditions are met.

In case of job change, the assets must be transferred to the new fund or a vested benefits institution. In case of departure to the EU/EFTA with local mandatory affiliation, the mandatory part remains in principle blocked in Switzerland; the supplementary part can be withdrawn. Outside the EU/EFTA, total withdrawal is often possible, subject to formalities and withholding tax.

Resident expat

Cross-border worker

Check occupational pension, 3a taxation, quasi-resident status and rights when Swiss activity stops before contributing or withdrawing.

Planned departure

Choose the vested benefits institution, simulate tax and distinguish mandatory / supplementary parts before administrative exit.

International family

Coordinate beneficiaries, succession, death insurance and taxation between countries to avoid protection gaps.

Pillar 3a: tax opportunity, but not automatic

Le pilier 3a est accessible aux personnes avec un revenu soumis à l’AVS. En 2026, le plafond est de CHF 7’258 pour les personnes affiliées à une caisse de pension, ou 20 % du revenu net jusqu’à CHF 36’288 pour les indépendants sans LPP.

For cross-border workers taxed at source, the 3a tax deduction depends in particular on quasi-resident status and subsequent ordinary taxation (TOU), according to the canton and household situation. A 3a contribution can be wise, but the real tax saving must be checked before committing.

Leaving Switzerland: anticipate before closing accounts

Leaving Switzerland does not mean automatically recovering all pension assets. The 2nd pillar follows different rules depending on destination and the mandatory or supplementary part. Pillar 3a can in principle be withdrawn in case of definitive departure, but conditions, deadlines, forms and taxes must be coordinated.

The canton of the vested benefits or pension foundation influences withholding tax on a capital withdrawal. Choosing the right institution before departure can therefore have a significant impact on the net amount received.

Common pitfalls

Mistakes are rarely paid when contributing. They appear on departure, when changing employer or at tax filing.

Everything withdrawable in the EUThe mandatory occupational pension part often remains blocked if you are insured in the EU/EFTA.
Forgotten vested benefitsWithout choosing an institution, assets can remain inactive or poorly located.
3a without deductionContributing without checking subsequent ordinary taxation or quasi-resident status.
Withdrawals in the same yearCombining 2nd pillar and 3a without simulating tax reduces the net amount.
