The map in plain English

Pillar 2 is tied to your job. If you are employed and earn above the relevant thresholds, your employer pension fund is usually part of your compensation package.

Pillar 3a is private restricted retirement saving. You open it yourself with a bank, foundation, insurance company, or digital provider and may receive a tax deduction within the annual limit.

Vested benefits are what often happens when occupational pension money needs to be parked outside an active employer pension fund. This can happen after a job change, career break, or departure from Switzerland.

For many expats, the three accounts coexist naturally. A typical mobile professional might have an active Pillar 2 with their current Swiss employer, one or two Pillar 3a accounts with digital providers, and a vested-benefit account from a previous job waiting to be transferred or withdrawn. Each account runs on its own timeline, which is why labelling them correctly in your records matters from day one.

Why expats get confused

All three buckets can involve retirement money, Swiss tax, blocked access, and withdrawal rules. But they do not have the same source, provider type, contribution logic, or exit treatment.

A person may have Pillar 2 from employment, Pillar 3a from private contributions, and a vested-benefit account after leaving a job. The paperwork may arrive from different foundations, each with its own forms.

The practical step is to list each account separately. Do not call everything 'my Swiss pension'. Label the account type, provider, balance, investment allocation, and withdrawal conditions.

What to check before relocation

Before leaving Switzerland, make a pension inventory. Use the exit checklist to organize documents across accounts. Include employer pension certificates, 3a tax certificates, vested-benefit statements, and provider contact details.

Then ask which accounts can be withdrawn, which must remain, which can be transferred, and which tax authority will tax the payout. Pillar 2 and Pillar 3a can have different restrictions, especially around EU/EFTA moves.

A clean inventory is not exciting, but it prevents costly confusion during an already stressful relocation.

If you are not sure what an account is, ask the provider for the formal account type in writing. That is better than relying on app labels, because the legal category drives transfer options, withdrawal rules, and tax paperwork.

A useful inventory also records who controls each account after a job change. Employer pension funds, vested-benefit foundations, and 3a providers may all require different signatures, addresses, and tax certificates.

Contribution limits and contribution logic

Pillar 2 contributions are percentage-based, split between employer and employee, and tied to your insured salary. The deductibles and coordination amounts are set by the BVG law, and contribution rates vary by pension fund. Your employer deducts the employee share directly from your monthly salary.

Pillar 3a contributions are voluntary and capped annually by the Federal Council. For 2026, employees with a pension fund can contribute up to CHF 7'258. Self-employed persons without occupational coverage can contribute up to 20% of net earned income, capped at CHF 36'288. See the Pillar 3a maximum contribution 2026 guide for the latest thresholds and eligibility details.

Vested benefit accounts do not receive ongoing contributions. They hold occupational pension money that has left an active employer fund. No new money flows in unless it arrives from another pension fund or vested-benefit account. The balance grows only through investment returns within the account, and the interest rate or investment return depends on the foundation's policy.

This difference in contribution logic means a high earner with Pillar 2 coverage may still find Pillar 3a valuable—not because one replaces the other, but because each serves a different function. Pillar 2 is employment-linked and mandatory, while Pillar 3a is voluntary and portable from the moment you open it. Vested benefits sit between the two, acting as a parking facility for occupational pension capital in transition.
