Reading your numbers
Two documents tell you almost everything: your AHV statement (order it free from the compensation office – check for contribution gaps, each missing year cuts the pension) and your annual pension fund certificate showing projected retirement capital and conversion rate.
The gap most people find
High earners hit the AHV ceiling and coordinated pillar-2 deductions – replacement rates fall as income rises. That's exactly what pillar 3a (deductible up to CHF 7,258 in 2026 with a pension fund) is designed to patch.
Make retirement a line item
Treat 3a as a fixed monthly cost, not a year-end leftover.

The three pillars, and what each actually delivers
The first pillar (AHV/AVS) is the state pension. It is designed to cover basic subsistence, not your previous standard of living, and the amount depends on contribution years and average income. Full contribution years matter enormously: each missing year reduces the pension proportionally, and gaps are common among people who arrived in Switzerland mid-career.
The second pillar (pension fund / BVG) is occupational and employer-linked. It is mandatory above an income threshold, which means part-time workers and people with several small jobs may fall below it and accumulate far less than they assume. This is the single most under-recognised gap in Swiss retirement planning.
The third pillar (3a) is voluntary, tax-privileged private saving. For anyone with contribution gaps, an interrupted career or a part-time pattern, it is not a nice-to-have but the mechanism that compensates for the other two.
Estimating your own figure in five minutes
Start with the AHV: order a free statement of your individual account (Individuelles Konto) from your compensation office. It lists every contribution year on record – including the missing ones, which is the point of ordering it. Missing years from before you arrived are normal; missing years while you were resident here are worth investigating, because some can still be corrected.
Then read your pension fund certificate, which projects your capital and the resulting annual pension. Two numbers matter: the projected capital at 65 and the conversion rate used. Small changes in that rate move the resulting pension substantially.
Add your pillar 3a balances, then compare the total against your current fixed costs. The realistic outcome for many households is a noticeable gap between the first two pillars and their pre-retirement spending – knowing the size of that gap ten or twenty years early is precisely what makes it solvable.
What expats specifically need to check
Contribution years abroad may count under bilateral social security agreements, but the rules differ by country and are not automatic – they need to be claimed, and documentation from previous employers becomes hard to obtain over time. Collecting it while you can is a small task that prevents a large problem.
On leaving Switzerland permanently, second-pillar mandatory portions generally cannot be paid out in cash to those moving within the EU/EFTA and are instead transferred to a vested benefits account; pillar 3a can usually be withdrawn, subject to withholding tax that varies by the canton of the foundation. Choosing that canton in advance is a legitimate and often overlooked optimisation.
One recurring mistake: leaving small vested benefits accounts behind and forgetting them across several moves. Keeping a single sheet listing every pension-related account – with institution, account number and contact – is the cheapest retirement planning you will ever do.
