The Swiss pension system explained for expats

Pillar 1 is the AHV (OASI in English), a pay-as-you-go state pension financed by today's workers for today's pensioners. Pillar 2 is the occupational pension under the BVG, a funded scheme where your own capital is saved in your employer's pension fund. Pillar 3 is private and voluntary, with pillar 3a - the tax-privileged form - doing most of the work.

The design intent is simple: pillars 1 and 2 together are meant to replace roughly 60% of your final salary, and pillar 3 is expected to close the rest of the gap (BSV). For expats with a shortened Swiss career, that first assumption rarely holds, which is why the third pillar matters more here than the official brochures suggest.

Contribution years run from the year you turn 21 to the reference age of 65, giving a full career of 44 years. With all 44 years the monthly pension is at least CHF 1,260. The maximum of CHF 2,520 a month requires both a complete contribution record and an average annual income of at least CHF 90,720 across your career (AHV/IV, 2026 figures).

Married couples are treated as a unit and capped at 150% of the maximum, so a couple who both had strong careers receive at most CHF 3,780 a month combined rather than two full pensions. This so-called plafonnement surprises many double-income expat couples and is one reason pillars 2 and 3a carry more weight for them.

The headline change for 2026 is the 13th AHV pension. Approved by voters in March 2024, it is paid once a year from 2026, with the first payout in December 2026, and is worth roughly 8.3% extra on the annual amount. Separately, the AHV 21 reform has aligned the reference age at 65 for men and women, with women's age rising in steps between 2025 and 2028 for those born 1961 to 1964.

The arithmetic is unforgiving but transparent. Each year counts as roughly 1/44 of a full entitlement, so ten Swiss contribution years produce about 10/44, roughly 23%, of the pension your income level would have justified over a full career (indicative). You need at least one full contribution year to qualify for any Swiss pension at all.

Switzerland coordinates its social insurance with the EU/EFTA and has bilateral agreements with around 30 further countries. Under these, each country pays its own pro-rata pension for its own years, and Swiss pensions are paid abroad to nationals of agreement countries (ch.ch). Nationals of non-agreement countries who leave Switzerland permanently can instead apply for an interest-free refund of their AHV contributions- a return of the money, not a pension.

Gaps in your record can be repaired, but only within a five-year window. That is why the individual account extract is the single most useful document in Swiss retirement planning: a missed year discovered at 62 is permanent, one discovered at 34 is usually fixable.

Compulsory BVG cover starts once your annual salary exceeds CHF 22,680. From that salary the coordination deduction of CHF 26,460 is subtracted to give the insured, or coordinated, salary, and the mandatory scheme covers this up to a salary of CHF 90,720 (BVG key figures, 2026). Many employers insure more than the legal minimum in a super-obligatory portion with its own, usually lower, conversion rate.

Your capital grows through age-related savings credits on the coordinated salary: 7% from 25-34, 10% from 35-44, 15% from 45-54 and 18% from 55-65. Mandatory assets earn a guaranteed minimum interest rate of 1.25%, left unchanged for 2026 by the Federal Council. At retirement the mandatory capital converts at the minimum conversion rate of 6.8%, so CHF 100,000 of capital becomes CHF 6,800 of annual pension for life. Our second pillar guide unpacks how funds differ in practice.

Two levers matter for expats. Voluntary buy-ins (Einkauf) into your pension fund are deductible from taxable income and are one of the most effective Swiss tax tools for high earners - see tax optimisation. And when you change employer or leave the country, the capital moves to a vested benefits account. The mandatory portion can generally only be paid out in cash if you leave for a non-EU/EFTA country; move within the EU/EFTA and it stays locked until retirement age.

If you are affiliated to a pension fund, the 2026 maximum is CHF 7,258. Self-employed people without a pension fund may contribute 20% of net earned income up to CHF 36,288 (BSV, 2026). The full amount is deductible from taxable income in the year of payment, which at a typical marginal rate turns a maximum contribution into several thousand francs of tax saved.

From 2026 it also becomes possible to make retroactive buy-ins for missed years, counting from 2025 onwards and subject to conditions (indicative - watch the final implementing rules). For expats who arrive mid-career this is genuinely useful: a year missed while you were still settling in no longer has to be lost permanently.

Because pillar 3a is both an investment account and a tax instrument, how it is invested matters as much as whether it is funded. Our pillar 3a guide covers securities solutions, staggered accounts to spread the withdrawal tax, and what happens to the money if you leave Switzerland.

The BVG occupational pension reform was rejected in September 2024 with roughly 67% No. It would have cut the minimum conversion rate and reworked the coordination deduction. Because it failed, the 6.8% conversion rate and the current parameters remain in force - good news for anyone retiring soon, and a continuing structural strain for pension funds converting capital at a rate their returns do not fully support.

The 13th AHV pension, approved in March 2024, starts paying in 2026, but how to finance it is still being debated in parliament, with VAT increases and payroll contributions both on the table. Meanwhile AHV 21 continues its phase-in of the reference age of 65 for women through 2028.

For planning purposes: treat the 2026 figures as reliable, treat conversion rates and contribution levels a decade out as uncertain, and build your own third pillar rather than relying on political outcomes.

• Order your AHV individual account extract. It is free from your compensation office and shows every recorded contribution year. Check it for gaps while the five-year back-payment window is still open.
• Fund pillar 3a to the maximum every year. CHF 7,258 in 2026, invested rather than left in cash, and ideally split across staggered accounts.
• Consider a pension fund buy-in. Your fund's statement shows your buy-in potential. Spread buy-ins over several years to maximise the deduction, and respect the three-year lock before any capital withdrawal.
• Map your pro-rata entitlements across countries. Swiss years, home country years and any third country each pay separately. Work out the combined picture before assuming a shortfall - or a sufficiency. Start with the finances checklist.
