What AHV actually is

AHV stands for Alters- und Hinterlassenenversicherung, which translates as old-age and survivors insurance. It is Switzerland's first pillar of retirement provision and functions as a pay-as-you-go state pension. Current workers fund current retirees. Your contributions build an entitlement to future pension income, calculated based on how many years you contributed and your average insured earnings across those years.

The 2026 maximum AHV pension is CHF 2,450 per month for a single person. A couple where both partners have full contribution records can receive up to CHF 3,675 per month combined. These amounts are not large relative to Swiss living costs, which is exactly why Pillars 2 and 3 exist.

How contribution years are counted

AHV contributions are mandatory for everyone living or working in Switzerland from age 21 onward. The full pension requires 44 contribution years for men and 43 for women. Each missing year reduces your eventual pension by approximately 1/44th of the maximum, roughly CHF 55 to CHF 60 per month, permanently.

For immigrants this is straightforward and uncomfortable arithmetic. Arrive at 30 and you already have a nine-year gap. Arrive at 40 and you have a nineteen-year gap. The gap is structural, not a mistake, and it cannot be closed simply by contributing more after you arrive.

Bilateral agreements and how they help

Switzerland has bilateral social security agreements with most European countries and a number of others beyond Europe. These agreements do not allow foreign pension contributions to fill your Swiss AHV record directly. What they do is ensure that years worked in an agreement country are considered when calculating your entitlement in Switzerland. The practical effect varies significantly by country and by your specific work history.

What immigrants should actually do about Pillar 1

The honest answer is that for most immigrants arriving after age 25, the AHV gap is largely unfillable. The strategy is therefore compensatory rather than corrective. Maximise Pillar 3a contributions every year. Investigate your Pillar 2 buy-in capacity, which can be very large for mid-career arrivals and is fully tax-deductible. Build supplementary private wealth that does not depend on state pension entitlement.

The worst approach is to simply not think about it. The gap compounds silently across your working years and becomes most visible and least correctable at retirement.
