The Swiss three-pillar system
How Swiss retirement provision is built: the state AHV, the occupational pension, and private 3a saving — what each is for, who pays, and where the gap usually appears.
In one line: Three pillars, three different jobs, three different sets of rules — and knowing which one is supposed to do what is the foundation for everything else.
Swiss retirement provision is not one system but three, built at different times on different principles. This guide explains what each is for.
Pillar 1 — the AHV
Purpose: cover basic subsistence needs.
The AHV is compulsory for everyone who lives or works in Switzerland, and it is financed on a pay-as-you-go basis: today's contributions fund today's pensions. Nothing is saved in your name.
It is deliberately redistributive. The pension depends on your contribution years and your average income, but income only counts up to a ceiling, and the maximum pension is exactly twice the minimum. In 2026, with a complete 44-year record, that range is CHF 1'260 to CHF 2'520 per month, with two married pensions capped together at CHF 3'780. The reference age is 65, and from 2026 there is a 13th annual payment.
Pillar 2 — the occupational pension
Purpose: together with the AHV, allow you to continue your accustomed standard of living in an appropriate manner. That aim is written into the Federal Constitution.
Unlike the AHV, Pillar 2 is funded: contributions accumulate in an account in your name, with your employer paying at least half. It is compulsory for employees whose annual salary with one employer exceeds CHF 22'680.
The catch that surprises people is that you are not insured on your whole salary. The coordination deduction of CHF 26'460 comes off first, because the AHV is deemed to cover that portion. The remainder is your insured salary, and under the mandatory scheme it is capped, because salary only counts to CHF 90'720.
At retirement the balance is converted into a pension using the conversion rate, which is at least 6.8% on the mandatory portion.
Pillar 3 — private provision
Purpose: close whatever the first two leave open.
This pillar is voluntary. Pillar 3a is tax-privileged: contributions are deductible up to an annual limit — CHF 7'258 in 2026 for someone with a pension fund, or 20% of net income up to CHF 36'288 for a self-employed person without one. In exchange the capital is locked until close to retirement. Pillar 3b is ordinary saving with no limit, no lock and no deduction.
Where the gap actually appears
The structure works best for a long, unbroken, middle-income career with one employer. It works least well for:
- High earners, because both the AHV and the mandatory Pillar 2 stop counting salary above CHF 90'720;
- Part-time and multiple-job workers, because the entry threshold and the flat coordination deduction bite hardest at low individual salaries;
- Interrupted careers — years abroad, a late arrival in Switzerland, time out of the workforce — because AHV years are counted and Pillar 2 credits are not earned;
- The self-employed, who have no compulsory second pillar at all.
If you recognise yourself in that list, the third pillar and voluntary buy-ins are not optional extras. They are what closes a gap the first two pillars were never designed to close.
Common questions
What are the three pillars?
The state AHV (subsistence), the occupational pension (maintaining your standard of living), and private 3a/3b saving (voluntary top-up).
What is the difference between them?
The AHV is compulsory for everyone and pay-as-you-go. Pillar 2 is compulsory for employees above an income threshold and funded in your own name. Pillar 3 is voluntary, with 3a carrying a tax deduction and a lock-up.
Is the second pillar compulsory?
For employees, yes, once annual salary with one employer exceeds CHF 22'680. The self-employed may join voluntarily.
Do the first two pillars cover my current lifestyle?
They are intended to allow continuation of your accustomed standard of living in an appropriate manner, but the outcome depends on your income level, career continuity and canton. High earners and interrupted careers routinely fall short, which is what the third pillar exists for.
