The Swiss three-pillar pension system: a practical guide for expats
Published on 2026-08-27
If you moved to Switzerland mid-career, you have probably received a pension fund certificate you never fully read, seen deductions on your payslip you cannot explain, and been told at some point that you should "do a 3a". Nobody sat you down and explained how the pieces fit together.
This guide does that. It covers what each pillar actually does, what the numbers are in 2026, and the three points where expats most often lose money without realising it.
One thing to know upfront: the Swiss system was designed around a person who works in Switzerland from their early twenties until retirement. If you arrived at 30, 35 or 40, you are not that person, and some of the standard advice does not apply to you. Where that matters, I say so.
The system at a glance
Switzerland organises retirement provision into three pillars. Each has a different purpose, a different owner, and different rules.
What it is | Who pays | What it is meant to cover | |
|---|---|---|---|
Pillar 1 — AHV/AVS | State pension, mandatory | You and your employer, split equally | Basic subsistence |
Pillar 2 — BVG/LPP | Occupational pension via your employer, mandatory above a salary threshold | You and your employer (employer pays at least half) | Maintaining your accustomed standard of living |
Pillar 3 — Pillar 3a and 3b | Private savings, voluntary | You | Closing the gap between the first two pillars and what you actually need |
Pillars 1 and 2 together are designed to replace roughly 60% of your final salary. In practice, many people land well below that. For expats with an interrupted Swiss contribution record, the shortfall is usually larger.
Pillar 1: AHV, the state pension
AHV (Alters- und Hinterlassenenversicherung, AVS in French) is mandatory for everyone living or working in Switzerland. The contribution rate in 2026 is 8.7% of your salary, split equally between you and your employer, so 4.35% each. There is no upper salary ceiling on contributions, but there is a ceiling on benefits.
What you get
A full AHV pension in 2026 pays between CHF 1,260 and CHF 2,520 per month for a single person. Married couples are capped at a combined CHF 3,780.
To receive the maximum, you need two things at the same time:
44 contribution years, counted from 1 January of the year you turn 21 until you reach reference age, with no gaps
An average annual income of at least CHF 90,720 across those years, adjusted for inflation
Reference age is 65 for men. For women born between 1961 and 1969 it is rising in stages: a woman born in 1962 reaches reference age in 2026 at 64 years and 6 months. From 2028 it is 65 for everyone.
New in 2026: a 13th AHV payment will be made for the first time in December, worth an extra 8.33% of the annual pension. It applies to retirement pensions only, and it is paid automatically.
The point that matters most for expats
Every missing contribution year reduces your AHV pension by 1/44, which is roughly 2.3%, permanently.
Run the numbers on a typical expat career. If you arrived in Switzerland at 35 and work here until 65, you accumulate 30 contribution years instead of 44. That is 14 missing years, a reduction of about 32%. Even on a high salary throughout, your maximum realistic AHV pension is around CHF 1,718 per month rather than CHF 2,520.
This is not a mistake or something that can be appealed. It is how the system works. But it has two practical consequences:
Order your individual account statement (IK-Auszug). It is free from your compensation office (Ausgleichskasse) and shows exactly which years are recorded. People find genuine errors: an employer that never registered them, a year recorded under a misspelled name, a gap from a period they thought was covered.
Gaps from the last five years can still be paid retroactively. Older gaps cannot. If you had a year without contributions recently, for example between jobs or during an unpaid break, check it now rather than at 64.
If you worked in an EU or EFTA country before moving here, those years are not lost, but they do not increase your Swiss pension either. Under the bilateral agreements, each country pays its own pro-rata pension based on the periods completed there. You end up with several smaller pensions from several countries rather than one larger Swiss one. Keep the records from every country you have worked in.
Pillar 2: the occupational pension
Your pension fund (Pensionskasse, BVG or LPP) is tied to your employer. This is usually the largest single retirement asset an expat in Switzerland builds up, and it is the one most people understand least.
Who is covered
You are compulsorily insured if you earn more than CHF 22,680 per year with one employer, on a contract lasting more than three months. Below that threshold, you are not covered by the mandatory scheme.
Savings contributions start on 1 January after your 24th birthday. Risk cover for death and disability starts earlier, on 1 January after your 17th birthday.
How your insured salary is calculated
Not all of your salary is insured. A fixed amount, the coordination deduction (Koordinationsabzug), is subtracted first. In 2026 it is CHF 26,460.
So on a salary of CHF 90,000, your coordinated salary is CHF 90,000 − CHF 26,460 = CHF 63,540. Contributions and future benefits are calculated on that figure, not on your gross salary.
The other 2026 reference figures:
Upper salary limit for the mandatory scheme: CHF 90,720
Maximum coordinated salary: CHF 64,260
Minimum coordinated salary: CHF 3,780
Minimum interest rate on mandatory savings: 1.25%
Conversion rate at reference age: 6.80%
Salary above CHF 90,720 is not covered by the mandatory scheme, but most employers insure it voluntarily in what is called the extra-mandatory portion (Überobligatorium). The distinction between mandatory and extra-mandatory looks technical, but it becomes very important if you ever leave Switzerland. More on that below.
A reform that would have replaced the fixed coordination deduction with a percentage-based one was rejected by voters in September 2024. The fixed deduction therefore remains in place. This penalises part-time employees in particular, because the full deduction applies regardless of your workload.
What to check in your situation
Read your pension fund certificate once a year. It shows your accumulated capital, your insured salary, and your projected pension. If your salary rose and your insured salary did not, ask why.
Compare schemes when you change jobs. Pension fund terms vary enormously between employers and are rarely part of salary negotiations, even though the difference over ten years can exceed a salary increase.
If you work part-time or hold two jobs, check whether you are insured at all. Two positions of CHF 20,000 each leave you below the threshold in both, and therefore uninsured in the mandatory scheme, unless your funds allow voluntary insurance.
Voluntary buy-ins (Einkauf) are deductible from taxable income. If your certificate shows a buy-in potential, this is one of the most effective tax planning instruments available in Switzerland. It needs to be planned around your withdrawal timeline, not done at random.
Pillar 3a: private provision, and where expats lose money
Pillar 3a is voluntary, tax-privileged retirement saving. Anyone with income subject to AHV contributions in Switzerland can pay in, regardless of nationality or permit type.
The 2026 maximum amounts
CHF 7,258 if you are a member of a pension fund
20% of net earned income, up to CHF 36,288, if you are not, for example if you are self-employed or earn below the BVG entry threshold
Contributions must reach the account by 31 December to count for that tax year.
The mistake that costs expats the most
Pillar 3a contributions are deductible from taxable income. But if you are taxed at source (Quellensteuer), which applies to most foreign employees without a C permit, the deduction is not applied automatically. Your employer deducts tax from your salary using a standard tariff that does not know about your 3a payment.
To claim it, you have to request a subsequent ordinary assessment (Nachträgliche ordentliche Veranlagung, NOV):
If your gross income exceeds CHF 120,000, this happens automatically
Below that, you must apply, and the deadline is 31 March of the following year. This deadline cannot be extended.
Two things to understand before you apply. First, once you have submitted the request, it cannot be withdrawn, and it applies to all subsequent years until your withholding tax liability ends. Second, switching to ordinary assessment brings your worldwide assets into scope for wealth tax, and you will file a tax return every year from then on.
Whether it is worth it depends on how your deductible costs compare to the flat-rate allowances already built into the withholding tax tariff. For someone paying the full 3a amount, it usually is. It is worth calculating rather than assuming.
New in 2026: closing past gaps
Since 1 January 2026, it has been possible for the first time to make retroactive Pillar 3a contributions for years in which you did not pay the maximum. The conditions are strict:
Only gaps from 2025 onwards qualify. Anything earlier is permanently closed.
You can go back a maximum of ten years.
You need income subject to AHV contributions both in the gap year and in the year you make the payment.
You must have paid the full current-year maximum first.
Each gap year can be closed with one single payment, and the total retroactive amount in a year cannot exceed the current maximum.
You must apply to your 3a provider before paying.
It is no longer possible once you have started drawing 3a benefits.
Note the condition on AHV-liable income. A year you spent abroad without Swiss earnings does not qualify, even if it falls within the ten-year window. For internationally mobile professionals, that limits how useful this rule is, which is exactly why it is worth checking your specific record rather than assuming either way.
What happens to your pension if you leave Switzerland
Most expats leave eventually. The rules differ sharply by pillar and by destination, and decisions made in the last few weeks before departure are usually the expensive ones.
Pillar 1: AHV
AHV contributions generally cannot be paid out as a lump sum when you leave. If you move to an EU or EFTA country, your entitlement is preserved and paid as a pension when you reach reference age, wherever you live at that point. It is deferred, not lost.
For nationals of countries with no social security agreement with Switzerland, a refund of contributions may be possible. This depends on your nationality and the specific agreement, and should be clarified individually before you leave.
Pillar 2: your pension fund
This is where the mandatory and extra-mandatory distinction becomes financially significant.
Moving to an EU or EFTA country and remaining subject to compulsory pension insurance there: only the extra-mandatory portion can be paid out in cash. The mandatory portion must stay in Switzerland in a vested benefits account (Freizügigkeitskonto) until you approach retirement age.
Moving to a country outside the EU/EFTA: a full cash payout of both portions is generally possible. This includes the United States, the United Kingdom since Brexit, Singapore, Canada, Australia and the UAE, among others.
Two details that catch people out: Liechtenstein has the same occupational pension rules as Switzerland and does not count as a foreign country here. And cross-border commuters who continue working in Switzerland are not considered to have left, so they cannot withdraw.
Pillar 3a
On permanent departure from Switzerland, Pillar 3a can generally be withdrawn.
Tax on the way out
Lump-sum withdrawals from Pillars 2 and 3a are taxed separately from your other income, at a reduced rate. If you are no longer resident, the tax is levied at the location of the foundation holding the assets, and rates vary considerably between cantons. Your new country of residence may tax the payment as well, depending on the applicable double taxation agreement.
Because the rate is progressive, splitting a large withdrawal across two tax years often reduces the total substantially. This only works if it is planned before you leave, not after.
A practical checklist
Whatever stage you are at, these are worth doing:
Order your IK statement from your compensation office and check it for gaps and errors.
Read your pension fund certificate and note your insured salary, accumulated capital, and buy-in potential.
If you are taxed at source and pay into Pillar 3a, calculate whether an NOV request is worth it, and note the 31 March deadline.
Check whether you have Pillar 3a gaps from 2025 onwards and whether you meet the conditions to close them.
Keep social insurance records from every country you have worked in, including old payslips and contribution statements.
If you are thinking about leaving Switzerland, get advice at least a year in advance, not in your final month.
Frequently asked questions
Can I pay into Pillar 3a as a foreigner without a C permit? Yes. Anyone with income subject to Swiss AHV contributions can pay in, regardless of permit type. The difference is how you claim the tax deduction: if you are taxed at source, you need to request a subsequent ordinary assessment.
How much AHV pension will I get if I only worked in Switzerland for 20 years? Roughly 20/44 of a full pension, so about 45%, adjusted for your average income. The exact figure depends on your recorded earnings. Your IK statement is the starting point for a precise calculation.
Do my working years in another country count towards my Swiss pension? Not towards the Swiss amount. Under the bilateral agreements with the EU and EFTA, periods completed abroad count towards your eligibility, but each country pays its own pro-rata pension. You receive several separate pensions rather than one larger one.
Can I take my pension fund money with me when I leave Switzerland? It depends on your destination. Outside the EU/EFTA, generally yes, in full. Within the EU/EFTA, only the extra-mandatory portion if you remain subject to compulsory insurance there. The mandatory portion stays in a Swiss vested benefits account.
Is it better to pay into Pillar 3a or make a pension fund buy-in? Both reduce taxable income. Which is more effective depends on your marginal tax rate, your buy-in potential, your planned withdrawal timing, and how long you expect to stay in Switzerland. If you may leave within a few years, the answer often differs from the standard advice given to Swiss residents.
What is the coordination deduction and why does it reduce my pension? It is a fixed amount, CHF 26,460 in 2026, subtracted from your salary before your occupational pension is calculated. Its purpose is to avoid insuring the portion of income already covered by AHV. It affects part-time employees disproportionately, because the full amount is deducted regardless of workload.
Where to go from here
The three-pillar system is not complicated in principle. What makes it difficult for internationally mobile people is that the rules were written for an uninterrupted Swiss career, and yours is not one. The gaps, the withholding tax mechanics, and the departure rules are where the money actually sits.
