Key takeaways
- The pillar 3a maximum for tax year 2025 is CHF 7,258 if you belong to a pension fund. If you do not, it is 20% of your earned income, up to CHF 36,288.
- The contribution comes straight off your taxable income. At a 30% marginal rate, a full contribution saves roughly CHF 2,177.
- Money must reach your 3a provider by 31 December. A transfer that arrives on 2 January counts for the next year.
- From 2026 you can pay into years you missed. Someone with a pension fund can then pay CHF 14,516 in one year: the ordinary CHF 7,258 plus a catch-up of up to CHF 7,258.
- If you are taxed at source, the deduction does not happen automatically. You have to claim it.
BVV 3 (the federal pillar 3a ordinance) sets these amounts in Art. 7 for federal, cantonal and communal tax alike, so the same maximums hold in all 26 cantons.
What pillar 3a is, and why it cuts your tax
Three pillars: the state pension (AHV/AVS), your occupational pension fund (PensionskassePensionskasseOccupational pension fund (pillar 2)FRcaisse de pension (institution de prévoyance)ITcassa pensioni (istituto di previdenza)The workplace pension scheme funded by you and your employer. Your contributions are already inside the net salary figure — do not deduct them again.Where you see itOn your salary certificate and in your annual pension statement.Open in the glossary →), and pillar 3a, which is voluntary, tied until retirement and tax-privileged.
Whatever you pay into 3a, up to the legal maximum, comes off that year's taxable income. At a 30% marginal rate a full 2025 contribution of CHF 7,258 cuts your bill by roughly CHF 2,177. What you save depends on your income, your municipality and your marital status.
Hold it as a bank account (3a-Konto) or an insurance policy. Both qualify, and you can hold more than one, which matters later for withdrawals.
What are the 2025 limits?
Which of the two maximums applies depends on one question: are you a member of an occupational pension fund (Pensionskasse)? Employment status is not the test, so an employee earning too little to be enrolled gets the larger limit too.
| Your situation | 2025 maximum | 2026 maximum | How it is calculated |
|---|---|---|---|
| Member of a pension fund (the usual case if you receive a salary certificate, LohnausweisLohnausweisSalary certificateFRcertificat de salaireITcertificato di salarioYour employer's annual statement of what it paid you and what it withheld. One per job, and the starting point of the whole return.Where you see itSent by your employer in January or February.Open in the glossary →) | CHF 7,258 | CHF 7,258 | A flat amount. All of it deductible. |
| No pension fund: self-employed, or an employee not enrolled | CHF 36,288 | CHF 36,288 | 20% of earned income (Erwerbseinkommen), capped at this figure |
| Catch-up for a missed year (new from 2026) | not available | up to CHF 7,258 on top of the ordinary contribution | Capped at the ordinary member limit for the year you pay in, and at the total you underpaid over the previous ten years |
The second figure is larger because without an occupational pension fund the third pillar has to cover more of your retirement. The 20% is calculated on earned income, and CHF 36,288 is the ceiling however high that income goes.
Several accounts share one maximum: CHF 5,000 into one and CHF 3,000 into another puts you over the CHF 7,258 member limit, and the excess is not deductible.
Each provider issues a contribution certificate (BescheinigungBescheinigungContribution certificateFRattestationITattestazioneYour pillar 3a provider's confirmation of what you paid in during the year. Without it you cannot prove the deduction.Where you see itOne per 3a provider, sent in January.Open in the glossary →), the document your return is built from. In Zurich the amount goes in box 14, one line per spouse, certificate attached. Only what you actually paid during the year counts.

Hold more than one 3a account and the amounts add together against a single maximum. No provider sees what you paid into the others.
The 31 December deadline
The most common and most expensive 3a mistake is a late payment.
To count for tax year 2025 the money must reach your 3a account by 31 December 2025: credited, not ordered, not in transit. Start a transfer on 30 December that settles on 2 January and it counts for 2026.
There is no grace period. The contribution deadline is fixed to the calendar year and a filing extension does not move it. Banks warn customers in mid-December; treat the practical cut-off as a few working days before the 31st, especially over the holidays.
Until now a missed year was simply gone. That is what changes from 2026.
How does the new 2026 catch-up rule work?
A change to BVV 3 in force from 1 January 2025 allows retroactive contributions for years you did not pay in full, under Art. 7a and 7b. It is narrower than most people expect. All four of the following limits apply at the same time:
- Only gaps from 2025 onward count. The transitional provision to the 6 November 2024 amendment bars anything earlier, so every year before 2025 is permanently lost.
- The first catch-up is possible in 2026, since a 2025 gap cannot be filled until 2025 is over. From there you can go back up to 10 years, and that window moves forward each year.
- One catch-up per gap year. A single payment can cover more than one gap year, but the CHF 7,258 ceiling still applies to that payment.
- No catch-up after you have drawn a 3a old-age benefit.
So in 2026 a pension-fund member can pay CHF 14,516: the ordinary CHF 7,258 plus up to CHF 7,258 filling the 2025 gap.
- 1The gap year is 2025 or laterAnything earlier cannot be filled at all
- 2You had AHV-liable income in that yearIncome subject to old-age and survivors' insurance
- 3You pay the current year in full firstThe ordinary CHF 7,258, before any catch-up
- 4Then the catch-up, cappedCHF 7,258 in the year you pay, and never more than you underpaid
Every condition must be met; miss one and the payment is not deductible. Your provider checks them before accepting the money (BVV 3 Art. 7b).
Practical takeaway: pay as much as you can each year, and pay it on time. A year you underpay from 2025 onward can still be topped up later; an earlier one cannot.
If you are taxed at source
This is the limitation that most often affects expats. Tax at source (QuellensteuerQuellensteuerTax at source (withholding tax on salary)FRimpôt à la sourceITimposta alla fonteTax your employer deducts from each salary payment and pays to the canton for you. The rate is a cantonal average that assumes standard deductions, so it ignores your individual ones.Where you see itA deduction line on your monthly payslip, and a total on the salary certificate.Open in the glossary →, the default on most B and L permits) follows a standard tariff that does not account for your 3a contributions, so paying in does not reduce your withholding by itself.
To get the benefit you generally file for an ordinary assessment (nachträgliche ordentliche VeranlagungNachträgliche ordentliche VeranlagungSubsequent ordinary assessment (NOV)FRtaxation ordinaire ultérieure (TOU)ITtassazione ordinaria ulteriore (TOU)Moving from tax at source into the ordinary system, so you file a full return and claim real deductions. Mandatory above certain thresholds, and permanent once you opt in voluntarily.Where you see itApplied for with the cantonal tax office by 31 March.Open in the glossary →) and claim it there. That choice carries forward into later years, so understand it before opting in. See claiming 3a when you are taxed at source.
Expect the money back late, not this year. Filing does not change your monthly withholding; the deduction is settled when the canton assesses the return, and a source-taxed assessment in Zurich commonly takes two to three years.
Withdrawing your 3a
Pillar 3a is tied, meaning you cannot withdraw it whenever you like. Under BVV 3 Art. 3 the standard cases where you can draw on it are retirement (at the earliest five years before the reference age, Referenzalter), leaving Switzerland permanently, buying or building your own home, becoming self-employed, or paying into your pension fund.
The payout is taxed separately from your other income, at a reduced rate (KapitalauszahlungssteuerKapitalauszahlungssteuerLump-sum withdrawal taxFRimpôt annuel entier sur les prestations en capitalITimposta annua intera sulle prestazioni in capitaleA separate, reduced-rate tax charged when you withdraw pillar 2 or pillar 3a capital. Staggering withdrawals across years usually lowers the total.Where you see itAssessed separately from your ordinary return, in the year of withdrawal.Open in the glossary →) rather than added to that year's taxable income. The rate depends on the canton and the size of the payout.
This is why holding several 3a accounts can help: withdraw them in different calendar years and each payout is taxed on its own, instead of one large sum reaching the higher rate steps. Rules vary by canton, so check yours before relying on it.
For what else you can claim alongside 3a, see Zurich tax deductions.
Common mistakes
- Transferring on 30 December. The money must arrive by 31 December. Bank transfers over the holidays often do not.
- Assuming source tax already covers it. The withholding rate uses standard deductions. Your 3a is not among them unless you claim it.
- Paying in more than the cap. The excess is not deductible and the provider may return it. CHF 7,258 is the limit with a pension fund.
- Forgetting the attestation. Your provider sends a contribution certificate. Without it you cannot prove the deduction.
- Withdrawing everything in one year. Withdrawals are taxed separately at a reduced rate, and staggering accounts across years usually lowers the total.
Common questions
How much can I pay into pillar 3a in 2025?
If you are in an occupational pension fund (Pensionskasse): CHF 7,258 for 2025, and the same for 2026. If you are not, whether self-employed or simply not enrolled: 20% of earned income, capped at CHF 36,288.
What is the pillar 3a deadline?
The money has to be credited to your 3a account by 31 December of the tax year. There is no grace period, and a filing extension does not move it, so allow a few working days before the 31st for the transfer to settle.
Can I pay into past years I missed?
From 2026, but only for gaps from 2025 onward. Nothing earlier is recoverable. Up to 10 years back, you must first make the current year's full contribution, and you need AHV-liable income in the years you fill. Each catch-up is capped at the ordinary limit for the year you pay in (CHF 7,258 in 2026) and at what you actually underpaid.
Can I deduct 3a if I am taxed at source?
Not automatically. The source-tax tariff ignores 3a, so claiming it generally means filing for an ordinary assessment (nachträgliche ordentliche Veranlagung).
How is a pillar 3a withdrawal taxed?
Separately from your other income, at a reduced rate (Kapitalauszahlungssteuer) rather than added to it. The rate depends on your canton and the size of the payout.
How PaperTax helps
Upload your documents and PaperTax reads them, then walks you through your own cantonal tax app one document at a time. It tells you what to type and where, in English. It does not file for you. How it works.
This article is general information, not tax, legal, or financial advice. Swiss tax rules vary by canton and by personal situation, and they change. PaperTax helps you complete your own official cantonal tax return. It does not file on your behalf. For advice on your specific situation, consult a qualified Swiss tax professional or your cantonal tax office.
