A self-employed person who belongs to no pension fund may pay into pillar 3a up to 20 % of their net earned income, capped at 36'288 francs in 2026 — five times an employee's contribution. This is the “large contribution”, and it is fully deductible. It disappears as soon as a 2nd pillar exists, even a voluntary one: the owner of a Sàrl or an SA, an employee of their own company, falls back to 7'258 francs. Pillar 3a for the self-employed is therefore the main deductible pension instrument available to a sole proprietorship, and one of the few that can be made fully compliant.
Being self-employed in Switzerland means having no compulsory 2nd pillar. No one deducts BVG/LPP contributions from your profit, no one builds up retirement capital on your behalf. The law offsets that absence with an enlarged pillar 3a. Here is how pillar 3a for the self-employed works, who exactly is entitled to it, what it is worth in tax, how it compares with voluntary BVG/LPP membership, and how to make it halal.
What changes for a self-employed person?
A person who is self-employed within the meaning of the OASI (AHV/AVS) is not subject to compulsory occupational pension provision. The BVG/LPP covers employees only; someone trading as a sole proprietorship pays OASI contributions on their income, but nothing obliges them to build up a 2nd pillar. They may join one voluntarily — we come back to this — but by default their retirement rests on the OASI and on what they save themselves.
This is the situation addressed by Article 7 of the OPP 3 ordinance (RS 831.461.3): people without a 2nd pillar benefit from a much higher 3a contribution cap, calculated as a percentage of their income. The mechanism is the same as for employees — tied pension, tax deduction, capital locked until retirement — but the scale changes.
What is the pillar 3a cap for the self-employed in 2026?
The maximum contribution is 20 % of net income from self-employment, with an absolute cap of 36'288 francs — five times the small contribution of 7'258 francs, according to the figures published by the Federal Social Insurance Office, unchanged from 2025.
The relevant income is the net profit from self-employment, after deduction of AVS/AI/APG contributions (old-age, invalidity and loss-of-earnings insurance) — as it appears in the accounts and in the tax assessment, and not turnover. That is the reading adopted by circular no. 18 of the Federal Tax Administration on the taxation of pillar 3a, supplemented by circular 18a of December 2025. The cap of 36'288 francs is reached at a net income of 181'440 francs; below that, the 20 % rule applies.
| Net earned income (after OASI) | Maximum 3a contribution 2026 | For comparison: employee with BVG/LPP |
|---|---|---|
| 40'000 CHF | 8'000 CHF | 7'258 CHF |
| 60'000 CHF | 12'000 CHF | 7'258 CHF |
| 120'000 CHF | 24'000 CHF | 7'258 CHF |
| 181'440 CHF and above | 36'288 CHF Cap | 7'258 CHF |
One practical subtlety: the final net income is known only when the accounts are closed. A self-employed person who pays in 20 % of an estimated profit and ends the year below it will be refused the deduction on the excess, which the foundation then refunds. The prudent approach is to pay in a base amount during the year and the balance in December, once the result is clear.
Sole proprietorship or Sàrl: who is entitled to the large contribution?
Only a person recognised as self-employed by their AVS compensation fund — in practice, a sole proprietorship or the partner in a partnership — is entitled to the large contribution. The owner of a Sàrl or an SA is an employee of their company: as soon as their annual salary exceeds the BVG/LPP entry threshold of 22'680 francs, membership of a pension fund is compulsory, and their pillar 3a falls back to 7'258 francs.
This is one of the least well understood trade-offs when setting up a business. The Sàrl protects private wealth and allows a generous 2nd pillar — of which the employer, that is to say you, pays at least half the contributions — but it closes off the large 3a. The sole proprietorship exposes private wealth, but opens up 36'288 francs of deduction with no pension plan constraints at all. Neither is “better”: everything depends on income, on the risk of the activity and on how much value you place on controlling your investment vehicles.
Voluntary BVG/LPP or the large 3a: which to choose?
A self-employed person may join a pension fund voluntarily — their industry fund, their staff's fund or the Substitute Occupational Benefit Institution — but doing so immediately brings their pillar 3a back to the small contribution. The choice is therefore exclusive: either a voluntary 2nd pillar and 7'258 francs of 3a, or no 2nd pillar and up to 36'288 francs of 3a.
Voluntary BVG/LPP has its arguments: deductible buy-backs potentially well above 36'288 francs at a high income, integrated death and disability cover, and protection of the capital from creditors. The large 3a has others: no imposed plan, no fund charges, complete freedom of investment vehicle, and capital that remains yours at every moment. For most self-employed people earning less than 200'000 francs, the large 3a wins on simplicity and on deduction; above that, BVG/LPP membership deserves to be costed.
| Criterion | Large 3a (without BVG/LPP) | Voluntary BVG/LPP + small 3a |
|---|---|---|
| Annual deduction | Up to 36'288 CHF | Contributions + buy-backs, often more at a high income, plus 7'258 CHF of 3a |
| Choice of investment vehicles | Free: account, securities, screened funds | Decided by the fund |
| Death / disability cover | To be taken out separately | Included in the plan |
| Charges | Those of the chosen vehicle | The fund's administration and risk charges |
| Islamic compliance | Can be made compliant Yes | The fund's bond portfolio No |
The last line is no detail for our readers: a pension fund invests a large share of its assets in bonds and interest-bearing cash, and the insured member has no say in those choices. The large 3a, by contrast, can be screened.
How much tax does a self-employed person save?
Every franc paid into pillar 3a for the self-employed is deducted from taxable income in the year of payment; the saving is therefore the amount paid in multiplied by your marginal tax rate. For a self-employed person in French-speaking Switzerland declaring 120'000 francs of net income, that marginal rate — federal, cantonal and communal — generally sits between 30 and 40 %. A contribution of 24'000 francs then represents in the order of 7'000 to 9'500 francs less tax, depending on the canton and the municipality.
Our pillar 3a tax-saving calculator includes the tax scales of all 26 cantons and the case of the self-employed person without BVG/LPP. Two effects to keep in mind: a deduction of this size often moves you into a lower bracket, so that the last francs paid in are deducted at a slightly lower rate than the first; and the capital will be taxed on withdrawal, at a reduced rate — see our guide to withdrawing pillar 3a. Over time, the gap between the two rates remains very largely in favour of paying in.
Knowing your own ceilings
Determining income, the large 3a, voluntary BVG/LPP: the rule depends on your status and can be checked in the legislation. The ALG Club programme shows you where to find it and how it applies. A first conversation, with no obligation, to find out about the programme.
Discover the programmeDoes the retroactive contribution apply to the self-employed?
Yes, but with a cap that comes as a surprise: the retroactive contribution for one year's gap is limited to the small contribution, 7'258 francs, even for a self-employed person whose ordinary contribution reaches 36'288 francs. Article 7a OPP 3, in force since 2025, draws no distinction between the two regimes on this point.
In concrete terms, a self-employed person without BVG/LPP who paid nothing in 2025 may, in 2026, pay their ordinary contribution — up to 36'288 francs — then make a retroactive contribution of 7'258 francs for 2025, that is up to 43'546 francs deductible in a single year. The conditions and the procedure are set out in our guide to retroactive contributions to pillar 3a, and our 3a retroactive contribution simulator quantifies the effect canton by canton.
How can pillar 3a for the self-employed be made halal?
The legal framework of pillar 3a is neutral; what determines compliance is the form of the contract and the vehicles it holds. An interest-bearing 3a account produces interest — riba — whatever its size, and at 36'288 francs a year the base grows quickly. A 3a insurance policy combines a guaranteed technical interest rate, contractual uncertainty and bond reserves. That leaves the securities-based bank 3a, whose portfolio is yours to choose: it is the only form that can be made fully compliant.
The method is the one we apply to all pension planning: open the contract with a banking foundation that gives access to funds or to individual securities, then screen according to the AAOIFI ratios — interest-bearing debt below 33 %, interest-bearing cash below 33 %, non-compliant income below 5 % — and purify each year the non-compliant share of dividends. Our guide to the halal pillar 3a sets out the criteria, and our comparison pillar 3a: bank or insurance explains why the policy is not an option.
The ALG Club programme sets out this method step by step: where a bank pillar 3a in securities can be opened, how a fund's composition is read, how the ratios apply and how the annual purification is documented. The choice of contract and of institution remains yours: ALG Club distributes no pension or insurance product and takes no part in any subscription.
Mistakes to avoid
Four mistakes recur in the self-employed files we see.
Paying in 20 % of an income that is not yet known
The excess is refused as a deduction and refunded, with a tax year lost. Pay in a base amount, then adjust in December.
Joining a voluntary BVG/LPP “for the cover” without measuring what it closes off
Membership brings the 3a back to 7'258 francs in that same year. Death and disability cover can also be taken out separately, without giving up the large contribution.
Choosing a policy with a fixed premium when income varies
A self-employed person's income fluctuates; an annual premium committed over twenty years does not adapt. A bank 3a is paid into when you can, to the extent that you can — and it can be made compliant.
Forgetting that the capital stays locked
The large 3a is not a cash reserve. The grounds for early withdrawal are limited — taking up self-employment is one of them, within the following year, but the company's liquidity needs are not. An operating reserve is built up alongside, not inside pillar 3a for the self-employed.
