A self-employed person has no mandatory 2nd pillar. In practice, they do not automatically contribute to a pension fund: their retirement rests on the OASI and on what they set aside themselves. This is what makes the 3rd pillar the central pillar of pension planning for the self-employed, and one of the most powerful tax-optimisation tools available to them.
The big advantage: a much higher cap
Most employees are limited to CHF 7,258 of deductible pillar 3a per year. A self-employed person not affiliated with a pension fund, however, can pay in up to 20% of their net professional income, capped at CHF 36,288 per year in 2026, and deduct the entire amount from their taxable income. That is nearly five times an employee's cap.
One nuance to watch: if you are affiliated with a pension fund (for example through a professional association or a voluntary membership), the CHF 7,258 cap applies, as for an employee. The higher CHF 36,288 cap is reserved for the self-employed without a 2nd pillar.
Why it is particularly worthwhile
- An immediate tax saving: every franc paid in reduces your taxable income, and therefore your income tax and, in some cases, your contributions.
- Retirement capital you control: with no 2nd pillar, the 3a builds the part of your retirement the OASI will not cover.
- Protection when things go wrong: through an insurance solution, the 3a can cover death and incapacity to work — valuable security when you don't have an employer's cover.
- Flexibility: your contributions adapt to a business whose income varies from year to year.
3rd pillar or optional 2nd pillar?
A self-employed person can also choose to join a pension fund (2nd pillar) voluntarily. Each has its logic: the large 3a offers more flexibility and capital you steer, while the optional 2nd pillar allows substantial buy-ins and, for high incomes, sometimes a larger deduction. The right trade-off depends on your income, its stability, and your wealth goals. This is exactly the kind of choice a personalised comparison helps clarify.
The 3a capital is exempt from wealth tax throughout the term of the contract, then taxed at the time of withdrawal, separately and at a reduced rate. For a large amount, spreading it over several years often reduces the final tax bill.
Self-employed in Geneva or a cross-border worker?
If you are based in Geneva, the high cantonal tax scale makes the deduction even more rewarding: see our guide to the 3rd pillar in Geneva. And if you work as self-employed while living in France, your situation involves both self-employed status and cross-border rules: our cross-border guide explains the quasi-resident condition.
