[Protect & pass on](https://www.helvate.ch/en/insights/categorie/protect-pass-on)# Pillar 3a and 3b: understanding the differences to make the right choice Pillar 3 supplements the benefits of AVS and occupational pension provision. But behind this name lie two very different solutions: pillar 3a, which is regulated and tax-advantaged, and pillar 3b, which is freer and more flexible. Building up private pension provision helps you prepare for retirement, build capital and, depending on the solution chosen, also protect your loved ones or your financial capacity. The choice between 3a and 3b therefore depends as much on taxation as on your goal, your investment horizon and your need to access your money freely.

It is open to people who earn income from gainful employment subject to AVS. In the event of a temporary interruption of work, particularly due to unemployment or illness, the right to contribute may be maintained when the person receives replacement income subject to AVS. Contributions are deductible from taxable income within the legal limits. In 2026, a person affiliated with a pillar 2 pension fund can pay in up to CHF 7,258. Without pillar 2 affiliation, the limit is 20% of relevant income, up to a maximum of CHF 36,288. In return, the money is not freely available. The capital can normally be withdrawn at the earliest five years before retirement age, with early withdrawal options provided by law, in particular to buy a main residence, to leave Switzerland permanently, to become self-employed, for certain pillar 2 buy-ins or in certain cases of disability. The capital withdrawn is taxed separately from other income. ## Pillar 3b: more freedom Pillar 3b refers to unrestricted pension provision. It can take different forms: savings, investments or life insurance. There is no statutory annual contribution limit, and the capital generally remains available according to the terms of the chosen product. Unlike pillar 3a, contributions do not qualify for an annual tax deduction, except in the cantons of Geneva and Fribourg, which offer tax advantages that are nevertheless limited compared with those of pillar 3a. ## Bank or insurance: two different approaches A pillar 3a can be set up with a bank or an insurance company. The bank solution is mainly geared towards saving and investing and generally offers great flexibility in the amount and frequency of contributions. A pillar 3a with an insurer combines building up retirement capital with cover for certain risks. Depending on the policy, benefits may be provided in the event of death or incapacity to work. In return, the policyholder undertakes to pay regular premiums, often monthly, for the entire term of the policy. This required regularity can provide a disciplined framework, which appeals to people who want to build their pension provision steadily over the long term. The choice therefore depends on your goal: prioritising the flexibility of savings, or combining capital building with insurance protection. ## New since 2026: catching up on missed pillar 3a contributions Since 2026, certain gaps in pillar 3a contributions that have arisen since 2025 can be filled at a later date. Retroactive buy-ins are possible for up to ten years. However, they are subject to several conditions: in particular, you must have been entitled to contribute in the year concerned, be entitled to contribute in the year of the buy-in and have first paid the maximum ordinary contribution for that year. The annual buy-in amount is itself capped at CHF 7,258 in 2026. ## What about cross-border workers? Cross-border workers working in Switzerland can also supplement their pension provision with a pillar 3a or 3b. For pillar 3a, specific conditions apply, particularly regarding AVS coverage and tax deductibility. For pillar 3b, the options depend in particular on the chosen solution, the insurer and the country of residence. Personalised advice is therefore the best way to determine the right solution for a cross-border worker's situation. ## 3a, 3b or both? Pillar 3a primarily serves a long-term retirement savings goal combined with a tax advantage, while pillar 3b offers more freedom in how you build and use your assets. The two can also complement each other and be taken out at the same time.
