The real question: save or protect?
A bank 3a and an insurance 3a enjoy exactly the same tax deduction. The difference is therefore not fiscal but functional: do you above all want to save while staying free, or protect your family and income in case of a setback? The answer guides the choice.
The bank 3a (or app)
The bank option is a 3a account (or securities portfolio). Its strengths: fully free contributions — you can pay more, less or nothing in a given year with no penalty — generally low fees, and the option to invest in funds to target a better long-term return. On the other hand, it offers no cover in the event of death or disability.
The insurance 3a
The insurance option combines saving and protection. It often includes a waiver of premiums in the event of incapacity to work (the insurer keeps contributing for you if you can no longer work) and a death benefit for your family. In return: regular premiums to keep up, a multi-year commitment, and less flexibility. Cancelling early can lead to a loss.
Bank vs insurance: the table
| Criterion | Bank 3a | Insurance 3a |
|---|---|---|
| Tax deduction | Identical | Identical |
| Contribution flexibility | Total (free) | Fixed premiums to keep up |
| Death / disability cover | No | Yes, included |
| Fees | Generally lower | Higher (insurance part) |
| Commitment | None | Multi-year |
| Best for | Saving while staying free | Protecting your family and income |
How to choose for your profile
Favour the bank if you want flexibility, low fees and steerable savings (variable income, self-employed, young worker). Favour insurance if you have dependants and want to secure your income in case of disability or death (see our page on protecting your family). Many households combine the two: a bank 3a to save, an insurance 3a for protection.
Can you have both?
Yes. You can split your annual 3a ceiling across several contracts, including one bank and one insurance contract. Holding several 3rd pillars even has a tax advantage on withdrawal. The total paid in simply has to stay within the annual limit (CHF 7,258 in 2026 for an employee).
