The idea: don't put all your eggs in one 3a
Nothing forces you to concentrate your whole 3a in a single contract. You can open several 3a accounts or policies and split your contributions across them. The point isn't to save more (the ceiling stays global), but to organise your future withdrawals intelligently and keep room to manoeuvre.
Smoothing tax on withdrawal
On withdrawal, 3a capital is taxed via a one-off tax whose rate is progressive: the higher the amount withdrawn in a single year, the higher the rate. By holding several contracts and withdrawing them in different years, you split the taxable capital and reduce the rate applied. It's one of the rare legal and effective levers on exit taxation.
Flexibility for your projects
Several contracts also mean the freedom to mobilise one for a project — for example buying your main home — while leaving the others to keep growing and enjoying their advantages. You thus avoid emptying all your provision at once for a single goal.
How many accounts to open?
Two to three contracts usually cover most of the tax benefit, without multiplying fees and paperwork. Beyond that, the marginal gain shrinks. Ideally, calibrate the number of accounts to your retirement horizon and interim projects (property purchase, becoming self-employed, leaving Switzerland).
The pitfalls to avoid
- Exceeding the global ceiling: the total paid across all your 3a cannot exceed the annual limit (CHF 7,258 in 2026 for an employee).
- Multiplying fees: too many small contracts can cost more than they earn.
- Withdrawing several contracts in the same year, which cancels the benefit of staggering.
A worked example
Imagine total capital of CHF 150,000 at retirement. Withdrawn at once, it faces the one-off tax at the highest rate of the bracket. Split across three CHF 50,000 contracts withdrawn in three different years, each withdrawal is taxed at a lower rate — the saving can reach several thousand francs. The exact amount depends on your canton and situation.
