Pillar 3a or 3b: what is the difference — and which suits you?
Both belong to the third pillar, but fiscally they are worlds apart: pillar 3a rewards you immediately with a tax deduction but locks the money away until retirement. Pillar 3b stays available at any time — in return, you pay in from already-taxed money.

The same goal, two rulebooks
The third pillar is private retirement provision — and it has two compartments. Pillar 3a (“restricted provision”) is state-sponsored and therefore regulated: contribution limit, lock-up, fixed withdrawal rules. Pillar 3b (“flexible provision”) is simply everything else you put aside for old age: savings account, securities portfolio, life insurance — no sponsorship, no shackles.
Pillar 3a: deduction in exchange for lock-up
- Deduction: contributions are deductible from taxable income — in 2026 up to CHF 7,258 with a pension fund, without one 20% of earned income up to CHF 36,288. What that saves you in francs: pillar 3a calculator.
- During the term: no wealth tax on the balance, no income tax on the returns.
- Lock-up: withdrawal at the earliest five years before the AHV reference age. Earlier access only for home ownership, self-employment, definitively leaving Switzerland, or disability.
- Payout: capital withdrawals are taxed separately from other income at a reduced rate. Spreading the money over several 3a accounts and withdrawing them in different years breaks the progression — see the guide staggered pillar 3a withdrawal.
Pillar 3b: freedom without sponsorship
- No deduction: contributions come from taxed income. There is no federal 3b deduction; a few French-speaking cantons (notably Geneva and Fribourg) allow limited exceptions for insurance solutions.
- Taxed continuously: 3b assets are subject to wealth tax, interest and dividends to income tax.
- But flexible: no maximum, no minimum age, available at any time — including for goals before retirement (education, property abroad, a sabbatical).
- Payout: tax-free for savings and investment solutions; subject to conditions for life insurance.
The comparison at a glance
| Pillar 3a | Pillar 3b | |
|---|---|---|
| Tax deduction | yes (annual maximum) | generally no |
| Wealth tax | no | yes |
| Availability | locked until ~5 years before reference age | any time |
| Contribution limit | yes | no |
| Payout | reduced rate, separate | generally tax-free |
What does that mean in practice?
For most working people the order is: first 3a up to the maximum — the immediate deduction plus the tax-free term are hard to beat. Then 3b for everything that should stay flexible. Pillar 3b is also the only option for people without AHV-liable earned income, who cannot open a 3a.

Frequently asked questions
Can I pay into pillar 3b once the 3a maximum is used up?
Yes — pillar 3b has no contribution limit. The usual order is exactly that: first exhaust the 3a maximum (2026: CHF 7,258 with a pension fund), because that is where the tax deduction lies, then save or invest freely in 3b.
Is the pillar 3b payout tax-free?
Capital from pure savings and investment solutions in pillar 3b is free of income tax at payout — it was taxed continuously along the way (income at contribution, wealth tax, tax on returns). For 3b life-insurance policies, tax-free treatment is subject to conditions; the policy and cantonal practice are decisive.
Does pillar 3a count toward taxable wealth?
No — 3a assets are exempt from wealth tax during the term, and their returns remain untaxed. 3b assets, by contrast, are declared annually in the tax return, and interest/dividends are taxable income.
