Pillar 3a vs Pillar 3b: locked and deductible, or free and taxed

Updated · 2 sources

Direct answer

Pillar 3a gives you a tax deduction today (up to CHF 7,258 in 2026) but locks the money until 5 years before AHV retirement age, then taxes the payout at a reduced separate rate. Pillar 3b is simply your free savings: no deduction and no lock, interest and dividends are taxed as income yearly, while private capital gains are generally tax-free. Fill 3a first for retirement money; keep everything you may need earlier in 3b.

Key facts

  • 3a: deductible in, locked until age 60 at the earliest, taxed separately at a reduced rate on withdrawal
  • 3b: no deduction, accessible anytime, yield taxed yearly as income; private capital gains generally tax-free
  • 3a early withdrawal only for home purchase, self-employment, leaving Switzerland, disability
  • Order of filling: emergency reserve (3b) → 3a to the limit → further investing (3b)

The order matters more than the product

The deduction makes 3a the strongest legal tax shelter most Swiss employees have: at a 25% marginal rate the full CHF 7,258 contribution saves about CHF 1,800 of tax every year. But money you will need for a home deposit in three years beyond the permitted 3a home-ownership withdrawal, a career break, or a business start does not belong behind the lock.

A workable sequence: build 3–6 months of expenses in a free account (3b), then pay the 3a maximum each year, then invest anything further freely (3b), where private capital gains are generally not taxed as income, provided you are not classified as a professional securities dealer.

FAQ

Is Pillar 3b an official product?
No. 3b is the collective name for all free, non-tied saving and investing: bank accounts, funds, ETFs and life insurance without the 3a tie. There is no 3b contract type and no deduction.
Can I withdraw Pillar 3a to buy a home?
Yes, for an owner-occupied home (purchase, construction, mortgage amortisation or shares in housing cooperatives). The withdrawal is taxed at the reduced separate rate in the year it is paid out.
Are ETF gains taxed in Switzerland?
For private investors who are not professional securities dealers, capital gains are generally tax-free, while dividends and interest are taxable income and subject to 35% withholding tax, reclaimed via the tax return.
What if I leave Switzerland?
Leaving Switzerland permanently is a permitted 3a withdrawal event; the payout is taxed at source at the rate of the fund's canton, which is why some providers domicile 3a foundations in low-rate cantons.
