# Pillar 3a vs 3b in Switzerland: Differences, Tax Benefits & Best Providers

**Quick answer:** Yes. Pillar 3a gives you the tax deduction up to the annual cap; Pillar 3b is unrestricted and can be used in parallel for any additional saving or insurance.

The Swiss pension system rests on **three pillars**: state AHV (Pillar 1), occupational pension (Pillar 2), and private pension (Pillar 3). Pillar 3 is where you take control — and where every Swiss resident should pay attention.

## Pillar 3a — tax-privileged retirement savings

Pillar 3a (_gebundene Vorsorge_) is a restricted retirement account with major tax benefits. In 2026 employees can contribute up to **CHF 7,258**; self-employed without a Pillar 2 can contribute up to **20% of net income**, capped at CHF 36,288.

  - **Fully deductible** from federal, cantonal, and communal income tax.

  - **No wealth tax** on the balance, no income tax on returns.

  - Withdrawal restricted to retirement, buying a primary residence, leaving Switzerland, becoming self-employed, or full disability.

## Pillar 3b — flexible private savings

Pillar 3b (_freie Vorsorge_) covers any private saving or insurance product without the contribution cap. There is no federal tax deduction (a few cantons grant small ones), but you have **full flexibility** on when and how to withdraw.

## Digital providers vs traditional banks

Banks like UBS, ZKB or PostFinance still dominate Pillar 3a, but their fund fees often exceed 1% per year. Modern app-based providers offer index-based 3a portfolios with 99% equity allocation and low TER:

  - **VIAC** — fees from 0.44%, up to 99% equities, integrated with Bank WIR.

  - **Finpension 3a** — fees ~0.39%, institutional Swisscanto funds, up to 99% equities, 5 portfolios per user.

  - **Frankly** (ZKB) — clean app, fees 0.44%.

  - **Truewealth 3a** — passive ETF strategies.

Over 30 years, switching from a 1.2% bank fund to a 0.4% digital 3a can mean **tens of thousands of francs** in extra retirement capital.

## How to optimise withdrawal

Open **multiple 3a accounts** (typically 3–5) and stagger withdrawals across different tax years to break tax progression. Withdrawals are taxed separately at a reduced rate, but cumulative amounts in the same year push you up the scale.

## Bottom line

Use Pillar 3a aggressively for the tax deduction and long-term equity growth. Use Pillar 3b for flexibility, life insurance bundles, or surplus savings beyond the 3a cap. Track all your pension assets — including 3a balances at VIAC, Finpension and your bank — alongside your everyday accounts in [Finch](/).

## FAQ

**Can I have both Pillar 3a and 3b?**

Yes. Pillar 3a gives you the tax deduction up to the annual cap; Pillar 3b is unrestricted and can be used in parallel for any additional saving or insurance.

**How many Pillar 3a accounts should I open?**

Most experts recommend 3 to 5 accounts so you can withdraw them in different tax years and reduce the lump-sum tax.
