A sample issue

Sunday 25 October 2026

From: ViaVest Subject: The same 3a, 10'800 francs less tax in Geneva

This week's figure: 10'800 francs

That is the tax saved in Geneva on a 3a of 300'000 francs, withdrawn in five parts instead of one. FTA calculator, 2026 rates, single person.

Why

On withdrawal, your 3a is taxed separately, at a rate that rises with the amount withdrawn in the same year. And a 3a account can only be withdrawn in one go. With five accounts, you withdraw one a year, each taxed lower.

How to use it

  1. Count your 3a accounts. Only one? Open a second: online providers offer up to five in the same app.
  2. Send your next payments to the new account: an existing account generally cannot be split later.
  3. When the time comes, do not withdraw a 3a account in the same year as your pension fund lump sum.

Leaving Switzerland one day? The same logic applies: accounts withdrawn in different years cost less tax at source.
