It is taxable indeed: ICTax - Income & Capital Taxes
Accumulation versus distribution has no effect on taxation in Switzerland.
I can think of only two securities I held in the past, that weren’t taxed:
- Berkshire Hathaway, because back then, we didn’t have access to many good, diversified funds as we do now, and unfortunately I held the horribly carbon-intensive BRK.
- And BOXX, as a convenient way to have fixed income for the short term, before Trump II and the dollar fall.
