I understand that there are no taxes on capital gains (non-professional investor).
Let’s say I buy CHF 10k of a few stocks. With a few losses and a few more wins, I sell after several months by, say, CHF 11k, so 1k profit.
I still need to declare this 1k profit somewhere in my tax declaration, and that will count towards my overall revenue and consequent % of tax, right?
No, there are no taxes, assuming you’re not classified as a pro investor, you just report the balance at end of year and the income from dividend.
Yes, I usually provide it (mostly because it’s convenient for me to double check my numbers), but know many people who don’t. If they want more detailed data, they’ll ask for it anyway.
In any case it doesn’t affect your tax owed.
