I have some assets (crypto and stocks) which I bought 3-4 years ago. I have not yet declared these assets to the Swiss tax authorities, I am a B permit holder and therefore am taxed at source. How should I declare these assets considering the fact that I bought them quite some years ago? Is it fine to simply just declare the assets and therefore pay the wealth tax for that year, or will I have to pay wealth tax for the years prior?
I don’t really want to evade paying taxes, it just turns out that my initial investment has accrued in value since then, and I would like to sell some of them soon.
