Well, in my case things are more complex as I have done some manufactured spending with gift cards, which I now regret since it adds a lot of complexity without any serious financial gain, it was more like a weird hobby and out of curiosity. I have proof for everything with credit card and bank account statements, so there is nothing illegal, just too complex. Anyway you convinced me to declare everything and see what happens. I suspect there will be a lot of letters back and forth with the tax office.
