Since there is interest again, you have to deal with this advance lump sum with ETFs -.-.
Do you know how it is if you have, for example, an accumulating ETF that is 50% in the red and makes in the next 10 years per year so about 3%, and you then sell it anyway at a loss; Will then the advance lump sum paid over the 10 years in addition to the realized loss in the loss pot, or I have then given the tax office?
