However, i.e. in Germany there is no differentiation between longterm and short-term capital gains and day-trading income will only be subject to 25% capital gains, regardless how long you hold the asset and how big your position is.
Does somebody know alternative countries where regular capital gains tax apply, even for daytrading income?
That goes for Sweden for sure. 30% capital gains tax irrespective of volume of trading or how long you hold the assets. Sweden also have something called "investment saving account" with much lower taxation, but only for long trading and only with local brokers.
Are you sure that you are not taxed as business income in Germany, if you reach a certain volume and frequency of trading?
