Just wondering what the latest situation is in Sweden with regards to Futures day trading. I'm currently in London trade via a UK limited company and a US-based brokerage account. I'm considering moving to Stockholm and was wondering what the tax implications are. In the UK I pay about 19% Corporation tax and higher rate 32.5% tax on dividends (I have another company where I get my main income and salary) - so any dividend extracted would be at a higher rate or more. I've read that dividends are taxed at a flat rate of 30% in Sweden - is this the case even if you day trade or is it taxed as regular income? If day trading is your sole income how is your social security contributions calculated? are there any local/municipal taxes I need to be aware off.
