In Sweden you can invest your money in a special investment account which charges a certain fixed percentage each year on the amount you have in this account (cash and stocks). The percentage is based on the central bank interest rates (a special formula based on that) so it changes each year. In the past 10 years it has been around between 0.5-1% of the total amount you have in this account. Then all the profits you make are tax free as well as no tax on dividends and interest. You can't deduct losses though.
In Sweden there is no wealth tax and no inheritance tax.
EDIT: And for completeness, if you invest outside of the above mentioned type of account you have to pay 30% on profits and 30% on dividends and interests.
But yea, considering I pay close to 50% tax it's remarkable at the same time I can speculate in the market, make 500% and pay 1% tax on it. Or that people with actual money pay so little.
If that's the case, it affects earnings quite a bit. Say your investments beat inflation by 3 percentage points, you're effectively down to 2 percentage points after tax, so a 33% reduction in income.
The current ISK tax is about 3x that of a low tax canton.
You think they pay 56% tax on income like the idiotic peasants?
