There are 2 options as of january 2012 here.
1. Normal stock account with 30% capital gains tax.
2. Account without capital gains tax and instead a yearly tax. The yearly tax is derived from: average value of account(measured 4 times a year) + deposits, multiplied with government borrowing rate, this result is taxed(and counted as income from capital) with 30%. No tax filings necessary for stocks. Can´t use losses to offset gains.
Both types are with full ownership of the stocks, unlike an endowment insurance.
