On 13 April 2016 a questionable ruling was passed by the Supreme Administrative Court (hereinafter: SAC) in a case with reference number II FSK 668/14, in which the court ruled that the exercise of stock options and restricted share units received from a company as part of an incentive scheme creates the employee's income. The employee's income is created again when the employee sells the shares. However, he or she will not be able to reduce it by the cost equal to the proceeds from converting the options to shares. In the Tax Alert below we would like to familiarise you with the discussed ruling which practically leads to double taxation of the same income.
