Taxation of stock option sales on social shares under Personal Income Tax

The granting of stock options on social shares to employees constitutes a compensation tool that carries specific tax implications for Personal Income Tax (IRPF). A recent binding ruling from the Dirección General de Tributos (DGT) has delimited the treatment applicable to these operations.

What the DGT has ruled

The tax authority establishes that the free granting of a stock option to an employee, motivated by their status as such, is classified as employment income in kind. The accrual of this income occurs at the moment the option is exercised.

To determine the amount of this income, the positive difference between the agreed transfer value and the market value of the share at the time of exercise must be calculated. On the other hand, the difference existing between the market value of the share and its acquisition value constitutes, in turn, a capital gain or loss.

What it means for you

If you are an employee who holds stock options on shares of the company where you provide services, you must consider that the operation has a dual tax aspect:

• Employment income: The benefit obtained by the mere fact of being able to sell at a price lower than the market price will be taxed as employment income.
• Capital gain: The benefit derived from the difference between the market value and the acquisition cost of the shares will be taxed in the savings tax base.

It is relevant to note that this employment income could be subject to the reduction provided for in Article 18.2 of the LIRPF, provided that the requirements regarding the generation period and the quantitative limits established by the regulations are met.

What should be done

Given the complexity of determining the market value and the coexistence of two types of income, it is necessary to analyze each situation individually. The correct determination of values is fundamental to avoid errors in the tax settlement. It is recommended to assess each particular case to ensure that the valuation criteria and possible applicable tax reductions are correctly applied.
