Social insurance contributions are generally payable by the employee and employer when an option is exercised.

A Medicare levy is payable by the employee when an option is subject to income tax on the amount included in taxable income. An additional Medicare levy surcharge may also be imposed on higher-income employees without appropriate health insurance.

Social insurance contributions are payable on the spread and are subject to a cap. Withholding is required.

Generally, the spread is not subject to social insurance contributions, provided at least they are not granted by the employer of the beneficiary. The notion of "granting" should in this regard nevertheless be construed in a broad sense, and it covers both the situations where the employer directly pays the benefit, the situation where the employer indirectly pays the benefit because the parent company granting it charges the cost for doing so to the employer, but also covers the situation where the employer does not bear the financial cost of the benefit but intervenes in the granting of the benefit. For stock options, stock options meeting all conditions stipulated in the Act of March 26, 1999 are nevertheless exempt from social security contributions.

Similar to the rationale adopted for income tax mentioned above, the social insurance consequences are also marked by controversy and depend on the characterization of the plan.

Whenever the stock option plan is treated as a commercial/mercantile transaction, it would be no be subject to social insurance contributions upon grant nor exercise.

If the stock option plan is treated as an employment benefit/remuneration, stock options may be subject to social insurance contributions upon exercise, particularly in case payment or reimbursement is made by the Brazilian subsidiary.

This matter is currently pending before the Superior Court of Justice, which, in 2025, admitted Repetitive Theme 1.379 to determine whether social insurance contributions apply at the moment the option to purchase shares is exercised under a stock option plan. The Superior Court ordered the suspension of all pending cases before lower courts until a final decision is issued on this topic.

Generally, social insurance contributions, which are based on an employee's compensation and are subject to a cap, are payable on the spread when an option is exercised.

Remunerations derived from stock options plans are subject to social security contributions if, together with the remaining remunerations payable to the eligible employee in the same month period, do not exceed the capped compensation that law states as a basis for social security calculations. For instance, if the base salary of an eligible employee suffices on the capped basis, compensation from the plans paid in the same period will not be subject to social security contributions since they are over the capped basis. Otherwise, if compensation of the plan, together with the remaining remunerations payable in the month, is lower than the capped month basis, they shall trigger social security contribution payments. In addition, should the benefits be paid directly by the issuing company with no charge-back to the local employer, it is debatable if they will trigger social security contributions obligations.

Social insurance contributions may be imposed on the spread.

If the stock options are granted as a non-salary payment, they would not be included in the basis to calculate social security contributions, provided that such payments do not exceed 40 percent of the employees' total monthly compensation. If these non-salary payments exceed that 40 percent of the monthly compensation, the excess will be subject to social security contributions.

The basis to calculate contributions to the social security system (pensions, solidarity pension fund, health and labor risks) is the monthly salary earned by the employee. If that monthly salary exceeds 25 times the minimum legal wage, contributions to the social security system will be calculated on the maximum basis of 25 times the minimum legal wage.

In case of employees earning a so-called "integral salary," 70 percent of salary will be the basis to calculate contributions to the social security system.  However, if 70 percent of the integral salary is more than 25 times the minimum wage, contributions to the social security system will be calculated on the maximum basis of 25 times the minimum wage.

Generally, social security and health insurance contributions do apply when the employee acquires shares or RSUs in the employer or in a parent, subsidiary or other capital-connected company.

Such benefits are deemed to constitute accounted-for income of the employee in the calendar month in which the certain event occurs (as described in the “Tax” section) or, as applicable, upon the sale of the shares, and are therefore included in the assessment base for social security and health insurance contributions.

By contrast, qualified employee stock options are not deemed to constitute accounted-for income for social security and health insurance purposes. Consequently, the acquisition or exercise of qualified employee stock options does not form part of the assessment base, and social security and health insurance contributions do not apply.

For the sake of completeness, social security and health insurance contributions also do not apply provided that:

• The Czech employer is not responsible for the cost of the plan ( ie, there is no reimbursement of costs)

• The shares of the Czech employer are not included in the plan and

• Payments are not made through the Czech employer.

There is no social insurance scheme per se for Malaysia but there is a mandatory requirement for contributions to the Employees' Provident Fund (EPF) for all employees who are Malaysian citizens. There is also a mandatory requirement for employers to contribute to the Social Security Organisation (SOCSO) and this is applicable to both local and foreign employees. The requirement to contribute to the EPF and SOCSO is based on a percentage of wages. So far as the plan is carved out and not made a term of the employment contract and does not form part of wages, there is no requirement to contribute to EPF or SOCSO based on the employee's entitlement to the stocks.
