Our cooperation brings you to the next level


A good example to illustrate the cooperation between RSM Payroll and HR Solutions and the tax consultants is the application of the research & development withholding tax exemption. 

One of Belgium’s objectives is to dedicate part of the GDP to R&D. Considering the important role of companies in this respect, several fiscal measures exist to stimulate R&D. One of these measures is the R&D withholding tax exemption. This states that a company is exempt from transferring up to 80% of the tax withheld from the employees’ salaries to the Belgian tax authorities. Certain requirements with respect to the companies and the employees should be fulfilled. 

While the tax consultants offer your company guidance in obtaining and maintaining this benefit, RSM Payroll and HR Solutions takes care of the practical implementation in the payroll, together with the tax consultants.
