Employment Tax (IRPF) Master Data 
Purpose
This process describes the maintenance of the relevant master data for calculating employment tax deductions and payments and other deductions for each employee.
Requirements
In the Implementation Guide for Personnel Administration the necessary activities relating to the tax master data, specified under Human Resources Administration ® Payroll Data ® Employment Tax Deduction have been carried out:

You maintain the master data relating to employment tax (IRPF) through the infotypes Tax Data (0062) and ‘Additional Income’ (0090).
The maintenance of the first infotype is obligatory, since without the employee tax data, it is not possible to perform payroll. The standard system provides this infotype for maintenance as part of the personnel action ‘Recruitment’.
The second infotype is not taken into account in payroll, but is used to generate the models 110,111, 190 and 195 for the tax authorities.
To maintain the infotype 0062, fill in the fields corresponding to the following field groups in accordance with the information contained in the description of the infotype
