Infotype
0158 (Amounts paid by third persons) 
Definition
This infotype manages the amounts paid or to be paid to the employee by third persons, and therefore not by the employer with whom the employee has the employment work relationship.
Use
The management of this data is relevant for counting the employee’s taxes for the year-end settlement.
The same is valid for infotype 0305.
Structure
The structure of this infotype is very simple, since it is just made up of wage types which are manually inserted into the system, and which are then read by the program during tax settlement.
The types read in this infotype are:
/4Z1 – IRPEF tax base third persons
/4G1 – IRPEF third persons
