The Calculate PIS field determines the calculation of PIS/PASEP (Social Integration Program) for routines using registered classes, and the PIS Perc. field defines the tax percentage to be applied.
When including bills receivable and this field is indicated as Yes, the system calculates PIS amounts from the bill's value according to the percentage defined in PIS Perc. field and the Client Register, where the Calculate PIS field must be set as Yes.
The system uses the MV_PISNAT parameter to indicate the class for classifying the PIS bill.
Example - Application of the Calculate PIS field when adding bills receivable:
When entering Yes in the Calculate PIS field and 0.65% in the PIS Perc. field, during the inclusion of a bill receivable of R$ 1,000.00, the system calculates R$ 6.50 for the PIS referring to this bill.
