Automated Verification of 48b EStG Certificate for Withholding Tax Determination

The system must automatically verify whether a supplier holds an active 48b EStG certificate. If a valid certificate is found, no withholding tax should be applied. If the supplier does not have an active certificate, a 15% withholding tax must be applied.

 Guidance Required:

• Instructions on how to maintain the 48b EStG construction tax certificate in the supplier master data.
• Configuration steps to ensure the system automatically posts withholding tax to the appropriate withholding tax liability account.
