Withholding Tax Not Auto-Calculating for Philippines BU

Dear Oracle Community,

We have configured the withholding tax setup for our newly created Business Unit of Philippines. The tax authority (BIR), withholding tax codes, tax rules, and supplier-level tax configurations have been defined.

However, during invoice creation in Payables, the withholding tax is not getting automatically calculated. We have reviewed the following setups:

• Withholding Tax Code (e.g., EWT-5%) created with valid rates
• Setup for manage tax regime, tax , configuration owner,tax reporting and withholding tax option are properly done
• Supplier and Supplier Site assigned correct withholding tax information
• Business Unit, Legal Entity, and Ledger mapped correctly
• Tax Authority (BIR – Bureau of Internal Revenue) properly defined
