Peppol BIS Billing 3.0, May 2026 release, EN 16931 model bound to UBL
Severity note: fatal, from the Flag column of the Peppol BIS Billing 3.0 UBL rules index retrieved 2026-10-18.
Each VAT breakdown (BG-23) must have a VAT category tax amount (BT-117). The message says "shall have" and starts with "Each". It ends with a period. It does not say "Document level". The context is a tax subtotal. The published test checks that cbc:TaxAmount exists. It does not calculate the amount.
Put a VAT category tax amount (BT-117) on each VAT breakdown.
Illustration of the condition in the official statement. Not an example published by the source.
