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 2026-10-17.
A VAT breakdown whose category is "Intra-community supply" must include a VAT exemption reason code (BT-121) that means "Intra-community supply", or the exemption reason text (BT-120) "Intra-community supply" (or the equivalent standard text in another language). The official message says "with the VAT Category code". The published test is exists(cbc:TaxExemptionReason) or (exists(cbc:TaxExemptionReasonCode) ) with a space before the closing parenthesis. It only checks that one of those two elements exists. It does not compare the text.
On the K VAT breakdown, provide an exemption reason code that means "Intra-community supply", or set the exemption reason text to "Intra-community supply" or the equivalent standard text in another language.
Illustration of the condition in the official statement. Not an example published by the source.
Fails the stated condition. A VAT breakdown category code is K and both the exemption reason text and the exemption reason code are absent.
Passes the stated condition. That breakdown includes the exemption reason text "Intra-community supply" (or the equivalent standard text in another language), or a reason code that means "Intra-community supply".
