What is BR-IC-10?
BR-IC-10 is a fatal validation rule defined in the EN 16931 specification. It validates the TaxExemptionReasonCode element under ID='K'] > TaxCategory in the UBL invoice XML.
When this rule fires, the invoice is non-compliant and will be rejected by Peppol access points and national validation services. The sending system receives a rejection response and the invoice does not reach the buyer.
Target path: //cac:TaxTotal/cac:TaxSubtotal[cac:TaxCategory/cbc:ID='K']/cac:TaxCategory/cbc:TaxExemptionReasonCode
Why This Error Matters
Invoice will be rejected. Intra-community supply (category IC) requires both seller and buyer VAT numbers for reverse charge mechanism. Missing elements prevent cross-border VAT compliance verification.
BR-IC-10 is a hard failure. Invoices that trigger this rule are rejected at the access point and never reach the recipient. In Peppol networks, this means your sending system receives an MLR (Message Level Response) with a rejection status. The invoice must be corrected and re-sent, adding delay to your payment cycle.
