What is BR-E-09?
BR-E-09 is a fatal validation rule defined in the EN 16931 specification. It validates the TaxAmount element under TaxSubtotal[cac:TaxCategory > ID='E'] 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='E']/cbc:TaxAmount
Why This Error Matters
Invoice will be rejected. VAT exempt (category E) transactions must include all mandatory elements in the VAT breakdown. Missing elements prevent tax authorities from verifying exempt status compliance.
BR-E-09 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.
