What is BR-G-09?
BR-G-09 is a fatal validation rule defined in the EN 16931 specification. It validates the TaxAmount element under TaxSubtotal[cac:TaxCategory > ID='G'] in the UBL invoice XML.
When this rule fires, the invoice is rejected by Peppol access points and never reaches the buyer.
Target path: //cac:TaxTotal/cac:TaxSubtotal[cac:TaxCategory/cbc:ID='G']/cbc:TaxAmount
Why This Error Matters
Invoice will be rejected. Export outside EU (category G) transactions require complete zero-rate VAT breakdown with exemption justification. Missing elements prevent customs and tax verification of export treatment.
BR-G-09 is a hard failure — the invoice must be corrected and re-sent before it can reach the recipient.
Invoice Navigator can automatically correct this error in your pipeline. The fix is applied with full audit evidence, so your compliance trail remains intact.
