PEPPOL-EN16931-P0104

Tax category does not match the exemption code (PEPPOL)

The exemption reason code given (e.g. VATEX-EU-AE for Reverse Charge or VATEX-EU-IC for intra-Community supply) requires a particular tax category – the invoice shows a different one.

What to do now

Tip: Category and exemption code always go together: AE with Reverse Charge, K with intra-Community supply, G with export, O with outside the scope of VAT, E with all other exemptions.

Who has to fix this?

The issuer of the invoice has to fix this. If the invoice is sent through a Peppol access point, the access point will otherwise reject it before delivery.

Where this rule comes from

This rule comes from the Peppol rule set BIS Billing 3.0, which goes beyond EN 16931. It is checked as soon as an invoice is sent as Peppol BIS Billing 3.0 through the Peppol network.
