BR-18

EN 16931-1 layer: en16931

Checked against Peppol BIS Billing 3.0 2026.5

What does BR-18 mean? The Seller tax representative name (BT-62) shall be provided in the Invoice, if the Seller (BG-4) has a Seller tax representative party (BG-11)

Why did my invoice fail BR-18?

If the Seller (BG-4) has a Seller tax representative party (BG-11), that representative's name (BT-62) must be provided. A tax representative is a party accountable for VAT on the seller's behalf (typically for non-established sellers), so it must be identifiable by name. The rule guarantees the representative can be named whenever the group is used.

Official rule text

The Seller tax representative name (BT-62) shall be provided in the Invoice, if the Seller (BG-4) has a Seller tax representative party (BG-11)

Common causes

• A cac:TaxRepresentativeParty block was added but cac:PartyName/cbc:Name is missing.
• The representative's name was placed in a different element such as a contact name rather than PartyName.
• An empty TaxRepresentativeParty was emitted by default even though no representative exists.

How do I fix it?

<cac:TaxRepresentativeParty>
  <cac:PartyName>
    <cbc:Name>VAT Rep GmbH</cbc:Name>
  </cac:PartyName>
</cac:TaxRepresentativeParty>
