Warning

UBL-CR-237: Leave the tax scheme name out of the buyer's tax details

In short

Warning: worth checking.

UBL-CR-237 means the tax scheme in the buyer's tax details in your UBL invoice or credit note contains a name element (Name), which EN 16931 does not use there. Remove cbc:Name from that cac:TaxScheme without removing the scheme identifier, cbc:ID.

What it means

This rule checks that cac:TaxScheme inside the buyer's cac:PartyTaxScheme does not contain cbc:Name. For the buyer's VAT number (BT-48), the scheme is identified by cbc:ID with the value VAT. This test checks only for the Name element, not the scheme identifier. It applies to UBL invoices and credit notes.

Why it matters

EN 16931 uses the tax scheme identifier rather than a separate tax scheme name in the buyer's tax details.

How to fix it

Check whether your invoicing software can omit the name from the buyer's tax scheme export. If it cannot, ask your software supplier to change the export. If you build the XML yourself, delete cbc:Name from cac:AccountingCustomerParty/cac:Party/cac:PartyTaxScheme/cac:TaxScheme. For the buyer's VAT number (BT-48), keep cbc:ID with the value VAT. Export or save the file again and recheck it.
