BR-AE-04 Reverse charge document charge needs seller and buyer tax identifiers

An invoice with a document level charge (BG-21) whose VAT category code (BT-102) is "Reverse charge" (AE) shall contain the Seller VAT identifier (BT-31), the Seller tax registration identifier (BT-32) and/or the Seller tax representative VAT identifier (BT-63), and the Buyer VAT identifier (BT-48) and/or the Buyer legal registration identifier (BT-47).

Problem Description

ERROR

EN 16931 VAT category rule

Context and Significance

This is the counterpart of BR-AE-03 for document level charges: reverse charge shifts VAT to the buyer, so both parties must be tax-identified when a charge carries category AE. In practice, the error occurs when a freight or packaging charge is coded AE but the buyer identifier is missing from the XML.

Solution

Populate a seller tax identifier (BT-31, BT-32 or BT-63) and a buyer identifier (BT-48 or BT-47) on the invoice carrying the reverse charge charge.

Valid Examples

Invalid Examples

AE charge where the seller VAT ID is present but no buyer identifier (BT-48/BT-47) is given
